Raws li ib qho tseem ceeb inorganic tsis- nws yog xim hlau cov khoom, zoo tib yam silica micropeable lub luag haujlwm hauv kev lag luam me me. Nws qhov tseem ceeb yog silicon dioxide (sitio₂), uas muaj cov tshuaj siab ntau, cov khoom siv hluav taws xob ruaj khov, thiab cov khoom siv lub cev zoo heev. Nws yog dav siv nyob rau hauv txheej txheej, plastics, roj hmab, ntim ntim, ceramics, thiab lwm thaj teb.
Ua ntej, dog dig silica micropowder cov khoom pov thawj ua tau zoo heev - kub kuj. Vim tias nws tseem tseem ceeb yog silicon dioxide, nrog lub taw tes melting tshaj 1700℃{{} {- kub txheej txheem. Nyob rau hauv high {- tej kev mob kub, silica micropowder tuaj yeem txhim kho lub thermal poob siab thiab thermal ruaj ntawm cov ntaub ntawv, txuas ntxiv lawv txoj kev pabcuam lub neej.
Thib ob, silica micropowder cov khoom pov tseg zoo heev zoo sau thiab txaus ntws. Nws cov khoom zoo thiab cov uniform particle loj faib cov voids nyob rau hauv cov ntaub ntawv, nce ntom ntom ntom ntom ntom ntom nti thiab hnav tsis kam. Hauv cov ntaub ntawv polymer xws li plastics thiab roj hmab ntxiv, ntxiv rau kev cuam tshuam nyuaj thiab cuam tshuam tawm tab sis kuj txo cov nqi tsim khoom thiab txhim kho kev ua tau zoo. Tsis tas li ntawd, txheej li ib ce silica hmoov ua pov thawj zoo rwb thaiv tsev thiab tshuaj ruaj khov. Hauv cov ntaub ntawv ntim ntim ntim hauv hluav taws xob, cov hmoov silica, uas yog ua kom cov coeffricient ntawm cov khoom siv hluav taws xob, thiab txhim kho kev ntseeg tau thiab muaj kev ruaj ntseg ntawm cov hluav taws xob. Tsis tas li ntawd, nws yog insoluble hauv dej, ruaj khov, thiab tsis yog {5}---} {5} - Nws haum rau siv ntau yam kev ua haujlwm ib puag ncig.
Hauv cov ntsiab lus, zoo tib yam silica hmoov, nrog nws cov siab purity, siab {} Cov khoom siv kub, thiab tshuaj lom neeg tseem ceeb thoob plaws ntau yam kev lag luam. Nrog kev nce qib nruam ntawm cov ntaub ntawv txuj ci, kev lag luam xav tau rau Silica Hmoov yuav txuas ntxiv mus, thiab nws qhov tseem ceeb yuav nce ntxiv.
