Metal cleaning agents and metal cutting fluids are used in different stages of machining. Metal cleaning agents are an indispensable quality control process before the product is delivered, sealed and oiled to ensure the cleanliness of metal workpieces, high assembly accuracy and long sealing and rust prevention period. In the process of cleaning metal workpieces, water-based cleaning fluids and rinsing water are frequently replaced to ensure the cleanliness of the workpieces. If these waste liquids are not well treated and utilized, arbitrary discharge will cause pollution to the environment. Metal cutting fluids are important supporting materials for mechanical processing. They mainly play four roles in cooling, lubricating, cleaning and rust prevention in mechanical processing, ensuring the surface finish and processing accuracy of the metal cutting process.
