Iiminerali ze-Kyanite ziquka i-kyanite, i-andalusite, kunye ne-sillimanite.Ezi zintathu zi-homogeneous kunye ne-multiphase variants, kunye ne-chemical formula yi-AI2SlO5, equkethe i-AI2O362.93% kunye ne-SiO237.07%.Amaminerali e-Kyanite ane-refractoriness ephezulu, ukuzinza kweekhemikhali kunye namandla omatshini.Ziyimpahla ekrwada yomgangatho ophezulu wezinto eziphikisayo kwaye zisetyenziswa ngokubanzi kwimveliso yezinto eziphikisayo, iiseramics eziphambili, i-aluminium-silicon alloys kunye ne-refractory fibers.
Iipropati zentsimbi kunye noLwakhiwo lweziMbiwa
Iikristale ze-Kyanite ziyi-columnar ecaba, eluhlaza okwesibhakabhaka okanye eluhlaza okwesibhakabhaka, i-vitreous kunye ne-pearly.Ubunzima bendlela yokwandiswa kwe-crystal ehambelanayo yi-5.5, kwaye ubunzima be-perpendicular crystal extension direction yi-6.5 ukuya kwi-7, ngoko kuthiwa "amatye amabini anzima", kwaye ubuninzi buyi-3.56 ukuya kwi-3.68g / cm3.Amacandelo aphambili yi-kyanite kunye nenani elincinci le-sillimanite.
Iikristale ze-Andalusite ziyi-columnar, phantse isikwere kwicandelo lomnqamlezo, kwaye zicwangciswe ngendlela eqhelekileyo yomnqamlezo kwicandelo lomnqamlezo.3.2g/cm3.
Iikristale ze-Sillimanite zifana nenaliti, ngokuqhelekileyo i-radial kunye ne-fibrous aggregates, i-gray-brown okanye i-gray-green, i-vitreous, i-7 yobunzima, kunye ne-3.23-3.27g / cm3 yobuninzi.
Iiminerali zeqela le-Kyanite ziguqulwa zibe ngumxube we-mullite (ekwaziwa ngokuba yi-mullite) kunye ne-silica (cristobalite) phezu kokubala kwiqondo lokushisa eliphezulu, kwaye idlule kukwandiswa komthamo.Amaminerali adibeneyo aquka i-biotite, i-muscovite, i-sericite, i-quartz, i-graphite, i-plagioclase, i-garnet, i-rutile, i-pyrite, i-chlorite kunye nezinye iiminerali.
Iindawo zesicelo kunye nezalathi zobugcisa
Izinto ezichasayo ziyimimandla ephambili yesicelo se-kyanite minerals, engasetyenziselwa ukwenza izitena, ukuphucula ukusebenza kobushushu obuphezulu bemveliso ye-refractory, ukudibanisa i-mullite kwiqondo lokushisa eliphezulu, kunye ne-crystalline kunye ne-kyanite ecacileyo kunye ne-andalusite ingasetyenziswa njengamatye anqabileyo okanye imisebenzi yezandla.
Ukusetyenziswa okuphambili kweeminerali ze-kyanite:
| Indawo yosetyenziso | Isicelo esingundoqo |
| I-Refractory | Ukwenza izitena eziphikisayo, ukuphucula izitena zokumelana nokushisa okuphezulu, izinto ezinqambileyo ezingenamilo |
| iiCeramics | IiCeramics eziPhezulu, iiCeramics zobuGcisa |
| Isinyithi | Amandla aphezulu e-silicon aluminium alloy |
| I-fiber ephikisayo | I-refractory lining, i-spark plug lining insulator |
| ilitye elinqabileyo | I-Crystal granularity, eqaqambileyo kwaye ecacileyo njengemathiriyeli ekrwada yamatye anqabileyo |
| Iyeza | Ukwenziwa kwamazinyo emboleko, ukudityaniswa kweepleyiti zokudibanisa amathambo |
| Ikhemikhali | I-mullite yokulungisa ubushushu obuphezulu, imathiriyeli ekwaziyo ukumelana ne-asidi, ityhubhu yokulinganisa ubushushu obuphezulu |
Ngenxa yokungafani kokusebenza kwezinto ezahlukeneyo zamaminerali, ukusetyenziswa kunye namanqanaba enkqubo yesicelo, kukho iimfuno ezahlukeneyo zomgangatho we-kyanite concentrates.
Itekhnoloji yokucubungula - ukuxhamla kunye nokuhlanjululwa
Indlela yokuzuza kunye nenkqubo yezobuchwepheshe yamaminerali e-kyanite ikakhulu ixhomekeke kwiimpawu ezifakwe kwiiminerali, ngokubanzi ukujikeleza, ukuhlukana komxhuzulane kunye nokuhlukana kwamagnetic, njl.
①Ukuphaphatheka
I-Flotation yindlela ephambili yokuxhamla kwiiminerali ze-kyanite, kodwa ngokuqhelekileyo kufuneka zidibaniswe nezinye iindlela zokuhlangabezana neemfuno zezalathisi zoshishino.I-Gravity desliming okanye i-flotation emva kokwahlulwa kwemagnethi ihlala isetyenziswa.Abaqokeleli basebenzisa i-fatty acids kunye neetyuwa zabo, i-neutral okanye i- weakly acidic pulp ixabiso le-PH, ezona zinto zichaphazelayo ziyi-fineness yokugaya, iipropati ezingcolileyo, i-desliming effect, inkqubo yeekhemikhali kunye nexabiso le-PH ye-pulp.
②Khetha kwakhona
Kwiiminerali ze-kyanite ezixutywe kunye ne-coarse-grained inlaid inlaid, indlela yokwahlula amandla obunzima isetyenziswa kakhulu, kwaye izixhobo zokwahlula umxhuzulane zibandakanya itafile eshukumayo, i-cyclone, i-medium enzima kunye ne-spiral chute.
③Indlela yokwahlula ngokwemagnethi
Yindlela eyimfuneko kwi-kyanite beneficiation.Ngokuqhelekileyo isetyenziselwa ukulungiswa kwezixhobo ezikhethiweyo zokubuyisela okanye ukususa iimveliso zemagneti, okanye ukugxila kwintsebenzo yokuphinda kususwe ukungcola okufana nentsimbi kunye ne-titanium kunye nokuphucula ibakala lokugxila.Isixhobo sokwahlula imagnethi siquka isahluli segubu lamagnetic, isahluli semagnethi kwipleyiti, isandi esithe nkqo sesahluli semagnethi ephezulu, njl.njl. Isixhobo sokwahlulwa kwemagnethi kunye nokuhamba kwenkqubo kumiselwa ngokokomelela kwemagnethi yokungcola.
Synthetic mullite
I-Mullite yimathiriyeli yomgangatho ophezulu we-refractory.Kukho iinkqubo ezimbini zokwenza i-mullite evela kwi-kyanite ekrwada.Enye i-calcine ngokuthe ngqo ukwenza i-medium-aluminium mullite clinker, kwaye enye yongeza i-bauxite, i-alumina kunye ne-zircon.Amatye, njl njl. afakwe kwi-calcined kwiqondo lokushisa eliphezulu ukwenza i-mullite okanye i-zircon mullite clinker.
