1.Dab tsi yog cov teeb meem tseem ceeb thiab kev pheej hmoo cuam tshuam nrog cov xim vuam -coated steel coils?
Txheej Kev puas tsuaj
Weld Zone Kev puas tsuaj: Qhov kub siab ntawm cov hluav taws xob arc (txog li ob peb txhiab degrees Celsius) tuaj yeem hlawv cov xim tam sim ntawd -coated txheej (xim xim, txheej yas) nyob ib ncig ntawm qhov chaw vuam, nthuav tawm cov hlau hauv qab.
Thaum tshav kub kub- Kev puas tsuaj ntawm cheeb tsam: Qhov kub siab uas tsim thaum lub sij hawm vuam yog ua los ntawm cov hlau, ua rau cov txheej sab nraud ntawm qhov vuam taw tes kom tsis muaj xim, hlwv, carbonize, los yog tev tawm vim overheating. Qhov kev puas tsuaj no yuav muaj ntau dua li qhov xav tau.
Poob Corrosion Resistance
Lub luag haujlwm tseem ceeb ntawm txheej txheej ntawm cov xim -coated steel coils yog kev tiv thaiv corrosion. Thaum cov txheej txheej puas lawm, cov hlau uas muaj cov substrate (feem ntau yog galvanized lossis zinc-aluminized steel ntawv) yog ncaj qha rau huab cua thiab noo noo.
Txawm hais tias txheej txheej galvanized kuj tseem kub hnyiab thiab kub hnyiab tau nyob rau hauv qhov kub thiab txias, qhov no tawm ntawm qhov vuam nws tus kheej thiab cov cua sov- cuam tshuam thaj tsam li qhov tsis muaj zog tshaj plaws thiab muaj feem cuam tshuam rau xeb hauv tag nrho cov khoom. Qhov no ho shortens tag nrho lifespan ntawm cov khoom.
Tsim cov pa roj carbon monoxide
Cov organic coatings (polyester, silicone{0}} hloov polyester, PVDF, thiab lwm yam) thiab primers nyob rau hauv cov xim coatings decompose nyob rau hauv kub kub, ua toxic thiab irritating pa taws. Cov pa roj no ua rau muaj kev phom sij rau cov neeg ua haujlwm noj qab haus huv thiab ua paug rau ib puag ncig.
Kev ua pa zoo heev yuav tsum tau ua kom ntseeg tau, thiab cov neeg ua haujlwm yuav tsum hnav cov cuab yeej tiv thaiv ua pa.
cuam tshuam Weld Quality
Cov tshuaj txheej txheej tuaj yeem sib xyaw rau hauv lub pas dej molten thaum lub sij hawm vuam, uas yuav ua rau muaj qhov tsis xws luag xws li porosity thiab slag inclusions, txo lub zog thiab sealing ntawm vuam.
Thaum vuam cov nplooj ntawv galvanized, zinc muaj qhov kub tsis tshua muaj kub (kwv yees li 907 degree) thiab evaporates yooj yim, uas tuaj yeem ua rau muaj qhov porosity thiab tawg hauv qhov vuam.
2.Yuav tsum tau kho li cas ua ntej vuam?
Kev tshem tawm txheej: Cov xim txheej ntawm ob sab ntawm qhov chaw yuav tsum tau welded yuav tsum tau muab tshem tawm kom huv si ua ntej. Qhov chaw tshem tawm yuav tsum txuas ntxiv 20-50mm dhau ntawm txhua sab ntawm cov hlaws tau npaj.
Kev tshem tawm txoj kev: Lub kaum sab xis grinder nrog lub log sib tsoo lossis hlau txhuam, los yog cov tshuaj pleev xim tuaj yeem siv tau. Lub hom phiaj yog kom nthuav tawm tag nrho cov hlau substrate.
3.Yuav xaiv txoj kev vuam zoo li cas?
Resistance qhov chaw vuam: Qhov no yog qhov tsawg heev -kev puas tsuaj rau kev sib koom ua ke rau xim- cov nplooj ntawv hlau vim nws cov cua kub thiab lub sijhawm luv luv. Txawm li cas los xij, cov txheej txheem tseem yuav tsum tau muab tshem tawm ntawm cov ntsiab lus electrode, txwv tsis pub nws yuav cuam tshuam rau conductivity thiab weld zoo.
MIG/MAG welding (gas shielded vuam): Zoo sib xws. Nws raug nquahu kom siv qhov qis dua tam sim no thiab kev sib txuas nrawm dua kom txo tau cov cua sov nkag.
Laser welding: Tsawg cua sov input, me me deformation thiab tshav kub- cuam tshuam cheeb tsam, ua rau nws zoo tshaj plaws vuam txoj kev, tab sis cov cuab yeej siv yog siab.
4.Dab tsi yuav tsum tau ua tom qab vuam?
Ntxuav Vuam Slag: Tom qab vuam, ua tib zoo tshem tawm vuam slag thiab spatter.
Kev tiv thaiv corrosion: Qhov no yog kauj ruam tseem ceeb tshaj plaws; thaj chaw welded thiab tshav kub- thaj tsam cuam tshuam yuav tsum tau kho nrog cov tshuaj tiv thaiv- xeb txheej tam sim ntawd.
Siv Zinc-Ntawv Xim Xim: Qhov no yog txoj hauv kev tshaj plaws. Ua ntej, ntxuav qhov saum npoo nrog txhuam txhuam, tom qab ntawd siv qhov tshwj xeeb siab -zinc-cov ntsiab lus los tiv thaiv- corrosion primer. Nws txoj cai tiv thaiv -corrosion zoo ib yam li galvanizing (cathode tiv thaiv).
Siv Hnyav -Lub Luag Haujlwm Tiv Thaiv- Corrosion Coatings xws li Epoxy Resin Xim.
Yuav Tsum Tau: Qhov zoo tshaj plaws, siv cov primer ua ntej, ua raws li topcoat. Cov xim pleev xim rau sab saum toj yuav tsum sib phim cov xim xim qub kom ze li sai tau kom ua tiav ob qho tib si tiv thaiv -corrosion thiab zoo nkauj.
5.Puas muaj lwm txoj kev zoo dua?
Tus kheej -tapping screws / rivets: Qhov no yog txoj hauv kev zoo tshaj plaws rau kev txhim kho xim -coated steel ntawv. Lawv tsis ua rau thaj chaw loj ntawm cov txheej txheej, ua kom nrawm rau nruab, thiab tsis tshua muaj nqi.
Interlocking pob qij txha: Feem ntau siv rau longitudinal pob qij txha ntawm cov xim -coated steel coils, cov kev sib txuas no ua tiav los ntawm kev sib cuam tshuam txhua yam, tshem tawm tag nrho cov cua sov- thaj chaw cuam tshuam.
Structureal adhesive bonding: Rau qee yam uas tsis yog-load-cov kabmob lossis cov khoom hnyav-cov kabmob, siab-kev ua haujlwm ntawm cov nplaum nplaum tuaj yeem siv rau kev sib txuas, kom tsis txhob muaj teeb meem siab - kub.
