PVC穿線管主要成份為聚氯乙烯，加入其他成分來增強其耐熱性、韌性、延展性的一種材料。PVC可分為軟PVC和硬PVC。其中硬PVC大約占市場的2/3，軟PVC占1/3。軟PVC一般用于地板、天花板以及皮革的表層，但由于軟PVC中含有增塑劑（這也是軟PVC與硬PVC的區(qū)別），物理性能較差（如上水管需要承受一定水壓，軟質(zhì)PVC就不適合使用），所以其使用范圍受到了局限。硬PVC不含增塑劑，因此易成型，物理性能佳，因此具有很大的開發(fā)應(yīng)用價值。聚氯乙烯材料生產(chǎn)過程中，勢必添加幾種助劑，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑。 </p><p> 一、電線管套作用1、方便以后能把電線抽出來如果把電線直接埋進水泥砂漿里，這就成了“死線”，后期如果要進行線路維護、更換和家庭智能化設(shè)備等，就不可能了。小編不否認(rèn)現(xiàn)在多數(shù)家里的裝修，盡管使用了穿線管，但還是做成了“死線”，根本抽出來，但如果不這樣做，可能永遠(yuǎn)也抽不出來。2、保護電線的絕緣層如果直接埋進水泥砂漿中，水泥里的硅酸鹽可能會腐蝕電線的絕緣層，導(dǎo)致電線絕緣下降而造成短路，而且一旦受潮，漏電的現(xiàn)象就難以避免。電線護套管，是一種絕緣保護套管，用于電線電纜外部的保護。</p><div

1、強度高、剛度高。用在行車道下直埋無需加混凝土保護層，能輥快電纜工程建設(shè)進度。2、管材有柔性，能抵御外界重壓和基礎(chǔ)沉降所引起的破壞。3、耐腐蝕，使用壽命長，可在潮濕鹽堿地帶使用。4、阻燃、耐熱性好，可在130度高溫下長期使用而不變形，遇火不燃燒。5、內(nèi)壁光滑，不刮傷電纜。設(shè)計采用承插式的連接方式，方便安裝連接。接頭處加橡膠密封圈封既適應(yīng)熱脹冷縮，又防止泥砂進入。家裝電線套管一般使用PVC管。電線套管主要是考慮電線的絕緣、防潮、防腐和保持通暢等性能?，F(xiàn)在**常見、**安全可行的一種線管是PVC管,但對于不能開槽的承重墻和橫梁等位置,不能使用PVC管,要使用軟管,才不會影響承重墻和橫梁的結(jié)構(gòu)。在穿用電線時輕松，不損傷電線。搬、運要比金屬鋼管和水泥管輕松、方便。四川川路塑膠pvc電線套管</p><p
