Since the emergence of vacuum coating industry in the 1930s, it has been applied in industrial production, and has been widely used in simple industries such as electronics, aerospace, decoration, packaging and so on since the 1980s.
The principle of vacuum coating refers to the deposition of a metal or a metal compound on the surface of a specified material in a vacuum environment to form a coating, so it is called vacuum coating for short.
Vacuum coating can be subdivided into evaporation coating, sputtering coating and ion coating according to its different production processes. The materials used also evolve from simple metals into many kinds of high purity oxides, high purity metals, mixtures and other compounds. So the raw materials for coating are also varied, the most common are plastics, paper, ceramics, wood and so on, which are widely used in automobiles, household appliances, daily necessities, process decoration and so on. Many materials have rough and unsightly exterior. After coating, the wear resistance, aesthetics and application range of the surface can be greatly increased. With the rapid development of technology, vacuum coating technology will be more and more used in our daily life.
So what role does the rotary vane vacuum pump play in vacuum coating?
Rotary vane vacuum pump is an essential part of vacuum coating. So, what is the use of Kaide rotary vane vacuum pump in the production of vacuum coating? The most important role of rotary vane vacuum pump is of course vacuum pumping, because vacuum coating is necessary to complete the process in a vacuum environment, so it is essential to vacuum pump. When the coating is evaporated into molecules or atoms, it is the most primitive linear motion in vacuum environment. When the coating material encounters the specified material, it will deposit on the specified material and form the coating layer. When the vacuum pumping is not clean and there are still air molecules left, the air molecules will oxidize when they encounter the coating atoms, resulting in the generation of impurities in the coating materials, and sometimes the deposition of the coating materials will be organized, so the coating can not be made. It can be seen that the rotary vane vacuum pump is indispensable in the coating process, but also is the guarantee of perfect quality, so that the production of coating products will be perfect.
At present, rotary vane vacuum pump plays a leading role in vacuum coating industry. Dongguan Punok Vacuum Technology Co., Ltd. is a vacuum expert beside you.
