Process Conditions And Key Parameter Management Of Plastic Electroplating-electrophoretic Coating.

Process conditions and key parameter management of plastic electroplating-electrophoretic coating.
Huizhou Boluo Tenglong Technology Co., Ltd. serves you wholeheartedly! Mainly engaged in plastic hydroelectroplating processing, with plastic injection molding processing, mold processing and so on!
The process conditions of electrophoretic coating include the following four aspects and 13 conditions (parameters):
1) the composition of the bath solution: solid, ash, MEQ and organic solvent content.
2) Electrophoretic conditions: bath temperature, electrophoretic voltage and electrophoretic time.
3) characteristics of bath solution: ph value and electrical conductivity.
4) Electrophoretic characteristics: curing efficiency, maximum current, film thickness and electrophoretic penetration.
Among them, the voltage and time of swimming coating, solid content of bath liquid, temperature, PH value and electrical conductivity are the main items of field control and management.
