Cov iav fiber ntau tuaj yeem raug faib ua cov fiber ntau txuas, tsau cov plaub hau ntev thiab iav ntaub plaub raws li nws cov duab thiab ntev. Raws li cov iav muaj pes tsawg leeg, nws tuaj yeem faib ua alkali-dawb, tshuaj lom neeg-tiv taus, siab-alkali, nruab nrab-alkali, siab zog, siab-elasticity thiab alkali-resistant (Alkali resistant) iav fiber, thiab lwm yam.
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, cesardite, fluorite thiab lwm yam. Cov txheej txheem kev tsim tawm yog ntxaib tau muab faib ua ob pawg: ib qho yog ncaj qha tsim cov iav molten mus rau hauv daim txiag; lwm qhov yog ua ntej ua cov iav molten rau hauv lub khob pob lossis pas nrig nrog lub taub 20 mm, thiab tom qab ntawd rov qab rau nws nyob rau ntau txoj hauv kev los ua txoj kab uas hla ntawm 3 ~ Zoo nkauj fiber ntau ntawm 80 μm. Qhov infinitely ntev fiber ntau kos los ntawm kev siv tshuab nqus los ntawm platinum alloy phaj hu ua cov iav txuas ntxiv thiab feem ntau hu ua fiber ntau ntev. Cov hluav taws xob tsis zoo txuas ntxiv los ntawm cov yob lossis cua ntws, hu ua ntev ntev ntawm cov iav fiber ntau, feem ntau hu ua cov xov luv luv.
Cov iav fiber ntau tau muab faib ua cov qib sib txawv raws li kev sib xyaw, yam thiab siv. Raws li cov txheej txheem qib (saib lub rooj), E-qib iav fiber ntau feem ntau siv, dav siv hauv cov khoom siv hluav taws xob rwb thaiv tsev; S qib tshwj xeeb fiber ntau.
