Kev faib tawm ntawm cov khoom siv iav fiber ntau

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 ntaub ntawv tseem ceeb rau kev tsim cov iav fiber ntau yog: quartz xuab zeb, alumina, 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 fibers los ntawm molten iav; 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 rov ua kom ntau yam los ua rau hauv lub khob iav los yog pas nrig nrog txoj kab uas hla ntawm 3 - 80μm.
