Vim tias nws tau du, nplua nto thiab yog zinc/zinc txheej, galvanized hlau tuaj yeem nyuaj rau pleev xim. Ua ntej pib, cov hlau saum npoo yuav tsum tau npaj kom cov xim tuaj yeem ua raws. Pib los ntawm kev ntxuav tag nrho cov hlau nrog tshuaj degreaser. Thaum ua tiav, so sab nrauv nrog cov kua txiv hmab txiv ntoo kom maj mam kos rau saum npoo thiab ua kom yooj yim dua rau cov xim kom ua raws; kuj tseem nco ntsoov tias koj txhuam cov hlau ntawm cov hlau nrog cov ntawv txhuam kom tshem tawm cov seem uas muaj oxidized zinc (tseem hu ua "dawb xeb"). Thaum kawg thov siv cov tshuaj pleev xim sab nraum zoov rau cov hlau, tom qab ntawd ua tiav nrog ob lub tsho loj ntawm cov xim pleev xim sab nrauv.
Kauj ruam
Ntu 1 ntawm 2: Npaj Cov Hlau Hlau
Kauj Ruam 1. Ntxuav cov hlau nrog tshuaj degreaser
Txau qhov saum npoo nrog cov tshuaj, tom qab ntawd txhuam nrog daim ntaub huv, tsis muaj lint. Lub tshuab degreaser muaj zog yuav nkag mus rau hauv av, roj, pwm thiab lwm yam teeb meem seem uas tsis cuam tshuam rau qhov kub txheej zinc txheej. Txuas ntxiv hauv ntu me me kom txog thaum txhua qhov chaw hlau huv.
- Cov khoom siv hauv tsev zoo ib yam xws li cov ntxhia ntxhia thiab tshuaj chlorine tuaj yeem siv los npaj cov hlau galvanized.
- Yog tias koj tab tom sim pleev xim rau sab phab ntsa, lub teeb ci ntsa iab, lossis lwm yam khoom raug rau lub ntsiab, ua kom huv si kom tshem tawm cov kab mob tsis huv los ntawm cov hlau sab nrauv.
Kauj Ruam 2. Tso cov hlau saum npoo kom qhuav
Yog tias cov hlau tau raug ntxuav, tos kom txog thaum tag nrho cov kab ntawm cov degreaser tau evaporated. Txoj kev no, tus degreaser yuav tsis cuam tshuam nrog kev ua haujlwm ntawm cov kua txiv hmab txiv ntoo, uas yuav siv los ua kom cov hlau tsis huv.
Yog tias ua tau, kev npaj thiab tha xim ntawm cov hlau yuav tsum tau nqa tawm thaum tshav ntuj, tsis ntub
Kauj Ruam 3. Rub cov hlau galvanized maj mam tshem cov xeb dawb
Rau cov khoom hnav, feem ntau muaj txheej txheej ntawm chalk lossis hmoov rau ntawm qhov chaw. Cov txheej no tuaj yeem tshem tawm tau yooj yim siv cov ntawv loj (ntxhib) cov ntawv xuab zeb (nyiam dua 120 pob zeb) thiab ua siab ntev me ntsis. Rub cov hlau nyob rau hauv cov lus tsa suab kom txog thaum lub ntsej muag zoo ib yam.
- Tom qab ntawd, so lub ntsej muag nrog daim ntaub dampened hauv dej sov kom tshem tawm cov hmoov av.
- Cov kua qaub no hu ua dawb xeb. Cov xeb no tshwm sim thaum cov txheej zinc ntawm cov hlau pib tawg vim lub hnub nyoog lossis raug rau ntau yam.
Kauj Ruam 4. So cov hlau nrog cov kua dawb
Ntub daim ntaub huv, qhuav nrog cov kua txiv hmab txiv ntoo dawb dawb thiab rub tawm kom txog thaum nws tsis los kua. So cov hlau galvanized kom huv, thiab ntxiv kua txiv yog tias xav tau. Txhawm rau pleev xim kom ua haujlwm tusyees, kua txiv hmab txiv ntoo yuav tsum kov txhua feem ntawm sab nrauv.
- Cov kua qaub hauv cov kua txiv hmab txiv yuav ua rau txheej txheej txheej zinc, ua rau nws ntxhib ntxhib thiab zoo dua rau cov xim.
- Yog tias koj plam qee qhov, cov xim yuav ua rau tawg lossis tev tawm.
Kauj Ruam 5. Tawm lub kua txiv rau 1-2 teev
Lub sijhawm no tso cai rau cov kua qaub kom noj cov nplaim galvanizing. Ntev nws nyob ntawm qhov ntev dua, qhov ua tau zoo tshaj qhov cuam tshuam ntawm kev kos, thiab cov xim yuav ua tau zoo dua. Yog ua tau, cia nws zaum ib hmos.
Yog tias tsis muaj sijhawm txaus, tos kom qhov saum npoo av qhuav thiab kov tau ua ntej txav mus rau txheej txheej thiab txheej xim
Ntu 2 ntawm 2: Thov Primer thiab Xim
Kauj Ruam 1. Thov siv cov tshuaj pleev xim raws cov yas
So los yog tshuaj tsuag tus primer mus rau cov hlau npaj. Ua haujlwm hauv ntu me me kom cov txiaj ntsig zoo ib yam. Nco ntsoov tias tsis muaj cov seem uas ploj lawm lossis nyias nyias uas tuaj yeem tsim teeb meem tom qab.
- Txog qhov ua tau ntev tshaj plaws thiab ua kom khov, xaiv ntau yam tshuaj yaj yeeb ua ntej tsim rau sab nraum zoov.
- Yog tias cov hlau tau tsim rau kev lag luam hnyav lossis sab nraum zoov, nws yog qhov zoo tshaj los xaiv cov epoxy primer uas zoo dua. Epoxy primers muab cov nplaum ib ntus, thiab tiv taus khawb, nicks, thiab tev tawm.
Kauj Ruam 2. Tso tus primer kom qhuav tag
Feem ntau nws yuav siv sijhawm li 2-6 teev, nyob ntawm qhov khoom siv. Txhawm rau kuaj seb puas muaj cov xim pleev xim, so koj cov ntiv tes. Yog tias nws tseem hnov nplaum, koj yuav tsum tau tos ntev me ntsis.
Yog tias koj pleev xim rau ntawm cov dej ntub dej ntub, cov nplaum yuav txo qis
Kauj Ruam 3. Xaiv cov xim kom raug
Feem ntau, cov xim txheej txheem tsim rau sab nraum zoov yuav txaus. Koj tuaj yeem yuav nws ntawm lub khw pleev xim lossis kho vajtse. Zam kev siv cov xim alkyd (piv txwv li tshuaj tsuag xim) ntawm cov hlau galvanized.
- Rau qhov ua tau zoo tshaj plaws, saib cov xim tshwj xeeb uas tsim los rau galvanizing hlau.
- Cov xim pleev xim hauv cov xim alkyd tuaj yeem cuam tshuam nrog txheej txheej zinc ntawm saum npoo ntawm cov hlau galvanizing, ua rau cov xim tsis ua zoo thiab tev.
Kauj Ruam 4. So thawj lub tsho xim
Thov pleev xim rau tag nrho cov hlau saum npoo ntev, ncaj ncaj. Siv qhov txhuam ntawm qhov txhuam kom mus txog qhov nqes hav, qhov, thiab thaj chaw. Txheeb xyuas kom paub tseeb tias tsis muaj qhov khoob lossis qhov seem tshuav tom qab ua ntej mus.
Koj tuaj yeem siv cov menyuam los pleev xim rau qhov chaw loj xws li cov vaj huam sib luag sab lossis lub ru tsev
Kauj Ruam 5. Tso lub hauv paus tsho kom qhuav thiab kov
Feem ntau nws yuav siv sijhawm 3-4 teev ua ntej lub tsho thib ob tuaj yeem pleev xim. Lub caij no, tsis txhob kov cov xim ntub kom tsis txhob tawm ntawm cov kab los yog qhov ua paug ntawm cov khoom tiav.
Cia siab tias ntev dua cov xim qhuav hauv qhov sov, huab cua sov
Kauj Ruam 6. Txuas ntxiv nrog lub tsho xim thib ob thiab zaum kawg
Ob txheej yog feem ntau txaus rau feem ntau cov haujlwm. Thov pleev xim tom ntej zoo li thawj lub tsho loj. Siv sijhawm los xyuas kom tsis muaj qhov tsis xws luag hauv koj txoj haujlwm; txhua qhov yuam kev yuav tshwm sim thaum cov xim qhuav.
- Cov cua tsis zoo los ntawm cov kiv cua lossis cov tshuab cua tuaj yeem pab pleev xim kom qhuav sai dua.
- Yog tias txheej txheej xim tau qhuav, thov txhim kho lossis tso cov hlau raws li nws siv.
Kauj Ruam 7. Txwv cov xim thaum nws tawv
Txawm hais tias feem ntau cov xim pleev xim qhuav hauv ob peb teev, nws tuaj yeem siv sijhawm ntau lub lis piam (lossis qee zaum txog li ib hlis) kom tawv tawv. Yog tias ua tau, tiv thaiv cov hlau los ntawm kev ntxhov siab thiab hnav, xws li los ntawm kev nyuaj siab, nag lossis daus hnyav, lossis hloov pauv kub kom txog thaum cov xim tau tawv tag nrho. Thaum nws nyuaj, cov xim tuaj yeem tiv taus txhua yam uas tsoo nws.
Yog tias siv kom raug, pleev xim rau ntawm cov hlau galvanized yuav kav ntev thiab tiv taus cov xwm txheej hnyav
Lub tswv yim
- Hnav cov hnab looj tes pov tseg kom tiv thaiv txhais tes kom tsis txhob raug cov tshuaj ntxhua khaub ncaws thiab xim pleev xim thaum ua haujlwm.
- Kev pleev xim rau xim hlau yog qhov haujlwm sai thiab pheej yig uas txhua tus tuaj yeem ua tau; Koj tsuas yog xav tau xim thiab primer, thiab ob peb teev, feem ntau tos rau xim lossis primer kom qhuav.
- Galvanized hlau nto qee zaum kho nrog cov tshuaj hu ua passivators, uas tiv thaiv sab nrauv los ntawm kev xeb tab sis tuaj yeem cuam tshuam cov xim tha xim. Txhawm rau kuaj pom tias muaj tus neeg hla dhau, xuab zeb cov hlau nyob hauv thaj chaw uas tsis pom thiab rub nws nrog tooj liab sulfate diluted nrog dej. Yog tias ob qhov tsaus ntuj ntawm qhov sib txawv sib txawv, nws yuav zoo li qhov passivation tau thov rau cov hlau, thiab tsis tuaj yeem pleev xim kom txog thaum tshwj xeeb huab cua tau thov.
