What are the common uses of degreasing agents in industrial production?

Degreasing agents are widely used in industrial production. Their main function is to remove grease, dirt, wax and other organic pollutants on the surface of materials to ensure the quality and effect of subsequent processing, coating, welding and other processes. The selection and use of degreasing agents are of great significance to improving production efficiency, ensuring product quality and extending the service life of equipment. The following are some common uses of degreasing agents in industrial production:

1. Cleaning before metal processing

During the metal processing process, the surface of raw materials or semi-finished products usually adheres to pollutants such as grease, cutting fluid, and anti-rust oil. These pollutants will affect the subsequent processing accuracy and surface treatment effect. Degreasing agents are widely used in cleaning before metal processing to ensure that the metal surface is clean and oil-free, providing a good foundation for subsequent cutting, stamping, welding, heat treatment and other processes.

For example, in automobile manufacturing, metal sheets need to use degreasing agents to remove rust-proof oil and processing oil on the surface before stamping to ensure the surface quality and dimensional accuracy of stamped parts. Similarly, in mechanical processing, degreasing agents are used to clean cutting fluids and oil stains on the surface of parts for subsequent grinding, polishing or electroplating.

2. Surface treatment before painting

In the coating process, grease and dirt on the surface of the material will seriously affect the adhesion and uniformity of the coating, causing blistering, peeling or defects in the coating. Therefore, degreasing agent plays an important role in surface treatment before painting. It can effectively remove oil stains on the surface of materials such as metal, plastic, glass, etc., providing a clean surface for painting.

For example, in home appliance manufacturing, metal casings need to be cleaned with a degreaser before spraying to ensure the adhesion and appearance quality of the coating. In automotive painting, the body also needs to be degreased before spraying primer to prevent coating defects.

3. Pretreatment before electroplating and chemical plating

Electroplating and chemical plating processes have extremely high requirements for the cleanliness of the material surface. Any grease or dirt will affect the uniformity and bonding strength of the coating. Degreasing agent is one of the key steps in the pretreatment before electroplating and chemical plating, which is used to remove grease and organic pollutants on the material surface.

For example, in the electronics industry, circuit boards need to be cleaned with degreasers before electroplating to ensure the conductivity and reliability of the coating. In hardware products, degreasers are used to remove oil stains on the metal surface to provide a clean surface for electroplating.

4. Cleaning before welding

In the welding process, grease and dirt on the surface of the material will affect the welding quality, resulting in pores, cracks or insufficient strength of the weld. Degreasing agent is used for surface cleaning before welding to remove grease and other contaminants to ensure the quality of the welded joint.

For example, in pipeline welding, degreasing agents are used to clean the oil inside and outside the pipeline to ensure the sealing and strength of the welded joints. In steel structure welding, degreasing agents are used to remove rust-proof oil and processing oil on the surface of steel to improve welding quality.

5. Cleaning before heat treatment

During the heat treatment process, grease and dirt on the surface of the material will carbonize at high temperatures, forming residues that are difficult to remove, affecting the heat treatment effect. Degreasing agents are used for cleaning before heat treatment to remove grease and other contaminants on the surface of the material to ensure the uniformity and quality of the heat treatment.

For example, in bearing manufacturing, degreasing agents are used to clean the oil stains on the surface of bearing parts for subsequent heat treatment. In mold manufacturing, degreasing agents are used to remove grease from the mold surface to improve the surface hardness and wear resistance of heat treatment.

 6. Cleaning of electronic components

During the manufacturing and assembly of electronic components, grease and dirt can affect the performance and reliability of components. Degreasers are used to clean grease, flux and other contaminants on the surface of electronic components to ensure the electrical performance and welding quality of components.

For example, in semiconductor manufacturing, degreasers are used to clean grease and organic contaminants from the surface of wafers to ensure the quality of subsequent photolithography and etching processes. In circuit board assembly, degreasers are used to clean flux residues around solder joints to improve circuit reliability.

7. Surface treatment of plastic products

In the production and processing of plastic products, degreasing agents are used to remove release agents, grease and other contaminants from the plastic surface to improve the surface quality of plastic products and the subsequent processing effect.

For example, in injection molding, the release agent will form an oil film on the surface of the plastic product, affecting the subsequent printing, spraying or bonding process. Degreasing agent is used to clean the release agent on the surface of plastic products to ensure the quality of subsequent processes.

8. Glass and ceramic cleaning

In the production of glass and ceramic products, degreasers are used to remove grease, fingerprints and other contaminants from the surface to improve the transparency and surface finish of the products.

For example, in optical glass manufacturing, degreasing agents are used to clean grease and dirt on the glass surface to ensure optical performance. In ceramic tableware production, degreasing agents are used to remove oil stains on the ceramic surface to improve the adhesion and aesthetics of the glaze.

9. Textile and leather industry

In the textile and leather industries, degreasers are used to remove oils, waxes and other contaminants from the surfaces of fibers and leather to improve dyeing, printing and finishing.

For example, before dyeing textiles, degreasing agents are used to remove grease and wax from the fiber surface to ensure uniformity and color fastness of dyeing. In leather processing, degreasing agents are used to remove grease from the leather surface to improve the adhesion and appearance quality of the finishing.

10. Food and pharmaceutical industry

In the food and pharmaceutical industries, degreasers are used to clean grease and dirt from the surfaces of equipment and containers to ensure a hygienic production environment and product safety.

For example, in food processing, degreasers are used to clean grease residues from production line equipment and containers to prevent cross contamination. In the pharmaceutical industry, degreasers are used to clean oil stains from production equipment and containers to ensure the purity and safety of drugs.

Summarize

Degreasing agents are widely used in industrial production, covering many fields such as metal processing, coating, electroplating, welding, heat treatment, electronics, plastics, glass, textiles, leather, food and pharmaceuticals. By using degreasing agents, grease and dirt on the surface of materials can be effectively removed, production efficiency can be improved, product quality can be guaranteed and equipment service life can be extended. With the continuous development of industrial technology, the types and performance of degreasing agents are also being continuously optimized to meet the needs of different industries and processes.
