Grinding aid for caprolactam-containing mixed waste liquid and application of grinding aid
The invention discloses a grinding aid for caprolactam-containing mixed waste liquid and application of the grinding aid. The grinding aid comprises a micro-powder carrier and a liquid grinding aid, wherein a weight ratio of the micro-powder carrier to the liquid grinding aid is 10: (1-5). The micro-powder carrier is prepared through the steps that palygorskite powder is added into hydrochloric acid, ultrasonic treatment is conducted for 1-2 h at a temperature of 80-100 DEG C, then filtering is conducted, washing with water is conducted 2-5 times, drying is conducted, then the mixture is added into a sodium chloride solution for soaking for 1-2 h, cetyltrimethylbromochloramine and ammonia water are added, stirring is conducted for 20-40 min, and filtering, washing, drying, smashing and sieving with a 60-to-100-mesh sieve are successively conducted. According to the invention, the mixed waste liquid is fully utilized for producing the cement grinding aid, so the waste is fully utilized and turned into the wealth, the use of other grinding aid materials is greatly reduced, production cost is reduced, the quality of cement is also improved, and good social benefits and economic benefits are achieved.
本发明公开了一种含己内酰胺的混合废液的助磨剂及其应用，包括微粉载体与液态助磨剂，微粉载体与液态助磨剂的重量比为10：1‑5；在微粉载体中，将坡缕石粉加入至盐酸中，在温度80‑100℃超声处理1‑2h，过滤，用水洗涤2‑5次，干燥后加入至氯化钠溶液中浸泡1‑2h，加入十六烷基三甲基氯溴胺、氨水搅拌20‑40min，过滤，洗涤，干燥，粉碎过60‑100目筛，得到微粉载体。本发明充分利用混合废液用于生产水泥助磨剂，充分利用废弃物，变废为宝，同时大幅减少其他助磨材料的使用，降低了生产成本，也提高了水泥的质量，具有良好的社会效益和经济效益。
