Introduction
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.
Standard has accumulated more than ten years of technology and has continuously cooperated with advanced equipment suppliers and material suppliers at home and abroad. The bonding technology metal powder coating provided by Standard can provide users with solutions to replace paint. It is a green and environmentally friendly product that can achieve sustainable development of human beings and the environment.
Definition and classification of metal powder
Metallic effect powder coating, in simple terms, is a variety of powder coatings based on ordinary powder, through a mixing process, plus metal pigments (such as: silver aluminum powder, mica powder and copper gold powder, etc.), which can show a bright and luxurious decorative effect.
Metal powder bonding principle
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.
