摘要
采用差热分析的方法,测定了磷石膏不同条件下的脱水温度,并对磷石膏的凝结硬化性能进行了研究,为石膏低温分解的可行性提供了理论依据,且对缓凝剂的缓凝理论作了适当补充.
The dehydration temperature of phosphogyposum was measured by differential thermal analysis in this paper. The setting and hardening properties of phosphogypsum were researched in this paper. Academic gist is offered for the feasibility for the manufacture of gypsum in lower temperature, the paper is a advisable complementarity for the retarder's theory of retardance.
