Powder coating production technology

Abstract

The invention belongs to the technical field of coating production, in particular to a powder coating production technology. The grinding equipment in the technology comprises an upper shell, a lowershell, a feeding hopper, a grinding roller, a rolling roller, a grinding linear, an outer grinding cylinder, a connecting plate, a stay cord and a swing arm. A driving motor is arranged to drive the swing arm to quickly swing, the swing arm drives the connecting plate to move through the stay cord so as to drive the grinding roller and the rolling roller on the connecting plate to move to grind granular coating on the inner wall of the grinding linear, meanwhile, the breaking effect of the grinding roller is good, and grinding efficiency is improved; the coating which is grinded into small particles falls to the inner wall of the outer grinding cylinder from a No.1 baiting hole on the grinding linear; and the rolling roller on the outer wall of the outer grinding cylinder extrudes the outer grinding cylinder, the outer grinding cylinder deforms, meanwhile, the coating on the inner wall of the outer grinding cylinder is rolled, the rolling roller extrudes the outer grinding cylinder toenable the outer grinding cylinder to deform, and then, the coating is grinded. Since a contact area with the coating is large, grinded coating powder is fine.

Description

technical field [0001] The invention belongs to the technical field of paint production, in particular to a powder paint production process. Background technique [0002] Paint, traditionally called paint in China. The so-called paint is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, oil, or emulsion, with or without adding pigments, fillers, adding The corresponding additives are viscous liquids prepared with organic solvents or water. [0003] Coatings are often in the form of solid particles before use and cannot be used directly, so they usually need to be pulverized. The traditional crushing device has poor crushing effect, and the final crushed particle size often fails to meet the requirements of use. It is also necessary to screen out the paint with a larger particle size for re-crushing, which reduces the production efficiency of the enterprise to ...

AI Technical Summary

Problems solved by technology

The traditional crushing device has poor crushing effect, and the final crushed particle size often fails to meet the requirements of use. It is also necessary to screen out the paint with a larger particle size for re-crushing, which reduces the production efficiency of the enterprise to a certain extent and increases the production cost. ; At the same time, because the raw materials of the coating are not sufficiently ground, it will cause difficulties in the subsequent process of coating grinding, and will affect the quality of the final coating
