<div id="bgkwxgg" class="xypg-detail-info-bar"> 時(shí)間：2023-03-13 訪(fǎng)問(wèn)量：689 </div> <div id="p8yg9u8" class="news_info_mm"> <p>我們在進(jìn)行水電改造的時(shí)候，一般會(huì )使用pvc排水管，來(lái)負責空間排水的布線(xiàn)鋪設。那么pvc排水管相對于其他排水管來(lái)說(shuō)都有哪些優(yōu)勢呢？</p><p>1、管材表面硬度和抗拉強度優(yōu)，管道安全系數高。</p><p>2、抗老化性好，正常使用壽命長(cháng)。</p><p>3、管道對無(wú)機酸、堿、鹽類(lèi)耐腐蝕性能優(yōu)良，適用于工業(yè)污水排放及輸送。</p><p>4、管道摩阻系數小，水流順暢，不易堵塞，養護工作量少。</p><p>5、材料氧指數高，具有自熄性。</p><p>6、管道線(xiàn)膨脹系數小，為0.07mm/℃，受溫度影響變形量小。PVC排水管導熱系數和彈性模量小，與鑄鐵排水管相比抗冰凍性能優(yōu)良。</p><p>7、管材、管件連接可采用粘接，施工方法簡(jiǎn)單，操作方便，安裝工效高</p><p>8、具有良好的水密性：PVC-U管材的安裝，不論采用粘接還是橡膠圈連接，均具有良好的水密性。</p><p>PVC排水管化學(xué)性質(zhì)穩定，其機械物理性能使其能正常使用可以使用很長(cháng)時(shí)間，同時(shí)其抗腐蝕、抗老化、耐磨性也使之比排水鑄鐵管、水泥管更能長(cháng)期穩定地使用。</p><p>PVC塑料管件的制作使用了不飽和聚酯樹(shù)脂片狀模壓料(SMC)，其填料是片狀的玻璃纖維氈。</p><p>SMC是玻璃鋼工業(yè)20世紀60年代發(fā)展起來(lái)的新工藝，是以一定比例的樹(shù)脂、填料、增稠劑、潤滑劑、阻聚劑、過(guò)氧化物引發(fā)劑等配成糊狀物，然后浸漬玻璃氈片，兩面再覆以聚乙烯薄膜制成的卷材。</p><p>PVC塑料管件成型時(shí)，按規格要求裁剪和疊合后裝入模具，用高壓法成型。采用SMC成型技術(shù)可以實(shí)現自動(dòng)化、機械化、連續化生產(chǎn)，并可壓制大型制品。</p><p><br/></p>
