　　鋅合(he)金犧牲陽(yang)極執行(xing)標準：GB/T4950-2002又稱(cheng)鋅合(he)金陽(yang)極、鋅合(he)金犧牲陽(yang)極

　　主(zhu)要(yao)用途：鋅犧(xi)牲陽極適用于海(hai)(hai)水(shui)、淡海(hai)(hai)水(shui)介質中的(de)(de)(de)船舶、機械設(she)(she)備、海(hai)(hai)洋工程和海(hai)(hai)港設(she)(she)施以(yi)及低電阻(zu)率土壤(rang)中的(de)(de)(de)管道、電纜等設(she)(she)施金屬防(fang)腐蝕的(de)(de)(de)陰極保護。

　　鋅陽(yang)(yang)極(ji)(ji)規格按(an)照用(yong)(yong)(yong)途分為：1.船(chuan)(chuan)體(ti)用(yong)(yong)(yong)焊接(jie)(jie)式犧(xi)牲(sheng)(sheng)(sheng)陽(yang)(yang)極(ji)(ji)(單鐵腳)2.船(chuan)(chuan)體(ti)用(yong)(yong)(yong)焊接(jie)(jie)式犧(xi)牲(sheng)(sheng)(sheng)陽(yang)(yang)極(ji)(ji)(雙鐵腳)3.船(chuan)(chuan)體(ti)用(yong)(yong)(yong)螺栓連接(jie)(jie)式犧(xi)牲(sheng)(sheng)(sheng)陽(yang)(yang)極(ji)(ji)4.壓(ya)載水(shui)艙(cang)常(chang)用(yong)(yong)(yong)犧(xi)牲(sheng)(sheng)(sheng)陽(yang)(yang)極(ji)(ji)5.港口和海洋工程設施用(yong)(yong)(yong)犧(xi)牲(sheng)(sheng)(sheng)陽(yang)(yang)極(ji)(ji)6.海水(shui)冷(leng)(leng)卻水(shui)系統用(yong)(yong)(yong)長(chang)條(tiao)形(xing)犧(xi)牲(sheng)(sheng)(sheng)陽(yang)(yang)極(ji)(ji)7.海水(shui)冷(leng)(leng)卻水(shui)系統用(yong)(yong)(yong)圓盤狀(zhuang)犧(xi)牲(sheng)(sheng)(sheng)陽(yang)(yang)極(ji)(ji)8.埋地(di)管(guan)線用(yong)(yong)(yong)犧(xi)牲(sheng)(sheng)(sheng)陽(yang)(yang)極(ji)(ji)

　　簡介:

　　鋅犧牲陽(yang)(yang)極(ji)多(duo)用(yong)于(yu)土(tu)壤(rang)電(dian)阻(zu)率(lv)小(xiao)于(yu)20歐姆?米的土(tu)壤(rang)環(huan)(huan)境(jing)(jing)中或(huo)海水環(huan)(huan)境(jing)(jing)。電(dian)極(ji)電(dian)位為-1.10VCSE，驅動(dong)電(dian)壓0.25V。溫度高于(yu)49℃時(shi)，發生晶(jing)間腐蝕，高于(yu)54℃時(shi)鋅陽(yang)(yang)極(ji)的電(dian)極(ji)電(dian)位變(bian)正，它與(yu)鋼鐵(tie)的極(ji)性發生逆轉，變(bian)成陰(yin)極(ji)受(shou)到保護(hu)，而鋼鐵(tie)變(bian)成陽(yang)(yang)極(ji)受(shou)到腐蝕。所以，鋅陽(yang)(yang)極(ji)一(yi)般(ban)用(yong)于(yu)溫度低于(yu)49℃的環(huan)(huan)境(jing)(jing)。鋅陽(yang)(yang)極(ji)必(bi)須使用(yong)回填(tian)料.

　　鋅接(jie)地(di)電(dian)(dian)池是由兩支(zhi)或者4支(zhi)1.5m長的(de)鋅棒，用絕緣墊塊隔開(kai)，并用膠帶綁在一起，共同填(tian)裝在導電(dian)(dian)性(xing)填(tian)包(bao)料中，應用時，將與(yu)鋼芯(xin)相連(lian)的(de)電(dian)(dian)纜引線(xian)分別接(jie)在絕緣件的(de)兩側，為絕緣件提供(gong)一個(ge)低(di)電(dian)(dian)壓旁接(jie)回(hui)路，一般在水飽和情況下其電(dian)(dian)阻為0.2-0.6歐，如果2支(zhi)型的(de)電(dian)(dian)阻滿足不(bu)了要(yao)求(qiu)時可用4支(zhi)型電(dian)(dian)池。

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

　　鋅(xin)-鋁-鎘合金犧(xi)牲(sheng)陽極適(shi)用于海(hai)水、淡(dan)海(hai)水介(jie)質中(zhong)的(de)船舶、機械設備、海(hai)洋工程和海(hai)港設施以及低電阻率土壤(rang)中(zhong)的(de)管道、電纜等設施金屬防(fang)腐的(de)陰極保護
