ANTISCATTERING METHOD OF ASBESTOS MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide an antiscattering method of an asbestos material so as not to scatter asbestos from the asbestos material in the case of infill work of the asbestos material. SOLUTION: The antiscattering method of the asbestos material includes a wetting process making the surface of the asbestos material wet by coating the asbestos material with an antiscattering liquid compounded with a aqueous polymer dispersion and cement and having the ratio of 2 to 10 of a polymer cement (capacity ratio), a seepage solidification process infiltrating the prevention liquid up to the inside of the material by spraying the antiscattering liquid on the asbestos material with 4 to 10 kgf/cm2after the completion of the wetting process and curing until a film of the prevention liquid is formed in the surface of the material after that and a surface solidification process compounding the aqueous polymer dispersion and the cement on the surface of the asbestos material after the completion of the seepage solidification process and spraying a solidified liquid having 0.3 to 0.8 of the ratio of the polymer cement (capacity ratio) with 4 to 10 kgf/cm2and forming a solidified layer in the surface of the material.
