Description

一种无碱长玻纤型PE管增强专用料
技术领域
本发明公开了一种无碱长玻纤型PE管增强专用料,具体为排水管材料技术领域。
背景技术
PE是聚乙烯塑料,最基础的一种塑料,塑料袋、保鲜膜等都是PE,HDPE是一种结晶度高、非极性的热塑性树脂,而利用PE作为原材料,经过挤塑、吹塑、注塑或者滚塑等工艺生产的管件,都可统称为PE管。
世界各国在现代化进程中的历史经验表明,塑料管的发展速度均超过同期经济发展速度,用塑料管代替传统管材是历史发展不可抗拒的趋势。即使在已建成密布塑料管网的发达国家,塑料管的应用量仍在逐年增长,例如1986年欧洲塑料管总用量为213.4万吨,1998年增长到346.5万吨,年均增长率为5.2%,超过同期国民经济增长速度。在过去10年中,中国塑料管市场年均增长率为20%,2000年、2002年及2003年产量分别达到70~80万吨、130万吨及150万吨,增长率为15%,预计2010年前,国内塑料管材年均增长率仍将超过20%,而其中PE管因为具有优良的耐大多数生活和工业用化学品的特性,使用前景更为广阔。
目前现有的PE管,根据使用要求,分别运用于输送气态的人工煤气、天然气、液化石油气等,实际运用中,PE管与钢管比较,施工工艺简单,有一定的柔韧性,更主要的是不用作防腐处理,节省大量的工序,但是PE管的自身存在短板,在面对高燃烧率的气体传输时,自身缺少有效的阻燃效果,会使传输事故恶化,安全性低,且想对于钢管来说,PE管的抗压强度和物理机械性能差,使得PE管的使用范围受限,市场竞争力有待提高。
