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 ekumgangatho ophezulu wezinto ezichasayo 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 be-3.56 ukuya kwi-3.68g / cm3. Amacandelo aphambili yi-kyanite kunye nenani elincinci le-sillimanite.
Iikristale ze-Andalusite ziyi-columnar, phantse isikwere kwicandelo elinqamlezayo, 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) ekubaleni kwiqondo lokushisa eliphezulu, kwaye idlulele kukwandiswa kwevolumu. 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, i-synthesizing mullite kwiqondo lokushisa eliphezulu, kunye ne-crystalline kunye ne-kyanite ebonakalayo 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 nobushushu obuphezulu, izinto eziphikisayo ezingenakulinganiswa |
| 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 ibonakala njengento ekrwada yamatye anqabileyo |
| Iyeza | Ukwenziwa kwamazinyo emboleko, ukudityaniswa kweepleyiti zokudibanisa amathambo |
| Ikhemikhali | I-mullite yokulungiswa kobushushu obuphezulu, izinto ezixhathisa iasidi, 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
Kwi-coarse-grained inlaid kunye ne-mixed inlaid kyanite minerals, indlela yokwahlukana komxhuzulane 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 zemagnethi, okanye ukugxila kwintsebenzo yokuphinda kususwe ukungcola okufana nentsimbi kunye ne-titanium kunye nokuphucula ibakala lokugxila. Isixhobo sokwahlula imagnethi siquka isahluli segubu lamagnetic, isahluli semagnethi yepleyiti, isandi esithe nkqo sesahluli semagnethi ephezulu, njl.
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.
