PMD Series ya Zro2 gulu ceramic tundish nozzle insert

Zotsatira zoyeserera zikuwonetsa kuti dongosolo la binder la PS lili ndi mphamvu, mawonekedwe osalala mukasakanikirana ndi 125 ℃ kwa mphindi 10, ndipo silimva kutentha, komwe kuli koyenera kubaya jekeseni wa ceramic. Pachifukwa ichi, kuchuluka kwa ufa kumawonjezeka ndi 86%, Kuchepetsa zolakwika pakutha kwa degreasing ndi sintering process. Ikani chakudya chosakanikirana m'ng'anjo yamoto kuti muchepetse mphamvu, phunzirani kutentha kwa gawo lililonse la TG, ndikupanga kotsekemera koyenera kachitidwe aka. Kenaka muwotche pamatenthedwe osiyanasiyana, Malo ocheperako komanso owonera amawoneka ndi TEM. Kusintha kwa kristalo kwa zirconia ceramics kudafufuzidwa ndi XRD. Makina azitsulo zirconia zouma mosiyanasiyana kutentha adaphunziridwa. Zotsatira zake zikuwonetsa kuti zopangira ziwiya zadothi zomwe zidapangidwa mu 1550 ℃ zimakhala ndi zinthu zabwino. Zoumbaumba zopangidwa ndi alumina ndi zirconia zokhala ndi zinthu zosiyanasiyana zidasankhidwa kuti zizichotsa mafuta ndi sintering. Kapangidwe kake ndi zida zake zoumbaumba zophatikizika zidaphunziridwa ndi XRD ndi TEM, Ndipo zimatha kuchepetsa mtengo wazida zopangira.

Pamaziko a PMO1 angapo a Zro2 gulu mankhwala ceramic, kudzera mosalekeza kukhathamiritsa kwapadera ukadaulo, Fangming Chatsopano Zolemba bwino R & D, adapanga PMD mndandanda wa magwiridwe antchito apamwamba Zro2 gulu ceramic tundish nozzle insert. Ali ndi chiyero chapamwamba, kuphwanyaphwanya kwamphamvu, kukokoloka, kutentha kwamphamvu, moyo wautali. Moyo wawo wogwira ntchito umakwezedwa ndi 30-50% kutengera mtundu wa PMO1 wazogulitsa zomwezi zogwiranso ntchito.
