Heat Treatment of Chtysotile Asbestos Fibers
A commercial method .has 1been developed for controlling. the texture of chrysotile asbestos fibers so that they may possess properties comparable with natural se.m1-harsh fibers for use in wet processes. The 1physical properties of the ~aft, silky and slimy fibers are .partially altered by a flash-~eating process which removes a port10n of the molecular water. The heat-treated fibers show an improvement in filterability, an increase in bulk, abso1iptwn, and surface area and better electrical p1roperties, such as volume resistivity.
