The manufacturer of Equipment for the production of powder coatings tells you that you often encounter various problems in the construction of powder coatings. Let's take you to find out in detail.

customized Equipment for the production of powder coatings price(s) china
1. Quality problems of the raw material itself: If the relative molecular mass distribution of the same kind of polyester from the manufacturer of Equipment for the production of powder coatings is very wide, the curing speed is significantly different, and the curing speed cannot be fully flowed, and the curing speed is slow, and it is difficult to be cured. The parts are leveled, causing the parts with fast curing speed to become shrinkage holes. Equipment for the production of powder coatings manufacturers have a high content of low-molecular-weight resins, and larger pores are likely to occur when the coating is slightly thicker. Low-cost raw materials are used in the synthesis of polyester resin, which has poor anti-interference ability.
2. Poor miscibility and mismatch of materials: Equipment for the production of powder coatings manufacturer's leveling agent can sometimes have a better leveling effect on a certain polyester, but it is difficult to have a leveling effect on another polyester; it is moist and bright. The agent can sometimes promote leveling, eliminate shrinkage, and sometimes have a negative effect. Therefore, it is important to conduct material matching tests in advance when formulating the formulation.
3. Active fillers: Some fillers of Equipment for the production of powder coatings manufacturers are treated with surfactants, and some surfactants are more likely to cause reverse ionization during electrostatic spraying, which may cause the deposited powder coating to break down and cause Dimples and shrinkage holes. In view of this phenomenon, lower voltage spraying should be used to eliminate the influence caused by reverse ionization.
4. The impact of production equipment: Equipment for the production of powder coatings manufacturer's feeder leaks oil, extruder partially seeps water, ACM grinding center bearing temperature is too high, lubricating oil volatilizes, once the material seeps with oil, it will cause coating defects The root cause.
