As a professional coating plate manufacturer, the most common process is: uncoiler - sewing machine - roller - expander - uncoiler looper - alkali elution - grease - Cleaning - drying - passivation - drying - first coating - finishing coat - finishing
coat drying - air cooling - coiling looper - coiler - (lower roll is packed and put into storage). Here are the details
Uncoiler: its task is to serve as the bottom plate of uncoiler, and stably transport according to the frequency of frequency
conversion. Sewing machine: first of all, it adopts Street sewing to ensure the smooth production. Stretcher: This is a useful stretching system. The tensile force comes from the speed difference of the production line. Its function is to ensure the smooth
operation of the steel plate without supporting the furnace bottom and prevent the steel plate from scratching. The tension directly affects the winding quality.
Ring opening: the role of ring opening is to ensure that the strip steel produced is
continuous, because the solid strip steel of looper ensures that the strip steel has enough production time. It is to clean the oil and impurities on the base plate, ensure the cleanness of the plate surface, and lay the foundation for the later coating
Cleaning: after degreasing, clean the residual liquid on the plate with clear water to ensure there is no residual liquid, so as to prepare for future product quality operation. Color coated plates are widely used. It has the characteristics
of no pollution, good weather resistance, corrosion resistance and high processing.
