Thaum cov pa roj carbon fiber board nyob rau hauv qhov kub ntawm ntau tshaj 400 degree nyob rau hauv qhov chaw uas muaj cov pa oxygen yuav pib oxidized, thiab nrog rau qhov kub thiab txias ntawm sab nraud ib puag ncig, oxidation tus nqi ntawm carbon fiber board maj mam nce, ua rau cov pa roj carbon ntau. fiber board zoo poob, thiaj li hais tias cov khoom ua tau zoo yog txo los yog txawm tsis ua hauj lwm.
Txhawm rau kov yeej cov ntsiab lus no, cov kev ntsuas tseem ceeb uas tuaj yeem ua tau yog kev hloov kho carbon fiber matrix thiab kev hloov kho txheej txheej.
Cia peb tham txog qhov kev hloov kho ntawm cov txheej txheem uas feem ntau siv.
Cov khoom siv carbon fiber ntau raws li cov khoom siv tshiab, txheej txheej txheej txheej txheej ntawm carbon fiber board txawv ntawm cov khoom siv hlau dav dav.
Ib txwm hlau nto ua ntej pleev xim, xav tau degreasing, deg txias, phosphating thiab lwm yam kev kho mob ua ntej, lub hom phiaj yog kom tshem tawm cov kab mob ntawm qhov chaw, txhim kho kev huv thiab roughness, txhim kho corrosion kuj thiab zaj duab xis adhesion.
Carbon fiber board nto du, inert, cov tsoos xim pretreatment txheej txheem yuav tsis tau ib tug zoo phosphate zaj duab xis, nto ntawm tus nqi ntawm cov tsis zoo. Carbon fiber board vim nws cov txheej txheem molding cov yam ntxwv, qhov saum npoo yog yooj yim heev kom muaj pinholes, pits thiab streaks thiab lwm yam tsos mob.
Carbon fiber board pre-painting kev kho mob yog tsuas yog siv los ntxuav cov neeg kho tshuab sanding kev kho mob.
Nws tshem tawm cov hais, pinholes, pits thiab streaks tshwm sim los ntawm cov txheej txheem molding los ntawm kev xuab zeb, thiab ua tiav cov qib siab ntawm qhov roughness, yog li ua rau thaj chaw sib cuag ntawm cov xim los tsim cov nyhuv "tom", thiab txhim kho cov adhesion ntawm cov pa roj carbon monoxide. fiber board thiab txheej zaj duab xis.
Cov pa roj carbon fiber ntau nyob rau hauv qhov kub thiab txias deformation tus nqi yog qhov loj, yog li cov txheej txheem tsis tuaj yeem siv cov txheej txheem kub kub curing txheej txheem, feem ntau txhua txheej ziab kom qhuav txog 80 degree ziab rau li 30 feeb.
Nws txheej txheej feem ntau suav nrog: primer, muab tub lim, xim xim thiab lub tsho sab saum toj.
Cov primer feem ntau yog ob lub ntsiab lus epoxy resin system lossis ob lub ntsiab lus polyurethane nrog cov zaj duab xis qhuav tuab ntawm 30-60 microns, uas muaj cov ntsiab lus siab, ziab sai, kev nkag siab zoo, foob zoo heev, adhesion zoo, zoo. cuam tshuam tsis kam, zoo heev dej tsis kam thiab tsis kam mus rau tshuaj reagents.
Putty feem ntau yog ob lub ntsiab lus tsis txaus ntseeg polyester, lub thickness yuav tsum tsawg dua 1 hli, uas yog qhov ua tau zoo dua kev ua tau zoo, yooj yim rau xuab zeb.
Cov xim pleev xim txheej feem ntau siv ib qho khoom siv polyurethane xim hlau xim, cov yeeb yaj kiab qhuav tuab ntawm 20-40 microns, yuav tsum tau nrog lub tsho "ntub mus rau ntub" txau, uas yog cov xim muaj xim, qib siab xim, muaj zog adhesion, zoo. zais lub zog thiab UV tsis kam.
Lub topcoat feem ntau yog ob lub ntsiab lus polyurethane nrog cov zaj duab xis qhuav tuab ntawm 30-50 microns, uas muaj cov ntsiab lus siab, tsis kub curing, siab gloss, yooj yim polishing, zoo khawb kuj, UV tsis kam, huab cua tsis kam, tsis kam mus ya raws, kub hloov thiab tshuaj reagents.
