(一)新疆超轻陶粒的主要技术性能及其优点(1)容重轻。乌鲁木齐泥岩超轻陶粒的松散容重为320～380公斤/米~3,克拉玛依粘土超轻陶粒的松散容重为300～350公斤/米~3,是目前我国不经水选而直接烧制的容重最轻的陶粒,而且达到了丹麦“莱卡”(200～400公斤/米~3)的性能指标。(2)强度高。泥岩超轻陶粒的筒压强度为12～20公斤力/厘米~2,粘土超轻陶粒为10～20.5公斤力/厘米~2。其值超过我国国家标准中规定的500级陶粒的筒压强度值(不小于10公斤力/厘米~2)。若用比强度指标(筒
(A) The main technical performance and advantages of Xinjiang ultra-light ceramics (1) light weight. The loose bulk density of ultra-light ceramics in mud mud in Urumqi is 320-380 kg/m3, and the loose bulk density of ultra-light ceramic clay in Karamay clay is 300-350 kg/m-3, which is currently produced directly in China without water selection. The lightest weight of ceramic particles, and reached the Danish “Leica” (200 ~ 400 kg / m ~ 3) performance indicators. (2) High strength. The compressive strength of mudstone ultra-light ceramics is 12-20 kgf/cm~2, and clay ultra-light ceramics are 10-20.5 kgf/cm~2. Its value exceeds the cylinder compressive strength of 500 grades (not less than 10 kgf/cm~2) stipulated in our national standards. If the specific strength index (tube
