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試通過，不會像鋁塑管一樣存在時間長了老化漏水現(xiàn)象，而且PPR管不會結(jié)垢。PPR水管的主要缺點是: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，成都排水管日豐定制廠家，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;管材便宜但配件價格相對較高，成都排水管日豐定制廠家。

前景展望中國塑料管道生產(chǎn)能力達300萬噸，主要有PVC、PE和PP-R管道三大類，其中PVC管道是市場份額比較大的塑料管道，占塑料管道近70%的份額。PVC管材生產(chǎn)線1600余條。年生產(chǎn)能力250萬噸以上，2003年P(guān)VC管道(管件)年產(chǎn)量達120多萬噸。在塑料管道中，PVC的份額為70%， PE占25%， PP-R占4%，其它占1%。 </p> <p> 雖然PVC管道的快速發(fā)展吸引眾多企業(yè)進入這個行業(yè)投資，但在國內(nèi)生產(chǎn)眾多廠家(2000多家)中，年產(chǎn)能力在1萬噸的*有70多家，年產(chǎn)3萬噸以上的企業(yè)為20多家并擁有行業(yè)60%的產(chǎn)量。 </p> <p> 整體而言，國內(nèi)小口徑、低附加值的管道企業(yè)多，大口徑、高技術(shù)含量的企業(yè)少。PVC管材的加工能力分布存在結(jié)構(gòu)性不合理。中小企業(yè)加工能力主要集中在PVC排水管，同時大量的非標管仍充斥市場，導致市場競爭無序而混亂。 </p> <p> <br /> </p> <p> <br /> </p><p>

PVC穿線管在不同場合該如何正確使用PVC管材的材料學名叫聚氯乙烯,是一種熱塑性樹脂材質(zhì),它有著非常好的機械性能,抗張強度60MPa左右.在制管的過程中添加一些輔助劑會使PVC管材具有難燃,耐酸堿,耐磨的性能,還有對穿線管來說**重要的絕緣性.就是這些優(yōu)異的特點使得PVC穿線管占領(lǐng)了巨大的市場. </p> <p> 不同應用領(lǐng)域要求PVC管有不同的功能,所以PVC穿線管在應用時也會有所不同,下面小編帶大家看看不同場所在使用PVC穿線管的時候怎么使用好. </p> <p> 1、對于暗敷于墻體內(nèi)、埋敷于地下不燃燒體內(nèi)的線管,以及農(nóng)村建筑等普通民房家裝用線管,須采用滿足建設(shè)部標準JG3050-199[1] 8《建筑用絕緣電工套管及配件》的具有一定的阻燃性能,同時滿足物理力學性能要求的PVC穿線管.根據(jù)精細和地方進行. </p> <p> 2、對于火災危險性較高的場所,如賓館、飯店、商場(大型超市)、圖書館、歌舞***所等公眾聚集場所的吊頂及地板內(nèi)的線路進行穿管保護時,因其頂棚地板內(nèi)有較多可燃、易燃材料,應當選用燃燒性能級別較高的阻燃PVC穿線管[2] . </p> <p> <br /> </p> <p> . 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。成都排水管日豐定制廠家</p><p style="text-indent:25px">避免長期紫外線照射，防止過快老化，采用抗紫外線的黑色管或采取其他防護措施(穿套保溫管可以一舉兩得)。成都排水管日豐定制廠家</p><p> 發(fā)展現(xiàn)狀從上個世紀80年代初，國家大力推廣應用upvc管，并制定了一系列的政策、制度、標準，也積累了不少經(jīng)驗。發(fā)展到***，已經(jīng)具備了完善的產(chǎn)品標準、檢測方法標準及檢測手段、施工工程技術(shù)規(guī)范等，從而統(tǒng)一了產(chǎn)品的規(guī)格尺寸和質(zhì)量指標，實現(xiàn)了產(chǎn)品的互換性。這說明了pvc給水管道的發(fā)展已經(jīng)進入了成熟期，產(chǎn)品質(zhì)量和施工質(zhì)量均有了保障，從而保證了pvc給水管道的使用效果。 </p> <p> 而給水用pe管材的國際標準(ISO4427)直到1996年才正式發(fā)布。我國于1999年參照ISO4427編寫了國家標準GB/T13663，并在2000年發(fā)布實施，但至今pe管件的標準、工程技術(shù)規(guī)范等仍在繼續(xù)完善之中。這說明國內(nèi)pe管材質(zhì)量還未穩(wěn)定，管材管件配套未完善，因而無法確保生產(chǎn)、施工中的質(zhì)量。成都排水管日豐定制廠家</p></p><br
