How is degreasing agent used in mechanical manufacturing?

Application of degreasing agent in machinery manufacturing

Degreasers play a vital role in the mechanical manufacturing process. They are mainly used to remove grease, dirt, dust and other contaminants from metal surfaces and parts to ensure the quality of subsequent processing, painting or assembly. Mechanical manufacturing is a complex process involving a variety of materials and processes. The application of degreasers runs through multiple links, including raw material processing, processing, assembly and finished product processing. The following are the specific applications of degreasers in mechanical manufacturing and their importance.

1. Raw material processing

In the initial stage of mechanical manufacturing, the surface of metal raw materials (such as steel, aluminum, copper, etc.) is usually attached with grease, anti-rust oil, cutting fluid or other pollutants. If these pollutants are not removed in time, they may affect the quality of subsequent processing, such as welding, stamping, cutting, etc. The application of degreasing agent in this stage is mainly to thoroughly remove grease and dirt on the surface of raw materials through soaking, spraying or wiping, etc., to ensure the cleanliness of the material and provide a good foundation for subsequent processing.

2. Parts processing

In the process of mechanical manufacturing, the processing of parts (such as cutting, grinding, stamping, forging, etc.) will produce a large amount of metal chips, cutting fluid and lubricant residues. If these residues are not cleaned in time, they may affect the dimensional accuracy and surface quality of parts, and even cause wear of processing equipment. The application of degreasing agent at this stage is mainly to clean parts through cleaning equipment (such as ultrasonic cleaning machine, spray cleaning machine, etc.), remove surface oil and metal chips, and ensure the cleanliness and processing accuracy of parts.

3. Surface treatment

Surface treatment processes in mechanical manufacturing (such as electroplating, spraying, phosphating, etc.) have extremely high requirements for the surface cleanliness of parts. If there is grease or other contaminants on the surface of the parts, it may cause problems such as reduced coating adhesion, uneven electroplating or incomplete phosphating film. The application of degreasing agent before surface treatment is mainly through immersion, spraying or ultrasonic cleaning to thoroughly remove grease and dirt on the surface of parts to ensure the quality of surface treatment.

4. Assembly process

During the assembly process of mechanical equipment, the cleanliness of parts and components directly affects the quality of assembly and the performance of the equipment. If there is grease or dirt on the surface of parts and components, it may lead to problems such as reduced assembly accuracy, poor sealing or unstable equipment operation. The application of degreasing agent before assembly is mainly to remove grease and dirt on the surface of parts and components by cleaning equipment or manual cleaning to ensure assembly accuracy and equipment performance.

5. Finished product processing

During the finished product processing stage of mechanical equipment, grease, dust or other pollutants may adhere to the surface of the equipment. If these pollutants are not cleaned in time, they may affect the appearance quality and service life of the equipment. The application of degreasing agent in the finished product processing stage is mainly to remove grease and dirt on the surface of the equipment by cleaning the equipment or manual cleaning to ensure the appearance quality and service life of the equipment.

6. Special applications

In some special mechanical manufacturing processes, the application of degreasing agents also has special significance. For example, in precision machinery manufacturing, the cleanliness requirements of parts are extremely high, and the application of degreasing agents needs to be more refined and strict. In aerospace manufacturing, the materials of parts are usually high-strength alloys, and the selection and application of degreasing agents need to take into account the particularity of the materials and the complexity of the process. In automobile manufacturing, the cleanliness of parts directly affects the performance and safety of the vehicle, and the application of degreasing agents needs to be more strict and standardized.

Types and selection of degreasing agents

There are many types of degreasing agents, which can be divided into the following categories according to their chemical composition and use:

1. Alkaline degreasing agent: mainly used to remove grease and dirt on metal surfaces, suitable for cleaning steel, aluminum, copper and other materials.

2. Acidic degreasing agent: mainly used to remove oxides and rust on metal surfaces, suitable for cleaning stainless steel, copper and other materials.

3. Solvent-based degreaser: Mainly used to remove grease and dirt from metal surfaces. Suitable for cleaning various materials, but attention should be paid to its volatility and environmental friendliness.

4. Water-based degreaser: Mainly used to remove grease and dirt from metal surfaces, suitable for cleaning various materials, environmentally friendly and safe.

When choosing a degreaser, you need to choose it according to the specific application scenario and material characteristics. For example, for precision machinery manufacturing, you need to choose a degreaser with good cleaning effect and no corrosiveness to materials; for automobile manufacturing, you need to choose a degreaser with good environmental protection and stable cleaning effect.

Precautions for the application of degreasing agent

When using degreasing agents in mechanical manufacturing, the following points should be noted:

1. Safety: Degreasers usually contain chemical ingredients. When using them, you need to pay attention to their volatility and corrosiveness to avoid harm to the human body and the environment.

2. Environmental protection: With the improvement of environmental protection requirements, it has become a trend to choose environmentally friendly degreasers. It is necessary to pay attention to the environmental protection and biodegradability of the degreasers.

3. Cleaning effect: The cleaning effect of the degreasing agent directly affects the quality of mechanical manufacturing. It is necessary to select a degreasing agent with good cleaning effect and high stability.

4. Economical efficiency: The selection of degreasing agent also needs to consider its economic efficiency. Choose a degreasing agent with high cost performance to reduce production costs.

in conclusion

The application of degreasing agent in mechanical manufacturing runs through multiple links, from raw material processing to finished product processing, and the role of degreasing agent cannot be ignored. By rationally selecting and applying degreasing agent, the quality and efficiency of mechanical manufacturing can be effectively improved, and the performance and service life of equipment can be ensured. With the continuous development of mechanical manufacturing technology, the application of degreasing agent will also be continuously optimized and innovated, providing strong support for the development of the mechanical manufacturing industry.
