Abstract
A method of producing a pre-wet, dust-free form of asbestos short fibers comprises admixing about 60-90% by weight of asbestos short fibers with about 10-40% by weight of liquid in a manner so as to produce an agglomerated product, with the liquid including a relatively non-volatile binder comprising about 5-40% of the product, a sufficient quantity of a solvent or volatile component to reduce the viscosity of the liquid to a level that permits easy formation of an agglomerate, and a sufficient quantity of a surfactant to cause thorough wetting of the fibers in the product. The agglomerated product is stored for at least about 24-72 hours after production so as to permit the liquid to completely infiltrate and fully wet the agglomerated product. Hydrophilic liquids are used to produce asbestos agglomerate designed for admixture with predominately polar materials, organophilic liquids are used for producing asbestos agglomerate prepared for admixture with non-polar materials. The resulting compositions are pre-wet for easy admixture with materials of like polarity and remain in an agglomerated, dust-free form during storage and handling for an indefinite period of time.
