Carbon fiber raj puag thiab tsis alkali

- Aug 03, 2015 -

Ntau yam kev faib tawm txoj kev leeg carbon fiber ntau. Los ntawm cov khoom xyaw nqaij, lub taub ntsiabteeb, fiber ntau zog, ntau lawm txoj kev thiab khoom kev faib tawm. Uas muaj khoom raw iav, tam sim no rau cov qauv uas nyiam tuaj, mas siv rau ntawm iav nruam fibers. Hlau alkali oxide kawm kom paub qhov txawv txawv alkali hlau oxides feem ntau zej sodium oxide, potassium oxide, sodium carbonate, Glauber's ntsev, feldspar thiab lwm yam mob. Hlau alkali oxide yog ib lub Cheebtsam lub ntsiab ntawm cov iav zoo tib yam, cov nyhuv loj los yog txo lub melting cheej nyob ntawm iav. Tab sis ntau dua cov ntsiab lus ntawm alkali hlau oxides nyob rau hauv lub khob, cov tshuaj stability, hluav taws xob rwb thaiv tsev thiab lub zog yuav raug txo kom haum. Vim li no, qhov sib txawv siv cov iav fiber ntau, khob muaj pes tsawg leeg nrog cov ntsiab lus txawv alkali. Twg alkali ntsiab lus cov ntsiab lus fibre iav siv, raws li ib qho kom paub qhov txawv ntawm nyias siv nruam iav fiber ntau. Raws li lub khob muaj pes tsawg leeg cov ntsiab lus alkali, fibers nruam yuav tau muab faib ua cov pawg nram qab no: e-fibers (feem ntau hu ua e-iav): R2O kawm dua 0.8%: yog ib hom aluminium boron silicate of Written composition. Cov tshuaj stability, rwb thaiv tsev hluav taws xob, yog ua tau zoo heev.

C-fibers (iav c): R20-11.9%-16.4%, yog ib tug dej qab-txiv qaub-silicate muaj pes tsawg leeg, vim nws siab alkali ntsiab lus yuav tsis muab qhia rau hauv hluav taws xob ntaub ntawv insulating, tiam sis cov tshuaj stability thiab ua tau nws zoo.

Alkalinity muaj fiber ntau: R2O iav Cheebtsam ntawm cov ntaub ntawv kawm sib npaug los yog ntau tshaj 15%. Siv daim iav tiaj tus, tu nrho fwj iav ua raw ntaub ntawv twv ntawm. Tam sim no lub teb chaws muaj banned ntau lawm cov khoom uas zoo li no.
