Qhov sib txawv tseem ceeb ntawm kaolinite thiab montmorillonite yog tias kaolinite muaj ib daim ntawv txhuas octahedral thiab ib daim ntawv silica tetrahedral whereas montmorillonite ntxhia muaj ob daim ntawv silica tetrahedral thiab ib daim ntawv txhuas octahedral ib chav tsev rov ua dua.
Kaolinite thiab montmorillonite yog av nplaum ntxhia. Cov zaub mov no muaj lawv cov qauv tshuaj raws li cov nplooj ntawv sib sau ua ke hauv qhov sib txawv.
Kaolinite yog dab tsi?
Kaolinite yog ib hom av nplaum ntxhia uas muaj tshuaj lom neeg Al 2SiO2O5 (OH)4 Nws yog ib pab pawg ntawm cov zaub mov uas tshwm sim raws li txheej txheej silicate ntxhia nrog ib daim ntawv tetrahedral ntawm silica uas txuas los ntawm oxygen atoms mus rau lwm daim ntawv octahedral ntawm alumina. Feem ntau, lo lus kaolin yog siv los hais txog cov pob zeb uas nplua nuj nyob hauv kaolinite. Tuam Tshoj av nplaum yog lwm lub npe rau hom pob zeb no.
Cov qeb ntawm kaolinite yog phyllosilicates, thiab cov khoom siv no muaj lub cev siv lead ua triclinic. Nws tshwm nyob rau hauv dawb mus rau cream xim, tab sis tej zaum peb yuav saib liab, xim av los yog xiav tints uas yog los ntawm lub xub ntiag ntawm impurities. Ntxiv mus, nws tsis tshua muaj tshwm sim raws li muaju, tab sis nws yog feem ntau nyob rau hauv ib lub phaj zoo li cov qauv uas yog stacked los tsim tag nrho cov qauv. Cov pob zeb no muaj pearly luster thiab cov ntxhia streak yog dawb.
Kaolinite muaj ntau yam khoom tseem ceeb, xws li qis qis o muaj peev xwm thiab tsis tshua muaj peev xwm pauv cation. Tsis tas li ntawd, cov ntxhia no yog cov pob zeb mos, hauv av uas feem ntau yog xim dawb. Kaolinite yog tsim los ntawm huab cua ntawm aluminium silicate minerals xws li feldspar.
Muaj ntau ntau yam kev siv kaolinite ntxhia xws li kev tsim cov ntawv, ceramics, tshuaj txhuam hniav, tshuaj pleev ib ce, tsim cov ntaub ntawv insulating xws li kaowool, xim, rau kev hloov kho cov khoom ntawm roj hmab raws li vulcanization, hauv organic ua liaj ua teb li. tshuaj tsuag, thiab lwm yam.
Montmorillonite yog dab tsi?
Montmorillonite yog hom av nplaum uas muaj cov qauv dav dav (Na, Ca) 0.33(Al, Mg) 2(Si4O10)(OH)2nH2 O. Cov ntxhia no belongs rau pawg phyllosilicates. Cov txheej txheem siv lead ua ntawm cov khoom siv no yog monoclinic, thiab cov tsos tuaj yeem piav qhia raws li dawb, daj ntseg liab rau xim liab. Qhov tawg ntawm cov ntxhia no tsis sib xws. Cov luster yog npub thiab earthy. Thaum xav txog cov qauv tshuaj, cov khoom no muaj ob daim ntawv tetrahedral ntawm silica, sandwiching lub hauv paus octahedral ntawv ntawm alumina.
Muaj kev siv ntau yam ntawm montmorillonite. Nws yog siv nyob rau hauv kev lag luam dilling ua ib feem ntawm cov av nkos drilling uas pab ua kom cov av slurry khov. Tsis tas li ntawd, cov khoom siv no muaj txiaj ntsig zoo li cov av ntxiv los tuav cov dej hauv av hauv cov av uas muaj kev kub ntxhov. Cov ntxhia no muaj txiaj ntsig zoo hauv cov txheej txheem catalytic xws li catalytic cracking. Ntxiv rau qhov ntawd, montmorillonite muaj cov khoom siv o uas ua rau nws tseem ceeb xws li lub foob pob hluav taws lossis ntsaws rau cov dej hauv dej thiab ua ib qho kev tiv thaiv rau kev pov tseg.
Qhov txawv ntawm Kaolinite thiab Montmorillonite yog dab tsi?
Kaolinite thiab montmorillonite yog av nplaum ntxhia. Cov zaub mov no muaj lawv cov qauv tshuaj raws li cov nplooj ntawv sib dhos rau ib leeg hauv qhov sib txawv. Qhov sib txawv tseem ceeb ntawm kaolinite thiab montmorillonite yog tias kaolinite muaj ib daim ntawv txhuas octahedral thiab ib daim ntawv silica tetrahedral whereas montmorillonite ntxhia muaj ob daim ntawv silica tetrahedral thiab ib daim ntawv txhuas octahedral ib chav tsev.
Ntxiv mus, kaolinite feem ntau yog dawb rau cov xim pleev xim thaum montmorillonite yog dawb, daj ntseg liab rau xim liab.
Hauv qab infographic qhia ntau qhov sib txawv ntawm kaolinite thiab montmorillonite.
Summary – Kaolinite vs Montmorillonite
Kaolinite thiab montmorillonite yog av nplaum ntxhia. Cov zaub mov no muaj lawv cov qauv tshuaj raws li cov nplooj ntawv sib dhos rau ib leeg hauv qhov sib txawv. Qhov sib txawv tseem ceeb ntawm kaolinite thiab montmorillonite yog tias kaolinite muaj ib daim ntawv txhuas octahedral thiab ib daim ntawv silica tetrahedral whereas montmorillonite ntxhia muaj ob daim ntawv silica tetrahedral thiab ib daim ntawv txhuas octahedral ib chav tsev.
