Dacromet anti-corrosion coating characteristics

 

1.1 anti-corrosion mechanism Dacromet coating, the appearance of matte silver gray, from the very fine sheet metal zinc, aluminum and chromate and other ingredients. After the workpiece in the degreasing, shot blasting treatment, dip Tu Duo Luo liquid.

Dacromet liquid is a water-based treatment solution, metal parts in the water-based treatment solution dip or spray, and then into the furnace curing, about 300 ℃ baking film, and the formation of zinc, aluminum, chromium inorganic coating Floor.

 

2. Coating Process

 

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 )

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℃.

5. Coating Process

 

Low Form Dip Spin Coating / High Dipping Speed Electroplated Zinc Coating

 

6.1 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.

 

6.2 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.

 

6.3 Coating

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

 

6.4 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.)

 

6.5 Curing

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