Does Plastic Balls Wholesaler explain the influence of the POM plastic ball surface finish on the sealing effect?
The POM plastic ball is used as a sealing ball. Its function is like the principle of a ball valve. It is mainly sealed by a spherical surface, but the sealing effect is mainly related to the precision and surface finish of the POM plastic ball. Generally speaking, the smoother the surface, The better the sealing effect.
The POM plastic ball has the characteristics of good precision, high hardness, non-absorption, and oil resistance. In addition, when the surface polishing reaches the nanometer level, the POM plastic ball has the characteristics of non-stick contaminants, and the sealing effect will always be good. If the surface polishing effect Poor, then if the liquid in the pipe is dirty, the surface of the POM plastic ball may be stained with dirt, which will affect the sealing effect of the POM plastic ball. Therefore, if the POM plastic ball has a good sealing effect, it must be polished to the nanometer level. Finish.
