Akuwona wonke ama-zirconia powders atholakala ngokuthengisa afanayo.Umehluko phakathi kwemikhiqizo ngosayizi wokusanhlamvu kanye nezithasiselo kulawula kakhulu amandla we-zirconia block material, ukuzinza kwesikhathi eside, kanye nokuguquguquka.
1. Ngaphezu kwalokho, izinqubo ezihlukahlukene lapho izimpushana zamazinyo ze-zirconia zakhiwa khona zibe amabhulokhi e-zirconia yokugaya zithonya kakhulu izinga lomkhiqizo wokugcina.Ukucindezela kwe-axial okuyi-unidirectional kudala ukwakheka kwebhulokhi ye-zirconia yokugaya enembe kakhulu kodwa engenakho ukuhambisana kwezinto ezibonakalayo ngakho-ke ayilungele ukubuyisela okukhulu.
2. Ngakolunye uhlangothi, ukucindezela okubandayo kwe-isostatic (CIP) kusebenzisa i-liquid medium, njengamanzi, ukufaka ingcindezi ngokulinganayo kuzo zonke izinhlangothi ku-zirconia powder evalwe esikhunjini ukuze kugcinwe isimo sayo.
3. Izingcindezi eziphakeme kakhulu ezihilelekile nge-CIP zinciphisa futhi zisuse ama-voids ku-powder ukuze kwandiswe ukuminyana kwezinto futhi kukhiqize i-zirconia ye-green-state (engafakwanga) ene-homogeneity enhle kakhulu kuyo yonke into.I-green-state zirconia block bese i-sintered ngaphambili ukuze ivumele ukuthi igaywe kalula futhi igaywe ngemuva kochwepheshe.Isinyathelo sokugcina sokukhiqiza sibandakanya ukucwilisa i-zirconia emazingeni okushisa aphezulu kakhulu (1350 ° C kuya ku-1500 ° C) lapho ukubuyisela kokugcina kuba lukhuni futhi kunciphe ngokulandelana ngo-20% kuya ku-25% ukuze kuzuzwe amandla adingekayo kanye nezindawo zokubona.
Izizukulwane zokuqala zezinto zokugaya ze-CIP zirconia eziphezulu zamandla ziphumele ekubuyiselweni kwe-monochromatic nokuminyene opaque okubonisa ubuhle obulinganiselwe ngaphandle kokuthi kufakwe izendlalelo.Kodwa-ke, phakathi neminyaka engu-5 edlule, ukuphindaphindwa okusha kwezinto zebhulokhi ye-zirconia kuguqukele ekubeni amabhulokhi e-zirconia yokugaya athambekele ekukhanyeni okuphezulu kakhulu kanye nebhulokhi ye-zirconia enomthunzi ngaphambili noma amabhulokhi e-zirconia anezingqimba eziningi akhulisa kakhulu umphumela wobuhle ngenkathi ehlisa izinqubo zokukhiqiza.Inzuzo enkulu yalezi zinto eziguquguqukayo eziphezulu ukuthi zidinga ukuncishiswa okuncane kunokubuyiselwa kwe-monolithic glass-ceramic futhi zinomusa kumazinyo emvelo aphikisayo.
Onyakeni odlule, ukwakheka okusha kwamabhulokhi okugaya i-zirconia kufaka phakathi lawo angashiswa ngamahora angu-2.Njengomkhiqizi we-zirconia block amathathu aphezulu e-china, ibhulokhi ye-zirconia yase-Yucera ifinyelela ngokugcwele le mfuneko ngenqubo yokukhiqiza engenhla, engafakwa ngokushesha emahoreni angu-2 ngecala elithile eliphuthumayo, ngaphansi kwamayunithi angu-3 umqhele we-zirconia.Ibhulokhi ye-zirconia efakwe ngaphambili kanye nebhulokhi ye-zirconia enezingqimba eziningi konga kahle isikhathi sikachwepheshe wamazinyo emibaleni efayo, elungele ukubuyisela isikhathi eside.
Ungathenga kuphi ibhulokhi ye-zirconia yamazinyo?Impela Yucera, wamukelekile xhumana nathi.
