Taw qhia
GI steel, uas sawv cev rau galvanized hlau hlau, yog ib hom hlau uas tau dhau los ua cov txheej txheem galvanizing los tiv thaiv corrosion. Hom hlau no muaj ntau yam kev siv hauv ntau yam kev lag luam, suav nrog kev tsim kho, tsheb, thiab kev tsim khoom. Hauv tsab xov xwm no, peb yuav ua tib zoo saib seb GI steel yog dab tsi thiab qhov sib txawv ntawm nws siv.
GI steel yog dab tsi?
GI steel yog ib daim ntawv ntawm cov hlau uas tau coated nrog ib txheej ntawm zinc los tiv thaiv nws ntawm xeb thiab corrosion. Cov txheej txheem no yog hu ua galvanization thiab koom nrog dipping cov hlau mus rau hauv da dej kub ntawm molten zinc, uas tsim kom muaj kev sib raug zoo ntawm ob lub hlau, ua rau nws nyuaj rau xeb thiab corrosion.
Lub thickness ntawm zinc txheej tuaj yeem sib txawv, thiab cov txheej tuab dua, cov hlau tsis xeb yuav ntau dua. GI steel yog ib qho kev xaiv pheej yig uas yog ob qho tib si ruaj khov thiab siv tau ntev, ua rau nws muaj kev xaiv zoo rau ntau yam kev siv.
Kev siv cov GI steel **
** Kev tsim kho kev lag luam
Ib qho tseem ceeb ntawm kev siv GI steel yog nyob rau hauv kev tsim kho kev lag luam. GI hlau feem ntau yog siv rau vov tsev thiab sab hauv tsev, vim zinc txheej muab kev tiv thaiv zoo los ntawm cov khoom. Hom hlau no kuj yog siv rau kev tsim qauv, xws li rau kab teeb thiab kab, vim nws muaj zog thiab tuaj yeem txhawb nqa hnyav.
Tsis tas li ntawd, GI steel yog siv rau laj kab, rooj vag, thiab lwm yam khoom siv. Nws cov kav ntev thiab kev ua haujlwm ntev ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim kho mus ntev.
Automotive kev lag luam
GI steel kuj tau siv dav hauv kev lag luam tsheb. Cov hlau yog siv los tsim lub cev vaj huam sib luag, chassis, thiab lwm qhov chaw ntawm lub tsheb, nrog rau cov mufflers thiab tso pa tawm.
Cov zinc txheej ntawm GI steel muab cov txheej txheem tiv thaiv uas pab tiv thaiv xeb thiab xeb, kom ntseeg tau tias lub tsheb tseem nyob hauv qhov zoo rau xyoo. Tsis tas li ntawd, GI steel yog qhov hnyav, ua rau nws yog ib qho kev xaiv zoo rau cov tuam txhab tsheb uas tab tom nrhiav kom txo qhov hnyav ntawm lawv lub tsheb los txhim kho roj efficiency.
Kev tsim khoom lag luam
Kev lag luam tsim khoom kuj tseem siv dav siv GI steel. Cov hlau feem ntau yog siv los tsim cov khoom siv, xws li tub yees, tshuab ntxhua khaub ncaws, thiab tshuab ziab khaub ncaws. Lub zinc txheej pab tiv thaiv cov khoom siv los ntawm xeb thiab corrosion, kom ntseeg tau tias lawv kav ntev dua.
GI steel kuj tseem siv rau kev tsim cov kav dej thiab cov kav dej, uas yog siv hauv kev lag luam roj thiab roj, nrog rau cov kav dej. Cov hlau tsis xeb-tiv taus ua rau nws yog qhov kev xaiv zoo nkauj rau cov ntawv thov no, vim nws ua kom cov kav dej thiab cov kav dej yuav kav ntev dua thiab yuav tsum tau saib xyuas tsawg dua.
Qhov zoo ntawm GI steel
Muaj ntau qhov zoo rau kev siv GI steel hauv ntau daim ntawv thov:
- rust-resistant: zinc txheej ntawm GI steel pab tiv thaiv nws los ntawm xeb thiab corrosion, kom ntseeg tau tias nws kav ntev dua thiab yuav tsum tau saib xyuas tsawg dua.
- Durable: GI steel yog cov khoom siv muaj zog thiab siv tau ntev uas tuaj yeem tiv taus cov khoom hnyav thiab huab cua hnyav, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev tsim kho.
- Nqis: GI steel yog qhov kev xaiv them nqi uas muaj dav thiab yooj yim rau qhov chaw.
- Lub teeb yuag: Txawm tias nws lub zog, GI steel yog qhov sib sib zog nqus, ua rau nws muaj kev xaiv zoo rau ntau qhov kev lag luam, suav nrog tsheb thiab kev tsim kho.
Disadvantages ntawm GI hlau
Thaum GI steel muaj ntau qhov zoo, muaj qee qhov tsis zoo los xav txog:
- Kev xaiv xim txwv: Cov zinc txheej ntawm GI steel feem ntau yog nyiaj lossis grey xim, uas tej zaum yuav tsis tsim nyog rau qee qhov kev siv.
- Yooj yim rau khawb: zinc txheej ntawm GI hlau tuaj yeem khawb tau yooj yim, uas tuaj yeem ua rau xeb thiab xeb ua rau hauv qab.
- Deg imperfections: GI steel tej zaum yuav muaj cov imperfections nto, xws li pob los yog me me blemishes, uas yuav cuam tshuam rau nws cov tsos.
- Tej zaum yuav tsis haum rau qhov chaw huab cua: Txawm hais tias GI hlau ruaj khov thiab siv tau ntev, nws yuav tsis haum rau qhov chaw hnyav heev, xws li thaum muaj cov tshuaj corrosive heev.
