Ukhetho olufanelekileyo kwimidiya ephezulu yokugaya - ubuhlalu be-zirconia kunye nezicelo zabo
Kwintsimi yokugaya okumanzi kunye nokusabalalisa okuphezulu, iimfuno zokusebenza kwimidiya yokugaya ziyanda. Ngokukodwa kumashishini anjengamandla amatsha, i-electronics, i-ceramics echanekileyo kunye neengubo eziphakamileyo eziphezulu, imidiya yendabuko yokusila ayinakukwazi ukuhlangabezana neemfuno ezibanzi zokugaya i-ultra-fine, ukulawulwa kobunyulu kunye nokulungiswa kokusetyenziswa kwamandla. Ngeli xesha, ubuhlalu be-zirconia, njengohlobo olutsha lwemithombo yeendaba yokugaya i-ceramic ephezulu, ngokuthe ngcembe iba yingqwalasela yentengiso.
Yintoni amaso zirconia?
Amaso eZirconia ngamacandelo amancinci afakwe kwizixhobo ezizinzile ze-zirconia ezinamandla aphezulu, ukuqina okuphezulu, ukuxinana okuphezulu kunye nokumelana nokunxiba okugqwesileyo. Izinto zayo ezisisiseko eziluhlaza, i-zirconia, inobunzima obuhle kunye nokungabikho kweekhemikhali, okwenza ukuba ubuhlalu be-zirconia bugcine ukuzinza okugqwesileyo kunye nobomi benkonzo ekuxinaniseni kwamandla aphezulu, ukucheba okuphezulu kunye neenkqubo eziphezulu ze-viscosity.
Iintlobo eziqhelekileyo zamaso e-zirconia ziquka:
I-Y-TZP igxininise ubuhlalu be-zirconia: i-doped nge-yttrium oxide, enobuninzi obuphezulu kunye nobunzima, ifanelekile kwi-nano-level grinding;
Amaso e-zirconia ahlanganisiweyo e-ZTA: ayenziwe nge-alumina kunye ne-zirconia ehlanganisiweyo, enexabiso eliphantsi;
I-PSZ izinzile ngokuyinxenye amaso e-zirconia: ukuqina okugqwesileyo, okufanelekileyo kumandla aphezulu okugaya okanye iinkqubo zokugaya eziphambili.
Iinzuzo zokusebenza kweentsimbi ze-zirconia
Isizathu sokuba amaso e-zirconia abonakale phakathi kwemithombo yeendaba ezininzi zokusila ikakhulu ngenxa yeempawu zabo ezibalulekileyo ezilandelayo:
Uxinaniso oluphezulu (5.8~6.2 g/cm³): izisa amandla ekhinetic aphezulu okusila kunye nokuphucula ukusebenza kakuhle kokusila;
Ubunzima obuphezulu (ubunzima be-Mohs ≥8): akulula ukugqoka, akuyi kubangela ukungcoliswa kokungcola kwizinto zokugaya;
Ukuqina okuphezulu: akulula ukuphula phantsi naphantsi kwempembelelo ephezulu, ukuqinisekisa ukuzinza kokugaya;
Ixabiso eliphantsi lokunxiba: ilahleko encinci kakhulu yamaso ngexesha leyunithi, ukwandisa ubomi benkonzo;
Umphezulu ogudileyo kunye ne-sphericity ephezulu: ukusebenza kakuhle, ukunciphisa ukunxiba kwezixhobo kunye nokusetyenziswa kwamandla.
Uluhlu olubanzi lwezicelo
Amaso e-Zirconium oxide anokusetyenziswa ngokubanzi kwizixhobo zokusila ezimanzi ezahlukeneyo (ezifana nezingqusho zesanti ezithe tyaba, ii-mill ezinyakaziswayo, ii-basket grinders, njl.njl.), kwaye izicelo zazo ezithile ziquka kodwa aziphelelanga apha:
Izinto zamandla amatsha: ukugaya i-lithium iron phosphate, izinto ze-ternary, i-silicon-carbon negative electrode, njl.;
Iikeramics ezisebenza kakhulu: ezisetyenziselwa ukucokisa umgubo we-aluminium oxide, i-silicon nitride, i-silicon carbide, njl.;
Izinto zeekhemikhali ze-elektroniki: ezifana ne-ITO conductive glass slurry, i-MLCC powder ceramic, njl.;
Iinki zokugquma ezikumgangatho ophezulu: ukusasazwa okulinganayo kwee-inks ze-UV, ii-nano coatings, kunye nee-inks ze-elektroniki;
Iyeza kunye nokutya: kusetyenziselwa ukucola i-micronization engangcolisekiyo kwi-biopharmaceuticals kunye nokutya okusebenzayo.
Isishwankathelo
Njengomgangatho ophezulu wokugaya odibanisa amandla aphezulu, ukucoceka okuphezulu kunye nokuzinza okuphezulu, ubuhlalu be-zirconia buba yinto ebalulekileyo kumashishini ahlukeneyo ukuphucula ukuchaneka kwepowder, ukuzinzisa iinkqubo zokuvelisa, kunye nokwandisa izakhiwo zeendleko. Ngenkqubela phambili eqhubekayo yokwenziwa ngokuchanekileyo kunye nemveliso eluhlaza, amaso e-zirconia aya kudlala indima engundoqo kwizicelo zokusila ezimanzi kwixesha elizayo.
