Method for producing grinding aid from heavy alcohol rectification polymerization polyol
The invention discloses a method for producing a grinding aid from heavy alcohol rectification polymerization polyol, and belongs to the technical field of building new material cement grinding aids.According to the method for producing the grinding aid from heavy alcohol rectification polymerization polyol. According to the invention, the used heavy alcohol is a by-product in a process of preparing ethylene oxide from ethylene in a certain company, and can be directly used as a raw material of the grinding aid after being subjected to negative-pressure separation treatment with different boiling points; a rectifying tower is ingeniously utilized for physical separation, other special operation and requirements are not needed, and the method is simple and convenient; the product detectedby the National Quality Supervision and Testing Center for Cement meets the national standard, the production cost of the grinding aid is firstly reduced after the filler of our company is added, thelater strength is improved in the cement building material industry, the aggregation of powder particles and the air cushion effect in the crushing process can be prevented, and the flowability and the filling density of cement are improved; and the power consumption of the crusher can also be reduced.
本发明公开了一种重醇精馏聚合多元醇用于生产助磨剂的方法，属于建筑新材料水泥助磨剂技术领域。本发明提供的一种重醇精馏聚合多元醇用于生产助磨剂的方法，使用的重醇为某公司乙烯制环氧乙烷工艺过程中的副产品，经过沸点不同负压分离处理后，就可以直接作为助磨剂原料；巧妙地利用精馏塔物理分离，无需其他特别操作和要求，方法简单便捷；产品通过国家水泥质量检验中心检测，符合国标，通过添加我公司填料后首先降低助磨剂生产成本，在水泥建材行业使用提高后期强度不仅可以防止粉碎过程粉粒的聚集和气垫作用，提高水泥的流动性和装填密度，而且也可降低粉碎机的动力消耗。
