When it comes to maintaining a successful production, cutting costs is essential – and optimizing operations through detailed TCO analysis is the key to achieving long-term savings.

We may have deviating views on how clean is clean. And we do. That is why we always assess the requirements where we talk to you about what cleanliness is and what it means to you. This is a part of our Pure Performance Concept that we lean ourselves onto to achieve high performance. Let’s take a point of exit in manufacturing.

In this industry, the metal surfaces need to be free from cutting oils, grease, and other emulsions or lubricants. In some cases, surfaces may need to be free of all contaminants, while in others, a certain level of impurities may be acceptable. However, this is no easy task, nor should it be perceived as such. That is why we suggest and present the best water-based cleaning solution based on a Product Selector Report from our tech lab. The report is based on a sample of i.e the emulsion used, and metal parts produced in your facility. So, to answer the question ‘how clean is clean’, well, it depends on your specific cleaning needs.

When considering the impact of poor cleaning, it is important to focus on the cleaner rather than the machine. Clean parts are crucial for the next step in the production process. Poor cleaning of these parts can lead to a variety of challenges that slow down productivity.

As a production manager, you know the importance of cleaning industrial parts. However, sometimes the cleaning quality might not meet the required standards, leading to the time-consuming need for manual re-cleaning. And even worse, if you do not have high-quality cleaners, your cleaning machine may not do the job properly. Either you will need to clean the parts twice or do it manually by hand. Increasing manhour costs, energy costs, and water consumption which all add financial pressure. That is why it is important to prioritize quality in cleaning.

But it does not stop there. Poor cleaning quality affects later steps in the production process, such as welding, painting, assembly, and more. Contaminants can interfere with the fit and function of parts, causing delay in production.

Be careful here: Don’t fall into the trap of thinking that you can just clean metal parts at high temperatures. While it may work, it will lead to higher energy costs and water consumption due to evaporation of both water and the cleaner added; the desired result is no longer a guarantee. With the right products, you can clean at low temperatures and avoid these side effects.

Let’s clarify the key points. You are looking for high-quality cleaning solutions to improve your business operations, and that is exactly what we offer. Our water-based cleaners have many advantages.

First, our products allow you to clean metal parts from 35°C depending on the product we choose for you. Here, already, you are quite far, since this temperature is lower you can save quite a lot amount of energy. You might wonder about the bacteria. With proper cleaning and maintenance of the environment, you can keep bacterial problems under control.

Second, you can also be confident that the water-based cleaner you receive is chosen to match your specific needs. We test samples of the oils and emulsions from your facility in our tech lab to ensure optimal results for your cleaning requirements.

Another advantage of our products is their ability to separate oil from water, which is crucial during product selection. Once our products separate the oil, you can easily skim it off using an oil skimmer. This step is important because removing the oil extends the bath’s lifetime, resulting in fewer interruptions for bath changes.

When it comes to maintaining a successful production, cutting costs is essential – and optimizing operations through detailed TCO analysis is the key to achieving long-term savings.

Maintaining clean engines is essential for ensuring optimal performance and longevity. Engines are critical components in various industrial applications, powering machinery and equipment that drive production processes. A clean engine operates more efficiently, reducing energy consumption and minimizing the risk of overheating, which can lead to costly downtime and repairs.

Regular cleaning of engines helps prevent the accumulation of dirt, grease, and other contaminants that can impair functionality. Contaminants can cause increased friction, leading to wear and tear on engine components, which may result in premature failure. This is why implementation of a routine cleaning schedule is important; businesses can enhance the reliability of their operations and extend the lifespan of their engines.

Engine degreasing is a vital aspect of this maintenance process. Effective degreasing removes built-up grime and oil, allowing engines to run cooler and more efficiently. This not only improves performance but also helps in identifying potential issues early, enabling timely maintenance and reducing the likelihood of unexpected breakdowns.

Engine degreasing is a critical process in industrial cleaning, aimed at removing grease, oil, and other contaminants from engine components. Various techniques and products are employed, each with their own advantages and disadvantages.

Traditional methods;  

Solvent-based cleaning:

Passivation is a process that treats the surface of aluminium to create a protective layer that prevents corrosion and improves durability. Anodizing involves immersing aluminium in an electrolyte solution and passing an electric current through it to stimulate the formation of aluminium oxide. Chemical treatments involve applying a specific solution to the aluminium oxide. Mechanical polishing removes impurities to allow for the formation of protective oxide layer.

Environmental considerations in passivation include the use of chemicals and waste disposal. It is important to properly handle and dispose of any chemicals used in the process to minimize environmental impact. Additionally, utilizing more eco-friendly passivation methods and practices can help reduce the overall environmental footprint of aluminium passivation processes.

The process of passivation for aluminium involves treating the surface to create a practice oxide layer that enhances corrosion resistance and durability. The steps of passivation for aluminium typically include cleaning the surface to remove any contaminants, followed by one of the passivation methods such as anodizing, chemical treatments, or mechanical polishing.

It is essential to follow proper cleaning procedures and select appropriate passivation methods to ensure the effectiveness of the protective layer. Attention should also be given to environmental considerations, such proper chemical handling and disposal, to minimize any negative impact on the environment.

There are several key benefits to consider for aluminium surface passivation. Some of the main advantages include:

Corrosion resistance: The nature of aluminium is that it forms a thin layer of protective oxide which helps prevent corrosion and rusting to some degree. This extends the lifespan of the aluminium and maintains its appearance over time. However, passivation is still important as it helps improve the overall corrosion resistance of aluminium, making it more durable.

Improved durability: The protective oxide layer created through passivation enhances the overall durability of aluminium, making it more resistant to wear and tear from environmental factors such as moisture, chemicals, and temperature fluctuations.

Enhanced appearance: Passivation can give aluminium surfaces a more aesthetically pleasing finish by creating a smooth and uniform oxide layer. This can be particularly advantageous for industries where appearance is important.    

Maintenance of properties: Passivation helps maintain the mechanical and physical properties of aluminium, ensuring that it performs well under various conditions and retains its original characteristics.

At DST-CHEMICALS, we can assist customers with aluminum passivation through our specialized product, DST-PAS. DST-PAS is designed to effectively protect, ensuring long-lasting durability and performance.

Cathodic protection is a corrosion prevention technique used to protect metal structures from deteriorating due to contact with corrosion-causing agents like water, oxygen, and chemicals. It works by creating a negative voltage potential on the metal surface, effectively slowing down the corrosion process and extending the lifespan of the structure.

Cathodic protection is important because it helps prevent costly repairs and replacements of metal structures, particularly in industries like oil and gas, water, and marine structures. It is commonly used for offshore oil platforms, pipelines, ship hulls, and underground tanks where metal structures are exposed to harsh environments. By implementing cathodic protection systems, industries can ensure the safety and longevity of their metal assets.

There are two main methods of cathodic protection: galvanic and impressed current.

In galvanic protection, a more reactive metal (Zinc and copper) is connected to the metal structure, creating a galvanic cell where the sacrificial anode corrodes instead of the protected metal.

In impressed current cathodic protection (ICCP), an external power source applies a direct current to the metal structure, causing the corrosion agents to be repelled.

The key difference between the two types lies in the source of the protective current: galvanic protection relies on the natural potential difference between metals, while impressed current protection requires an external power source to drive the protective current.

Pros of galvanic anode cathodic protection include its simplicity, low maintenance requirements, and cost-effectiveness compared to impressed current systems. It is also suitable for smaller structures and remote locations where access to power sources may be limited.

However, there are some cons to consider. Galvanic anodes have a limited lifespan and may need to be replaced periodically. They also provide a fixed level of protection, which may not be sufficient for larger structures or environments with high corrosion rates.

Galvanic anode cathodic protection is best used in situations where a simple and cost-effective corrosion prevention method is needed, such as for smaller structures, remote locations, or where power sources are not readily available. It is a suitable choice when the level of protection provided by sacrificial anodes meets the requirements for the specific application.

Pros of impressed current cathodic protection include greater control and adjustability of the protective current, suitable for larger structures or areas with high corrosion risk., and longer-lasting protection compared to galvanic systems.

However, there are also some cons to consider. Higher initial installation and maintenance costs, requires regular monitoring and maintenance to ensure proper functioning, and potential for overprotection, which can lead to hydrogen embrittlement or other issues.

Impressed current cathodic protection is recommended when galvanic protection is not sufficient to provide the required level of corrosion prevention, especially in high-risk environments or critical infrastructure where precise control over the protective current is necessary. It is often used in industries such as oil and gas, marine, and transportation to protect vital structures from corrosion and extend their service life.

Aluminium oxidation refers to the process in which aluminium reacts with oxygen in the air, forming a thin layer of aluminium oxide on the surface of the metal. This layer is typically white or grey in colour and can give the aluminium a dull and pitted appearance. While aluminium oxide is a protective barrier that helps prevent further corrosion, excessive oxidation can lead to deterioration of the metal.

Note that aluminium oxidation is different from rust, a form of iron oxide that occurs when iron reacts with oxygen and moisture. Rust is typically reddish-brown and is commonly associated with ferrous metals like steel. Corrosion, on the other hand, is a general term that refers to the degradation of metals through chemical reactions with their environment.
Read more about corrosion and rust removal in industrial settings here

The appearance of aluminium oxidation can vary depending on the severity of the corrosion. In its initial stages, oxidation may appear as a dull, whitish film on the surface of the aluminum. As the corrosion progresses, the oxidation may develop into a more noticeable powdery or flaky texture, eventually leading to pitting or discoloration of the metal surface.

 
Aluminium oxidation occurs due to the natural reactivity of aluminium with oxygen in the air. When aluminium is exposed to moisture and air, a chemical reaction occurs, forming aluminium oxide on the surface of the metal. Factors such as exposure to saltwater, pollution, and harsh chemicals can accelerate the oxidation process, leading to more severe corrosion. Regular cleaning and maintenance can help prevent and remove oxidation from aluminium surfaces, preserving the metal’s appearance and structural integrity.

Here are 3 methods for cleaning and removing oxidation from aluminium surfaces: Pressure washing, chemical cleaning, and steam cleaning.

Pressure washing: Pressure washing involves using high-pressure water spray to clean surfaces, including aluminium. The force of the water can dislodge dirt, grime, and oxidation from the surface, making it an effective method for cleaning large areas quickly. However, pressure washing may not be suitable for delicate or intricate aluminium surfaces, as the high pressure can potentially damage the metal or strip away protective coatings.   

Chemical cleaning: Chemical cleaning involves using specialized cleaners and polishes specifically designed for aluminium surfaces. These cleaners work by breaking down oxidation and other contaminants. Chemical cleaning is a targeted approach that can be used on smaller or more delicate aluminium surfaces where pressure washing may be too harsh. 

Steam cleaning: Steam cleaning uses high temperature to clean and sanitize surfaces, including aluminium. The heat and moisture help to loosen dirt and oxidation, making it easier to remove with a cloth or towel. Steam cleaning is a chemical-free method that can be as powerful as pressure washing for stubborn or deep-seated oxidation.  
 
Each method has its own advantages and considerations, so it is essential to choose the most suitable method based on the specific requirements of the aluminium surface being cleaned. Consider factors such as the size of the area, the level of oxidation, the type of aluminium, and any protective coatings or finishes when selecting the cleaning method.  

After cleaning aluminium surfaces to remove oxidation and dirt, there are several methods to restore shine to the metal.  

The DST-WAY: At DST-CHEMICALS, we have products to cover your exact needs. Even if you are looking for a way to reenergize your aluminium parts. We recommend using non-alkaline products. The lower the pH-value, the better. As a rule of thumb, we’d say a pH-value ranging from 2-5 depending on the part. If you are looking to prevent additional oxidation on aluminum surfaces, we suggest using our DST-Alu Rinse. This product is a 2% solution that provides temporary protection against further oxidation on aluminum. The mechanism involves penetrating the rust and corrosion, effectively breaking down the oxide layers that have accumulated on the metal.

Aluminium brightener: Aluminium brighteners are commercial products that can help to remove oxidation and restore shine to aluminium surfaces. Follow the manufacturer’s instructions for proper application, which involve diluting the brightener with water, applying it to the surface, and rinsing it off after a specific time. Aluminium brighteners can be effective in brightening and shing aluminium surfaces.  

Aluminium polish paste: Aluminium polish paste is another effective product for shining aluminium surfaces. Apply a small amount of the paste onto a damp cloth and gently rub it onto the aluminium surface in circular motions. The abrasive particles in the paste help to remove oxidation and scratches while restoring shine to the metal. Buff the surface with a clean, dry cloth to reveal a glossy.

Aluminium is known for its natural resistance to corrosion, thanks to the ability to form a thin oxide layer on its surface that protects it from environmental elements. However, aluminium can still corrode under certain conditions. The primary cause of aluminium corrosion is the reaction between the metal and oxygen in the air, leading to the formation of aluminium oxide.

There are several factors that can accelerate aluminium corrosion, including exposure to moisture, saltwater, acidic or alkaline environments, and high temperatures. When aluminium comes into contact with these elements, it can lead to the breakdown of the protective oxide layer and the formation of pitting or surface damage.

Other factors that can contribute to aluminium corrosion include contact with dissimilar metals, improper handling or storage, and mechanical damage to the surface of the metal. It is important to be aware of these causes of aluminium corrosion and take preventive measures to protect your aluminium products from deteriorating over time.

Rust and corrosion are often used interchangeably to describe the deterioration of metals, but there is a distinct difference between the two terms. Rust specifically refers to the corrosion of iron and its alloys, such as steel, when they come into contact with oxygen and moisture. The reddish-brown flakes that form on the surface of iron or steel are called rust.

On the other hand, corrosion is a general term that describes the degradation of any metal when exposed to environmental elements. Unlike rust, corrosion can affect a wide range of metals, including aluminium, copper, brass, zinc, among others. Corrosion can manifest in various forms, such as pitting, flaking, or discoloration, depending on the type of metal and the conditions in which it is exposed.

The main reason why there is a difference between rust and corrosion lies in the chemical composition of the metals themselves. Iron and steel contain a significant amount of iron, which is prone to reacting with oxygen to form iron oxide, or rust. Other metals, like aluminium and copper, have different chemical compositions that result in different corrosion products when they come into contact with environmental elements.

Rust, also known as iron oxide, is a reddish-brown coating that forms on iron and steel when exposed to oxygen and moisture. The process of rust formation, scientifically known as corrosion, occurs when iron reacts with oxygen and water, leading to the breakdown of the metal’s surface. While rust may appear harmless at first glance, it can have a detrimental effect on industrial parts if left untreated.  

Rust can weaken the structural integrity of equipment, causing components to deteriorate and potentially leading to equipment failure. This can result in costly repairs, downtime, and loss of productivity for businesses. In addition, rust can also impact the efficiency and performance of equipment, reducing its lifespan and increasing maintenance costs over time.  
 
The financial and operational risks associated with untreated rust issues are significant. Equipment that is affected by rust may experience decreased efficiency, leading to higher energy consumption and reduced output. In addition, rust can compromise the safety of equipment and pose risks to employees working with or around the affected machinery. Furthermore, untreated rust can escalate into more severe corrosion problems, resulting in the need for costly replacements or repairs.  
 
To protect industrial equipment and maintain operational efficiency, it is crucial to address rust issues properly and effectively. Regular inspection and maintenance, along with proper rust removal techniques, can help prevent the formation of rust and prolong the lifespan of equipment. By investing in rust removal and prevention, businesses can mitigate the financial and operational risks associated with rust issues and ensure the smooth functioning of their equipment. 

When it comes to industrial rust removal, there are several types of rust removers available on the market, each with its own unique properties and applications. Some common types of rust removers include:

Chemical rust removers: These solutions contain acidic or alkaline compounds that break down rust from metal surfaces. Examples of chemical rust removers include phosphoric acid-based products, citric acid solutions, and rust converters.  

Mechanical rust removers: Mechanical rust removers, such as wire brushes, sandpaper, and abrasive pads, physically scrub away rust from metal surfaces. These tools are effective for smaller rust spots and surface-level corrosion.  

Electrolytic rust removers: Electrolytic rust removal involves using an electric current and an electrolyte solution to remove rust from metal surfaces. This method is effective for larger rusted areas and can be used on delicate or complex equipment.  

When selecting the appropriate rust remover for a specific application, there are several factors to consider:  

Type and extent of rust: Consider the type and severity of rust present on the equipment. Some rust is present on the equipment. Some rust removers are more effective for light surface rust, while others are better suited for heavy corrosion. 

Material compatibility: Ensure that the rust remover is compatible with the material of the equipment being treated. Some chemicals can damage certain metals or coatings. 

Safety and environmental impact: Consider the safety and environmental implications of the rust remover. Choose products that are safe to use and environmentally friendly. 

The process of rust removal typically involves applying the rust remover to the affected area, allowing it to penetrate and break down the rust, and then scrubbing or rinsing off the rust residue. For more stubborn rust, multiple applications or a combination of different rust removal methods may be necessary. 

In addition to using rust removers to address existing rust issues, implementing rust prevention strategies is essential for protecting industrial equipment and ensuring its longevity. One of the most effective ways to prevent rust formation is with protective coatings and sealants. These products create a barrier between the metal surface and external elements, such as oxygen and moisture, that can cause corrosion.

Some common types of protective coatings and sealants used for rust prevention include:

Paints and primers: Applying paint or primer to metal surfaces can help protect against rust formation by providing a protective barrier. Epoxy, urethane, and enamel paints are commonly used for industrial applications.  

Corrosion inhibitors: Corrosion inhibitors are chemicals that can be applied to metal surfaces to prevent rust formation. These inhibitors form a protective film on the metal, preventing rust-causing elements from meeting the surface.  

Galvanizing: Galvanizing involves applying a layer of zinc to metal surfaces through a hot-dip or electroplating process. This zinc coating acts as a sacrificial anode, protecting the underlying metal from corrosion.  

Additionally, besides the use of protective coatings and sealants, implementing regular maintenance and inspection routines is crucial for preventing rust on industrial equipment. Regularly inspecting equipment for signs of rust, addressing any issues promptly, and conducting preventive maintenance can help identify and address potential rust risks before they escalate into more severe problems.  

The task of rust removal can often pose significant challenges, given the ease with which rust forms and the difficulty in effectively eliminating it, not to mention the potential for soaring costs. In response to this persistent issue, we have introduced the innovative DST-DERUST solution. This product offers a straightforward yet powerful functionality, boasting three key advantages.

Corrosion is the deterioration of a material, usually a metal, due to a chemical reaction with its environment. There are several types of corrosion, including uniform corrosion, localized corrosion (such as pitting corrosion and crevice corrosion), galvanic corrosion, and stress corrosion cracking. Each type of corrosion can have different mechanisms and causes, but all can lead to significant damage if left unchecked.

Corrosion can have far-reaching consequences on infrastructure and industrial equipment. It can weaken structures, pipelines, and machinery, leading to premature failure and safety hazards. Corrosion can also result in leaks, reduced efficiency, and increased maintenance costs. In extreme cases, corrosion-related failures can cause catastrophic accidents and environmental damage.

The financial impact of corrosion on infrastructure and industrial equipment can be substantial. Repairing or replacing corroded components can be costly, not only in terms of material and labor expenses but also in terms of lost production and downtime. Corrosion-related maintenance and repair costs can quickly add up, affecting the bottom line of businesses and industries.

In addition to financial losses, corrosion poses a significant risk to operational safety and efficiency. Corroded equipment and structures may not perform as intended, increasing the likelihood of accidents and distributions to operations. Corrosion can also compromise the integrity of critical systems, putting personnel and the environment at risk. Ensuring proper corrosion protection measures are in place is essential for maintaining operational safety and efficiency in industrial settings.

Preventing corrosion through effective protection measures can result in significant economic benefits. By safeguarding infrastructure and industrial equipment from corrosion, businesses can avoid costly repair and replacement expenses. Regular maintenance and applying corrosion protection coatings can extend the lifespan of assets, reducing the need for frequent replacements and downtime.

Corrosion not only affects the bottom line of businesses but also has environmental implications. Corrosion-related leaks and failures can result in the release of hazardous materials into the ecosystems, contaminating soil and water sources. This can have far-reaching consequences on wildlife, vegetation, and human health. Implementing corrosion protection measures helps prevent environmental damage by reducing the risk of leaks and spills.

The key to preventing corrosion is to eliminate or control the factors that contribute to the degradation of materials. This can be achieved by implementing various corrosion prevention techniques, including the use of barriers and inhibitors. 
 
Barriers are physical coating or layers applied to the source of a material to prevent contact with corrosive elements. They act as a shield, protecting the underlying material from the environment. Inhibitors, on the other hand, are chemical substances that are added to the environment or applied directly to the material to reduce the rate of corrosion. Inhibitors work by forming a protective film on the metal surface, slowing down the corrosion process.

Surface Coatings: Applying paints, enamels, or other coating materials to the surface of a material can provide an effective barrier against corrosion. These coatings create a protective layer that shields the material from exposure to moisture and chemicals, preventing corrosion.

Cathodic Protection: Is a technique used to control corrosion by making the metal surface the cathode of an electrochemical cell. This can be achieved through sacrificial anodes, where a more reactive metal is connected to the structure to absorb the corrosion, or through impressed currents, where an external power source is used to provide a protective current.

Alloying metal: Alloying is the process of adding other elements to a metal to enhance its corrosion resistance. By altering the composition of the metal, its susceptibility to corrosion can be reduced, making it more resistant to degradation in corrosive environments.

Protective Wraps and Tapes: Wrapping materials like tapes and wraps can be used to physically shield metal surfaces from corrosive elements. These protective wraps create a barrier that prevents direct contact between the metal and the environment, reducing the risk of corrosion.

Corrosion Inhibitors: Corrosion inhibitors are chemicals added to the environment or applied directly to the metal surface to reduce corrosion rate. These inhibitors work by forming a protective layer on the metal surface, preventing corrosive agents from reaching the underlying material. Corrosion inhibitors are commonly used in various industries, such as oil and gas, water treatment, and manufacturing, to protect equipment and infrastructure from corrosion.

The transportation industry, particularly in overseas operations, is highly vulnerable to corrosion due to exposure to harsh environmental conditions such as humidity, saltwater, and varying temperatures. These factors accelerate the corrosion process, leading to structural degradation and potential safety hazards. Additionally, the constant movement of goods and vehicles increases the likelihood of physical damage, which can further exacerbate corrosion issues. Proper corrosion protection measures are essential to ensure the longevity and safety of transportation assets in such challenging environments. 

The offshore industry: Maritime structures, including ships, offshore platforms, and port facilities, are constantly exposed to corrosive saltwater environments. The corrosive nature of seawater can accelerate the degradation of metal surfaces, making corrosion protection essential in the maritime industry.

Oil and gas pipelines are highly susceptible to corrosion due to the harsh operating conditions they are exposed to, such as high temperatures, pressures, and corrosive chemicals. Corrosion in pipelines can lead to leaks, spillages, and environmental contamination, making effective corrosion protection crucial in this industry.
