Ntau tus neeg tsav tsheb paub tias qhov zoo ntawm lub tsheb thauj khoom tsis raug txiav txim los ntawm cov hlau ib leeg- cov xim tiav kuj yog ib qho tseem ceeb qhia txog nws cov kav ntev. Feem ntau hais lus, ib qho khoom siv zoo nkauj tuaj yeem ua kom nws cov txheej txheem zoo li peb mus rau plaub xyoos; dhau ntawd, nws yuav nyuaj heev. Tsis zoo li lwm yam khoom siv, lub tsheb thauj khoom raug muab tso rau qhov kev sim thaum nws tawm hauv lub Hoobkas - tsis tu ncua raug rau lub hnub thiab cua, tawg los ntawm pob zeb, thiab hnav los ntawm cov khoom thauj.
Common drawbacks ntawm phau ntawv spray painting
Tam sim no, feem ntau cov tsheb thauj khoom ntawm kev ua lag luam tseem vam khom cov tshuaj pleev xim pleev xim ib txwm siv. Cov txheej txheem yog yooj yim thiab raug nqi - zoo, uas yog vim li cas nws thiaj li tau siv dav hauv cov qauv - cov khoom zoo. Txawm li cas los xij, tus nqi qis feem ntau tuaj nrog qhov tsis zoo:
1. Nyuaj-rau- mus txog thaj chaw thiab cov ces kaum feem ntau sab laug tsis muaj coated
2. Cov xim tsis sib xws, nrog kev sib txawv ntawm qhov chaw
3. Yooj yim rau tev tom qab khoov lossis compression; txwv corrosion thiab xeb kuj, uas ua rau tsis zoo durability
4. Cov khoom siv pov tseg ntau dua thiab kev siv hluav taws xob ntau dua, ua rau nws tsis tshua muaj kev cuam tshuam ib puag ncig
"Raws li cov lus hais mus, cov txheej txheem dhau los ua rau raug ntaus." Kev lig kev cai, cov txheej txheem tsawg dua tuaj yeem ua tsis tau raws li cov kev xav tau ntawm kev lag luam niaj hnub no. Cov neeg tsav tsheb niaj hnub tab tom nrhiav rau siab dua - cov kev daws teeb meem zoo - cov txheej txheem uas muaj kev tiv thaiv corrosion zoo dua thiab hnav tsis kam los hloov cov ntawv pleev xim pleev xim.
Qhov no yog qhov chaw electrophoretic txheej (e-coating) los rau hauv. Txij li xyoo 1950, thaum thawj e- txheej txheej txheej tau nthuav tawm hauv kev lag luam tsheb, thev naus laus zis tau maj mam nthuav dav thiab ua kom zoo dua qub. Txawm li cas los xij, hauv kev lag luam trailer, e- txheej tau qeeb kom tau txais kev saws me nyuam. Qhov laj thawj yog qhov yooj yim: qhov ua tiav e- txheej txheej txheej yuav tsum muaj kev nqis peev tseem ceeb, ib qho uas feem ntau cov tuam txhab trailer tsuas tsis tuaj yeem them taus.
Electrophoretic Txheej - Thawj Kab Kev Tiv Thaiv rau Trailer Lub Cev
Dab tsi tiag tiag ua rau e- txheej txheej zoo li nws cov corrosion kuj, hnav tsis kam, thiab kev cuam tshuam ntev tshaj li cov xim pleev xim? Txhawm rau teb cov lus nug no, peb tau tham nrog cov kws tshaj lij engineers ntawm Oriental Vehicles thiab sau qee qhov kev nkag siab los ntawm lawv cov kws tshaj lij.
Electrophoretic txheej yog dej- txheej txheem pleev xim. Nyob rau hauv cov txheej txheem no, cov ntaub ntawv txheej dissolves nyob rau hauv dej mus rau hauv zaj duab xis - tsim hais, uas tsiv mus rau lub opposite electrode nyob rau hauv ib tug ncaj qha tam sim no hluav taws xob teb thiab tso rau saum npoo ntawm lub workpiece, tsim ib tug uniform txheej txheej.
Txawm hais tias nws yuav suab ncaj nraim, thev naus laus zis tom qab nws yog qhov nyuaj dua li cov tshuaj pleev xim rau cov pa. Lub tsheb thauj khoom kho nrog e- txheej tsis muaj "nyuaj-mus rau- mus txog" thaj chaw-txhua lub ces kaum, txawm tias cov seem zais, tau them tag nrho. Cov txheej tuab kuj zoo ib yam thoob plaws lub cev. Qhov tseem ceeb tshaj plaws, nws hloov cov xim pleev xim rau hauv qhov trailer thawj kab ntawm kev tiv thaiv.
Qhov sib txawv ntawm lub zog thiab hnav tsis kam ntawm e- txheej thiab cov xim zoo sib xws yog ntiaj teb sib nrug.
Tab sis qhov ntawd puas txhais tau hais tias lub tsheb thauj khoom tau nce mus txog saum - qib corrosion thiab hnav tsis kam tom qab e{1}} txheej? Tsis raws nraim. E- txheej txheej ua haujlwm raws li txheej txheej primer- txheej txheem topcoat yog ib qho tseem ceeb.
Thaum nws los txog rau topcoat, feem ntau cov tuam txhab lag luam tseem xaiv cov tshuaj tsuag tshuaj pleev ib ce, thaum cov neeg nrhiav kev zoo dua yuav xaiv cov hmoov txheej hloov.
Dab tsi yog qhov zoo ntawm cov hmoov txheej?
Raws li paub zoo, cov tshuaj pleev xim ib txwm siv tsuas yog siv cov xim pleev xim rau hauv lub tsheb, thaum hmoov txheej siv electrostatic hmoov txau-tseem hu ua hmoov txheej lossis txheej txheej electrostatic.
Raws li cov kws tshaj lij engineers ntawm Oriental Vehicles, cov txheej txheem hmoov txheej siv cov phom tshwj xeeb electrostatic tsuag. Cov hmoov yog pub rau hauv rab phom nrog cov cua compressed, thiab thaum nws dhau los ze ntawm corona tawm electrode, cov khoom ua rau tsis zoo, tsim hluav taws xob electrostatic thiab dipole rog.
Tsav los ntawm huab cua siab, cov khoom siv hluav taws xob no tawm ntawm rab phom tsuag thiab taug kev raws cov kab hluav taws xob mus rau qhov chaw ua haujlwm zoo. Tom qab ntawd lawv faib lawv tus kheej raws li qhov ceev ntawm qhov hluav taws xob ntawm qhov chaw, tso cai rau cov hmoov ua kom ruaj khov thiab sib npaug rau lub substrate.
Tom qab cov txheej txheem txau, cov hmoov txheej yuav tsum muaj ib kauj ruam ntxiv: siab -kub curing. Thaum ci thiab kho kom zoo, cov txheej txheej ua ib qho nyuaj, tiv thaiv txheej ruaj khov rau ntawm lub tsheb. Yog li ntawd, hmoov txheej muaj qhov zoo dua adhesion thiab corrosion tsis kam tshaj li cov tshuaj tsuag pleev xim.
E-coating + Powder Txheej - Ib qho tiav uas tuaj yeem kav mus txog xya xyoo
Nrog rau cov txheej txheem sib xyaw ua ke ntawm e- txheej thiab hmoov txheej, lub tsheb thauj khoom tuaj yeem tswj xyuas nws cov xim ncaj ncees txog li xya xyoo nyob rau hauv ib txwm ua haujlwm. Ob peb lub tsheb thauj khoom ntawm kev ua lag luam muaj peev xwm xa tau ob qho tib si e- txheej thiab hmoov txheej raws li kev ua tiav -Oriental Vehicles semi-trailers yog ntawm lawv.
Ua tsaug rau qhov kev sib xyaw ua ke zoo tshaj plaws no, lawv cov kev ua tau zoo hauv kev hnav thiab corrosion kuj yog ib qho zoo tshaj plaws hauv kev lag luam. Nws kuj qhia txog Oriental Vehicles 'ntev- kev cog lus ruaj khov: lub tsev muaj zog dua, ruaj khov dua ib nrab-trailers.
Ib tug muaj zog semi-trailer yuav tsum, qhov tseem ceeb tshaj plaws, yuav ruaj. Thiab ib qho kev ruaj khov tiag tiag yuav tsum nyob hauv qhov zoo txawm tias tom qab raug tshav ntuj, cua, thiab cov khoom thauj.
Yog vim li cas yooj yim - cov xim tiav yog ib txwm thawj kab ntawm kev tiv thaiv tiv thaiv cov hlau. Yog tias cov txheej txheem tsis tuaj yeem xa mus ntev - lub sij hawm corrosion thiab hnav tsis kam, ces txhua qhov kev thov ntawm kev ua haujlwm ntev yog qhov tsis muaj kev sib tham.
