The quality of the surrounding environment of vacuum silver plating directly affects the normal use of vacuum equipment

The requirements of vacuum on the environment 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 inside the installation are cleaned directly affects the performance of the equipment. If the air contains a lot of water vapor and dust, it is difficult to achieve the desired vacuum degree by using an oil-sealed mechanical pump to pump air without cleaning the vacuum chamber. It is well known that oil-sealed mechanical pumps are not suitable for pumping gases that are corrosive to metals, chemically react to vacuum oil, and contain particulate dust. Water vapor is a condensable gas. When the pump removes a large amount of condensable gas, 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.

Vacuum silver plating needs to work under vacuum conditions

Since the vacuum coating equipment works under vacuum conditions, the equipment must meet the requirements of vacuum for the environment. The industry standards for various types of vacuum coating equipment made in my country (including general technical conditions for vacuum coating equipment, vacuum ion coating equipment, vacuum sputtering coating equipment, and vacuum evaporation coating equipment) have clearly stipulated environmental requirements. Only by meeting the environmental requirements of vacuum coating equipment can the equipment operate normally, and with the correct coating process, qualified coating products can be produced.
