Classification ntawm iav fibers

Raws li cov duab thiab ntev, iav fiber ntau tuaj yeem muab faib ua fiber ntau txuas ntxiv, ruaj khov ntev fiber ntau thiab iav ntaub plaub; Raws li cov iav muaj pes tsawg leeg, nws tuaj yeem muab faib ua alkali dawb, tshuaj tiv thaiv, siab alkali, nruab nrab alkali, siab zog, siab elastic modulus thiab alkali resistant iav fiber.

Cov iav fiber ntau tau muab faib ua ntau qib raws li muaj pes tsawg leeg, xwm thiab siv. Raws li tus qauv, Qib E iav fiber ntau yog siv dav thiab dav siv hauv cov khoom siv hluav taws xob rwb thaiv tsev; Qib s yog fiber ntau tshwj xeeb. Txawm hais tias cov zis me me, nws tseem ceeb heev. Vim nws muaj lub zog super, nws yog siv rau kev tiv thaiv tub rog, xws li lub thawv tsis muaj phom, thiab lwm yam; Qib C yog cov tshuaj tiv thaiv ntau dua li Qib E thiab siv rau cov roj teeb cais cov phaj thiab cov tshuaj lom neeg lim dej; Class A yog alkaline iav fiber ntau, uas yog siv los tsim kev txhawb zog.

Kev tsim cov iav fiber ntau

Cov ntaub ntawv tseem ceeb rau kev tsim cov iav fiber ntau yog quartz xuab zeb, alumina thiab pyrophyllite, limestone, dolomite, boric acid, dej qab zib tshauv, mirabilite, fluorite, thiab lwm yam. Cov txheej txheem ntau lawm tuaj yeem faib ua ob pawg: ib qho ncaj qha ua molten iav rau hauv. fibers; Ib qho yog ua kom cov iav molten rau hauv lub khob iav los yog pas nrig nrog txoj kab uas hla ntawm 20mm, thiab tom qab ntawd kub thiab remelt nws nyob rau hauv ntau txoj kev los ua nws nrog ib txoj kab uas hla ntawm 3 ~ 80 μ Zoo heev fiber ntau ntawm M. Cov fiber ntau infinite kos los ntawm mechanical drawing los ntawm platinum alloy phaj yog hu ua nruam iav fiber, uas feem ntau hu ua ntev fiber. Discontinuous fibers ua los ntawm cov menyuam los yog cua ntws yog hu ua ntev iav fibers, feem ntau hu ua luv fibers. Qhov zoo, luv luv thiab flocculent fibers ua los ntawm centrifugal quab yuam los yog high-ceev cua khiav yog hu ua iav ntaub plaub. Tom qab ua tiav, iav fiber ntau tuaj yeem ua rau ntau hom khoom, xws li xov paj, twistless roving, tws precursor, ntaub, siv, xav, phaj, raj, thiab lwm yam.
