Incombustible heat preservation material application is more and more widely
As frequent fire to people knocking on alarm, incombustible insulation materials such as foam glass and rock wool board, etc., more and more widely applied in practice. And now, not only widely used in building energy efficiency, these incombustible insulation materials are also popular in other areas.
Recently, the Shanghai hudong zhonghua shipyard will homebred incombustible insulation foam glass and rock wool board used in ship refrigeration system, further enhance the ability of ship fire insulation, and at the request of the design achieves the current highest ship rules. At present, the thermal insulation material is generally used to ship refrigeration system mainly polystyrene foamed plastic, polyurethane foam plastics and perfusion spray paint. Although this kind of material thermal conductivity and density is small, and can keep a good cooling effect for a long time. But because they are organic material, thus has flammability, even if the additive into the various kinds of flame retardant, flame retardant, high temperature or fire, still can produce combustion, and at the same time release more smoke and toxic gases, constitutes a threat to human life and property safety. Incombustible insulation foam glass and rock wool products can not only overcome the above shortcomings, and thus expand the range of application of inorganic heat preservation material in China. Noncombustible heat preservation material can be according to the characteristics of the refrigeration system. According to the use of different parts, respectively applied at the top of the floor, bulkhead and wall, etc. Corresponding selection on the floor with a high compressive strength, water vapor permeability of zero foam glass, at the top of the bulkhead and the walls of the corresponding rock wool board. Both products density can be achieved respectively 160 and 10, 20 and 160 with the federal republic of Germany SBG classification society certificate of recognition. The scope of application of expanding domestic noncombustible heat preservation material, produced good economic benefit.
Noncombustible heat preservation material, therefore, not only will be increasingly used in the structure of the insulation system, and constantly extend to other areas. The production foreground is very good.
