Nov yog yam koj yuav tsum paub txog keeb kwm ntawm automotive txheej

Thaum koj pom lub tsheb, koj qhov kev xav thawj zaug tej zaum yuav yog xim ntawm lub cev.Niaj hnub no, muaj cov xim zoo nkauj ci ntsa iab yog ib qho ntawm cov qauv tsim rau kev tsim tsheb.Tab sis ntau tshaj li ib puas xyoo dhau los, kev pleev xim rau lub tsheb tsis yog ib txoj haujlwm yooj yim, thiab nws tsis zoo nkauj dua li niaj hnub no.Lub tsheb pleev xim tau hloov zuj zus mus rau qhov nws muaj hnub no li cas?Surley yuav qhia koj txog keeb kwm ntawm kev tsim kho tsheb xim txheej tshuab.

Kaum vib nas this kom nkag siab cov ntawv nyeem:

1,Lacqueroriginated nyob rau hauv Tuam Tshoj, sab hnub poob coj tom qab lub industrial kiv puag ncig.

2, Cov khoom siv ntuj tsim xim dries maj mam, cuam tshuam rau kev ua haujlwm ntawm kev tsim tsheb, DuPont tau tsim kom qhuav sai.nitro xim.

3, Txau phomhloov cov txhuam hniav, muab cov xim pleev xim ntau dua.

4, Los ntawm alkyd rau acrylic, kev nrhiav kev ua haujlwm ntev thiab kev sib txawv yog tsis tu ncua.

5, Los ntawm "txhaj tshuaj" mus rau "dip txheej"Nrog lacquer da dej, qhov nruam nrhiav qhov zoo ntawm cov xim tuaj rau phosphating thiab electrodeposition tam sim no.

6, Hloov nrogpleev xim rau dejnrhiav kev tiv thaiv ib puag ncig.

7, Tam sim no thiab yav tom ntej, kev siv thev naus laus zis tau dhau los ua ntau dua li kev xav,txawm tsis muaj xim.

Lub luag haujlwm tseem ceeb ntawm cov xim yog los tiv thaiv kev laus

Cov neeg feem coob xav txog lub luag haujlwm ntawm cov xim yog muab cov khoom ci ntsa iab, tab sis los ntawm kev tsim khoom lag luam, xim yog qhov xav tau thib ob;xeb thiab tiv thaiv kev laus yog lub hom phiaj tseem ceeb.Los ntawm cov hnub thaum ntxov ntawm cov hlau-ntoo ua ke mus rau cov ntshiab hlau dawb lub cev niaj hnub no, lub tsheb lub cev xav tau xim raws li cov txheej txheem tiv thaiv.Cov teeb meem uas cov xim txheej yuav tsum tau ntsib yog kev hnav thiab tsim kua muag xws li lub hnub, xuab zeb thiab nag, kev puas tsuaj rau lub cev xws li khawb, txhuam thiab kev sib tsoo, thiab kev yaig xws li ntsev thiab tsiaj txhu.Nyob rau hauv cov evolution ntawm painting technology, cov txheej txheem yog maj mam txhim kho ntau thiab ntau npaum thiab check thiab zoo nkauj tawv nqaij rau lub cev ua hauj lwm kom tau raws li cov kev cov nyom.

Lacquer los ntawm Tuam Tshoj

Lacquer muaj keeb kwm ntev heev thiab, txaj muag, txoj hauj lwm hauv lacquer technology tau koom nrog Tuam Tshoj ua ntej Industrial Revolution.Kev siv lacquer hnub rov qab mus txog rau lub sijhawm Neolithic, thiab tom qab Warring States lub sijhawm, craftsmen siv tung roj muab rho tawm los ntawm cov noob ntawm tsob ntoo tung thiab ntxiv natural raw lacquer los ua ib tug sib tov ntawm cov xim, txawm hais tias lub sij hawm ntawd lacquer yog. khoom kim heev rau cov nom tswv.Tom qab tsim Ming Dynasty, Zhu Yuanzhang pib teeb tsa tsoomfwv lacquer kev lag luam, thiab xim tshuab tsim sai heev.Thawj Suav ua haujlwm ntawm cov xim thev naus laus zis, "The Book of Painting", tau sau los ntawm Huang Cheng, tus tsim lacquer hauv Ming Dynasty.Ua tsaug rau kev txhim kho kev lag luam thiab kev lag luam sab hauv thiab sab nraud, lacquerware tau tsim cov khoom siv tes ua lag luam paub tab hauv Ming Dynasty.

Zheng He yog cov khoom muaj nqis nkoj

Cov tung roj pleev xim zoo tshaj plaws ntawm Ming Dynasty yog tus yuam sij rau nkoj tsim khoom.Lub xyoo pua puas xyoo Spanish kws tshawb fawb Mendoza tau hais hauv "History of the Greater China Empire" tias Suav cov nkoj coated nrog tung roj muaj ob zaug lub neej ntawm cov nkoj nyob sab Europe.

Nyob rau hauv nruab nrab ntawm lub xyoo pua 18th, cov teb chaws Europe thaum kawg tawg thiab mastered thev naus laus zis ntawm tung roj pleev xim, thiab European xim kev lag luam maj mam hloov.Cov khoom siv raw tung roj, ntxiv rau kev siv lacquer, kuj yog ib qho tseem ceeb raw khoom rau lwm yam lag luam, tseem monopolized los ntawm Tuam Tshoj, thiab tau los ua ib qho tseem ceeb muaj raw khoom rau ob industrial revolutions mus txog rau thaum ntxov 20th caug xyoo, thaum lub tung ntoo hloov. nyob rau hauv North thiab South America tau zoo li, uas rhuav Tuam Tshoj txoj kev monopoly ntawm raw khoom.

Kev ziab tsis siv sijhawm ntev txog 50 hnub

Nyob rau hauv lub xyoo pua 20th thaum ntxov, tsheb tseem tau tsim los siv cov xim ntuj xim xws li cov roj linseed ua ib daim ntawv khi.

Txawm tias Ford, uas tau pioneer cov kab ntau lawm los tsim tsheb, tsuas yog siv cov Japanese dub xim yuav luag mus rau qhov siab tshaj plaws nyob rau hauv thiaj li yuav nrhiav kev tsim ceev vim nws dries sai tshaj plaws, tab sis tom qab tag nrho, nws tseem yog ib tug natural puag cov ntaub ntawv xim, thiab cov xim txheej tseem. xav tau ntau tshaj ib lub lim tiam kom qhuav.

Hauv xyoo 1920, DuPont tau ua haujlwm ntawm cov xim nitrocellulose sai qhuav (aka nitrocellulose xim) uas ua rau cov neeg ua haujlwm luag nyav, tsis tas yuav ua haujlwm ntawm cov tsheb nrog cov xim ntev li no.

Los ntawm 1921, DuPont twb yog ib tug thawj coj nyob rau hauv lub tsim ntawm nitrate motion duab films, raws li nws tig mus rau nitrocellulose-raws li cov khoom uas tsis yog-explosives los nqus cov loj muaj peev xwm chaw nws tau tsim thaum lub sij hawm tsov rog.Nyob rau yav tsaus ntuj hnub Friday kub thaum Lub Xya Hli 1921, ib tus neeg ua haujlwm ntawm DuPont zaj duab xis cog tau tso ib lub thoob ntawm nitrate paj rwb fiber ntau rau ntawm qhov chaw nres nkoj ua ntej tawm haujlwm.Thaum nws rov qhib dua rau hnub Monday sawv ntxov, nws pom tias lub thoob tau hloov mus rau hauv cov kua ntshiab, uas tom qab ntawd los ua lub hauv paus rau cov xim nitrocellulose.Xyoo 1924, DuPont tau tsim DUCO nitrocellulose xim, siv nitrocellulose ua cov khoom siv tseem ceeb thiab ntxiv cov khoom siv hluavtaws, plasticizers, cov kuab tshuaj thiab cov thinners los muab nws.Qhov txiaj ntsig zoo tshaj plaws ntawm cov xim nitrocellulose yog tias nws qhuav sai, piv rau cov xim ntuj xim uas yuav siv sij hawm ib lub lim tiam lossis ib lub lis piam kom qhuav, cov xim nitrocellulose tsuas yog siv sij hawm 2 teev kom qhuav, ua kom cov xim nrawm nrawm dua.Xyoo 1924, yuav luag tag nrho cov kab ntau lawm ntawm General Motors siv Duco nitrocellulose xim.

Lawm, cov xim nitrocellulose muaj nws cov drawbacks.Yog tias txau rau hauv qhov chaw ntub dej, zaj duab xis yuav yooj yim tig dawb thiab poob nws cov luster.Cov xim pleev xim rau saum npoo muaj qhov tsis zoo corrosion tsis zoo rau cov roj av-raws li cov kuab tshuaj, xws li roj av, uas tuaj yeem ua rau cov xim pleev xim, thiab cov roj roj uas ntws tawm thaum lub sij hawm refueling tuaj yeem ua kom cov xim tsis zoo nyob ib puag ncig.

Hloov cov txhuam hniav nrog rab phom tsuag los daws cov xim tsis sib xws

Ntxiv nrog rau cov yam ntxwv ntawm cov xim nws tus kheej, txoj kev pleev xim kuj tseem ceeb heev rau lub zog thiab kav ntev ntawm cov xim pleev xim.Kev siv cov tshuaj tsuag phom yog ib qho tseem ceeb hauv keeb kwm ntawm painting technology.Cov tshuaj tsuag phom tau nkag mus rau hauv kev lag luam pleev xim hauv xyoo 1923 thiab hauv kev lag luam tsheb hauv xyoo 1924.

DeVilbiss tsev neeg yog li tsim DeVilbiss, lub tuam txhab muaj npe nrov hauv ntiaj teb tshwj xeeb hauv kev siv tshuab atomization.Tom qab ntawd, Alan DeVilbiss tus tub, Tom DeVilbiss, tau yug los.Dr. Alan DeVilbiss 'tus tub, Tom DeVilbiss, coj nws txiv txoj kev tsim tawm dhau ntawm kev kho mob.DeVilbiss coj nws txiv qhov kev tsim tawm dhau los ntawm kev kho mob thiab hloov pauv tus thawj atomizer rau hauv rab phom txau rau kev pleev xim.

Nyob rau hauv lub tshav pob ntawm kev lag luam painting, txhuam tau sai heev los ntawm cov tshuaj tsuag phom.deVilbiss tau ua hauj lwm nyob rau hauv lub teb ntawm atomization rau ntau tshaj 100 xyoo thiab tam sim no yog tus thawj coj nyob rau hauv lub teb ntawm industrial spray phom thiab atomizers kho mob.

Los ntawm alkyd rau acrylic, ntau ruaj thiab muaj zog

Nyob rau xyoo 1930, alkyd resin enamel xim, hu ua alkyd enamel xim, tau nkag mus rau hauv cov txheej txheem automotive painting.Cov hlau ntawm lub tsheb lub cev tau txau nrog cov xim no thiab tom qab ntawd ziab hauv qhov cub los ua cov xim pleev xim zoo nkauj heev.Piv rau cov xim nitrocellulose, cov xim alkyd enamel yog siv sai dua, tsuas yog 2 mus rau 3 kauj ruam piv rau 3 mus rau 4 kauj ruam rau cov xim nitrocellulose.Cov xim enamel tsis tsuas yog qhuav sai, tab sis kuj tiv taus cov kuab tshuaj xws li roj av.

Qhov tsis zoo ntawm alkyd enamels, txawm li cas los xij, yog tias lawv ntshai lub hnub ci, thiab nyob rau hauv tshav ntuj cov xim zaj duab xis yuav oxidized ntawm tus nqi nrawm thiab cov xim yuav sai sai ploj mus thiab ua npub, qee zaum cov txheej txheem no tuaj yeem nyob hauv ob peb lub hlis xwb. .Txawm hais tias lawv qhov tsis zoo, alkyd resins tsis tau raug tshem tawm tag nrho thiab tseem yog ib feem tseem ceeb ntawm cov txheej txheem niaj hnub no.Thermoplastic acrylic xim tau tshwm sim nyob rau hauv 1940s, zoo heev txhim kho cov hniav thiab durability ntawm lub tiav, thiab nyob rau hauv 1955, General Motors pib painting tsheb nrog ib tug tshiab acrylic resin.Lub rheology ntawm cov xim no yog qhov tshwj xeeb thiab yuav tsum tau txau ntawm cov ntsiab lus qis, yog li xav tau ntau lub tsho loj.Qhov zoo li qhov tsis zoo no yog qhov zoo dua thaum lub sijhawm vim nws tso cai rau kev suav nrog cov hlau flakes hauv txheej.Cov kua roj vanish acrylic tau txau nrog cov viscosity qis heev, tso cai rau cov hlau flakes yuav tsum flattened los ua ib txheej reflective, thiab tom qab ntawd cov viscosity tau nce sai heev los tuav cov hlau flakes nyob rau hauv qhov chaw.Yog li, cov xim hlau tau yug los.

Nws yog ib nqi sau cia hais tias lub sij hawm no pom ib tug cia li ua ntej nyob rau hauv acrylic xim technology nyob rau hauv cov teb chaws Europe.Qhov no tshwm sim los ntawm kev txwv tsis pub dhau lub tebchaws European Axis tom qab Tsov Rog Ntiaj Teb Zaum II, uas txwv tsis pub siv qee cov khoom siv tshuaj hauv kev tsim khoom, xws li nitrocellulose, cov khoom siv raw xav tau rau cov xim nitrocellulose, uas tuaj yeem siv los ua cov khoom tawg.Nrog rau qhov kev txwv no, cov tuam txhab hauv cov tebchaws no tau pib tsom mus rau cov xim pleev xim pleev xim, tsim cov xim acrylic urethane.Thaum European xim nkag mus rau Tebchaws Meskas hauv xyoo 1980, Asmeskas cov tsheb pleev xim tshuab tau nyob deb ntawm European cov neeg sib tw.

Automated txheej txheem ntawm phosphating thiab electrophoresis rau kev nrhiav cov xim zoo nkauj

Ob xyoo caum tom qab Tsov Rog Ntiaj Teb Zaum II yog lub sijhawm ua kom zoo ntawm lub cev txheej txheej.Nyob rau lub sijhawm no hauv Tebchaws Meskas, ntxiv rau kev thauj mus los, tsheb kuj muaj tus cwj pwm ntawm kev txhim kho kev sib raug zoo, yog li cov tswv tsheb xav kom lawv lub tsheb zoo dua qub, uas yuav tsum muaj cov xim zoo nkauj dua thiab cov xim zoo nkauj dua.

Pib xyoo 1947, cov tuam txhab tsheb pib phosphatize hlau nto ua ntej pleev xim, ua ib txoj hauv kev los txhim kho cov adhesion thiab corrosion kuj ntawm cov xim.Cov primer kuj tau hloov los ntawm cov tshuaj tsuag mus rau dip txheej, uas txhais tau hais tias lub cev qhov chaw tau dipped rau hauv lub pas dej ua ke ntawm cov xim, ua kom nws zoo ib yam thiab cov txheej txheem ntau dua, kom ntseeg tau tias qhov nyuaj-mus txog qhov chaw xws li kab noj hniav kuj tuaj yeem pleev xim rau. .

Nyob rau xyoo 1950, cov tuam txhab tsheb tau pom tias txawm tias siv cov txheej txheem dip txheej, ib feem ntawm cov xim tseem yuav raug ntxuav tawm hauv cov txheej txheem tom ntej nrog cov kuab tshuaj, txo cov txiaj ntsig ntawm kev tiv thaiv xeb.Txhawm rau daws qhov teeb meem no, xyoo 1957, Ford koom nrog PPG hauv kev coj noj coj ua ntawm Dr. George Brewer.Raws li kev coj noj coj ua ntawm Dr. George Brewer, Ford thiab PPG tau tsim cov txheej txheem electrodeposition txheej txheem uas tam sim no feem ntau siv.

 

Ford tom qab ntawd tsim lub ntiaj teb thawj anodic electrophoretic xim khw hauv 1961. Cov txheej txheem pib yog qhov tsis zoo, txawm li cas los xij, thiab PPG tau qhia txog cov txheej txheem zoo tshaj plaws cathodic electrophoretic txheej thiab cov txheej txheem sib xws hauv xyoo 1973.

Xim kom kav ntev kom zoo nkauj kom tsis txhob muaj kuab paug rau cov xim pleev xim dej

Nyob rau hauv nruab nrab mus rau lig 70's, kev paub txog kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig los ntawm kev kub ntxhov roj kuj muaj kev cuam tshuam zoo rau kev lag luam xim.Nyob rau hauv lub 80s, lub teb chaws tau enacted tshiab volatile organic compound (VOC) cov kev cai, uas ua acrylic xim coatings nrog siab VOC cov ntsiab lus thiab tsis muaj zog durability tsis kam mus rau lub lag luam.Tsis tas li ntawd, cov neeg siv khoom kuj xav tias cov xim pleev xim rau lub cev yuav kav ntev li 5 xyoos, uas yuav tsum tau hais txog qhov ua tau zoo ntawm cov xim tiav.

Nrog cov pob tshab lacquer txheej raws li cov txheej txheem tiv thaiv, cov xim xim sab hauv tsis tas yuav tsum yog tuab li ua ntej, tsuas yog ib txheej nyias nyias uas xav tau rau kev kho kom zoo nkauj.UV absorbers kuj tau ntxiv rau txheej lacquer los tiv thaiv cov xim hauv cov pob tshab txheej thiab cov primer, ua kom lub neej ntawm primer thiab xim xim.

Cov txheej txheem tha xim yog pib raug nqi thiab feem ntau tsuas yog siv rau cov qauv high-end.Tsis tas li ntawd, lub durability ntawm lub tsho tiv no tsis zoo, thiab nws yuav sai sai flake tawm thiab yuav tsum tau repainting.Hauv kaum xyoo tom ntej, txawm li cas los xij, kev lag luam tsheb thiab kev lag luam pleev xim tau ua haujlwm los txhim kho cov txheej txheem thev naus laus zis, tsis yog los ntawm kev txo tus nqi xwb tab sis kuj los ntawm kev tsim kho tshiab saum npoo uas ua rau lub neej ntawm lub tsho ntshiab.

Qhov kev ua kom zoo nkauj painting technology

Yav tom ntej txheej txheej tseem ceeb ntawm txoj kev loj hlob, qee cov neeg hauv kev lag luam ntseeg tias tsis muaj duab kos duab.Cov thev naus laus zis no tau nkag mus rau hauv peb lub neej tiag tiag, thiab lub plhaub ntawm txhua hnub rau cov khoom siv hauv tsev tau siv cov tshuab tsis muaj xim.Lub plhaub ntxiv cov xim sib xws ntawm nano-theem hlau hmoov hauv cov txheej txheem txhaj tshuaj molding, ncaj qha tsim cov plhaub nrog cov xim ci ntsa iab thiab cov xim hlau zoo nkauj, uas tsis tas yuav tsum tau pleev xim rau tag nrho, zoo heev txo cov pa phem uas tsim los ntawm kev pleev xim.Lawm, nws kuj yog siv dav hauv tsheb, xws li trim, grille, rearview daim iav plhaub, thiab lwm yam.

Ib txoj hauv kev zoo sib xws yog siv hauv cov hlau, uas txhais tau hais tias yav tom ntej, cov khoom siv hlau uas siv tsis tau pleev xim yuav twb muaj cov txheej txheem tiv thaiv lossis txawm tias xim txheej ntawm lub Hoobkas.Cov thev naus laus zis no yog tam sim no siv nyob rau hauv aerospace thiab tub rog sector, tab sis nws tseem nyob deb ntawm kev siv pej xeem, thiab nws tsis tuaj yeem muab ntau yam xim.

Cov ntsiab lus: Los ntawm txhuam mus rau rab phom mus rau cov neeg hlau, los ntawm cov nroj tsuag ntuj xim rau cov tshuaj pleev xim rau high-tech, los ntawm kev nrhiav kev ua haujlwm zoo mus rau kev ua haujlwm zoo rau kev nrhiav kev noj qab haus huv ib puag ncig, kev nrhiav kev pleev xim thev naus laus zis hauv kev lag luam tsheb tsis tau nres, thiab cov degree ntawm technology yog nce thiab siab dua.Cov neeg pleev kob uas siv los tuav cov txhuam hniav thiab ua haujlwm nyob rau hauv ib puag ncig hnyav yuav tsis xav tias niaj hnub no cov xim ntawm lub tsheb tau nce siab heev thiab tseem tab tom tsim.Lub neej yav tom ntej yuav yog lub sijhawm zoo ib puag ncig, txawj ntse thiab muaj txiaj ntsig zoo.
