What should I do if the plastic powder shrinks during use?

Plastic powder is a widely used product with a high demand in daily life. However, users who have used it may also find some problems. When using plastic powder, we sometimes notice shrinkage problems. So, how should we deal with such problems? Now let's talk about this type of problem with everyone.

How to deal with shrinkage of plastic powder

Constituent factors:

The pre-treatment degreasing is not careful and complete, leaving oil stains on the surface. Perhaps the shrinkage caused by the residual active agent on the surface after degreasing cannot be cleaned thoroughly by water washing. The compressed air used for electrostatic spraying of plastic powder exceeds the target oil and water content, resulting in contamination of the plastic powder. During the spraying process, solvents containing volatile silicone oil are used around. The oil stains on the suspension chain are blown down by air conditioning to form shrinkage holes on the plastic powder.

Solution:

Improve the temperature of plastic powder pretreatment, extend the pretreatment time, or modify the hanging method, change the spray angle of the nozzle to achieve a clean and neat result; Replace with more suitable and useful degreasers, as each degreaser has a corresponding type of workpiece. Control the concentration and proportion of the pre degreasing tank and degreasing tank solution, reduce the amount of oil carried by the workpiece, and enhance the water washing effect to improve the surface phosphating film.
