Cov zaub mov Kyanite muaj xws li kyanite, andalusite, thiab sillimanite. Peb yam no yog homogeneous thiab multiphase variants, thiab cov tshuaj mis yog AI2SlO5, muaj AI2O362.93% thiab SiO237.07%. Cov zaub mov Kyanite muaj refractoriness siab, tshuaj stability thiab mechanical zog. Lawv yog cov khoom siv raw ntawm cov khoom siv refractory zoo thiab siv dav hauv kev tsim cov khoom siv refractory, advanced ceramics, aluminium-silicon alloys thiab refractory fibers.
Cov Khoom Siv Ore thiab Cov Qauv Mineral
Cov pob zeb kyanite yog cov pob zeb tiaj tiaj, xiav lossis xiav-grey, vitreous thiab pearly. Qhov nyuaj ntawm qhov kev taw qhia txuas ntxiv ntawm cov pob zeb sib luag yog 5.5, thiab qhov nyuaj ntawm qhov kev taw qhia txuas ntxiv ntawm cov pob zeb perpendicular yog 6.5 txog 7, yog li nws hu ua "ob lub pob zeb tawv", thiab qhov ceev yog 3.56 txog 3.68g / cm3. Cov khoom tseem ceeb yog kyanite thiab me ntsis ntawm sillimanite.
Cov pob zeb Andalusite yog cov ncej, yuav luag plaub fab hauv seem hla, thiab teeb tsa ua ib daim duab hla ib txwm ntawm seem hla. 3.2g/cm3.
Cov siv lead ua sillimanite zoo li koob, feem ntau yog cov pob zeb radial thiab fibrous, grey-xim av lossis grey-ntsuab, vitreous, 7 hardness, thiab 3.23-3.27g / cm3 ceev.
Cov zaub mov hauv pawg Kyanite raug hloov mus ua mullite (tseem hu ua mullite) thiab silica (cristobalite) sib xyaw thaum calcination ntawm qhov kub siab, thiab dhau los ua qhov ntim nthuav dav. Cov zaub mov cuam tshuam suav nrog biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite thiab lwm yam zaub mov.
Cov cheeb tsam thov thiab cov cim qhia kev txawj
Cov ntaub ntawv refractory yog cov teb tseem ceeb ntawm cov zaub mov kyanite, uas tuaj yeem siv rau kev ua cib, txhim kho kev ua haujlwm kub ntawm cov khoom refractory, synthesizing mullite ntawm qhov kub siab, thiab crystalline thiab pob tshab kyanite thiab andalusite tuaj yeem siv ua pob zeb diamond lossis khoom siv tes ua.
Cov kev siv tseem ceeb ntawm cov zaub mov kyanite:
| Daim ntawv thov teb | Daim ntawv thov tseem ceeb |
| Cov khoom siv hluav taws xob | Ua cov cib refractory, txhim kho cov cib kub tiv taus, cov ntaub ntawv refractory tsis zoo |
| Cov Khoom Siv Ua Los Ntawm Av nplaum | Cov Khoom Uas Ua Los Ntawm Av nplaum Siab, Cov Khoom Uas Ua Los Ntawm Av nplaum Kev Siv Tshuab |
| Kev lag luam hlau | Lub zog siab silicon txhuas alloy |
| Cov fiber refractory | Cov ntaub thaiv hluav taws xob, cov ntaub thaiv hluav taws xob |
| pob zeb diamond | Crystal granularity, ci thiab pob tshab ua raw khoom rau gemstones |
| Tshuaj kho mob | Kev tsim cov hniav cuav, cov pob zeb sib xyaw rau cov phaj txuas pob txha tawg |
| Tshuaj lom neeg | Kev ua haujlwm kub siab mullite, cov khoom siv tiv taus kua qaub, lub raj ntsuas kub siab |
Vim yog qhov sib txawv ntawm kev ua tau zoo ntawm ntau yam khoom siv raw, kev siv thiab cov txheej txheem thov, muaj cov kev cai sib txawv rau qhov zoo ntawm kyanite concentrates.
Kev siv tshuab ua khoom noj - kev ua kom huv thiab kev ua kom huv
Txoj kev ua kom zoo thiab cov txheej txheem thev naus laus zis ntawm cov zaub mov kyanite feem ntau nyob ntawm cov yam ntxwv ntawm cov zaub mov, feem ntau yog flotation, gravity sib cais thiab sib nqus sib cais, thiab lwm yam.
①Kev Ua Dej
Flotation yog txoj kev pabcuam tseem ceeb rau cov zaub mov kyanite, tab sis feem ntau nws yuav tsum tau ua ke nrog lwm txoj hauv kev kom ua tau raws li qhov xav tau ntawm cov ntsuas kev lag luam. Feem ntau siv Gravity desliming lossis flotation tom qab sib cais sib nqus. Cov neeg sau khoom siv cov roj fatty acids thiab lawv cov ntsev, qhov nruab nrab lossis tsis muaj zog acidic pulp PH tus nqi, cov yam tseem ceeb uas cuam tshuam yog kev sib tsoo fineness, impurity zog, desliming nyhuv, tshuaj lom neeg system thiab pulp PH tus nqi.
② Rov xaiv dua
Rau cov pob zeb kyanite uas muaj cov pob zeb loj thiab cov pob zeb sib xyaw ua ke, feem ntau siv txoj kev sib cais ntawm lub ntiajteb txawj nqus, thiab cov khoom siv sib cais ntawm lub ntiajteb txawj nqus suav nrog lub rooj co, lub cua daj cua dub, lub nruab nrab hnyav thiab lub qhov kauv.
③Txoj kev sib cais sib nqus
Nws yog ib txoj kev tseem ceeb hauv kev ua kom kyanite zoo. Feem ntau nws siv rau kev npaj cov khoom siv raw xaiv los rov qab lossis tshem tawm cov khoom sib nqus, lossis rau kev ua haujlwm rov ua dua kom tshem tawm cov khoom tsis huv xws li hlau thiab titanium thiab txhim kho qib sib nqus. Cov khoom siv sib cais sib nqus suav nrog lub nruas sib nqus sib cais, phaj sib nqus sib cais, lub nplhaib ntsug siab gradient sib nqus sib cais, thiab lwm yam. Cov khoom siv sib cais sib nqus thiab cov txheej txheem ntws raug txiav txim siab raws li lub zog ntawm cov hlau nplaum tsis huv.
Cov khoom siv mullite ua los ntawm cov khoom siv hluavtaws
Mullite yog ib yam khoom siv refractory zoo. Muaj ob txoj kev los ua mullite los ntawm cov khoom siv raw kyanite. Ib qho yog calcine ncaj qha los tsim cov khoom nruab nrab-aluminium mullite clinker, thiab lwm qhov yog ntxiv bauxite, alumina thiab zircon. Cov pob zeb, thiab lwm yam. raug calcined ntawm qhov kub siab los tsim mullite lossis zircon mullite clinker.
