摘　　要：一般来说,原料粒度越细,合成的材料性能越好。该文通过研究支撑剂原料的球磨时间和煅烧温度,探究对于支撑剂影响较大的因素,并优化出最优组合。通过正交优化实验,采用三因素五水平的方案,对铝矾土、长石球磨不同时间和不同的烧结温度进行研究。经过实验发现最优组合为铝矾土球磨4 h,长石球磨8 h,烧结温度为1280℃.最优组合制备的支撑剂的主晶相为刚玉和莫来石,体积密度为1.48 g/cm^(3),视密度为2.7 g/cm^(3),在52 MPa压力下破碎率为4.07%,符合国家标准。Generally,the finer the granularity of raw materials is,the better the properties of synthetic materials will be.In this paper,through studying the balling time and sintering temperature of proppants raw materials,the factor that has a greater impact on the proppants was explored and the optimal combination was proposed.Based on the orthogonal optimization experiment and the three-factor and five-level design scheme,different balling time of bauxite and feldspar and different sintering temperatures of the proppants were carried out.The results show that the optimal combination is A 3 B 1 C 4,i.e.,grinding bauxite for 4 hours,grinding feldspar for 8 hours and sintering the proppants at 1280℃.The main phases of the optimal ceramsite proppants are composed of corundum and mullite,with a volume density of 1.48 g/cm^(3),apparent density of 2.7 g/cm^(3),and a crushing rate of 4.07%under 52 MPa,which is in line with the national petroleum and natural gas industry standards.
