FAQ

Roofing the top of the extruded polystyrene insulation board generally how much weight ah?

Metal hose is an important connection in engineering technology, from the corrugated flexible tube, mesh sets and joints combined. China in 1993 issued a national standard "corrugated metal hose general technical conditions" (GB / T-93). Metal hoses are made of austenitic stainless steel or according to the material required by the user. It has excellent softness, corrosion resistance, high temperature resistance (-235 ℃ ~ + 450 ℃), High pressure (up to 32MPa), in the pipeline can be connected in any direction for temperature compensation and absorption of vibration, reduce noise, change the direction of media transmission, to eliminate the pipe or between the pipe and mechanical displacement between equipment, Lan metal corrugated hose for a displacement, vibration of the various pumps, valves and other flexible joints is particularly applicable. Metal hoses use two kinds of bellows, one is a spiral corrugated tube; the other is a ring bellows. Spiral bellows The spiral bellows is a tubular shell with a corrugated spiral and has a helix angle between adjacent two corrugations. All corrugations can be connected by a helix. Ring bellows Corrugated tube is corrugated closed ring shaped tubular shell, wave and wave from the ring ripple in series. The ring bellows is machined from a seamless pipe or welded pipe. By the processing mode, compared with the spiral corrugated pipe, the length of a single tube is usually shorter. The advantage of the ring bellows is good elasticity and small rigidity. If you need to provide detailed advice, please call 0317-, Xinlong bellows will be happy to serve you.

Panasonic refrigerator with the world's leading vacuum insulation material Vacuuminsulationpanel (referred to as VIP) vacuum insulation board, is developed in recent years, a new type of highly efficient insulation material, which uses vacuum insulation principle, under vacuum conditions, the thermal conductivity is very low , Widely used in household appliances. The product to fill the gaps, is a leading international high-tech products. . VIP in the production and application process does not use ODS substances. . the insulation layer of the same thickness, you can save energy. . the same energy consumption, VIP can reduce the thickness of the insulation layer to reduce the volume of objects, increase storage space. . VIP design engineers can provide a variety of flexible options. . CFC consumption of ozone, destruction of the ecological environment, if the alternative blowing agent, its high thermal conductivity, reducing the thermal insulation properties of the foam, although the environmental protection, but need to consume more energy, and VIP is environmentally friendly And the dual advantages of energy saving. . VIP on environmental protection and national energy conservation has a great contribution. . VIP thermal conductivity is PU one-eighth, is the replacement of insulation materials. Vacuum insulation panel (VIP) technology industry has quickly formed a practical industry trends, and industry-class enterprises to adopt. Was rated as energy-saving refrigerator model products which is the use of VIP technology to achieve energy-saving purposes. (BCD-239DVC), Panasonic "energy saving king" refrigerator (NR-E461U), the new energy-saving "Golden Eagle" refrigerator (BCD-218E) Meiling "digital energy-saving Wang" refrigerator (BCD-239DVC) BCD-200A / HC, BCD-270A / HC and other six models (BCD-219U / C), the best energy-saving refrigerators, including BCD-180A / HC, BCD-200A / HC, BCD-270A / HC and other six models Wait.
