Reactive Alumina Ali ndi Chiyero Chapamwamba, Magawo Abwino Akukula Kwa Tinthu Ndi Ntchito Yabwino Kwambiri Yopangira Sintering

Alumina yoyendetsedwa
adamulowetsa aluminium okusayidi
Ufa wokhazikika wa aluminiyamu

Kufotokozera Kwachidule

Ma aluminiyamu osunthika amapangidwa mwapadera kuti apange ma refractories apamwamba kwambiri pomwe kulongosoledwa kwa tinthu tating'onoting'ono, ma rheology ndi mawonekedwe osasunthika ndikofunika kwambiri ngati mawonekedwe apamwamba kwambiri a chinthu chomaliza. Ma aluminiyamu osunthika amatsitsidwa mpaka makhiristo oyambira (amodzi) ndi njira zabwino kwambiri zogaya. Kukula kwa tinthu tating'ono, D50, kwa ma alumina a mono-modal reactive, motero kumakhala kofanana ndi kukula kwa makhiristo awo amodzi. Kuphatikiza aluminum zotakasika ndi zigawo zina masanjidwewo, monga tabular aluminiyamu 20μm kapena spinel 20μm, amalola kulamulira tinthu kukula kugawa kukwaniritsa ankafuna masungidwe rheology.

Zogulitsa Zamalonda

Ma aluminiyamu ogwira ntchito kuchokera ku sub-micron mpaka 3 micron particle size. Kugawa kwa tinthu tating'onoting'ono, kuyambira pa mono-modal kupita ku bi-modal ndi multi-modal, kumalola kusinthasintha kwathunthu pamapangidwe apangidwe ndikupereka kusavuta kwa ma alumina opangidwa ndi injiniya opangidwa ndi makina osakanikirana.

The zotakasika alumina yaying'ono-ufa, wopangidwa mwa mwapadera sintering ndondomeko, akupera ndondomeko ndi multistage mphamvu kulekana kukula, ali ndi chiyero mkulu, wabwino particles kugawa kukula ndi ntchito yabwino sintering, amene ali oyenera ntchito kupanga mkulu ntchito refrac-tory zakuthupi. , ndi zinthu zamagetsi zadothi zamagetsi .The zotakataka alpha alumina micropowerd akhoza bwino ankalamulira tinthu kukula kugawa mu osiyanasiyana submicron, kutsogolera kukhala ndi zabwino kwambiri tirigu kulongedza katundu wabwino rheological katundu ndi khola workability komanso ntchito yabwino sintering, amene amasewera wapadera ntchito mu refractory:
1. Mwa optimizing tinthu kudzikundikira kuchepetsa Kuwonjezera kuchuluka kwa madzi
2. Kukana kuvala ndi mphamvu zamakina zimakonzedwa bwino popanga gawo lolimba la ceramic chomangira;
3. Kutentha kwapamwamba kwa mankhwalawa kumapangidwa bwino ndikusintha ufa wapamwamba kwambiri ndi kukana kochepa.

Reactive Alumina Ultrafine Yapamwamba-Ntchito Refractories

Reactive a-alumina micro-ufa atha kugwiritsidwa ntchito mu ladle castables, BF trough castables, purge plugs, seat blocks, alumina self-flow castables, ndi zosakaniza za mfuti komanso, zomwe zimapangidwanso molingana ndi miyezo ya Transnational Corporation. Ufawu uli ndi zonyansa zochepa, kugawa tinthu tating'onoting'ono ndikuchitanso bwino, zimapatsa ma castables kuyenda bwino, kuchepa kwapang'onopang'ono, nthawi yoyenera yogwirira ntchito, kapangidwe wandiweyani komanso mphamvu zabwino kwambiri, ndi
adatumizidwa ku Japan, USA, ndi Europe.

Ma aluminiyamu Ogwira Ntchito Apamwamba Ogwira Ntchito Refractories

Ma aluminiyamu osunthika mokwanira amapangidwa mwapadera kuti apange zida zapamwamba zogwirira ntchito, pomwe kulongedza tinthu tating'onoting'ono, rheology ndi mawonekedwe osasunthika ndizofunikira kwambiri monga momwe zimakhalira ndi zinthu zomaliza.

Magwiridwe Azinthu
Kugawa kwa tinthu tating'onoting'ono komwe kumayendetsedwa bwino mpaka pamitundu yaying'ono ya micron ndikuchita bwino kwambiri kwa sintering kumapereka ma Reactive Aluminas ntchito zapadera pamapangidwe a refractory.

Zofunika kwambiri ndi izi:
• Kuchepetsa kusakaniza madzi a monolithic refractories pothandiza kukhathamiritsa tinthu kulongedza katundu.
• Kuchulukitsa kukana kwa abrasion ndi mphamvu zamakina popanga zomangira zolimba za ceramic.
• Kuonjezera kutentha makina ntchito ndi m'malo mwa superfine zipangizo oflower refractoriness.

Kulongedza:
25KG / thumba, 1000kg / thumba kapena kulongedza ena enieni malinga ndi zofunika wosuta.
