苏联莫斯科Mosoblasttroj CNiIL研究所用纤维素纸废液研制出一种新型绝热材料。该材料由20～60％的机械净化的纤维素废水沉淀物、珍珠岩以及20％的沥青胶凝材料组成,由于含有木质纤维和纤维素纤维(作增强材料,干容重为500公斤/米~3),这种材料的绝热性能和物理力学性能良好。绝热材料的干容重为150～350公斤/米_3,抗弯强度为0.1～0.52兆帕。抗压强度为0.15～0.35兆帕,吸水率为5～15％,导热率为0.05～0.093瓦/米·℃,且抗
The Soviet Union Moscow Mosoblasttroj CNiIL Research Institute developed a new type of thermal insulation material from cellulose waste paper. The material consists of 20 to 60% mechanically purified cellulose wastewater deposits, perlite, and 20% bituminous cementitious materials. Due to the presence of wood fiber and cellulose fibers (for reinforcement, the dry bulk density is 500 kg/m~ 3) This material has good thermal insulation properties and physical and mechanical properties. The heat-insulating material has a dry bulk density of 150-350 kg/m3 and a bending strength of 0.1-0.52 MPa. Compressive strength is 0.15～0.35 MPa, water absorption is 5～15%, thermal conductivity is 0.05～0.093 watts/m·°C, and resistance
