Revestimento em pó metálico

Surface Finish Options Overview

Based on the users’ pursuit of metal texture and effect, the market demand for metal powder is increasing. At present, the market mainly relies on paint with metal effect, which has high cost, soft coating hardness, low utilization rate, and the VOC emission of paint seriously pollutes the earth’s ecological environment and affects human health. With the continuous advancement of the national green development policy, environmental protection laws and regulations have been implemented in various places, and the wave of ”painting powder” has become a general trend.

Definição e classificação de pó metálico

Revestimento em pó com efeito metálico, em termos simples, é uma variedade de revestimentos em pó baseados em pó comum, por meio de um processo de mistura, mais pigmentos metálicos (como: pó de alumínio prateado, pó de mica e pó de ouro cobre, etc.), que podem apresentar um efeito decorativo brilhante e luxuoso.

Princípio de ligação de pó metálico

The bonding technology of powder coatings and metallic pigments appeared in 1980, when a pigment company first launched this bonding process in continental Europe. Subsequently, European powder coating companies took the lead in successfully applying thermal bonding technology to the production of powder coatings.

Powder coating bonding technology is also called thermal bonding technology. It mainly uses friction heating or jacket heating to make the surface of powder particles have a certain viscosity, so that the metal effect pigment and the powder base powder are combined. Specifically, the bonding machine’ s stirring paddle rotates at high speed, so that the powders and the metal effect pigments, the powders and the bonding machine (stirring paddle, cylinder wall) collide and rub at high speed. Within a certain period of time, the surface temperature of the powder particles rises to a certain degree, the powder surface softens, and the metal effect pigment particles and the powder coating particles are bonded together.
