Wararka

Galvanizing Qulqulka Kulul, oo sidoo kale loo yaqaan galvanizing maquufin kulul iyo galvanizing kulul, waa hab wax ku ool ah oo ka hortagga daxalka birta, inta badan loo isticmaalo dhismayaasha birta iyo tas-hiilaadka warshadaha kala duwan.Waa in lagu dhex miliyo qaybaha birta burburay ee zinc la dhalaaliyay qiyaastii 500 ℃ si loogu hoggaansamo lakab zinc ah oogada qaybaha birta, si loo gaaro ujeeddada ka hortagga daxalka.Qulqulka kuleylka kuleylka leh ee qulqulaya qulqulka qulqulka: badeecada dhammaatay - biyo-dhaqashada - ku darista xalinta cawska caawinta - qalajinta - dhejinta - qaboojinta - daaweynta - nadiifinta - polishing - dhamaystirka galvanizing dip kulul horumarinta birta xariijimaha qabow duuban, warshadaha galvanizing quusin kulul ayaa horumariyay on baaxad weyn.
Galvanizing Qulqulka Kulul, oo sidoo kale loo yaqaan galvanizing-kuleelka kulul, waa hab lagu helo dahaarka birta ee qaybaha birta iyadoo lagu dhex gelinayo zinc dhalaalaysa.Iyada oo horumarinta degdega ah ee gudbinta korantada sare, gaadiidka, iyo isgaadhsiinta, shuruudaha ilaalinta qaybaha birta ayaa sii kordheysa, iyo baahida loo qabo galvanizing kulul oo kulul ayaa sidoo kale sii kordhaya.

Waxqabadka ilaalinta
Guud ahaan, dhumucda lakabka galvanized waa 5 ~ 15 μm.Lakabka galvanized-kuleelka guud ahaan waa 35 μ Korka m, xitaa ilaa 200 μmWaxaa la og yahay in hababka zinc u caabbinta daxalka atmospheric ay ka mid yihiin ilaalinta farsamada iyo ilaalinta korantada.Marka la eego xaaladaha daxalka atmospheric, dusha lakabka zinc wuxuu leeyahay ZnO, Zn (OH) 2, iyo filimada ilaalinta aasaasiga ah ee zinc carbonate, kuwaas oo ilaa xad hoos u dhigaya daxalka zinc.Haddii filimkan difaaca (sidoo kale loo yaqaan miridhku cad) uu dhaawacmo, wuxuu samayn doonaa lakab filim oo cusub.Marka lakabka zinc uu si ba'an u waxyeeloobo oo uu khatar galiyo substrate-ka birta, zinc wuxuu bixiyaa ilaalinta korantada ee substrate-ka.Awoodda caadiga ah ee zinc waa -0.76V, iyo awoodda caadiga ah ee birta waa -0.44V.Marka zinc iyo birta ay sameeyaan batari yar, zinc waxaa lagu milmaa sida anode, iyo birta waxaa loo ilaaliyaa sida cathode.Sida iska cad, iska caabinta daxalka atmospheric ee galvanizing-kuleelka kulul ee birta salka birta ah ayaa ka fiican tan korantada.
Habka samaynta daahan Zinc
Habka formation of lakabka galvanized maquufin kulul waa habka of samaynta daawaha zinc bir u dhexeeya substrate birta iyo lakabka zinc saafi ah ka baxsan Z. Lakabka daawaha zinc birta waxaa la sameeyey on dusha workpiece ah inta lagu guda jiro dahaadhaynta kulul, kaas oo u ogolaanaya isku darka wanaagsan u dhexeeya birta iyo lakabka zinc saafi ah.Geedi socodka waxaa si fudud loo sifayn karaa sida soo socota: Marka workpiece birta la geliyo dareeraha zinc la dhalaaliyay, zinc iyo zinc marka hore la sameeyay on interface α Iron (jirka core) dhalaalid adag.Kani waa kareem ku samaysmay kala diri atamka zinc ee xaalada adag ee birta saldhiga ah.Labada atom ee birta ah waa isku dhafan yihiin, soo jiidashada u dhaxaysa atamka waa mid yar.Sidaa darteed, marka Zinc gaadho saturation ee dhalaalka adag, labada atamka elemental ee zinc iyo birta u kala firdhiso midba midka kale, iyo atomamka zinc ku firdhiyey (ama dhex galiyay) matrixka birta u haajiraan ee shabagga matrix, si tartiib tartiib ah samaynta alloy leh birta ah, halka birta iyo zinc ku firdhiyey galay shuban zinc dareere ah oo ka samaysan sinjiga sare ee Fee3 Dheriga izing, samaynta slag zinc.Marka qaybta shaqada laga saaro xalinta zinc-ka, lakabka zinc saafiga ah ayaa laga sameeyay dusha sare, kaas oo ah crystals hexagonal.Waxa ku jira birta aan ka badnayn 0.003%.
Kala duwanaanshaha farsamada
Iska caabbinta daxalka ee galvanizing kulul ayaa aad uga sarreeya kan galvanizing qabow (sidoo kale loo yaqaan galvanization).Galvanizing kulul kuma daxaloobayo dhawr sano gudahood, halka galvanizing qabow uu miridhku doono saddex bilood gudahood.
Habka electrogalvanizing waxaa loo isticmaalaa si looga ilaaliyo biraha daxalka."Waxaa jiri doona lakab ilaalin bir ah oo wanaagsan oo ku yaala cidhifyada iyo dusha sare ee alaabta, taas oo ku dareysa qayb qurux badan oo wax ku ool ah.Maalmahan, shirkadaha waaweyni waxay leeyihiin shuruudo sii kordheysa oo loogu talagalay qaybaha alaabada iyo tignoolajiyada, sidaa darteed waxaa lagama maarmaan ah in dib loo habeeyo tignoolajiyada heerkan.
