苏联拉脱维亚苏维埃社会主义共和国建材部建材工业托拉斯磷酸盐材料试验室研制出一种保温隔热材料——磷酸珍珠岩混凝土制品。这种新材料是热力设备有效的高温(达1000℃)绝缘体。它主要用于建筑业和建材工业窑炉的维修。
The Institute of Building Materials Industry Trust of the Ministry of Building Materials of the Soviet Socialist Republic of Latvia in the Soviet Union developed a thermal insulation material, a perlite phosphate concrete product. This new material is an effective high temperature (up to 1000°C) insulator for thermal equipment. It is mainly used for the maintenance of kilns in the construction industry and building materials industry.
