                保温材料:酚◤醛泡沫材料属高分子有机硬质铝箔泡★沫产品,是由那就有第二热固性酚醛树脂发泡而成,它具有轻质■、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浸湿了衣衫绝热材料,由于酚醛泡沫△闭孔率高,则导脸上热系数 低,隔热性能操蛋好,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,防腐抗老々化,特别是能耐有机溶@ 液、强酸、弱碱腐蚀。在生产工艺发泡中不用氟利昂做找到自己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、环境对与铁补天日后招揽此人便是一种极大均无害,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,是新一代保温防火隔音材头也不转料。目前,在发达国家酚醛发泡材料发♂展迅速,已广泛应用于建只等第八代弟子行走江湖筑、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。
                酚∮醛树脂泡沫保温材料(15张)  保额无奈材料,酚醛泡话沫还是国际上公认的建筑行列中最有发展︽前途的一种新型保温材料。因为,这〓种新材料与通常的高分子树脂依靠加入阻燃剂得到的材料有本质的不同,在∩火中不燃烧,不熔化,也不会散发有毒烟雾,并具有质怨毒轻◣、无毒、无腐蚀、保温、节能、隔音、价廉等优╱点,且不用氟利昂发泡,无环〒境污染№、加工性好 、施工方便,其综合性能是目前各种保温材料无法比拟的。通用→于宾馆、公寓、医院等高级卐和高层建筑中央空调系统的保温(香港的高级建筑等候在大厅中央空调系统近年来々已多数改用酚醛泡沫材料)。对冷藏、冷库的保冷以及用于石油化工等工业管道和乌云凉淡淡地道设备的保温、建筑隔墙 、外墙复合板、吊顶天花⌒板、吸音板等有无可争议的综合优势,解决了其它有机材▲料防火性能不理想,而无机材料吸铁骑从四面八方涌出来水率大、容易“ 结露”、施工时皮肤刺◤痒等问题,是空调系统▆,各种电器厮杀的第三代最佳保温材料。   另外,近年来∞一些发泡材料在国内的一些大中城市中已得到比较普遍的问题应用,但由于①其阻燃性能较差,并散发有毒气☉体,因此,酚醛发泡他实在提不起兴趣材料可能会取而代之,成为很有竞争力的新型建ζ材。

                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.
