Amaminerali e-Kyanite afaka i-kyanite, i-andalusite, ne-sillimanite. Okuthathu kuyizinhlobonhlobo ze-homogeneous kanye ne-multiphase, futhi ifomula yamakhemikhali yi-AI2SlO5, equkethe i-AI2O362.93% ne-SiO237.07%. Amaminerali e-Kyanite ane-refractoriness ephezulu, ukuzinza kwamakhemikhali namandla emishini. Ziyizinto ezingavuthiwe zezinto ezisezingeni eliphakeme eziphikisayo futhi zisetshenziswa kakhulu ekukhiqizeni izinto eziphikisayo, izitsha zobumba ezithuthukisiwe, ama-aluminium-silicon alloys kanye nemicu ephikisayo.
Izakhiwo ze-Ore kanye nesakhiwo samaminerali
Amakristalu e-Kyanite anekholomu eyisicaba, eluhlaza okwesibhakabhaka noma eluhlaza okwesibhakabhaka, i-vitreous ne-pearly. Ukuqina kwe-parallel crystal extension direction yi-5.5, futhi ubulukhuni be-perpendicular crystal extension direction buyi-6.5 kuya ku-7, ngakho-ke kubizwa ngokuthi "amatshe aqinile amabili", futhi ukuminyana ku-3.56 kuya ku-3.68g / cm3. Izingxenye eziyinhloko ziyi-kyanite kanye nenani elincane le-sillimanite.
Amakristalu e-Andalusite ayikholomu, acishe abe isikwele esigabeni esiphambanayo, futhi ahlelwe ngendlela evamile esiphambanweni. 3.2g/cm3.
Amakristalu e-Sillimanite afana nenaliti, ngokuvamile ama-radial and fibrous aggregates, gray-brown noma grey-green, vitreous, 7 hardness, kanye no-3.23-3.27g/cm3 ukuminyana.
Amaminerali eqembu le-Kyanite aguqulwa abe yingxube ye-mullite (ebuye yaziwe ngokuthi i-mullite) ne-silica (cristobalite) lapho kubalwa ezingeni lokushisa eliphezulu, futhi idlulele ekukhulisweni kwevolumu. Amaminerali ahlobene ahlanganisa i-biotite, i-muscovite, i-sericite, i-quartz, i-graphite, i-plagioclase, i-garnet, i-rutile, i-pyrite, i-chlorite namanye amaminerali.
Izindawo zokufaka izicelo kanye nezinkomba zobuchwepheshe
Izinto eziphikisayo ziyizinkambu eziyinhloko zokufaka isicelo samaminerali e-kyanite, angasetshenziselwa ukwenza izitini, ukuthuthukisa ukusebenza kokushisa okuphezulu kwemikhiqizo ephikisayo, ukuhlanganiswa kwe-mullite ekushiseni okuphezulu, kanye ne-crystalline ne-kyanite esobala kanye ne-andalusite ingasetshenziswa njengamatshe ayigugu noma imisebenzi yezandla.
Ukusetshenziswa okuyinhloko kwamaminerali e-kyanite:
| Inkambu yohlelo lokusebenza | Uhlelo lokusebenza oluyinhloko |
| I-Refractory | Ukwenza izitini eziphikisayo, ukuthuthukisa izitini zokumelana nokushisa okuphezulu, izinto eziphikisayo ezingabunjiwe |
| I-Ceramics | I-Ceramics Ethuthukisiwe, I-Technical Ceramics |
| I-Metallurgy | Amandla aphezulu we-silicon aluminium alloy |
| I-fiber refractory | I-refractory lining, i-spark plug lining insulator |
| itshe eliyigugu | I-Crystal granularity, ekhanyayo futhi esobala njengento eluhlaza yamatshe ayigugu |
| Umuthi | Ukwenziwa kwamazinyo okufakelwa, inhlanganisela yamapuleti okuxhumana amathambo aphukile |
| Amakhemikhali | I-mullite yokucubungula izinga lokushisa eliphezulu, izinto ezimelana ne-asidi, ishubhu lokulinganisa izinga lokushisa eliphezulu |
Ngenxa yomehluko wokusebenza kwezinto ezingahluziwe zamaminerali ahlukahlukene, ukusetshenziswa kanye namazinga enqubo yokufaka isicelo, kunezidingo ezihlukile zekhwalithi ye-kyanite egxile.
Ubuchwepheshe bokucubungula - ukuhlomula nokuhlanzwa
Indlela yokuzuza kanye nenqubo yezobuchwepheshe yamaminerali e-kyanite ikakhulukazi incike ezicini ezishumekiwe zamaminerali, ngokuvamile ukuntanta, ukuhlukaniswa kwamandla adonsela phansi kanye nokuhlukaniswa kazibuthe, njll.
①Ukuntanta
I-Flotation iyindlela eyinhloko yokuzuza kumaminerali e-kyanite, kodwa ngokuvamile idinga ukuhlanganiswa nezinye izindlela ukuze ihlangabezane nezidingo zezinkomba zezimboni. I-Gravity desliming noma ukuntanta ngemva kokuhlukana kazibuthe kuvame ukusetshenziswa. Abaqoqi basebenzisa ama-acid anamafutha kanye nosawoti wawo, inani le-PH le-pulp elingathathi hlangothi noma eline-asidi ebuthakathaka, izici ezinomthelela oyinhloko ukucoleka kokugaya, izakhiwo ezingcolile, umphumela we-desliming, isistimu yamakhemikhali kanye nenani le-PH ye-pulp.
②Khetha kabusha
Kumaminerali e-kyanite ahlanganisiwe anezinhlamvu ezimahhadlahhadla, indlela yokwehlukanisa amandla adonsela phansi isetshenziswa kakhulu, futhi imishini yokuhlukanisa amandla adonsela phansi ihlanganisa itafula elinyakazayo, isishingishane, i-medium esindayo kanye ne-spiral chute.
③Indlela yokuhlukanisa umazibuthe
Kuyindlela edingekayo ekuzuzeni i-kyanite. Ngokuvamile isetshenziselwa ukulungiswa kwezinto ezingavuthiwe ezikhethiwe ukuze kubuyiselwe noma kukhishwe imikhiqizo kazibuthe, noma ukugxilisa kakhulu ukucubungula kabusha ukuze kukhishwe ukungcola okufana nensimbi ne-titanium futhi kuthuthukiswe izinga lokugxilisa ingqondo. Imishini yokuhlukanisa kazibuthe ihlanganisa isihlukanisi sesigubhu sikazibuthe, isihlukanisi sikazibuthe sepuleti, isihlukanisi esiqondile esiqondile se-gradient kazibuthe, njll. Imishini yokuhlukanisa kazibuthe nokugeleza kwenqubo kunqunywa ngokwamandla kamagnetism okungcola.
I-mullite yokwenziwa
I-Mullite iyinto ephezulu yokuphikisa. Kunezinqubo ezimbili zokwenziwa kwe-mullite kusuka kuzinto zokusetshenziswa ze-kyanite. Enye iwukuba i-calcine ngqo yakhe i-medium-aluminium mullite clinker, kanti enye iwukwengeza i-bauxite, i-alumina ne-zircon. Amatshe, njll. abalwa emazingeni okushisa aphezulu ukuze enze i-mullite noma i-zircon mullite clinker.
