Mchere wa Kyanite umaphatikizapo kyanite, andalusite, ndi sillimanite.Zitatuzi ndizosiyana komanso zosiyana, ndipo mankhwala ndi AI2SlO5, omwe ali ndi AI2O362.93% ndi SiO237.07%.Mchere wa Kyanite uli ndi refractoriness wapamwamba, kukhazikika kwa mankhwala ndi mphamvu zamakina.Ndiwo zida zopangira zida zapamwamba kwambiri zokanira ndipo zimagwiritsidwa ntchito kwambiri popanga zida zokanira, zida zadothi zapamwamba, ma aloyi a aluminium-silicon ndi ulusi wotsutsa.
Katundu wa Ore ndi Kapangidwe ka Mchere
Makatani a Kyanite ndi apilala, buluu kapena buluu-imvi, vitreous ndi ngale.Kulimba kwa njira yolumikizira kristalo yofananira ndi 5.5, ndipo kuuma kwa njira yolumikizira kristalo ndi 6.5 mpaka 7, motero imatchedwa "miyala iwiri yolimba", ndipo kachulukidwe ndi 3.56 mpaka 3.68g / cm3.Zigawo zazikuluzikulu ndi kyanite ndi sillimanite pang'ono.
Makhiristo a Andalusite ndi columnar, pafupifupi masikweya mumtanda, ndipo amakonzedwa mu mawonekedwe a mtanda wokhazikika pamtanda.3.2g/cm3.
Sillimanite makhiristo ndi singano ngati singano, kawirikawiri radial ndi fibrous aggregates, imvi-bulauni kapena imvi wobiriwira, vitreous, 7 kuuma, ndi 3.23-3.27g/cm3 kachulukidwe.
Ma minerals a gulu la Kyanite amasinthidwa kukhala osakaniza a mullite (omwe amadziwikanso kuti mullite) ndi silika (cristobalite) pa calcination pa kutentha kwakukulu, ndikuwonjezera kuchuluka kwa voliyumu.Maminolo ogwirizana ndi biotite, muscovite, sericite, quartz, graphite, plagioclase, garnet, rutile, pyrite, chlorite ndi mchere wina.
Malo ogwiritsira ntchito ndi zizindikiro zaumisiri
Refractory zipangizo ndi waukulu ntchito minda ya kyanite mchere, amene angagwiritsidwe ntchito popanga njerwa, kuwongolera kutentha ntchito refractory mankhwala, synthesizing mullite pa kutentha kwambiri, ndi crystalline ndi mandala kyanite ndi andalusite angagwiritsidwe ntchito ngati miyala yamtengo wapatali kapena ntchito zamanja.
Kugwiritsa ntchito kwambiri mchere wa kyanite:
| Munda wofunsira | Ntchito yayikulu |
| Wotsutsa | Kupanga njerwa zosasunthika, kukonza njerwa zosakanizidwa ndi kutentha kwambiri, zida zomangira zosaoneka bwino |
| Zoumba | Zapamwamba Ceramics, Technical Ceramics |
| Metallurgy | Mphamvu yayikulu ya silicon aluminium alloy |
| Refractory CHIKWANGWANI | Refractory lining, spark plug lining insulator |
| mwala wamtengo wapatali | Crystal granularity, yowala komanso yowonekera ngati zopangira miyala yamtengo wapatali |
| Mankhwala | Kupanga mano opangira mano, kuphatikiza mbale zosweka za mafupa |
| Chemical | High kutentha processing mullite, asidi kusamva zakuthupi, kutentha kwambiri kuyeza chubu |
Chifukwa cha kusiyana kwa magwiridwe antchito amitundu yosiyanasiyana yamafuta opangira mchere, kugwiritsa ntchito komanso magwiridwe antchito, pali zofunikira zosiyanasiyana pamtundu wa kyanite.
Ukadaulo waukadaulo - kupindula ndi kuyeretsa
Njira yopezera phindu komanso ukadaulo wa mchere wa kyanite makamaka zimadalira mikhalidwe ya mchere, nthawi zambiri kuyandama, kulekanitsa mphamvu yokoka ndi kupatukana kwa maginito, ndi zina zambiri.
①Kuyandama
Flotation ndiye njira yayikulu yopindulira mchere wa kyanite, koma nthawi zambiri imayenera kuphatikizidwa ndi njira zina kuti zikwaniritse zofunikira zamakampani.Gravity desliming kapena kuyandama pambuyo pa kupatukana kwa maginito nthawi zambiri amagwiritsidwa ntchito.Osonkhanitsa amagwiritsa ntchito mafuta acids ndi mchere wawo, osalowerera kapena ofooka acidic zamkati PH mtengo, zomwe zimalimbikitsa kwambiri ndikupera fineness, zonyansa katundu, desliming effect, dongosolo mankhwala ndi zamkati PH mtengo.
②Sankhaninso
Kwa mchere wonyezimira komanso wosakanikirana wa kyanite, njira yolekanitsa mphamvu yokoka imagwiritsidwa ntchito kwambiri, ndipo zida zolekanitsa mphamvu yokoka zimaphatikizapo tebulo logwedezeka, chimphepo, sing'anga yolemera ndi chute yozungulira.
③Njira yolekanitsa maginito
Ndi njira yofunikira pakupindula kwa kyanite.Nthawi zambiri amagwiritsidwa ntchito pokonza zida zosankhidwa kuti abwezeretse kapena kuchotsa zinthu za maginito, kapena pokonzanso zinthu kuti achotse zonyansa monga chitsulo ndi titaniyamu ndikuwongolera kalasi.Zida zolekanitsa maginito zikuphatikizapo ng'oma maginito olekanitsa, mbale maginito olekanitsa, ofukula mphete mkulu gradient maginito olekanitsa, etc. zida maginito kulekana ndi ndondomeko otaya anatsimikiza malinga ndi mphamvu ya chidetso maginito.
Synthetic mullite
Mullite ndi chinthu chapamwamba kwambiri chokana.Pali njira ziwiri zopangira mullite kuchokera ku kyanite zopangira.Imodzi ndiyo kupanga calcine mwachindunji kupanga sing'anga-aluminium mullite clinker, ndipo ina ndikuwonjezera bauxite, alumina ndi zircon.Miyala, ndi zina zotero, imayikidwa pa kutentha kwambiri kuti ipange mullite kapena zircon mullite clinker.
