Njengesixhobo sokutywina kunye ne-sliding material, i-carbon fiber ine-inertia enamandla kunezinto zendabuko ezifana ne-asbestos, okanye i-fiberglass, xa idibana ne-asidi eqinile kakhulu kwizinto ze-alkaline.Ngexesha elifanayo, inokumelana nokushisa okungcono kunye nokuzithambisa, kwaye isetyenziswe njengento yokutywina ephambili. Nangona kunjalo, nangona njengesixhobo sobuchwepheshe obuphezulu,izixhobo carbon fibersisajongene nobunzima, obufana ne-oxidation reaction, ukusabela kwisinyithi kunye neeoksidi zetsimbi kumaqondo obushushu aphezulu, iikhompawundi ze-interlayer.
1. Ukusabela kwe-oxidation
Ngokuqhelekileyo, xa ukufudumala ukuya kuma-degrees angama-350 emoyeni, i-carbon fiber iqala ukuxutywa ngokukhawuleza, ubunzima buyancipha kancane kancane, kwaye ukuqina buqala ukuhla. Ke ngoko, iqondo eliphantsi lobushushu kwinkqubo yokuvelisa, kokukhona liphezulu ukumelana ne-oxidation ehambelanayo. Ngenxa yoko, iifiber zegraphite zinokuchasana okungcono kakhulu kwe-antioxidant.
Kwiinkqubo yokwenza i-carbon fiber, kukho i-Na, K, Ca, MG kunye nezinye izinto zetsimbi zongezwa, ezikhuthaza i-oxidation ye-carbon fibers, ukongezwa kwe-Phosphorus series materials inokuthintela ngokufanelekileyo i-oxidation. Ukongezelela, i-asidi ene-oxidizing nayo inokubangela umlinganiselo othile we-corrosion kwi-carbon fiber, ngokukodwa kwiqondo lokushisa eliphezulu, ukugxila okuphezulu.
2. Ukusabela ngesinyithi okanye i-oxide yensimbi kumaqondo aphezulu okushisa
Iifayibha zeCarbon ziya kuqalisa ukuphendula kweekhemikhali kunye ne-NA, i-Li, K, i-iron oxide kwi-400-500 degrees, kunye ne-Fe, AL kwi-600-800 degrees, kunye ne-Si, i-silica, i-titanium dioxide, i-magnesium oxide, kwi-1100-1300 degrees. Kodwa ayinamsebenzi neCu,Zn,Mg,Ag,Hg,Au. Xa isetyenziswe njengezinto zokuqinisa, iipropati ze-carbon fiber ziya kunqunyulwa kakhulu xa zidibana neentsimbi kunye nee-oxide zetsimbi. Ngoko ke, i-carbon fiber ayinakusetyenziselwa ukuqinisa i-oxide ceramics.
