中文摘要: 以硬脂酸钠为改性剂,用恒温快速搅拌装置对煅白表面进行改性处理,并对改性前后煅白的结构和表面性质进行表征。结果表明,在改性剂质量分数为5%,改性时间30 min,改性温度50~60 ℃时,煅白表面接触角约为128°,720 min时的吸湿率约为0.35%,而改性前相同时间内吸湿率约为1.89%。
Abstract:Surface of calcined dolomite was modified by sodium stearate in rapid mixing device at constant temperature. Structure and surface properties of calcined dolomite were characterized. The results show that surface contact angle of calcined dolomite is 128° and moisture absorption rate in 720 min drops from 1.89% to 0.35% under the optimum conditions including mass fraction of sodium stearate of 5%, modification time of 30 min, and modification temperature of 50~60 ℃.
