Abstract

A process for modifying the surface of superfine paint particle in order to improve the flowability of paint particles for airflow delivery features that the airflow or external mechanical force is used to make small and hard additive particles collide or squeeze with paint particles. Part of additive particles is anchored on the surface of paint particle and other additive particle is adsorbed by its exposed rest. Its advantages are high effect, low cost, and simple operation.

Description

Technical field

[0001] The invention relates to the field of powder coating on metal and non-metal surfaces, in particular a technical invention that uses nanometer and micron materials to carry out surface modification treatment on ultrafine paint powder particles so as to realize ultrafine paint powder coating. The present invention can also be applied to other technical fields involving ultrafine powder operation. Background technique

[0002] The surface spraying of metal products can be divided into the traditional "wet paint spraying process" and the new "powder paint spraying process" according to the spraying process. Although wet paint spraying has a thin, uniform paint film and a high surface finish. However, because it uses organic solvents as dispersants and diluents, the toxic organic solvents volatilized after spraying cause great harm to the environment. Some of these solvents also have a strong destructive effect on the ozone layer. On the other hand, the ...
