The fastener can appear sometimes phosphating phenomenon, how to deal with the touch fasteners phosphating?
Fasteners surface yellowing, the reason may be caused by low concentration, low temperature phosphating accelerant situation. Processing method is adding accelerator, improve the phosphating temperature.
Fasteners surface covered with a layer of crystalline, probably because the temperature is too low or too low and cause the free acidity. Removal of this layer of crystal way is adding phosphate or lower temperature.
Fastener Cao bath sediment because of phosphating time too long, accelerator concentration caused by too much. The solution is to shorten phosphating time, concentration of reducing natural.
The way to solve the problems.
