Title: Adsorbent layers for vacuum equipment - prepd. by bonding preheated adsorbent to substrate using nitrocellulose or water glass as binder
Inventor: KELLNER ECKHARD
IPC: C09D5/00
Filed: 1975-08-13
Abstract: Layers are prepd. by preheating the adsorbent, pref. zeolite, Al2O3, activated charcoal or mixts. of these in granular or powder form, in vacuo. The adsorbent is then applied manually or mechanically to a substrate previously coated with a binder, pref. nitrocellulose or water glass. Layers are useful in cryoscopic vacuum equipment e.g. the cold surfaces of low temp. vacuum pumps, freeze driers, etc. In the vacuum equipment used up to now the heat transfer to the adsorbent is so bad that neither the preheating temp. of 300 degrees C nor the operating temp. of 77 degrees K can be easily reached. Such adsorbents can only achieve a vacuum of 10-4 to 10-6 Torr in closed vessels (e.g. Dewar flasks) and 10-2 to 10-3 in vacuum pumps. By use of the invention, heat transfer to the adsorbent is highly efficient and both preheating at 300-400 degrees C and cooling to 77 degrees K is easy. A vacuum of 10-8 Torr can therefore be attained.
