1.Dab tsi yog qhov tseem ceeb ua ntej uas yuav tsum tau soj ntsuam ua ntej kev kho dua tshiab?
Qhov zoo tshaj plaws scenario: Cov txheej tsuas yog qhia qhov chaw chalking thiab fading, tab sis lub hauv paus hlau (zinc plating / aluminized zinc plating) tsis raug thiab xeb -dawb. Qhov no yog lub hom phiaj zoo tshaj plaws rau kev kho dua tshiab, muab cov txiaj ntsig zoo tshaj plaws.
Cov xwm txheej kho tau: Cov kab xeb hauv cheeb tsam lossis cov stains, tab sis cov hlau hauv paus tsis nkag los ntawm xeb (piv txwv li, tsis muaj qhov hollow thaum tapping, xeb tuaj yeem ua kom huv si). Yuav kom tshem tawm xeb ntxiv thiab kho cov kauj ruam.
Unreplaceable scenario: Lub hauv paus hlau tau ntau corroded thiab perforated, los yog xeb tau pib los ntawm sab nraum qab. Hauv qhov no, lub zog ntawm cov txheej txheem raug cuam tshuam, kev kho dua tshiab yog qhov tsis muaj txiaj ntsig, thiab kev hloov pauv yog tsim nyog.
Kev huv ntawm qhov chaw: Tshawb xyuas cov roj, tshuaj lom neeg, plua plav ntau dhau, lossis algae. Cov no yuav tsum tau muab tshem tawm kom huv si ua ntej thov.
2.Qhov txheej txheem kho dua tshiab yog dab tsi?
Kauj Ruam 1: Kev Tshawb Fawb thiab Kev Ntsuam Xyuas
Tshawb xyuas qhov cuam tshuam ntawm substrate corrosion, txheej adhesion, thiab kev ruaj ntseg ntawm qhov uas twb muaj lawm mounting system.
Txiav txim siab txog kev kho dua tshiab thiab cov khoom siv.
Kauj Ruam 2: Kev Kho Ntog (Cov kauj ruam tseem ceeb tshaj plaws, suav txog ntau dua 50% ntawm cov haujlwm ua haujlwm)
High -Kev ntxuav dej siab: Tshem tawm cov plua plav, cov khoom xoob, thiab cov hmoov txheej txheej qub.
Kev xuab zeb hauv zos / Zuag qhia tag nrho: Rau thaj chaw corroded, siv cov cuab yeej hluav taws xob los xuab zeb kom txog thaum cov khoom siv tau raug nthuav tawm (St2-St3 standard).
Zuag qhia tag nrho roughening: Rau qhov chaw uas siv tau tab sis du txheej qub adhesion, ua tag nrho lub teeb roughening kom cov adhesion ntawm cov txheej tshiab.
Kev tu ntxiv: Yaug nrog siab - cua siab lossis dej kom ntseeg tau tias qhov chaw tsis muaj qhov seem thiab qhuav tag.
Kauj Ruam 3: Kho thiab Primer
Kev Kho Hniav: Tam sim ntawd siv ib qho tshwj xeeb "epoxy zinc-nplua nuj primer" los yog "rust converter" mus rau qhov chaw raug hlau tom qab xuab zeb rau ib tug neeg tiv thaiv corrosion.
Zuag qhia tag nrho Primer: Siv ib lub tsho tiv no tshwj xeeb kho dua tshiab primer sib xws nrog ob qho tib si qub thiab tshiab txheej. Nws ua raws li cov txheej txheem qub thiab muab lub hauv paus zoo rau topcoat.
Kauj ruam 4: Topcoat
Siv 1-2 lub tsho loj ntawm siab- zoo "specific topcoat," xws li acrylic polyurethane lossis fluorocarbon topcoat. Xim tuaj yeem xaiv raws li xav tau.
Cov Lus Cim Tshwj Xeeb: Qhov yooj yim ntawm cov tsho tiv no tshiab yuav tsum ua kom haum rau thermal expansion thiab contraction ntawm cov hlau vov tsev panels; txwv tsis pub, cracking yog yuav.
3.Dab tsi yog qhov tseem ceeb ceev faj thiab txaus ntshai?
Compatibility Risks: Cov txheej txheem tshuaj ntawm cov txheej txheem tshiab thiab qub yuav tsis sib haum, ua rau wrinkling thiab tev. Cov me me -thaj chaw sim lossis kev sab laj nrog tus neeg muab xim yog tsim nyog.
Adhesion yog qhov tseem ceeb: Tsis txaus adhesion yog thawj qhov ua rau cov txheej txheem tshiab tsis ua haujlwm. Txawm tias cov xim zoo tshaj plaws yuav tev tawm yog tias qhov kev npaj saum npoo tsis txaus.
Warranty Issues: Lub sij hawm lav rau kev kho dua tshiab (feem ntau yog 1-5 xyoos) luv dua li kev tsim kho tshiab, thiab muaj ntau qhov tsis lees paub txog qhov tseem ceeb ntawm lub substrate.
Kev xaiv tus neeg cog lus: Ib txwm xaiv ib pab neeg tsim kho uas muaj kev paub dhau los hauv loj - nplai kev lag luam los tiv thaiv- corrosion lossis corrugated steel ntawv kho dua tshiab, tsis yog cov neeg pleev xim tsev zoo tib yam.
Kev nyab xeeb thiab kev tiv thaiv ib puag ncig: Cov txheej qub qub yuav muaj cov hlau hnyav xws li txhuas (hauv cov tsev laus). Kev tswj plua plav thiab kev tiv thaiv yog tsim nyog thaum xuab zeb.
4.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev thov ncaj qha rau cov xim kho dua tshiab?
Qhov zoo: Tus nqi qis dua, daim ntawv thov ceev heev.
Qhov tsis zoo: Yuav tsum muaj siab - cov txheej qub qub, lub neej luv luv (5-8 xyoo).
5.Dab tsi yog qee qhov lus pom zoo rau kev txiav txim siab- txheej txheem?
Tshawb xyuas lub substrate: Yog hais tias muaj ntau xeb nkag, npaj rau kev hloov.
Ntsuam xyuas koj cov peev nyiaj thiab kev cia siab: Yog tias koj cov peev nyiaj tsawg thiab cov khoom siv hauv qab tau zoo, kev kho dua tshiab yog qhov kev xaiv zoo dua. Yog tias koj ua qhov tseem ceeb tshaj plaws lifespan thiab xoom txij nkawm, thiab muaj peev xwm, hloov tag nrho cov substrate yog yooj yim dua.
Ntiav kev ntsuam xyuas kev tshaj lij: Ua ntej txiav txim siab, muaj lub tuam txhab kev tiv thaiv kev tiv thaiv corrosion los yog cov khoom siv txheej txheej ua rau ntawm - kev tshuaj xyuas qhov chaw thiab muab cov phiaj xwm sau thiab cov lus hais.
