Tuubbada birta ah ee korontada ku shaqeysata ee galka ah
Sharaxaada
Dhuumaha birta galvanized waa nooc ka mid ah tuubooyinka birta oo lagu dahaadhay lakabka zinc si looga ilaaliyo daxalka.Habka galvanization-ku wuxuu ku lug leeyahay gelinta tuubada birta ee qubeyska zinc la dhalaaliyay, kaas oo abuuraya xidhid u dhexeeya zinc iyo birta, samaynta lakab difaac oo korkiisa ah.
Dhuumaha birta galvanized ayaa caadi ahaan loo isticmaalaa codsiyo kala duwan oo kala duwan, oo ay ku jiraan tuubooyinka, dhismaha, iyo goobaha warshadaha.Way xoog badan yihiin oo waara, dahaarkooda galvanized waxay siinaya iska caabin heer sare ah ee miridhku iyo daxalka, taas oo ka dhigaysa mid ku habboon in loo isticmaalo meelaha bannaanka ah.
Dhuumaha birta galvanized waxay ku yimaadaan cabbirro iyo dhumucyo kala duwan si ay ugu habboonaadaan codsiyo kala duwan.Waxaa loo isticmaali karaa khadadka biyaha, xadhkaha gaasta, iyo codsiyada kale ee tuubooyinka, iyo sidoo kale taageerada qaab dhismeedka iyo deyrka.
Guryaha farsamaysan ee galvanized oo aan kala go 'lahayn
Qalabka farsamada ee birta waa in la hubiyo in tilmaame muhiim ah oo ka mid ah birta isticmaalka dhamaadka isticmaalka (qalabka farsamada), waxay kuxirantahay halabuurka kiimikada iyo daaweynta kulaylka birta.Heerarka birta, marka loo eego shuruudaha kala duwan, bixinta guryaha xajinta (xoogga xajinta, xoogga wax-soo-saarka ama dhererka dhibcaha) iyo adkaanta, adkaanta, shuruudaha isticmaalaha, heerkulka sare iyo hooseeya.

ISTICMAALKA
Dhuumaha birta Galvanized sida daahan dusha sare by galvanized waxaa si weyn looga codsadaa warshado badan sida dhismaha iyo dhismaha, makaanik (halka ay ka mid yihiin mishiinada beeraha, mishiinada batroolka, mishiinada rajada), warshadaha kiimikada, tamarta korontada, macdanta dhuxusha, baabuurta tareenka, baabuurta baabuurta, wadada weyn iyo buundada, goobaha ciyaaraha iyo wixii la mid ah.
Rinjiyeynta & Dahaarka
Xaaladda dusha sare ee tuubooyinka galvanized
Lakabka kowaad - Zinc elektrolytically leached (Zn) - wuxuu u shaqeeyaa sidii anode oo jawi daxalaysan marka hore wuu daxaliyaa birta salkana si toos ah ayaa looga ilaaliyaa daxalka.Dhumucda lakabka zinc wuxuu ahaan karaa inta u dhaxaysa 5 ilaa 30 micrometers (µm).
