  • Publication number: 20200261334
    Abstract: Aqueous dispersions which exhibit properties required of an aqueous dispersion and achieve stability and homogeneity include inorganic particle groups dispersed in an aggregation state in water. In this dispersion, when the total mole number ratio represented by moles of surface hydrophilic groups of the inorganic particle groups moles of surface hydrophobic groups is within a prescribed lower limit value or more depending on the aggregating properties of inorganic particles, the inorganic particle groups contain self-micelle-like aggregates and hydrophobic-rich aggregates.

  • Patent number: 6221311
    Abstract: A method for disposing synthetic resinous material comprises: dechlorinating a synthetic resinous material by heating the synthetic resinous material and decomposing the same; and supplying the synthetic resinous material into the furnace as a fuel or a reducing agent. An apparatus comprises: a chlorine removing means for dechlorinating the synthetic resinous material by heating the synthetic resinous material; and a pulverizer for pulverizing the dechlorinated synthetic resinous material, a supply means for supplying the processed synthetic resinous material into a furnace.
