Considering from the powder coating, if the matching between the resin and the curing agent is unreasonable in the formulation design, for example, the reactivity selection of the resin or the selection of the type and amount of the curing agent is unreasonable; the mass percentage or the volume concentration of the filler is too large, etc. Will affect the physical and mechanical properties of the film.
First, the effect of coating ambient temperature and temperature on the film thickness. The powder spray amount is 170-200 g/min; the voltage is 70 KV, and the distance between the spray gun and the object to be coated is 20 cm. When the temperature is between 20 and 30 ° C and the humidity is between 60 and 80%.
Three important stages for good powder coating process.+86 13363836725
Electrostatic spray is a commonly used spray method. The surface of the workpiece sprayed with electrostatic spray is smooth, the coating is thick, and the defects of particles are not easy to occur. Moreover, the adhesion of the surface coating film is good, and the corrosion resistance and weather
The first step in the production of carefully patience, the products produced on the coating line are for the sake of beauty and durability, and must be carefully produced. Let's talk about the factors that make the coating surface rough.
The powder coating uses powder coating, and the process uses electrostatic spraying. Under the influence of the accelerating wind, the powder particles are sprayed out of the gun body and carry a positive charge, which is in contact with the negatively charged profile. Electrostatically adsorbed and
Properly increasing the powder coating thickness can effectively reduce the formation of particles.

Reciprocators use a variety of electronics to control both stroke and speed. In these machines, the mechanical linkage between the motor and guns is fixed; therefore, speed and stroke control must be adjusted electrically. These adjustments are sometimes made at the control panel or at the units itself.
