Cov tshuaj lom neeg muaj pes tsawg leeg
Ua ntej, peb yuav tsum piav qhia meej tias cov pa roj carbon dawb thiab silicon dioxide muaj cov tshuaj lom neeg zoo ib yam, thiab lawv cov mis tshuaj yog SiO₂. Cov pa roj carbon dawb yog ib daim ntawv tshwj xeeb ntawm silica, thiab nws cov khoom sib xyaw tuaj yeem sawv cev los ntawm SiO2 · nH2O, qhov twg nH2O muaj nyob rau hauv daim ntawv ntawm cov pab pawg hydroxyl saum npoo av.
Cov tsos thiab cov khoom
Hais txog qhov tsos thiab cov khoom, cov pa roj carbon dawb thiab silica kuj txawv. Qhov tsos ntawm silica yog cov hmoov dawb amorphous, tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis muaj kuab paug. Nws cov qauv me me yog spherical, flocculent, thiab zoo li network, tsis yaj hauv dej. Qhov tsos ntawm cov pa roj carbon dawb, ntawm qhov tod tes, yog cov hmoov dawb, granular lossis tsis sib xws, yaj hauv caustic soda thiab hydrofluoric acid, tsis yaj hauv dej, cov kuab tshuaj, thiab cov kua qaub (tsis suav nrog hydrofluoric acid), thiab muaj cov yam ntxwv ntawm kev tiv taus kub siab, tsis kub hnyiab, tsis muaj ntxhiab, tsis muaj ntxhiab, thiab rwb thaiv hluav taws xob zoo.
thaj chaw thov
Hais txog kev siv, cov pa roj carbon dawb thiab silica kuj muaj lawv tus yam ntxwv. Silicon dioxide yog ib yam khoom siv tseem ceeb uas siv dav hauv kev tsim cov iav, iav quartz, sodium silicate, cov fibers optical, cov khoom tseem ceeb ntawm kev lag luam hluav taws xob, cov cuab yeej siv kho qhov muag, cov khoom siv tes ua, thiab cov khoom siv refractory. Cov pa roj carbon dawb siv dav hauv cov khoom siv roj hmab, cov tshuaj ua liaj ua teb, cov khoom siv tshuaj txhua hnub, cov yas, cov tshuaj pleev xim, cov khoom sib xyaw resin, thiab cov ntawv sau. Tsis tas li ntawd, cov pa roj carbon dawb tau siv dav ua cov khoom hloov pauv rau cov pa roj carbon dub hauv cov khoom siv roj hmab.
Txoj kev npaj
Hais txog cov txheej txheem npaj, cov pa roj carbon dawb thiab silica kuj txawv. Cov pa roj carbon dawb tuaj yeem npaj tau los ntawm cov txheej txheem nag lossis cov txheej txheem roj, thiab cov txheej txheem npaj sib txawv ua rau muaj ob yam khoom sib txawv nrog tib cov mis molecular.
Cov yam ntxwv ntawm kev ua tau zoo
Hais txog cov yam ntxwv ntawm kev ua tau zoo, kuj muaj qhov sib txawv ntawm cov pa roj carbon dawb thiab silica. Cov pa roj carbon dawb yog cov khoom porous, nrog rau cov qauv sib sau ua ke thiab cov qauv me me zoo ib yam li cov pa roj carbon dub. Nano silica, ntawm qhov tod tes, yog cov khoom dawb inorganic non-metallic uas tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis muaj kuab paug nrog cov khoom me me (0-100nm) thiab thaj chaw loj. Nws muaj cov yam ntxwv zoo heev rau kev cuam tshuam rau ultraviolet, infrared, thiab lub teeb pom kev. Qhov ntim thiab quantum tunneling ntawm nano silica ua rau nws muaj qhov cuam tshuam percolation, uas tuaj yeem tsim cov qauv network spatial nrog cov organic molecular compounds, txhim kho lub zog kho tshuab, toughness, hnav tsis kam, thiab kev laus tsis kam ntawm cov ntaub ntawv polymer.
Hauv kev xaus, txawm hais tias cov pa roj carbon dub dawb thiab silica muaj cov tshuaj lom neeg zoo ib yam, lawv txawv ntawm qhov tsos, cov khoom, thaj chaw siv, thiab cov txheej txheem npaj.
