摘要
以蒙古国某典型斑岩型铜矿尾矿为主要原料,添加钠长石、高岭土、发泡剂SiC,制备轻质多孔陶瓷材料。通过正交实验研究了物料配比、粉磨时间、发泡剂种类、发泡剂用量和烧成温度对轻质多孔陶瓷表观密度和抗压强度的影响。当m(铜尾矿)∶m(钠长石)∶m(高岭土)为6.4∶2.7∶0.9、粉磨时间为15 min、发泡剂(SiC)掺量为0.1%、烧成温度为1180℃、保温时间为60 min时,获得的多孔陶瓷材料表观密度为580 kg/m3,抗压强度为4.90 MPa,软化系数为0.92。
Lightweight porous ceramic materials is prepared from flotation tailings of a typical porphyry copper ore in Mongolia,albite,kaolin and foaming agent SiC.The effects of material ratio,grinding time,foaming agent type,foaming agent dosage and sintering temperature on the apparent density and compressive strength of lightweight porous ceramics are studied by orthogonal tests.When the ratio of m(copper tailings)∶m(albite)∶m(kaolin)is 6.4∶2.7∶0.9,the grinding time was 15min,the content of foaming agent(SiC)was 0.1%,the sintering temperature was 1180℃and the holding time was 60min,the technological process was the best.At this time,the apparent density of porous ceramic material was 580 kg/m3,the compressive strength was 4.90 MPa and the softening coefficient was 0.92.
