Dab tsi yog qhov tsis zoo ntawm steel phaj?
Thaum nws los txog rau kev tsim kho cov ntaub ntawv, steel phaj feem ntau pom tias yog qhov kev xaiv ruaj khov thiab ruaj khov. Nws lub zog thiab ntau yam tau ua rau nws muaj kev xaiv nrov hauv ntau yam lag luam. Txawm li cas los xij, zoo li lwm yam khoom siv, steel phaj kuj muaj nws qhov ncaj ncees ntawm qhov tsis zoo. Hauv tsab xov xwm no, peb yuav tham txog qee qhov tsis zoo ntawm kev siv steel phaj hauv kev tsim kho.
1. Corrosion
Ib qho ntawm qhov tsis zoo tshaj plaws ntawm cov phaj steel yog nws qhov tsis zoo rau corrosion. Thaum raug cov dej noo thiab cov pa oxygen, cov hlau nyiam xeb dhau sijhawm. Qhov no tuaj yeem txo qhov kev ncaj ncees ntawm cov qauv thiab cuam tshuam nws lub zog tag nrho. Txhawm rau txo qhov teeb meem no, ntau txoj hauv kev xws li galvanization lossis txheej txheej tuaj yeem siv tau. Txawm li cas los xij, cov kev kho no tuaj yeem ntxiv cov nqi ntxiv thiab kev saib xyuas rau qhov project.
2. Nyhav
Hlau phaj kuj hnyav piv rau lwm yam ntaub ntawv xws li txhuas lossis ntoo. Qhov no tuaj yeem ua rau muaj teeb meem thaum thauj thiab teeb tsa. Qhov hnyav ntawm steel phaj yuav xav tau cov cuab yeej tshwj xeeb lossis tshuab rau kev tuav, ua kom cov nqi tag nrho ntawm qhov project. Tsis tas li ntawd, qhov hnyav ntawm steel phaj txwv nws txoj kev siv hauv qee yam kev siv uas nyiam cov khoom siv sib dua.
3. Tus nqi
Txawm hais tias steel phaj paub txog nws lub zog thiab ruaj khov, nws feem ntau kim dua piv rau lwm yam khoom siv. Tus nqi ntawm kev yuav khoom, kev ua, thiab fabricating steel phaj tuaj yeem ua tau ntau yam, tshwj xeeb tshaj yog rau cov haujlwm loj. Tsis tas li ntawd, tus nqi ntawm cov hlau yog nyob rau hauv kev lag luam hloov pauv, ua rau nws nyuaj rau kwv yees thiab tswj cov nqi tsim nyog kom raug.
4. Kev cuam tshuam ib puag ncig
Kev tsim cov hlau phaj cuam tshuam nrog kev ua cov hlau ore, uas muaj kev cuam tshuam rau ib puag ncig. Kev rho tawm thiab ua cov khoom siv raw siv lub zog thiab tso tawm cov pa hauv tsev cog khoom. Tsis tas li ntawd, steel ntau lawm tsim cov khoom pov tseg ntau, xws li slag thiab emissions. Cov kev txhawj xeeb ntawm ib puag ncig no tau ua rau kev tshawb nrhiav thiab tsim cov khoom siv nrog cov pa roj carbon tsawg dua.
5. Hluav taws kub tsis kam
Thaum hlau paub txog nws lub zog, nws tsis muaj qhov hluav taws kub tsis kam. Thaum raug kub siab, steel phaj tuaj yeem poob sai sai rau nws cov qauv kev ruaj ntseg thiab tawg. Qhov kev txwv no tsim nyog suav nrog kev ntsuas hluav taws xob los txhim kho hluav taws kub. Cov kev ntsuas no suav nrog cov txheej txheem hluav taws kub los yog qhov sib ntxiv ntawm cov khoom siv hluav taws xob, uas tuaj yeem ntxiv qhov nyuaj thiab cov nqi rau kev tsim kho.
6. Thermal conductivity
Hlau phaj muaj cov thermal conductivity siab, uas txhais tau tias nws tuaj yeem hloov cov cua sov sai. Qhov no tuaj yeem ua rau muaj teeb meem xws li poob cua sov, condensation, lossis thermal bridging hauv qhov project tsim. Kev rwb thaiv tsev kom zoo thiab thermal so yuav tsum tau txo cov teeb meem no, uas tuaj yeem ua rau tus nqi tag nrho thiab qhov nyuaj ntawm qhov project.
7. Txwv tsis pub yooj yim
Hlau phaj yog cov khoom siv nruj, uas txwv tsis pub nws yooj yim rau qee yam kev siv. Nws tsis tuaj yeem yooj yim molded lossis zoo li lwm yam khoom xws li ntoo lossis yas. Qhov tsis muaj qhov hloov pauv no tuaj yeem yog qhov tsis zoo thaum tsim cov qauv nkhaus lossis cov qauv sib txawv uas xav tau cov duab tshwj xeeb. Nyob rau hauv cov ntaub ntawv no, lwm yam ntaub ntawv los yog ntxiv fabrication txheej txheem yuav tsum tau.
8. Magnetism
Hlau yog cov khoom sib nqus, uas tuaj yeem ua tau zoo thiab qhov tsis zoo nyob ntawm qhov project yuav tsum tau ua. Qee zaum, cov khoom sib nqus ntawm cov hlau phaj tuaj yeem cuam tshuam nrog kev ua haujlwm ntawm cov khoom siv rhiab lossis cov khoom siv hluav taws xob. Qhov no yuav xav tau kev tiv thaiv ntxiv lossis kev xaiv cov ntaub ntawv tsis sib nqus, ua rau kom qhov nyuaj thiab tus nqi ntawm qhov project.
9. Kev tu
Hlau phaj xav tau kev saib xyuas tsis tu ncua los tswj nws cov qauv kev ncaj ncees thiab tiv thaiv corrosion. Qhov kev saib xyuas no yuav suav nrog kev tshuaj xyuas, tu, thiab rov ua dua cov txheej txheem tiv thaiv. Kev ua tsis tau raws li kev saib xyuas txaus tuaj yeem ua rau muaj kev puas tsuaj sai ntawm cov phaj steel thiab cuam tshuam kev nyab xeeb ntawm cov qauv. Cov kev tu ncua tsis tu ncua tuaj yeem ntxiv rau tus nqi mus sij hawm ntev ntawm qhov project.
10. Kev txwv kev zoo nkauj
Hlau phaj feem ntau pom tias yog cov khoom lag luam lossis cov khoom siv hluav taws xob, uas yuav tsis zoo nkauj rau qee tus neeg. Nws tsis muaj qhov zoo nkauj thiab sov so ntawm cov ntaub ntawv xws li ntoo lossis pob zeb. Thaum cov qauv tsim vaj tsev tuaj yeem koom ua ke steel phaj muaj tswv yim, nws yuav tsis haum rau lub ntsiab lus zoo nkauj hauv qee qhov haujlwm. Qhov kev txwv no yuav xav tau cov khoom siv kho kom zoo nkauj lossis cladding ntxiv, ntxiv rau tag nrho cov nqi thiab qhov nyuaj ntawm qhov project.
** Hauv kev xaus, steel phaj, txawm tias nws muaj ntau qhov zoo, tsis yog tsis muaj nws qhov tsis zoo. Qhov cuam tshuam rau corrosion, qhov hnyav, tus nqi, ib puag ncig cuam tshuam, hluav taws kub tsis kam, thermal conductivity, txwv tsis pub, kev sib nqus, kev saib xyuas, thiab cov kev txwv zoo nkauj yog qhov tsis zoo uas yuav tsum tau xav txog thaum xaiv cov hlau phaj ua cov khoom siv. Txawm li cas los xij, nrog kev npaj, tsim, thiab kev saib xyuas kom zoo, cov teeb meem no tuaj yeem txo qis, tso cai rau cov phaj hlau txuas ntxiv yog qhov kev xaiv tseem ceeb rau ntau daim ntawv thov kev tsim kho.**
