       China's automobile industry market demand is huge, in the automobile manufacturing and auto parts production process, there are many parts cleaning process with the development of technology and environmental protection requirements, but also for cleaning equipment and cleaning agent put forward higher requirements, we recommend cleaning agent how to adapt and meet the production process requirements become a key link.

What are the general requirements for metal cleaning of auto parts?

(1) The cleaning speed is fast, and the dirt on the metal surface can be completely removed within the cleaning time set by the cleaning machine process

(2) Non-corrosive to the cleaning machine and parts to be cleaned

(3) low cost cleaning agent, environmental protection, mild smell

(4) During the cleaning process, no insoluble matter remains on the surface of the cleaning object, no new dirt is generated, no new coating layer harmful to the subsequent process is formed, and the product quality is not affected.

According to the cleaning requirements recommended cleaning agent to meet the process requirements to achieve satisfactory cleaning effect, must be in the cleaning equipment and cleaning methods, cleaning parts material, parts surface dirt type and the next process, water quality, workshop environment to do a comprehensive consideration.

Commonly used metal cleaning equipment includes: 1, immersion cleaning 2, spray cleaning 3, high pressure spray cleaning, 4, ultrasonic cleaning

For immersion cleaning, the components that are generally cleaned are multi-cavity, and the cleaning agent is required to have strong cleaning ability. The requirements for defoaming performance of the cleaning agent are not high, but the cleaning agent is required to have a certain ability to emulsify miscellaneous oil, so as to ensure that the components will not be cleaned after the cleaning agent is taken out and the surface of the components will not be polluted by the miscellaneous oil. The disadvantage of the cleaning agent with strong emulsified oil is that the cleaning ability of the cleaning agent is gradually reduced, resulting in a shorter service life of the cleaning agent.

Most of the cleaning of automobile gearbox parts adopts a through-type spray cleaning machine, which is generally divided into three processes: cleaning-rinsing-drying. Individual processes vary according to process requirements, cleaning-cleaning-rinsing-drying or cleaning-rinsing-rinsing-drying. The spray cleaning machine is equipped with a skimmer, and the use of a cleaning agent with strong anti-miscellaneous oil ability can increase the service life of the cleaning agent. The material of the cleaned gearbox parts is generally forged steel, and the dirt on the surface of the parts is mostly low-viscosity cutting oil. When selecting the cleaning agent, the defoaming ability of the cleaning agent should be considered while considering the cleaning ability. In general, as the temperature of the cleaning agent increases, its decontamination ability also increases, but after a certain temperature is exceeded, the decontamination ability decreases instead, and the most suitable temperature range should be considered when recommending the cleaning agent. On the other hand, because the concentration of the rinsing cleaning agent is generally low, ranging from 0.5 to 1.5, the cleaning agent is required to have a good anti-rust ability.

High-pressure spray cleaning machines are mostly used to remove dirt on the surface of parts while removing metal surface burrs. Positioning and fixed-point spray methods are used for parts. Cleaning agents are required to have good foam resistance under high pressure.
