    The pre-treatment of painting includes three parts: degreasing, rust removal, and coating (phosphating and non-phosphorus conversion)


    Coating (phosphating, phosphorus-free conversion) is an important part of the center.


    The high-quality film (phosphating, non-phosphorus conversion) is only formed on the surface of the workpiece from which foreign matter such as oil, rust, and oxide scale has been completely removed


    Degreasing and rust removal are the two basic processes before the coating (phosphating and phosphorus-free conversion).


    With the development of industry, environmental protection and improvement of working conditions have become issues of common concern


    Especially worthy of attention is the suppression of acid mist.
