Q: Lub neej kwv yees li cas ntawm cov xim galvanized-coated steel coils yog dab tsi?
A: Lub neej ntev sib txawv heev nyob ntawm cov khoom zoo thiab kev siv ib puag ncig, feem ntau yog li ntawm 7 txog 35 xyoo.
Cov lus hauv qab no tuaj yeem pab koj nkag siab sai sai ntawm qhov sib txawv ntawm lub neej:
Lifespan Qib|Yam xwm txheej|Kev ua neej nyob
Nkag mus -level|Ordinary factories, warehouses, thiab lwm lub tsev nyob rau hauv ib puag ncig zoo|7-10 xyoo
Siab- qib kev ua tau zoo|Cov vaj tse uas yuav tsum tau ua kom ntev, xws li cov uas siv PVDF txheej|Ntau tshaj 20 xyoo
Theoretical txwv|Tej yam tshwj xeeb siab- cov khoom ua tau zoo, xws li cov ntawv aluminized zinc (lifespan ntau dua 4 npaug ntawm cov ntawv zoo tib yam galvanized)|22-35 xyoo
Q: Yuav ua li cas cov ntaub ntawv raw lawv tus kheej txiav txim siab cov khoom lifespan?
A: Qhov zoo ntawm cov khoom siv raw, tshwj xeeb tshaj yog kev xaiv ntawm substrate thiab txheej, yog qhov tseem ceeb ntawm kev txiav txim siab cov khoom "inherent lifespan." Ntawm cov no, cov khoom siv txheej thiab thickness ntawm substrate yog thawj kab ntawm kev tiv thaiv.
Lub substrate yog qhov tseem ceeb: Kev tiv thaiv corrosion ntawm lub substrate yog qhov tseem ceeb.
Cov khoom siv txheej txheej: Kev tiv thaiv corrosion ntawm aluminized zinc-coated steel nplooj ntawv feem ntau yog ntau tshaj plaub npaug ntawm cov nplooj ntawv galvanized zoo tib yam, uas ua rau lub neej ua haujlwm ntev dua.
Txheej thickness: Lub thicker txheej, lub neej ntev. Cov txheej txheej hnyav muaj xws li Z120, Z180, thiab Z275, nrog Z275 muab kev tiv thaiv corrosion zoo dua li Z120.
Cutting corrosion: Lub thinner lub substrate thiab txheej, qhov cuam tshuam ntau dua ntawm cov npoo ntawm daim ntawv yog electrochemical corrosion, ua thawj qhov tsis muaj zog.
Txheej yog ib qho kev thaiv: Dhau li ntawm kev zoo nkauj, txheej txheej tseem ceeb tshaj plaws yog los tiv thaiv lub substrate.
Txheej hom: Los ntawm PE thiab SMP rau HDP thiab PVDF, lawv cov huab cua tsis kam, UV tsis kam, thiab tshuaj lom neeg corrosion kuj nce nyob rau hauv qhov kev txiav txim, nrog rau cov nqi siab dua thiab sib txawv lifespans.
Q: Qhov chaw sab nraud cuam tshuam li cas rau lub neej?
A: Lub corrosiveness ntawm ib puag ncig yog qhov tseem ceeb tshaj plaws sab nraud uas txiav txim siab txog kev ua neej.
Cov chaw lag luam thiab thaj chaw ntug dej hiav txwv: Cov pa roj carbon ntau ntawm cov kua qaub xws li sulfur dioxide thiab ntsev hauv huab cua nrawm nrawm thiab ua rau lub neej luv luv.
Humidity thiab condensation: Cov cheeb tsam raug los nag los yog muaj kev sib xyaw ua ke vim qhov kub ntawm diurnal loj hloov pauv sai dua.
Muaj zog ultraviolet hluav taws xob: Kev raug tshav ntuj ntev ntev tuaj yeem ua rau cov txheej txheem muaj hnub nyoog, poob lawv cov ci, chalk, thiab txawm tawg, ua rau tsis ua haujlwm.
Biological corrosion: Hauv qee qhov chaw, xws li hav zoov hav zoov hav zoov, qhov yaig los ntawm pwm thiab lwm yam kab mob tuaj yeem ua kom cov txheej txheej laus.
Kev qias neeg qias neeg: Cov plua plav nqus nqus cov dej noo thiab cov khoom corrosive, accelerating localized corrosion. Yog li ntawd, thaj chaw uas nquag ntxuav los ntawm nag yog qhov ua tau ntev dua.
Q: Dab tsi yog qee qhov kev txiav txim siab tseem ceeb thaum tsim thiab tsim kho?
A: Kev ua haujlwm tsis raug thiab kev teeb tsa ncaj qha tuaj yeem ua rau lub neej luv luv.
** Kev Tiv Thaiv Txiav thiab khawb: ** Txiav lossis qhib qhov tsim los ntawm kev txiav yog cov ntsiab lus tsis muaj zog hauv kev tiv thaiv corrosion. Tag nrho cov npoo txiav yuav tsum tau muab kaw kom zoo los tiv thaiv electrochemical corrosion. Tsis txhob khawb cov txheej nrog cov khoom ntse thaum thauj thiab teeb tsa.
** Kev xaiv cov khoom siv txuas:** Siv cov hlau tsis muaj steel lossis tshwj xeeb coated fasteners uas muaj peev xwm zoo sib xws los yog tsis ua rau electrochemical corrosion ntawm cov xim -coated steel ntawv.
**Kev nqes hav thiab dej ntws:** Kev txhim kho lub ru tsev txoj kab nqes thaum lub sij hawm tsim ua kom yooj yim rau cov kua dej thiab tus kheej- ntxuav, txo cov kab mob adhesion, thiab yog li ncua lub neej.
** Zam Kev Tiv Thaiv Cov Txuas Hluav Taws Xob: ** Txhim kho thermal rwb thaiv tsev pads ntawm cov pob qij txha xws li cov joists tuaj yeem tiv thaiv kev sib xyaw ua ke hauv cov qauv vim qhov kub sib txawv, yog li tiv thaiv kev xeb sab hauv.
Q: Yuav ua li cas tshaj tawm - kev txhim kho kev tsim kho kom ntev lub neej ntawm qhov system?
A: Kev tu thiab tu tsis tu ncua yog txoj hauv kev yooj yim tshaj plaws thiab muaj txiaj ntsig zoo tshaj plaws rau kev ua neej ntev.
Kev Tu Kom Zoo: Nws raug nquahu kom yaug qhov chaw nrog dej huv txhua 1-2 xyoos kom tshem tawm cov plua plav, cov noog poob, thiab lwm yam corrosive deposits. Cov cheeb tsam uas tsis tshua raug los nag yuav tsum tau ntxuav ntau zaus.
Kho raws sij hawm: Yog tias khawb, xeb, lossis xeb ntawm qhov txiav raug pom, tam sim ntawd ua cov xuab zeb hauv zos, tshem tawm xeb, thiab siv qhov sib txuam - cov xim pleev xim kom tsis txhob xeb los ntawm kev sib kis.
Tshuaj xyuas cov pob qij txha: tsis tu ncua xyuas cov pob qij txha, cov ntsia hlau, thiab lwm yam kev sib txuas kom ntseeg tau tias lub sealant tsis zoo thiab tiv thaiv cov dej tawm.
