Bentonite yog cov ntxhia uas tsis yog xim hlau feem ntau yog tsim los ntawm montmorillonite.Cov qauv montmorillonite yog 2: 1 hom siv lead ua qauv tsim los ntawm ob lub silica tetrahedra sandwiched nrog ib txheej ntawm txhuas oxide octahedra.Vim yog cov txheej txheem txheej tsim los ntawm montmorillonite siv lead ua hlwb, muaj qee yam cations, xws li Cu, Mg, Na, K, thiab lwm yam, thiab lawv cov kev cuam tshuam nrog montmorillonite siv lead ua hlwb tsis ruaj khov, uas yooj yim rau kev sib pauv los ntawm lwm cov cations, yog li lawv muaj zoo ion pauv khoom.Txawv teb chaws, nws tau siv nyob rau hauv ntau tshaj 100 departments nyob rau hauv 24 teb ntawm industrial thiab ua liaj ua teb ntau lawm, nrog ntau tshaj 300 khoom, li no tib neeg hu nws "universal av".

Bentonite tseem hu ua bentonite, bentonite, lossis bentonite.Tuam Tshoj muaj keeb kwm ntev ntawm kev tsim thiab siv bentonite, uas yog Ameslikas tsuas yog siv los ua tshuaj ntxuav tes.Muaj cov mines qhib hauv cheeb tsam Renshou ntawm Sichuan ntau pua xyoo dhau los, thiab cov neeg hauv zos hu ua bentonite li av nplaum hmoov.Nws yog dav siv tiag tiag tab sis tsuas yog muaj keeb kwm dhau ib puas xyoo.Qhov kev tshawb pom ntxov tshaj plaws nyob rau hauv Tebchaws Meskas yog nyob rau hauv lub qub strata ntawm Wyoming, qhov twg daj ntsuab av nplaum, uas yuav nthuav mus rau hauv ib tug muab tshuaj txhuam tom qab ntxiv dej, feem ntau hu ua bentonite.Qhov tseeb, cov ntxhia tseem ceeb ntawm bentonite yog montmorillonite, nrog rau cov ntsiab lus ntawm 85-90%.Qee cov khoom ntawm bentonite kuj tau txiav txim los ntawm montmorillonite.Montmorillonite tuaj yeem tshwm sim ntau yam xim xws li daj ntsuab, daj dawb, grey, dawb, thiab lwm yam.Nws tuaj yeem tsim cov blocks ntom ntom lossis xoob av, nrog kev xav zoo nkauj thaum rub nrog ntiv tes.Tom qab ntxiv dej, qhov ntim ntawm cov blocks me me nthuav tawm ob peb zaug mus rau 20-30 zaug, tshwm nyob rau hauv lub xeev tshem tawm hauv dej, thiab hauv lub xeev muab tshuaj txhuam thaum muaj dej tsawg.Cov khoom ntawm montmorillonite muaj feem xyuam rau nws cov tshuaj muaj pes tsawg leeg thiab cov qauv sab hauv.

Activated av nplaum

Activated av nplaum yog ib qho adsorbent ua los ntawm cov av nplaum (feem ntau yog bentonite) ua raw khoom, uas yog raug rau inorganic acidification kev kho mob, ua raws li los ntawm dej yaug thiab ziab.Nws cov tsos yog milky dawb hmoov, tsw ntxhiab, tasteless, non-toxic, thiab muaj zog adsorption kev ua tau zoo.Nws tuaj yeem nqus cov xim thiab cov organic.Nws yog ib qho yooj yim kom nqus noo noo nyob rau hauv cov huab cua, thiab tso nws ntev dhau lawm yuav txo cov adsorption kev ua tau zoo.Txawm li cas los xij, cua sov kom siab tshaj 300 degrees Celsius pib poob dej crystalline, ua rau muaj kev hloov pauv thiab cuam tshuam rau cov nyhuv fading.Activated av nplaum yog insoluble nyob rau hauv dej, organic solvents, thiab ntau yam roj, yuav luag tag soluble nyob rau hauv kub caustic soda thiab hydrochloric acid, nrog ib tug txheeb ze ntom ntawm 2.3-2.5, thiab tsawg o nyob rau hauv dej thiab roj.

Ntuj bleached av

Cov av nplaum uas tshwm sim ib txwm muaj nrog cov khoom siv tshuaj dawb huv yog cov av nplaum dawb, dawb grey feem ntau yog tsim los ntawm montmorillonite, albite, thiab quartz, thiab yog hom bentonite.
Feem ntau cov khoom ntawm decomposition ntawm glassy volcanic pob zeb, uas tsis nthuav tom qab absorbing dej, thiab pH tus nqi ntawm kev ncua yog txawv ntawm alkaline bentonite;Nws cov bleaching kev ua tau zoo yog phem dua li cov av nplaum activated.Cov xim feem ntau muaj xws li lub teeb daj, ntsuab dawb, grey, txiv ntseej xim, xim av, mis nyuj dawb, txiv duaj liab, xiav, thiab lwm yam. Muaj tsawg heev dawb huv sawv daws yuav.Qhov ceev 2.7-2.9g / cm3Qhov pom tseeb qhov ntom yog feem ntau qis vim nws qhov porosity.Cov tshuaj muaj pes tsawg leeg zoo ib yam li cov av nplaum zoo tib yam, nrog rau cov tshuaj lom neeg tseem ceeb yog aluminium oxide, silicon dioxide, dej, thiab ib qho me me ntawm hlau, magnesium, calcium, thiab lwm yam. Tsis muaj plasticity, muaj peev xwm adsorption siab.Vim nws cov ntsiab lus siab ntawm hydrous silicic acid, nws yog acidic rau litmus.Cov dej yog yooj yim tawg thiab muaj cov ntsiab lus dej siab.Feem ntau, qhov zoo dua qhov zoo, qhov siab dua lub zog decolorization.

Bentonite ore
Bentonite ore yog cov ntxhia nrog ntau yam siv, thiab nws qhov zoo.
