冷热水用聚丁烯(pb)管材-凯发88

聚丁烯(pb)是一种高分子惰性聚合物,由于其分子结构的稳定性,与同是烯烃类材料的聚乙烯(pe)和聚丙烯(pp)相比,材料性能更加稳定,具有更高的耐热强度、更高的抗蠕变性能、更好的化学稳定性和抗低温脆性的特点,适用于标准要求的建筑热水及采暖系统。

产品种类:

pb管材、pvc管件、pvc管材、pvc线盒、奥州管、泰立管、pe-rt地暖管、ppr给水管材管件、pvc排水管材管件、pvc电工套管

产品说明

  产品介绍

  聚丁烯(pb)是一种高分子惰性聚合物,由于其分子结构的稳定性,与同是烯烃类材料的聚乙烯(pe)和聚丙烯(pp)相比,材料性能稳定,具有较高的耐热强度、较高的抗蠕变性能、较好的化学稳定性和抗低温脆性的特点,适用于标准要求的建筑热水及采暖系统。

  主要优点

  1、重量轻,柔软性好,施工简单,易于搬运。

  2、耐久性能好,无毒无害,不发生化学反应。

  3、抗紫外线、耐腐蚀,pb管抗紫外线和微生物侵害。

  4、抗冻耐热性好:在- 20°c的情况下,具有较好的低温抗冲击性能,可耐100℃以下的高温。

  5、管壁光滑,不结垢。

  6、热伸缩性好,连接方式先进,膨胀系数与混凝土相近。

  7、节约能源: pb管用于低温地面辐射采暖时,可节省能源30%。

  8、易于维修、改造: pb管暗埋时,不与混凝土粘接。

  应用范围

  给水(卫生管)及热水管:在自来水及热水管道方面,pb管是公认的无毒、无味及耐用的管道。供暖用管:pb管保温性能良好,施工方便。适合用在新建、扩建、改建民用及工业建筑物低温地板辐射采暖的使用。

  空调、工业用管: pb管耐腐蚀性(抗酸碱盐性)强,无毒无味,是化工、食品加工、综合医院、工业用水等方面的较好选择。
