摘要： Dust-control treatment of dusty powder, which mainly passes through a 100 mesh sieve, such as pigment and fertilizer, is achieved by, firstly blending the dusty powder with fibrillatable polytetrafluoroethylene and a pair of materials capable of initiating an exothermic reaction upon contact, and then subjecting the blended material to compression-shear under the exothermic reaction and raising the temperature of the blended material to 50.degree.-300.degree. C. The polytetrafluoroethylene fibrillates during the compression-shear and the formed fibrils enclose the dusty powder to turn it to a dust-controlled one.

摘要： It is an object of the present invention to provide a soil-stabilizing agent with less emission of dust, good reactivity, good behavior at mixing and good dispersibility and a method for soil stabilizing treatment capable of restraining the emission of dust in the procedure of sprinkling and mixing of the soil-stabilizing agent to soil.The soil-stabilizing agent according to the present invention comprises a mixture of a material mainly composed of quick lime and/or calcined dolomite and fibrillatable polytetrafluoroethylene resin.And the method for soil-stabilizing treatment according to the present invention comprises the following steps; adding a mixture of a material mainly composed of quick lime and/or calcined dolomite and fibrillatable polytetrafluoroethylene resin to soil, and mixing them under the hydration heat generated by the reaction between the quick lime and/or calcined dolomite with moisture in the soil to form hydrated material.When PTFE is in partially fibrillated state, emission of dust while sprinkling (primary dust) from the soil-stabilizing agent will be restrained as the particles of quick lime and/or calcined dolomite are enclosed in a cobweb-like net of the partially fibrillated PTFE, and emission of dust while mixing (secondary dust) is further restrained by a cobweb-like net of PTFE fibrillated further by mixing under hydration heat generated by the reaction of quick lime and/or calcined dolomite with moisture in the soil.
