Cov Khoom Siv Iav Fiber Uas Tsis Yog Woven

I. Cov yam ntxwv tseem ceeb ntawm cov khoom: Kev sib xyaw ua ke ntawm cov khoom siv thiab cov txiaj ntsig ntawm cov txheej txheem

Kev cia siab rau qhov zoo ntawm kev ua tau zoo ntawm cov iav fiber thiab kev txhawb nqa thev naus laus zis ntawm spunlace thiab cov txheej txheem sib xyaw, ob hom khoom sib txawv tsim cov txheej txheem kev ua tau zoo tshwj xeeb, thiab tib lub sijhawm tawg los ntawm cov kev txwv kev ua tau zoo ntawm ib yam khoom.

(1) Cov ntaub iav fiber tsis-woven: Qhov kev ua tau zoo ntawm cov khoom siv inorganic

Siv cov iav fiber uas tsis muaj alkali ua cov khoom siv raw, nws yog tsim los ntawm kev sib xyaw luv luv thiab kev sib xyaw ua ke ntawm cov dej siab. Thaum khaws cov yam ntxwv tseem ceeb ntawm cov iav fiber, nws kuj muaj cov txiaj ntsig zoo ntawm cov qauv tsis-woven:

Tiv taus kub heev, tsis kub hnyiab thiab rwb thaiv tsev: Lub hauv paus ntawm kev nyab xeeb hauv qhov chaw ib puag ncig hnyav

Kev ua haujlwm ruaj khov ntawm qhov kub thiab txias dav dav: Lub ntsiab lus yaj ntawm cov iav fiber ntau dua 800 ℃, thiab cov khoom tiav tuaj yeem siv tau ntev hauv ib puag ncig ntawm 260 ℃, nrog rau kev tiv thaiv kub luv luv txog li 300 ℃, ntau tshaj qhov txwv tsis pub kub ntawm polyester fiber (kev tiv thaiv kub ≤150 ℃). Nws tsis tas yuav ntxiv cov tshuaj tua hluav taws, nrog rau qhov ntsuas oxygen txwv (LOI) ntawm ≥30%. Nws tsis hlawv lossis yaj thiab ntws thaum raug hluav taws, tsuas yog tswj hwm qhov kev ncaj ncees ntawm cov qauv inorganic fiber. Nws yog cov khoom siv tiv thaiv tseem ceeb rau cov xwm txheej ua haujlwm kub siab.
