Preparation method of alkali-free liquid accelerator
The invention belongs to the technical field of preparation of accelerators, and particularly relates to a preparation method of an alkali-free liquid accelerator. Aiming at the problem that most of the existing accelerators are alkaline liquid and are easy to cause environmental pollution and even cause pollution or damage to vegetation, the invention provides the following scheme: the preparation method comprises the following steps: S1, preparing aluminum sulfate, a preservative, an antioxidant, a shaping agent, an acid solution and water; S2, firstly adding the water into a mixer, adding the aluminum sulfate liquid, performing mixing, and controlling the temperature; S3, intermittently adding the preservative, the antioxidant and the shaping agent; S4, intermittently adding the acid solution for mixing, and detecting the pH value all the time; and S5, filtering the liquid by adopting a filter screen, filtering out impurities, and packaging the liquid. The alkali-free liquid accelerator is convenient to prepare, the acid solution can be simply extracted, preparation and extraction are simple, the cost is reduced, and environmental pollution and damage can be avoided.
本发明属于速凝剂的制备技术领域，尤其是一种无碱液体速凝剂的制备方法，针对现有的速凝剂多为碱性液体，容易造成环境污染，甚至对植被造成污染或破坏的问题，现提出如下方案，其包括包括以下步骤：S1：准备硫酸铝、防腐剂、抗氧剂、塑形剂、酸性溶液和水；S2：将水首先加入混合器中，将硫酸铝液体加入进行首先混合并控制温度；S3：间歇性加入防腐剂、抗氧剂和塑形剂；S4：间歇性加入酸性溶液混合，并时刻检测PH值；S5：采用滤网对液体进行过滤，将杂质滤除，将液体封装即可。本发明制备方便，可以简易的提取酸性溶液，制备提取简单，降低了成本，可以避免造成环境污染和破坏。
