Cov hlau carbon, galvanized, thiab stainless hlau yog peb hom hlau uas siv ntau tshaj plaws hauv kev lag luam thiab kev tsim kho. Txhua hom muaj cov khoom sib txawv, kev ua tau zoo, thiab tus nqi. Kev xaiv qhov yog yuav pab koj sib npaug qhov zoo, peev nyiaj, thiab lub neej ntawm txoj haujlwm.
1. Cov Hlau Carbon Kub Dov- Muaj zog thiab muaj kev lag luam zoo
Cov Khoom Xyaw: Hlau + carbon (0.05%–1.0%)
Nta: Muaj zog heev, yooj yim ua, pheej yig
Qhov tsis zoo: tsis kam rau corrosion, yooj yim xeb
Zoo tshaj plaws rau: Siv sab hauv tsev, chaw qhuav, khi kev tsim kho, cov caij nplooj ntoos hlav, cov ntsia hlau, cov ntaub thaiv laj kab
Lub neej: 1-3 xyoos hauv tsev
2. Cov Hlau Hlau Galvanized Carbon Siab- Tus nqi sab nraum zoov zoo tshaj plaws
Muaj pes tsawg leeg: Cov hlau carbon + zinc txheej (electro lossis hot-dip)
Cov yam ntxwv: Ua kom cov hlau muaj zog + ntxiv kev tiv thaiv corrosion
Tsis Muaj Zog: Txheej zinc yuav hnav; cov hlau hauv paus xeb yog tias raug
Qhov zoo tshaj plaws rau: Cov laj kab sab nraum zoov, cov teeb meem kev loj, kev khi tsev cog khoom, cov xov hluav taws xob
Lub neej: 5-20 xyoo sab nraum zoov (kub-dip nyiam)
3. Hlau Stainless- Kev Tiv Thaiv Kev Ruaj Khov Mus Ib Txhis
Muaj pes tsawg leeg: Chromium ≥10.5% (304, 316, thiab lwm yam)
Nta: Xeb-pov thawj, kua qaub & ntsev resistant, huv si tsos, lub neej ntev
Qhov Tsis Muaj Zog: Tus nqi siab dua (2–3x carbon steel)
Qhov zoo tshaj plaws rau: Cov ntug dej hiav txwv, tshuaj lom neeg, dej hiav txwv, khoom noj & kev siv kho mob
Lub neej: 50+ xyoo, tsis muaj kev saib xyuas
