Studies of Chemical Adsorption Membrane in the Steel Surface on Application

Article Preview

Abstract:

In this study we selected polyethylene glycol (400), triethanolamine, silane coupling agent and glycerol as the main raw material, and systematically studied the chemical adsorption film technology on the steel surface by taking one step. Under the optimum conditions ( polyethylene glycol (400) was 10mL/L, triethanolamine was 40mL/L, silane coupling agent was 10mL/L, glycerin was 15mL/L, the pH was 10, the time was 12min, and temperature was 45°C), we characterized the chemical adsorption film by SEM, XPS and IR. The results showed that the treatment process was simple, the tank liquor was stable, the chemical adsorption film was dense, uniform. This adsorption membrane resistance to corrosion and coating adhesion was superior to the traditional phosphating process.
