class="title">詳細(xì)說(shuō)明</p><div id="qfmdfme" class="box"><p><p> 高密度聚乙烯(HDPE)具有優(yōu)異的化學(xué)穩(wěn)定性、耐老化及耐環(huán)境應(yīng)力開(kāi)裂的性能。由其為原材料生產(chǎn)出來(lái)的HDPE雙壁波紋管屬于柔性管。其要性能如下: </p> <p> 抗外壓能力強(qiáng) </p> <p> 外壁呈環(huán)形波紋狀結(jié)構(gòu)，**增強(qiáng)了管材的環(huán)剛度，從而增強(qiáng)了管道對(duì)土壤負(fù)荷的抵抗力，在這個(gè)性能方面，HDPE雙壁波紋管與其他管材相比較具有明顯的優(yōu)勢(shì)。 </p> <p> <br /> </p> <p> 工程造價(jià)低 </p> <p> 在同等負(fù)荷的條件下，HDPE雙壁波紋管只需要較薄的管壁就可以滿(mǎn)足要求。因此，與同材質(zhì)規(guī)格的實(shí)壁相管比，能節(jié)約一半左右的原材料，所以HDPE雙壁波紋管造價(jià)也較低。這是該管材的又一個(gè)很突出的特點(diǎn)，鎮(zhèn)海區(qū)耐低溫HDPE雙壁波紋管。 </p> <p> <br /> </p> <p> 施工方便 </p> <p> 由于HDPE雙壁波紋管重量輕，搬運(yùn)和連接都很方便，鎮(zhèn)海區(qū)耐低溫HDPE雙壁波紋管，鎮(zhèn)海區(qū)耐低溫HDPE雙壁波紋管，所以施工快捷、維護(hù)工作簡(jiǎn)單。在工期緊和施工 </p> <p> 條件差的情況況下，其優(yōu)勢(shì)更加明顯。 </p> <p> <br /> </p><div

d、擴(kuò)口前端的內(nèi)層有凹限引起這種現(xiàn)象的原因一般是內(nèi)層沖氣過(guò)早啟動(dòng)；水套與在型模塊的中線(xiàn)偏離（成型機(jī)與水套不對(duì)中）；內(nèi)層壁厚偏??；內(nèi)層真空過(guò)早停止。 </p> <p> <br /> </p> <p> e、擴(kuò)口末端內(nèi)層堆料，這種現(xiàn)象往往會(huì)導(dǎo)致擴(kuò)口往里面凹。其原因是擴(kuò)口末端內(nèi)層料過(guò)厚；成型機(jī)在此段的降速的量過(guò)大；之前幾段的內(nèi)層沖氣過(guò)大；內(nèi)層的料溫過(guò)高致料坯過(guò)軟；外層的料坯在此段過(guò)厚。 </p> <p> <br /> </p> <p> f、擴(kuò)口末端的內(nèi)層有凹限其原因一般是擴(kuò)口后的個(gè)波和第二個(gè)波內(nèi)的氣壓過(guò)?。粩U(kuò)口后的個(gè)波和第二個(gè)波所對(duì)應(yīng)的內(nèi)層壁厚過(guò)厚；內(nèi)層真空度較小或內(nèi)層真空啟動(dòng)過(guò)晚；原材料的韌性差等。 </p><div
