Applications of Vacuum Technology
With the rapid advance of vacuum acquisition technology, application of vacuum has expended to all aspects of industry and scientific researches.
The wide range of vacuum applications includes low vacuum, medium vacuum, high vacuum, and ultrahigh vacuum applications.
Low vacuum utilizes the pressure differential obtained from low (or coarse) vacuum to clamp, lift and transport materials, as well as collection and filtration of dust.
Medium vacuum is usually applied to remove gas or water absorbed or dissolved in materials, also making bulbs, vacuum metallurgy, and insulating heat.
High vacuum can be used in the situations where there are thermal insulation, electrical insulation and the avoidance of collisions of molecular electronic and ion.
Because its molecular free path is larger than the container linear size, which can also be considered as a special application to vacuum coating in fields of optical, electrical and decorative plating.
It is admitted that the energy transfer in outer space is similar to that in UHV(Ultra High Vacuum), so UHV can make sense for space simulation.
