Dhuumaha birta galvanized guud ahaan waxay leedahay qiimaha macquulka ah ee wax ku ool ah suuqa. Marka la barbar dhigo daahannada kale ee birta ah ee caadiga ah, sida rinjiyeynta khaaska ah iyo daahan budada ah, galvanization waa mid aad u xoog badan oo xoog badan, taasoo keentay in kharashka bilowga ah sareeyo qandaraaslayaasha. Ka sokow, iyada oo ay ugu wacan tahay adkaysigeeda iyo guryaha ka-hortagga daxalka, dhuumaha birta galvanized ayaa dib loo warshadayn karaa oo dib loo isticmaali karaa, taas oo ilaa xad badbaadisay lacag badan inta lagu jiro shaqada dayactirka kadib.
Sida xirfadle soo saaraha tuubooyinka birta ee Shiinaha, waxaan jeclaan lahayn inaan kaa caawino inaad kala soocdo saddexda nooc ee ugu waaweyn ee qalabka birta ah ee galvanized si sax ah.
1) Dhuumaha birta galvanized kulul:
Habka galvanization-ka kulul waa meesha qayb hore loo sameeyay, tusaale ahaan saxan, wareeg, labajibbaaran ama tuubo bir leydi leh lagu rusheeyey qubeyska zinc. Dareen-celin ayaa ka dhacda inta u dhaxaysa birta iyo zinc inta lagu jiro wakhtiga qaybtu ku jirto qubayska zinc. Dhumucda dahaarka zinc waxaa saameeya dhowr arrimood, oo ay ku jiraan dusha sare ee tuubada birta, wakhtiga tuubada birta lagu rusheeyo qubeyska, ka kooban tuubada birta iyo sidoo kale xajmiga iyo dhumucda birta.
Mid ka mid ah faa'iidooyinka galvanizing qulqulka kulul ayaa ah in qaybta oo dhan ay daboolan tahay oo ay ku jiraan geesaha, alxanka, iwm. siinta ilaalinta daxalka oo dhan. Alaabta dhamaadka waxaa loo isticmaali karaa bannaanka dhammaan xaaladaha cimilada kala duwan. Waa habka ugu caansan ee galvanizing waxaana si ballaaran loogu isticmaalaa warshadaha dhismaha.
2) Dhuumaha birta hore loo galvanized:
Dhuumaha birta hore loo galvanized waxaa loola jeedaa dhuumaha birta ah ee la galvanized halka qaabka xaashida ah, ka hor inta aan la soo saarin. Pre-galvanization sidoo kale waxaa loo yaqaannaa galvanized-shiid kiimikaad, sababtoo ah xaqiiqda ah in xaashida birta lagu rogo zinc dhalaalaysa. Ka dib marka xaashida loo diro mishiinka si loo galvanized waa la gooyaa xajmiga oo dib ayaa loo rogaa. Dhumuc gaar ah ayaa lagu dabaqayaa xaashida oo dhan, tusaale ahaan horay loo galvanized Z275 birta waxay leedahay 275g halkii mitir laba jibaaran oo zinc ah. Mid ka mid ah faa'iidooyinka ay birta hore u galvanized ay ka badan tahay birta galvanized dip kulul waa in ay leedahay muuqaal wanaagsan.
Qalabka hore loo galvanized ayaa loo isticmaalaa noocyo kala duwan oo badeecooyin ah oo ay ku jiraan marin-biyoodka, dibnaha iyo kanaalada furan.
3) Dhuumaha birta ah ee korantada-galvanized:
Dhuumaha birta ee elektro-galvanized waxaa loola jeedaa codsashada jaakad zinc ah oo lagu shubay tuubada birta iyadoo la adeegsanayo kaydinta korantada. Dhuumaha birta ee elektro-galvanized ayaa faa'iido u leh in dhumucda daahan lagu xakameyn karo si madaxbannaan qaybaha gudaha iyo dibadda. Dhumucda dahaarka lagu dabaqay iyada oo loo marayo galvanization electro waa sax.
