Isitena esidityanisiweyo
Isitena esidityanisiweyo
Izibonelelo zeMveliso: ubushushu obuqhelekileyo obuphezulu bokuqina (ukuya kuthi ga kwi-340MPa), ubushushu obuphezulu bokuthambisa ubushushu (ubushushu bokuqala bokuthamba bungaphezulu kwe-1700 ° C), uzinzo lweekhemikhali olulungileyo, i-asidi elungileyo kunye ne-alkali slag, intsimbi etyhidiweyo kunye neglasi yokumelana.
Isicelo seMveliso: Ezona zinto zisetyenziswayo kwizitena ze-und-β corundum izitena ezisetyenziswa kakhulu Icandelo lokucacisa, icandelo lokupholisa, iphuli yokusebenza, njl njl. Ukongeza, izitena ezihlanganisiweyo ze-α-β corundum ziyasetyenziswa nakwisilingi nakwisakhiwo esingaphezulu seefestile zeglasi. Izitena ze-beta corundum ezisetyenzisiweyo zinokusetyenziselwa kuphela ukwakheka okuphezulu kwesitovu seglasi ngothuli lwe-SO2, njengakwisakhiwo esiphezulu sedama elisebenzayo, udonga lwebele kufutshane nesitshisi, isitshisi somlilo omncinci, udonga oluxhonywe njalo njalo .
Ingcaciso yeMveliso
Isigaba esiphambili sekristal yesitena esidityanisiweyo se-corundum yi-corundum, kwaye umxholo we-Al2O3 ngokubanzi uphezulu kune-93%. Ukuxhathisa kukothuka kwe-thermal kwezitena ezihlanganisiweyo ze-corundum kunxulumene kakhulu nomzimba. Ukuxinana kweemveliso zecorundum kunokumelana ngcono nokubola, kodwa ukuxhathisa okungathathi ntweni kwe-thermal. Izitena ze-corundum ezidityanisiweyo zingahlulwa-hlulwa zibe zizitena ezihlanganisiweyo, izitena ezi-α-β zekorundum kunye nezitena ezihlanganisiweyo.
Iimpawu zezitena ezihlanganisiweyo ze-corundum:
1.Ukucinezelwa okuphezulu kwamandla kubushushu begumbi (ukuya kuthi ga kwi-340MPa)
Ubushushu obuthambisa umthwalo ophezulu (ubushushu bokuqala bokuthamba bungaphezulu kwe-2 ℃)
3. Uzinzo lweekhemikhali olulungileyo
4. Ukumelana kakuhle ne-asidi kunye ne-alkali slag, isinyithi esinyibilikisiweyo kunye neglasi
