Abstract

PURPOSE:To inhibit dust generation without external heat by mixing a dust- generating substance with a specific polytetrafluoroethylene, and 2 kinds of substances generating reaction heat and fibrillating the resin by applying compression-shear force. CONSTITUTION:A dust-generating powder is mixed with (A) fibrillating polytetrafluoroethylene resin and (B) 2 kinds of substance which react with each other to generate heat such as, in hydration reactions, MgO, CaO, SrO or BaO and water, in oxidation reactions, a metal dust such as Fe, Zn, Mg, Cu dust and oxygen, peroxide or peroxyacid salts. After the temperature of the mixture is raised up to 50-300 deg.C by the reaction heat, compression-shear force is applied to fibrillate the component A whereby the dust is captured by the fibrils.
