Painting Cov Khoom Siv Fiber ntau yuav tsum muaj cov txuj ci tshwj xeeb los xyuas kom meej cov adceionion, durability, thiab zoo nkauj zoo thaum khaws cov ntaub ntawv kev ntseeg siab. Tsis zoo li cov hlau lossis cov plastics, carbon fiber txoj kev ua kom haum, cov chaw mos thiab cov txheej txheem txheej txheej uas tsis muaj txiaj ntsig thiab cov khoom siv nplua nuj rau xim sib tw. Ntawm no yog cov lus qhia meej ntawm cov txheej txheem:
Npaj Npaj Ntev
Thawj kauj ruam muaj kev tu tsis zoo rau tshem tawm cov paug tsis huv xws li cov tshuaj tso tawm, roj, lossis hmoov av. Puas yog yog qhov tseem ceeb: maj mam sanding saum npoo nrog 400-800 grit sandpaper tsim cov ntawv me me rau cov tshuab ua haujlwm. Qee cov tuam ntxhab siv kev kho ntshav lossis tshuaj etching mus txhim kho lub zog saum npoo. Ib qho kev siv dej sov (isopropyl cawv lossis acetone) ua raws li tshem tawm cov lus seem.
Phau ntawv thov
Lub siab-adhesion epoxy lossis urethane primer yog txau hauv cov nyias, txawm tias lub tsho ntev. No txheej txuas tus kab mob carbon fiber ntau inert nto thiab cov xim, tiv thaiv cov ntses lossis tev. Ob-feem primers tau nyiam rau lawv cov tshuaj tiv thaiv. Kev kho cov sijhawm sib txawv tab sis feem ntau koom nrog kev ziab qhuav lossis cov cub siv hluav taws xob influled.
Baskoat Thiab Cov Qauv Xim
Kev siv cov xim tsheb-qib polyurethane yog cov xim siv rau lawv qhov yooj thiab UV tsis kam. Ntau lub tsho muaj lub teeb tau thov zam kom tsis txhob muaj kev qaug zog, nrog cov phiaj xwm flash tawm ntawm cov khaubncaws sab nraud povtseg. Kev cai xim lossis nws yog xim hlau tiav yuav xav tau Tinted Basecoats. Rau cov pa roj carbon fiber cov fiber cov ntaub ntawv kom pom tau pom, pob tshab zas yog qhov kev xaiv.
Kev Tiv Thaiv Clincoat
Ib tug siab-ci lossis matte clearcoat (feem ntau acrylic-polyurethane) ntsaws cov xim pleev xim. Cov txheej txheem no tawm ntawm cov khawb ntoo, tshuaj lom neeg, thiab UV degradation. Cov ntawv thov kev tshaj lij feem ntau koom nrog 2-3 Clearcoat txheej, sanded ntawm lub tsho rau iav zoo li smoothness.
Kho thiab xov
Thaum tshav kub kho ntawm 60-80 degree accelerates cross-txuas ntawm cov xim tha xim polymers, txhim kho hardness. Tom qab-kho, ib tug kawg polish nrog zuj zus finer compounds (txog 3000 grit) tshem tawm cov txiv kab ntxwv typures txiv kab ntxwv.
Cov kev txiav txim siab tseem ceeb
Cov khoom siv tau sib xws: Xyuas kom cov xim tsev thiab cov kuab tshuaj tsis hnov mob nrog cov pa roj carbon fiber ntau lub matrix.
Ib puag ncig tswj: Lub rooj muag av plua plav nrog cov av noo tiv thaiv paug.
Kev Tswj Thickness: Cov xim ntau dhau tuaj yeem ua rau muaj roj carbon fiber ntau-txuag cov txiaj ntsig.
Kev xyuas xim: Kev ua pa rau hauv lub cev thiab kev ua pa yog qhov yuav tsum tau ua rau cov av tsis huv (vocs).
Kev lag luam loj ua rau cov tshuaj tsuag hluav taws xob robotic rau kev sib xws, Thaum DIY txaus siab feem ntau siv cov khoom siv ua ntej cov pa roj carbon ntau ntau zaus. Raug tua kom raug, pleev xim rau carbon fiber ntau khaws nws lub zog thiab tau txais kev ua kom zoo nkauj rau kev kho tsheb, aerospace, lossis cov neeg siv khoom siv.
