摘要： PROBLEM TO BE SOLVED: To decrease the concentration of dissolved aluminum in water treated with an aluminum based flocculant, particularly in service water to the concentration considered to be safe for health. SOLUTION: Suspended impurities are removed by flocculation using a hydrated titanium oxide colloid solution deflocculated by hydrochloric acid as a base together with a small content of basic aluminum chloride (PCA) or aluminum sulfate (LAS). The clarifying property matching for the single use of the aluminum based flocculant and the decreased concentration of the dissolved aluminum are attained by using the aluminum based flocculant of Al2O3 combined with the colloidal solution so that Al2O3/(TiO2+Al2O3) ratio is 2-15% expressed in term of TiO2.

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： PROBLEM TO BE SOLVED: To provide a grinding wheel, which can facilitate accurate polishing of a material of hard quality, and very excellent in polishing efficiency as compared with a diamond electro-deposited grinding wheel in the past. SOLUTION: This abrasive material consists of alumina long fiber, diamond abrasive grain, and matrix resin, with the fiber end of the alumina long fiber serving as an abrasive treatment end. This abrasive material is formed in a compound structure of a fiber rich part consisting of the alumina long fiber and the matrix resin and an abrasive grain rich part consisting of the diamond abrasive grain and the matrix resin. The abrasive material comprises, for instance, an UD sheet layer arranging all the alumina long fiber in the same direction to be bound by a thermosetting resin matrix and an abrasive grain layer binding the diamond abrasive grain by the thermosetting resin matrix, the abrasive grain is arranged in at least one surface of obverse/reverse flat surfaces, and a tip end part of the alumina long fiber is integrally formed in flat plate shape so as to be hit to a polishing surface.

摘要： PROBLEM TO BE SOLVED: To improve convenience in use at a work site by forming inorganic fiber as a plate-like braid. SOLUTION: Since a fiber bundle 10 of inorganic fiber 1 is formed as a flat string body 30, the fiber end 1a of the inorganic fiber 1 appears on the tip surface 30a of the flat string body 30 so as to obtain polishing performance. Since the inorganic fiber 1 has an angle to the side surface and a plane in the side surface part 30b and the plane part 30c of the flat string body 30, the fiber end 1a appears only by slightly polishing the surface, so that polishing performance is obtained even in these side surface and plane. Particularly when the side surface part 30b of the flat string body 30 is polished or cut, the fiber end 1a of the inorganic fiber 1 appears in the whole side surface part 30b. When the plane part 30c of the flat string body 30 is polished or cut, the fiber end 1a appears after the inorgnatic fiber 1 is cut in the intersection part of the fiber bundle 10, so that excellent polishing performance is obtained from the beginning. The fiber bundle 10 of this inorganic fiber 1 laterally inclines by 5 to 35 degrees in the polishing direction.

摘要： PROBLEM TO BE SOLVED: To obtain an aluminum chloride solution for spinning capable of assuming a viscosity good in handleability thereof even when the aluminum component is concentrated to a higher concentration than that of a conventional method. SOLUTION: This aluminum chloride solution for spinning is characterized in that the solution comprises only an aluminum chloride represented by the following general formula Al(OH)nCl3-n (wherein, 2.20 =220 g/L aluminum component expressed in terms of aluminum (Al) in the aluminum chloride solution.
