Production process of ether polycarboxylate water reducer mother liquor with high solid content
The invention discloses a production process of ether polycarboxylate water reducer mother liquor with high solid content, wherein the production process comprises the following production process steps: reaction kettle modification and process preparation; the reaction kettle modification step comprises the steps: A, an enamel reaction kettle used in the prior art is replaced with a stainless steel reaction kettle, and the volume and the appearance of the stainless steel reaction kettle are the same as those of an enamel reaction kettle used in the prior art; B, enamel stirring paddles used in the prior art are replaced with stainless steel paddle blade stirring paddles, the volume and the appearance of the stainless steel paddle blade stirring paddles are the same as those of the enamelstirring paddles used in the prior art, and meanwhile, the number of layers of the stainless steel paddle blade stirring paddles is 2-3; and C, finally, a frequency converter is added on an output shaft of a stirring speed reducing motor. According to the invention, an improved reaction kettle and stirring paddle form is adopted, and a water reducing agent polyether hot melt material is adopted toproduce 60-75% of ether polycarboxylate water reducing agent mother liquor with high solid content, so that the production efficiency is improved, and the transportation cost is reduced.
本发明公开了一种高固含的醚类聚羧酸减水剂母液的生产工艺，其生产工艺步骤如下：反应釜改造→工艺制备，反应釜改造步骤如下：A、将现有技术中使用的搪瓷反应釜换成不锈钢反应釜，且不锈钢反应釜的体积和外形与现有技术中使用的搪瓷反应釜相同；B、再将现有技术中使用的搪瓷搅拌桨换成不锈钢桨叶搅拌桨，且不锈钢桨叶搅拌桨的体积和外形与现有技术中使用的搪瓷搅拌桨相同，同时，不锈钢桨叶搅拌桨的层数为2‑3层；C、最后在搅拌减速电机的输出轴上添加变频器。本发明采用改进后反应釜及搅拌桨形式，并采用减水剂聚醚热熔料进行生产60‑75％的高固含量的醚类聚羧酸减水剂母液，提高生产效率，降低运输费用。
