帶狀鋅合金犧牲(sheng)陽極主(zhu)要用于高電阻率環境，套管(guan)(guan)內管(guan)(guan)道(dao)的保護，管(guan)(guan)道(dao)臨時陰極保護、儲罐及管(guan)(guan)網(wang)的保護、防強電干擾的接(jie)地柵。
原理：
腐(fu)蝕(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)體(ti)系正在作用(yong)時(shi)，接入另一電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)絲，該(gai)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)的(de)電(dian)(dian)(dian)(dian)(dian)位較負，這(zhe)個(ge)(ge)時(shi)候原(yuan)腐(fu)蝕(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)就(jiu)與(yu)這(zhe)個(ge)(ge)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)就(jiu)組成了一個(ge)(ge)新(xin)的(de)宏觀(guan)電(dian)(dian)(dian)(dian)(dian)。從(cong)電(dian)(dian)(dian)(dian)(dian)化學原(yuan)理來說(shuo)，負的(de)電(dian)(dian)(dian)(dian)(dian)極(ji)(ji)就(jiu)是(shi)這(zhe)個(ge)(ge)新(xin)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)陽(yang)極(ji)(ji)，所謂(wei)的(de)陰(yin)極(ji)(ji)便是(shi)原(yuan)腐(fu)蝕(shi)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。從(cong)電(dian)(dian)(dian)(dian)(dian)解(jie)質(zhi)向被(bei)保(bao)(bao)(bao)護(hu)體(ti)從(cong)陽(yang)極(ji)(ji)體(ti)提(ti)供一個(ge)(ge)陰(yin)極(ji)(ji)電(dian)(dian)(dian)(dian)(dian)流(liu)，這(zhe)時(shi)被(bei)保(bao)(bao)(bao)護(hu)體(ti)就(jiu)會(hui)進行陰(yin)極(ji)(ji)保(bao)(bao)(bao)護(hu)，就(jiu)會(hui)完成陰(yin)極(ji)(ji)保(bao)(bao)(bao)護(hu)。伴隨著(zhu)陽(yang)極(ji)(ji)材料不斷消(xiao)耗(hao)不斷流(liu)出電(dian)(dian)(dian)(dian)(dian)流(liu)，這(zhe)樣就(jiu)有了犧牲陽(yang)極(ji)(ji)。
安裝：
鋅帶(dai)(dai)陽(yang)極首先(xian)第一步是(shi)(shi)檢(jian)(jian)查，在施工(gong)現場可(ke)以(yi)找一個比較(jiao)空曠的(de)(de)地(di)方把(ba)鋅帶(dai)(dai)陽(yang)極卷慢(man)慢(man)散開，在平地(di)上(shang)把(ba)陽(yang)極帶(dai)(dai)捋直。如(ru)果(guo)周圍溫度非常低的(de)(de)情況下(xia)，應該(gai)慢(man)慢(man)散開陽(yang)極帶(dai)(dai)，盡可(ke)能(neng)的(de)(de)減少彎(wan)曲，因為溫度低的(de)(de)時候鋅陽(yang)極帶(dai)(dai)比較(jiao)容易折(zhe)斷(duan)。把(ba)陽(yang)極帶(dai)(dai)捋直后(hou)，根(gen)據設計(ji)規定將陽(yang)極帶(dai)(dai)截(jie)成合適的(de)(de)長度。然(ran)(ran)后(hou)開始安裝，首先(xian)檢(jian)(jian)查陽(yang)極帶(dai)(dai)表(biao)(biao)面是(shi)(shi)不是(shi)(shi)有油污或者其他雜質(zhi)，用(yong)(yong)(yong)抹布或者砂紙輕(qing)輕(qing)將陽(yang)極上(shang)的(de)(de)雜質(zhi)擦拭干(gan)凈。接(jie)(jie)下(xia)來(lai)的(de)(de)工(gong)作(zuo)是(shi)(shi)要(yao)(yao)剝出陽(yang)極兩端的(de)(de)鐵(tie)(tie)芯(xin)(xin)，為了保證施工(gong)安全，應該(gai)使用(yong)(yong)(yong)鋼(gang)鋸和手鉗之類的(de)(de)工(gong)具，大概需要(yao)(yao)20毫(hao)米左右的(de)(de)長度。將鐵(tie)(tie)芯(xin)(xin)剝出來(lai)以(yi)后(hou)用(yong)(yong)(yong)鐵(tie)(tie)砂紙用(yong)(yong)(yong)鐵(tie)(tie)芯(xin)(xin)打光，最后(hou)套上(shang)收(shou)宿管(guan)(guan)(guan)。然(ran)(ran)后(hou)將電纜(lan)(lan)的(de)(de)銅芯(xin)(xin)剝出20毫(hao)米，用(yong)(yong)(yong)銅管(guan)(guan)(guan)把(ba)陽(yang)極的(de)(de)鐵(tie)(tie)芯(xin)(xin)和電纜(lan)(lan)的(de)(de)銅芯(xin)(xin)用(yong)(yong)(yong)液壓鉛(qian)壓實(shi)。用(yong)(yong)(yong)萬(wan)用(yong)(yong)(yong)表(biao)(biao)檢(jian)(jian)查連接(jie)(jie)處(chu)(chu)的(de)(de)導通性。在接(jie)(jie)頭(tou)處(chu)(chu)用(yong)(yong)(yong)膠帶(dai)(dai)纏(chan)繞密封，并用(yong)(yong)(yong)收(shou)縮帶(dai)(dai)收(shou)緊。鋅帶(dai)(dai)陽(yang)極的(de)(de)鋪設方法(fa)(fa)可(ke)以(yi)鋪在管(guan)(guan)(guan)道(dao)的(de)(de)旁邊，也(ye)可(ke)以(yi)纏(chan)繞在管(guan)(guan)(guan)道(dao)上(shang)。方法(fa)(fa)必須要(yao)(yao)按照設計(ji)要(yao)(yao)求來(lai)操作(zuo)，并按照要(yao)(yao)求連接(jie)(jie)電纜(lan)(lan)線。
