After disassembling the hydraulic punching machine, it can be cleaned with cleaning solution. Common cleaning solutions include organic solvents, alkaline solutions, and chemical cleaning solutions. There are manual and mechanical cleaning methods for cleaning. The punching machine will provide a detailed introduction to the functions of these cleaning fluids.

Organic solvents

Common ones include kerosene, light diesel, gasoline, acetone, alcohol, and trichloroethylene. Organic solvent degreasing is based on the dissolution of pollutants, which is non-destructive to metals. It can dissolve various types of oils and fats, does not require heating, is easy to use, and has a good cleaning effect. However, most organic solvents are flammable and costly, making them primarily suitable for small units and loose repair operations.

Alkaline solution

It is an aqueous solution of alkali or alkaline salt. By using alkaline solution and saponifiable oil on the surface of the parts, a chemical reaction is carried out to generate easily soluble soap and glycerol that does not easily float on the surface of the parts. Then, by flushing with hot water, the oil can be easily removed. For situations where non saponifiable oil and saponifiable oil are difficult to remove, emulsifiers should be added to the cleaning solution to separate the oil stains from the surface of the parts after emulsification. Common emulsifiers include soap, sodium silicate, bone glue, tree resin, etc. Different cleaning solutions should be used to clean parts with different materials. Alkaline solutions have varying degrees of corrosive effects on metals, especially on aluminum.

Chemical cleaning solution

This is a chemically synthesized water-based metal cleaning agent, mainly composed of surfactants. Due to the decrease in interfacial tension caused by its surfactants, it exhibits various effects such as wetting, soaking, emulsification, and loosening, and has strong cleaning ability. It also has non-toxic, non corrosive, non combustible, non explosive, and pollution-free properties, with certain rust prevention ability and lower cost benefits. It has gradually replaced other cleaning fluids.
