Pre-treatment processing
Pre-treatment processing refers to a set of processing including
alkali washing &derosination, weak acid surface adjusting,
phosphating &film and washing spray that carried out to the
base at the end of metal processing but before electrostatic spray.
Derosination--It is a saponification reaction of alkaline metal
absorbent and Stearic acid in the metallic surface oil, which forms
Sodium stearate and glycerol. Grease is fully dissolved in alkaline
solution, this can remove oil.
Surface adjusting--To change the microscopic state of the metal
workpiece surface to prepare for phosphorization. The surface of
the workpiece adsorbs a large number of crystal nucleation and
phosphating growth points in a short time and low temperature, so
that the surface activity of the workpiece is homogenized.
Phosphorization--To protect matrix metal,preventing metal corrosion
in a certain extent; to be used as priming before spry,improving
the adhesion and corrosion resistance of the coating layer; In the
market, many manufacturers use the passivated of raw materials,
without any pre-processing, they are sprayed immediately after
metal processing, resulting in poor adhesion between the coating
layers and the base surface. After using more than 1year, the
powder and coating will drop out.
