烧结温度对添加固废陶粒制备支撑剂性能影响
|
摘要
以铝矾土(Al_2O_3<60wt%)为主要原料,锰矿粉及白云石为烧结助剂,添加一定量固废陶粒砂,在不同温度下烧结制备压裂支撑剂,研究烧结温度对支撑剂结构及性能的影响。结果表明:添加一定量固废陶粒砂经低温烧结(1 260℃)制备的支撑剂,其主晶相为刚玉,次晶相为莫来石和钙长石;支撑剂的体积密度为1.65 g/cm~3,52 MPa闭合压力下破碎率为8.5%,满足行业标准SY/T5108-2014要求,说明添加一定量的固废陶粒砂没有降低支撑剂的使用性能。
Proppant was prepared using bauxite as main raw material and manganese powder and dolomite as sintering aids with a certain amount of waste ceramsite. The effects of sintering temperature on the structure and performance of the proppant were investigated. The results show that the proppant adding a certain amount of waste ceramsite is sintered at low temperature( 1 260 ℃),its main phase is corundum,the secondary phases are mullite and calcium feldspar. Meanwhile,the proppant exhibits a bulk density of 1. 65 g/cm3 and a breakage ratio of 8.5% at 52 MPa closed pressure,which meets the requirements of industry standard SY/T5108-2014.
