Galvanizing Qulqulka kulul, sidoo kale loo yaqaan galvanizing, waa hab lagu quusiyo qaybaha birta ee zinc dhalaalaysa si loo helo daahan bir ah. Galvanizing Electro waxaa caadi ahaan loo yaqaan "galvanizing qabow" ama "biyo galvanizing";Waxay isticmaashaa kiimikooyinka elektiroonigga ah, iyada oo la isticmaalayo zinc ingot sida anode.Atomyada zinc waxay lumiyaan elektaroonada waxayna noqdaan ions waxayna ku milmaan elektrolytka, halka walxaha birta ah ay u dhaqmaan sidii anode.Marka la joogo cathode, ions zinc waxay ka helaan elektaroonnada birta waxaana lagu dhimaa atamka zinc ee lagu shubo dusha sare ee birta si loo gaaro habraaca kaas oo daahanku uu sameeyo lebbis, cufan, iyo bir si fiican isku xidhan ama lakabka dhigaalka alloy. Maqaalkani wuxuu si qoto dheer kuugu sharaxayaa farqiga u dhexeeya labada.
1. Dhumucda dahaarka kala duwan
Daahanka kulul ee galvanized galvanized ee kulul guud ahaan wuxuu leeyahay lakabka zinc dhumucdiisuna, qiyaastii 40 μm ama ka badan, ama xataa ilaa 200 μm ama ka badan.Lakabka kulul ee galvanized-ka ah ayaa guud ahaan 10 ilaa 20 jeer ka badan lakabka zinc-ga ee korantada.Daahanka korantada ee zinc waa mid aad u dhuuban, oo ku saabsan 3-15μm, miisaanka dahaarkana waa 10-50g/m2 kaliya.
2. xaddi galvanizing kala duwan
Qadarka galvanizing ee gariiradaha birta galvanized ee kulul ma noqon karaan kuwo aad uyar.Guud ahaan, ugu yaraan waa 50 ~ 60g/m2 labada dhinac iyo ugu badnaan waa 600g/m2.Lakabka galvanized ee gariiradaha birta galvanized electro galvanized waxay noqon kartaa mid aad khafiif ah, oo leh ugu yaraan 15g/m2.Si kastaba ha noqotee, haddii daahan loo baahan yahay inuu noqdo mid dhumucdiisuna, xawaaraha khadka wax soo saarku wuxuu noqon doonaa mid aad u gaabis ah, taas oo aan ku haboonayn sifooyinka habka ee cutubyada casriga ah.Guud ahaan, ugu badnaan waa 100g/m2.Sababtan awgeed, wax soo saarka ee xaashida birta galvanized electro galvanized aad ayaa loo xaddiday.
3. Qaab dhismeedka dahaarka ayaa ka duwan
Waxa jira daaha ka samaysan wax yar oo jajaban oo u dhexeeya daahan zinc saafiga ah ee xaashida kulul ee galvanized galvanized iyo saxanka birta ah.Marka dahaadhka zinc ee saafiga ah uu dhalaaliyo, inta badan ubaxyada zinc ayaa la sameeyay, dahaarkana waa labis oo aan lahayn dalool.Atamyada zinc-ka ee ku jira lakabka korantada ee zinc-ka ayaa kaliya ku soo daadanaya oogada saxanka birta, waxayna si jidh ahaan ugu dheggan yihiin dusha sare ee fiilada birta.Waxaa jira daloolo badan, kuwaas oo si fudud u keeni kara daxalka godka sababtoo ah warbaahinta daxalka ah.Sidaa darteed, taarikada galvanized-kuleelka kulul ayaa ka adkeysi badan daxalka taargooyinka galvanized electro.
4. Hababka daaweynta kulaylka ee kala duwan
Biraha birta galvanized ee kulul ayaa guud ahaan laga sameeyay taarikada adag ee qabow waxaana si joogto ah loo tirtiraa waxaana lagu dhejiyaa galvanizing kulul khadka galvanizing.Xarigga birta ah ayaa la kululeeyaa wakhti gaaban ka dibna la qaboojiyo, markaa xoogga iyo balaastiga ayaa saameeya ilaa xad.Wax qabadkeeda shaabadeynta ayaa ka fiican isla saxan adag oo qabow oo ka duwan saxan birta duuban ee qabow ka dib markii la nadiifiyo oo la tirtiro khadka wax soo saarka ee xirfadlaha ah.Waraaqaha birta ah ee la rusheeyey ee kulul ayaa leh kharash-soo-saar hoose iyo kala duwanaansho codsi oo ballaadhan, waxayna noqdeen noocyada ugu muhiimsan ee suuqa xaashida galvanized.Walxaha birta ah ee galvanized Electro waxay isticmaalaan birta duuban ee qabow sida alaabta ceeriin, taas oo asal ahaan dammaanad qaadaya waxqabadka habaynta ee xaashida qabowga, laakiin habka adag ayaa sidoo kale kordhiya kharashka wax soo saarka.
5. Muuqaal kala duwan
Dusha sare ee lakabka galvanized dip kulul waa qallafsan oo dhalaalaya, iyo xaaladaha daran waxaa jira ubax zinc;lakabka galvanized electro waa siman oo cawl ( wasakhaysan ).
6. Baaxadaha codsiga iyo hababka kala duwan
Galvanizing-kululku wuxuu ku habboon yahay qaybo waaweyn iyo qalab;galvanization-ku-kulul waa in marka hore la guro tuubada birta.Si loo soo saaro oksaydhka birta ee dusha sare ee tuubada birta, ka dib marka la qaado, waxaa la dhex maraa ammonium chloride ama zinc chloride aqueous ama ammonium chloride iyo chlorine.Zinc isku qasan haanta dareeraha aqueous si loo nadiifiyo, ka dibna loo diro haanta saxarada kulul ee kulul.
Gariiradda birta galvanized ee kulul ayaa leh dabool wanaagsan, daahan cufan, iyo wax wasakh ah oo lagu daro.Waxay leedahay faa'iidooyinka daahan labbiska ah, adhesion xooggan iyo nolol adeeg oo dheer.Galvanizing-ku-kulul ayaa iska caabin wanaagsan u leh daxalka atmospheric ee birta saldhigga ah marka loo eego electro-galvanizing.
Waraaqaha birta ah ee galvanized ee lagu sameeyay koronto-ku-sameynta waxay leeyihiin waxqabad habaysan oo wanaagsan, laakiin dahaarka ayaa khafiif ah oo iska caabbinta daxalka uma fiicna sida xaashida birta galvanized ee kulul;Qadarka Zinc ee ku xidhan gariiradda birta galvanized ee elektro galvanized aad u yar, oo kaliya derbiga tuubada dibadda waa galvanized, halka galvanizing-kulul-kulan waa gudaha iyo dibadda labadaba.
