METHOD OF DUST SUPPRESSION DISPOSAL

摘要

A method of dust suppression disposal for dust generating material, and relevant dust suppression disposal matter from dust generating material, in which the possibility of environmental problems while exhibiting a high dust suppression efficacy equivalent to those of conventional methods can be lowered by the use of a dust suppression disposal agent composition comprised of a water-base dispersion of PTFE ensuring a low possibility of environmental problems. There are provided a method of dust suppression disposal for dust generating material, and relevant dust suppression disposal matter from dust generating material, wherein a dust suppression disposal agent composition comprising a water-base dispersion of polytetrafluoroethylene in which a fluoroemulsifier is contained at a content of <= 50 ppm is mixed with a dust generating material and thereafter compression-shear action is applied at about 20 to 200°C to the mixture so that the polytetrafluoroethylene is fibrillated to thereby suppress dusting of the dust generating material.
