Mipira Yopera ya Alumina
Monga chida chapamwamba kwambiri chopukusira cha ceramic, chathuMipira Yopera ya AluminaZapangidwa kuti zigwire ntchito bwino kwambiri pogaya, kuphwanya, ndi kufalitsa zinthu m'magawo osiyanasiyana a mafakitale. Zopangidwa ndi aluminiyamu oxide yoyera kwambiri (Al₂O₃) ngati gawo lalikulu komanso ukadaulo wapamwamba wa sintering wa ceramic, mipira iyi imadziwika chifukwa cha kuuma kwawo kwambiri, kukana kuwonongeka, komanso kukhazikika kwa mankhwala, zomwe zimapangitsa kuti ikhale chisankho choyamba chogwiritsira ntchito bwino komanso molondola zinthu.
1. Kugawa m'magulu malinga ndi kuchuluka kwa alumina
(1) Mipira ya Aluminiyamu Yapakatikati (60%-65% Al₂O₃):Njira yotsika mtengo yogwiritsira ntchito pogaya zinthu wamba. Yoyenera kugaya zinthu zosalimba kwambiri, monga malasha, feteleza, ndi mchere wamba. Yoyenera makasitomala omwe akufuna ntchito yabwino komanso njira zotsika mtengo.
(2) Mipira ya Aluminiyamu Yapakatikati (75%-80% Al₂O₃):Kulimba kwamphamvu kwa kutopa poyerekeza ndi mipira ya aluminiyamu yapakati. Imagwiritsidwa ntchito kwambiri popera zipangizo zopangira ceramic, zipangizo zomangira, ndi mankhwala osawononga kwambiri. Chisankho chosiyanasiyana chopera mafakitale apakatikati.
(3) Mipira Yokhala ndi Aluminiyamu Yaikulu (≥90% Al₂O₃):Maginito apamwamba kwambiri okhala ndi magwiridwe antchito apamwamba kwambiri. Amagawidwanso m'magulu ang'onoang'ono a 90-ceramic, 92-ceramic, 95-ceramic, ndi 99-ceramic. Pakati pawo, mipira ya 92-ceramic ndiyo yotchuka kwambiri chifukwa cha magwiridwe antchito abwino komanso mtengo wake, yomwe imagwiritsidwa ntchito kwambiri pogaya magalasi a ceramic, zipangizo zamagetsi, ndi zinthu zopangira mankhwala zoyera kwambiri. Mipira ya 99-ceramic, yokhala ndi alumina yambiri, idapangidwira kugaya molondola kwambiri m'mafakitale apamwamba monga semiconductor ndi aerospace.
2. Ntchito Zosinthira Makonda
Timamvetsetsa kuti makasitomala osiyanasiyana ali ndi zosowa zapadera. Kuti tikwaniritse zosowa zanu, timapereka ntchito zambiri zosintha:
Zinthu zopangidwa ndi alumina zomwe zimagwirizana ndi malo anu opukutira ndi mawonekedwe a zinthuzo.
Kukula kwapadera (kuyambira 1mm mpaka 50mm) ndi mawonekedwe (ozungulira, ozungulira, ndi zina zotero).
Chithandizo chapadera cha pamwamba pa zinthu kuti zisawonongeke kapena kuchepetsa kuipitsidwa.
Mayankho okonzera zinthu mwamakonda (kulongedza zinthu zambiri, kulongedza zinthu m'matumba, ndi zina zotero) kuti zithandize kunyamula ndi kusunga zinthu mosavuta.
Mawonekedwe:
Kulimba Kwambiri ndi Kukana Kwamphamvu Kwa Kuvala:Kulimba kwa Mohs kumafika 9 (pafupi ndi diamondi), ndi chiwopsezo chochepa cha kuwonongeka (<0.03%/1,000 maola a mitundu yoyera kwambiri). Imalimbana ndi kupunduka ndi zinyalala panthawi yopukutira kwa nthawi yayitali, zomwe zimapangitsa kuti ikhale nthawi yayitali yogwira ntchito.
Kuchuluka Kwambiri ndi Kugwira Ntchito Mwachangu Popera:Ndi kuchuluka kwa 3.6-3.9 g/cm³, imapereka mphamvu yamphamvu komanso yodula pogaya, imayeretsa zinthu mwachangu kufika pamlingo wa micron, ndipo imakhala yogwira ntchito bwino ndi 20%-30% kuposa mipira ya aluminiyamu yapakatikati ndi yotsika.
Zosadetsedwa Zochepa ndi Kukhazikika kwa Mankhwala:Mitundu yoyera kwambiri imakhala ndi zonyansa zosakwana 1% (monga Fe₂O₃), zomwe zimaletsa kuipitsidwa ndi zinthu. Zimalimbana ndi ma asidi ambiri ndi ma alkali (kupatula ma asidi amphamvu ndi ma alkali), kutentha kwambiri (kupitirira 800°C), ndipo ndizoyenera kugwiritsa ntchito njira zosiyanasiyana zopukutira.
Kukula Kosinthasintha ndi Kugwirizana:Mpirawu umapezeka m'mimba mwake kuyambira 0.3 mpaka 20 mm, ndipo ungagwiritsidwe ntchito m'makulidwe amodzi kapena osakanikirana, umagwirizana ndi ma ball mill, ma ball mill, ndi zida zina, kukwaniritsa zosowa zonse kuyambira pa kugaya kosalala mpaka kosalala.

Mapulogalamu Onse:
Mipira yathu yopukusira alumina imagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana omwe amafunikira kupukusira koyenera komanso kolondola. Magawo ofunikira ogwiritsira ntchito ndi awa:
1. Makampani Opanga Zinthu Zopangira Ceramic:Kupukutira zinthu zopangira ceramic, ma glaze, ndi ma frits.
2. Makampani Opaka & Kupaka:Kubalalitsa ndi kupukuta utoto, inki, ndi zinthu zokutira.
3. Makampani Okonza Migodi:Kupera mchere wosakhala wachitsulo (monga quartz, feldspar, kaolin) ndi mchere wachitsulo (monga chitsulo, mkuwa).
4. Makampani Opanga Mankhwala:Kupera zinthu zopangira mankhwala, zinthu zoyambitsa matenda, ndi zinthu zina zogwiritsira ntchito mankhwala.
5. Makampani Opanga Zinthu Zamagetsi ndi Zatsopano:Kupukutira kolondola kwambiri kwa ziwiya zamagetsi, zinthu za batri ya lithiamu, ndi zinthu za semiconductor.
6. Makampani Ogulitsa Zakudya ndi Mankhwala:Kupera zakudya zowonjezera, zopangira mankhwala (zogwirizana ndi zofunikira za chakudya ndi zofunikira za mankhwala).
