Silica hloov tau ib feem ntawm cov ntses noj mov hauv cov ntses thiab prawn pub, kev tshawb fawb los ntawm tus Tub Vaj Ntxwv ntawm Songkla University hauv Thaib teb.

Silica yog dab tsi? Dab tsi yog qhov kev siv ntawm silica?

Los ntawm kev siv cov yam ntxwv tshwj xeeb xws li loj tshwj xeeb ntawm qhov chaw deg, qhov ntxeem tau, kev tawm suab ntawm silica, peb tuaj yeem tsim silica raws antibacterial hmoov nrog kev ua

Cov sealants thiab adhesives yog cov khoom tseem ceeb heev uas tsim nyog los ntawm ntau cov lag luam. Cov ntsiab lus tseem ceeb rau cov khoom no yog: viscosity, fluidity, thiab so

Raws li cov ntaub so ntswg, cov khoom qab zib thiab cov khoom qub, cov tshuaj nplaum los ntawm cov tshuaj nplaum (JS-280) yog siv los pleev xim rau cov tshuaj txhuam hniav thiab cov tshuaj tsis

Ntau dua thiab ntau cov tshuaj tua kab, cov chiv zoo dua lawv cov dej num los ntawm kev muab cov tshuaj ntsev ntau dua rau hauv lawv cov khoom (qhov feem pua ​​qhia ntxiv yog 10%).

Nws noj tau thiab raug txwv. Silicon dioxide yog ib hom tshuaj tiv thaiv kab mob.

Silica yog ib qho dawb amorphous hmoov, nplaum yog unsaturated residues thiab sib txawv hauv tsev ntawm pawg hydroxyl, molecular lub xeev ntawm cov qauv uas muaj peb sab. Feem nta

Thaum silicon khi nrog cov pa oxygen, nws tsim ib lub paj hlwb hu ua silicon dioxide (SiO2). Lwm lub npe rau silicon dioxide yog silica, uas muaj xws li nws ntau cov ntaub ntawv,

Yav tom ntej thov kev loj hlob: tire silicone roj hmab txhuam hniav cov ntaub ntawv pov thawj.
