Bir galvanized

Dhuumaha birta galvanizedwaxay u qaybsan yihiin tuubooyinka birta galvanized qabow iyo tuubooyinka birta galvanized kulul.Dhuumaha birta galvanized qabow waa la mamnuucay.Sanadihii 1960-meeyadii iyo 1970-meeyadii, dalalka horumaray ee adduunka ayaa bilaabay inay sameystaan ​​noocyo cusub oo tuubooyin ah waxayna si tartiib tartiib ah u mamnuuceen dhuumaha galvanized.Afar wasaaradood iyo guddiyo ay ka mid tahay Wasaaradda Dhismaha Shiinaha ayaa sidoo kale soo saaray dukumeenti sheegaya in tuubooyinka galvanized laga mamnuucay in loo isticmaalo tuubooyinka biyaha laga soo bilaabo 2000. Tuubooyinka biyaha qabow ee bulshooyinka cusub ee la dhisay ayaa dhif ah inay isticmaalaan tuubooyinka galvanized, iyo qaar ka mid ah biyaha kulul. Tuubooyinka beelaha qaarkood waxay isticmaalaan tuubooyinka galvanized.Tuubooyinka birta ah ee kulaylaha ah waxay leeyihiin codsiyo kala duwan oo kala duwan xagga ilaalinta dabka, awoodda iyo waddooyinka waaweyn.

Codsiyada

Tuubooyinka birta ah ee kulul ee kulul ayaa si weyn loogu isticmaalaa dhismaha, mishiinada, miinooyinka dhuxusha, kiimikooyinka, korontada, baabuurta tareenada, warshadaha baabuurta, jidadka waaweyn, buundooyinka, weelasha, goobaha ciyaaraha, mishiinada beeraha, mishiinada batroolka, mishiinada rajada, dhismaha aqalka dhirta lagu koriyo iyo kuwa kale warshadaha wax soo saarka.

Dhuumaha birta galvanized waa tuubo bir ah oo welded leh oo leh lakabka galvanized kulul ama korantada galvanized oo korka ah.Galvanizing waxay kordhin kartaa caabbinta daxalka ee tuubooyinka birta waxayna sii dheerayn kartaa nolosha adeegga.Tuubooyinka galvanized ayaa si weyn loo isticmaalaa.Marka laga soo tago in loo isticmaalo sida dhuumaha dhuumaha ee dareerayaasha cadaadiska hooseeya sida biyaha, gaaska, iyo saliidda, sidoo kale waxaa loo isticmaalaa sida tuubooyinka ceelasha saliidda iyo tuubooyinka saliidda ee warshadaha batroolka, gaar ahaan goobaha saliidda ee xeebaha, iyo kululeeyayaasha saliidda iyo qaboojiyaha. qalabka wax lagu karsado ee kiimikaad.Tuubooyinka qaboojiyaha, weeliyeyaasha saliidda dhaqida dhuxusha, iyo tuubooyinka tuulannada trestle, taageereyada tunnelyada miinada, iwm.

Hordhac faahfaahsan

Dheef kulultuubo galvanized

Tuubbada galvanized-ku-kulul waa inay ka dhigto birta dhalaalaysa inay la falgasho matrixka birta si ay u soo saarto lakab alloy ah, si matrixka iyo dahaarka la isku daro.Galvanization-ku-kulul waa in marka hore la guro tuubada birta.Si loo soo saaro oksaydhka birta ee dusha sare ee tuubada birta, ka dib marka la qaado, waxaa lagu nadiifiyaa haanta ammonium chloride ama zinc chloride aqueous ama xal isku dhafan oo ammonium chloride ah iyo zinc chloride, ka dibna loo diro gudaha qubays kulul oo kulul.Galvanizing-ku-kululku wuxuu leeyahay faa'iidooyinka daahan labbiska ah, dhejinta xooggan iyo nolosha adeegga dheer.Ku-kulul-ku-dirirkaDhuumaha birta galvanizedSubstrate-ku waxa uu maraa falcelin jidheed iyo kiimiko oo kakan oo leh xalka dhalaalka ah si uu u sameeyo lakab daaha zinc-birta u adkaysta oo leh qaab dhismeed is haysta.Lakabka daawaha waxaa lagu dhex daray lakabka zinc saafiga ah iyo substrate-ka tuubada birta, sidaas darteed waxay leedahay iska caabin adag oo daxalka ah.

Dhuumaha galvanized qabow

Dhuumaha galvanized qabow waa electro-galvanized, iyo qadarka galvanized waa mid aad u yar, kaliya 10-50g/m2.Iska caabbinta daxalka aad ayey uga duwan tahay tan tuubooyinka galvanized-ku-luqsiinaya.Si loo hubiyo tayada, inta badan soosaarayaasha tuubooyinka galvanized caadiga ah ma isticmaalaan korantada-galvanized (dhajinta qabow).Kaliya kuwa yaryar ee leh qalabka duugoobay ayaa isticmaala korantada, dabcan qiimahooduna waa raqiis.Wasaaradda dhismaha ayaa si rasmi ah u soo saartay amar ah in meesha laga saaro dhuumaha qaboojiya ee leh tignoolajiyada duugowday, isla markaana aan loo isticmaali karin tuubooyinka galvanized ee qabow ee biyaha iyo gaaska.Lakabka galvanized ee tuubada birta galvanized qabow waa lakabka korantada, iyo lakabka zinc wuxuu si madaxbanaan ula dahaadhay substrate-ka tuubada birta.Lakabka zinc waa dhuuban yahay, lakabka zinc wuxuu si fudud ugu dheggan yahay substrate-ka tuubada birta waana ay fududahay in la dhaco.Sidaa darteed, iska caabbinta daxalka ayaa liidata.Guryaha dhawaan la dhisay, waa ka mamnuuc in loo isticmaalo tuubooyinka birta galvanized qabow sida tuubooyinka biyaha.
