Ndeupi musiyano uripo pakati pecorundum mullite zvidhinha uye yakakwirira alumina zvidhinha?

Musiyano mukuru pakati pecorundum mullite zvidhinha uye yakakwirira alumina zvidhinha ndiyo chikamu chekristaro, uye chitarisiko uye ruvara rwakati siyana. Chikonzero chikuru chiyero chezvigadzirwa. Ndapota ona sumo yakadzama pazasi.

Corundum mullite chidhinha

Iine simba rakanaka rekushisa kwepamusoro, tembiricha yekukwira inokwira, kupisa kwekushisa kwekudzivirira uye kusagadzikana kwecorrosion. Iyo yemuviri uye yemakemikari zvimiro zveyakajairwa corundum mullite zvidhinha ndeye Al2O3> 85%, Fe2O30.45%, inooneka porosity 19%, yakajairika tembiricha inomanikidza simba 55MPa, mutoro unonyorovesa tembiricha pamusoro pe1700 ℃, mutsara wekudziya shanduko (1600 ℃, 3h) -0.1 %.

Yakakwirira alumina zvidhinha

Zviri mukati mealuminium oxide ndeye 48% kusvika 85%, iyo inogona kukamurwa kuva yakakosha, yepuraimari, yechipiri, yepamusoro, nezvimwe. Fe2O30.45%, inooneka porosity i19%, simba rekumanikidza pakupisa kwekamuri rinopfuura 55MPa, tembiricha yekunyorovesa inodarika 1700 ℃, kupisa waya shanduko (1600 ℃, 3h) -0.1%, kupisa kutyisa kuramba (1100 ℃ kutonhora kwemvura) kanopfuura makumi matatu. Chigadzirwa chacho chinoshandisa high-aluminium alum clinker sechinhu chikuru mbishi, ivhu rakapfava uye tsvina pulp uye pepa remvura sechinhu chinosunga, uye madhaka ane ma-multi-stage particles anoumbwa ne-high-pressure molding, kuomesa uye kupisa kwepamusoro-kupisa.
