酚醛保温板是由酚醛泡沫制成,其主要成分为苯酚和甲醛,酚醛泡沫是一种新型难燃、防火低烟保温材料(限定条件下),它是由酚醛树脂加入发泡剂、固化剂及其它助剂制成的闭孔硬质泡沫塑料。
应用领域
酚醛保温板不仅可以用于建筑外墙外保温系统,还可以应用于活动房、净化车间、冷库彩钢夹芯板,空调风管、管道保温、幕墙保温、屋顶隔热、机房机柜保温、设备保温、碳晶电热板保温及各种需要保温隔热的领域。
酚醛保温板性能特点
它最突出的特点是不燃、低烟、抗高温歧变。它克服了原有泡沫塑料型保温材料易燃、多烟、遇热变形的缺点,保留了原有泡沫塑料型保温材料质轻、施工方便等特点。
1)防火性能优异
保温层采用酚醛泡沫,并与其他材料复合用于建筑保温,基本可以达到国家防火标准B1级,从根本上杜绝外保温火灾发生的可能性,使用温度范围为-250℃~+150℃。
2)保温节能效果突出
酚醛保温板具有良好的保温隔热性能,其导热系数约为0.023W/(m·k),远远低于市场上常用的无机、有机外墙保温产品,可以达到更高的节能效果。
3)质轻、不吸水
酚醛保温板质量轻,容重一般为30—80Kg/m³。同时酚醛保温板不吸水,不怕雨淋。
4)安全环保
酚醛保温板为环保绿色产品,不会刺激皮肤,不会对人体造成任何伤害,燃烧时无毒烟释放(限定条件下,超过燃烧限定值释放甲醛、一氧化碳等)。
5)尺寸稳定性好
酚醛保温板具有非常好的尺寸稳定性,无论在什么环境下,均不会出现收缩、变形等情况。
酚醛泡沫的导热系数在0.023左右(约是聚苯的1/2,聚苯板的传热系数在0.042左右),防火等级是B1级A2级(可耐150℃高温),同时价格与聚苯乙烯挤塑板差不多。聚苯乙烯泡沫和聚氨酯泡沫都易燃,不耐高温,正受到消防部门的限制使用。酚醛防火保温板可以有效解决建筑防火保温问题,酚醛保温板在高温下不熔滴、不软化、发烟量低,不扩散火焰,耐火焰穿透,防火性能出色,并且具有良好的保温节能效果,将优异的防火性能与良好的节能效果集于一身,适合于外墙外保温。
酚醛保温板应用形式:
建筑外墙外保温(薄抹灰系统、保温装饰一体化、幕墙系统)
中央空调复合风管保温(钢面型酚醛复合风管、双面铝箔酚醛复合风管)
彩钢夹芯板领域(活动板房、净化工程、洁净车间、冷库、机柜机房等)
屋顶隔热保温(住宅屋顶、厂房屋顶、屋顶隔热砖)
低温深冷管道保温(LNG管道、液化天然气管道、冷热水管道)
其他各种需要隔热保温的领域
90年代以来酚醛泡沫材料得到很大发展,首先受到英美军方的重视,用之于航天航空、国防军工领域,后又被应用于民用飞机、船舶、车站、油井等防火要求严格的场所,并逐步推向高层建筑、医院、体育设施等领域。

的人走到生命的尽头时,他一定会后悔他的生命仅仅只属于他自己。 人都是要死的,都会归于泥土,只有生是丰富多彩的,生也因此可贵,值得珍惜。而生的贵贱差别却在于对死的解读。 高贵的人面对死亡不是恐惧,而是自责,却死得安详;卑贱的人面对死亡是恐惧,而不是自责,却死得凄凉。 那一月,我摇动所有的经筒,不为超度
