PVC塑料管除了它的经济性外,还有良好的耐化学性能、易加工性和自熄性。其内表光滑,介质的流动阻力小,但它也有耐冲击性能低、蠕变性能差和耐热性低等缺点,所以它的应用范围受到了一定限制。PVC—FRP组成的复合塑料管,充分发挥了PVC和FRP两者的长处,是一种既经济、结构又合理的耐压耐腐蚀管道。 PVC—FRP复合塑料管的质量与PVC—FRP之间粘合剂性能、工艺制造过程的条件等密切相关。
PVC plastic pipe in addition to its economy, but also good chemical resistance, ease of processing and self-extinguishing. Its internal surface is smooth, the flow resistance of the medium is small, but it also has low impact resistance, poor creep properties and low heat resistance, so its application has been subject to certain restrictions. PVC-FRP composite plastic pipe, give full play to the advantages of both PVC and FRP, is an economical, structural and reasonable pressure resistant corrosion-resistant pipe. The quality of PVC-FRP composite plastic pipe is closely related to the adhesive performance between PVC-FRP and the conditions of the process manufacturing process.
