| 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 ℃. |
