Alkali-free accelerator preparation process
The invention discloses an alkali-free accelerator preparation process, and relates to the technical field of alkali-free accelerator preparation, and the alkali-free accelerator preparation process comprises the following steps: step 1, raw material preparation, step 2, stirring and mixing, step 3, filtering, step 4, evaporation and concentration, step 5, cooling, and step 6, stirring and dissolving. The preparation method comprises the following steps: preparing raw materials such as aluminum sulfate, a complex forming agent, an organic reinforcing agent, a pH regulator and a dispersing agent, dissolving the aluminum sulfate in water, adding the complex forming agent in a water bath heating manner, adding the organic reinforcing agent and the pH regulator, and mixing in a reaction kettle; by adding the complex-doped forming agent, the saturation concentration of AI < 3 + > SO4 < 2-> in the liquid accelerator can be remarkably improved, the performance of the liquid alkali-free accelerator is more excellent, by adding the organic reinforcing agent, the shrinkage reducing and crack resisting effects of cement can be improved, the anti-seepage and waterproof performance is greatly improved, meanwhile, the liquid alkali-free accelerator has the anti-corrosion and anti-corrosion functions, and the service life of the liquid alkali-free accelerator is prolonged. Therefore, the use effect of the alkali-free accelerator is improved.
本发明公开了一种无碱速凝剂制备工艺,涉及无碱速凝剂制备技术领域,包括以下步骤,步骤一,原料准备,步骤二,搅拌混合,步骤三,过滤,步骤四,蒸发浓缩,步骤五,冷却,步骤六,搅拌溶解。本发明通过准备硫酸铝、络合物形成剂、有机增强剂、ph调节剂和分散剂等原料,之后将硫酸铝溶解于水中,然后用水浴加热的方式加入络合物形成剂,再加入有机增强剂和ph调节剂放入反应釜中混合,通过加入掺络合物形成剂的可以使液体速凝剂中的AI3+SO42-的饱和浓度得到了显著的提高,使液体无碱速凝剂性能更加优异,而加入有机增强剂能增加水泥的减缩抗裂功效,大幅度提高了抗渗防水性能,同时具有抗蚀防腐功能,从而增加无碱速凝剂的使用效果。
