It is not difficult to find that many configurations will use spray paint this way to extend the use of products. Especially in the manufacturing industry and the mold industry, when the staff in the process of use will adopt some technologies to strengthen the use of equipment. The working area structure of the manufacturing industry involves plastic toys. Plastic toys are painted to enhance their characteristics before mass production. Therefore, the staff of plastic toy manufacturers know that spray painting is a kind of help to increase the use of product attributes.            Spray painting is essentially a technique.            The process of painting plastic toys can obtain a variety of properties at the same time, that is, wear resistance, corrosion resistance, heat insulation, conductivity, insulation, sealing, lubrication and other special mechanical physical and chemical properties of the coating. Corrosion resistance: The ability of metal materials to resist the corrosive action of surrounding media is known as corrosion resistance. It is determined by the composition, chemical properties and structure of the material. Chromium, nickel, aluminum and titanium, which can form protective film, are added to steel. Corrosion resistance can be improved by changing the electrode potential of copper and improving the intergranular corrosion of titanium, niobium, etc. Under the action of strong electricity, the insulating material may be broken down and lose its insulating properties. In the above three insulating substances, gas insulating substances after breakdown, once the removal of external factors (strong electric field) can recover its inherent electrical insulation performance; After the breakdown of solid insulating material, it will irreversibly completely lose its electrical insulation performance. Therefore, the insulation selection of electrical lines and equipment must be matched with the voltage level, and must be adapted to the use of the environment and operating conditions, in order to ensure the safety of insulation. In addition, due to corrosive gases, vapors, moisture, conductive dust and mechanical operation, the insulation performance of insulating materials may be reduced or even destroyed. Moreover, the long-term effect of sunlight, wind and rain and other environmental factors can also make the insulation material aging and gradually lose its insulation performance.
