簡述pvc管透明管的應(yīng)用知識

文章出處：公司動態(tài) 責任編輯：東莞市聯(lián)臻光電材料有限公司發(fā)表時間：2020-08-15

　　? pvc管為內(nèi)嵌螺旋鋼絲骨架的PVC透明無毒軟管，使用溫度0-+65℃，該產(chǎn)品高彈性，耐磨并有優(yōu)良的耐溶劑性，可用于真空泵農(nóng)業(yè)機械、排灌設(shè)備、石油化工設(shè)備、塑料加工機械及食品衛(wèi)生機械等行業(yè)，很多可能不是很了解透明pvc管，下面簡單介紹下pvc管透明管吧。

在通用樹脂生產(chǎn)中，以pvc樹脂耗乙烯量較低，生產(chǎn)成本也很低，國內(nèi)生產(chǎn)每噸PVC需耗乙烯0.5314噸，而每噸聚乙烯平均耗乙烯1.042噸，國內(nèi)每噸PVC樹脂的乙烯耗量比聚乙烯少消耗約50%。另外，從塑料制品角度看，PVC與各種助劑相容性好，在生產(chǎn)管材中可加入大量低廉的填料，使生產(chǎn)成本大大降低。因此，pvc透明塑料管得到了廣泛的應(yīng)用。

PVC管材與金屬管材相比，生產(chǎn)每立方米PVC和生產(chǎn)每立方米鋼及鋁計算，鋼的能耗為316KJ/m3，鋁的能耗是619KJ /m3，PVC的能耗為70KJ/m3，即鋼的能耗是PVC的4.5倍，鋁的能耗是PVC的8.8倍。而生產(chǎn)PVC管的加工能耗也僅為同口徑金屬管材的三分之一。同時由于PVC管壁光滑，不結(jié)腐蝕瘤，輸水效率高，用于輸液可節(jié)電20%左右。

PVC管材有很好的力學性能，且具備極好的耐腐蝕性，使用過程中重量輕，安裝方便，不需維護，而使用鋼鐵作公用工程的下水管道，在使用過程中由于易腐蝕，一定經(jīng)常涂敷涂料，維護費用高。

一般建筑及公用工程用金屬管道20年左右就需更換，而作用加工良好的PVC管道，使用壽命長達50年等。因此，PVC管材是一種生產(chǎn)成本低、強度高，耐腐蝕的良好塑料制品。

一般來講，在排污、廢水和通風管道方面，PVC管道比使用鑄鐵管節(jié)約安裝和勞務(wù)費用約16-37%;作導線管比使用金屬導線套管節(jié)約費用 30-33%;而作用氯化聚氯乙烯(PVC)管在冷熱水方面，比使用相同尺寸的銅管節(jié)約費用為23-44%。因此，由于PVC管材的優(yōu)勢，各國均在積極發(fā)展和推廣PVC管材。

硬質(zhì)PVC管材、管件在眾多PVC制品中，在我國呈快速增長之勢，也是各種塑料管道中消費量比較大的品種。我國PVC管材經(jīng)過近幾年的宣傳推廣，特別是國家有關(guān)政策的支持，PVC管材生產(chǎn)和應(yīng)用取得了長足發(fā)展，PVC管材產(chǎn)量已占塑料管材總產(chǎn)量的50%以上，廣泛應(yīng)用于工業(yè)、建筑、農(nóng)業(yè)等許多行業(yè)。
