The paint processing method differs depending on the paint used.

In the past painting process, the specific operation process must be combined with the type of paint. Because different paint properties are different, the applicable painting process will be different, which is also the basic requirement to ensure the quality of the paint processing.




Vacuum plating UV coating is more commonly used in chlorinated rubber paint. Although there are many kinds of painting processing methods, it is ideal to brush, spray and roll coating, and it is not suitable to use electrostatic and electrophoretic coating methods. . At the time of painting processing, since such paints dry quickly and have high temperatures, it is necessary to add a high boiling point and an aromatic solvent.




For polyurethane paints, it is also not suitable to use electrostatic and electrophoretic spraying. Before painting, the two-component paint should be added to the curing agent and stirred evenly, so that the paint has a certain activation period and service life, and then sprayed with high pressure and airless. This way a thicker coating can be obtained.




Acrylic paint is also a type of paint currently used. In terms of its characteristics, the spray method is very suitable. After it is evenly stirred, a mixed solvent of a hydrocarbon and an ester is used as a diluent because the film thickness is low. , need to paint several times. There is also a kind of organic polymer paint, which is generally used alone, but when the paint is processed, the paint control drying temperature is at the specified temperature, which is higher than the use temperature; do not sharply heat up during drying, and also prevent the intrusion of dust and foreign matter. Do not mix with other resins.




The spray gun is one of the indispensable equipments in the process of painting. It is used in many industries. The effect of spray processing is related to the reasonable control of the spray gun. Therefore, it is natural to master the number of control methods of the spray gun. Ensure the stability of the spray processing quality.




Generally speaking, the spray gun is controlled by a trigger. The deeper the trigger is, the greater the liquid flow rate. During the spraying of the processing equipment, the trigger is always buckled, not a half buckle. In order to avoid the accumulation of paint sprayed during each spraying process, experienced painters should slightly relax the trigger to reduce the amount of paint.
