Abstract

The invention discloses a spraying process of flash powder, which sequentially comprises the following steps: A, carrying out primary spraying; B, sticking the flash powder; C, shaking off; D, keeping standing; E, carrying out secondary spraying; F, carrying out primary baking; G, carrying out tertiary spraying; and H, carrying out secondary baking. The spraying process of the invention has the advantages of effectively improving the adhesion efficiency of the flash powder, improving the surface uniformity of the product, saving the dosage of the flash powder, achieving no waste and effectively saving cost, thus the flash layer on the surface of the product is firm and not easy to drop off; and the flash powder does not need to be sprayed on the surface of the product through a spray gun, thus avoiding clogging a nozzle.

Description

technical field [0001] The invention relates to a flash powder spraying process. Background technique [0002] In order to make the surface of the metal product more attractive in appearance and protection, a layer of flash powder will be coated on the surface of the metal product. The existing technology is to mix the flash powder in the paint and spray it on the surface of the metal product with a spray gun. When blending into the paint, because the specific gravity of the glitter powder is too heavy and the particles are large, the glitter powder will sink to the bottom of the paint, and it is easy to make the glitter powder on the surface of the product uneven when spraying, and the larger particles of glitter powder are also easy to block the spray gun Nozzles reduce production efficiency. Contents of the invention [0003] The object of the present invention is to provide a flash powder spraying process, which can effectively solve the existing problems that the fla...
