Thaum nws los txog rau lub tshuab nqus dej rau kev tsim kho, tso dej, roj faib, thiab txoj haujlwm tsim khoom, kev xaiv ntawm cov khoom yog qhov tseem ceeb. Ob qho kev xaiv sib piv yogDub Hlau Kavthiabgalvanized kavCov. Thaum lawv yuav zoo ib yam li thawj zaug muag, lawv txawv nyob rau hauv muaj pes tsawg leeg, txheej, ua tau zoo, thiab kev siv. Nkag siab cov kev sib txawv no ua kom cov kev txiav txim siab zoo dua rau kev ua haujlwm tau zoo, kev nyab xeeb, thiab tus nqi- ua hauj lwm zoo.
Dab tsi yog dub hlau kav?
Dub hlau kav hlau yog ua los ntawm cov hlau me me los yog qis}}}} Cov npe ntawm lawv qhov tsaus, uas los ntawm cov hlau oxide txheej ntawm lawv cov npoo. Cov kav dej no tsis muaj ib qho ntxiv ntxiv thiab yog li ntau tau nquag nquag corrosion thaum raug rau ya raws. Txawm li cas los xij, lawv qhov tsis muaj xwm txheej ua rau lawv muaj yooj yim rau weld thiab ua haujlwm nrog, uas yog vim li cas lawv tau siv dav hauv hluav taws sprinkler tshuab, ntuj thauj khoom, thiab qee qhov kev lag luam.
Vim tias dub hlau kav kav tsis muaj zinc lossis lwm yam txheej ci, lawv tsis haum rau kev thauj cov dej haus. Txoj kev pheej hmoo ntawm xeb tsim hauv cov yeeb nkab tuaj yeem ua rau cov dej tsis zoo thiab ua rau lub sijhawm dhau los.
Dab tsi yog galvanized kav?
Galvanized kav yog cov kav dej steel coated nrog ib txheej ntawm zinc los muab corrosion tsis kam. Cov txheej txheem galvanization, feem ntau kub- dip txheej adheres rau cov yeeb nkab sab, tiv thaiv nws los ntawm xeb thiab txuas nws lub neej pabcuam.
Tau ntau xyoo, cov kav dej galvanized tau siv nyob rau hauv cov tshuab xa dej rau tsev thiab vaj tse. Txawm li cas los xij, vim muaj peev xwm zinc cav, ntxhia kev pheej hmoo ntawm cov khoom noj txhuas hauv cov laus, lawv tsis tau pom zoo rau cov dej ntim khoom dua. Hloov chaw, galvanized kav yog tam sim no feem ntau siv nyob rau hauv cov tsheb ciav hlau sab nraum zoov, laj kab, scaffolding, thiab cov ntawv thov uas muaj zog tiv thaiv kev siv huab cua yog qhov tseem ceeb.
Qhov sib txawv ntawm cov hlau hlau dub thiab cov kav dej galvanized
Cov lus hauv qab no qhia txog qhov sib txawv tseem ceeb ntawm cov kav hlau dub dub thiab kav galvanized:
| Yam zoo | Dub Hlau Kav | Galvanized kav |
|---|---|---|
| Nto tas | Tsaus ntuj, Matte los ntawm hlau oxide | Ci iab, Nyiaj los ntawm Zinc Txheej |
| Corrosion Kuj | Tsawg, nquag mus rau xeb | Siab, zinc txheej tiv thaiv tiv thaiv xeb |
| Hwj txwv | Yooj Yim Rau Weld | Ntau nyuaj vim zinc txheej |
| Cov Kev Siv Cov Ntawv Siv | Cov kab roj, hluav taws sprinkler cov tshuab, cua sov | Sab nraum zoov qauv, laj kab, scaffolding |
| Siv dej siv | Tsis haum | Yav tas los siv, tam sim no feem ntau zam |
| Lub neej | Luv luv yam tsis muaj kev tiv thaiv kev tiv thaiv | Ntev dua nrog zinc tiv thaiv |
| Tus nqi | Qis dua upfront tus nqi | Me ntsis siab dua vim galvanization |
Qhov kev sib piv no tau qhia meej meej tias txhua hom yeeb nkab muaj nws cov txiaj ntsig thiab cov kev txwv thiab kev txwv nyob ntawm kev siv.
Cov ntawv thov thiab haum xeeb
- Dub Hlau KavFeem ntau haum rau kev tua cov pa roj thiab rau cov tshuab tiv thaiv hluav taws uas yog qhov kev txhawj xeeb tsawg tab sis weldability thiab nqi ua ntej. Lawv tseem nrov nyob hauv qee cov ntawv thov cua sov.
- Galvanized kavYog qhov kev xaiv zoo dua rau cov txheej txheem sab nraum zoov uas raug ua kom muaj dej noo yog siab. Lawv tau txais kev pabcuam ntev ntev hauv fencing, scaffolding, thiab txhawb kev coj ua.
Txawm li cas los xij, tsis yog xim dub tsis zoo tagnrho rau cov kav dej galvanized yog qhov chaw uas cov khoom siv yas xws li PEX thiab PVC muaj ntau siv.
Tag
Lub ntsiab sib txawv ntawm dub hlau kav dej thiab cov kav dej galvanized nyob hauv lubmuaj ntawm cov txheej zinc, uas ua rau galvanized kav ntau tiv taus rau xeb thiab haum rau kev siv sab nraum zoov. Dub hlau kav hlau, txawm tias muaj kev yooj yim rau kev xeb, yog qhov yooj yim rau weld thiab dav siv nyob rau hauv cov roj kab thiab hluav taws kev tiv thaiv.
NtawmHUAYANG STEEFF YEEB NKAB, peb muab cov pa yeeb nkab hlau, suav nrog cov kav dej dub steel, thiab cov kav dej galvanized, thiab cov kav dej galw, ua kom pom kev sib ntsib sib txawv thiab kev tsim kho. Los ntawm kev nkag siab txog qhov sib txawv ntawm ob cov ntaub ntawv no, kws ua choj thiab cov lag luam tuaj yeem xaiv feem ntau txoj kev xaiv rau lawv txoj haujlwm.
