By vacuum degassing furnace by filling nitrogen and nitrogen for heating in a vacuum cavity from the air, water, oil etc.:
1, can greatly shorten the vacuum coating, vacuum coating chamber vacuum time;
2, reduce the gas furnace system and vacuum coating system of oxygen corrosion, prolong the equipment use time.
3, the product surface will not be accompanied by gas bubbles, enhance the adhesion of the vacuum coating.
4, for vacuum coating, the formation of the film to provide a good vacuum environment.
5, to ensure the normal operation of the system stable and reliable.
6, equipment installation is convenient, automatic operation, safe and reliable, easy to repair and maintenance.
