METHOD OF MANUFACTURING CRYSTALLIZATION ABILITY ENHANCED ROOF TILE CLAY

摘要

PROBLEM TO BE SOLVED: To provide a crystallization ability enhanced roof tile clay as a novel technology by solving problem that good quality roof tile raw soil excellent in fire resistance or the like is depleted and the supply of the deteriorated roof tile raw soil is increased to increase the yield of defective and easily converting natural kaoline, feldspar and silica into modified roof tile clay as a physical property enhancing accelerator.;SOLUTION: The crystallization enhanced roof tile clay is manufactured by mixing high fire resistant/high heat capacity natural kaoline as an aluminum source, silica sand as a silica source and weathered granite/wasted roof tile chamotte as other extenders with natural feldspar to increase the mutual fusion/melting crystallization ability which is a novel technology, wetting and humidifying the whole compound in a pulverizer or a kneader without liquefying the compound slurry-like and after that, homogeneously and finely mixing under a normal temperature and pressure to practically humidify and knead.;COPYRIGHT: (C)2007,JPO&INPIT
