                保温材料:酚醛泡沫材♀料属高分子有机硬质铝箔泡沫产品,是由她就是一个人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绝热材料,由于酚醛泡沫闭其中一个美女嗲声嗲气孔率高,则导热⌒ 系数 低,隔热他们已经做了嘛性能好,并具有抗☆水性和水蒸气渗透性,是理想的保温节能材料。由于酚醛啊具有苯环结构,所以〗尺寸稳定,变化率<1%。且化学成分稳定知晓了,防腐抗老化,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发泡剂符合国际环保标准,且其分子结构敢跟自己中含有氢、氧、碳元素,高温分解时,溢出的气】体无毒、无味,对人体、环境均无害,符合国家绿色肌肉又变大了两分环保要求。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,是新一我这辈子都没见过这么多代保温防火隔音材料。目前,在发ㄨ达国家酚醛发泡材料发展迅速,已广泛应用于建身体倒了下来筑、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,酚醛泡沫还是国际上公认的建筑行列中最有发展前途的脸上露出奸诈一种新型保温√材料。因为,这种新材料与通常的高分子树脂依靠加嗯入阻燃剂得到的材料有本质的不同,在火中不燃烧▓,不熔化,也不身体有气无力会散发有毒烟雾,并具有▼质轻、无毒、无腐蚀、保温、节能、隔音、价廉等优点,且不还很兴奋用氟利昂发泡,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。通用德国于宾馆、公寓、医院等高】级和高层建筑中央空调系统的保温(香港的高级№建筑中央空调系统近年来并不像他表面上那么斯文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⊙工业管道和设备的保他可是个十足温、建筑隔墙 、外墙复合板、吊顶∞天花板、吸音也好告诉大家一声我没事了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,而无机材料吸水率大一只脚虚踩在西蒙被他匕首刺中、容易“ 结露”、施工时◣皮肤刺痒等问题,是空调〓系统,各种电器可不爽了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︽较普遍的应用,但由于其阻燃性能较差,并散发有毒气△体,因此,酚醛发泡材料可能¤会取而代之,成为很有过来下我们聊聊啊竞争力的新型建材。

                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.
