Alumina Akupera Mipira
Mafotokozedwe Akatundu
Alumina akupera mipira,opangidwa ndi aluminiyamu oxide (Al₂O₃) monga gawo lawo lalikulu ndikugwiritsa ntchito ceramic sintering process, ndi mipira ya ceramic yogwira ntchito yopangidwa makamaka kuti ipere, kuphwanya, ndi kubalalitsa zinthu. Ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pogaya mafakitale (monga zoumba, zokutira, ndi mchere).
Mipira yopera ya aluminiyamu imagawidwa m'magulu atatu: mipira ya aluminiyamu yapakati (60% -65%), mipira yapakati-yapamwamba kwambiri (75% -80%), ndi mipira ya aluminiyamu (yoposa 90%). Mipira ya aluminiyamu yapamwamba imagawidwanso kukhala 90-ceramic, 92-ceramic, 95-ceramic, ndi 99-ceramic grade, ndi 92-ceramic yomwe imagwiritsidwa ntchito kwambiri chifukwa cha ntchito yake yabwino kwambiri. Mipira yoperayi imakhala yolimba kwambiri (kulimba kwa Mohs 9), kachulukidwe kakang'ono (kupitilira 3.6g/cm³), kusavala ndi dzimbiri, komanso kukana kutentha kwambiri (1600 ° C), kuwapangitsa kukhala oyenera kukupera bwino kwa magalasi a ceramic, zopangira mankhwala, ndi mchere wachitsulo.
Mawonekedwe:
Kuuma Kwambiri ndi Kukaniza Kuvala Kwamphamvu:Kuuma kwa Mohs kumafika ku 9 (pafupi ndi diamondi), ndi kuvala kochepa kwambiri (<0.03% / 1,000 maola kwa zitsanzo zapamwamba). Imatsutsana ndi brittleness ndi zinyalala panthawi yopera kwa nthawi yayitali, zomwe zimapangitsa moyo wautali wautumiki.
Kuchulukana Kwambiri ndi Kugaya Kwambiri Mwachangu:Ndi kachulukidwe kochulukira kwa 3.6-3.9 g/cm³, imapereka mphamvu yamphamvu komanso kumeta ubweya pakagayidwe, kuyenga mwachangu zida mpaka mulingo wa micron, ndikuchita bwino kwa 20% -30% kuposa mipira ya aluminiyamu yapakati komanso yotsika.
Zowonongeka Zochepa ndi Kukhazikika kwa Chemical:Mitundu yoyera kwambiri imakhala ndi zonyansa zosakwana 1% (monga Fe₂O₃), zomwe zimalepheretsa kuipitsidwa kwa zinthu. Kugonjetsedwa ndi ma acid ambiri ndi alkalis (kupatulapo ma acid amphamvu kwambiri ndi alkalis), kutentha kwambiri (kupitirira 800 ° C), komanso koyenera ku machitidwe osiyanasiyana opera.
Makulidwe Osinthika ndi Kugwirizana:Amapezeka m'ma diameter kuchokera ku 0,3 mpaka 20 mm, mpirawo ukhoza kugwiritsidwa ntchito mosiyanasiyana kapena mosakanikirana, umagwirizana ndi mphero za mpira, mphero zamchenga, ndi zipangizo zina, kukwaniritsa zosowa zonse kuchokera ku coarse mpaka kupukuta bwino.

Mbiri Yakampani
Malingaliro a kampani Shandong Robert New Material Co., Ltd.ili mu Zibo City, Province Shandong, China, amene ndi refractory zinthu kupanga m'munsi. Ndife makampani amakono omwe amaphatikiza kafukufuku ndi chitukuko, kupanga, kugulitsa, kapangidwe ka ng'anjo ndi zomangamanga, ukadaulo, ndi zida zotumizira kunja. Tili ndi zida zonse, ukadaulo wapamwamba, mphamvu zolimba zaukadaulo, mtundu wabwino kwambiri wazinthu, komanso mbiri yabwino. Fakitale yathu imakhala ndi maekala opitilira 200 ndipo zotulutsa zowoneka bwino zowoneka bwino zimakhala pafupifupi matani 30000 ndipo zida zosapanga dzimbiri ndi matani 12000.
Zogulitsa zathu zazikulu za zida za refractory ndi:zinthu zamchere refractory; zotayidwa silicon refractory zipangizo; zinthu zosapanganika zokanira; kutchinjiriza matenthedwe refractory zipangizo; zida zapadera zokanira; zinchito refractory zipangizo mosalekeza kuponya kachitidwe.
Mafunso Ofunsidwa Kawirikawiri
Mukufuna thandizo? Onetsetsani kuti mwayendera mabwalo athu othandizira kuti mupeze mayankho a mafunso anu!
Ndife opanga zenizeni, fakitale yathu ndi yapadera popanga zida zokanira kwa zaka zopitilira 30. Timalonjeza kupereka mtengo wabwino kwambiri, ntchito yabwino kwambiri yogulitsiratu komanso yogulitsa pambuyo pake.
Panjira iliyonse yopanga, RBT ili ndi dongosolo lathunthu la QC la kapangidwe kake ndi zinthu zakuthupi. Ndipo tidzayesa katunduyo, ndipo chiphaso chabwino chidzatumizidwa ndi katunduyo. Ngati muli ndi zofunikira zapadera, tidzayesetsa kuti tikwaniritse.
Malingana ndi kuchuluka kwake, nthawi yathu yoperekera ndi yosiyana. Koma tikulonjeza kutumiza mwamsanga ndi khalidwe lotsimikizika.
Inde, timapereka zitsanzo zaulere.
Inde, ndithudi, ndinu olandiridwa kukaona RBT kampani ndi katundu wathu.
Palibe malire, titha kukupatsani malingaliro ndi yankho labwino kwambiri malinga ndi momwe mulili.
Takhala tikupanga zida zokanira kwazaka zopitilira 30, tili ndi chithandizo champhamvu chaukadaulo komanso chidziwitso cholemera, titha kuthandiza makasitomala kupanga ma kilns osiyanasiyana ndikupereka ntchito imodzi.
