Quality process factors of color steel plate

The selection of process conditions also has a great impact on the printing quality. If the coating film is too thin, its smoothness after curing will be poor. On the contrary, because the film is too thick, it will increase the cost and affect the curing of the film. In addition, process conditions such as processing speed, curing time, curing temperature will also affect each other, printing speed (that is, the speed of the printing roller and transfer roller), the coating leveling time is short, and the coating thickness is thick to obtain the same curing effect, curing The time is shorter and the temperature should be higher. Strip absorption is low and should reasonably be conducive to leveling. However, the viscosity of the printing coating should not be too high, otherwise, the shear stress of the coating on the printing surface will increase, which will affect the smoothness of the coating on the surface of the strip, making it difficult to form a continuous film.
