Kufotokozera Kwachidule

Tabular Alumina ndi chinthu choyera chomwe chimatenthedwa kwambiri - kutentha kwambiri popanda zowonjezera za MgO ndi B2O3, microstructure yake ndi yamitundu iwiri ya polycrystalline yokhala ndi makristasi akuluakulu a α - Al2O3.Tabular Alumina ili ndi ma pores ang'onoang'ono otsekedwa mu kristalo wa munthu payekha, zomwe zili ndi Al2O3 ndizoposa 99% .Chotero zimakhala ndi kukhazikika kwa voliyumu yabwino komanso kukana kutenthedwa kwa kutentha, kuyera kwakukulu ndi kukana, mphamvu zamakina kwambiri, kukana kwa abrasion motsutsana ndi slag ndi zinthu zina.

Tabular & Aggregates ena

Aggregates ndi msana wa mapangidwe refractory ndi kupereka dimensional bata kwa mankhwala refractory.The coarser tizigawo ting'onoting'ono kuwonjezera matenthedwe mantha ndi dzimbiri kukana ndi akaphatikiza chindapusa konza tinthu kukula kugawa ndi kuonjezera refractoriness wa mankhwala.

Ubwino wokhazikika wa Tabular alumina ndi zotsatira za ndondomeko ya sinter yoyendetsedwa bwino ndi kutentha kwa kutentha pamwamba pa 1800 ° C. Kugwiritsira ntchito ng'anjo zotentha kwambiri ndi teknoloji yamakono kumalola kusakanikirana kwa zipangizo zosankhidwa popanda zothandizira zomwe zingapangitse kumakhudza kwambiri kutentha katundu wa refractories.

Chifukwa cha ndondomeko ya sinter, ma aggregates amawonetsa kufanana kwa mineralogical ndi mankhwala kwa zigawo zonse.Mosiyana ndi zinthu zosakanizidwa zomwe zonyansa zimachulukana mu chindapusa, kugwiritsa ntchito sintered aggregates popanga refractory kumatsimikizira khalidwe lokhazikika komanso lodalirika.

Junsheng amapereka masanjidwe osiyanasiyana ophatikizika kuchokera kuzigawo zowoneka bwino kwambiri mpaka kukula bwino kwa <45 μm ndi <20 μm.Kuphwanyidwa ndi mphero kumatsatiridwa ndi njira zochepetsera-ironi zomwe zimapangitsa kuti chitsulo chaulere chikhale chochepa kwambiri m'magulu osiyanasiyana.

Njira Yopangira Tabular alumina

Kugwiritsa Ntchito Tabular Alumina

Tabular Alumina ndi chinthu chomwe chimasankhidwa m'mafakitale osapangidwa bwino omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana monga zitsulo, maziko, simenti, magalasi, prtrochemical, ceramic, ndi kuyatsa zinyalala.Ntchito zina zodziwika bwino zosakanizidwa ndizomwe zimagwiritsidwa ntchito pamipando yamoto ndi kusefera zitsulo.
