Everyone is very familiar with the pvd coating machine. The industry is different, and the model of the coating machine is also different. But everyone knows that the operating environment of the pvd coating machine is under vacuum, so you must be curious about what the environmental requirements are for the operation of the pvd coating machine? The following is a brief introduction:

The pvd coating machine shall work under vacuum conditions, so the equipment shall meet the requirements of vacuum on the environment. The requirements of vacuum on the environment generally include the requirements of vacuum equipment on the temperature of the laboratory (or workshop), particles in the air and other surrounding environments, and the requirements on the parts or surfaces in vacuum or in vacuum.
These two aspects are closely related. The quality of the surrounding environment directly affects the normal use of vacuum equipment; Whether the vacuum chamber of the vacuum equipment or the parts installed in it are cleaned directly affects the performance of the equipment. If there is a large amount of water vapor and dust in the air, it is difficult to reach the expected vacuum degree by using an oil sealed mechanical pump to pump air without cleaning the vacuum chamber. As we all know, oil sealed mechanical pumps should not be used to remove gases that are corrosive to metals and react with vacuum oil and contain particles and dust. Water vapor is condensable gas. When a large amount of condensable gas is pumped out, the pollution to pump oil will be more serious, resulting in the decline of the pump's limit vacuum and the destruction of the pump's pumping performance.
The dust in the industrial environment is distinguished by powder, eyeless and dust. Powder is the aggregate or dispersion of powder or solid particles. The so-called powder refers to the collection of tiny solid particles, and particles refer to the tiny substances that can be counted one by one. Smog body is a material system that exists in the gas in the floating state of small particles of solid or liquid. Matter, whether solid or liquid, in granular state can be collectively referred to as dust particles. The standard of air cleanliness is determined by the size of the dust particle diameter, so as to customize the grade of the clean room. It is not only suitable for industrial departments with clean requirements, but also suitable for vacuum requirements for a clean environment.
Although the models of pvd coating machines used in each industry are different, their functions, effects and models are different, and the operating environment is the same. Therefore, whether customers or new employees, these technical knowledge should be understood.
