Yog tias koj tau saib lub laj kab uas muaj cov saw hlau txuas, ib daim ductwork kev lag luam, lossis cov kav dej xim nyiaj-grey hauv qab nthab qub, koj tau pom cov hlau galvanized. Nws yog ib yam khoom siv ua haujlwm, tab sis nws feem ntau nkag siab yuam kev. Cov neeg feem coob kho nws zoo li hlau tsis xeb lossis hlau nyoos, tab sis qhov ntawd yog qhov yuam kev uas tuaj yeem ua rau muaj xeb hauv ob peb lub hlis xwb.
Qhov zais cia ntawm cov hlau galvanized yog zinc. Yuav kom ua tau cov hlau galvanized, cov chaw tsim khoom muab cov hlau tso rau hauv lub dab dej uas yaj ntawm zinc. Qhov no tsim ib txheej "txhiv dim".kev pleev xim galvanizing—txhais tau tias cov zinc yuav xeb thiab raug kev cuam tshuam los ntawm ib puag ncig yog li cov hlau hauv qab tsis tas yuav xeb. Thaum koj ntxuav nws, koj txoj haujlwm tseem ceeb yog khaws cov txheej zinc ntawd kom zoo. Yog tias koj txhuam nws tawm lossis yaj nws nrog cov tshuaj tsis raug, koj tsuas yog tig koj cov hlau ruaj khov mus ua ib daim seem uas tos kom xeb.
Nov yog kev kawm tob txog txoj hauv kev zoo los siv cov khoom no, txawm tias koj tab tom txhuam ib daim khoom dai kom zoo nkauj lossis tswj cov kav dej.
Txoj Kev Qhia Txheem: Ua Kom Yooj Yim
Rau feem ntau ntawm cov haujlwm ntxuav, koj yeej tsis xav tau cov tshuaj lom neeg hauv kev lag luam zoo nkauj. Qhov tseeb, txoj hauv kev "zoo tshaj plaws" los ntxuav cov hlau galvanized feem ntau yog qhov yooj yim tshaj plaws. Yog tias koj tsuas yog cuam tshuam nrog cov hmoov av, av qias neeg, lossis av nkos txhua hnub, ua raws li cov hauv paus.
Koj yuav tsum tau dab tsi:
Dej sov
Ib xab npum ntxuav tais diav uas tsis muaj pH ntau
Ib txhuam mos mos uas muaj cov nylon bristles (tsis txhob siv cov txhuam uas muaj cov hlau bristles)
Ib daim ntaub microfiber
Pib los ntawm kev ntxuav qhov chaw nrog dej dawb kom tshem tawm cov khib nyiab xoob. Tom qab ntawd, sib tov me ntsis xab npum rau hauv ib lub thoob dej sov thiab mus ua haujlwm nrog txhuam nylon. Txhuam hauv kev txav mus los, tsom mus rau thaj chaw uas muaj av qias neeg. Qhov laj thawj peb siv nylon yog vim nws tawv txaus los tshem cov av tab sis mos txaus kom nws yuav tsis tawm qhov khawb me me hauv cov txheej zinc. Thaum koj ua tiav, yaug nws kom huv si.
Txoj Cai Kub:Yog tias muaj dej ntws rau ntawm cov hlau galvanized ces tsis txhob cia nws qhuav. Dej sawv yog tus yeeb ncuab. Siv ib daim phuam huv thiab so nws tam sim ntawd. Yog tias koj tsis ua li ntawd, koj yuav pom "xeb dawb" (zinc hydroxide) tsim nyob rau hauv 24 teev.
Kev daws teeb meem roj, roj, thiab nplaum
Qee zaum, xab npum thiab dej yuav tsis ua haujlwm - tshwj xeeb tshaj yog tias koj tab tom ntxuav cov kav dej galvanized uas tau nyob hauv chav nres tsheb lossis chaw ua haujlwm. Tej zaum koj yuav pom cov roj tuab lossis cov khoom nplaum los ntawm daim kab xev qub.
Hauv qhov no, tsis txhob siv cov tshuaj txhuam thiab nrhiav cov tshuaj yaj. Cov tshuaj ntxhia lossis tshuaj tsuag WD-40 sai sai ua haujlwm zoo kawg nkaus ntawm no. Muab cov tshuaj yaj rau ntawm daim ntaub mos mos, tsis txhob ncaj qha rau ntawm cov hlau, thiab txhuam qhov chaw uas raug mob. Siv cov tshuaj ntxhia, tom qab ntawd ntxuav nrog cov tshuaj ntxuav mos mos kom tshem tawm cov tshuaj yaj seem. Qhov no yaj cov organic compounds hauv cov roj yam tsis cuam tshuam nrog zinc. Thaum cov roj ploj mus, nco ntsoov so qhov chaw nrog daim ntaub ntub dej kom tshem tawm cov tshuaj yaj seem, tom qab ntawd ziab nws.
Kev Saib Xyuas Tshwj Xeeb rauCov Kav Dej Galvanized
Kev ntxuav cov yeeb nkab galvanized yog ib qho txawv me ntsis. Yog tias koj tab tom cuam tshuam nrog sab nraud ntawm cov yeeb nkab - tej zaum vim koj xav pleev xim rau nws - koj yuav tsum "etch" qhov chaw. Cov hlau galvanized tshiab muaj ib txheej nplaum heev, roj (feem ntau yog txheej passivate) uas ua rau cov xim tev tawm tam sim ntawd.
Txhawm rau ntxuav thiab npaj sab nraud ntawm lub yeeb nkab rau kev pleev xim, ntau tus kws tshaj lij siv cov kua txiv qaub dawb.Tab sis vinegar tsuas yog rau cov khoom me me DIY xwb. Yog tias koj yog qhov project industrial zoo tshaj plaws sivCov tshuaj ntxuav zinc tshwj xeeb / T-ntxuav.Cov acetic acid me me hauv vinegar pab tshem tawm qhov slickness thiab me ntsis roughness cov zinc kom cov xim tuaj yeem tuav tau.
Yog koj tso cov kua txiv qaub (lossis lwm yam kua qaub) rau ntawm cov yeeb nkab ntev dhau, nws yuav pib noj cov zinc. Koj yuav paub tias qhov kev ua haujlwm tshwm sim vim tias cov hlau yuav pib ua npuas thiab tso cov pa hydrogen tawm. Siv nws tsawg tsawg!
Rau qhovsab hauv ntawm cov kav dej galvanized, tej yam nyuaj dua. Yog tias koj lub zog dej qis vim muaj cov ntxhia hauv cov yeeb nkab, kev ntxuav nws tsis yog qhov kho tau tas mus li. Vim tias sab hauv raug dej tas li, cov zinc thaum kawg hnav tawm, thiab cov txheej txheem "ntxuav" feem ntau tsuas yog qhia txog xeb hauv qab. Feem ntau, yog tias cov yeeb nkab galvanized raug txhaws sab hauv, nws yog ib qho cim qhia tias cov yeeb nkab tab tom mus txog qhov kawg ntawm nws lub neej.
Yuav kho li cas "Xeb Dawb" thiab "Xeb Liab"
Yog tias koj tso koj cov hlau galvanized tseg rau hauv nag lossis khaws cia rau hauv lub tsev me me uas ntub dej, koj yuav pom cov hmoov dawb, zoo li chalky rau ntawm qhov chaw. Qhov no yogxeb dawbNws tsis yog xeb "tiag tiag" (uas yog hlau oxide), tab sis nws yog ib qho cim qhia tias cov zinc ua haujlwm dhau sijhawm los tiv thaiv cov hlau.
Yuav kom tshem tawm nws, siv ib feem kua txiv qaub dawb thiab ob feem dej sib tov. Siv koj txhuam nylon maj mam txhuam kom txog thaum cov hmoov dawb ploj mus. Yaug kom huv si thiab ziab kom qhuav. Yog tias qhov chaw zoo li tsis ci ntsa iab tom qab ntawd, qhov ntawd yog qhov ib txwm muaj - zinc nyuam qhuav oxidized.
Txawm li cas los xij, yog tias koj pomxeb liab, qhov xwm txheej loj dua. Xeb liab txhais tau tias zinc ploj mus thiab cov hlau tab tom xeb. Thaum lub sijhawm no, koj yuav tsum tshem tawm cov xeb nrog txhuam hlau lossis ntawv xuab zeb, tab sis koj yuav tsum "kho" qhov koj tau ua hauv kev tiv thaiv. Tom qab ntxuav cov xeb liab tawm, thov ib qhotshuaj tsuag galvanizing txias(ib qho primer uas muaj zinc ntau). Qhov no ua tau zoo "kho" cov khaub ncaws ua rog thiab tiv thaiv kom xeb tsis txhob nthuav dav.
Daim Ntawv Teev Npe "Tsis Txhob": Yuav Tsum Tsis Txhob Ua Dab Tsi
Yuav kom koj cov hlau galvanized zoo nkauj tau ntau xyoo, tsis txhob ua peb yam no:
Cov Hlau Wool thiab Cov Txhuam Hlau:Cov no yog ua los ntawm cov hlau carbon. Lawv tso cov hlau me me uas nyob hauv cov zinc. Cov hlau me me ntawd yuav xeb yuav luag tam sim ntawd, ua rau nws zoo li koj cov hlau galvanized puas lawm thaum nws tsuas yog cov seem ntawm koj cov cuab yeej ntxuav xwb.
Muriatic los yog Hydrochloric Acid:Cov no feem ntau siv los ntxuav cov cib lossis cov pob zeb ua vaj tse, tab sis lawv yog "cov neeg tua zinc." Lawv yuav tshem tawm cov galvanization hauv vib nas this, ua rau cov hlau nyoos tsis muaj kev tiv thaiv kiag li.
Tshuaj dawb:Txawm hais tias nws zoo heev rau kev tua pwm, tab sis cov tshuaj dawb ua rau cov hlau uas tsis yog hlau xws li zinc xeb heev. Nws tuaj yeem ua rau cov hlau tawg thiab ua rau cov xim ploj mus tas li.
Cov Lus Qhia Txog Kev Txij Nkawm Zaum Kawg
Cov hlau galvanized nyiam cua nkag. Txoj hauv kev zoo tshaj plaws los ua kom nws huv thiab tsis muaj xeb yog xyuas kom nws qhuav thiab muaj cua nkag tau ntau. Yog tias koj khaws cov kav dej galvanized lossis cov ntawv, tsis txhob muab lawv sib tshooj tiaj tiaj yog tias lawv ntub; ib txwm siv cov spacers kom cua nkag tau nruab nrab ntawm lawv.
Nrog me ntsis xab npum me me, txhuam nylon, thiab kev cog lus tias yuav ua kom cov khoom qhuav, koj cov hlau galvanizedcov khoomtuaj yeem yooj yim kav ntev li 50 xyoo lossis ntau dua.
