Dispersion Coating Overview:

The processing method of dispersion coating is to uniformly distribute the coating material in the solvent to form a dispersed liquid (solid material mixed in the liquid). This mixture is atomized by high-pressure air and sprayed on the surface of the workpiece.

Preparation of the workpiece
In order to obtain sufficient surface adhesion on the surface of the workpiece, all grease must first be removed from the surface to be coated. We dissolve the oil with an organic solvent and heat it to about 400°C to make it completely volatile. In the next step, the workpiece is cleaned and the surface is rough by sandblasting. The use of an adhesive (primer) can improve the binding ability of the coating to the surface of the workpiece.

Powder spraying

The powder particles are blown out of the collector by compressed air, and there is an electrostatic zone on the way to the spray gun nozzle. Because the particles carry the same charge, they repel each other in the flight path, forming a uniform cloud. The workpiece to be sprayed is ground so that an electrostatic zone is formed between the spray gun and the workpiece. The powder particles are attracted to and adhere to the workpiece.

powder melting

In coating technology, high-temperature spraying and low-temperature spraying are different in principle. If high temperature spraying is used, the temperature of the substrate is higher than the melting temperature of the powder material, and the powder particles are coated on it. The micropowder thus melts during spraying.

In order to obtain sufficient surface adhesion on the surface of the workpiece, all grease must first be removed from the surface to be coated. We use an organic solvent to dissolve the grease and warm it to about 400°C to completely volatilize it. Next, the workpiece is mechanically cleaned and roughened by sandblasting. The bonding ability of the coating to the surface of the workpiece can be improved by applying an adhesion aid (primer).
