Abstract
PURPOSE:To obtain a formed porous ceramic article by adding a sintering assistant and an organic binder to the subject industrial waste and forming, drying and calcining the mixture. CONSTITUTION:Industrial wastes (a substance composed of an organic substance and an inorganic substance finely mixed with each other) such as sewage sludge, sludge of sewage treatment system, waste generated from paper mill, etc., is added with a sintering assistant and then with an organic binder and the mixture is formed. The sintering assistant is e.g., glass raw material such as clay, glass powder, silica sand and borax, kaolin, glaze, waste sand of pottery mill or slag and the organic binder is e.g., water-base bond or starch paste. The formed product is dried and baked in a high-temperature furnace at >=800 deg.C to obtain the objective product. The product has a light weight (a specific gravity of about 1.5-3.0), fire resistance and heat-insulation property. An additive such as sandy clay or diatomaceous earth is added to the product according to the required specific gravity, crush strength and abrasion strength to obtain light-weight aggregate, tile, etc.

た物質とする事であります。[Scope of Claims] The present invention involves adding a sintering aid to sewage sludge, waste treatment sludge, industrial waste generated in paper factories, etc. (substances containing a fine mixture of organic and inorganic substances), and using the mixture for molding. This involves the production of porous ceramics by adding an organic binder, molding, drying, and firing in a high-temperature furnace (800°C). The products produced by this method have a specific gravity of 1.5 or less, are lightweight, fire-resistant and heat-insulating, and can be used in a variety of ways.The specific gravity, compaction strength, and degree of abrasion can be adjusted with additives to create lightweight aggregate (artificial stone) tiles, kneaded materials, etc. We manufacture a variety of molded products such as plastics, boards, etc. Also, the feature of this manufacturing method is that organic substances among the toxic substances in the raw materials are removed by thermal decomposition, and inorganic substances (lead, mercury, arsenic, chromium, etc.) are converted into oxides and made into insoluble, harmless and stable substances by sintering. It is a matter of fact.
