Thermal insulation material refers to the material that can block the transfer of heat flow, also known as heat insulation material. As a kind of thermal insulation material, GWH aluminum foil glass fiber cloth has the characteristics of smooth and flat surface, high light reflectivity, resistance to vertical and horizontal expansion, air tightness, water permeability, good sealing and strong weather resistance. Aluminum foil glass fiber cloth has high strength, high surface density, smooth and flat surface. The glass fiber fireproof cloth on the back has good high temperature resistance. The thicker the base cloth on the back, the more significant the flame retardant capacity of the fireproof cloth and the smaller the thermal conductivity. As a thermal insulation material, it is often used in chemical industry, smelting, ship welding Covering effect of electric welding and cutting or enclosure to prevent spark splashing. The surface of aluminum foil glass fiber cloth is relatively smooth and has high light reflectivity. It can be attached to outdoor pipes to prevent the aging of pipes exposed to the outside for a long time. It is used in large-scale pipeline engineering, such as the external binding protection of gas pipes, the protection and thermal insulation of cold and hot water pipes. Due to its stable structure, it is exposed to the outside for a long time, Such as airport shelter, airport ceiling and roof insulation of large factories. At the same time, aluminum foil glass fiber cloth will become very soft after special process treatment, which is easy to process and sew. It can make fire protective clothing, electric welding and welding protective apron, which plays a good protective role. The common specifications of flame retardant and thermal insulation aluminum foil cloth are 1m, 1.2m and 1.5m, with a thickness of 0.1mm-3.0mm. It can be used for a long time in a high temperature environment, not easy to aging and long service time.
