Ipleyiti ye-Alumina Ceramic Vulcanized Plate enganyangekiyo: Icandelo eliPhambili lokuphucula ukusebenza kweNxibo yezeMveliso

Ipleyiti ye-alumina ceramic vulcanized engagugiyosisixhobo esidibeneyo esisebenzayo esenziwe ngokubopha i-alumina ceramic ecocekileyo kakhulu (umxholo we-Al₂O₃ ≥92%) kunye ne-raber matrix ngenkqubo ye-vulcanization eshushu. Idibanisa ubunzima obukhulu be-ceramic kunye nomthamo we-elastic buffering werabha, okwenza ukuba ifaneleke ukukhuselwa komphezulu wezixhobo zoshishino phantsi kweemeko ezichaphazela kakhulu kunye nezo zigugileyo. Ubunzima obuqhelekileyo be-alumina ceramic layer bufikelela kwi-HRA 85-90, uxinano luqala kwi-3.6 ukuya kwi-3.9 g/cm³, kwaye ukumelana kwayo nokugugile kumalunga ne-10 ukuya kwi-15 ngaphezu kweepleyiti zesinyithi eziqhelekileyo.

Iinkcukacha eziphambili zokusebenza ziquka: ubukhulu bethayile zeseramikhi buqhele ukuba yi-15-30 mm, ubukhulu bereyibha buyi-4-15 mm, kunye namandla exolo apheleleyo ≥12 kN/m. Ubushushu bokusebenza buqala kwi--40°C ukuya kwi-+120°C, kunye nokunyamezela okwethutyana ukuya kuthi ga kwi-150°C. I-coefficient of friction ingaphantsi kwe-0.2, nto leyo enciphisa ngempumelelo ukunamathela kwezinto kunye nemingcipheko yokuvaleka ngexesha lokuhambisa. Ngenkqubo ye-vulcanization, ukudibana kweekhemikhali kwi-ceramic-raber interface kuthintela ukuqhekeka okanye ukwahlukana, kwandisa ubomi benkonzo ngeminyaka emi-3-5 xa kuthelekiswa nee-liners zentsimbi ze-manganese eziqhelekileyo.

Izicelo eziphambili ziquka: iindawo zokudlulisela iibhanti zokuhambisa, iichutes, kunye neehoppers kwimizi-mveliso yezemigodi kunye neyonke; iichutes zokutya kunye neendawo zokwahlulahlula kwizityalo zentsimbi nezesamente; kunye neetyhubhu zokuwisa amalahle kwiinkqubo zokuphatha amalahle kwizityalo zamandla. Ngexesha lokufakwa, ipleyiti evulcanized inamathele kwipleyiti yesiseko sezixhobo nge-cold bonding okanye i-hot vulcanization, ngaphandle kwezibophelelo ezintsonkothileyo zoomatshini. Kwiindawo ezigugileyo, ifomyula ye-zirconia-toughened composite (Al₂O₃-ZrO₂) ingakhethwa, yonyusa ukuqina kokuqhekeka ukuya kwi-4.5-5.5 MPa·m¹/², ixhathisa ngakumbi umonakalo wempembelelo ovela kwizinto ezinkulu.
