摘要
利用油页岩自身燃烧放出气体后形成孔洞的特性,以吉林省农安地区低品位油页岩为基料,以泥炭为造孔剂、火山渣为添加剂、粉煤灰为增强剂,选用配比为50∶25∶15∶10(油页岩∶泥炭∶火山渣∶粉煤灰),采用湿压成型,在1 050℃下烧结出新型的多孔建筑陶瓷。通过测试和表征,该种陶瓷抗压强度为16.8 MPa,气孔率48.19%,容重1.23 g/cm3,最大孔径约20μm。
A new type of porous construction ceramic was developed with oil shale that produces cavities from releasing gases after combustion. The low grade oil shale in the Nongan area, Jilin Province as a main material, turfs as pore-forming material, volcano dregs as additive and fly ashas intensifier were selected at ratio of 50 ： 25 ： 15 ： 10 （oil shale ： turf ： volcano ： fly ash） and sintered at 1 050 ℃ by extrusion molding. Testing and characterization have shown that compression strength was 16.8 MPa, porosity 48.19%, density 1.23 g/cm^3 , and the biggest pore size was about 20μm in the porous ceramics.
