Pyrophyllite yog dej-muaj aluminosilicate ntxhia nrog pearl lossis roj luster. Kev lag luam pyrophyllite tsis muaj kev txwv nruj nrog talc thiab saponite. Cov tshuaj muaj pes tsawg leeg ntawm pyrophyllite zoo ib yam li kaolin minerals, thiab ob qho tib si yog dej-muaj aluminosilicate minerals. Pyrophyllite yog thawj zaug siv los ua cov khoom lag luam rau carving, nrog rau cov ntsaws ruaj ruaj, cov cwj mem pob zeb, thiab lwm yam. Nrog rau kev txhim kho kev lag luam niaj hnub no, pyrophyllite yog siv los ua cov khoom siv rau cov khoom siv refractory, ceramics, papermaking, tshuaj tua kab, roj hmab, plastics. thiab lwm yam kev lag luam, thiab nws tseem tuaj yeem siv los ua cov khoom siv raw xws li iav fiber ntau thiab cov cement dawb. Nws daim ntawv thov teb yog qhov dav.
01
Ore zog thiab ntxhia qauv
Cov tshuaj formula 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, ntom 2.65g / cm2, melting point 2.65g / cm3. c, Nws yog dawb, grey, lub teeb ntsuab, daj-xim av thiab lwm yam xim, pearl los yog grease luster, tawv, nplua, opaque los yog translucent, dawb streaks, thiab muaj zoo tshav kub thiab rwb thaiv tsev.
Pure pyrophyllite ntxhia aggregates yog tsis tshua muaj nyob rau hauv cov xwm, thiab feem ntau yog tsim los ntawm zoo xws li cov ntxhia aggregates, thiab lawv kuj yog earthy thiab fibrous. Lub ntsiab symbiotic minerals yog quartz, kaolin, thiab diaspore, ua raws li pyrite, chalcedony, opal, sericite, illite, alunite, hydromica, rutile, andalusite, kyanite, corundum, thiab dickite tos.
02
Daim ntawv thov teb thiab kev ntsuas kev ntsuas
Pyrophyllite yog dav siv nyob rau hauv cov duab puab, ceramics, iav, roj hmab, yas, papermaking, refractory khoom, thiab hluavtaws pob zeb diamond.

Mineral processing technology thiab kev siv tshuab
Kev pab thiab purification
①, crushing thiab sib tsoo
Kev sib tsoo thiab sib tsoo ntawm pyrophyllite muaj ob lub hom phiaj: ib qho yog los npaj pyrophyllite thiab impurity ntxhia monomer dissociated hmoov cov ntaub ntawv rau kev ua kom huv si ntawm cov txiaj ntsig, thiab lwm yam yog ncaj qha cuam tshuam nrog pyrophyllite uas nws purity tuaj yeem ua tau raws li qhov yuav tsum tau ua ntawm daim ntawv thov teb. Ua rau cov khoom siv hmoov. Vim tias cov pyrophyllite yog softer thiab impurities nyuaj, nws yog ib qho tseem ceeb heev uas yuav tau siv cov khoom siv crushing rau cov txiaj ntsig zoo.
②, Xaiv
Qhov sib txawv ntawm qhov sib xyaw ntawm pyrophyllite yog qhov pom tseeb dua hauv cov tsos. Nws tsuas yog muaj cov ntaub ntawv xws li lightness thiab xim. Nws tuaj yeem raug txheeb xyuas los ntawm cov hlau tsis huv loj, lossis nws tuaj yeem txheeb xyuas los ntawm photoelectric sorting tshuab xws li ze-infrared hyperspectral ntse sorting tshuab.
③, Nthuav nruab nrab tau txais txiaj ntsig
Qhov ntom ntawm pyrophyllite thiab impurity ntxhia tsis txawv ntau, tab sis tom qab sib tsoo, tshwj xeeb tshaj yog kev sib tsoo, thawj qhov loj me ntawm cov ntxhia pob zeb txawv txawv, thiab qhov sib txawv ntawm hardness yog pom tseeb dua. Cov zaub mov tawv feem ntau yog faib rau hauv coarser grain loj. Raws li cov yam ntxwv no, Txoj Kev Dense nruab nrab tau txais txiaj ntsig zoo ntawm kev ncua kev faib tawm thiab kev faib sedimentation tuaj yeem siv rau kev xaiv.
④ Sib cais sib nqus
Feem ntau ntawm cov minerals nyob rau hauv pyrophyllite ore tsis muaj magnetically pom tseeb, thiab cov hlau-muaj impurities tsis muaj zog. Cov khoom siv hlau ua thaum lub sij hawm sib tsoo thiab sib tsoo tuaj yeem sib cais los ntawm cov hlau nplaum tsis muaj zog. Cov hlau oxide thiab hlau silicate uas twb muaj lawm yuav tsum tau sib cais los ntawm ntsug rings thiab electromagnetic pulp. High-gradient magnetic separator rau high-gradient sib nqus sib cais ntawm cov ntaub ntawv.
⑤ Flotation
Thaum cov hlau ntxhia tsis huv yog sulfides, xanthates tuaj yeem siv rau flotation kom tshem tau hlau, thaum hlau impurities yog oxides, roj av sulfonate tuaj yeem siv rau flotation kom tshem tau hlau, thiab pyrophyllite thiab quartz tuaj yeem sib cais los ntawm fatty acids lossis amines. Siv raws li ib tug collector rau flotation sib cais nyob rau hauv alkaline los yog acidic media.
⑥. Tshuaj purification
Rau ore uas nws whiteness tsis zoo thiab txoj kev siv lub cev yog qhov nyuaj kom ua tau raws li qhov yuav tsum tau ua kom zoo, cov txheej txheem bleaching yuav txo tau cov tshuaj purification.
Superfine crushing
Thaum pyrophyllite siv hauv papermaking, plastics, roj hmab, cov ntaub ntawv refractory thiab lwm yam, nws yuav tsum tau crushed superfinely. Tam sim no, feem ntau yog ob txheej txheem, qhuav thiab ntub. Cov txheej txheem qhuav tsuas yog siv lub dav hlau sib tsoo zoo heev, thiab cov txheej txheem ntub dej feem ntau yog siv cov sib tsoo stripper thiab lub tshuab nplawm.
Kev hloov kho saum npoo
Kev hloov kho saum npoo ntawm pyrophyllite feem ntau siv silane thiab titanate coupling agents. Kev hloov kho saum npoo ntawm cov hmoov pyrophyllite muaj ob txoj hauv kev: txoj kev qhuav thiab txoj kev ntub dej.
Synthetic pob zeb diamond
Pyrophyllite yog cov tshuaj tsis muaj zog, tiv taus qhov kub thiab txias, muaj hluav taws xob zoo thiab thermal rwb thaiv tsev, tsis tshua muaj zog shear thiab lwm yam khoom, muaj kev sib txhuam zoo tagnrho thiab cov khoom hloov pauv, thiab tau siv dav hauv kev siv tshuab ultra-siab niaj hnub. Qhov tseem ceeb tshaj plaws ultra-siab siab kis tau tus mob thiab sealing khoom nyob rau hauv lub superhard khoom kev lag luam. Pyrophyllite thiab alloy flakes, carbon flakes tuaj yeem tau txais cov pob zeb hluavtaws uas xav tau los ntawm kev kub siab, kub siab thiab tshuaj purification txoj kev.
