1) Spray pretreatment equipment for powder coating line
As the shell will contact with pretreatment chemical directly, it should be made of stainless steel AISI 304, thickness :1.2-1.5mm. Bracket does not contact with chemical which will be made of carbon steel, treated by hot hip galvanizing for anit-corrosion purpose.
2) Tanks
Tanks are welded with leak-proof material. The liquid for degreasing and rinsing is neutral or alkaline. So the tanks for degreasing and rinsing stages are made of AISI 304 stainless steel ,thickness 2.5-3.0mm. Phosphating is acidic solution and this Bracket normally does not contact with chemical which will be made of carbon steel treated by hot dip galvanizing for anti-corrosion purpose. Heated tanks are isolated by 50mm rock wool isolation panel
1) Phosphating deposition remove
There is always sediment generated because of the phosphating chemical reaction. The sediment should be removed to avoid nozzles blocked. The deposition tower is put besides the phosphating tank, so that the sediment can be deposited and removed easily. The tower is made of AISI 321 stainless steel , thickness: 2.3-3.0mm
2) pumps
Each tank has its own pump for spraying system. All pumps have mechanical seal and made by tough material, which is durable for chemical. The pumps for degreasing and rinsing stages are standard chemical pumps, the pump for phosphating stage is stainless steel chemical pump.
3) spraying pipes
The main pipe for degreasing and rinsing stage is made of AISI 304 stainless steel . the main pipe for phosphating stage is made of AISI 321 stainless steel . Other sub-pipes are made of UPVC.
4) spray nozzle
Made of UPVC material
5) Exhaust system
Exhaust blower is anti-corrosion type. The exhausting air course is made for 304 stainless steel.
8) heating for chemical tanks
The chemical tanks are heated by oil. The recycle pump adopted is heat water pipe pump. The heat exchanger in the degreasing tank is made of AISI 304 stainless steel. The heat exchanger in the phosphating tank is made of 321 stainless steel.
