Process method for producing ardealite cement retarder by changing ardealite crystal structure
The invention relates to the technical field of cement retarders, in particular to a process method for producing an ardealite cement retarder by changing an ardealite crystal structure, which comprises the following steps: S1, preparing materials; s2, material pretreatment; s3, hardening and tempering, homogenizing and forming; s4, catalytic modification reaction; s5, warehousing and stacking; and S6, product delivery. According to the process method for producing the ardealite cement retarder by converting the ardealite crystal structure, part of crystal water in the ardealite is dehydrated in a liquid phase form by utilizing certain temperature and pressure, and harmful impurities contained in the ardealite are effectively removed and digested in the process of changing the ardealite crystal structure; when the phosphogypsum material is applied to cement production, various physical performance indexes of the phosphogypsum material can reach the material performance of natural gypsum.
本发明涉及水泥缓凝剂技术领域,具体是一种通过转变磷石膏晶体结构生产磷石膏水泥缓凝剂的工艺方法,步骤如下:S1、备料;S2、物料预处理;S3、调质、均化与成型;S4、催化改性反应;S5、入库堆存;S6、产品出库。本发明通过转变磷石膏晶体结构生产磷石膏水泥缓凝剂的工艺方法,利用一定的温度与压力将磷石膏中的部分结晶水以液相形式进行脱水,在改变磷石膏晶体结构的过程中将磷石膏中所含有的有害杂质进行有效的去除与消解,从而达到对磷石膏材料物料性能的改变,应用于水泥生产中时,其材料的各项物理性能指标可达到天然石膏的材料性能。
