Industry of building materials

As a result of the systematic implementation of the event to increase the technical level of production in recent years, high -quality shifts have occurred on the scale of use of advanced equipment and technology in a number of industries of building materials. For example, 23% of sheet glass, including all polished and 9, 8% of the window, is produced according to progressive new technology on the melt of the metal; The lines of horizontal hardening of flat glass are 47, 9% of the corresponding capacities; The release of a heat -shielding glass on new technological lines reached 92, 6% of the total production. The release of ceramic tiles on the flow of automated lines exceeded 90% of the total production. According to cutting technology, 61, 5% of cellular -concrete products are produced on high -performance lines. More than 40% cement is crushed in high -performance mills. The release of long -dimensional asbestos -cement pipes on automated lines reached 29.5% of the total volume of pipes, the production of four -meter pipes on progressive equipment in the volume of small diameter pipes was 52, 6%. In the production of Santechor equipment and products, the use of a hydromechanical method of manufacturing boiler rods was 22%; Bath molding on cars F-88 and F-89 reaches 8, 2%. The use of progressive processes and equipment in galvanic production increases, automatic galvanic lines provide 50% of production. Directions of development of technology and technology for the production of building materials in the USSR, in general, correspond to world trends. The main of these is currently a transition to resource -saving technologies, and we are talking about all types of resources: fuel, electricity, other types of energy, raw materials and materials, production areas, labor resources, environment. Thus, in industrialized countries, new ones are intensively developing, well-known fuel and energy-economic processes are being improved and significant: a dry method of cement production, especially the scheme with the decarbonizers and the use of various processes, mineralizers, and super-plasticizers; closed schemes for grinding materials and t.
