1.Yog li cas yog cov ntsiab lus tseem ceeb ntawm kev ua kom lub tsev txhim kho kev txhim kho lub tsev?
Cov qhabnias / qhabnias: Cov khoom qub, cov khoom siv tes ua, cov qauv thiab cov ntaub ntawv keeb kwm yuav tsum tau tshwj xeeb thiab siv rau qhov zoo tshaj plaws tau. Cov ntaub ntawv tshiab yuav tsum muaj tsawg thiab pom tau tias (kev ua txhaum kev thim rov qab).
Kev thim rov qab: qhov chaw tshiab yuav tsum muaj peev xwm muab tshem tawm lossis hloov tshiab nyob rau yav tom ntej tsis muaj kev puas tsuaj, thiab rov qab ua ntej kev cuam tshuam. Tsawg tsawg kev cuam tshuam: tsuas yog tsim nyog thiab txaus kev cuam tshuam yuav tsum tau nqa tawm, zam kev kho ntau dhau.
Kev sib piv: Cov ntaub ntawv tshiab yuav tsum yog lub cev, tshuaj thiab kev ua kom zoo tshaj nrog cov ntaub ntawv qub kom tsis txhob muaj kev puas tsuaj.
Qhov ruaj khov: Cov ntaub ntawv tshiab yuav tsum muaj lub neej txaus los txo qhov xav tau ntawm kev cuam tshuam ntau zaus nyob rau yav tom ntej.
Nco ntsoov: qhov chaw tshiab yuav tsum tau qhov txawv ntawm cov keeb kwm ntu (feem ntau ua tiav los ntawm kev pom sib txawv).
2.Qhov dab tsi yog cov yam ntxwv ntawm lub galvanized steel?
Qhov Zoo:
Corrosion Kuj: Cov Zinc Txheej Muaj Kev Tiv Thaiv Kev Txhaum Cai, thiab nws cov kev pabcuam lub neej ntev npaum li cas ntau dua li cov pa roj carbon hlau dav.
Lub zog: tus hlau nws tus kheej muaj lub zog siab thiab haum rau ntu uas yuav tsum tau siv zog lossis hnyav.
Cov nyiaj txiag ntxiv: piv nrog kev txhim kho corrosion-resistant hlau xws li stainless hlau thiab titanium alloy, galvanized steel muaj tus nqi qis dua. Machinability: Tau yooj yim txiav, weld (xyuam xim rau cov cawv txheej zinc txheej), thiab daim ntawv.
Tsis zoo
Cov tsos mob: grey lossis crystal-qauv-qauv yog sib xws nrog cov khoom siv xws li ntoo, pob zeb, tooj, thiab lwm yam pom hauv cov tsev qub. Nws yog kev pom zoo.
Tej zaum corrosion: thaum cov hlau galvanized los ua kev sib cuag nrog cov hlau nrog ntau dua cov khoom siv hluav taws xob (ntsev), nws yuav ua kom muaj zog ntawm cov hlau uas muaj xeb (xws li anode). Qhov no yog kev pheej hmoo siab hauv kev sib tw ntawm ntau cov hlau uas muaj nyob hauv cov tsev qub.
Zinc Txheej Kev Siv Khoom Siv thiab Kev Corrosion ntxiv: Cov txheej zinc txheej yog ib qho kev siv tau. Thaum nws tau sab sab, cov pa roj carbon hlau nyob sab hauv yuav pib corrode, thiab cov xeb) yuav ua rau muaj kev puas tsuaj rau ib puag ncig Masonry thiab ntoo, thiab tsim cov kuab paug tsis zoo.
Compatibility nrog Ntoo: Thaum cov hlau galvanized los ua kev sib christic acid thiab actic acid) yuav ua kom muaj cov txheej corrosion. Nyob rau tib lub sijhawm, cov khoom hlau yuav tabkaum lub ntuj ua pa thiab qhuav-ntub kev hloov ntoo, uas yuav ua rau lwj hauv cheeb tsam hauv zos. Kev tiv tauj ntev ntawm cov fasteners (xws li galvanized rau tes) thiab ntoo yog ib qho teeb meem ntau.
Kev hloov kho cov teeb meem: galvanized steel txheej uas yog welded lossis siv tshuaj txawb lossis tsis yooj yim kom tshem tawm yam tsis muaj kev puas tsuaj. Cov Cheebtsam sib txawv yog qhov yooj yim kom tshem tawm, tab sis yuav tawm qhov lossis kev puas tsuaj.
Tsis sib haum nrog cov txheej txheem keeb kwm: galvanizing yog ib qho txheej txheem niaj hnub no, cam khwb cia hlau) ntawm cov vaj tse thaum ub nyob rau hauv cov khoom ntawm xwm thiab tsos.
3.Qhov yog cov xwm txheej uas tsis tshua pom zoo los sis txwv tsis pub muaj cov ntawv thov qub qub?
Qhov chaw pom: Txhua qhov kev nthuav dav uas cuam tshuam rau keeb kwm kev sib tw ntawm lub tsev (xws li cov tsheb ciav hlau, cov khoom siv hniav sib txawv, thiab lwm yam). Nws cov kev xav zoo nkauj tiag tiag undermines keeb kwm huab cua thiab qhabnias.
Hu rau cov khoom siv uas muaj cov muaj txiaj ntsig: kev sib cuag ncaj qha lossis sib thooj nrog cov peev txheej uas muaj peev xwm kho tau xws li tooj liab, tooj liab, nplooj kub. Embedding tseem ceeb keeb kwm cov ntaub ntawv keeb kwm: Cov khoom qhwv cov ntoo tseem ceeb, thiab lwm yam kev puas tsuaj, kev puas tsuaj rau lub cev, thiab thaiv cov khoom ntawm kev ua pa.
Raws li "replica" ntawm tus thawj: sim ua kom rov ua dua cov hlau wrought lossis cam, travertine railings, downspouts) nrog galvanized steel. Cov khoom siv thiab kev ua kom zoo nkauj sib txawv.
4.Qhov dab tsi yog cov xwm txheej nrog kev siv tsawg?
Cov txheej txheem zais ntawm lub zog: ntxiv cov qauv teeb tsa lossis ruaj khov kom pom cov txheej txheem hauv ru tsev Nws yuav tsum yog: ■ zais zais thiab tsis cuam tshuam dab tsi rau cov chaw keeb kwm.
Kev sib cais ntawm lub cev ua tau zoo los ntawm tag nrho cov ntaub ntawv keeb kwm (tshwj xeeb yog ntoo) (xws li siv cov inert inert gaskets, txheej).
Zam kev sib chwv nrog cov meterimilar.
Tsim los xyuas kom ntseeg tau tias yav tom ntej yav tom ntej kom muaj ntau li ntau tau (piv txwv li kev siv bolts tsis siv vuam).
Nws qhov chaw nyob, tshwj xeeb thiab txoj kev teeb tsa tau ua tib zoo sau tseg.
5.What lwm txoj hauv kev?
Cov ntaub ntawv ib txwm muaj: kev xaiv zoo. Siv tib cov ntaub ntawv raws li cov thawj feem ntau li ntau tau (xws li ntoo los ntawm cov qauv ntoo tshwj xeeb, cov hlau wrought wrought, cam khwb cia hlau). Kho es hloov.
Weathering hlau: tiv thaiv lub substrate los ntawm kev tsim lub ruaj khov xeb txheej. Cov xim (xim av liab) yog qhov zoo dua li galvanized steel nyob rau hauv ib puag ncig cov tsev, xav tau kev tsim txiaj thiab kev pheej hmoo ntawm kev tsim kho xeb) yuav tsum tau ua tib zoo saib xyuas. Ntau ntau thaum siv rau kev txhawb nqa. ◦
Stainless hlau: corrosion resistant (tshwj xeeb tshaj yog qib zoo li 316L). Cov xwm txheej tshiab niaj hnub niaj hnub (matte los yog txhuam los yog txhuam tiav), tab sis tsis tshua muaj zog tshaj galvanized steel. Saib xyuas tshwj xeeb yuav tsum tau them rau cov teeb meem corrosion (zam kev sib cuag nrog cov hlau steel, txhuas, zinc). Tus nqi siab.
Titanium alloy: lub zog siab, lub teeb yuag, zoo heev corrosion distance, zoo biocompatibility. Nruab nrab tsos (tawm dawb). Tus nqi siab tshaj plaws. Feem ntau siv rau qhov tseem ceeb, muab zais lossis tsis tshua muaj txiaj ntsig zoo ntawm cov nqi sib txuas.
