Retarding type barium silicate cement and preparation method thereof
The invention relates to the field of cement production, in particular to delayed coagulation type barium silicate cement and a preparation method thereof. The preparation method comprises the following steps: S1, cleaning harmful organic matters in phosphogypsum through a cleaning device; s2, the cleaned phosphogypsum is dried; s3, crushing barium carbonate and silica, and grinding into powder; s4, putting barium carbonate and silica powder into a furnace, and heating to obtain barium silicate cement clinker; and S5, mixing and stirring the barium silicate cement and ardealite to prepare the delayed coagulation type barium silicate cement. In the step S4, barium carbonate and silica powder are put into a furnace to be heated to 1400-1450 DEG C. The invention relates to delayed coagulation type barium silicate cement prepared by a preparation method of the delayed coagulation type barium silicate cement. The delayed coagulation type barium silicate cement is prepared from the following raw materials in parts by weight: 5 parts of barium carbonate, 1 part of silica and 1 part of phosphogypsum. Harmful organic matters in the phosphogypsum can be cleaned through the cleaning device, and then the delayed coagulation type barium silicate cement is prepared from the phosphogypsum.
本发明涉及水泥生产领域，更具体的说是一种缓凝型硅酸钡水泥及其制备方法。制备方法包括以下步骤：S1：通过清洗装置对磷石膏中的有害有机物进行清洗；S2：对清洗后的磷石膏进行烘干；S3：将碳酸钡和硅石粉碎后磨成粉；S4：将碳酸钡和硅石粉放入炉中加热，得到硅酸钡水泥熟料；S5：将硅酸钡水泥与磷石膏混合搅拌后制成缓凝型硅酸钡水泥。所述S4中将碳酸钡和硅石粉放入炉中加热至1400‑1450℃。一种缓凝型硅酸钡水泥的制备方法所制备的缓凝型硅酸钡水泥，该缓凝型硅酸钡水泥由以下份数重量的原料组成：碳酸钡5份、硅石1份和磷石膏1份。可以通过清洗装置对磷石膏中的有害有机物进行清洗，然后通过磷石膏制作缓凝型硅酸钡水泥。
