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

 


Pack A: It is silver gray slurry that mainly chemically combined with super fine flake Zn, super fine flake Al and ethylene glycol. The radius-thickness ratio of Zn plate is 60~100.

Pack B: It is the solvent of the coating colored in orange-red and in water solution, which contain the Cr6+.

Pack C: It is the tackifier of the coating which mainly made up of cellulose white or yellowish powder.

Coating Process:
 

 


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 )
 

 


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.

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℃.
 

 


3. Stir the mixture about 1~2 hours fast after B added, then add C. C should be powdered if lump exist.(The barrel temperature should not be lower than 30℃, otherwise C will not be dissolved sufficiently .)Then stir 12 hours continuously.
 

 


4. The coating should be filtrated by 80~100 mesh stainless steel screen before pouring into dip barrel.
 

 


5. Temperature control device should be equipped with dip barrel to keep the temperature of coating at 22±2℃.

(If temp. is too high, the paint is liable to deteriorate, and viscosity will be effected.) The coating should be stirred circularly to keep evenly dispersed.
 

 


6. Test density, PH, Temperature, Viscosity and Cr6+ content of coating every 8 hours if operate continuously.
