Raws li cov khoom sib khi thiab cov khoom siv zawv zawg, carbon fiber muaj qhov muaj zog inertia dua li cov ntaub ntawv ib txwm muaj xws li asbestos, lossis fiberglass, thaum ntsib cov kua qaub muaj zog alkaline tshuaj.Tam sim no, nws muaj qhov zoo dua kub ua haujlwm thiab nws tus kheej lubricating, thiab yog siv los ua cov khoom siv sealing siab heev. Txawm li cas los xij, txawm tias yog cov khoom siv high-tech,cov ntaub ntawv carbon fibertseem ntsib qee qhov nyuaj, xws li cov tshuaj tiv thaiv oxidation, cov tshuaj tiv thaiv rau cov hlau thiab hlau oxides ntawm qhov kub thiab txias, interlayer tebchaw.
1. Cov tshuaj tiv thaiv oxidation
Feem ntau, thaum rhuab mus rau 350 degrees nyob rau hauv cov huab cua, cov pa roj carbon fiber pib oxidize maj mam, qhov loj yuav maj mam txo, thiab qhov kev siv ntawm pib poob. Yog li ntawd, qhov qis dua qhov kub hauv cov txheej txheem tsim khoom, qhov siab dua qhov sib xyaw oxidation tsis kam. Raws li qhov tshwm sim, graphite fibers muaj cov tshuaj tiv thaiv antioxidant zoo dua.
Hauvcarbon fiber manufacturing txheej txheem, muaj Na, K, Ca, MG thiab lwm yam hlau ntsiab tau ntxiv, uas txhawb oxidation ntawm carbon fibers, ntxiv ntawm Phosphorus series cov ntaub ntawv yuav zoo tiv thaiv oxidation. Tsis tas li ntawd, oxidizing acids kuj tuaj yeem ua rau qee qhov corrosion ntawm carbon fiber, tshwj xeeb tshaj yog nyob rau hauv qhov kub thiab txias, siab concentrations.
2. Cov tshuaj tiv thaiv hlau lossis hlau oxides ntawm qhov kub thiab txias
Cov pa roj carbon fibers yuav pib cov tshuaj tiv thaiv nrog NA, Li, K, hlau oxide ntawm 400-500 degrees, nrog Fe, AL ntawm 600-800 degrees, nrog Si, silica, titanium dioxide, magnesium oxide, ntawm 1100-1300 degrees. Tab sis nws tsis muaj teeb meem nrog Cu, Zn, Mg, Ag, Hg, Au. Thaum siv los ua cov khoom siv txhawb zog, cov khoom ntawm cov pa roj carbon fiber ntau yuav raug txwv thaum ntsib cov hlau thiab hlau oxides. Yog li ntawd, carbon fiber tsis tuaj yeem siv rau kev txhawb nqa ntawm oxide ceramics.
