Improved grinding aid
The invention discloses an improved grinding aid which comprises the following components: triethanolamine, sodium lignin sulfonate, sodium chloride, sugar ether, sodium acetate, potassium chloride, sodium hydrogen sulfate and a chromium removing agent, wherein the input amount of the triethanolamine is 180-220 g/L, the input amount of the sugar ether is 50-80 g/L, the input amount of the sodium phosphate is 5-10 g/L, the input amount of the sodium lignin sulfonate is 30-50 g/L, the input amount of the sodium chloride is 120-150 g/L, the input amount of the sodium acetate is 50-80 g/L, the input amount of the potassium chloride is 20-30 g/L, the input amount of the sodium thiocyanate is 30-50 g/L, and the input amount proportion of the chromium removal agent is 0.9%. The chromium removing agent is added into the grinding aid, and hexavalent chromium ions in the grinding material are removed through the chromium removing agent, so that the content of harmful substances, namely water-soluble hexavalent chromium, in the produced cement material is reduced, and the cement material meets the national standard range.
本发明公开了一种改善型助磨剂，所述改善型助磨剂组成成分包括：三乙醇胺、木质素磺酸钠、氯化钠、糖醚、醋酸钠、氯化钾、硫酸氢钠和除铬剂，所述三乙醇胺投入量为180‑220g/L、糖醚投入量为50‑80g/L、磷酸钠投入量为5‑10g/L、木质素磺酸钠投入量为30‑50g/L、氯化钠投入量为120‑150g/L、醋酸钠投入量为50‑80g/L、氯化钾投入量为20‑30g/L、硫氰酸钠投入量为30‑50g/L、除铬剂投入量比例为0.9％。本发明在助磨剂中添加除铬剂，通过除铬剂将磨料中的六价铬离子去除，使得生产的水泥物料中有害物质水溶性六价铬含量减低，并符合国家标准范围。
