With the rapid development of China's automobile industry, the market demand has great potential for development. In the manufacturing process of auto parts, the maintenance and cleaning of metal parts of machinery and equipment is a very important stage. Along with the development trend of industrial production cleaning technology, and everyone's awareness of environmental protection, everyone on the application ofCleaning agentAnd cleaning machinery and equipment are clearly put forward higher regulations.

(I) environmental protection metal material partsCleaning agentGeneral provisions

First, the cleaning machinery and equipment and the parts to be cleaned are not easy to be eroded. Second, the whole cleaning process is not easy to cause residues, including insoluble substances, wastes and soil layers that are unfavorable for subsequent production and processing. The following is the cleaning efficiency is high, and the cleaning is sufficient and complete. In the end, it also needs low cost, in line with the regulations of ecological environment protection, no harm to the body, and the taste also needs to be relatively soft.

In the field of laser cutting and processing of metal materials, with the increasing number of regulations that everyone can't see the characteristics of zero and the high efficiency of production and processing, the cleaning agent is no longer a simple decontamination effect, but has been granted a large number of regulations. According to the characteristics of metal composite materials, the applicationCleaning agentAt the same time, it is necessary to have anti-rust treatment effect on the surface of metal parts and improve the corrosion resistance of goods, which clearly puts forward higher provisions for the modifier added to the cleaning agent.

Classification and analysis of (II) cleaning machinery and equipmentCleaning agentProvisions

At this stage, common metal material cleaning machines and equipment include immersion cleaning machines and equipment, self-spraying cleaning machines and equipment, high-pressure self-spraying cleaning machines and equipment and ultrasonic cleaning machines and equipment.

Intrusion cleaning is generally used for multi-cavity parts, which has high requirements for the cleaning ability of cleaning agents and the ability of emulsion miscellaneous oil, but not for demulsification characteristics. However, the cleaning agent with strong emulsion oil capacity has a defect, the cleaning capacity will gradually decrease, so the service life is short.

When cleaning the parts in the automobile transmission, most of them choose the self-spraying cleaning method according to the type. After cleaning, it is necessary to carry out immersion and drying treatment. Self-spraying cleaning machines and equipment are generally equipped with oil skimmers, and suitable cleaning agents with strong anti-miscellaneous oil ability are selected. In addition, demulsification ability needs to be considered. Cleaning agent has its own best application temperature range, its cleaning ability is increased with the temperature rise, but once it exceeds this category, the cleaning ability will be reduced. Therefore, it is also important to grasp the appropriate cleaning temperature.

High-pressure self-spraying cleaning is mostly used to remove waste on the surface of parts and components. At the same time, it is also necessary to remove burrs on the surface of metal materials. Accurate positioning and designated self-spraying methods are mostly used for parts. It is stipulated that the cleaning agent has very good resistance to foam under high pressure.

Regulations on cleaning agents in (III) post-production and processing procedures

Under some special processing technology standards, the selectionCleaning agentIt is also important to take into account the hazards to the subsequent production and processing processes. For example, in the case of manufacturing transmission gear parts, the process that must be machined includes two steps of grinding teeth and shot blasting. These two processes must be carried out after the transmission gear self-spray cleaning. Then, when cleaning in the middle between grinding teeth and shot blasting, it is important to take into account the appliedCleaning agentWhether it will cause harm to the shot blasting process behind, such as whether there will be sticky on the surface of the part after drying treatment.Cleaning agentResidual or masking film, etc. This will destroy the production and processing quality of the shot blasting process, resulting in the shortcomings of the goods.
