透明管、彈簧冷彎會不會發(fā)白？

文章出處：常見問題責(zé)任編輯：東莞市聯(lián)臻光電材料有限公司發(fā)表時間：2020-08-03

　　? 電工在線管布線的過程中，需要把彈簧放入線管內(nèi)，耗費一定的人力，才能彎到一定的角度，普通的紅藍(lán)線管在人工彎管過程中，線管組織拉伸，導(dǎo)致組織受損發(fā)白，縮短線管使用壽命，易漏電，給業(yè)主的用電安全帶了隱患，透明管是一種純PVC材質(zhì)，不添加雜料或填充料，韌性相對普通紅藍(lán)性管要高，在彈簧冷彎過種，可以做到不發(fā)白、定型好、不回彈等。

為什么市面上的透明線管彈簧冷彎會出現(xiàn)發(fā)白現(xiàn)象呢？這跟透明線管生產(chǎn)商的工藝技術(shù)、還有選用彎管的彈簧質(zhì)量、規(guī)格和彎管的方法都會有一定的關(guān)系。

透明塑料管材質(zhì)一般是以塑料樹脂為原料、加入穩(wěn)定劑、潤滑劑等，以塑的方法在制管機內(nèi)經(jīng)擠壓加工而成。由于它具有質(zhì)輕、耐腐蝕、外形美觀、無不良?xì)馕丁⒓庸と菀?、施工方便等特點。
在建筑工程中獲得了越來越廣泛的應(yīng)用。主要用作房屋建筑的自來水供水系統(tǒng)配管、排水、排氣和排污衛(wèi)生管、地下排水管系統(tǒng)、雨水管以及電線安裝配套用的穿線管等等。是一種以聚氯乙烯(PVC)樹脂為原料，不含增塑劑的塑料管材。HDPE(高密度聚乙烯)是一種結(jié)晶度高、非極性的熱塑性樹脂。其中，UPVC 抗腐蝕能力強，易于連接，價廉，質(zhì)地堅硬。不適用于熱水輸送，接頭粘合技術(shù)要求高，固化時間較長。 HDPE 質(zhì)輕，較好的疲勞強度，耐溫度性能較好，韌性好，可撓性好。
