What is the solution to the poor defoaming performance of the curtain coater? The UV coating formulation is improper or the storage temperature is too high, the storage time is too long, and the ultraviolet light will leak. The following points:
Rain coating machine
1. Choose UV topcoat with good defoaming properties.
2, a filling back cover should be fully sealed, and no small gaps should be left.
3. Try to avoid working under high temperature for paint, curing machine and leveling machine, which will cause the substrate temperature to be too high (not exceeding 60℃), which will cause the air to expand and escape.
4. It is recommended to use a new type of scratch putty to fill before a primer.
5. Keep a distance of about 10cm between the shower head and the workbench.
6. Reduce the distance between the coating head and the work, and reduce the height difference between the oil tank outlet and the paint bucket.
