Liquid accelerator and preparation method thereof
The invention discloses a preparation method of a liquid accelerator. The liquid accelerator is characterized in that the liquid accelerator comprises the following components: 900-1200 parts of water, 50-60 parts of sodium metaaluminate, 90-110 parts of a catalyst, 1100-1300 parts of aluminum sulfate and 70-90 parts of caustic soda flakes. The preparation method of the liquid accelerator comprises the following steps: dissolving sodium metaaluminate and caustic soda flakes in water to form a mixed solution; and spraying the mixed solution and the catalyst into a stirring tank from the top of the stirring tank in the production system, and meanwhile, spraying aluminum sulfate powder into the stirring tank from the side surface of the stirring tank at the same time, so that the raw materials are mixed and contacted in the stirring tank and are stirred to react. According to the system, powder raw materials and other liquid materials can be fully mixed, the raw materials are fully reacted through heating and dissolving, and the reaction speed is increased. According to the method disclosed by the invention, powder raw materials and other liquid materials can be fully mixed, the raw materials are fully reacted by heating and dissolving, the reaction speed is accelerated, and the prepared liquid accelerator can quickly play a role in hydration after being mixed with cement, so that a rapid hardening effect is achieved.
本发明公开了一种液体速凝剂的制备方法，其特征在于，包括以下组分的成分：水900‑1200份、偏铝酸钠50‑60份、催化剂90‑110份、硫酸铝1100‑1300份、片碱70‑90份，其中该速凝剂的制备方法是将偏铝酸钠、片碱溶于水中形成混合溶液，再将该混合溶液、催化剂从生产系统中的搅拌罐的顶部喷入搅拌罐，同时将硫酸铝粉末从搅拌罐的侧面喷入搅拌罐中，使各个原料在搅拌罐中混合接触并进行搅拌使其反应。本发明的系统能够将粉末原料和其他的液体物料进行充分混合，并且加热溶解使原料充分反应，加快反应速度。本发明的方法能够将粉末原料和其他的液体物料进行充分混合，并且加热溶解使原料充分反应，加快反应速度，制备的液体速凝剂与水泥混合后能快速起水化作用，达到速凝效果。
