Qhov sib txawv tseem ceeb ntawm kaolin thiab bentonite av nplaum yog cov av nplaum kaolin ua los ntawm huab cua ntawm aluminium silicate minerals xws li feldspar whereas bentonite av nplaum daim ntawv los ntawm volcanic tshauv nyob rau hauv lub xub ntiag ntawm dej. Kaolin hais txog cov ntxhia uas nplua nuj nrog kaolinite.
Ob leeg kaolinite thiab bentonite yog hom av nplaum. Thiab, ob qho tib si cov zaub mov no muaj ntau yam kev siv sib txawv, feem ntau hauv kev tsim cov khoom tu tawv nqaij. Tsis tas li ntawd, ob daim ntawv no poob rau hauv qeb ntawm phyllosilicates. Phyllosilicates yog cov ntxhia silicate, uas muaj cov txheej lossis cov ntawv ntawm silicates.
Kaolin Clay yog dab tsi?
Kaolin yog av nplaum uas nplua nuj nrog cov ntxhia hauv kaolinite. Cov ntxhia no yog cov ntxhia hauv kev lag luam vim tias muaj ntau daim ntawv thov ntawm cov pob zeb no hauv ntau qhov kev lag luam. Yog li, cov tshuaj muaj pes tsawg leeg ntawm cov ntxhia no yog Al2Si2O5(OH) 4 Tsis tas li ntawd, nws poob rau hauv qeb ntawm phyllosilicates vim nws muaj cov nplooj ntawv ntawm silicates. Txawm li cas los xij, muaj lwm cov ntawv silicate, uas muaj tetrahedral silica nplooj thiab octahedral nplooj ntawm alumina; ib daim ntawv silica txuas mus rau ib daim ntawv octahedral alumina ntawm cov pa atom.
Daim duab 01: Kaolin Clay
Kaolin muaj lub peev xwm qis qis-o thiab muaj peev xwm pauv cation tsawg. Ntxiv mus, nws yog ib tug mos av nplaum uas yog earthy thiab feem ntau yog dawb. Cov av nplaum no tsim los ntawm huab cua ntawm aluminium silicate minerals xws li feldspar. Feem ntau, peb tuaj yeem pom nws hauv qhov xwm txheej hauv cov xim liab-txiv kab ntxwv lossis xim liab vim muaj cov hlau oxide nrog cov ntxhia. Thaum nws qib kev lag luam, peb tuaj yeem thauj cov kaolin hauv daim ntawv ntawm cov hmoov qhuav, ib nrab qhuav noodle lossis ua kua slurry.
Cov qauv siv lead ua ntawm cov pob zeb no yog triclinic. Cov xim streak ntawm cov ntxhia kuj yog dawb. Thaum xav txog cov qauv kev hloov pauv ntawm cov ntxhia no, nws tuaj yeem dhau mus rau theem hloov pauv raws li kev kho cua sov (ntawm atmospheric siab).
Daim ntawv thov ntawm Kaolin Clay:
- Kom paub meej cov ntawv coated hauv ntawv ntau lawm
- Nyob rau hauv tsim cov ntaub ntawv ntawm gauze (vim nws muaj peev xwm ua rau kom ntshav txhaws)
- Used hauv ceramics
- In the toothpaste production
- Siv hauv tshuaj pleev ib ce thiab hauv cov khoom tu tawv nqaij (los tsim cov tshuaj tiv thaiv tawv nqaij ua tus neeg saib xyuas tawv nqaij
Dab tsi yog Bentonite Clay
Bentonite yog ib daim ntawv ntawm cov ntxhia uas feem ntau muaj montmorillonite. Nws poob rau hauv qeb ntawm phyllosilicates. Ntau precisely, nws yog ib tug absorbent txhuas phyllosilicate av nplaum. Muaj ob peb hom ntawm cov ntxhia no. Peb lub npe rau lawv xav txog cov tshuaj tseem ceeb muaj nyob rau hauv cov ntxhia. Cov ntsiab lus tseem ceeb feem ntau suav nrog cov poov tshuaj, sodium, calcium, txhuas, thiab lwm yam. Tom qab ntawd peb tuaj yeem hu cov ntxhia ua sodium bentonite, potassium bentonite, thiab lwm yam. Txawm li cas los xij, cov ntawv sodium thiab calcium yog cov ntaub ntawv tseem ceeb tshaj plaws rau kev lag luam.
Daim duab 02: Bentonite tsim los ntawm Volcanic Ash
Feem ntau cov pob zeb no tsim los ntawm cov tshauv volcanic. Nws tsim, feem ntau ntawm lub sij hawm, nyob rau hauv lub xub ntiag ntawm dej. Qhov tseem ceeb tshaj, sodium bentonite nthuav dav thaum ntub dej. Nws tuaj yeem nqus dej ntau zaus ntau dua li nws qhov hnyav. Nws muaj cov khoom zoo colloidal. Yog li ntawd, nws yog ib qho tseem ceeb nyob rau hauv drilling av nkos rau roj thiab roj qhov dej. Thaum xav txog calcium bentonite, nws yog ib qho tseem ceeb adsorbent ntawm ions hauv kev daws teeb meem.
Daim ntawv thov ntawm Bentonite Clay:
- rau qhov av nkos
- Raws li cov ntaub ntawv (raws li kev tsim cov xuab zeb hauv cov hlau thiab hlau)
- Siv ua lub tshuab lim dej kom tshem tawm cov ntxhia sib txawv
- Nws yog qhov nqus tau.
- Raws av thaiv dej
Ntxiv rau qhov ntawd, peb tuaj yeem siv cov ntxhia no hauv cov khoom tu tawv nqaij; vim nws tuaj yeem tshem tawm cov co toxins ntawm peb cov tawv nqaij. Nws yog mos; Yog li, peb tuaj yeem siv nws rau hom tawv nqaij thiab. Thaum nws tshem tawm cov co toxins, nws tseem tawm cov zaub mov zoo, uas peb cov tawv nqaij tuaj yeem nqus tau.
Qhov txawv ntawm Kaolin thiab Bentonite Clay yog dab tsi?
Kaolin yog av nplaum uas nplua nuj nrog cov ntxhia hauv kaolinite. Bentonite yog ib hom ntxhia uas feem ntau muaj montmorillonite. Lawv muaj cov qauv tshuaj sib txawv; Cov tshuaj formula ntawm kaolin yog Al2Si2O5(OH) 4 thaum cov tshuaj formula ntawm bentonite sib txawv nrog cov tshuaj tseem ceeb tam sim no hauv av nplaum, piv txwv li sodium bentonite chemical formula yog Al2H2 Na2O13Si4
Ntxiv mus, Kaolin muaj tetrahedral silica nplooj thiab octahedral nplooj ntawm alumina; ib daim ntawv silica txuas mus rau ib daim ntawv octahedral alumina ntawm cov pa atom. Txawm li cas los xij, Bentonite muaj peb txheej txheej txheej txheej txheej uas muaj cov ntawv nruab nrab octahedral alumina thiab ob daim ntawv tetrahedral silica. Raws li qhov sib txawv tseem ceeb ntawm kaolin thiab bentonite av nplaum, peb tuaj yeem coj lawv tsim; Kaolin tsim los ntawm huab cua ntawm aluminium silicate minerals xws li feldspar whereas Bentonite cov ntaub ntawv los ntawm volcanic tshauv nyob rau hauv lub xub ntiag ntawm dej.
Cov duab hauv qab no nthuav tawm qhov sib txawv ntawm kaolin thiab bentonite av nplaum hauv daim ntawv tabular.
Summary – Kaolin vs Bentonite Clay
Kaolin thiab bentonite yog ob hom av nplaum uas nplua nuj nrog txhuas thiab silica minerals. Qhov txawv ntawm kaolin thiab bentonite av nplaum yog tias Kaolin tsim los ntawm huab cua ntawm aluminium silicate minerals xws li feldspar whereas Bentonite cov ntaub ntawv los ntawm volcanic tshauv nyob rau hauv lub xub ntiag ntawm dej.
