摘要： PROBLEM TO BE SOLVED: To provide an abrasive allowing common use in coarse grinding and finish grinding even for a hard material such as hard steel or hard metal and applicable to precision grinding of a fine part and a small area part such as the groove or the corner part of the mold of a rib and a boss. SOLUTION: Alumina long fibers are bound together by matrix resin containing diamond abrasive grains with a diamond abrasive grain layer on the surface. For example, it is formed into a flat-plate shape having the thickness of 0.45 to 1.2 mm, with the diamond abrasive grain layer on at least either of the wide surfaces of both the front and rear sides thereof. A flat-shaped filament having a ratio of major axis to minor axis of 1.3 to 1.8 in its cross section is used as the alumina long-fiber.

摘要： A flocculant composition comprises an aqueous solution of a mixture of titan yl sulfate or titanium tetrachloride with a water-soluble, neutral alkali or alkaline earth metal salt at a titanium to alkali or alkaline earth metal salt ratio calculated as TiO2 of from 0.25:1 to 0.0002: 1 by weight. The flocculant composition may further contain a water soluble ir on salt at a titanium to iron ratio calculated as TiO2 and Fe2O3 of from 1:1 to 40:1 by weight, or a water-soluble zirconium salt at a titani um to zirconium ratio calculated as TiO2 and ZrO2 of from 1:1 to 40:1 by weight, or a water soluble aluminum salt at a titanium to aluminu m ratio calculated as TiO2 and Al2O3 of from 1:1 to 40:1 by weight. A water-clarifying method comprises the addition of an aqueous solution of titanyl sulfate or titanium tetrachloride to raw water in combination with a water-soluble, neutral alkali or alkaline earth metal with or without further combination with a water soluble iron, zirconium or aluminum salt.

摘要： An abrasive includes an alumina-based fiber bound by a matrix resin which contains diamond abrasive grains therein, and a diamond abrasive grain layer provided on the surface of the bound fiber. The abrasive is formed into, for example, a flat plate having a thickness in a range of 0.45 to 1.2 mm, and the diamond abrasive grain layer is provided on at least any one of opposite surfaces of the bound fiber. Flat filaments having a ratio of a long axis to a short axis of the cross-sectional shape thereof in a range of 1.3 to 1.8 are used for the alumina-based fiber.
