1.What cuam tshuam dab tsi tsis zoo txheej txheem zoo muaj ntawm kev tiv thaiv kev ua tau?
Kev nthuav dav ncaj qha ntawm cov xov xwm corrosive: yog tias cov khoom lag luam tsis zoo (cov roj av), thiab cov pa roj av), lossis cov pa tawm hauv av) tuaj yeem nkag mus rau hauv cov txheej av substrate lossis zinc txheej. Lub galvanized txheej nws tus kheej muaj tsawg xeb siv tsis kam (tshwj xeeb tshaj yog thaum zinc txheej yog nyob hauv qab nyias), ua rau oxidation sai). "Pitting" (Nraj Zej Zog) yuav xub tshwm sim, thiab tom qab ntawd corrosion yuav kis mus rau cov chaw ib puag ncig. Tsis pub dhau lub sijhawm luv luv ntawm 3-6 hlis (hauv ib puag ncig huab cua (hauv cov xeb qhuav), muaj ntau xeb yuav tshwm sim, thiab txawm tias lub tais zoo ntawm cov phaj yuav tshwm sim. "Kev sib koom tes ua xeb" exacerbates kev puas tsuaj: yog tias cov txheej poob thaum ua haujlwm lossis siv tsis tau zoo hauv zos), lub substrate ua rau thaj chaw poob qis. Corrosion yuav "nkag mus rau hauv qab ntawm txheej uas tsis tau ua raws li kev sib raug zoo, ua rau muaj kev sib raug zoo, ua rau tag nrho cov rooj sib tham poob nws lub peev xwm tiv thaiv.
2.Yog cuam tshuam dab tsi tsis zoo txheej txheem zoo muaj rau ntawm lub neej pabcuam?
"Lub neej luv luv" hauv kev siv sab nraum zoov: Yog tias siv nyob rau hauv lub ru tsev sab nraum zoov, piv txwv li cov huab cua tsis zoo thiab tsis txaus siab rau cov av noo thiab cua sov) yuav kub ntxhov. Tsis pub dhau 1-2 xyoos, lawv yuav muaj kev sib txawv (xim sib txawv tshaj 3 qib) thiab chalking (pom hmoov uas poob thaum rubbed). Qhov no chates xoob txheej txheej thiab ua rau nws tsis tuaj yeem thaiv cov corrosive kev tshaj tawm, ua rau lub substrate rau xeb. Lub neej pib tsim 10-xyoo yuav muab luv luv mus rau 3-5 xyoos.
"Tshem tawm tsis ua tiav" hauv cov ntawv thov kev lag luam / ntub dej: Thaj chaw noo noo thiab cua sov) yuav ncaj qha corroded los ntawm acid, alkali, thiab ntsev tsuag. Qhov no tuaj yeem ua rau "pitting" (me me corrosion qhov) ntawm txheej txheej sib txawv, lossis txawm qee qhov kev sib cais. Pom rust xeb yuav tshwm nyob rau hauv 3-6 hlis, thaum tsim nyog pleev xim feem ntau kav ntev tshaj 5 xyoos nyob rau hauv xws li ib puag ncig.
3.Qhov kev cuam tshuam dab tsi ua rau cov txheej txheem tsis zoo ua tau zoo muaj kev ua tiav kev ua tau zoo?
Cov txheej txheej thaum lub sijhawm ua: yog tias txheej adhesion tsis zoo (} {{2} {{2} Yuav muaj kev ntxhov siab, tshwj xeeb yog cov kev ntxhov siab, kev ntxhov siab yog nthuav tawm cov kev ntxhov siab Qhov no tuaj yeem ua rau muaj qee yam uas nthuav tawm (ua rau cov txheej zinc txheej lossis substrate) tom qab ua. Qhov no tsis tsuas yog yuav tsum tau ua dua tshiab (ntxiv rau cov txheej txheem), tab sis kuj tseem tuaj yeem ua rau xeb ntawm cov chaw uas muaj cov khoom lag luam. • Txheej tawg thiab pleev xim pleev xim yog qhov tsis sib xws (cov tawv tawv dhau los) lossis tawv heev / tawg yog tshwm sim thaum ua. Cov txheej txheej tuab tuab uas muaj kev ntxhov siab sab hauv thiab sab nraud thaum khoov, ua rau tawg sab hauv. Cov txheej txheem nyuaj ntawm tawv tawv tsis muaj cov txheej txheem thiab muaj peev xwm ncaj qha "thaum muaj cov khoom tsis zoo, ua rau nws tsis muaj peev xwm siv.
4.What yog tus nqi cuam tshuam rau cov khoom tsis zoo?
Kev Kho / Hloov Cov Nqi: Yog tias Pre6-}}}} coated steel siv ua ntej, cov khoom siv qub yuav tsum tau muab tshem tawm thiab hloov nrog cov tshiab. Qhov no tsis tsuas yog ob npaug ntawm cov khoom siv, tab sis kuj tseem ua haujlwm thiab tus nqi tsim kho (tshwj xeeb yog rau cov nqi tsim khoom yog qhov siab dua). Ib qhov project xub pib them 100,000 Yuan tuaj yeem raug ntxiv 50,000 txog 80,000 yuan hauv kev hloov tus nqi tsis pub dhau 3-5 xyoos.
Cov nqi kho vaj tsev theem nrab: yog tias cov txheej txheej zoo nkauj yog cov neeg pluag (piv txwv, kho kom zoo nkauj (xws li kov}, sanding, thiab ua haujlwm) yog qhov tsim nyog. Qhov no yuav tsum tau pleev xim ntxiv thiab ua haujlwm, thiab thaj chaw kho tau zoo rau cov xim sib txawv thiab cov cim sib koom tes, cuam tshuam rau cov loog. Rau cov cuab yeej siv khoom siv, qhov tsis muaj peev xwm kho cov txheej tuaj yeem ua rau cov downgrade ntawm tag nrho cov batch (piv txwv li ntawm "tsis xws luag"), txo qis tus nqi muag.
5.Txoj kev cuam tshuam dab tsi tsis zoo txheej txheem zoo muaj nyob rau ntawm cov ntawv thov?
Cov ntawv thov hniav zoo nkauj yog txwv tsis pub: hauv cov ntawv thov cov vaj tse, kos npe, pinholes, pinholes, lossis xaum ua lub sijhawm luv luv yuav tsis tsim nyog. Piv txwv li, cov xim sib txawv tseem ceeb hauv phab ntsa sab nrauv tuaj yeem cuam tshuam rau lub tsev zoo nkauj tag nrho tuaj yeem cuam tshuam cov khoom siv hluav taws xob. Cov khoom lag luam no tsuas yog siv rau cov kev siv uas pom qhov tseem ceeb tshaj plaws (xws li cov chaw khaws ntaub ntawv noj qab haus huv), muaj feem ntawm tus nqi tsuas yog 50% -70% ntawm tus nqi thawj.
Cov ntawv thov kev pheej hmoo tam sim no muaj kev pheej hmoo siab: hauv kev nyab xeeb} Kev tiv thaiv cov vaj huam sib luag (xws li cov khoom siv tseem ceeb (xws li cov khoom siv tsis zoo tuaj yeem ua rau muaj kev phom sij muaj kev phom sij. Rusted panels poob lub zog, muaj peev xwm ua rau lawv sib tsoo vim tias siv lawv cov kabmob tsis txaus ntseeg yog tias siv rau hauv kev tiv thaiv corrosion thiab zoo nkauj yog tias siv rau kev tiv thaiv khoom siv. Yog li, cov ntawv thov no feem ntau tsis lees txais cov khoom siv tsis lees txais cov khoom tsis zoo, ntxiv txo kev lag luam xav tau.
