We use a Vanguard V6500 centrifuge to degass the epoxy before injecting it into the ferrule. These units run smooth and work great. The centrifuges below were not used in our production facility. We purchased these for the purpose of resale.
All V6500 units have been checked out, thoroughly cleaned and any needed parts have been replaced.
Why do we degass our epoxy before applying?
Gaseous bubbles trapped in a liquid, although initially microscopic in size, will expand when heated and can grow to become large enough to cause problems.
Centrifuging can also be used to remove air from unfilled adhesives. By centrifuging the material at 1,000-3,000 rpm for 1-2 minutes will remove any entrapped air in the adhesive.
For some applications degassing of the adhesive is necessary. Vacuum degassing and centrifuge are common methods to remove entrapped air. Vacuum degassing requires an ordinary vacuum pump and vacuum chamber. An efficient pump should be capable of pulling a vacuum of 29 inches Hg at a quick rate of speed. Vacuum should be held for minimum amount of time to remove the entrapped air. Try to minimize the amount of time the vacuum is applied and do not create a ?rolling boil? effect. Care should be taken that only a small amount of adhesive is filled into a large container (typically 5-10 times the adhesive volume). During the vacuum process, the adhesive swells up considerably and can spill out of the container. Applied vacuum along with agitation/vibration will effectively remove any entrapped air.
