What is the relationship between good and bad painting of aluminium panels

Painting is a relatively important process in the manufacture of aluminum panels, and the quality of painting directly affects the decorative effect of aluminum panels. There are four main factors that cause the good or bad coating of aluminium panels, so let us take you through this aspect. Friends who are interested in this area must not miss.

1、Environment

It is required that the interior of the painting room is clean, dust-proof, insect-proof and certain ventilation performance to ensure that the quality of the painted aluminum surface is not polluted. At the same time, the process conditions can be changed in time due to temperature changes.

2、Raw materials

Paint and aluminium plate are the most important factors that can affect the quality of painting in the process of painting, as there are colour differences between batches of paint, insufficient fineness of paint and poor coating rate, poor cooperation between paint and solvent, delamination, etc. will directly affect the effect of painting and produce defects, and the unevenness of aluminium coil substrate, uneven film thickness, poor side deflection, etc. will also directly affect product quality and overall use. Therefore, in the selection of raw materials, should be strictly controlled.

3、Equipment

The coating line requires the coating equipment to be in good condition, the coating equipment requires smooth running, no horizontal or vertical shaking, the coating rollers require fine grinding. All rollers of the coating machine must be controlled within the permissible range, otherwise the surface quality of the coating will be seriously affected.
