tuaj yeem carbon fiber hlawv
1. Muaj pes tsawg leeg thiab cov yam ntxwv ntawm carbon fiber
Cov pa roj carbon fiber ntau yog tsim los ntawm cov ntsiab lus carbon thiab muaj ntau yam zoo heev xws li lub zog siab, tsis tshua muaj siab thiab kub tsis kam. Nws feem ntau yog ua los ntawm cov organic fiber ntau los ntawm kev kho tshuaj lom neeg thiab cov txheej txheem carbonization siab. Piv txwv li, feem ntau polyacrylonitrile (PAN)-raws li carbon fiber, nws cov precursor yog hloov mus rau carbon fiber nrog siab carbon ntsiab lus tom qab ntau yam txheej txheem xws li pre-oxidation thiab carbonization.
2. Combustion ntawm carbon fiber
1. Cov xwm txheej dav dav
- Nyob rau hauv ib txwm muaj, carbon fiber muaj cov nplaim hluav taws zoo. Vim nws cov ntsiab lus carbon siab thiab cov qauv tshwj xeeb, nws tsis yooj yim rau hlawv li cov organic fibers. Qhov no ua rau cov pa roj carbon fiber ntau siv tau rau hauv ntau qhov chaw nrog qee qhov kev xav tau rau kev tiv thaiv hluav taws, xws li aerospace teb. Cov khoom siv carbon fiber ntau yog siv hauv qee qhov ntawm cov dav hlau. Thaum ntsib qhov kub thiab txias ib puag ncig los yog hluav taws kub, carbon fiber muaj peev xwm tswj tau cov qauv kev ncaj ncees rau qee lub sijhawm, muab kev ruaj ntseg.
2. Qhov xwm txheej tshwj xeeb
- Txawm li cas los xij, yog tias carbon fiber tau muab tso rau hauv qhov kub thiab txias txaus, nws tuaj yeem hlawv. Piv txwv li, thaum kub siab tshaj nws qhov tseem ceeb combustion kub (qhov kub no txawv nyob ntawm seb hom tshwj xeeb, qauv thiab ib puag ncig ib puag ncig ntawm cov pa roj carbon fiber), thiab muaj cov pa oxygen txaus, cov pa roj carbon fiber yuav dhau los ua cov tshuaj tiv thaiv oxidation thiab hlawv. Hauv qee qhov xwm txheej hluav taws kub heev, cov pa roj carbon fiber ntau hauv cov qauv carbon fiber ntau yuav raug hlawv.
- Tsis tas li ntawd, yog tias cov pa roj carbon fiber ntau sib xyaw nrog qee yam khoom siv hluav taws xob yooj yim lossis tuaj yeem tiv nrog cov khoom tshwj xeeb xws li cov oxidants muaj zog, nws cov khoom siv hluav taws xob kuj tuaj yeem hloov pauv, ua kom yooj yim hlawv.
III. Kev tshawb nrhiav thiab kev tiv thaiv muaj feem xyuam rau carbon fiber combustion
1. Kev tshawb fawb qhia
- Cov kws tshawb fawb tau kawm txog combustion mechanism ntawm carbon fiber, sim ua kom nkag siab zoo txog kev sib txuas ntawm cov pa roj carbon fiber ntau hauv cov xwm txheej sib txawv. Qhov no suav nrog kev kawm txog tus nqi combustion thiab combustion khoom ntawm carbon fiber nyob rau hauv txawv ib puag ncig yam xws li kub, av noo, thiab oxygen concentration. Los ntawm cov kev tshawb fawb no, lub hauv paus theoretical tuaj yeem muab rau kev ntsuam xyuas kev nyab xeeb ntawm carbon fiber hauv ntau yam kev thov.
2. Kev tiv thaiv
- Hauv kev siv cov tswv yim, txhawm rau tiv thaiv cov kev pheej hmoo los ntawm carbon fiber combustion, qee qhov kev kho tshwj xeeb feem ntau ua rau carbon fiber. Piv txwv li, thaum tsim cov carbon fiber composites, nplaim retardants yog ntxiv los txhim kho lawv tag nrho cov nplaim retardant zog. Nyob rau tib lub sijhawm, thaum tsim cov qauv siv cov pa roj carbon fiber ntau, cov kev tiv thaiv hluav taws kuj tseem yuav raug txiav txim siab, thiab cov txheej txheem hluav taws xob sib cais lossis cov cuab yeej tiv thaiv hluav taws yuav raug teeb tsa kom ntseeg tau tias thaum muaj hluav taws kub, cov teeb meem tshwm sim los ntawm kev kub hnyiab. ntawm carbon fiber tuaj yeem txo qis.
