Mipira Yopera ya Alumina
Mafotokozedwe Akatundu
Mipira yopukusira ya Alumina,Zopangidwa ndi aluminiyamu oxide (Al₂O₃) ngati gawo lawo lalikulu ndipo pogwiritsa ntchito njira yopangira sintering ya ceramic, ndi mipira ya ceramic yogwira ntchito yomwe imapangidwira kupyola, kuphwanya, ndi kufalitsa zinthu. Ndi imodzi mwa njira zopukusira zomwe zimagwiritsidwa ntchito kwambiri popukusira mafakitale (monga ziwiya zadothi, zokutira, ndi mchere).
Mipira yopukusira ya alumina imagawidwa m'magulu atatu malinga ndi kuchuluka kwa alumina m'magulu: mipira ya aluminiyamu yapakati (60%-65%), mipira ya aluminiyamu yapakati (75%-80%), ndi mipira ya aluminiyamu yapamwamba (kupitirira 90%). Mipira ya aluminiyamu yapamwamba imagawidwanso m'magulu a 90-ceramic, 92-ceramic, 95-ceramic, ndi 99-ceramic, ndipo 92-ceramic ndiyo imagwiritsidwa ntchito kwambiri chifukwa cha magwiridwe ake apamwamba. Mipira yopukusira iyi ili ndi kuuma kwakukulu (kuuma kwa Mohs kwa 9), kukhuthala kwakukulu (kupitirira 3.6g/cm³), kukana kuwonongeka ndi dzimbiri, komanso kukana kutentha kwambiri (1600°C), zomwe zimapangitsa kuti ikhale yoyenera kupukusira glazes za ceramic, zinthu zopangira mankhwala, ndi mchere wachitsulo.
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.

Mbiri Yakampani
Shandong Robert New Material Co., Ltd.ili ku Zibo City, Shandong Province, China, komwe ndi malo opangira zinthu zopinga. Ndife kampani yamakono yomwe imagwirizanitsa kafukufuku ndi chitukuko, kupanga, kugulitsa, kapangidwe ndi zomangamanga za uvuni, ukadaulo, ndi kutumiza zinthu zopinga. Tili ndi zida zonse, ukadaulo wapamwamba, mphamvu yaukadaulo yamphamvu, khalidwe labwino kwambiri la malonda, komanso mbiri yabwino. Fakitale yathu imakwirira maekala opitilira 200 ndipo kutulutsa kwapachaka kwa zinthu zopinga ndi pafupifupi matani 30000 ndipo zinthu zopinga ndi matani 12000.
Zinthu zathu zazikulu zopangidwa ndi zinthu zotsutsa ndi izi:zipangizo zotsukira za alkaline; zipangizo zotsukira za silikoni ya aluminiyamu; zipangizo zosaoneka ngati zotsukira; zipangizo zotenthetsera kutentha; zipangizo zapadera zotsukira; zipangizo zogwirira ntchito zotsukira za makina opitira patsogolo.
Mafunso Ofunsidwa Kawirikawiri
Mukufuna thandizo? Onetsetsani kuti mwapita ku malo athu othandizira kuti mupeze mayankho a mafunso anu!
Ndife opanga enieni, fakitale yathu yakhala ikupanga zinthu zotsutsa kwa zaka zoposa 30. Tikulonjeza kupereka mtengo wabwino kwambiri, ntchito yabwino kwambiri yogulitsa zinthu zisanagulitsidwe komanso zitagulitsidwa.
Pa njira iliyonse yopangira, RBT ili ndi dongosolo lathunthu la QC la kapangidwe ka mankhwala ndi mawonekedwe ake. Ndipo tidzayesa katunduyo, ndipo satifiketi yaubwino idzatumizidwa ndi katunduyo. Ngati muli ndi zofunikira zapadera, tidzayesetsa momwe tingathere kuti zigwirizane nazo.
Kutengera kuchuluka kwa katundu, nthawi yathu yotumizira ndi yosiyana. Koma tikulonjeza kutumiza mwachangu momwe tingathere ndi mtundu wotsimikizika.
Inde, timapereka zitsanzo zaulere.
Inde, ndithudi, mwalandiridwa kupita ku kampani ya RBT ndi zinthu zathu.
Palibe malire, titha kupereka malingaliro abwino kwambiri komanso yankho malinga ndi momwe zinthu zilili.
Takhala tikupanga zinthu zopinga kwa zaka zoposa 30, tili ndi chithandizo champhamvu chaukadaulo komanso chidziwitso chambiri, titha kuthandiza makasitomala kupanga ma uvuni osiyanasiyana ndikupereka chithandizo chimodzi chokha.
