M'munda wa zida zotsutsa, corundum, monga chinthu chofunikira kwambiri, chakhala chogwiritsidwa ntchito kwambiri mumakampani okanira chifukwa champhamvu zake zakuthupi ndi zamankhwala. Nkhaniyi ifotokoza za mawonekedwe oyambira, kugwiritsa ntchito mokulirapo, momwe msika uliri, komanso kupanga kwa corundum mwatsatanetsatane, ndikuyang'ana kwambiri makina opera a 200-mesh corundum apamwamba kuti akuwululireni momwe amatsogolera nyengo yatsopano yogaya bwino.

Corundum ndi mwala wopangidwa ndi crystallization ya aluminium oxide. Kuuma kwake ndi kwachiwiri kwa diamondi ndi cubic boron nitride, ndipo kuuma kwake kwa Mohs kumafika 9. Dzina la corundum linachokera ku India. Chigawo chake chachikulu ndi Al₂O₃, ndipo pali mitundu itatu: α-Al₂O₃、β-Al₂O₃、γ-Al₂O₃. Chifukwa cha mawonekedwe ake abwino kwambiri, corundum imagwiritsidwa ntchito kwambiri pazinthu zopeka zapamwamba, mawotchi, zonyamula zida zamakina olondola, ndi magawo ena.

Kugwiritsa ntchito corundum

Mitundu yogwiritsira ntchito corundum ndi yotakata kwambiri, yogwira ntchito zambiri zamafakitale monga zitsulo, makina, makampani opanga mankhwala, zamagetsi, ndege, ndi chitetezo cha dziko. Chifukwa cha kukana kwake kutentha kwambiri, kukana kwa dzimbiri, ndi mphamvu zambiri, corundum imagwiritsidwa ntchito ngati crucible ndi chotengera choponyera zitseko zokhotakhota zachitsulo, kusungunula zitsulo zamtengo wapatali, ndi ma alloys apadera; m'machitidwe amankhwala, corundum imagwiritsidwa ntchito ngati ziwiya zosiyanasiyana zamapaipi ndi mapaipi ndi zida zapampopi zamankhwala; m'munda wamakina, corundum imagwiritsidwa ntchito popanga mipeni, nkhungu, zida zoteteza zipolopolo, ndi zina zambiri. Kuphatikiza apo, zinthu zowoneka bwino za corundum zitha kugwiritsidwanso ntchito kupanga nyali ndi ma microwave fairings, ndipo Na-b-Al₂O₃ zopangidwa ndi zinthu za electrolyte zopangira mabatire a sodium-sulfure.

Corundum Market Situation

M'zaka zaposachedwa, ndikupita patsogolo kwa sayansi ndi ukadaulo komanso kukula kwachangu kwamakampani, kufunikira kwa corundum kukupitilira kukula, ndipo chiyembekezo chamsika ndi chachikulu. China, India, ndi Brazil ndi omwe amapanga kwambiri corundum padziko lonse lapansi, ndipo dziko la China ndilomwe limapanga komanso kutumiza kunja kwa corundum yoyera. Msika wa corundum umapereka chiwongolero choyambira pakati pa kupezeka ndi kufunikira, pomwe mtundu wazinthu ukuyenda bwino komanso malo ogwiritsira ntchito akukulirakulirabe. Makamaka m'magawo apamwamba monga kupukuta ndi kupukuta mwatsatanetsatane, kugwiritsa ntchito corundum kukukulirakulira.

Njira yopanga corundum

Njira yopangira corundum imaphatikizapo njira zingapo monga kukonzekera zinthu, kusungunula, kuzizira, crystallization ndi processing. Choyamba, ufa wapamwamba wa aluminiyumu wa oxide umawunikidwa ndikuwumitsa kuti utsimikizire kufanana ndi chiyero cha zipangizo. Kenako, ufa wa aluminium oxide umayikidwa mu ng'anjo yamagetsi ndikutenthedwa mpaka kutentha kwambiri kuti usungunuke kukhala madzi. M'malo osungunuka, mamolekyu a aluminium oxide amadzikonzanso kuti apange mawonekedwe a kristalo ndikupanga tinthu tating'onoting'ono ta corundum. Kenako, kutentha kumatsitsidwa pang'onopang'ono kuti tinthu tating'onoting'ono ta corundum tikhazikike pang'onopang'ono kukhala cholimba. Pomaliza, imatenthedwanso kuti mawonekedwe a kristalo akhale okhazikika ndikuwongolera kuuma ndi kuvala kukana kwa corundum.

Kuyambitsa makina 200 a mesh corundum apamwamba kwambiri akupera

Corundum ikagwiritsidwa ntchito m'magawo ena, imayenera kupedwa kukhala ufa wabwino wa 200-mesh, monga zopangira zitsulo, zida zamagalasi za ceramic, ndi zida za semiconductor optical. Chinthu choyamba nthawi zambiri ndi kugaya. Panthawiyi, muyenera kugwiritsa ntchito makina opera a 200-mesh corundum apamwamba kwambiri. Guilin Hongcheng ndi zida zoweta zapamwamba zazikulu za R&D ndi bizinesi yopanga. Mphero ya pendulum ya HC yomwe idapangidwa ndi yabwino kwa makina opera a 200-mesh corundum apamwamba kwambiri.

Makina osambira a HC akupezeka m'mitundu yosiyanasiyana, zotuluka paola lililonse kuyambira tani 1 mpaka matani 50. Zipangizozi zimakhala zokhazikika zikayamba, makina oponderezedwa olakwika amakhala ndi chisindikizo chabwino, malo ochitira misonkhano ndi aukhondo, kukonza tsiku ndi tsiku ndikosavuta, ndipo mtengo wogwirira ntchito ndi kukonza ndi wotsika. Amagwiritsidwa ntchito kwambiri m'makampani a refractory ndipo ali ndi ntchito zambiri.

Guilin Hongcheng 200 mauna corundum mkulu-mwachangu akupera makina pang'onopang'ono kukhala zida zofunika m'munda wa mchere processing ndi kukonzekera zinthu chifukwa dzuwa mkulu, kupulumutsa mphamvu ndi kuteteza chilengedwe. Monga zida zapamwamba kwambiri, kufunikira kwa msika wa corundum kukupitilira kukula ndipo chiyembekezo chamsika ndi chachikulu. Takulandirani kuti mutiuze za mawu atsopano.
