Feldspar yog ib qho tseem ceeb tshaj plaws ntawm cov pob zeb tsim cov pob zeb hauv lub ntiaj teb pob zeb.Potassium los yog sodium-nplua nuj feldspar yog dav siv nyob rau hauv ceramics, enamel, iav, abrasives, thiab lwm yam kev lag luam sectors.Potassium feldspar, vim nws cov ntsiab lus ntawm cov poov tshuaj ntau thiab ua cov khoom siv tsis yog dej-soluble potassium, tuaj yeem siv rau yav tom ntej rau kev tsim cov potash chiv, ua rau nws yog ib qho tseem ceeb ntawm cov pob zeb hauv av.Feldspar muaj cov ntsiab lus tsis tshua muaj xws li rubidium thiab cesium tuaj yeem ua cov pob zeb hauv av rau rho tawm cov ntsiab lus no.Cov xim zoo nkauj feldspar tuaj yeem siv los ua cov pob zeb zoo nkauj thiab cov gemstones semiprecious.
Sib nrug los ntawm kev ua raw khoom rau kev lag luam iav (suav txog li 50-60% ntawm tag nrho kev noj), feldspar kuj tseem siv rau hauv kev lag luam ceramics (30%), nrog rau cov khoom siv tshuaj, abrasives, fiberglass, vuam electrodes, thiab lwm yam kev lag luam.
iav Flux
Feldspar yog ib qho tseem ceeb ntawm cov iav sib tov.Nrog siab Al₂O₃ cov ntsiab lus thiab cov ntsiab lus hlau tsawg, feldspar melts ntawm qhov kub thiab txias thiab muaj ntau yam melting.Nws yog tsuas yog siv los ua kom cov ntsiab lus alumina hauv cov iav sib tov, txo qhov kub thiab txias, thiab nce cov ntsiab lus alkali, yog li txo cov alkali siv.Tsis tas li ntawd, feldspar melts maj mam rau hauv iav, tiv thaiv kev tsim cov muaju uas tuaj yeem ua rau cov khoom puas.Feldspar kuj pab tswj cov viscosity ntawm iav.Feem ntau, potassium los yog sodium feldspar yog siv nyob rau hauv ntau yam iav sib tov.
Ceramic Lub cev Cov khoom xyaw
Ua ntej firing, feldspar ua raws li cov khoom siv raw, txo qhov ziab kom qhuav thiab deformation ntawm lub cev, txhim kho kev ua haujlwm kom qhuav, thiab ua kom lub sijhawm ziab kom luv.Thaum lub sij hawm firing, feldspar ua raws li ib tug flux kom txo cov hluav taws kub kub, txhawb lub melting ntawm quartz thiab kaolin, thiab yooj yim tsim ntawm mullite nyob rau hauv cov kua theem.Lub feldspar iav tsim thaum lub sij hawm melting nyob rau hauv lub mullite crystal grains nyob rau hauv lub cev, ua rau nws denser thiab txo porosity, yog li ua rau nws cov neeg kho tshuab zog thiab dielectric zog.Tsis tas li ntawd, qhov tsim ntawm feldspar iav txhim khu lub translucency ntawm lub cev.Tus nqi ntawm feldspar ntxiv rau hauv lub cev ceramic txawv raws li cov khoom siv raw thiab cov khoom xav tau.
Ceramic Glaze
Ceramic glaze yog tsim los ntawm feldspar, quartz, thiab av nplaum, nrog cov ntsiab lus feldspar li ntawm 10-35%.Hauv kev lag luam ceramics (ob lub cev thiab glaze), poov tshuaj feldspar feem ntau yog siv.
Physical thiab Chemical Properties
Feldspar yog cov ntxhia dav dav hauv ntiaj teb, nrog cov ntsiab lus potassium siab hu ua potassium feldspar, tshuaj sawv cev ua KAlSi₃O₈.Orthoclase, microcline, thiab sanidine yog tag nrho cov poov tshuaj feldspar minerals.Cov feldspars no muaj tshuaj lom neeg ruaj khov thiab feem ntau tiv taus acid decomposition.Lawv muaj ib tug hardness ntawm 5.5-6.5, lub ntiajteb txawj nqus ntawm 2.55-2.75 t / m³, thiab ib tug melting point ntawm 1185-1490 ° C.Cov minerals uas feem ntau muaj xws li quartz, muscovite, biotite, beryl, garnet, thiab me me ntawm magnetite, columbite, thiab tantalite.
Kev faib tawm ntawm Feldspar Deposits
Feldspar deposits feem ntau yog muab faib ua ob hom raws li lawv cov keeb kwm:
1. **Gneiss lossis Migmatitic Gneiss**: Qee cov hlab ntsha tshwm sim hauv granite lossis pob zeb loj, lossis hauv lawv thaj chaw sib cuag.Cov ore feem ntau yog concentrated nyob rau hauv feldspar thaiv cheeb tsam ntawm pegmatites los yog txawv feldspar pegmatites.
2. **Igneous Pob Zeb Hom Feldspar Deposits**: Cov deposits no tshwm sim nyob rau hauv acidic, nruab nrab, thiab alkaline igneous pob zeb.Cov uas pom hauv cov pob zeb alkaline yog qhov tseem ceeb tshaj plaws, xws li nepheline syenite, ua raws li granite, albite granite, orthoclase granite, thiab quartz orthoclase granite deposits.
Raws li cov txheej txheem mineralization ntawm feldspar, feldspar deposits muab faib ua igneous pob zeb hom, pegmatite hom, weathered granite hom, thiab sedimentary pob zeb hom, nrog pegmatite thiab igneous pob zeb hom yog lub ntsiab sawv daws yuav.
Txoj kev sib cais
- ** Phau ntawv sorting **: Raws li qhov pom tseeb qhov sib txawv ntawm cov duab thiab xim los ntawm lwm yam gangue minerals, phau ntawv sorting yog ua hauj lwm.
- ** Sib Nqus Sib Nqus **: Tom qab sib tsoo thiab sib tsoo, cov khoom sib nqus sib nqus xws li phaj sib nqus sib nqus, LHGC ntsug nplhaib siab gradient sib nqus sib nqus, thiab HTDZ electromagnetic slurry sib nqus sib nqus yog siv los tshem tawm cov hlau nplaum tsis muaj zog, titanium, thiab lwm yam khoom tsis huv. rau purification.
- ** Flotation **: Feem ntau siv HF acid nyob rau hauv acidic tej yam kev mob, nrog amine cations li collectors rau cais feldspar los ntawm quartz.
Yog xav paub ntxiv txog Huate magnetic separators thiab seb lawv tuaj yeem pab ua kom huv thiab sib cais ntawm feldspar thiab lwm yam minerals, mus saib peb lub vev xaib.Huate Sib Nqus Sib Nqus Separator muaj cov txheej txheem sib nqus sib nqus sib nqus kom haum rau koj cov kev xav tau kev lag luam.
