In the application process of color coated roll, there are some small problems that we must face. Let’s make a detailed list of the results that will occur.
First, the detailed parts of the color coating roll:
1. Substrate scratch
2. When making veneers, pay attention to the scratch on the back of the product, resulting in color difference, light color on the back, and easy to cause color difference
3. Scratches on spray pipe: main fingerboard with front
4. The guide plate of the inlet section is scratched (main back)
5. Scratches in the curing furnace The objects in the curing furnace are sagging (rare). The swelling force is too large. The front side is scratched, and the tension is too large when the thick material is replaced by the thin material.
6. The exit looper is easy to be scratched (rare) during emergency stop and unloading
7. Scratches on the drying roll. Usually when the drying roll does not rotate
8. The exit section is scratched by foreign matters, and there are foreign matters on the exit guide plate, most of which are scratched on the surface of the color plate by the back or the knife on the scissors
9. The S roll is scratched and the water-cooled squeezing effect is not good. The water is brought into the S roll, and the tension in the furnace is too different from the tension in the outlet loop, which causes the S roll to slip.
10. The initial coating curing furnace plate temperature is not enough, the paint curing is not good, and the back paint is stuck off before water cooling
