1、冷熱(re)水(shui)管(guan)(guan)主要是以PPR水(shui)管(guan)(guan)為主,既(ji)可作(zuo)冷水(shui)管(guan)(guan)也可作(zuo)熱(re)水(shui)管(guan)(guan),無毒(du)耐(nai)壓(ya)耐(nai)腐(fu)蝕。冷水(shui)管(guan)(guan)一般外面會(hui)(hui)有藍色標記的直(zhi)線,熱(re)水(shui)管(guan)(guan)則(ze)是外面有紅色線標記的管(guan)(guan)材,材料(liao)及價格會(hui)(hui)有些(xie)微區分,不(bu)要弄錯了。
2、飲用水管(guan)(guan)(guan)需不(bu)結垢不(bu)生(sheng)銹、具有環保安全抗(kang)菌(jun)性,因此一般以PE管(guan)(guan)(guan)、PPR管(guan)(guan)(guan)為(wei)主。PE給水管(guan)(guan)(guan)一般只做冷水管(guan)(guan)(guan),而PPR管(guan)(guan)(guan)可做冷熱水管(guan)(guan)(guan)。在裝修中可兩種(zhong)管(guan)(guan)(guan)材(cai)搭配使用。
3、家用(yong)排水(shui)管(guan)(guan)(guan)道、下水(shui)管(guan)(guan)(guan)對管(guan)(guan)(guan)道材質的(de)要求(qiu)不是很(hen)高(gao)(gao),通常(chang)是以UPVC排水(shui)管(guan)(guan)(guan)為(wei)主,其耐(nai)化(hua)學腐蝕,抗沖強度高(gao)(gao),耐(nai)老化(hua),使用(yong)壽命(ming)長,使用(yong)年(nian)限不低于(yu)50年(nian),是建筑給排水(shui)的(de)理想材料。
4、電路是(shi)家(jia)裝(zhuang)(zhuang)裝(zhuang)(zhuang)修(xiu)中的重(zhong)要環節,暗(an)線(xian)在墻(qiang)(qiang)內,明線(xian)則在墻(qiang)(qiang)上。由于家(jia)裝(zhuang)(zhuang)電路眾多,可(ke)用電線(xian)管,可(ke)以(yi)保(bao)護線(xian)纜,方便今后(hou)的維(wei)護,一般選用PVC線(xian)管,絕緣性能好、阻燃防火、耐(nai)熱抗壓。
5、地(di)暖(nuan)(nuan)(nuan)管分(fen)水(shui)地(di)暖(nuan)(nuan)(nuan)和電(dian)(dian)(dian)地(di)暖(nuan)(nuan)(nuan),水(shui)地(di)暖(nuan)(nuan)(nuan),是(shi)以溫(wen)度(du)不(bu)高于60℃的(de)熱(re)水(shui)埋于地(di)下填充層中(zhong)的(de)加(jia)熱(re)管內循(xun)環流動(dong),惻然加(jia)熱(re)整個地(di)板;而電(dian)(dian)(dian)地(di)暖(nuan)(nuan)(nuan)是(shi)將外(wai)表面允許工作溫(wen)度(du)上限(xian)為65℃的(de)發熱(re)電(dian)(dian)(dian)纜埋設在地(di)板中(zhong),以發熱(re)電(dian)(dian)(dian)纜為熱(re)源加(jia)熱(re)地(di)板。通(tong)常比較常見的(de)水(shui)地(di)暖(nuan)(nuan)(nuan)管以PERT管材為主,而電(dian)(dian)(dian)地(di)暖(nuan)(nuan)(nuan)則采用發熱(re)電(dian)(dian)(dian)纜。
