Inqubo ye-Ceramic sintering

I-Sintering ubuchwepheshe obusebenzisa amandla okushisa ukuhlanganisa amabhilidi ayimpuphu. Incazelo ye-sintering ibhekisela kunqubo yokuqina kwe-porous ceramic billet ngaphansi kwezimo zokushisa eziphezulu, indawo engaphezulu iyancishiswa, i-porosity iyancishiswa, futhi izakhiwo zemishini ziyathuthukiswa. Kuphela ngokuqonda umthetho wokushintsha umzimba ohlelweni lokushisa okuphezulu kokushisa, ukukhetha kahle nokuklama iziko, ukwakheka ngokwesayensi nokusebenzisa uhlelo lokudubula, nokusebenzisa ngokuqinile izinqubo zokusebenza zokulayisha nokudubula, ikhwalithi yomkhiqizo ingathuthukiswa, ukusetshenziswa kukaphethiloli kuncishiswe, futhi kutholakale izinzuzo ezinhle zezomnotho.

Ipharamitha ye-Sintering

Imingcele yezobuchwepheshe ethinta ukucwiliswa kwezinto zobumba

(1) Umthelela wezinga lokushisa lokudubula ekusebenzeni komkhiqizo

1. Izinga lokushisa lokudubula libhekisela ekushiseni okuhambisanayo lapho umzimba we-ceramic uxoshwa ukuze uthole indawo efanelekile, okungukuthi, izinga lokushisa lokumisa umlilo ngesikhathi sokusebenza.
2. Izinga lokushisa lokudubula lithinta ngokuqondile ubukhulu kanye nenani lezinhlamvu. Ngokusatshalaliswa kwesigaba esiqinile noma ukuvuselelwa kwesigaba se-liquid, kuyazuzisa ukwandisa izinga lokushisa lokudubula. Kodwa-ke, ku-porcelain ekhethekile, izinga lokushisa eliphezulu kakhulu lizokwenza ukuthi usayizi wokusanhlamvu ube mkhulu kakhulu noma inani elincane lezinhlamvu likhuphuke kakhulu, licekele phansi ukufana kwesakhiwo senhlangano, ngaleyo ndlela kulimaze izakhiwo ze-electromechanical zomkhiqizo.

(2) Umthelela wokubamba isikhathi ekusebenzeni komkhiqizo

Ukugcina izinga lokushisa eliphakeme kakhulu lokudubula isikhathi esithile, ngakolunye uhlangothi, kuzokwenza izinguquko ezingokomzimba nezamakhemikhali ziphelele, ukuze umzimba oluhlaza ube nesigaba esanele soketshezi kanye nosayizi ofanele wokusanhlamvu, futhi ngakolunye uhlangothi, ukwakheka kwenhlangano nakho kuzofana kakhulu. Kodwa-ke, uma isikhathi sokugcina ukushisa siside kakhulu, izinhlamvu zekristalu zizoncibilika, okungahambisani nokwakhiwa kwe-skeleton eqinile endaweni engenalutho futhi kunciphisa izakhiwo zemishini.

(3) Umthelela womkhathi wokudubula ekusebenzeni komkhiqizo

1. Umthelela womkhathi ekwandeni kokudubula ngokweqile kwemizimba yobumba
2. Umthelela womkhathi ekuncipheni nasekuncipheni komzimba oluhlaza
3. Umthelela womkhathi embaleni nasekudluliseni kokungenalutho kanye nekhwalithi yongqimba olucwebezelayo.

(4) Umthelela wokushisisa nokupholisa isivinini ekusebenzeni komkhiqizo

I-Solid-phase sintering ngokuvamile ingahlukaniswa ngezigaba ezintathu: isigaba sokuqala, esibonakaliswa ngokuyinhloko ngokushintsha kwesimo sezinhlayiyana; isigaba esiphakathi, esibonakaliswa ngokuyinhloko ngokushintsha kwesimo se-pore; isigaba sokugcina, esibonakaliswa ngokuyinhloko ngokunciphisa usayizi we-pore.

I-Liquid phase sintering (i-LPS ngamafuphi) isho ukucwiliswa komzimba oqukethe izimpushana eziningi. Izinga lokushisa le-sintering liphakeme okungenani kunezinga lokushisa elincibilikayo lenye yezimpushana, ukuze uketshezi lwe-sintering lwesigaba senzeke ngesikhathi senqubo yokucwilisa. inqubo.

inzuzo:

1. Thuthukisa amandla okushayela e-sintering.
2. Izinto ezihlanganisiwe ze-Ceramic ezine-microstructure elawulwayo kanye nezakhiwo ezenziwe kahle zingalungiswa

I-Ceramics Of Ignition Pin

I-sintering-hot press sintering efakiwe

Ukucindezela okushisayo kusebenzisa ukucindezela kokungenalutho ngesikhathi esifanayo phakathi nenqubo ye-sintering, okusheshisa inqubo yokuminyana. Ngakho-ke, izinga lokushisa le-hot press sintering liphansi futhi isikhathi se-sintering sifushane.

Ubuchwepheshe bokucindezela okushisayo bunomlando weminyaka engu-70 futhi baqala ukusetshenziswa ekulungiseni i-tungsten carbide nezingxenye eziminyene ze-tungsten powder. Manje isetshenziswa kabanzi emboniniukukhiqizwa kwe-ceramics,i-powder metallurgykanye nezinto eziyinhlanganisela.

Izinzuzo ze-hot press sintering

1. Ingcindezi yokubumba edingekayo ingu-1/10 kuphela wendlela yokucindezela okubandayo
2. Ukwehlisa izinga lokushisa le-sintering kanye nokunciphisa isikhathi se-sintering kuvimbela ukukhula kwezinhlamvu.
3. Kulula ukuthola imikhiqizo enezakhiwo ezinhle zemishini kanye nezakhiwo zikagesi.
4. Iyakwazi ukukhiqiza imikhiqizo enezimo eziyinkimbinkimbi kanye nobukhulu obunembile.
