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 con
Spraying machine brings a lot of convenience to our work. It is very important to know how to use this equipment correctly. Let us find out what problems should be noticed! 1. According to the size of the work object, the gun heads with different calibers can be used. Generally speaking, the spra
2. What are the advantages of powder spraying?The so-called advantages, of course, will be compared.

(1) high quality cold rolled sheet with thickness less than 1mmNo pinholes will appear after painting. If there is a crack, because there is air in the crack, coating solidification may cause coating interruption and discontinuity, that is, large pores;A porosity is caused by rust or dirt on the sur
The reason for the pinhole in the spray is related to the following points:1. The workpiece has a small amount of water or oil on the surface before spraying. When the temperature is solidified, the oil or water evaporates and vaporizes, leaving pinholes on the workpiece.2. If the pinholes are one p
