　　鋅(xin)合金犧牲(sheng)陽極執(zhi)行標準：GB/T4950-2002又稱鋅(xin)合金陽極、鋅(xin)合金犧牲(sheng)陽極

　　主要用(yong)途：鋅犧牲(sheng)陽極(ji)適用(yong)于海(hai)水(shui)、淡海(hai)水(shui)介質(zhi)中(zhong)的(de)(de)船舶(bo)、機械(xie)設備、海(hai)洋工程和海(hai)港(gang)設施以(yi)及低電阻(zu)率土壤中(zhong)的(de)(de)管道、電纜等設施金(jin)屬防腐(fu)蝕的(de)(de)陰極(ji)保護。

　　鋅(xin)陽(yang)(yang)(yang)極(ji)規格按照(zhao)用(yong)(yong)(yong)途分(fen)為(wei)：1.船(chuan)體(ti)用(yong)(yong)(yong)焊接(jie)式(shi)犧牲(sheng)(sheng)陽(yang)(yang)(yang)極(ji)(單鐵(tie)腳(jiao))2.船(chuan)體(ti)用(yong)(yong)(yong)焊接(jie)式(shi)犧牲(sheng)(sheng)陽(yang)(yang)(yang)極(ji)(雙鐵(tie)腳(jiao))3.船(chuan)體(ti)用(yong)(yong)(yong)螺栓連接(jie)式(shi)犧牲(sheng)(sheng)陽(yang)(yang)(yang)極(ji)4.壓載水(shui)(shui)艙常用(yong)(yong)(yong)犧牲(sheng)(sheng)陽(yang)(yang)(yang)極(ji)5.港口和(he)海洋(yang)工程設施(shi)用(yong)(yong)(yong)犧牲(sheng)(sheng)陽(yang)(yang)(yang)極(ji)6.海水(shui)(shui)冷卻(que)水(shui)(shui)系(xi)統(tong)用(yong)(yong)(yong)長條(tiao)形犧牲(sheng)(sheng)陽(yang)(yang)(yang)極(ji)7.海水(shui)(shui)冷卻(que)水(shui)(shui)系(xi)統(tong)用(yong)(yong)(yong)圓盤狀犧牲(sheng)(sheng)陽(yang)(yang)(yang)極(ji)8.埋地(di)管線用(yong)(yong)(yong)犧牲(sheng)(sheng)陽(yang)(yang)(yang)極(ji)

　　簡介:

　　鋅(xin)犧牲陽(yang)極(ji)多用(yong)(yong)于(yu)土(tu)壤電(dian)(dian)阻率小(xiao)于(yu)20歐姆?米的土(tu)壤環境(jing)中或海水環境(jing)。電(dian)(dian)極(ji)電(dian)(dian)位(wei)為-1.10VCSE，驅動電(dian)(dian)壓0.25V。溫(wen)度(du)高于(yu)49℃時，發生晶間腐蝕，高于(yu)54℃時鋅(xin)陽(yang)極(ji)的電(dian)(dian)極(ji)電(dian)(dian)位(wei)變(bian)(bian)正(zheng)，它與鋼(gang)鐵的極(ji)性發生逆轉，變(bian)(bian)成(cheng)陰極(ji)受到(dao)保(bao)護，而(er)鋼(gang)鐵變(bian)(bian)成(cheng)陽(yang)極(ji)受到(dao)腐蝕。所以，鋅(xin)陽(yang)極(ji)一般用(yong)(yong)于(yu)溫(wen)度(du)低(di)于(yu)49℃的環境(jing)。鋅(xin)陽(yang)極(ji)必須使(shi)用(yong)(yong)回填(tian)料.

　　鋅接(jie)地電(dian)池是由兩(liang)(liang)支或者4支1.5m長的(de)鋅棒，用(yong)絕緣墊塊隔開，并用(yong)膠(jiao)帶綁在(zai)一起，共同填(tian)裝在(zai)導電(dian)性填(tian)包(bao)料(liao)中，應用(yong)時，將與鋼(gang)芯相連的(de)電(dian)纜引線分別接(jie)在(zai)絕緣件的(de)兩(liang)(liang)側，為絕緣件提供一個低電(dian)壓旁接(jie)回路，一般在(zai)水飽和情(qing)況(kuang)下其電(dian)阻(zu)為0.2-0.6歐，如果2支型(xing)的(de)電(dian)阻(zu)滿足不了要求時可用(yong)4支型(xing)電(dian)池。

　　鋅接地電池的材料和鋅陽極的成分是一樣的，所用(yong)填料的配方為：75%石膏粉，20%膨潤土，5%硫酸鈉。連接導線截(jie)面為銅芯電纜(lan)，國內多(duo)選用(yong)VV-1KV/1*16m㎡銅芯電纜(lan)。
