1太陽能熱水器的輸水管道用鋁塑管好還是ppr管好PPR管耐低溫差。PPR有冷脆性（脆點(diǎn)為-20℃），在冬季（5℃以下）施工時即需特別小心。鋁塑管無冷脆性（脆點(diǎn)為-70℃），在-20℃以下亦可輕松安裝。PPR管耐熱性低于鋁塑管。PPR的長期使用溫度70℃（50年，1MPa），較高使用溫度95℃；鋁塑管長期使用溫度95℃（50年，1MPa）,較高使用溫度110℃。PPR管線膨脹系數(shù)較大，約為·℃，意即受外部溫度（如冬夏季）或內(nèi)部水溫（冷、熱水）變化時，有較大的變形量，由于PPR管為剛性直管，本身不能消化變形量，故易造成管路系統(tǒng)彎曲變形甚至漏水，而鋁塑管因其與鋁復(fù)合成整體，其線膨脹系數(shù)同鋁相當(dāng)，約·℃，為PPR管的1/6，故受溫度變化時，變形量較小，且鋁塑管為柔性盤管，管道本身可以消化一定的變形量，不會造成管路系統(tǒng)的熱脹變形。PPR管耐老化性差，PPR分子鏈結(jié)構(gòu)-（-CH2—CH-）n-中含大量不穩(wěn)定2輸水管道內(nèi)部涂油漆防腐,一般選環(huán)氧樹脂漆,可是怎么實(shí)現(xiàn)呢怎么弄呢涂裝油漆怎么還要配方呢？環(huán)氧樹脂漆都是雙組分的，主劑和固化劑配在一起攪拌后，30分鐘熟化就可以使用了，難道你還要自己制作環(huán)氧樹脂底漆？這個配方很好弄，但是沒有設(shè)備你也制作不出來?。拷ㄗh你到商店里買吧。安順玻璃鋼輸水管標(biāo)準(zhǔn)管徑6、使用壽命長，因此總體造價(jià)低廉。</p><div
