It has the advantages of light weight, low thermal conductivity, low water absorption, water resistance, aging resistance, low temperature resistance, easy processing, low price and good quality. Now it has been widely used in the construction market.
Cement polystyrene board is a new type of thermal insulation material, which is made of crushed polystyrene foam scraps or waste polystyrene foam, mixed with cement, water, EC foaming agent and foam stabilizer, stirred, molded and cured. It has the advantages of light weight, low thermal conductivity, good thermal insulation performance, certain strength and toughness, water resistance, flame retardancy, convenient construction, firm pasting, convenient plastering and low price.
Silicate composite thermal insulation mortar is a new type of wall thermal insulation material, which is a gray-white viscous slurry with selected sepiolite and aluminum silicate fiber as the main raw materials, supplemented by a variety of high-quality lightweight inorganic minerals as fillers, and under the action of various additives, it is deeply compounded by various processes such as fibrillation, diffusion expansion, miscibility and bonding. The remarkable characteristics of this material are: good thermal insulation performance, simple construction (direct painting), and solving the cracking phenomenon of the overlay at the joint of the plate. Silicate composite thermal insulation mortar has been listed as the key development object of new thermal insulation materials and products by the state.
