阻氧型地面辐射供暖管能阻隔氧气渗入管道系统，防止供暖系统内的金属部分腐蚀生锈，大大延长了整个供暖系统中金属阀门、开关、锅炉、分集水器等金属件的使用寿命。如果阻氧管使用在自来水方面，即使水长期不流动也不会因氧化而变质，同时靠氧气生存的细菌也无法滋生。

The oxygen-blocking ground radiant heating pipe can block oxygen infiltration into the piping system, prevent the corrosion and rust of the metal part of the heating system, and greatly extend the service life of metal parts such as metal valves, switches, boilers and water collectors in the whole heating system. If oxygen blocking tube is used in tap water, even if the water does not flow for a long time, it will not deterio- rate due to oxidation, and bacteria that live on oxygen can not breed.

PE-RT 五层阻氧管

EVOH树脂为半结晶性热塑性树脂化学结构和分子结构，其分子中含有羟基分子和分子间氢键彼此强烈的键合，使氧气扩散所需的链段运动受分子内和分子间内聚能限制，分子链柔性小，分子间自由运动暂时形成空间几率小，氧气渗透率为0.1/m³，d40℃，对氧的阻隔性比PE高10000倍。

EVOH resin is a semi-crystalline thermoplastic resin with chemical structure and molecular structure. Its molecules contain hydroxyl molecules and intermolecular hydrogen bonds strongly bonded to each other, so that the chain movement required by oxygen diffusion is limited by intramolecular and intermolecular cohesion energy. The molecular chain flexibility is small, and the free intermolecular movement is less likely to temporarily form space, oxygen permeability is 0.1/m³, d, 40℃, The oxygen barrier is 10000 times higher than PE.

EVOH结晶度高，耐热性能好，在长期供热过程中性能不会降低。

阻氧管道通过国际一流的多层复合技术，配合严密而精细的控制，确保管材各层壁厚均匀，任何部位的氧气渗透率都小于0.1/m³，d，40℃。

EVOH crystallinity is high, heat resistance is good, in the long-term heating process performance will not be reduced.

Oxygen blocking pipe through the international first-class multi-layer composite technology, with strict and fine control, to ensure that the wall

thickness of each layer of the pipe is uniform, any part of the oxygen permeability is less than 0.1/m³, d, 40℃.
