折疊發(fā)展趨勢(shì)PVC管道憑借其自重輕，耐腐蝕，耐壓強(qiáng)度高，安全方便等特點(diǎn)受到了工程界的一直好評(píng)。近些年來，在國內(nèi)經(jīng)濟(jì)快速發(fā)展的拉動(dòng)下，我國PVC管道發(fā)展十分迅速。 </p> <p> 行業(yè)分析師指出:受PVC完善的配套產(chǎn)業(yè)鏈以及國產(chǎn)原料支撐，2010年P(guān)VC管道產(chǎn)量占到了總量的55%。近些年，PVC管道市場受到各種因素的影響其市場份額在不斷的下降。而PVC管道市場份額下降主要有三大方面: </p> <p> 一是:PVC管道市場受到PE、PPR等其他塑料管道的沖擊，被搶占了一定的市場份額; </p> <p> 二是:含鉛穩(wěn)定劑在與食品類產(chǎn)品接觸的PVC管材中的禁用，對(duì)PVC管道的發(fā)展有一定的負(fù)面影響; </p> <p> 三是:當(dāng)前，PVC管道發(fā)展處于高速發(fā)展期，行業(yè)產(chǎn)能不斷擴(kuò)張，很多中小型企業(yè)為搶占市場，降低成本，在配方中大量填充碳酸鈣，以次充好，影響了PVC管道整個(gè)行業(yè)的形象，直接影響了PVC市場份額，加速了PVC市場份額的流失。 </p> <p> 但整體來看，雖然PVC管道份額在減少，但仍占據(jù)著塑料管道市場的霸主地位。并且塑料管道行業(yè)的誘人前景，仍是帶動(dòng)PVC管道行業(yè)發(fā)展的一大亮點(diǎn)。 </p><p> 折疊尺寸規(guī)格硬PVC管有公稱外徑為50CM的,但是軟PVC管比較大的一般是50mm的。 </p> <p> 硬PVC管規(guī)格:GB/T13020-1991 </p> <p>

</p> <p> 作為科技發(fā)展的產(chǎn)物之一，PVC管材在日常生活中觸目可及。在歐洲，1980年-1990年塑料管的增長率為8%，2001年產(chǎn)量達(dá)350萬噸，其中PVC管占60%。美國1985年塑料管產(chǎn)量為160萬噸，1999年產(chǎn)量約360萬噸，其中，PVC管占78%。而中國的***根UPVV擴(kuò)口管材是于1983年在沈陽塑料廠誕生的，此后，中國大陸具備了PVC管、排水管的生產(chǎn)能力。二十世紀(jì)90年代后期是中國大陸PVC管道的高速發(fā)展時(shí)期。期間一些年產(chǎn)能在5萬噸以上的工廠陸續(xù)建成投產(chǎn)，萬噸以上生產(chǎn)規(guī)模的PVC管道工廠達(dá)30多家。塑料管道的年生產(chǎn)能力為200萬噸。日豐產(chǎn)品涵蓋給水、供暖、燃?xì)獾葢?yīng)用領(lǐng)域，并在立足新型管道行業(yè)的同時(shí)，致力拓展水暖衛(wèi)浴。成都穿線管日豐定制</p><p style="text-indent:25px">燕尾槽結(jié)構(gòu):不論熱脹冷縮，始終緊密結(jié)合，確保密封性能。成都PPR日豐總經(jīng)銷</p><p> 塑料管UPVC 管 </p> <p> 實(shí)際上就是一種塑料管，接口處一般用膠粘接，UPVC管的抗凍和耐熱能力都不好。所以冷熱水管都很少用，PVC管適用于電線管道和排污管道，科技界發(fā)現(xiàn)，能使PVC變得更為柔軟的化學(xué)添加劑酞，對(duì)人體內(nèi)腎、肝、睪丸影響甚大，會(huì)導(dǎo)致**、腎損壞，破壞人體功能再造系統(tǒng)，影響發(fā)育(只能用冷水不好用熱水，而且冬天及容易脆)。 </p> <p> PPR 管 </p> <p> 作為一種新型的水管材料，它既可以用作冷管，也可以用作熱水管，由于其***、質(zhì)輕、耐壓、耐腐蝕，正在成為一種推廣的材料。也適用于熱水管道，甚至純凈飲用水管道。PPR管的接口采用熱熔技術(shù)，管子之間完全融合到了一起，所以一旦安裝打壓測(cè)試通過，不會(huì)像鋁塑管一樣存在時(shí)間長了老化漏水現(xiàn)象，而且PPR管不會(huì)結(jié)垢。PPR水管的主要缺點(diǎn)是:耐高溫性，耐壓性稍差些，長期工作溫度不能超過70℃;線膨脹系數(shù)大，通熱水后管材容易變形，影響美觀;每段長度直管為4米/根，盤管為100米---300米不等。且不能小角度施工，如果管道鋪設(shè)距離長或者轉(zhuǎn)角處(小角度)多，在施工中就要用到大量接頭;管材便宜但配件價(jià)格相對(duì)較高。成都PPR日豐總經(jīng)銷</p></p><br
