Ukukhetha okuhle kakhulu kwemidiya yokugaya esebenza kahle kakhulu - ubuhlalu be-zirconia kanye nezicelo zabo
Emkhakheni wokugaya nokuhlakazeka okumanzi okunembe kakhulu, izidingo zokusebenza kwemidiya yokugaya ziyanda. Ikakhulukazi ezimbonini ezifana namandla amasha, i-elekthronikhi, izinto zobumba ezinembile kanye nezingubo eziphezulu, imithombo yokugaya yendabuko ayisakwazi ukuhlangabezana nezidingo eziphelele zokugaya okuhle kakhulu, ukulawula ubumsulwa kanye nokwenza ngcono ukusetshenziswa kwamandla. Ngalesi sikhathi, ubuhlalu be-zirconia, njengohlobo olusha lwemidiya yokugaya ye-ceramic esebenza kahle kakhulu, kancane kancane iba yinto ebalulekile emakethe.
Ziyini izinhlayiya ze-zirconia?
Ama-Zirconia bead ayizindilinga ezincane eziqoshwe ngezinto ze-zirconia ezizinzile kakhulu ezinamandla aphezulu, ubulukhuni obuphezulu, ubuningi obukhulu kanye nokumelana okuhle kakhulu nokuguguleka. Izinto zayo eziyinhloko zokusetshenziswa, i-zirconia, inokuqina okuhle kanye nokungangeni kwamakhemikhali, okwenza ama-zirconia beads agcine ukuzinza okuhle kakhulu kanye nokuphila kwesikhathi eside kwenkonzo ezinhlelweni zamandla aphezulu, ukusika okuphezulu kanye ne-viscosity ephezulu.
Izinhlobo ezivamile ze-zirconia ubuhlalu zifaka:
Ubuhlalu be-zirconia obuzinzile be-Y-TZP: bufakwe i-yttrium oxide, enobukhulu obukhulu kanye nobunzima, obufanelekela ukugaya ezingeni eliphansi;
Ubuhlalu be-zirconia obuhlanganisiwe be-ZTA: benziwe nge-alumina kanye ne-zirconia ehlanganisiwe, engabizi kakhulu;
Ubuhlalu be-zirconia obuzinzile kancane be-PSZ: ukuqina okuhle kakhulu, okufanelekela ukugaya okunamandla amakhulu noma izinqubo zokugaya eziyinhloko.
Izinzuzo zokusebenza kwama-bead e-zirconia
Isizathu sokuthi kungani ubuhlalu be-zirconia bungabonakala phakathi kwemithombo eminingi yokugaya kungenxa yezici zabo ezibalulekile ezilandelayo:
Ubuningi obukhulu (5.8 ~ 6.2 g/cm³): buletha amandla aphezulu okugaya futhi buthuthukisa ukusebenza kahle kokugaya;
Ubulukhuni obuphezulu (ubulukhuni be-Mohs ≥8): akulula ukubugqoka, ngeke kubangele ukungcola kokusila;
Ukuqina okuphezulu: akulula ukuphula ngisho noma kuthinteka ngamandla aphezulu, okuqinisekisa ukuqina kokugaya;
Izinga lokuguga eliphansi: ukulahleka okuncane kakhulu kwama-beads ngesikhathi seyunithi ngayinye, okwandisa impilo yesevisi;
Ubuso obubushelelezi kanye nobubanzi obuphezulu: ukusebenza okubushelelezi, kunciphisa ukuguguleka kwemishini kanye nokusetshenziswa kwamandla.
Uhla olubanzi lwezicelo
Ubuhlalu be-Zirconium oxide bungasetshenziswa kabanzi emishinini ehlukahlukene yokugaya emanzi (njengemishini yokugaya evundlile yesihlabathi, imishini yokugaya evundisiwe, imishini yokugaya ibhasikidi, njll.), futhi ukusetshenziswa kwayo okukhethekile kufaka phakathi kodwa akukhawulelwe ku:
Izinto ezintsha zamandla: ukugaya i-lithium iron phosphate, izinto ze-ternary, ama-electrode angemuhle e-silicon-carbon, njll.;
Izitsha zobumba ezisebenza kahle kakhulu: ezisetshenziselwa ukuhluza i-aluminium oxide ngempuphu, i-silicon nitride, i-silicon carbide, njll.;
Izinto zamakhemikhali ze-elekthronikhi: njenge-ITO conductive glass slurry, i-MLCC ceramic powder, njll.;
Uyinki wokumboza ophezulu: ukusabalala okufanayo kwamayinki e-UV, ukumboza okuncane, kanye noyinki kagesi;
Imithi nokudla: okusetshenziselwa ukugaya i-micronization engenakungcola emikhiqizweni yezokwelapha kanye nokudla okusebenzayo.
Isifinyezo
Njengendlela yokugaya ethuthukisiwe ehlanganisa amandla aphezulu, ubumsulwa obuphezulu kanye nokuqina okuphezulu, ubuhlalu be-zirconia buba yinto ebalulekile ezimbonini ezahlukahlukene ukuthuthukisa ukunemba kwempuphu, ukuzinzisa izinqubo zokukhiqiza, kanye nokwenza ngcono izakhiwo zezindleko. Ngokuthuthuka okuqhubekayo kokukhiqiza ngokunemba kanye nokukhiqizwa okuluhlaza, ubuhlalu be-zirconia buzodlala indima ebaluleke kakhulu ekusetshenzisweni kokugaya okumanzi esikhathini esizayo.
