摘要: An inorganic composition useful as material for Lehr rolls at temperatures above 500°C consists essentially of 15-45% chrysotile asbestos, 40-75% talc component and 2-35% binder. The is also used in manufacturing millboard by forming a water slurry said transferring to rotating screen cylinder, then moving belt drum upon which layers accumulate each other are thereafter slit, dried formed into flat sheet.
