Waa maxay dabeecadda lidka ku ah xaashida galvanized?

Muhiimadda dhabta ah ee galvanizing quusidda kulul ee xaashi galvanized waxay ku xiran tahay in caabbinta daxalka ee birta duuban ee kulul ay si weyn u wanaajiso ka dib markii lakabka sare ee galvanizing dip kulul la daboolay, kaas oo badbaadin kara alaabta ceeriin iyo kheyraadka oo si buuxda u siinaya faa'iidooyinka dhaqaale ee wanaagsan iyo faa'iidooyinka deegaanka dabiiciga ah.  

Furaha waxtarka dayactirka lakabka galvanizing kulul ee xaashida galvanized ee birta duuban ee kulul waa sida soo socota:  

(1) marka dusha sare ee saxanka birta qaro weyn yahay, kaliya daxalka zinc, sababtoo ah maaddada daxalka zinc waxay leedahay saameyn dayactir ah oo wanaagsan, sidaas darteed heerka daxalka waa mid aad u gaabis ah, nolosha adeeggu waxay noqon doontaa 15-30 jeer saxan birta galvanized.  

(2) Xaaladda ugu caansan waa xaashi galvanized ee wax soo saarka iyo farsamaynta, rakibidda, codsiga, xagashada dusha sare, ama sabab kasta oo kale oo lakabka hoostiisa ah ee qaybta waxyeello u geystay, birta duuban ee kulul ee ka soo baxa boogta deegaanka dabiiciga ah, haddii ay tahay kiimikooyinka Qalabka aan biraha ahayn, baloogyada bannaanka ah waa la tirtiri doonaa, laakiin sifooyinka dayactirka ee xaashida qaboojiyaha qabow ee gaarka ah, samee heerka etching waa mid gaabis ah, habkan Zinc ee dahaarka iyo birta ku jirta birta birta duuban ee kulul waxay ka kooban tahay galvanic. unugga deegaanka qoyan iyo qabow, sababtoo ah awoodda electrode caadiga ah ee zinc waa kaliya -1.05V, ka yar -0.036V ee birta, sidaas zinc sida oxidation anodic by oxidation hawada, iyo birta sida saxan taban si loo helo dayactirka. Sababtoo ah alaabooyinka ka dib zinc waa cufnaanta aad u sarreeya, waqtiga falcelinta waa mid gaabis ah, si kale haddii loo dhigo, caabbinta guud ee daxalka ayaa si weyn loo hagaajiyay. Habka ka-hortagga noocan ah waxaa loo yaqaan caabbinta daxalka.
