但這些做法只是使維修成為可能，處理起來仍顯麻煩。在同層排水的推廣應(yīng)用中，人們不能接受的還是管道漏水的問題，不管在降板沉槽內(nèi)、墊層中，還是假墻中，一旦管道漏水，維修處理麻煩，且易造成衛(wèi)生間污染、細(xì)菌滋生等問題。因此，要充分發(fā)揮同層排水的優(yōu)勢，在現(xiàn)代建筑中營造舒適、衛(wèi)生、節(jié)能的環(huán)境，同層排水系統(tǒng)管材的選用是主要問題。HDPE排水管在同層排水中的應(yīng)用2．1同層排水在我國住宅建筑排水中的應(yīng)用現(xiàn)狀國內(nèi)交付的商品房多為毛坯房，住戶在衛(wèi)生問的裝修施工中，由于造價(jià)及衛(wèi)生潔具選擇習(xí)慣等各種因素，使得同層排水不具備優(yōu)勢。但在全裝修及精裝修的住宅、公寓、別墅及賓館中應(yīng)用非常大面積，也有利于開發(fā)商提升建筑品質(zhì)和品牌競爭力。四川康泰塑膠HDPE給水管總代理在給排水管道系統(tǒng)中，塑料管材逐漸取代了鑄鐵管和鍍鋅鋼管等傳統(tǒng)管材成為了主流使用管材。</p><div

國際上把聚乙烯管的材料分為PE32、PE40、PE63、PE80、PE100五個(gè)等級(jí)，而用于燃?xì)夤芎徒o水管的材料主要是PE80和PE100。我國對(duì)聚乙烯管材**料沒有分級(jí)，這使得國內(nèi)聚乙烯燃?xì)夤芎徒o水管生產(chǎn)廠家選擇原材料比較困難，也給聚乙烯管材的使用帶來了不小的弊端。因此國家標(biāo)準(zhǔn)局在GB/T13663-2000新標(biāo)準(zhǔn)中作了大量的修訂，規(guī)定了給水管的不同級(jí)別PE80和PE100對(duì)應(yīng)不同的壓力強(qiáng)度，并且去掉舊標(biāo)準(zhǔn)中的拉伸強(qiáng)度性能，而增加了斷裂伸長率（大于350%），即強(qiáng)調(diào)基本韌性。 </p><p> ⑻水流阻力小：HDPE管道具有光滑的內(nèi)表面，其曼寧系數(shù)為。光滑的表現(xiàn)和非粘附特性保證HDPE管道具有較傳統(tǒng)管材更高的輸送能力，同時(shí)也降低了管路的壓力損失和輸水能耗。⑼搬運(yùn)方便：HDPE管道比混凝土管道、鍍鋅管和鋼管更輕，它容易搬運(yùn)和安裝，更低的人力和設(shè)備需求，意味著工程的安裝費(fèi)用的很大降低。⑽多種全新的施工方式：HDPE管道具有多種施工技術(shù)，除了可以采用傳統(tǒng)的開挖方式進(jìn)行施工外，還可以采用多種全新的非開挖技術(shù)如頂管、定向鉆孔、襯管、裂管等方式進(jìn)行施工，這對(duì)于一些不允許開挖的場所，是**的選擇，因此HDPE管道應(yīng)用領(lǐng)域更為大面積。因此， PE管的連接方式與 U－PVC管不同，通常采用電熱熔連接及熱熔對(duì)接兩種方式.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="四川塑膠HDPE給水管,HDPE給水管"
