pp阻燃风管刚度、承压、耐温性能怎么样
How about the rigidity, pressure and temperature resistance of PP Flame Retardant air duct
pp阻燃风管的原料是pps树脂，通过高温加热、压力挤出等流程加工为成品。因为原料是比较稳定的纯净的聚合物，因而板材本身的性能也是比较稳定的。由于pps的化学惰性，它几乎不与任何介质发生反应。但是我们依然需要了解详细的化学***性，以推广到更多的应用***域。
The raw material of PP flame-retardant air duct is PPS resin, which is processed into finished product through high temperature heating, pressure extrusion and other processes. Because the raw material is relatively stable and pure polymer, the performance of the plate itself is relatively stable. Due to the chemical inertness of PPS, it hardly reacts with any medium. However, we still need to know the detailed chemical characteristics to promote to more application fields.
1、******的刚度和承压能力
1. Good rigidity and bearing capacity
pps板材具有很高的刚度和承压能力，但光滑性和电气***缘性稍逊。它具有低温条件下的高强度和高韧性，pps对氯化物，溴化物以及能量射线均可保持稳定。高温时酯和酮溶液均可对其造成侵蚀。
PPS plate has high stiffness and bearing capacity, but its smoothness and electrical insulation are slightly inferior. It has high strength and toughness at low temperature. PPS is stable for chloride, bromide and energy ray. The solution of ester and ketone can corrode it at high temperature.
2、耐温***性***
2. Good temperature resistance
pps板材耐温高，******的抗化学腐蚀及抗水解性能，突出的抗紫外线和耐气候性能。机械强度高、刚性***、耐蠕变性能***、******的滑动性和耐磨性能、固有的低可燃性，电***缘性能***。
PPS plate has high temperature resistance, excellent chemical corrosion resistance and hydrolysis resistance, outstanding UV resistance and weather resistance. High mechanical strength, good rigidity, good creep resistance, good sliding and wear resistance, inherent low flammability, good electrical insulation.
除此之外，pps板材也具有一些劣势，如燃烧时含有氟的烟，不易粘接等，但依然不妨碍它的广泛应用。并将有着更加广阔的应用天地。
In addition, PPS board also has some disadvantages, such as the smoke containing fluorine when burning, not easy to bond, etc., but it still does not hinder its wide application. And will have a broader application of the world.
