Gariiradaha Birta Dahaarka leh Midabka Aluzinc

Afaa'iido:

1.)adkeysiga Anticorrosion

Saxanka dahaarka leh ee midabku wuxuu leeyahay saamaynta muraayadda muraayadda. Marka lagu daro rullaluistemadka cadaadiska ee habka wax soo saarka ee saxan midabka, filimka difaaca ayaa aad ugu dhow ku lifaaqan dusha saxanka, taas oo ma aha oo kaliya ma saameeyaa foorarsiga iyo hababka kale ee processing, laakiin sidoo kale ka ilaalin kartaa dusha saxan ka dhaawac in habka of processing iyo shirka. Ku dhajinta dusha sare waa ka sii xoog badan tahay, adkeysiguna waa ka sii fiican yahay, mana jiri doonto dufan, dildilaac iyo dildilaac ka dib isticmaalka muddada dheer Cilladaha sida spalling iyo budada kale ee budada ah ee lagu buufiyo waa sahlan tahay inay muuqdaan, waxaana si adag loo xakameyn karaa iyadoo loo eegayo shuruudaha macaamiisha.

2.)Heerka fulinta

Shirkaddu waxay ku gudubtay IS09001, gbat24001, gba28001 shahaado tayo leh, la aasaasay oo la hagaajiyay nidaamka hubinta tayada. Marka la eego nidaam dhammaystiran oo ah nidaamka hubinta tayada, waxaa jira habab dhammaystiran laga bilaabo nidaamka illaa wax-soo-saarka iyo gaarsiinta, iyo heerarkan soo socda si adag ayaa loo fuliyaa.

• GB / T 12754 saxan bir ah oo midab leh iyo xariijin
• JIS g3312 "hore dahaarka kulul ku duugan xaashi bir galvanized iyo strip"
• TS EN 10169-1 alaabada xaashida birta ah ee joogtada ah ee dabiiciga ah ee dahaarka leh (ciilada dahaarka leh) - Qeybta 1: Macluumaadka guud (Qeexitaannada, agabka, dulqaadka, hababka tijaabada)
• TS EN 10169-2 "Daahan dabiiciga ah oo joogto ah (daahan duuban) alaabada saxanka birta ah" Qeybta 2: Dhisidda alaabada dibadda
• ASTM A755 "Taariko bir ah oo horay loo dahaadhay oo loogu talagalay isticmaalka bannaanka ee dhismayaasha ku salaysan taarikada birta kulul ee kulul oo lagu soo saaro habka daahan duuban"

3.)Substrate

Substrate-ka midabka dahaarka leh inta badan waxaa ka mid ah xaashida duuban ee qabow, xaashi galvanized ah iyo xaashida aluminium ee zinc. Dusha sare ee xaashida midabada leh ee substrate-ka qabow waa mid siman oo leh waxqabad habaysan oo wanaagsan, kaas oo ku habboon dhismayaasha gudaha ama qalabka guriga. Marka laga soo tago caabbinta wanaagsan ee dahaadhka dusha sare, dahaarka zinc wuxuu sidoo kale leeyahay saameyn wanaagsan oo ka hortagga daxalka ee substrate, iyo ilaalinta cirifka goynta ayaa ka fiican noocyada kale ee substrates. Dusha sare ee dusha sare ee looxa midabka midabku waa mid siman oo qurux badan; Miisaanka lakabka zinc waxaa lagu go'aamin karaa hadba baahidaada.

Socodka habka

Csaxan bir dahaarka ah sida caadiga ah birta galvanized, GL ka dib daawaynta dusha sare ee ay dahaarka leh dhumucdiisuna waxay gaar ah ee daahan koolo ama lakabka of film organic, daawaynta ka dib, noqon saxan midabka, oo leh caabbinta daxalka aad u fiican, qaabaynta, qurxinta ee dhismaha, qalabka guriga, warshadaha iftiinka, gaadiidka iyo warshadaha kale oo si ballaaran loo isticmaalo sida isku dhafan oo ku habboon.
