What are the environmental requirements of the vacuum coating machine?- Ningbo Honyu Vacuum Technology Co., Ltd.

The environmental requirements of the vacuum coating machine generally include the requirements of the vacuum equipment for the temperature of the laboratory (or workshop), the surrounding environment such as particles in the air, and the requirements for parts or surfaces in a vacuum state or vacuum.

These two aspects are closely related. The quality of the surrounding environment directly affects the normal use of the vacuum equipment; and whether the vacuum chamber of the vacuum equipment or the parts loaded into it is cleaned, it directly affects the performance of the equipment.

If the air contains a lot of water vapor and dust, it is difficult to achieve 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 are not suitable for pumping out gases containing particulate dust that are corrosive to metals and react to vacuum oil. Water vapor is a condensable gas. When a large amount of condensable gas is pumped out, the pollution to the pump oil will be more serious. As a result, the ultimate vacuum of the pump will drop, and the pumping performance of the pump will be destroyed.

Dust in the industrial environment is distinguished by powder, untitled, and dust. A powder is a substance in an aggregated or dispersed state of powder or solid particles. The so-called powder refers to the collection of tiny solid particles, and the particle refers to the tiny substances that can be counted one by one.

Smoke is a system of substances in which tiny particles of solid or liquid exist in a gas in a floating state. Matter, whether solid or liquid, in the form of particles can be collectively referred to as dust particles. The standard of air cleanliness is determined by the size of the particle diameter, so as to customize the level of the clean room. It is not only suitable for industrial sectors with clean requirements, but also suitable for vacuum requirements for clean environment.
