Description

This device is a major technological innovations by our company, and  a revolutionary new process for surface treatment of cold-rolled steel door panel products. Applicable to thickness range of 0.**2.5mm of cold-rolled steel door panel, with design of complete program control to achieve a fast processing of degreasing, roughening, inactivating and drying off cold-rolled steel sheet, which occupies less space than traditional phosphate process equipment. The adhesion of coated layer has been greatly enforced which is suitable for the successive mechanized re-processing, stabilizing the surface treatment quality, lowering operation costs, and pollutant emissions qualified. Either a steel coil can be processed continuously or a single door panel can be processed one by one.
Working principle:
The steel sheet metalwork need to be pretreated immersed in the chemical solution while two groups rolling stainless steel hairbrushes rotating to clean the surface of the metalwork continuously, and one or two group nylon hairbrushes rotating while clean water add to the surface of the metalwork, and finally the metalwork will be dried off by industrial fan. 
Parameters:
1. Outside dimensions: L****0×W***0mm.
2. Processible steel panel dimensions: δ=0.**2.5mm，W≤***0mm.
3. Production capacity: For example of δ=0.7mm, L***0×W***0mm steel panel approx. **0 pieces per hour.
Remarks:
We can tailor made for your specific requirements.
