</p> <p> 而給水用pe管材的國(guó)際標(biāo)準(zhǔn)(ISO4427)直到1996年才正式發(fā)布。我國(guó)于1999年參照ISO4427編寫(xiě)了國(guó)家標(biāo)準(zhǔn)GB/T13663，并在2000年發(fā)布實(shí)施，但至今pe管件的標(biāo)準(zhǔn)、工程技術(shù)規(guī)范等仍在繼續(xù)完善之中。這說(shuō)明國(guó)內(nèi)pe管材質(zhì)量還未穩(wěn)定，成都HDPE日豐定制廠家，管材管件配套未完善，因而無(wú)法確保生產(chǎn)、施工中的質(zhì)量，成都HDPE日豐定制廠家。產(chǎn)品彰顯整體性、專業(yè)性、人性化，以環(huán)保，成都HDPE日豐定制廠家、節(jié)能的優(yōu)越性能，將生態(tài)、建筑與人完美融合，實(shí)現(xiàn)全程生態(tài)把控.成都HDPE日豐定制廠家</p><div

前景展望中國(guó)塑料管道生產(chǎn)能力達(dá)300萬(wàn)噸，主要有PVC、PE和PP-R管道三大類，其中PVC管道是市場(chǎng)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(wàn)噸以上，2003年P(guān)VC管道(管件)年產(chǎn)量達(dá)120多萬(wàn)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(jìn)入這個(gè)行業(yè)投資，但在國(guó)內(nèi)生產(chǎn)眾多廠家(2000多家)中，年產(chǎn)能力在1萬(wàn)噸的*有70多家，年產(chǎn)3萬(wàn)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(guó)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(shí)大量的非標(biāo)管仍充斥市場(chǎng)，導(dǎo)致市場(chǎng)競(jìng)爭(zhēng)無(wú)序而混亂。 </p> <p> <br /> </p> <p> <br /> </p><p> 管道壓力規(guī)定(1)PVC給水管道所示的壓力均表示為公稱壓力，用Mpa表示，1Mpa≈10kgf/cm2即管材在20℃條件下，輸送介質(zhì)的工作壓力。但隨著介質(zhì)的溫度的升高(不得輸送>50℃的介質(zhì))工作壓力隨之減小，這從客觀上在選擇給水管道須考慮足夠的壓力的安全系數(shù) </p> <p> (2)給水管材的公稱壓力規(guī)定為:0.6Mpa、0.8Mpa、1.0Mpa、1.25Mpa、1.6Mpa等5種。 </p> <p> (3)同等規(guī)格管材的公稱壓力的大小一般以管材的壁厚來(lái)劃分。 </p> <p> (4)每個(gè)壓力區(qū)的**小口徑的管材規(guī)定為:0.6Mpa管材的**小口徑為63mm，0.8Mpa管材的**小口徑為50mm，1.0Mpa管材的**小口徑為40mm，1.25Mpa管材的**小口徑為32mm，1.6Mpa管材的**小口徑為20mm和25mm。 </p> <p> (5)給水管材的公稱壓力一般為1.6Mpa，且與各種壓力的管材相配套。折疊日豐人的足跡遍布全國(guó)30座城市,為近70名家庭貧困卻堅(jiān)持著大學(xué)夢(mèng)想的***學(xué)子,帶去愛(ài)和希望。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

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(zhǎng)率為8%，2001年產(chǎn)量達(dá)350萬(wàn)噸，其中PVC管占60%。美國(guó)1985年塑料管產(chǎn)量為160萬(wàn)噸，1999年產(chǎn)量約360萬(wàn)噸，其中，PVC管占78%。而中國(guó)的***根UPVV擴(kuò)口管材是于1983年在沈陽(yáng)塑料廠誕生的，此后，中國(guó)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(guó)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(wàn)噸以上的工廠陸續(xù)建成投產(chǎn)，萬(wàn)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(wàn)噸。用于民用建筑、市政工程、給水、排污、通信、電力、燃?xì)?、農(nóng)飲農(nóng)灌、精品家裝、門(mén)窗型材等領(lǐng)域.四川CPVC日豐代理商</p><p

對(duì)于走在頂上的電源線必須穿線管而過(guò)，而且對(duì)吊頂?shù)哪君埞且M(jìn)行防火、防蟲(chóng)等兩項(xiàng)處理，以免日后給業(yè)主帶來(lái)麻煩。首先選擇電線時(shí)要用銅線，忌用鋁線。由于鋁線的導(dǎo)電性差，通電過(guò)程中電線容易發(fā)熱甚至引發(fā)火災(zāi)。然后，布線一定要用絕緣的穿線管。[3] </p> <p> 如果將電線直接藏在墻內(nèi)，等于家里潛伏著一顆定時(shí)，隨時(shí)都可能漏電，發(fā)生險(xiǎn)情。當(dāng)然，各種不同的線路也***不能走同一管線，比如電視天線，電話線等等。 </p> <p> 線路接頭不能過(guò)多，如果必須接線，要做好絕緣及防潮，如果條件允許還可以"涮錫"。裝修結(jié)束時(shí)，業(yè)主必須索要電路圖，這樣有助于預(yù)防電路系統(tǒng)***發(fā)生，另外將來(lái)升級(jí)改造都用得上。 </p> <p> 電線埋墻必需穿線管，一般可選的有金屬穿線管和PVC穿線管兩種:金屬穿線管比較貴，但抗干擾性能強(qiáng)于PVC穿線管，不怕火，日后對(duì)電線的保護(hù)性也會(huì)強(qiáng)于PVC穿線管(比如使用PVC穿線管可能在以后往墻上釘釘子的時(shí)候不小心打穿)。PVC穿線管價(jià)格實(shí)惠，拐彎比金屬管容易，絕緣性能好。只是要選擇結(jié)實(shí)的，穿線管簡(jiǎn)單方法就是用腳踩一下，不會(huì)被踩癟的就是好的。成都HDPE日豐定制廠家</p><p
