Kaolin yog ib hom av ntawm av nplaum thiab av nplaum pob zeb uas muaj los ntawm cov av nplaum ntau ntawm cov pab pawg kaolinite. Nws yog ib hom kabmob uas tsis yog xim hlau thiab yog lub npe tom qab Gaoling Village, Jingde Town, Jiangxi Xeev. Kaolin tau faib ua cov pob zeb tsis txuas kev tsim kho kaolin thiab coal series kaolin (pob zeb). Tam sim no, feem ntau ntawm cov kaolin tsim nyob rau hauv lub ntiaj teb belongs rau lub qub.
Raws li ib qho tseem ceeb ntxhia raw khoom, kaolin yog dav siv nyob rau hauv ntau lub teb. Hauv kev lag luam ceramic, kaolin feem ntau yog siv los ua cov khoom siv raw ua rau kev ua ntau yam ceramic; hauv kev lag luam refractory thiab xis mas, qib siab dua ntawm kaolin tuaj yeem siv los ua cov iav kho qhov muag, iav fiber crucibles thiab kuaj ntsia hlau ntoo; kaolin nrog qis kev coj dawb huv Nws tuaj yeem siv los ua cov ntaub ntawv zoo li refractory cib thiab av nkos refractory; hauv kev lag luam ntawv, kaolin siv los ua muab tub lim thiab txheej rau ntawv; hauv kev lag luam roj hmab, kaolin siv los ua cov txheej txheem txhawb nqa thiab muab tub lim.
Ntau lub teb daim ntawv thov muaj qhov tshwj xeeb uas yuav tsum tau muaj ntawm kaolin. Txhawm rau kom tau raws li kev thov daim ntawv thov, nws yuav tsum yog hloov kho saum npoo. Kev hloov kho deg yog ib qho tseem ceeb heev ua kev hloov kho txheej txheem ntawm kaolin. Nws yog hais txog kev siv lub cev, tshuaj lom neeg lossis kev kho tshuab ntawm qhov chaw ntawm kaolin raws li cov kev xav tau ntawm daim ntawv thov, thiaj li txhim kho qhov ntsej muag, ci ci, kev ua haujlwm saum npoo lossis txhim kho polymerization ntawm kaolin. Kev sib raug zoo thiab lwm cov hom phiaj.
Hloov saum npoo ntawm kaolin
Muaj feem ntau yog cov hauv qab no rau kev hloov kho ntawm kaolin: calcination, tus neeg sawv cev txuas, adsorption, thiab txheej txheej saum npoo.
Cov kev hloov kho calcium
Calcining hloov kho yog hais txog calcining kaolin ntawm qhov kub kom tshem tawm ib feem lossis tag nrho ntawm pawg hydroxyl nyob rau saum npoo ntawm kaolin kom tau txais cov khoom tshwj xeeb saum npoo, uas ua rau cov qauv siv lead ua ntawm kaolin hloov, los ntawm daim ntawv txiav txim siab siv lead ua qauv ua rau tsis pom kev tsis txaus.
Thaum calcining kaolin, mloog yuav tsum tau them rau xaiv kub. Thaum calcined ntawm qhov kub tsawg dua, qhov kev ua ntawm kaolin muaj ntau dua; thaum calcined ntawm qhov kub tshaj, aluminium spinel tuaj yeem tsim, thiab mullite yuav tsim nyob rau ntawm qhov ntsuas kub. Qhov kev ua no me me thiab tsis tuaj yeem ua raws li qhov xav tau ntawm qee yam khoom siv polymer khoom.
Hloov txheej txheej txheem txheej txheem kev hloov kho
Cov txheej txheej saum npoo av siv cov tshuaj adsorption lossis tshuaj pleev tso tawm rau txheej txheej ntawm cov organic nyob saum npoo ntawm kaolin kom ua tiav lub hom phiaj kev hloov kho Cov qauv siv dav dav yog stearic acid, glyceryl trimethacrylate, trimethoxypropane triglycidyl ether, tsis tshua muaj molecular polyethylene ciab thiab lwm yam.
Qhov kom zoo dua ntawm cov qauv no yog tias tom qab kaolin hloov kho, qhov kev ruaj ntseg ntawm cov khoom qauv thiab cov haujlwm catalyst tuaj yeem ua kom zoo dua, cov neeg cov hmoov sib xyaw ua kom tsis muaj zog, thiab cov dispersion thiab fluidity tau zoo dua.
Ob peb tus neeg sawv cev hloov kho
Kev sib koom tus neeg sawv cev siv txoj kev sib cuam tshuam ntawm cov pab pawg nquag nyob rau saum npoo ntawm kaolin thiab tus neeg sawv cev txuas mus kom tau lub hom phiaj ntawm kev hloov pauv thaj chaw thaj av ntawm kaolin. Kev sib koom tes rau tus neeg sawv cev feem ntau muaj ob txoj kev kho: kev kho kom sov thiab kho kom qhuav. Kev ntub dej yog ua kom yaum cov kaolin hmoov hauv kev daws nrog tus neeg sawv cev txuas, ua raws li qhov ntsuas kub, thiab cais cov kuab tshuaj los ntawm cov kaolin hmoov, thiab tom qab ntawd cov hmoov qhuav. Piv nrog rau kev ua qhuav, kev ua ntub dej muaj qhov zoo ntawm kev sib xyaw ua ke ntawm cov hmoov thiab txuas tus neeg sawv cev, tab sis kev ua ntub dej muaj ntau cov tshuab ua cov txheej txheem ntau, cov kuab tshuaj loj thiab cov nqi siab.
Kev ua kom qhuav yog muab cov kaolin hmoov tso rau hauv kev kub ceev cov khoom sib tov, do thiab qhuav ntawm qhov kub, maj mam ntxiv cov kuab tshuaj thiab tus neeg sawv cev hauv lub npov txuas rau tus neeg sawv cev txuas, thiab tom qab ib lub sijhawm ntawm nplawm kho, nws tuaj yeem npaj Mus nto nto hloov kaolin muab tub lim.
Kev hloov kho los ntawm kev sib tos
Cov txheej txheem sib hloov sib xyaw siv cov kev sib zog ua kom tsis muaj zog ntawm cov khaubncaws sab nraud povtseg ntawm txheej txheej hmoov txheej txheej hmoov txheej txheej lossis txheej txheem sib xyaw muaj cov ntawv sib pauv hloov tau, thiab siv tshuaj lom neeg lossis kev sib pauv ntawm cov ion pauv txoj hauv kev los hloov cov interlayer thiab interface lub zog ntawm cov hmoov.
Ua kua-theem intercalation txuj kev siv ntau hom kev hloov kho ntawm kaolin intercalation kev hloov kho, thiab nws cov ntawv thov ntau yog dav. Cov tshuaj tiv thaiv ntawm intercalant hauv emulsion lossis kev daws teeb meem yog ib qho kev qhia ntawm cov kua theem sib cais txoj kev.
Cov txheej txheem evaporation solvent intercalation yog hom kua theem sib cais, thiab nws lub ntsiab lus yog: ua ntej cov roj me me ziab kom ua kom cov kuab tshuaj kom tiav cov tshuaj lom thiab sib tov, thiab tom qab ntawd nkag mus rau kaolin interlayer kom txuas ntxiv cov txheej txheem sib xyaw.
Lub hauv paus ntsiab lus ntawm mechanochemical intercalation txoj kev yog tias lub zog cov neeg kho tshuab siv rau tus neeg sawv cev sib cuam tshuam los ntawm kev ua ntawm cov tshuab kev sib tsoo, nplawm, shearing thiab nqus pom kom ntxias lub cev lossis tshuaj lom neeg, thiab tom qab ntawd kev sib cuam tshuam ntawm kaolin thiab intercalation tus neeg sawv cev txhawb qhov kev ua tiav du. ntawm kaolin kev hloov kho kev hloov pauv.
Xaus
Pib ntawm lub xyoo pua 21st, kev lag luam organic polymer khoom lag luam tau nkag mus rau theem ntawm kev hloov pauv ntawm kev lag luam thiab qhib. Kev hloov los ntawm ntau hom kev xaiv mus rau qhov ua tau zoo, ntau yam thiab cov txiaj ntsig kev txhawb kev lag luam kom tau lub hom phiaj ntawm kev lag luam qhib.
Vim li no, kev lag luam kaolin yuav tsum tau fim qhov tseeb. Nws yuav tsum tsom rau kev txhim kho kev coj ntawm cov organic polymer cov khoom lag luam kev lag luam thiab sib koom ua ke nrog cov thev naus laus zis ntawm nws cov khoom, kom qhov kev hloov kho saum npoo ntawm kaolin yuav tsum muaj cov khoom lag luam zoo, cov khoom lag luam zoo, tsim txiaj ntsig thiab ntau yam ua haujlwm Cov. Kev sib deev hloov kho txhim kho qhov kev hloov kho saum npoo ntawm calcined kaolin rau qib siab.
