Miyala ya Kyanite ikuphatikizapo kyanite, andalusite, ndi sillimanite. Miyala itatuyi ndi yofanana komanso yamitundu yambiri, ndipo njira ya mankhwala ndi AI2SlO5, yokhala ndi AI2O362.93% ndi SiO237.07%. Miyala ya Kyanite ili ndi mphamvu zambiri zotsutsana ndi zinthu zina, kukhazikika kwa mankhwala komanso mphamvu zamakanika. Ndi zipangizo zopangira zinthu zapamwamba zotsutsana ndi zinthu zina ndipo zimagwiritsidwa ntchito kwambiri popanga zinthu zotsutsana ndi zinthu zina, zinthu zadothi zapamwamba, zitsulo zotayidwa ndi silicon ndi ulusi wotsutsana ndi zinthu zina.
Katundu wa Mamineral ndi Kapangidwe kake
Makristalo a Kyanite ndi athyathyathya, abuluu kapena abuluu-imvi, a vitreous ndi a ngale. Kuuma kwa njira yolumikizirana ya kristalo ndi 5.5, ndipo kuuma kwa njira yolumikizirana ya kristalo ndi 6.5 mpaka 7, kotero amatchedwa "miyala iwiri yolimba", ndipo kuchuluka kwake ndi 3.56 mpaka 3.68g/cm3. Zigawo zazikulu ndi kyanite ndi sillimanite yochepa.
Makristalo a Andalusite ali ndi mipiringidzo, pafupifupi sikweya m'mbali, ndipo amakonzedwa mofanana ndi mipiringidzo pamzere. 3.2g/cm3.
Makristalo a Sillimanite ali ngati singano, nthawi zambiri amakhala ndi ma radial ndi fibrous aggregates, imvi-bulauni kapena imvi-green, vitreous, 7 hardness, ndi 3.23-3.27g/cm3 density.
Michere ya gulu la Kyanite imasandulika kukhala chisakanizo cha mullite (chomwe chimadziwikanso kuti mullite) ndi silica (cristobalite) ikasungunuka pa kutentha kwakukulu, ndipo imakula kwambiri. Michere yogwirizana nayo ndi biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite ndi zina.
Madera ogwiritsira ntchito ndi zizindikiro zaukadaulo
Zipangizo zoyeretsera ndizomwe zimagwiritsidwa ntchito kwambiri popanga mchere wa kyanite, zomwe zingagwiritsidwe ntchito popanga njerwa, kukonza kutentha kwa zinthu zoyeretsera, kupanga mullite pa kutentha kwakukulu, ndipo kyanite ndi andalusite zonyezimira komanso zowonekera bwino zingagwiritsidwe ntchito ngati miyala yamtengo wapatali kapena ntchito zamanja.
Ntchito zazikulu za mchere wa kyanite:
| Munda wofunsira | Ntchito yaikulu |
| Zosasinthika | Kupanga njerwa zopinga kutentha, kukonza njerwa zopinga kutentha kwambiri, zinthu zosapanga mawonekedwe zopinga kutentha |
| Zoumbaumba | Zadothi Zapamwamba, Zadothi Zaukadaulo |
| Zachitsulo | Aloyi ya aluminiyamu ya silicon yolimba kwambiri |
| Ulusi wopepuka | Chophimba chopanda mphamvu, chotchingira kuwala kwa spark plug |
| mwala wamtengo wapatali | Kuchuluka kwa kristalo, kowala komanso kowonekera bwino ngati zinthu zopangira miyala yamtengo wapatali |
| Mankhwala | Kupanga mano opangidwa ndi mano, kuphatikiza ma plate olumikizira mafupa osweka |
| Mankhwala | Mullite yokonzedwa kutentha kwambiri, zinthu zosagwira asidi, chubu choyezera kutentha kwambiri |
Chifukwa cha kusiyana kwa magwiridwe antchito a zinthu zosiyanasiyana zopangira mchere, momwe amagwiritsidwira ntchito komanso momwe amagwiritsidwira ntchito, pali zofunikira zosiyanasiyana pa mtundu wa kyanite concentrates.
Ukadaulo wokonza zinthu - kupindulitsa ndi kuyeretsa
Njira yopezera phindu ndi njira yaukadaulo ya mchere wa kyanite zimadalira makamaka mawonekedwe ophatikizidwa a mchere, makamaka kuyandama, kulekanitsa mphamvu yokoka ndi kulekanitsa maginito, ndi zina zotero.
①Kuyandama
Kuyandama ndiye njira yayikulu yopezera mchere wa kyanite, koma nthawi zambiri imafunika kuphatikizidwa ndi njira zina kuti ikwaniritse zofunikira za zizindikiro zamafakitale. Kuchotsa mphamvu yokoka kapena kuyandama pambuyo pa kulekanitsidwa kwa maginito nthawi zambiri amagwiritsidwa ntchito. Osonkhanitsa amagwiritsa ntchito mafuta acid ndi mchere wawo, PH ya pulp yopanda mbali kapena yofooka, zinthu zazikulu zomwe zimakhudza ndi kusalala kwa grinding, mawonekedwe odetsedwa, mphamvu ya desliming, dongosolo la mankhwala ndi PH ya pulp.
②Sankhaninso
Pa mchere wa kyanite wopindika komanso wosakanikirana, njira yolekanitsira mphamvu yokoka imagwiritsidwa ntchito kwambiri, ndipo zida zolekanitsira mphamvu yokoka zimaphatikizapo tebulo logwedezeka, chimphepo chamkuntho, sing'anga yolemera komanso chute yozungulira.
③Njira yolekanitsira maginito
Ndi njira yofunika kwambiri pakupangira kyanite. Nthawi zambiri imagwiritsidwa ntchito pokonzekera zinthu zopangira kuti zibwezeretse kapena kuchotsa zinthu zamaginito, kapena pokonzanso zinthu zosakaniza kuti zichotse zinyalala monga chitsulo ndi titaniyamu ndikukweza mtundu wa concentrate. Zipangizo zolekanitsa maginito zimaphatikizapo cholekanitsa maginito cha drum, cholekanitsa maginito cha mbale, cholekanitsa maginito cha vertical ring high gradient, ndi zina zotero. Zipangizo zolekanitsa maginito ndi kayendedwe ka njira zimatsimikiziridwa malinga ndi mphamvu ya maginito odetsedwa.
Mullite yopangidwa
Mullite ndi chinthu chapamwamba kwambiri chopanda mphamvu. Pali njira ziwiri zopangira mullite kuchokera ku zinthu zopangira kyanite. Choyamba ndi kupanga calcine mwachindunji kuti ipange clinker yapakati pa aluminiyamu, ndipo china ndi kuwonjezera bauxite, alumina ndi zircon. Miyala, ndi zina zotero zimasungunuka pa kutentha kwambiri kuti zipange mullite kapena zircon mullite clinker.
