I-Ceramic Injection Molding Cold Sintering (CS)

Inqubo eyisisekelo yeukubumba umjovo we-ceramicUbuchwepheshe be-CS wukwengeza inani elincane lesixazululo esinamanzi ku-powder ceramic ukumanzisa izinhlayiya, futhi indawo engaphezulu yempushana iyabola futhi incibilike ingxenye esixazululweni, ngaleyo ndlela ikhiqize isigaba se-liquid phakathi kwe-particle-particle interface. Faka i-powder emanzi esikhunjini, ukushisa isikhunta, futhi usebenzise ukucindezela okukhulu ngesikhathi esifanayo. Ngemuva kokugcina ukucindezela nokuyigcina isikhathi esithile, i-ceramic material eminyene ingalungiswa. Phakathi nale nqubo, i-microstructure ye-izinto ze-ceramiciyaguquguquka. njengoba isithombe sibonisa.

Nakuba kunezici eziningi ezithonya ezihlelekile zenqubo ye-CS, izinto zokusebenza ezisetshenziswa yilobu buchwepheshe zilula uma kuqhathaniswa. , Imishini ye-ceramic CS ngokuyinhloko ihlanganisa umshini wokunyathelisa ovamile, amapuleti amabili okushisa afakwe phezulu nangaphansi komshini wokunyathelisa, kanye nejakhethi yokushisisa elawulwa nge-elekthronikhi nayo ingasongwa esikhunjeni sokushisisa impushana.

I-Oscillating Pressure Sintering ye-Ceramic Injection MoldingCIM (OPS)

Ubuchwepheshe obuhlukahlukene obukhona bokufaka ingcindezi busebenzisa ingcindezi engaguquki. Ukwethulwa kwengcindezi ye-static ngesikhathi sokukhulelwainqubo sinteringkusiza ukuqeda ama-pores futhi kuthuthukise ukuminyana kwezitsha zobumba, kodwa kunzima ukuhlanganisa ngokuphelele i-ionize futhi ibophe ngokuhlanganyela izitsha zobumba ezikhethekile. Ukukhishwa kwama-pores ngaphakathi kwempahla kusenemikhawulo ethile yokulungiswa okufunayo kwamandla aphezulu, ukuqina okuphezulu, ubulukhuni obuphezulu kanye nezinto ezinokwethenjelwa okuphezulu.
Izizathu eziyinhloko zemikhawulo ye-HP static pressure sintering ibonakala kulezi zici ezi-3 ezilandelayo:

• ① Ngaphambi kokuqala kokucwilisa kanye nasesigabeni sokuqala sokucwilisa, ingcindezi engaguquki ayikwazi ukuqaphela ngokugcwele ukuhlelwa kabusha kwezinhlayiyana zempushana ekubunjweni ukuze kutholakale ukuminyana okuphezulu kokupakisha;
• ② Ezigabeni ezimaphakathi nezakamuva ze-sintering, ukugeleza kwepulasitiki nokuqedwa kwama-agglomerate kusenomkhawulo, futhi kunzima ukufeza ukuminyana okuphelele kwezinto ezibonakalayo;
• ③ Esigabeni sakamuva se-sintering, kunzima ukuqeda ngokuphelele ama-pores asele ngokucindezela okuqhubekayo.

Kuze kube manje, iqembu locwaningo lombhali lihlongoze umbono omusha wokuklama wokwethula ingcindezi ye-oscillating eguquguqukayo ukuze ithathele indawo ingcindezi ekhona engaguquki enqubweni ye-powder sintering, futhi yahola ekuthuthukiseni ubuchwepheshe nemishini ye-OPS emhlabeni. Ngaphansi kwesenzo sokucindezela okukhulu okungaguquki, ingcindezi ye-oscillating enemvamisa eguquguqukayo kanye ne-amplitude ibekwe phezulu ukuze kuguqulwe "amandla afile" asetshenziswa ekungeneni kwendabuko abe "amandla". Umdwebo wohlelo lwedivayisi yokuhlanganisa ingcindezi ye-oscillating kanye nesimiso kuboniswa esithombeni.

Ubuchwepheshe obusha be-OPS bunezinzuzo ezihlukile zokulungiswa kwezinto ezinokuminyana kwethiyori eduze (okungaphezu kuka-99.9% wokuminyana kwethiyori), ukukhubazeka okuphansi, kanye ne-ultra-fine grain microstructure. nokuthembeka kunikeza indlela entsha.
