Status and Prospects of Development of Production of Glassy Foamed Heat-Insulation Materials

Аннотация

The advantages and disadvantages of heat insulation materials offered on the construction market in the Commonwealth of Independent States are presented. It is noted that on the basis of all characteristics taken together foam glass surpasses well-known heat insulation, but it is expensive because the production is energy intensive, which makes it uncompetitive. Anew, promising trend is examined—low temperature synthesis of glass foamed heat insulating materials based on production wastes from the processing of phosphate ores. The technological process developed yields foamed material with high technical and performance properties and is characterized by absence of energy intensive stages. The foaming temperature equals 250 – 300°C.
