3、pvc管還有一種是排水管，排水管的直徑也是所有pvc管中比較大的，家庭中一般使用160mm以下的就可以，工業(yè)場所的排水管有200mm，250mm，400mm，500mm等尺寸。 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)應用價值。聚氯乙烯材料生產(chǎn)過程中，普洱PVC管材廠家，勢必添加幾種助劑，普洱PVC管材廠家，普洱PVC管材廠家，如穩(wěn)定劑，增塑劑等等，倘若全部采用環(huán)保助劑，那PVC管材亦是無害無味環(huán)保的制品。</p><div

隨著**開放的不斷深入發(fā)展，人們的生活水平不斷提高，對自來水質(zhì)量的要求也越來越高。供水行業(yè)除了保證出廠水符合生活飲用水標準外，還必須使通過管網(wǎng)輸送的水合格。人們對自來水的"黃水""黑水"等現(xiàn)象反映強烈，而導制管網(wǎng)水質(zhì)變差的主要原因是給水管道的銹蝕，特別是冷鍍鋅管，其管內(nèi)壁的鍍層不穩(wěn)定，管使用一年半載不長時間就開始銹蝕，造成水中有鐵腥味和顏色，埋在地下的鍍鋅管銹蝕更為嚴重。而UPVC管耐腐蝕。不結(jié)垢，能控制細菌生長，有利于保護水質(zhì)不受管道的二次污染。所以UPVC管有著較廣的應用前景，尤其是用戶水表前的大量埋地管都可以用它。

Regnault）發(fā)現(xiàn)。隨后在1872年德國的另一位科學家（Eugen Baumann）也發(fā)現(xiàn)了這種新的材料。在當時pvc材料為白色的固體，極具易碎性，并沒有實際的應用性。在20世紀初俄國化學家（Ivan Ostromislensky）和Fritz Klatte 等一批化學人士都曾嘗試改變pvc的易碎性，使其成為商業(yè)產(chǎn)品但是都已失敗而告終。直到在1926年美國的Waldo Semon(B.F. Goodrich公司)的合成了PVC并在美國申請了專利，他通過合成多種添加劑解決了pvc的易碎性，增加了pvc材料產(chǎn)品的拓展性，使其具備了產(chǎn)品商業(yè)化的基礎。1931年德國開始用乳液方法開始生產(chǎn)pvc，1941年美國開始用漂浮法生產(chǎn)pvc，由此pvc材料相關(guān)產(chǎn)品開始大量應用于生產(chǎn)生活應用。隨著科技的的不斷發(fā)展，當下pvc生產(chǎn)合成已經(jīng)被本體合成法取代，使其效率更高，成本也**的降低。</p><div
