Chiyambi, kugwiritsa ntchito ndi kupanga njira ya white corundum
Alumina Yoyera Yophatikizidwa (WFA)Ndi chinthu chopangidwa ndi ufa wa alumina wa mafakitale ngati chinthu chachikulu chopangira zinthu, chomwe chimaziziritsidwa ndi kusungunuka pambuyo pa kusungunuka kwa arc kutentha kwambiri. Gawo lake lalikulu ndi aluminiyamu oxide (Al₂O₃), yokhala ndi chiyero choposa 99%. Ndi yoyera, yolimba, yokhuthala, ndipo ili ndi kukana kutentha kwambiri, kukana dzimbiri komanso kutenthetsa. Ndi imodzi mwa zinthu zodziwika bwino kwambiri zogwiritsa ntchito kwambiri.
1. Chiyambi cha Zamalonda
Corundum yoyera ndi mtundu wa corundum yopangidwa. Poyerekeza ndi corundum yofiirira, ili ndi zinthu zochepa zodetsedwa, kuuma kwambiri, mtundu woyera, yopanda silika, ndipo siivulaza thupi la munthu. Ndi yoyenera kwambiri pazochitika zogwirira ntchito zomwe zimafunikira kwambiri kuti ikhale yoyera, mtundu ndi magwiridwe antchito opera. Corundum yoyera ili ndi kuuma kwa Mohs mpaka 9.0, yachiwiri pambuyo pa diamondi ndi silicon carbide. Ili ndi mphamvu zabwino zodzinola, sizovuta kumamatira pamwamba pa ntchito yopera, ndipo imataya kutentha mwachangu. Ndi yoyenera njira zonse ziwiri zouma komanso zonyowa.
2. Mapulogalamu Aakulu
Chifukwa cha mphamvu zake zapadera zakuthupi ndi zamakemikolo, corundum yoyera imagwiritsidwa ntchito kwambiri m'magawo ambiri apamwamba, kuphatikiza koma osati kokha pazinthu izi:
Zida zopukutira ndi zopukutira
Amagwiritsidwa ntchito popanga mawilo opukutira a ceramic, mawilo opukutira a resin, nsalu ya emery, sandpaper, ma scouring pads, ma grinding pastes, ndi zina zotero. Ndi chinthu chabwino kwambiri chopukutira chachitsulo chokhala ndi mpweya wambiri, chitsulo chosungunuka, chitsulo chosapanga dzimbiri, galasi, ma ceramic ndi zinthu zina.
Kupukuta ndi kupukuta mchenga
Ndi yoyenera kuyeretsa pamwamba pa chitsulo, kuchotsa dzimbiri, kulimbitsa pamwamba komanso kuchiza matte. Chifukwa cha kuuma kwake kwambiri komanso kosaopsa komanso kopanda vuto, nthawi zambiri imagwiritsidwa ntchito popukuta ndi kupukuta nkhungu zolondola komanso zinthu zosapanga dzimbiri.
Zipangizo zopopera mpweya
Itha kugwiritsidwa ntchito ngati ufa wosakaniza kapena wosalala wa njerwa zapamwamba zosasunthika, zinthu zotayidwa, ndi zinthu zotayidwa. Imagwiritsidwa ntchito kwambiri m'malo otentha kwambiri monga chitsulo, ziwiya zosungunulira zitsulo zosapanga chitsulo, ma uvuni agalasi, ndi zina zotero.
Makampani amagetsi/owonera
Amagwiritsidwa ntchito popanga zinthu zoyeretsera zadothi zoyera kwambiri, kupukutira magalasi owoneka bwino, kupukuta kwa LED, kutsuka ndi kupukuta mawaya a silicon wafer, ndi zina zotero, komanso ufa woyera wa corundum woyera kwambiri umafunika.
Chodzaza chogwira ntchito
Amagwiritsidwa ntchito mu rabara, pulasitiki, zokutira, ceramic glaze ndi mafakitale ena kuti awonjezere kukana kuwonongeka, kukhazikika kwa kutentha komanso magwiridwe antchito a zinthu zotetezera kutentha.
3. Njira yopangira
Njira yopangira corundum yoyera ndi yovuta komanso yasayansi, makamaka kuphatikiza masitepe ofunikira awa:
Kukonzekera zinthu zopangira
Sankhani ufa wa alumina wa mafakitale woyeretsedwa kwambiri (Al₂O₃≥99%), yesani ndi kuyesa zipangizozo ndi mankhwala kuti muwonetsetse kuti kuchuluka kwa zinyalala kuli kochepa kwambiri komanso kukula kwa tinthu tating'onoting'ono ndi kofanana.
Kusungunuka kwa Arc
Ikani ufa wa alumina mu uvuni wa arc wa magawo atatu ndikuusungunula pa kutentha kwakukulu kwa pafupifupi 2000℃. Panthawi yosungunula, ma electrode amatenthedwa kuti asungunuke alumina kwathunthu ndikuchotsa zonyansa kuti apange kusungunuka kwa corundum koyera.
Kuzizira kwa kristalo
Pambuyo poti kusungunuka kwazizira, kumapanga makristalo oyera a corundum. Kuzizira pang'onopang'ono kumathandiza kuti tirigu azikula bwino komanso kuti ntchito yake ikhale yokhazikika, zomwe ndi njira yofunika kwambiri yotsimikizira kuti corundum yoyera ndi yabwino.
Kuphwanya ndi kulekanitsa maginito
Ma kristalo a corundum ozizira amaphwanyidwa ndi kuphwanyidwa bwino ndi zida zamakina, kenako zinthu zodetsedwa monga chitsulo zimachotsedwa ndi kulekanitsidwa kwamphamvu kwa maginito kuti zitsimikizire kuti chinthu chomalizidwa chili choyera.
Kuphwanya ndi kusanthula
Gwiritsani ntchito mipiringidzo ya mpira, mipiringidzo yoyendera mpweya ndi zida zina kuti muphwanye corundum yoyera kufika pa kukula kwa tinthu tofunikira, kenako gwiritsani ntchito zida zowunikira bwino kwambiri kuti muyese kukula kwa tinthuto molingana ndi miyezo yapadziko lonse lapansi (monga FEPA, JIS) kuti mupeze mchenga kapena ufa wochepa wamitundu yosiyanasiyana.
Kukonza bwino ndi kuyeretsa (kutengera cholinga chake)
Pa ntchito zina zapamwamba, monga ufa wa corundum woyera wamagetsi ndi wamagetsi, kugawa mpweya, pickling ndi kuyeretsa kwa ultrasound kumachitika kuti ziwongolere kuyera ndi kulondola kwa kukula kwa tinthu.
Kuyang'anira ndi kulongedza bwino
Chogulitsa chomalizidwacho chiyenera kuchitidwa zinthu zingapo zowongolera khalidwe monga kusanthula mankhwala (Al₂O₃, Fe₂O₃, Na₂O, ndi zina zotero), kuzindikira kukula kwa tinthu, kuzindikira kuyera, ndi zina zotero, ndipo chikadutsa mayesowo, chimapakidwa malinga ndi zosowa za makasitomala, nthawi zambiri m'matumba a 25kg kapena matumba a tani.
Monga zipangizo zamafakitale zomwe zimagwira ntchito bwino kwambiri, corundum yoyera imagwira ntchito yofunika kwambiri m'mafakitale ambiri. Sikuti imangoyimira zinthu zapamwamba zokha, komanso ndi chinthu chofunikira kwambiri m'magawo apamwamba monga makina olondola, ziwiya zogwirira ntchito, ndi zipangizo zamagetsi. Ndi chitukuko chopitilira chaukadaulo wamafakitale, zofunikira pamsika wa corundum yoyera zikupitilirabe kukwera, zomwe zimapangitsanso opanga kuti azikonza njira zawo nthawi zonse, akonze magwiridwe antchito azinthu, ndikupanga njira yoyera kwambiri, kukula kwa tinthu tating'onoting'ono, komanso mtundu wokhazikika.
