Printed color steel plate is widely used in construction industry because of its good corrosion resistance and various colors. And the performance of the plate will also be affected by the thickness, so when we choose the product, we should carefully
observe its thickness, so what are the influencing factors for the thickness? Please see the analysis in this paper.
1. Pressure between rolls refers to the pressure between the material lifting roll and the coating roll. The higher the pressure is, the lower the coating film is.
2. Cycle speed ratio - within the specified range, the higher the cycle speed ratio
is, the more paint will be applied to the steel strip. However, when the speed of the production line is reduced, the rotation speed of the coating roller will decrease with the decrease of the line speed, resulting in thin film.
3. Roll diameter
- the larger the roll diameter is, the thicker the film is under the same circumferential speed ratio.
4. Viscosity - high viscosity and thick film. In the actual production process of printing color steel plate, with the change of season, the rise
and fall of temperature will also affect the viscosity.
The above are several common factors affecting the film thickness of printed color steel plate. Different factors will lead to the change of film thickness, so in the process of purchasing,
we should pay attention to the production process of manufacturers, and choose the plate products produced by regular manufacturers, so as to ensure that the performance and beauty of the plate meet the requirements.
