Pyrophyllite yog cov pob zeb aluminosilicate uas muaj dej nrog cov hlaws lossis roj ci ntsa iab. Pyrophyllite ua lag luam tsis muaj ciam teb nruj nrog talc thiab saponite. Cov tshuaj lom neeg ntawm pyrophyllite zoo ib yam li cov pob zeb kaolin, thiab ob qho tib si yog cov pob zeb aluminosilicate uas muaj dej. Pyrophyllite thawj zaug siv ua khoom lag luam rau kev txiav, nrog rau cov foob, cov cwj mem pob zeb, thiab lwm yam. Nrog rau kev txhim kho ntawm kev lag luam niaj hnub no, pyrophyllite siv ua cov khoom ntim rau kev tsim cov khoom siv refractory, ceramics, papermaking, tshuaj tua kab, roj hmab, yas thiab lwm yam lag luam, thiab nws kuj tuaj yeem siv ua cov khoom siv raw xws li iav fiber thiab cement dawb. Nws cov teb thov yog dav heev.
01
Cov khoom ntawm cov pob zeb thiab cov qauv ntawm cov pob zeb
Cov mis tshuaj ntawm pyrophyllite yog Al2 [SiO4O10] (OH) 2, uas cov ntsiab lus theoretical ntawm Al2O3 yog 28.30%, SiO2 yog 66.70%, H2O yog 5.0%, Mohs hardness 1.25, density 2.65g / cm3, melting point 1700 ° c, Nws yog dawb, grey, ntsuab daj, xim av daj thiab lwm yam xim, pearl lossis roj ci, tawv, nplua, opaque lossis translucent, dawb streaks, thiab muaj kev tiv thaiv cua sov zoo thiab rwb thaiv tsev.
Cov pob zeb pyrophyllite ntshiab tsis tshua muaj nyob rau hauv xwm, thiab feem ntau yog tsim los ntawm cov pob zeb zoo sib xws, thiab lawv kuj yog av thiab fibrous. Cov zaub mov tseem ceeb symbiotic yog quartz, kaolin, thiab diaspore, ua raws li pyrite, chalcedony, opal, sericite, illite, alunite, hydromica, rutile, andalusite, kyanite, corundum, thiab dickite Tos.
02
Cov teb thov thiab cov cim qhia kev txawj
Pyrophyllite siv dav hauv cov teb ntawm cov duab puab, cov khoom siv av nplaum, iav, roj hmab, yas, ua ntawv, cov ntaub ntawv refractory, thiab cov pob zeb diamond hluavtaws.

Kev siv tshuab ua cov khoom siv mineral thiab kev siv tshuab ua cov khoom siv
Kev pab thiab kev ntxuav
①, kev sib tsoo thiab kev sib tsoo
Kev sib tsoo thiab sib tsoo ntawm pyrophyllite muaj ob lub hom phiaj: ib qho yog los npaj pyrophyllite thiab cov khoom siv tsis huv monomer dissociated hmoov rau kev ua haujlwm huv ntawm kev ua kom zoo, thiab lwm qhov yog los cuam tshuam ncaj qha nrog pyrophyllite uas nws qhov kev dawb huv tuaj yeem ua tau raws li qhov xav tau ntawm daim ntawv thov. Ua tiav rau hauv cov khoom hmoov. Vim tias pyrophyllite yog softer thiab cov khoom tsis huv yog nyuaj dua, nws yog ib qho tseem ceeb heev uas yuav tsum siv cov khoom siv sib tsoo xaiv rau hom kev ua kom zoo.
②, Kev Xaiv
Qhov sib txawv ntawm cov khoom sib xyaw sab hauv ntawm pyrophyllite pom tseeb dua hauv qhov tsos. Nws feem ntau muaj cov ntaub ntawv xws li lub teeb thiab xim. Nws tuaj yeem raug txheeb xyuas los ntawm tes tawm cov hlau loj impurity, lossis nws tuaj yeem raug txheeb xyuas los ntawm lub tshuab photoelectric sorting xws li lub tshuab ze-infrared hyperspectral ntse sorting.
③, Kev pabcuam nruab nrab ntom ntom
Qhov ceev ntawm pyrophyllite thiab cov zaub mov tsis huv tsis txawv ntau, tab sis tom qab sib tsoo, tshwj xeeb tshaj yog kev sib tsoo xaiv, qhov loj me ntawm cov zaub mov sib txawv yog txawv, thiab qhov sib txawv ntawm qhov nyuaj yog qhov pom tseeb dua. Cov zaub mov tawv feem ntau faib ua cov noob loj dua. Raws li cov yam ntxwv no, txoj kev nruab nrab ntawm kev ncua kev faib tawm thiab kev faib tawm sedimentation tuaj yeem siv rau kev xaiv.
④ Kev sib cais sib nqus
Feem ntau ntawm cov zaub mov hauv cov pyrophyllite ore tsis pom tseeb magnetically, thiab cov hlau-muaj impurities tsis muaj zog. Cov hlau tshuab tsim tawm thaum lub sijhawm crushing thiab sib tsoo txheej txheem tuaj yeem sib cais los ntawm lub zog magnetic teb tsis muaj zog. Cov hlau oxide thiab hlau silicate uas twb muaj lawm yuav tsum tau sib cais los ntawm cov nplhaib ntsug thiab electromagnetic pulp. High-gradient magnetic separator rau high-gradient magnetic sib cais ntawm cov ntaub ntawv.
⑤ Kev Ua Ntsuag
Thaum cov hlau tsis huv yog sulfides, xanthates tuaj yeem siv rau kev flotation kom tshem tawm hlau, thaum cov hlau tsis huv yog oxides, roj av sulfonate tuaj yeem siv rau kev flotation kom tshem tawm hlau, thiab pyrophyllite thiab quartz tuaj yeem sib cais los ntawm cov rog acids lossis amines. Siv ua tus sau rau kev sib cais flotation hauv alkaline lossis acidic media.
⑥. Kev ntxuav tshuaj lom neeg
Rau cov hlau uas tsis dawb thiab txoj kev siv lub cev tsis yooj yim ua kom tau raws li qhov yuav tsum tau ua ntawm cov ntsuas zoo, cov txheej txheem txo cov tshuaj dawb siv tau rau kev ntxuav tshuaj.
Kev sib tsoo zoo heev
Thaum pyrophyllite siv rau hauv kev ua ntawv, yas, roj hmab, cov ntaub ntawv refractory thiab lwm yam teb, nws yuav tsum tau crushed superfinely. Tam sim no, muaj ob txoj kev, qhuav thiab ntub. Cov txheej txheem qhuav feem ntau siv lub tshuab sib tsoo ultra-fine, thiab cov txheej txheem ntub feem ntau siv lub tshuab sib tsoo stripper thiab lub tshuab sib tov.
Kev hloov kho qhov chaw
Feem ntau, kev hloov kho ntawm cov hmoov pyrophyllite siv cov tshuaj silane thiab titanate coupling agents. Kev hloov kho ntawm cov hmoov pyrophyllite muaj ob txoj kev: txoj kev qhuav thiab txoj kev ntub.
Pob zeb diamond tsim
Pyrophyllite tsis muaj zog tshuaj lom neeg, tiv taus kub thiab siab, muaj hluav taws xob zoo heev thiab rwb thaiv tsev thermal, lub zog shear qis thiab lwm yam khoom, muaj kev sib txhuam sab hauv zoo tagnrho thiab kev ua haujlwm hloov khoom khov, thiab siv dav hauv cov thev naus laus zis siab heev niaj hnub no. Cov khoom siv xa khoom siab heev thiab kaw tseem ceeb tshaj plaws hauv kev lag luam khoom siv superhard. Pyrophyllite thiab cov hlau nplaum, cov hlau nplaum carbon tuaj yeem tau txais cov pob zeb diamond tsim nyog los ntawm kev kub, siab thiab tshuaj ntxuav.
