Which kind of material of drive belts or conveyor’s when used it in the vacuum environment is always a issue.
Compared
with normal atmosphere , the vacuum environment have
these characteristic list as
below
- the lower pressure
- more collision of gas molecules
- oxygenized difficult
- hard to cooling down
- the boiling point is lower
- hard to transaction the electricity
Due to these features, the
vacuum
atmosphere
are wildly used in a
number
of applications,
first
of Freezing Dry of coffee beans, LCD, Solar Batteries, Blade Processing, Vapor
depositing, sputtering working process and etc.
It is
necessary to move or transportation workpieces
in
the vacuum chamber.
For
drive belts
and transportation belts, why we should choose stainless steel belts but not resin
belts or plastic belts?
Here
are the reasons
- Dense oxide layer makes less gas adsorption
- Almost no release of outgas like rubber and plastics, help maintains negative pressure
- The lubricating oil is not needed since the metal belt moves in the friction conduction
- Since less dusting than rubber belt or a resin belt, stainless steel belt is hardly contaminate the inside of the chamber
- Stainless steel belt has to demonstrate the performance especially under high vacuum environment
