Carbon fiber ntauyog tus sawv cev ntawm cov khoom siv ua haujlwm siab nyob rau theem tam sim no.Yog vim li cas yog cov khoom siv carbon fiber ntau muaj zog zoo heev.Hauv kev siv tswv yim, qhov zoo ntawm lub teeb yuag yog cov ntaub ntawv carbon fiber ntau tuaj yeem hloov cov khoom siv hlau zoo dua qub.Qhov zoo ntawm lub teeb ci ntawm cov khoom, nyob rau hauv qee qhov chaw tshwj xeeb, kuj tseem muaj cov kev xav tau siab rau kev tiv thaiv corrosion ntawm cov khoom, yog li cov roj carbon fiber ntau corrosion resistant?Qhov tsab xov xwm no yuav ua raws li tus editor mus saib.
Lub corrosion kuj ntawm carbon fiber ntau heev.Qhov no yog vim cov qauv kev ruaj ntseg ntawm cov tawg fiber ntau ua rau nws.Kev tsim cov khoom siv carbon fiber ntau yuav tsum tau ua kom zoo nyob rau hauv ntau txhiab C kom tshem tawm cov impurities sab hauv thiab cov ntsiab lus carbon.Cov txheej txheem ntawm lithification tsim cov qauv carbon microcrystalline.Cov khoom siv no muaj qhov zoo ntawm qhov nruab nrab siab corrosion kuj.Nyob rau hauv ib puag ncig ntawm 50% hydrochloric acid los yog sulfuric acid phosphoric acid, tag nrho cov cuab yeej cuab tam tau ua qauv hauv kev nthuav dav.Nrog rau txoj kab uas hla ntawm ob txhais ceg yuav tsis hloov pauv zoo heev, uas tseem ua rau muaj txiaj ntsig zoo rau kev yaig tsis kam ntawm cov khoom siv fiber ntau.Qhov no ua kom ntseeg tau tias cov pa roj carbon fiber ntau muaj txiaj ntsig zoo hauv kev tiv thaiv corrosion.
Nws tuaj yeem pom tias cov pa roj carbon fiber ntau muaj kev ua haujlwm siab corrosion kuj.Tab sis raucarbon fiber ntauCov khoom lag luam, qhov no tsis yog qhov tsim nyog, vim tias cov fiber ntau ntshiab tsis tuaj yeem ua rau nws tus kheej ua rau cov khoom siv fiber ntau.Yog tias nws xav tau cov khoom siv matrix, cov khoom siv feem ntau yog cov khoom siv matrix resin, thiab corrosion kuj ntawm cov khoom siv fiber ntau zoo ib yam li cov resin.Lub matrix nws tus kheej thiab qhov chaw sib cuag ntawm cov resin thiab carbon fiber kuj muaj ntau yam ua rau nws.
Yog li ntawd, kev ua haujlwm ntawm qhov nocarbon fiber ntaucov khoom sib txawv heev los ntawm cov resin matrix, thiab nws kuj yuav muaj kev sib txawv hauv ib puag ncig sib txawv thiab cov ntawv thov sib txawv.Piv txwv li, cov khoom siv roj carbon fiber ntau muaj kev ua haujlwm zoo corrosion kuj, thiab tuaj yeem muaj kev ua haujlwm zoo corrosion nyob rau hauv ntau qhov chaw, thiab tag nrho cov huab cua tsis kam yog qhov zoo, tab sis yog tias nws yog nyob rau hauv ib qho chaw kub thiab av noo, piv txwv li. mus rau thaj chaw hauv av, nws yuav muaj hnub nyoog sai dua.Nrog rau kev siv txhua hnub ntawm cov khoom siv roj carbon fiber ntau, nyob rau hauv lub hnub lub rays thiab kev siv dav dav ntawm cov kab hluav taws xob ultraviolet, qhov corrosion feem ntau pib los ntawm qhov chaw corrosion.Thaum peb tsim cov khoom siv fiber ntau longtan, txhawm rau ua kom zoo dua qub corrosion kuj, feem ntau txhais tau hais tias saum npoo yog kho nrog roj thiab coated nrog cov xim pob tshab, uas tuaj yeem ua kom zoo dua corrosion ntawm cov khoom siv fiber ntau.
Txhawm rau kom ntseeg tau zoo dua corrosion ntawm cov khoom siv fiber ntau, cov ntaub ntawv matrix feem ntau yog xaiv cov resins nrog cov qauv macromolecular uas muaj cov qauv ntawm lub cev, benzene rings, thiab heterocycles, thiab hydrogen qab zib crystalline polymers tuaj yeem tsim ntawm cov molecules.Lub matrix yog ib qho kev xaiv zoo rau kev txhim kho corrosion kuj ntawm cov khoom siv fiber ntau.Hauv kev siv cov tswv yim, kev sib txuas ntawm cov resin thiab carbon fiber kuj yog ib qho tseem ceeb uas cuam tshuam rau corrosion, yog li cov txheej txheem ntawm cov khoom siv fiber ntau tuaj yeem txhim kho corrosion kuj zoo thiab zam kev cuam tshuam ntawm ya raws lossis kev tsim teeb meem.
Tsis tas li ntawd, thaum lub sij hawm tsim cov khoom siv carbon fiber ntau, peb kuj xyuam xim rau lawv cov porosity los yog cov yam ntxwv tsis xws luag, nrog rau kev kho compaction, uas tuaj yeem ua rau kev nkag mus ntawm cov tshuaj tiv thaiv corrosion muaj xws li diffusion, uas kuj yog ib qho tseem ceeb rau kev kho mob rau peb cov tuam txhab los txhim kho cov khoom. corrosion kuj ntawm cov khoom siv fiber ntau.Txoj kev.
Nyob rau hauv tag nrho, lub corrosion kuj ntawmcarbon fiber ntauyog zoo heev.Tom qab ntawd kuv hais tias tag nrho corrosion kuj ntawm cov khoom fiber ntau muaj feem xyuam rau cov khoom siv hauv paus nrog rau cov khoom siv tiag tiag thiab kev ua haujlwm.Yog tias muaj qhov yuav tsum tau ua rau corrosion kuj ntawm cov khoom siv fiber ntau, Nws yog ib qho tsim nyog yuav tsum nrhiav cov khoom lag luam zoo carbon fiber ntau cov tuam txhab, kom zoo dua kom ntseeg tau cov kev xav tau ntawm cov khoom siv fiber ntau.
