Rust can damage the machine tool components and reduce the equipment’s lifespan, leading to costly repairs and replacements. However, using rust preventatives can help protect machine tools from rust and corrosion, prolonging their lifespan and reducing maintenance costs.
Machine tools are essential for manufacturing, but they are often subjected to harsh operating conditions, including exposure to moisture, heat, and dust, which can cause rust and corrosion.
The corrosive process can cause damage to components and reduce their lifespan, which can ultimately result in costly repairs or replacements. Fortunately, rust preventatives can help protect against corrosion and extend the life of your equipment.
In this blog post, we’ll explore the various uses and applications of rust preventatives, how to choose the best one for your machinery and how to use them properly.
What are Rust Preventatives?
Rust preventatives are a type of lubricant that contains additives to help protect metal surfaces from rust and corrosion. They are designed to create a barrier between the metal and the elements, preventing moisture and oxygen from coming into contact with the metal and causing rust.
There are two main types of rust preventatives: film-forming and contact inhibitors. Film-forming rust preventatives create a protective film on the metal surface, while contact inhibitors work by neutralizing the chemical reaction that causes rust.
Uses of Rust Preventatives
Rust preventatives can be used in a variety of applications, from industrial machinery to automotive components. Here are some common uses of rust preventatives:
Machine Tools
Machine tools, such as lathes, milling machines, and drill presses, are often subjected to harsh operating conditions that can cause rust and corrosion. Rust preventatives can be applied to these machines to protect their metal components from rust and prolong their lifespan.
Automotive Components
Rust preventatives can also be used on automotive components such as engine parts, brake systems, and suspension components. These parts are often exposed to moisture and road salt, which can cause rust and corrosion over time. By applying rust preventatives, you can protect these components and extend their lifespan.
Storage of Metal Parts
Metal parts that are not in use, such as spare parts or equipment that is being stored, can be susceptible to rust and corrosion. Rust preventatives can be applied to these parts to protect them while they are in storage, ensuring that they are ready to use when needed.
Applications of Rust Preventatives
Rust preventatives can be applied in a variety of ways, depending on the specific application. Here are some common methods of application:
Spray Application
Rust preventatives can be applied using a spray bottle or sprayer. This method is useful for large components or areas that are difficult to reach with other methods.
Dip Application
In dip application, the metal part is submerged in a bath of rust preventative. This method is useful for small parts or components that require a more thorough coating.
Brush or Wipe Application
For small or hard-to-reach areas, rust preventatives can be applied using a brush or cloth. This method is useful for precise application or when a spray or dip application is not practical.
How to Choose the Best Rust Preventative for You
When selecting a rust preventative for machining applications, there are several characteristics you should compare to determine which product is the best fit for your needs. These characteristics include:
Type of Rust Preventative
There are different types of rust preventatives, such as oil-based, solvent-based, water-based, and dry film. Each type has its advantages and disadvantages depending on the application. For example, oil-based rust preventatives are ideal for heavy-duty applications as they offer better protection and can withstand extreme conditions, while water-based rust preventatives are more environmentally friendly and easier to remove.
Corrosion Protection
The rust preventative you select should provide excellent corrosion protection. It should form a barrier that prevents moisture and other corrosive agents from coming into contact with the metal surface. It should also be able to resist wear and tear to ensure long-lasting protection.
Surface Compatibility
The rust preventative should be compatible with the metal surface it is applied to. It should not react with the metal, causing it to corrode or discolor. If the rust preventative is not compatible with the metal, it may not provide adequate protection.
Temperature Range
The rust preventative should be able to withstand the temperatures that the machine tool is exposed to. If the machine tool operates at high temperatures, the rust preventative should be able to resist heat without breaking down or evaporating. Similarly, if the machine tool operates at low temperatures, the rust preventative should not become too thick or hard.
Application Method
The rust preventative should be easy to apply using the available application methods, such as spray, brush, or wipe. The application method should be practical, efficient, and cost-effective.
Drying Time
The rust preventative should have a reasonable drying time to allow for efficient application and to avoid causing any delays in production.
Environmental Considerations
Consider the environmental impact of the rust preventative you select. Choose a product that is eco-friendly, does not contain harmful chemicals, and can be easily disposed of.
Choosing the Right Rust Preventative
By comparing these characteristics, you can select a rust preventative that is most suitable for your machining application needs. It is always best to consult with a reputable supplier or manufacturer for recommendations to ensure that you select the best product for your needs.
Because there are different types of rust preventatives available based on the application needed, it is essential to choose the right rust preventative that is suitable for the machine tool and the environment in which it is used.
For example, if the machine tool is used in a dusty or dirty environment, an oil-based rust preventative may be more suitable as it provides a thicker and more durable coating. On the other hand, a water-based rust preventative may be more suitable for machine tools used in a clean environment.
Fusion offers a variety of rust preventatives based on your industry needs.
How to Properly Use Rust Preventatives
Here are the steps to follow for using rust preventatives on machine tools:
Clean the Surface
Before applying a rust preventative, it is essential to ensure that the metal surface is clean and free of any dirt, grease, or rust. If the surface is dirty, the rust preventative may not adhere properly, reducing its effectiveness.
To clean the surface, use a degreaser or a cleaning solvent and a cloth or brush. It is essential to wear gloves and protective gear while handling these chemicals. If the surface has rust, it is advisable to remove it using sandpaper or a wire brush.
Apply the Rust Preventative
There are different methods of applying rust preventatives, such as spray application, dip application, or brush or wipe application. The method chosen will depend on the size and shape of the machine tool, as well as the type of rust preventative being used.
Spray application is ideal for large machine tools or for hard-to-reach areas. Dip application is useful for small machine tool components, while brush or wipe application is ideal for precise application or when spray or dip application is not practical.
It is essential to follow the manufacturer’s instructions while applying the rust preventative to ensure that it is applied correctly and uniformly. It is also essential to ensure that the machine tool is adequately covered with the rust preventative, leaving no bare spots.
Store the Machine Tool
Once the rust preventative has been applied, it is essential to store the machine tool properly to prevent rust and corrosion. If the machine tool is stored outdoors, it should be covered or placed in a protective enclosure. If the machine tool is stored indoors, it should be placed in a dry and well-ventilated area.
Conclusion
Rust preventatives are an effective way to protect your machinery and metal components from rust and corrosion. They can be used in a variety of applications and applied using different methods, depending on the specific needs of your equipment. By using rust preventatives, you can help ensure the longevity of your machinery and save money on costly repairs or replacements.
It is important to clean the surface before applying the rust preventative, choose the right rust preventative, apply it correctly using the appropriate method, and store the machine tool properly to ensure its effectiveness.
