Detailed Product Description

 

High Purity Mechanical Zinc Plating , Ratio Metal Protective Coatings

 

1 Mechanical Zinc Plating Information

Trade Name: Zincover

Article/Model No.:JH-9390

 

2 Composition/information on ingredients

JH-9390 is made up of three packs: A,B and C;

 

3 Coating Process

3.1 Mix Ratio

Pack A:16.0 kg

Pack B:24.0 kg (the quantity can be increased appropriately if spray coating)

Pack C:0-50 g (according to different viscosity demand )

3.2

Mixture Method

Before Mixture, Keep weighted A&B into the water bath at 25±2℃ , then stir A to make metal slurry disperse uniformly by frequency mixer ,after A is fully evenly dispersed, reduce the agitating speed to 60r/min, and add B.

3.2.2

Add B to the stirring A slowly. At the moment ,the barrel temperature will go up,when it reaches 35℃, startup refrigerating device to keep the barrel temperature constant at 35℃.

Caution: Temperature should be controlled in above operation.

 

6 Coating Process

 

7.1 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.

 

7.2 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.

 

7.3 Coating

The workpiece afer degreasing and shot blasting should be coated through Dip-Spin coating or Spraying Coating.

 

7.4 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.)

 

7.5 Curing

The workpiece after pre-heating should be cured at 300-340℃ for 20-40 mins. ( according to heat absorption of workpiece.)

 

8 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.

 

9 Packing

 

Pack A:16kg/ Metal BarrelPack B:24KG Plastic BarrelPack C:5.0kg metal barrel

 

10 Quality guarantee period

Before compound 6 months at 20℃

After compound 40 days at 20℃ ( It can be recycled if adding fresh coating continuously. )

It should be stored under 20℃ if not in use.
