Coated aluminium roofing sheet description
The coating process is closely related to the coating quality, and it is required to control the relative linear velocity ratio of coating roller, drawing roller, measuring roller and substrate within a certain range.
According to the different systems and film thickness of coating products, in order to ensure the smooth process of coating, promote the improvement of product quality, coating should set a certain viscosity range.
Coating curing process and oven control must be controlled in accordance with the requirements, do not change at will, otherwise it will seriously affect the color difference and performance of coating products.
