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, the selection of paint and the difficulty of the process are different. Plastics can be divided into thermosetting and thermoplastic. The former cannot be reshaped for use, while the latter can be re produced. The physical elongation of thermal plasticity is relatively large, generally 50%~500%. The force does not change linearly at different elongation.

The paint peeling off of plastic surface is mainly caused by the insufficient adhesion between the substrate and the paint. Usually, the effective solution is to improve the adhesion between the substrate and the paint by spraying a layer of adhesion treatment agent developed by Jiongsheng treatment agent between the substrate and the paint coating, so as to solve the paint peeling phenomenon. Primers for painting can be phenolic primer, ester adhesive primer, nitrocellulose base paint, alkyd primer, etc. Among them, alkyd primer has good adhesion and rust resistance, and has good bonding performance with nitrocellulose varnish. The primer can be diluted with matching diluent or pine perfume, turpentine, etc. When spraying, press the handle and spray compressed air from the air outlet nozzle, so that the paint liquid is evenly sprayed on the object surface from the paint outlet nozzle.

Dalian metal plastic coating primer and spray paint shall be thinned with thinner when used. In the absence of viscometer measurement, thinner can be added according to 100% of the weight of the paint liquid to ensure that the paint liquid can be sprayed smoothly, not too thin or too thick. Alkyd primer can be diluted with pine perfume; Nitrocellulose varnish can be diluted with banana water. The powder coating becomes a coating with different effects (different kinds of effects of powder coating) after being baked and leveled at high temperature; The spraying effect of powder spraying is superior to the painting process in terms of mechanical strength, adhesion, corrosion resistance, aging resistance, etc., and the cost is also under the same effect of painting.

If decal paper is to be pasted on the primer, the primer should be baked at a slightly lower temperature, with a constant temperature of 150 ° C - 160 ° C for 10-20 minutes. It is not sticky and slightly water resistant. Then, the decal paper should be pasted and the finish paint should be applied. Spraying ceramic coating on metal surface has high hardness, wear resistance, corrosion resistance, good insulation, oxidation resistance and other excellent properties. The coating has strong adhesion with the substrate and is not easy to fall off. The ceramic materials sprayed by Beijing Nemo Technology include aluminum oxide, zirconia, chromium oxide, composite ceramic coatings, 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 part surface can improve the wear-resistant performance of the part, enable it to maintain good performance under bad working conditions, and extend its service life by more than one to two times.
