style="text-indent:25px">銅是一種質(zhì)地堅硬的金屬，而腐蝕。能在種不同的環(huán)境中使用而不損壞。從國外的使用歷史來看，許多銅管道的使用時間已超了建筑物本身的使用壽命。因此銅水管是***安全可靠的水管。銅可以說是具有“綠色面孔的紅色金屬”。銅能抑制細菌生長，保持飲用水清潔衛(wèi)生。銅制餐飲具歷史悠久、無味。銅管及配件在高溫、高壓下仍能保持其形狀和強度，也不會有長期老化現(xiàn)象。銅管有一層密實堅硬的保護層，無論是油脂，碳水化合物，細菌和，有害液體，空氣或紫外線均不能穿過它也不能侵蝕它污染水質(zhì)。寄生物也不能棲息于銅表面。但銅管價位高是它的比較大缺點，是目前比較高級的水管。資陽管件閥門推薦</p><p
