Mchere wa Kyanite umaphatikizapo kyanite, andalusite, ndi sillimanite. Zitatuzi ndi zosiyana 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 aluminiyamu-silicon ndi ulusi wotsutsa.

Katundu wa Ore ndi Kapangidwe ka Mineral

Makatani a Kyanite ndi apilala, buluu kapena buluu-imvi, vitreous ndi ngale. Kuuma 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 a columnar, pafupifupi masikweya pamtanda, ndipo amakonzedwa mwanjira yokhazikika 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

Zipangizo zokanira ndiye minda yayikulu yogwiritsira ntchito mchere wa kyanite, womwe ungagwiritsidwe ntchito popanga njerwa, kuwongolera kutentha kwambiri kwa zinthu zotsutsana, kupanga mullite pakutentha kwambiri, ndipo kyanite yoyera komanso yowoneka bwino ya kyanite ndi andalusite zitha kugwiritsidwa ntchito ngati miyala yamtengo wapatali kapena ntchito zamanja.

Kugwiritsa ntchito kwambiri mchere wa kyanite:

Malo ogwiritsira ntchito 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 kwa 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 ndi kuchuluka kwa njira zogwiritsira ntchito, pali zofunikira zosiyanasiyana pamtundu wa kyanite.

Ukadaulo wokonza - kupindula ndi kuyeretsa

Njira yopezera phindu komanso ukadaulo wa mchere wa kyanite makamaka zimadalira mikhalidwe yomwe ili ndi 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 imafunika 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 zopangira zosankhidwa kuti zibwezeretse kapena kuchotsa zinthu za maginito, kapena kukonzanso zinthu kuti zichotse 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. The 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 zambiri, imayikidwa pa kutentha kwambiri kuti ipange mullite kapena zircon mullite clinker.
