Ipuleti Elivunguziwe Le-Alumina Ceramic Elimelana Nokugqokwa: Ingxenye Eyinhloko Yokuthuthukisa Ukusebenza Kokugqokwa Kwezimboni

Ipuleti le-aluminium ceramic elivikelwe yi-ceramic elingagugiiyinto ehlanganisiwe esebenzayo eyenziwe ngokubopha i-alumina ceramic ehlanzekile kakhulu (okuqukethwe kwe-Al₂O₃ ≥92%) ne-raber matrix ngenqubo yokushisa eshisayo. Ihlanganisa ubulukhuni obukhulu be-ceramic kanye nomthamo werabha wokubopha onwebekayo, okwenza ifanelekele ukuvikelwa kobuso bemishini yezimboni ngaphansi kwezimo ezithinta kakhulu nezigugile kakhulu. Ubulukhuni obujwayelekile bengqimba ye-alumina ceramic bufinyelela ku-HRA 85-90, ubuningi busukela ku-3.6 kuya ku-3.9 g/cm³, futhi ukumelana kwayo nokugugile cishe kuphindwe izikhathi eziyi-10 kuya kweziyi-15 kunokwamapuleti ensimbi avamile.

Imininingwane ebalulekile yokusebenza ifaka: ubukhulu bethayela le-ceramic ngokuvamile buyi-15-30 mm, ubukhulu bengqimba yerabha buyi-4-15 mm, kanye namandla okuqhekeka aphelele ≥12 kN/m. Izinga lokushisa lokusebenza lisukela ku--40°C kuya ku-+120°C, kanye nokubekezelelana kwesikhashana okufika ku-150°C. I-coefficient of friction ingaphansi kuka-0.2, okunciphisa ngempumelelo ukunamathela kwezinto kanye nezingozi zokuvaleka ngesikhathi sokuhambisa. Ngenqubo ye-vulcanization, ukuxhumanisa kwamakhemikhali esibonakalayo se-ceramic-raber kuvimbela ukuhlukaniswa noma ukwahlukana, kwandisa impilo yenkonzo ngeminyaka emi-3-5 uma kuqhathaniswa nama-liners ensimbi ajwayelekile e-manganese.

Izicelo eziyinhloko zifaka: izindawo zokudlulisa amabhande okuhambisa, ama-chute, nama-hopper ezimbonini zezimayini kanye nezimboni ezihlanganisiwe; ama-chute okuphakelayo kanye nezindawo zokuhlukanisa ezitshalweni zensimbi nezesimende; kanye namashubhu okulahla amalahle ezinhlelweni zokuphatha amalahle ezitshalo zamandla. Ngesikhathi sokufakwa, ipuleti elihlanganisiwe linamathele epuletini lesisekelo semishini nge-cold bonding noma i-hot vulcanization, ngaphandle kwezinamathiselo eziyinkimbinkimbi zemishini. Ezindaweni ezigugile kakhulu, kungakhethwa ifomula ehlanganisiwe ye-zirconia-toughened (Al₂O₃-ZrO₂) ekhulisa ukuqina kokuqhekeka kube ngu-4.5-5.5 MPa·m¹/², okuvimbela ukulimala komthelela okuvela ezintweni ezinkulu.
