Ceramic e fetohile thepa ea khetho bakeng sa ho apara ka bohlale ka lebaka la bopaki ba eona ba pele, letlalo le bonolo, le sa tsitsang, 'mala oa jade le theko e tlaase. 'Me ho bopa ente ea ceramic ke e' ngoe ea mekhoa ea mantlha ea ho bopa ea likarolo tse bohlale tse ka roaloang tsa ceramic.
Mokhoa oa ho bōpa ente ea ceramic
Moetso oa ente ea ceramicke mokhoa o haufi oa ho bopa oa polasetiki oa boholo ba net o ntlafalitsoeng motheong oa theknoloji ea ho bopa ente ea polymer. Mokhoa oa mantlha oa ho bopa ka mokhoa o bohlale oa ho roala ente ea ceramic haholo-holo o kenyelletsa mekhahlelo e mene: ho fepa, ho bopa ka ente, ho tlosa mafura le ho sintering.
1. Ho lokisetsa lijo The yttrium stabilized zirconia powder le surfactant li lekanngoa ka tekanyo, ethanol e kenngoa, ebe e kopantsoe ke ho sila ka bolo, e omisitsoeng le ho hlahlojoa ho fumana slurry, ebe e kopantsoe le binder, e kopantsoeng le granulated ho fumana lijo tsa ente.
Senotlolo sa ho lokisa lijo:
Khetha e loketseng binder, binder le ceramic phofo tshebeletsano le ho kuta e hasana hantle, felisa agglomeration;
Likahare tse loketseng tsa binder, e le hore fepa e be le metsi a matle;
Keketseho ea phofo ea ceramic (litaba tse tiileng) le ho fokotseha hoa deformation.
2, ho bopeha ka ente e tla ba lijo tsa ho bopa ka ente tse kentsoeng mochining oa ho bopa ente, e cheselitsoeng ka har'a mokelikeli oa viscous, ka mocheso o itseng le khatello e phahameng ea ente ka har'a hlobo ea tšepe, e pholileng kamora ho hlobola ho fumana 'mele oa ceramic billet. Senotlolo sa ho etsa ente:
Moralo o nepahetseng oa hlobo le ts'ebetso (heke, semathi, ho nepahala, thepa, jj.)
Ho beha le ho ntlafatsa liparamente tsa ente (mocheso, khatello, mocheso oa hlobo)
Ho felloa ke matla le khatello ea 'mele nakong ea ho tlatsa hlobo
3, degreasing degreasing ke ts'ebetso ea ho tlosa karolo ea binder ho ente ea ceramic billet ka mekhoa ea 'mele kapa ea lik'hemik'hale. Ka lebaka la sistimi e fapaneng ea li-binder, mokhoa oa ho theola o fapane, mekhoa ea ho theola ente ea ceramic e kenyelletsa: ho theola mocheso, ho qhibiliha ha solvent, catalytic degreasing, khetha thekenoloji e sebetsang hantle le e bolokehileng bakeng sa ho theola, fumana lefeela.
4. Sintering
Sekhahla sa ceramic se ile sa chesoa ka mocheso o phahameng oa 1300 ° C ~ 1800 ° C. Sintering ke mokhoa oa ho etsa billet ea ceramic. Karolo e kholo ea ts'ebetso ea lihlahisoa tsa ceramic e khethoa ke sintering. Zirconia ceramics hloka phahameng segokanyipalo le junifomo sintering, eseng feela degreasing tshebetso ke ea bohlokoa haholo, empa hape angoa ke phofo, additives, sintering mocheso le nako, khatello le sintering sepakapaka le lintlha tse ling.
Melemo ea ho bopa ente ea ceramic
Likarolo tse bohlale tse ka roaloang tsa ceramic li kenyelletsa mokotla oa oache oa ceramic, bezel ea ceramic, daela ea ceramic, sekoaelo se ka tlase sa ceramic, moqhaka oa ceramic, ketane ea oache ea ceramic le lihlahisoa tse ling, boholo bo bonyenyane, litlhoko tse phahameng tse nepahetseng.
Melemo ea ho sebelisa mochini oa ente ea ceramic bakeng sa ho apara ka bohlalelikarolo tsa ponahalo ea ceramicke:
E ka ba haufi le nete ea ho bopa geometry e rarahaneng 'me e na le litlhoko tse khethehileng tsa likaroloana tse nyenyane tsa ceramic, lihlahisoa tse entsoeng ka ho nepahala tse phahameng, junifomo ea botala bo botala, matla a phahameng, ts'ebetso ea' mele e sintered le boleng ba sehlahisoa sa boleng bo botle, e le hore lihlahisoa tsa sintered ceramic ntle le machining kapa ts'ebetso e fokolang, e le ho fokotsa litšenyehelo tse theko e boima tsa ho sebetsa ka ceramic;
Mokhoa oa ho bōptjoa o na le tekanyo e phahameng ea ho sebelisa mechine le ho iketsetsa, potoloho ea ho bopa e khutšoanyane, tsamaiso le taolo ea ts'ebetso ea tlhahiso e boetse e le bonolo haholo, e bonolo ho finyella tlhahiso ea bongata, tlhahiso e kholo;
Lihlahisoa tsa ceramic tse bōpiloeng li na le ho nepahala ho phahameng ka ho fetisisa le ho qeta holimo holimo, holimo ho ka fihla ho 5um. Ka hona,Theknoloji ea ho theha ente ea ceramic ea CIMe fetohile e 'ngoe ea mekhoa ea ho theha theknoloji e teng ea ho etsa ceramic.
