1. Durability & corrosion tsis kam
| Yam zoo | Spa - hreasing hlau yeeb nkab | Galvanized steel yeeb (piv txwv li, Astm A123) |
|---|---|---|
| Lub tshuab | Cov ntaub ntawv aKev tiv thaiv, adherent xeb patinauas blocks ntxiv corrosion. | Siv aKev fij Zinc Txheejuas corrodes ua ntej los tiv thaiv cov steel hlau. |
| Qhov zoo tagnrho ib puag ncig | Atmospheric raugNrog Cyclic ntub dej ntub / cov huab cua qhuav (nroog, kev lag luam, nyob deb nroog). | Ib puag ncig nrogKev pheej hmoo ntawm kev puas tsuajlossisRaws li noo noo(piv txwv li, xuas tes ua, fencing, dej raug). |
| Kev qaug zog | Kev ua tau zooNyob rau hauv tas li ntub dej, submerged, los yog siab -}} ntsev txaws / tshuaj tsuag zones. Lub patina tsis tuaj yeem ruaj khov. | Cov Zinc Txheejtuaj yeem hnav tau debLos ntawm kev puas tsuaj, ua rau cov hlau. Nws tuaj yeem ua tsis tau sai dua nyob rau hauvAcidic los yog cov ib puag ncig ib puag ncig. |
| Lub neej | 50+ xyoonyob rau hauv cov atmospheres. PATINE txuas ntxiv nws tus kheej. | 15-25 xyoosYog muaj ntau, nyob ntawm zinc txheej tuab tuab (piv txwv li G60, G90) thiab ib puag ncig. |
Durability vertdict:Spa - h feem ntauNtau ruaj khov nyob rau hauv qhib atmospheric extrosuresVim nws tus kheej -} rov qab txuas patina. Galvanized steel yog ntau ntxiv rau ntau yam ntawm ib puag ncig ib puag ncig, tshwj xeeb tshaj yog qhov twg abruction los yog ib qho kev tiv thaiv, tab sis nws cov kev tiv thaiv yog finite.
2. Tus nqi {- ua tau zoo (thawj thiab lub neej. Lub neej- lub voj voog tus nqi)
Qhov no yog qhov tseem ceeb tshaj plaws thiab qhia tawm cov tub ntxhais sib txawv ntawm ob txoj kev xaiv.
| Tus nqi hom | Spa - hreasing hlau yeeb nkab | Galvanized steel yeeb nkab |
|---|---|---|
| Thawj cov khoom siv | Siab dua(20%- 50}% ntau dua galvanized). Cov ntsiab lus alloying (CU, CR, NI) nce tus nqi. | Qis dua.Cov khoom siv hauv paus yog pheej yig carbon hlau, thiab cov txheej txheem galvanizing yog kev lag luam zoo. |
| Txhim Kho & Fabrication | Zoo sib xws. Yuav tsum tau vuam cov txheej txheem tsim nyog rau cov hluav taws hlau. | Zoo sib xws. Yooj yim rau weld tab sis yuav tsum tau tshaj tawm - Weld kho rau cov chaw puas. |
| Txij Nkawm Cov Nqi | Tsawg kawg nkaus.Tsim los uaTxij Nkawm - dawbCov. Tsis tas yuav muaj kev pleev xim lossis rov ua haujlwm. | Siab dua.Yuav kawg xav tauRov pleev xim lossis regalvanizingTom qab zinc txheej depletes (15-25 xyoos). |

3. Aesthetic & Lwm Yam Kev Txiav Txim
| Yam | Spa - hreasing hlau yeeb nkab | Galvanized steel yeeb nkab |
|---|---|---|
| Kev tshwm sim | Rust - zoo li, earthy xim av(patina). prized rau kev hais kom rov hais dua. Blends nrog xwm. | Ci iab, silvery - greythaum tshiab; dulls rau matte grey dhau sijhawm. Ntau saib. |
| Cuam tshuam ib puag ncig | Tsis tas yuav rov qab pleev xim rov ua dua ntev li ntev - lub sij hawm vocs thiab pov tseg. Siab rov ua dua tshiab. | Galvanizing cov txheej txheem yog lub zog - heev. Zinc tsuas thiab kev ua cov kev cuam tshuam ib puag ncig. |
| Dej ntws | Thawj zaug xeb dejMuaj peev xwm stain ncig qhov chaw (piv txwv li, pob zeb ua) rau thawj ob peb xyoos. | Zinc Drunofftuaj yeem tshwm sim, uas yuav raug tswj hwm hauv qee thaj chaw ib puag ncig. |
