Through comparison, it is found that the original steel barrel coating production line is all developed with water curtain spray paint. While the trough which often contacts with water and other materials are stainless steel, which is the only way to meet the demand of water-based paint for materials. However, in the future, the corrosion of waterborne paint on other parts should be effectively avoided. Corrosion prevention treatment should be carried out in the functional area and the wall panel of the spray-painting room, so as to ensure the smooth development of the follow-up work. Such as in the production line planning and design, in the case of investment conditions allow the use of stainless steel materials as far as possible, such as financial constraints then it is necessary to carry out anti-corrosion treatment.
