Habka wax soo saarka
Wajiga I
Dhammaan gariiradda birta xariijimaha ah waa in la guraa oo la sumeeyaa si loo helo meel dhalaalaysa oo nadiif ah.
Wajiga II
1.Galvanizing-kulul: ka dib marka la qaado, waxaa lagu nadiifiyaa ammonium chloride ama zinc chloride aqueous ama ammonium chloride iyo zinc chloride oo isku qasan haanta dareeraha aqueous.Kadibna waxaa loo diraa haanta galvanizing-ka kulul ee galvanizing.
2.Galvanizing kulul: ka dib marka la qaado, waxaa lagu nadiifiyaa qubeyska ammonium chloride ama zinc chloride xal aqueous ama ammonium chloride iyo zinc chloride xal aqueous qasan, ka dibna loo diro qubeyska galvanizing ka dib foornada annealing joogto ah for galvanizing.
3.Galvanizing toos ah: ka dib marka la qaado, waxaa loo diraa foornada foornada joogtada ah ka dibna waxaa la geliyaa haanta galvanizing si ay u galvanizing.
Wajiga III
Ka dib markii birta xariijiinta la galvanized, waa in la duubaa oo lagu shubaa kaydinta.Lakabka galvanized wuxuu noqon karaa mid aan ka yarayn 50g/m2 marka loo eego shuruudaha macaamiisha, muunad kastana waa inuusan ka yarayn 48g/m2.
Birta xariijimaha galvanized ayaa guud ahaan loo isticmaalaa in laga sameeyo tuubooyinka birta, sida tuubooyinka aqalka dhirta lagu koriyo, tuubooyinka biyaha la cabbo, tuubooyinka kululaynta, iyo tuubooyinka gudbinta gaaska;Waxa kale oo loo isticmaali karaa dhismaha, warshadaha fudud, baabuurta, beeraha, xanaanada xoolaha, kalluumaysiga, ganacsiga iyo warshadaha kale.
Xarigga birta galvanized waxay muujinaysaa in warshadaha dhismaha inta badan loo isticmaalo soo saarista ka-hortagga daxalka warshadaha iyo saqafka dhismaha dhismaha madaniga ah, xadhkaha saqafka, iwm;Wershadaha iftiinka waxay u adeegsadaan soo saarista qolofka qalabka guryaha, qiiqa shiidaalka, weelka jikada, iwm.Beeraha, xanaanada xoolaha iyo kalluumaysiga waxaa inta badan loo isticmaalaa kaydinta cuntada iyo gaadiidka, agabka barafaysan ee hilibka iyo wax soo saarka biyaha iwm;Ganacsi ahaan, waxaa inta badan loo isticmaalaa sida kaydinta, gaadiidka iyo baakadaha qalabka;Qaab dhismeedka birta sandalwood bar (C, birta qaabka Z);Kel bir fudud, saqafka saqafka, iwm.

Isticmaalka Strip Steel Galvanized
Birta xariijimaha galvanized ayaa guud ahaan loo isticmaalaa in laga sameeyo tuubooyinka birta, sida tuubooyinka aqalka dhirta lagu koriyo, tuubooyinka biyaha la cabbo, tuubooyinka kululaynta, iyo tuubooyinka gudbinta gaaska;Waxa kale oo loo isticmaali karaa dhismaha, warshadaha fudud, baabuurta, beeraha, xanaanada xoolaha, kalluumaysiga, ganacsiga iyo warshadaha kale.Warshadaha dhismaha waxaa inta badan loo isticmaalaa in lagu soo saaro ka-hortagga daxalka warshadaha iyo saqafka dhismaha dhismaha madaniga ah, xadhkaha saqafka, iwm;Wershadaha iftiinka waxay u adeegsadaan soo saarista qolofka qalabka guryaha, qiiqa shiidaalka, weelka jikada, iwm.Beeraha, xanaanada xoolaha iyo kalluumaysiga waxaa inta badan loo isticmaalaa kaydinta cuntada iyo gaadiidka, agabka barafaysan ee hilibka iyo wax soo saarka biyaha iwm;Ganacsi ahaan, waxaa inta badan loo isticmaalaa sida kaydinta, gaadiidka iyo baakadaha qalabka;Qaab dhismeedka birta sandalwood bar (C, birta qaabka Z);Kel bir fudud, saqafka saqafka, iwm.
Astaamaha xariijimaha birta galvanized: strip steel galvanized waa nooc ka mid ah walxo ceeriin ah oo loo yaqaan (zinc) kaas oo lagu dahaadhay saxanka birta dhererka dheer iyo cidhiidhiga ah ee duubista qabow ama duubista kulul.Galvanizing Hot waxay leedahay faa'iidooyinka daahan labbiska ah, dhejinta xooggan iyo nolosha adeegga dheer.Falcelinta jirka ee adag iyo kiimikaad ee u dhexeeya substrate-ka tuubada birta galvanized-kuleelka ah iyo xalinta dhalaalaysa waxay sameeyaan daaha daaha zinc-birta u adkaysta oo leh qaab dhismeed is haysta.Lakabka daawaha waxa lagu dhex milmay lakabka zinc ee saafiga ah iyo substrate birta xariijimaha.Sidaa darteed, waxay leedahay iska caabin adag oo daxalka.Dhibcaha tayada ee birta galvanized-ka ah waa inay ahaadaan kuwo siman oo muuqaal ah, oo aan lahayn nodules zinc iyo burrs, iyo lacag caddaan ah;Dhumucda waa la kontarooli karaa, inta u dhaxaysa 5-107 μ Doorasho kasta oo m;Ma jiro isugeynta hydrogen iyo khatarta heerkulka, taas oo hubin karta in sifooyinka farsamada ee maaddadu ay tahay mid aan isbeddelin;Waxay bedeli kartaa hababka qaarkood ee u baahan galvanizing kulul;Iska caabbinta daxalka wanaagsan, tijaabada buufinta milixda dhexdhexaadka ah ilaa 240 saacadood;Iwm. birta xariifka ah, oo sidoo kale loo yaqaano xariijimaha birta, waxay u dhexaysaa 1300mm ballac ahaan, dhererkeeduna wax yar ayuu ka duwan yahay marka loo eego cabbirka gariiradda kasta.Birta xariijimaha guud ahaan waxaa lagu bixiyaa gariiradda, kaas oo leh faa'iidooyinka saxnaanta cabbirka sare, tayada dusha sare, habaynta fudud iyo badbaadinta alaabta.
Habka xirxirida: xirmo, kiis alwaax ah
