How to make metal plastic coating more textured

How to make metal plastic coating more textured:

Dalian metal plastic coating plastics can basically be painted, but due to the molecular structure characteristics and surface energy of various plastics, it is difficult to choose paint and process. Plastics can be divided into thermosetting and thermoplastic. The former cannot be re molded and used, and the latter can be re produced. Thermal plasticity has a large physical elongation, generally 50% ~ 500%. The force does not change linearly at different elongation.

Paint falling off on plastic surface is mainly caused by insufficient adhesion between substrate and paint. Generally, an effective solution is to spray a layer of adhesive treatment agent developed by Jisheng treatment agent between substrate and paint coating to improve the interlayer adhesion between substrate and paint and solve the phenomenon of paint falling off. The primer used for painting can be phenolic primer, ester rubber primer, nitrate base paint, alkyd primer, etc. among them, alkyd primer has good adhesion and rust prevention performance, and has good bonding performance with nitrovarnish. The primer can be diluted with a matching diluent, pine perfume, turpentine, etc. When spraying, press the handle and spray compressed air from the air outlet to make the paint liquid spray evenly on the object surface from the paint outlet.

Dalian metal plastic primer and painting should be diluted with diluent. Without the measurement of viscometer, diluent can be added according to 100% of the weight of paint liquid, so that the paint liquid can be sprayed smoothly without being too thin or too thick. Alkyd primer can be diluted with pine perfume; Nitro varnish can be diluted with banana water. After high temperature baking, leveling and curing, the powder coating becomes a coating with different effects (different kinds of effects of powder coating); The spraying effect of powder spraying is better than that of spraying process in terms of mechanical strength, adhesion, corrosion resistance and aging resistance, and the cost is also lower than that of spraying with the same effect.

If flower paper is to be pasted on the primer, the primer shall be baked at a slightly lower temperature, 150 ℃ - 160 ℃ constant temperature for 10-20 minutes, non stick to hands and slightly water-resistant, and then pasted with flower paper before finishing treatment. Ceramic coating is sprayed on the metal surface, which has excellent properties such as high hardness, wear resistance, corrosion resistance, good insulation and oxidation resistance. The coating has strong adhesion with the substrate and is not easy to fall off. The ceramic materials sprayed by Beijing naimo technology include alumina, zirconia, chromium oxide, composite ceramic coating, etc.

Dalian metal plastic coating ensures the safety and reliability of the equipment, prolongs the service life, beautifies the appearance and improves the added value. For example, coating a layer of wear-resistant coating on the surface of parts can improve the wear-resistant performance of parts, keep good performance under bad working conditions, and prolong its service life by more than one to two times.
