Ukuvimbela Ukuphuka Kwe-Zirconia: Izimbangela Nezixazululo Zokubuyiselwa Kwe-Zirconia

Ukulungiswa kwe-Zirconia kuvame ukuqhekeka, ukuqhekeka okuncane, kanye nokuqhekeka kulo lonke uhambo—kusukela ekwakhiweni kuya ekusikeni, ukuhlukaniswa kwamazinyo, ukusha, ukugaya, kanye nokusetshenziswa kwe-ceramic. Izinkinga eziyinhloko zigxile ezicini ezinhlanu ezibalulekile: ukwakheka kwesakhiwo, ukusebenza kwemishini, imingcele yenqubo, ukuhambisana kwezinto, kanye nokulungiselela emtholampilo . Lo mhlahlandlela uhlanganisa izimbangela nezixazululo zesigaba ngasinye somsebenzi.

Izinkinga Ezithile:

• Ubukhulu obunganele, ingxenye encane yesixhumi, ubude obukhulu bebhuloho
• Indawo engafanele yembobo yesikulufu, ukunqunywa ngokweqile
