Q1: Thaum twg yuav tsum tau kho dua tshiab? Puas muaj tej yam kev txiav txim?
Tsis muaj lub sijhawm teem sijhawm rau kev kho dua tshiab; tus yuam sij yog saib xyuas "kev noj qab haus huv cov cim" ntawm cov laug cam. Nws feem ntau pom zoo kom muaj kev tshuaj ntsuam xyuas txhua 5-10 xyoo, thiab txiav txim siab hloov pauv raws li qhov tshwj xeeb.
"Cov cim ceeb toom" yuav tsum tau kho tam sim ntawd feem ntau suav nrog ob lub ntsiab lus:
Txheej tsis ua hauj lwm: Loj- thaj tsam hmoov (hmoov tawm thaum kov), blistering, tawg, discoloration ntau tshaj 30%, los yog xeb me ntsis tshwm ntawm cov ntsia hlau qhov los yog txiav ntug.
Kev phom sij ntawm cov qauv: Localized deformation los yog loosening ntawm cov laug cam, los yog pom tseeb cov cim ntawm dej to.
Q2: Vim li cas qhov kev kho saum npoo thiab xuab zeb yog thawj kauj ruam tseem ceeb ua ntej kev kho dua tshiab?
90% ntawm renovation tsis ua hauj lwm tshwm sim los ntawm qhov chaw kho mob theem. Ntau tus neeg ntseeg tias qhov du, huv si ntawm daim ntawv qub muaj kev nyab xeeb rau xim ncaj qha, tab sis qhov no yog qhov txaus ntshai tshaj plaws zais cia ua rau tev thiab flaking ntawm cov xim zaj duab xis.
Cov zinc nyob rau saum npoo ntawm cov ntawv galvanized yog chemically reactive. Yog tias tsis sanded, nws cov oxidation thiab kev tsiv teb tsaws yuav ncaj qha "tawg" cov xim tshiab. Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tau ua "roughening" kev kho mob los ntawm mechanical sanding. Qhov no tsis yog tsuas yog rhuav tshem cov txheej txheej galvanized overly du, ua rau lub cev roughness, tab sis kuj txo nws cov reactivity, muab lub zog "suav" rau cov txheej tom ntej. Ib txhij, xuab zeb yuav tsum tau muab tshem tawm cov xim qub qub kom txog thaum cov ntawv galvanized tshiab tau nthuav tawm. Tom qab ntawd, tag nrho cov plua plav, roj, thiab cov khib nyiab hlau yuav tsum tau muab ntxuav.
Q3: Yuav ua li cas xaiv cov xim kho kom zoo rau cov xim galvanized-coated steel ntawv?
Xaiv cov xim tsis raug tuaj yeem ua rau tag nrho koj qhov kev siv zog tsis muaj txiaj ntsig. Tsis txhob siv cov xim pleev xim rau phab ntsa. Ua ntej dej-raws li, cov xim zoo nkauj ib puag ncig tshwj xeeb tsim rau hlau; lawv yog cov phooj ywg ib puag ncig, muaj cov ntsiab lus VOC tsawg, thiab muaj zog adhesion rau txheej galvanized.
Q4: Dab tsi yog cov ntsiab lus tseem ceeb thiab ceev faj thaum tsim kho?
Kev tsim kho zoo ncaj qha txiav txim siab qhov kev kho dua tshiab thiab kev ua neej nyob. Nov yog qee cov ntsiab lus tseem ceeb ntawm kev ua haujlwm:
Kev xaiv ib puag ncig: Qhov zoo tshaj plaws, huab cua av noo yuav tsum tau tswj ntawm 30% thiab 50% thaum tsim kho. Zam kev tsim kho rau hnub los nag, nyob rau hauv tshav ntuj ncaj qha, lossis hauv qhov kub qis dua 5 degree.
Kev sib xyaw thiab Thickness: nruj me ntsis tswj cov xim viscosity raws li cov lus qhia khoom. Ib txheej txheej dhau lawm yuav ua rau lub zog zais tsis zoo, thaum tuab tuab heev yuav ua rau sagging. Nws raug nquahu kom tswj tag nrho cov yeeb yaj kiab qhuav tuab rau 60-80μm (kwv yees li 2-3 lub tsho tiv no).
Daim Ntawv Thov Txheej: Nws raug nquahu kom tso cai rau 2-4 teev ntawm kev siv cov primer thiab topcoat kom ntseeg tau tias lub tsho tiv no dhau los qhuav tag.
Kev sib khi ntawm cov pob qij txha: Re- foob tag nrho cov ntsia hlau qhov, sib tshooj, eaves, ridges, thiab lwm yam tseem ceeb pob qij txha nrog ib tug nruab nrab, huab cua- resistant sealant (xws li silicone sealant). Qhov no yog ib kauj ruam tseem ceeb hauv kev tiv thaiv cov xau.
Q5: Cov nqi kwv yees thiab nqi yog dab tsi -kev ua tau zoo ntawm kev kho dua tshiab?
Kev kho dua tshiab muaj txiaj ntsig zoo dua rau cov nyiaj piv rau kev hloov ua tiav. Nyob rau hauv cov nqe lus ntawm kev ua lag luam tus nqi, ib qho yooj yim xim kho dua tshiab (nrog rau kev ua hauj lwm thiab cov ntaub ntawv) nqi kwv yees li 8-20 RMB ib square meter. Yog tias yuav tsum tau kho ib nrab ntxiv nrog rau kev kho kom tiav, tus nqi ntau yog feem ntau 150-200 RMB ib square meter. Hauv qhov sib piv, kev hloov ua tiav (nrog rau cov vaj huam sib luag tshiab, rwb thaiv tsev, thiab kev ua haujlwm) yog kim dua, raug nqi kwv yees li 300-400 RMB ib square meter.
Kev xaiv kho dua tshiab tsis yog tsuas yog txo cov nqi xwb tab sis kuj ua rau tus nqi ntau tshaj -kev ua tau zoo. Lub tshuab kho dua tshiab tuaj yeem daws cov teeb meem corrosion zoo, tso cai rau lub ru tsev txuas ntxiv siv yam xyuam xim rau ntau tshaj 10 xyoo. Nws raug nquahu kom siv lub tswv yim "kho cov teeb meem me me thaum ntxov", qhia tam sim thiab daws cov teeb meem me me kom txo tau tag nrho cov nqi kho mob ntev -.
