Qodobbada saameeya dhumucda dahaarka birta ee zinc waxaa inta badan ah: Halabuurka birta ee shabagga birta, qallafsanaanta dusha sare ee shabaglaha birta, nuxurka iyo qaybinta walxaha firfircoon ee Silicon iyo fosfooraska ee shabagga birta, culeyska gudaha ee birta birta, cabbirrada joomatari ee birta qashinka birta, iyo geeddi-socodka galvanizing-kulul-kulul ee shabaglaha birta. Heerarka galvanizing kulul ee caalamiga ah iyo Shiinaha ee hadda jira ayaa loo qaybiyaa qaybo iyadoo loo eegayo dhumucda saxanka. Celceliska dhumucda iyo dhumucda maxalliga ah ee daahan zinc waa inay gaaraan dhumucda u dhiganta si loo go'aamiyo waxqabadka ka-hortagga daxalka ee dahaarka zinc. Waqtiga loo baahan yahay si loo gaaro dheellitirka kulaylka iyo sinnaanta sarrifka zinc-birta ee birta birta ah ee birta ah ee dhumucdeedu kala duwan tahay way ka duwan tahay, dhumucda dahaarka la sameeyay ayaa sidoo kale ka duwan. Celceliska dhumucda dahaarka ee heerka waa khibrad wax soo saar warshadeed oo ku salaysan habka galvanizing ee kor ku xusan, dhumucdiisuna waxay tahay khibrad khibradeed oo loo baahan yahay si loo tixgeliyo qaybinta sinnaanta ee dhumucda daahan zinc iyo shuruudaha caabbinta daxalka ee daahan. Sidaa darteed, heerka ISO, heerka ASTM-ka Mareykanka, halbeegga JS ee Japan iyo halbeegga Shiinaha waxay leeyihiin shuruudo xoogaa ka duwan dhumucda dahaarka zinc, kuwaas oo la mid ah. Marka loo eego qodobbada galvanizing-kulul-kulul GB B 13912-2002 ee Jamhuuriyadda Dadka Shiinaha. Heerarka dahaarka zinc ee alaabta shaaha ee birta galvanized ee kulul waa sida soo socota: Wixii kuleyl ah ee birta galvanized birta leh dhumucdiisuna waxay ka weyn tahay ama le'eg tahay 6mm, celceliska dhumucda dahaarka zinc ee shabagga galvanized birta kulul waa inuu ka weyn yahay 85 microns, iyo dhumucda maxalliga ah waa inay ka weyn tahay 70 microns. Shabagyada birta galvanized-kuleelka leh ee dhumucdiisu ka yar tahay 6mm iyo ka weyn 3mm, celceliska dhumucda dahaarka zinc ee shabagga galvanized birta kulul waa in ay ka weyn tahay 70 microns, iyo dhumucda maxalliga ah waa in ay ka weyn tahay 55 microns. Shabagyada birta galvanized-kuleelka leh ee dhumucdiisu ka yar tahay 3mm iyo ka weyn 1.5mm, celceliska dhumucda dahaarka zinc ee shabagga galvanized birta kulul waa in uu ka weyn yahay 55 microns, iyo dhumucda maxalliga ah waa in ay ka weyn tahay 45 microns.
Doorka iyo saamaynta kuleelka galvanizing dhumucdiisuna waxay tahay
Dhumucdiisuna waxay daahan galvanized kulul-muquufin on shabaggeedii birta ayaa go'aamisa waxqabadka anti-daxalka ee shabaggeedii birta. Isticmaalayaasha waxay dooran karaan dhumucda daahan zinc ka sare ama ka hooseeya heerka. Way adag tahay in la helo dahaarka dhumuc weyn ee wax soo saarka warshadaha ee shabagyada birta khafiifka ah oo leh dusha siman oo ka yar 3mm. Intaa waxaa dheer, dhumucda dahaarka zinc ee aan u dhigmin dhumucda saxanka sharoobada birta waxay saameyn doontaa xoogga isku xirnaanta ee u dhexeeya dahaarka iyo substrate-ka iyo tayada muuqaalka muuqaalka. Daruur qaro weyni waxay keeni doontaa in dahaarka uu u muuqdo mid qallafsan oo ay fududahay in la fujiyo. Shabaglaha birta ah ee dahaaran uma adkeysan karaan isku dhaca inta lagu jiro gaadiidka iyo rakibidda. Haddii ay jiraan waxyaabo badan oo firfircoon oo silikoon iyo fosfooraska ah oo ku jira alaabta ceeriin ee qashinka birta, sidoo kale aad bay u adagtahay in la helo dahaarka khafiifka ah ee wax soo saarka warshadaha. Tani waa sababta oo ah nuxurka silikoon ee birta waxay saamaysaa habka koritaanka ee lakabka daawaha ee u dhexeeya zinc iyo birta, taas oo keeni doonta (, wajiga zinc-birta lakabka daaha si degdeg ah u koraan iyo (ilaa dusha ee daahan, taasoo keentay in daahan qallafsan oo caajis ah dusha daahan, samaynta daahan cawl leh adhesion liidata. Sidaa darteed, sida kor looga hadlay, waxaa jira hubaal la'aan in koritaanka lakabka birta ah ee daahan si ay u helaan si degdeg ah lakabka galvanized ah oo gaar ah. wax soo saarka
