Yuav ua li cas ua tiav kom qhuav ntawmprecipitated silica? Txheej txheem yog dab tsi?

Silicon Dioxide yog cov enzyme yooj yim adsorbent raw cov ntaub ntawv raw, thiab cov tshuaj lom neeg yog Msio2 · nhh2o. Tsis muaj piam thiab txhua cov kuab tshuaj organic, tsis yog - paab, tsw, thiab muaj zog ruaj khov lub cev. Nws tsis hnov ​​qab hau nrog cov tshuaj lom neeg tshwj tsis yog cov kua qaub muaj zog thiab hydrochloric acid. Yuav ua li cas tuaj yeem ua haujlwm silica ua tau kom qhuav? Txheej txheem yog dab tsi?

Precipitated silica

Qhuav thiab chim siab txog cov nyhuv ntawm cov txiaj ntsig ua kua rau hauv cov dej hauv cov pa roj hmab kom "loj hlob" ntxiv, ua tiav lub hom phiaj kev laus. Txhawm rau kom tau zoo dua kev txhim kho theem, cov khoom lag luam ntawm silica cov khoom siv ntau dua feem ntau hloov kho cov ntsiab lus cov kua roj hauv cov khoom siv roj hmab thaum ziab. Hauv lub neej tswv yim, loj thiab me me pore cov nplaum feem ntau siv nyob rau hauv cov qauv kub feem ntau. Qhov siab dua qhov ziab kom qhuav, ntau dua tus nqi thiab txoj kab uas hla ntawm thawj qhov kev sib sau ua ke ntawm 7 {. Nov yog lub ntsiab ntawm lub ntsiab ntawm kev cais drilling. Txhawm rau tsim Silica gel nrog me me lossis txawm tias tsis yog qhov tsis muaj pore hydrocarbons, nws feem ntau siv los txo cov quab yuam ntawm cov kua.

Cov kev sib txheeb ntawm cov ntsiab lus tseem ceeb ntawm cov roj hmab ua tiav ntawm cov roj hmab ua tiav thiab cov yam ntxwv ua kom tiav cov ntsiab lus tseem ceeb ntawm roj hmab zoo. Ntawm qhov tsis sib xws, qhov ntsuas qhov tseem ceeb ntawm cov roj hmab tiav ntawm cov roj hmab zoo tseem qhia qee yam cov yam ntxwv rau kev ntxias. Cia peb coj lub ntom ntom ntawm cov roj hmab tiav raws li ib qho piv txwv los tshawb xyuas qhov sib thooj ntawm lawv. Kev ceev ntom yog ib qho tseem ceeb tsis zoo nyob rau hauv kev tsom xam cov khoom lag luam silicone tiav, uas muaj kev pom zoo ntawm lub cev nqaij daim tawv ntawm cov txheej txheem huab tais ntawm silicone hais.

Raws li tib qho kev mob, thaum ib qho muaj qee yam pel ntim ntawm silica gel yog sib xws, T3, thiab C Hom ntawm cov nplaum nplaum maj mam nce, thaum VU} maj txo. Nov yog lub hauv paus rau qhov ntom ntom kom dhau los ua qhov sib txawv ntawm a, T3, thiab C Hom cov nplaum. Txawm hais tias tib yam nplaum, qhov loj me ntawm qhov ntom ntom yuav ntxhib dua qhov txawv ntawm cov qauv poj niam sab hauv silica gel hais.

Qhov saum toj no yog kev taw qhia rau tag nrho cov txheej txheem ntawm kom qhuav precipitated silica. Peb ntseeg tias nws yuav pab tau txhua tus. Yog tias koj xav paub cov ntaub ntawv xov xwm ntau ntxiv, koj tuaj yeem mus saib peb lub vev xaib lossis hu rau peb sab laj. Peb yuav zoo siab pab koj.
