With the enhancement of people's environmental awareness and technological progress, water-based cleaning has developed rapidly in recent years. The water-based cleaning agent consists essentially of water, a surfactant, an inorganic compound builder, an antifoaming agent, and the like. The cleaning process is: degreasing, water rinsing, deionized water rinsing, rust prevention, and drying. The biggest difference between water-based cleaning and solvent cleaning is rust-proof drying after cleaning. After cleaning with organic solvent, the parts will not corrode and rust, and it is easy to use. After water-based cleaning, the metal material will corrode and rust during the evaporation process, that is, the use of high-purity deionized water rinsing can not achieve the purpose of not rusting. Therefore, when using water-based cleaning agent, it is necessary to use rust-proof rust-proof oil or water agent rust inhibitor to prevent rust.
The use of dehydrated anti-rust oil or water-soluble anti-rust agent in mechanical manufacturing has a good anti-rust effect. However, in the refrigeration industry, compressors, condensers, and evaporators must be combined to ensure that refrigerators and air conditioners are free of repairs in fully enclosed systems in 1015. In the past, organic solvent cleaning and chromate passivation were used. This process has good effect on cleaning and rust prevention of parts. Long-term use proves that the process is safe and reliable. Since there are several water rinses in the water-based cleaning process, as long as the agent that affects the current R134a refrigerant and the refrigeration oil is used less, the key is the selection of the water agent rust inhibitor in the water-based cleaning agent. Due to the harsh operating conditions in the refrigeration system, the introduction of a small amount of rust inhibitor can complicate the chemical reaction of the refrigeration system. In a type of HCFC refrigeration system, due to the dissociation of chloride ions and the decomposition of rust inhibitors, the deterioration of lubricating oil and carbonation will be accelerated, which will affect the service life of refrigerators and air conditioners.
