止水紫銅板的性能和用途

紫銅止水片，其主要特點有：抗腐蝕能力強；強度高，能承受較大變形；外觀輪廓清晰，無裂紋、壓折、凹坑。適用于各類水工建筑的基礎止水、壩身止水、壩頂止水、廊道止水，以及壩體內孔洞止水、廠房止水、溢流面下橫縫止水等，是防止疏漏的產品[1] 要了解紫銅止水帶，首先來了解下紫銅：紫銅就是銅單質，因其顏色為紫紅色而得名。各種性質見銅。紫銅就是工業純銅，其熔點為1083℃，無同素異構轉變，相對密度為8.9，為鎂的五倍。比(bi)普通鋼還重約15%。其(qi)具有(you)(you)玫瑰紅(hong)色(se)，表面形成氧(yang)化膜后(hou)呈紫(zi)(zi)色(se)，故一般稱為紫(zi)(zi)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)。它(ta)是(shi)含有(you)(you)一定氧(yang)的銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)，因而又稱含氧(yang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)。紫(zi)(zi)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong) 因呈紫(zi)(zi)紅(hong)色(se)而得名。它(ta)不一定是(shi)純(chun)(chun)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)，有(you)(you)時還加入少量脫氧(yang)元素或(huo)其(qi)他元素,以改善材質和(he)(he)(he)性能,因此也歸入銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)合金。中(zhong)國紫(zi)(zi)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)加工材按成分(fen)可分(fen)為：普通紫(zi)(zi)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)(T1、T2、T3、T4)、無氧(yang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)（TU1、TU2和(he)(he)(he)高純(chun)(chun)、真空無氧(yang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)）、脫氧(yang)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)（TUP、TUMn）、添加少量合金元素的特(te)種銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)（砷銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)、碲銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)、銀銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)）四類。紫(zi)(zi)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)的電(dian)(dian)導率和(he)(he)(he)熱導率僅次于銀，廣泛用于制作導電(dian)(dian)、導熱器材。紫(zi)(zi)銅(tong)(tong)(tong)(tong)(tong)(tong)(tong)在大(da)氣(qi)、海水和(he)(he)(he)某些非(fei)氧(yang)化性酸(suan)(suan)（鹽酸(suan)(suan)、稀硫酸(suan)(suan)）、堿、鹽溶液及(ji)多種有(you)(you)機酸(suan)(suan)（醋酸(suan)(suan)、檸檬酸(suan)(suan)）中(zhong)，有(you)(you)良好(hao)的耐(nai)蝕性，用于化學工業。
