1、 Product performance
Cleaning pre film agentIt is mainly composed of phosphonates and active compounds. This product forms a deposition film on the metal surface by chelating with calcium and magnesium ions in cooling water, which adheres to the metal surface. This type of membrane has high resistance and can isolate metal from corrosive media in water, thereby inhibiting corrosion.This productIt has the characteristics of fast film formation speed, fine and uniform film quality, good chemical stability, and low corrosion rate.
