The characteristics of multi-arc ion plating coating for vacuum coating machine in plastic industry

Compared with the evaporative coating machine and the sputter coating machine, the multi-arc ion coating of the vacuum coating machine is characterized in that the charged ions are bombarded against the substrate and the film layer while being deposited. The bombardment of the ionizable ions produces a series of effects, mainly as follows:

The multi-arc ion plating film layer of the vacuum coating machine is not easy to fall off. Due to the sputtering effect generated by the ion bombardment of the substrate, the substrate is cleaned, activated and heated, and the gas and the contaminated layer adsorbed on the surface of the substrate can be removed, and the oxide on the surface of the substrate can be removed. The heat and defects of the shovel during ion bombardment can cause an enhanced diffusion effect of the substrate. The multi-arc ion plating coating of the vacuum coating machine not only improves the structural crystallization property of the surface layer of the substrate, but also provides the conditions for the formation of the alloy phase.

Multi-arc ion coating machines produce good diffraction properties. Vacuum coating equipment Multi-arc ion plating will encounter multiple collisions of gas molecules on the path of the ionized vapor ions or molecules before reaching the substrate under high pressure (≧1Pa). Multi-arc ion plating of vacuum coating equipment is also deposited at any position on the surface of the substrate with a negative voltage under the action of a power plant. Therefore, this evaporation plating is not possible.

The multi-arc ion plating coating of vacuum coating machine has high quality. Since ion bombardment can increase the density of the membrane, improve the structure of the membrane, and make the uniformity of the membrane layer good, the coating of the multi-arc ion plating coating of the vacuum coating machine is dense, and the pinholes and bubbles are less.

The multi-arc ion plating coating of the vacuum coating equipment has a high deposition rate and a high film forming speed, and can prepare a thick film of 30 & mu; m. The base material and film material used for multi-arc ion plating of vacuum coating machine are relatively wide. Suitable for coating metal, compound, non-metallic materials on metal or non-metal surfaces. Such as steel, non-ferrous metals, quartz, ceramics, plastics and other materials coated on the surface.

Vacuum coating machine in the plastic industry

Vacuum coating machines should be widely used and should be common in the plastics industry. Plastics are involved in life, industry, electrical appliances, aviation and other fields. Plastic has the advantages of easy molding, low price, light weight, anti-corrosion, etc., but the shortcomings of plastic are also prominent. Its shortcomings also restrict the application range of plastics, such as unsightly, easy to age, poor mechanical properties, fragile and easy to change, Poor heat resistance, etc. Through the application of the vacuum coating machine, the surface of the plastic is coated with a specific film layer. The evaporation vacuum coating equipment independently developed by Dongguan Huicheng Vacuum perfectly combines the material of the coating machine with the plastic production, which greatly improves the physical and chemical properties of the plastic products.

First, to improve the surface hardness, the original plastic surface is softer than the metal and vulnerable to damage. Through vacuum coating, the hardness and wear resistance are greatly increased;

Second, make the plastic surface conductive;

Third, easy to clean, no vacuum;

Fourth, improve the appearance of the plastic, the surface is smooth, the metal is strong, the color is bright, and the decoration is greatly improved.
