保温材料:酚醛泡沫材料属高分子有机硬质铝箔泡沫产①品,是由热固性酚醛树脂发泡而成,它具有轻但是实际上他质、防火、遇明火不【燃烧、无烟、无毒、无滴落,使用温度→围广(-196~+200℃)低温环境下不收缩、不脆化,是暖通制冷↓工程理想的绝热材料,由于酚醛泡沫闭孔率高,则导热系数〖 低,隔热『性能好,并具有抗水性和水蒸气渗透性,是理想的保温节能材⌒ 料。由于酚醛具有苯环结构,所以尺寸■稳定,变化率<1%。且化学成分稳▼定,防腐抗老化,特别是能耐ㄨ有机溶液、强酸、弱碱腐蚀。在生产工艺发泡中不用氟利昂做发泡剂符合国际环保标准,且其♂分子结构中含有氢、氧、碳元素,高温◥分解时,溢出的气体无毒、无味,对人体、环境ぷ均无害,符合国家绿色环保要求。故此,酚醛超级复合板是最理想】的防火、绝热、节能、美观的环保绿色保温∩材料 酚醛泡沫素有“保温材料之@ 王”的美称,是新一代保温情况防火隔音材料。目前,在发达国家酚■醛发泡材料发展迅速,已广泛应▽用于建筑、国防、外贸、贮存、能源等领域。美国︻建设行业所用的隔音保温泡沫塑料中,酚醛材料已占40%;日本也已成立酚醛泡沫普及协会以推□ 广这种新材料。 Phenolic foam insulation materials ( 15 ) phenolic foam or internationally recognized buildings in the ranks of the most promising a new thermal insulation material. Because, this new material and usually polymer resin by adding flame retardant material obtained is essentially different, in a fire is not burning, not melting, also not emit toxic fumes, and has the advantages of light weight, non-toxic, non-corrosive, insulation, energy-saving, sound insulation, the advantages of cheap, and without freon foam, no environment pollution, good processing performance, convenient construction, its comprehensive performance is currently a variety of insulation materials can not match. General hotel, Residence, hospitals and other senior and high-rise building central air conditioning system of thermal insulation ( Hongkong high building central air conditioning system in recent years has had the most to phenolic foam ). On cold storage, cold storage cold and used in petroleum chemical industry pipeline and equipment insulation, building exterior wall composite board, wall, ceiling, and other sound-absorbing plate has undisputed integrated advantage, solved the other organic material fire performance is not ideal, and inorganic materials high water absorption, easy" dew", the construction of the skin is itchy wait for a problem, air-conditioning system, all kinds of electrical appliances in the third generation of the best insulation material. In addition, in recent years a number of foam material in some domestic large and medium-sized city has been more widely, but because of its flame retardant properties is poor, and emit toxic gases, therefore, phenolic foam material may replace sb., become very competitive new building materials. |
