Method for preparing environment-friendly process stone by harmlessly curing industrial waste gypsum
A method for preparing environment-friendly process stone through harmless curing of industrial waste gypsum comprises the following steps that S1, wet industrial waste gypsum and an alkalization water-retaining agent are placed in a mechanical mixing device and stirred to be uniform, and an alkaline water-retaining gypsum material is obtained; and S2, adding a hydraulic cementing material and a heavy metal curing water repellent agent into the alkaline water-retaining gypsum material obtained in the step S1, continuously stirring and uniformly mixing, feeding into a process stone compression molding machine, pressing into process stone, and carrying out normal-temperature natural curing or damp-heat curing or dry-steaming curing for a proper time, thereby obtaining the water-retaining gypsum material. The method is simple in process and free of secondary pollution; the method is simple in process, low in investment, large in treatment capacity of harmless resource utilization of wet phosphogypsum and desulfurized gypsum, low in operation cost and capable of effectively solving the problem that the phosphogypsum and the desulfurized gypsum severely pollute environmental water and soil for a long time; the prepared product can meet the requirements of outdoor projects such as municipal gardens, engineering rivers and ditches, road renovation and slope protection on environment-friendly artificial craft stones.
一种用工业废石膏无害化固化制环境友好型工艺石的方法，包括以下步骤：S1，将湿态工业废石膏与碱化保水剂置于机械混合装置内，搅拌均匀，得碱性保水石膏料；S2，在步骤S1所得的碱性保水石膏料中，加入水硬性胶凝材料、重金属固化疏水剂，连续搅拌混合均匀，送入工艺石模压成型机压制为工艺石，于常温自然养护或湿热养护或干蒸养护适当时间，即成。本发明工艺简单，无二次污染；投资较低，对湿态磷石膏、脱硫石膏无害化资源化利用处理量大，运营成本较低，可有效化解长期以来磷石膏脱硫石膏对环境水土的严重污染问题；制得的产品可满足市政园林、工程河流沟渠及道路整修和护坡等室外工程对环境友好型人造工艺石的需求。
