长春市建筑工程研究所用长白山浮石(火山灰)研制成新型保温建筑材料泡沫玻璃。1988年9月15日通过省级技术鉴定。此泡沫玻璃是一种整体充满微小气孔(以闭口气孔为主)的玻璃质保温、绝热材料,其具有容重小、强度高、耐候性能好,不吸水等特点。长白山浮石是一种在火山爆发时喷射出来的岩浆,材料来源广泛。研究人员根据长白山
The Changchun Institute of Construction Engineering developed a new type of insulating building material foam glass with pumice (Volcanic Ash) from Changbai Mountain. September 15, 1988 passed the provincial technical appraisal. This foam glass is a kind of glass insulation and heat insulation material which is filled with tiny pores (mainly closed pores) as a whole. It has characteristics of small bulk density, high strength, good weather resistance, and no water absorption. Pumice in Changbai Mountain is a type of magma that was ejected during a volcanic eruption and has a wide range of sources. Researchers According to Changbai Mountain
