【摘要】：鈦石膏為硫酸法鈦白生產過程中的副產品,鈦石膏大量堆積對環(huán)境造成污染,研究鈦石膏的性能特點,對于選擇合理的回收利用方案具有重要的指導意義。主要對鈦石膏的物相組成、脫水溫度、脫水時間和凝結特點進行試驗研究。結果表明:鈦石膏的主要物相為二水硫酸鈣,少量物相為白云石,鈦石膏脫除結晶水溫度控制在200℃左右,脫除結晶水時間控制在50 min左右較適宜。添加檸檬酸作緩凝劑時,煅燒溫度從120℃提高到200℃,鈦石膏的凝結時間從1 800 s縮短為1 000 s,可以滿足澆注成型的時間要求。
[Abstract]:Titanium gypsum is a by-product in the production of titanium dioxide by sulphuric acid process. A large amount of titanium gypsum accumulates to pollute the environment. The performance characteristics of titanium gypsum are studied. It is of great significance to select a reasonable recycling scheme. The phase composition, dehydration temperature, dehydration time and condensation characteristics of titanium gypsum are studied. The results show that the main phase of titanium gypsum is calcium sulfate dihydrate. A small amount of phase is dolomite, the temperature of crystallization water of titanium gypsum is about 200 鈩，
