摘要
以煤矸石矿渣＋粉煤灰矿渣为主料，引入TiO2＋ZnO＋白云石复合矿化剂，通过调整组分配比，优化控制工艺过程、工艺参数，探索支撑剂制备工艺条件及其影响规律，于1330℃～1370℃制备出体积密度为1．54 g/cm3，破损率为3％～5％的低密高强压裂支撑剂．借助于XRD、SEM等手段对其物相组成和表面形貌进行表征．
The low density and high strength proppants were fabricated from coal gangue and flyash as main raw materials and TiO2 ＋ZnO＋ CaMg[CO3 ]2 as composite mineralizers .By optimizing raw materrials proportions and processing parameters ,w hile exploring the prepa-ration conditions and law of impact ,the proppants with low density and high strength were successfully fabricated at sintering temperature of 1 330 ℃ ~1 370 ℃ .The bulk density of the proppant is 1 .54 g/cm3 ,w hile failure rate of the proppant under 69 M Pa closure stress is 3% ~5% .The crystal phase and microstructure of the proppants were investigated by XRD and SEM .
