Magawo ogwiritsira ntchito ndi ubwino wa mchenga wa brown corundum
Mchenga wa corundum wofiirira, yomwe imadziwikanso kuti brown corundum kapenacorundum yofiirira yosakanikirana, ndi mtundu wa chopangira chopangira chopangidwa ndi bauxite yapamwamba kwambiri ngati chinthu chachikulu chopangira, chosungunuka ndi kuzizira pa kutentha kwakukulu kopitilira 2000℃ mu uvuni wamagetsi. Gawo lalikulu ndi aluminiyamu oxide (Al₂O₃), ndipo nthawi zambiri zimakhala zopitilira 95%. Chifukwa cha kuuma kwake kwakukulu, kulimba bwino, kukana kuvala mwamphamvu komanso kukana kutentha kwambiri, chimagwiritsidwa ntchito kwambiri m'mafakitale ambiri. Ndi kusintha kosalekeza kwa zofunikira pakukonza zinthu molondola, kugwiritsa ntchito mchenga wa brown corundum mu zopopera, zinthu zotsutsa, kukonza pamwamba, kuponyera ndi zodzaza zogwira ntchito kukukhala kofunika kwambiri.
1. Kugwiritsa ntchito kwambiri mu abrasives
Ma abrasives ndi amodzi mwa malo odziwika bwino komanso ofunikira kwambiri ogwiritsira ntchito corundum ya bulauni. Chifukwa cha kuuma kwake kwa Mohs mpaka 9.0, yachiwiri pambuyo pa diamondi ndi silicon carbide, corundum ya bulauni imagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zokwawa, monga mawilo opukusira, nsalu ya emery, sandpaper, miyala yamafuta ndi mitu yopukusira. Kaya mu kukonza zitsulo, kupukuta magalasi kapena kupukusira kwa ceramic, corundum ya bulauni imatha kupereka mphamvu yodulira bwino komanso kukana kuvala bwino. Makamaka m'mafakitale omwe amafunikira kudula mwamphamvu komanso kusunga mawonekedwe okhazikika, ma abrasives a brown corundum amagwira ntchito bwino kwambiri.
2. Monga chinthu chofunikira kwambiri popanga zinthu zotsutsana ndi chilengedwe
Corundum ya bulauni imakhala ndi kutentha kwambiri komanso kutentha kwake kumakhala kolimba, choncho imagwiritsidwa ntchito kwambiri popanga zinthu zosiyanasiyana zotsika mtengo.ng'anjo zamafakitale zotentha kwambirimonga zitsulo, chitsulo, simenti, ndi galasi, corundum yofiirira ingagwiritsidwe ntchito kupanga njerwa zapamwamba kwambiri zotsukira, zotayidwa, mapulasitiki, zipangizo zomangira ndi zinthu zina zotsukira, makamaka pazigawo zomwe zili ndi kukokoloka kwakukulu kwa kutentha komanso kutentha kwambiri. Poyerekeza ndi zipangizo zachikhalidwe zokhala ndi aluminiyamu yambiri, zipangizo zotsukira corundum yofiirira zimakhala ndi kukokoloka kwabwino kwa slag ndi kukana kuphulika, zomwe zimawonjezera nthawi yogwira ntchito ya zida ndikuchepetsa ndalama zosamalira mabizinesi.
3. Kugwiritsa ntchito mukuphulika kwa mchengandi chithandizo cha pamwamba
Mchenga wa bulauni wa corundum umagwiritsidwa ntchito kwambiri popukuta mchenga pamwamba pa chitsulo chifukwa cha kukula kwake kofanana kwa tinthu tating'onoting'ono, kuuma kwake kwakukulu komanso mphamvu yake yokoka kwambiri. Panthawi yopukuta mchenga, corundum yofiirira imatha kuchotsa dzimbiri, sikelo, utoto wakale, ndi zina zotero pamwamba pa chogwirira ntchito, ndikuwonjezera kuyera kwake komanso kumamatira pamwamba. Nthawi yomweyo, chifukwa chodzikongoletsa bwino komanso chosavuta kupumula, imatha kubwezeretsedwanso ndikugwiritsidwa ntchito mobwerezabwereza, zomwe zimachepetsa kwambiri ndalama zomwe zimagwiritsidwa ntchito. Kuphatikiza apo, corundum yofiirira imasonyezanso zotsatira zapadera pakukonza matte ndi kukonza mawonekedwe a pamwamba pa zinthu monga chitsulo chosapanga dzimbiri, ma profiles a aluminiyamu, galasi, ndi ziwiya zadothi.
4. Kugwiritsa ntchito poponya molondola
M'zaka zaposachedwapa, chifukwa cha kupita patsogolo kosalekeza kwa ukadaulo wopangira zinthu molondola, pakhala zofunikira zambiri kuti zinthu zopangira zinthu zikhale zoyera komanso zokhazikika pa kutentha.Brown corundum Chakhala chida chabwino kwambiri chopangira zinthu zolondola monga zitsulo zotentha kwambiri, chitsulo chosapanga dzimbiri, ndi chitsulo cha kaboni chifukwa cha kapangidwe kake ka mankhwala kokhazikika, kutentha koyenera, komanso kutentha kochepa. Mchenga wopaka wa corundum wofiirira ukhoza kupititsa patsogolo bwino mawonekedwe a zinthu zopaka ndikuchepetsa zolakwika zopaka. Umagwiritsidwa ntchito kwambiri m'magawo opanga zinthu zapamwamba monga ndege, magalimoto, ndi mphamvu.
5. Kugwiritsa ntchito nthawi yayitali ngati chodzaza chogwira ntchito
Corundum yofiirira ingagwiritsidwenso ntchito ngati chogwirira ntchito pazinthu monga pansi yosaterera, mipanda yosatha, ma mortar a resin, ndi zipangizo zomangira zapamwamba. Kuuma kwake kwabwino komanso kukana kupsinjika kumathandiza kukonza kukana kwa kuwonongeka ndi moyo wautumiki wa zipangizo zophatikizika. M'magawo a zamagetsi, zadothi, rabara, ndi zina zotero, ufa wa brown corundum micropowder nthawi zambiri umagwiritsidwanso ntchito ngati chodzaza kuti chiwonjezere kukana kutentha, kutentha, komanso mphamvu ya kapangidwe ka chinthucho.
Mapeto
Mchenga wa bulauni wa corundum umagwira ntchito yofunika kwambiri m'makampani amakono chifukwa cha makhalidwe ake abwino komanso kukhazikika kwa mankhwala. Chifukwa cha kukweza ukadaulo wazinthu ndi zosowa za mafakitale, msika wa mchenga wa bulauni wa corundum udzakhala wokulirapo ndipo udzabweretsanso mayankho ogwira mtima komanso oteteza chilengedwe m'mafakitale osiyanasiyana.
