The purpose of cleaning hardware parts is to remove surface stains. Different cleaning fluids need to be selected according to the cleaning object. There are two types of cleaning fluids: water-based cleaning fluid and solvent-based cleaning fluid. Hydrocarbon hardware cleaning agent has a good effect of removing oil and grease, and has a corrosion inhibitor effect on metals such as steel. When cleaning, it has no corrosion to equipment, copper, stainless steel and other components of different materials, and the operation is simple, safe and reliable.
The main methods of degreasing and degreasing of hardware and metal are: organic solvent method, chemical method, electrochemical method, and water-based cleaning agent cleaning method. The commonly used organic solvent trichloroethylene cannot completely remove the polishing wax, especially the metal on the surface of the metal. Oxides, carbides, and abrasives cannot be effectively cleaned away; not only is trichloroethylene more toxic, it has a tendency to hydrolyze improperly, and is corrosive to metals under wet conditions.
The ultrasonic cleaning process of hardware parts is the interaction between the cleaning medium, pollutants, and the appearance of the parts. It is a complex physical and chemical process. The purpose is to make the appearance of the metal stamping parts reach a certain clean level after ultrasonic cleaning.
