以铝矾土为原料,白云石为辅料,添加一定量的复合添加剂,经粉磨、成球和烧成,制备了性能优良的高强度低密度陶粒支撑剂,讨论了复合添加剂掺量及烧成温度对陶粒支撑剂材料性能的影响。结果表明,当白云石掺量为2%,复合添加剂的掺量为6%,烧成温度在1330℃时,制备出的陶粒支撑剂的视密度为2.61g/cm-3,体积密度为1.55g/cm-3,52MPa闭合压力下的破碎率为6.70%。 Using bauxite as raw material and dolomite as auxiliary materials, a certain amount of composite additive is added, and the high strength and low density ceramsite proppant with excellent performance is prepared by grinding, spheroidizing and firing, and the content of the composite additive and Effect of firing temperature on the properties of ceramsite proppant materials. The results show that the apparent density of ceramic proppant is 2.61g / cm-3 when the content of dolomite is 2%, the content of composite additive is 6% and the sintering temperature is 1330 ℃. The bulk density is The breaking rate at closing pressure of 1.55g / cm-3,52MPa was 6.70%.
