Hmoov Kaolin yog cov pob zeb uas tsis yog hlau uas tshwm sim los ntawm ntuj tsim, uas muaj kaolinite ua tus thawj coj, muaj cov qauv mos mos, qhov loj me me thiab cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg. Cov yam ntxwv tseem ceeb suav nrog kev dawb huv, kev ua kom zoo heev, kev ruaj khov ntawm cov tshuaj lom neeg thiab kev muaj peev xwm ncua tau zoo - cov yam ntxwv uas ua rau nws tsis tseem ceeb hauv cov qauv kev lag luam tshwj xeeb. Tsis zoo li cov pob zeb uas txwv rau cov ntawv thov nqaim, hmoov kaolin tuaj yeem hloov kho los ntawm kev ntxuav, calcining lossis kev hloov kho qhov chaw kom sib xyaw ua ke rau hauv ntau yam kev tsim khoom, ua haujlwm ua tus txhim kho zais cia uas ua rau kev ua haujlwm ntawm cov khoom kawg tsis muaj kev saib xyuas rau nws tus kheej.

Cov txheej txheem ua cov yam ntxwv ua haujlwm ntawm cov hmoov kaolin kom phim cov kev xav tau ntawm kev lag luam. Kev ntxuav tshem tawm cov khoom tsis huv thiab cov noob loj, ua kom huv si thiab dawb kom haum rau cov ntawv thov uas xav tau qhov zoo nkauj huv si. Kev calcining suav nrog kev cua sov hauv qab kev tswj hwm, uas tshem tawm cov dej noo thiab cov organic, hloov cov qauv siv lead ua kom muaj zog, kev ruaj khov thermal thiab opacity - qhov tseem ceeb rau cov khoom uas raug rau qhov kub siab lossis qhov chaw nyuaj. Kev hloov kho qhov chaw kho cov khoom me me nrog cov neeg sawv cev sib txuas, txhim kho kev sib raug zoo nrog cov organic matrices xws li resins thiab polymers, ua kom ntseeg tau tias muaj kev sib kis zoo ib yam thiab ua kom muaj zog ntau dua hauv cov ntaub ntawv sib xyaw.

Kev lag luam nplaum thiab sealant vam khom ntau rau hmoov kaolin ua cov khoom siv ua haujlwm. Nws ua kom cov nplaum nplaum nplaum zoo dua, tiv thaiv kev ntws ntau dhau thaum siv thiab ua kom muaj kev sib txuas zoo. Qhov loj me ntawm cov khoom me me thiab lub peev xwm muaj zog tiv thaiv kev sib sau ua ke thiab kev faib ua pawg, tswj kev sib xws ntawm cov nplaum thaum khaws cia. Hmoov kaolin kuj ua rau muaj zog sib txuas los ntawm kev txhim kho kev sib txuas ntawm cov nplaum thiab cov khoom siv - txawm tias sib txuas ntoo, hlau lossis yas, nws tsim cov khoom sib txuas ruaj khov, ruaj khov uas tiv taus kev tev thiab txiav. Hauv cov sealant kev tsim kho, nws ua rau muaj kev ywj pheej thiab kev tiv thaiv huab cua, tso cai rau cov sealant hloov kho rau qhov kub thiab txias hloov pauv yam tsis muaj kev tawg, tiv thaiv cov tsev los ntawm dej thiab cua nkag.

Cov khoom siv refractory suav tias kaolin hmoov rau nws qhov kev ruaj khov thermal zoo kawg thiab qhov kub siab melting. Sib xyaw nrog lwm cov zaub mov uas tiv taus cua sov, nws tsim cov qauv rau cov cib refractory, castables thiab cov linings cub tawg - cov khoom tseem ceeb hauv cov khoom siv kub siab. Cov ntaub ntawv no khaws cov qauv ruaj khov txawm tias nyob hauv qhov kub heev, tsim cov txheej txheem tiv thaiv uas tiv thaiv cov cub tawg, reactors thiab kilns los ntawm kev puas tsuaj. Kaolin hmoov tiv taus thermal shock tiv thaiv kev tawg los ntawm kev hloov pauv kub tam sim ntawd, uas feem ntau pom hauv kev ua hlau, kev tsim iav thiab kev tsim cement. Nws cov khoom me me sau qhov sib txawv ntawm cov khoom siv refractory coarser, txhim kho qhov ceev thiab lub zog ntawm cov khoom kawg, ntev lub neej kev pabcuam thiab txo cov nqi txij nkawm.

Kev lag luam kua mem siv cov hmoov kaolin los ua kom kev luam ntawv zoo dua. Nws ua kom cov kua mem ntws tau zoo, ua kom yooj yim hloov ntawm lub phaj luam ntawv mus rau lub substrate thiab tiv thaiv cov teeb meem xws li cov kua mem sib sau ua ke lossis tsis sib npaug. Lub peev xwm ruaj khov ua rau cov xim sib npaug, tswj cov xim sib xws thoob plaws hauv cov haujlwm luam ntawv. Cov hmoov kaolin ua rau lub zog npog ntawm cov kua mem ua rau cov txheej nyias nyias ua tiav tag nrho, thaum ua kom qhuav sai dua los ntawm kev nqus cov dej noo lossis cov kuab tshuaj - txo cov kev pheej hmoo ntawm kev ua qias tuaj thiab ua kom muaj txiaj ntsig zoo dua. Kev tsis muaj tshuaj lom neeg ua kom sib xws nrog cov resins, cov xim thiab cov kuab tshuaj, zam kev tsis xav tau uas yuav ua rau cov kua mem tsis zoo lossis lub neej khaws cia poob qis.

Kev lag luam yas thiab cov khoom sib xyaw siv cov hmoov kaolin ua cov khoom siv ntxiv dag zog. Ntxiv rau cov yas formulations, nws ua rau kom muaj zog, tiv taus cua sov thiab ruaj khov yam tsis muaj kev cuam tshuam rau kev ua haujlwm. Cov hmoov kaolin hloov kho ntawm qhov chaw sib npaug hauv cov yas matrices, tsim cov bonds muaj zog uas txhim kho lub zog tensile thiab kev cuam tshuam. Qhov no tso cai rau kev tsim cov khoom yas sib dua, ruaj khov dua rau cov khoom siv tsheb, cov khoom siv hluav taws xob thiab cov khoom siv tsim kho. Hauv cov khoom sib xyaw, nws ua haujlwm ua cov khoom sau uas txhawb cov khoom siv kho tshuab, txo kev vam khom rau cov xov hluavtaws kim thaum tswj kev ua haujlwm ntawm cov qauv.

Cov khoom siv pabcuam luam ntawv thiab ntim khoom kuj tau txais txiaj ntsig los ntawm cov khoom ntawm cov hmoov kaolin. Nws yog siv rau hauv cov varnishes thiab overprints los txhim kho qhov ci ntsa iab, tiv taus khawb thiab luam tawm tau zoo. Hmoov kaolin txhim kho kev sib txuas ntawm cov varnishes rau cov nto luam tawm, ua kom muaj kev tiv thaiv ntev ntev tiv thaiv kev hnav thiab cov yam ntxwv ib puag ncig. Hauv cov nplaum ntim khoom, nws ua kom cov mis ruaj khov thiab txhim kho lub zog sib txuas, ua kom cov pob khoom tseem kaw thaum lub sijhawm thauj mus los thiab khaws cia. Nws qhov dawb ntuj kuj pab tswj kom meej thiab zoo li ntawm cov khoom ntim pob tshab lossis xim dawb.
