The difference between plastic spraying and spray painting

The difference between plastic spraying and painting lies in cost and durability. Different costs: Generally speaking, plastic spraying costs more than painting. The reason is that plastic spraying adopts powder spraying technology, which requires many processes such as baking, raw material preparation, cleaning and rust prevention. This requires more manpower and relatively high time and material costs. Spray painting can be done at one time, which is relatively simple, and the paint used will be cheaper than plastic spraying. Durability is different: plastic spraying can form a tough protective layer on the surface of the object, thus playing an anti-corrosion role and prolonging the service life of the object. The strength of plastic spraying coating is high, which can increase the hardness and wear resistance of the surface of the object, thus reducing wear. So the service life is much longer. The color and surface effect of spray painting are more delicate and beautiful, but its durability and protective effect are worse than that of plastic spraying. Cold sprayed zinc is a new type of heavy-duty anti-corrosion material for steel structures, which is mainly composed of inorganic siloxane resin and high-purity imported zinc. It has excellent weather resistance and corrosion resistance, and is the most promising high-performance anticorrosive coating. If we strictly follow the specific requirements of construction and strengthen construction management, not only the construction efficiency is high, but also the best protection effect can be achieved by cold spraying zinc. Hot spraying zinc: using oxygen, acetylene or electric heating source (large workpieces are heated by electric heating, small and medium-sized workpieces are heated by oxygen and acetylene), spraying zinc on the metal surface at ultra-high speed through compressed air and special tools (spray guns).
