Novel chelating low-temperature-resistant coagulator special for brick making
The invention relates to a novel chelating low-temperature-resistant coagulator special for brick making. The coagulator is prepared from the following raw materials in parts by weight: sodium chloride, polyacrylamide, a sodium fluosilicate water reducing agent and citric acid, wherein the proportion of the raw materials is 0.1%-0.2%, the dosage of the sodium chloride is 10%-30%, the dosage of thepolyacrylamide is 20%-40%, the dosage of the sodium fluosilicate water reducing agent is 20%-40%, the dosage of the citric acid is 20%-40%, solid waste, cement and water are adopted as raw materials,and the addition amount of the solid waste is 50%-90%, the addition amount of the cement is 4%-8%, and the addition amount of the water is 20%-40%. The coagulator has the beneficial effects that active substances, electrolyte and surface activity of raw materials are excited and catalyzed, charges on the surfaces of raw material particles are balanced, the thickness of an electric double-layer isreduced, the chemical reaction and physical reaction processes of the mixture are enhanced, the mixture generates a stable complex structure, and no smoke dust is discharged in the production process; watering maintenance is not needed, and the maintenance period is shortened; the strength is increased along with the passage of time, so that the problem about freezing and thawing resistance is thoroughly solved; and compared with a common baking-free brick, the fired brick has the characteristics of being high in strength, good in freezing resistance and free of secondary pollution.
本发明涉及一种制砖专用新型螯合耐低温凝固剂，由以下重量份的原料制备而成：氯化钠、聚丙烯酰胺、氟硅酸钠减水剂和柠檬酸，其比例为0.1％‑0.2％，用氯化钠剂量为10％‑30％，聚丙烯酰胺剂量为20％‑40％，氟硅酸钠减水剂20％‑40％，柠檬酸剂量为20％‑40％，以固废、水泥和水为原材料，其中固废的添加量50％‑90％，水泥添加量4％‑8％，水添加量20％‑40％。有益效果：激发及催化原料的活性物质、电解质和表面活性，平衡原料颗粒表面的电荷，减薄双电层的厚度，加强混合料化学反应和物理反应的过程，使混合料生成稳定的综合体结构，生产过程无烟尘排放；无需浇水养护，缩短了养护周期；强度随着时间的推移而增加，彻底解决了抗冻溶性烧制的砖与普通免烧砖相比，具有强度高、抗冻性好、无二次污染的特点。
