With the rapid development of China's automobile industry, the market demand potential is huge. In the production and processing of auto parts, the maintenance and cleaning of metal parts is a very important link. WithIndustrial cleaning agentdevelopment, as well as the strengthening of people's awareness of environmental protection, people on the useCleaning agentAnd cleaning equipment are put forward higher requirements.
(I) environmental protection metal partsCleaning agentGeneral request
The first is that the cleaning equipment and the parts to be cleaned will not be corroded, and the second is that the cleaning process will not produce residues, including insoluble substances, dirt, and coatings that are not conducive to subsequent processing. Next is the cleaning efficiency is high, and the cleaning is thorough enough. Finally, low cost, in line with environmental protection requirements, harmless to the human body, the smell is relatively mild.
In the metal processing industry, with the increasing demand for zero performance and processing efficiency, the cleaning agent is no longer a simple decontamination effect, but has been given more requirements. According to the characteristics of metal materials, it is required that the cleaning agent used not only can effectively decontaminate, but also needs to prevent rust on the surface of metal parts and enhance the corrosion resistance of products, which puts forward higher requirements for the additives added to the cleaning agent.
Classification of (II) cleaning equipment and requirements for cleaning agents
At present, the commonly used metal cleaning equipment includes immersion cleaning equipment, spray cleaning equipment, high-pressure spray cleaning equipment and ultrasonic cleaning equipment.
Intrusive cleaning is generally used for multi-cavity parts. This method has higher requirements for the cleaning ability of the cleaning agent and the ability to emulsify miscellaneous oil, but not for defoaming performance. However, a cleaning agent with a strong ability to emulsify miscellaneous oil has a disadvantage that the cleaning ability will gradually decrease, so the service life is short.
When cleaning the parts in the automobile gearbox, most of the through spray cleaning method is used, and rinsing and drying are also carried out after cleaning. Spray cleaning equipment is generally equipped with skimmer, suitable for the use of anti-miscellaneous oil cleaning agent, but also consider the ability to defoaming. Cleaning agent has its own best use temperature range, its cleaning ability is increased with the increase of temperature, but once beyond this range, the cleaning ability will decline. Therefore, it is also important to master the appropriate cleaning temperature.
High-pressure spray cleaning is mostly used to remove dirt on the surface of parts and components while also removing burrs on the metal surface. The parts are mostly positioned and sprayed at fixed points. The cleaning agent is required to have good foam resistance under high pressure.
(III) requirements for cleaning agents in subsequent processing procedures
In some specific process conditions, the choice of cleaning agent must also consider the impact on the subsequent processing process. For example, in the production of transmission gear parts, there are two steps in the process of grinding teeth and shot blasting. After these two processes, the gear needs to be sprayed and cleaned. Then, in the middle between grinding and shot blasting cleaning, it is necessary to consider the use of the cleaning agent will not affect the subsequent shot blasting process, such as drying will not leave on the surface of the parts with viscous cleaning agent residue or cover film. These will destroy the quality of the shot peening process, resulting in product defects.
