Caution: Temperature should be controlled in above operation.
5 Coating Process
5.1 Degreasing
The workpiece should be degreased if there is oil on the surface. There are three processing methods:
1.High temperature
2.Neutral water-base degreasing agent
3.Organic solvent such as methylene chloride.
5.2 Derusting
The workpiece can not be coated if there is rust or burr on the surface.The best processing method is shot blasting. The corrosion resistance of coating will be effected if acid cleaning adopted.
5.3 Coating
The workpiece afer degreasing and shot blasting should be coated through Dip-Spin coating or Spraying Coating.
5.4 Pre-heating
The workpiece after coated should be Pre-heated as soon as possible at 80~150℃ for 8~15 mins to evaporate. ( according to heat absorption of workpiece.)
5.5 Curing
The workpiece after pre-heating should be cured at 310-340℃ for 20-40 mins. ( according to heat absorption of workpiece.)
6 Attentions
Other chemicals such as any kinds of acid, alkali salt can not be mixed into coating, for these can activate Zn & Al plate to aging the coating.
Avoid irradiation of sunshine and ultraviolet ray for long time when operating, otherwise it will accelerate aging or polymerization of the coating .
It is very important to control the temperature of coating. If the temperature of coating changes when operating, it will effect the viscosity, then effec the coating quatity on workpiece. So the relations among temperature,viscosity and spinning process shoud be controlled well when coating.
The viscosity will be different if coating method is different. Choose low data if spray coating,and choose high data if dip spin coating.
