CN105731905A 一种利用工业废渣制备硅酸钙板及其生产工艺 无效 - 撤回

一种利用工业废渣制备硅酸钙板及其生产工艺
摘要：
本发明涉及硅酸钙板的制备技术领域，尤其涉及一种利用工业废渣制备硅酸钙板及其生产工艺。由下述重量百分比组份构成：高炉钢渣：35?45%；粉煤灰：5?15%；脱硫石膏：10?25%；云母粉：1?5%；水泥：15?25%；消石灰粉：5?10%；砂光粉：5?10%；聚乙酰胺：0.05?0.1%，配制成混合料，其中高炉钢渣、粉煤灰和脱硫石膏都为冶炼厂排放固体废物。本发明制作出的硅酸钙板产品，满足国家标准的各项指标要求，产品具不仅能减小工业固废排放对环境的污染，还能起到变废为宝的经济和社会效益。
摘要（英）：

The invention relates to the technical field of production of calcium silicate boards, in particular to a calcium silicate board produced from industrial waste residues and a production technology of the calcium silicate board produced from the industrial waste residues.The calcium silicate board is produced by mixing, by weight, 35-45% of blast furnace steel slag, 5-15% of fly ash, 10-25% of flue gas desulfurization gypsum, 1-5% of mica powder, 15-25% of cement, 5-10% of ground hydrated lime, 5-10% of wood dust and 0.05-0.1% of policapram into a mixture, wherein the blast furnace steel slag, the fly ash and the flue gas desulfurization gypsum are solid waste discharged from a smelting plant.The calcium silicate board, produced by the production technology, meets various index requirements of the national standards, and is capable of not only reducing environmental pollution caused by industrial solid waste discharge but also gaining economic and social benefits by being produced from the industrial waste residues.
