Zirconia Block yog dab tsi?

Raws li peb txhua tus paub muaj peb hom ntaub ntawv siv los kho hniav: zirconia thaiv cov khoom thiab cov khoom siv hlau. Zirconium oxide tshwm sim raws li monoclinic, tetragonal thiab cubic crystal form. Cov ntu sintered tuab tuaj yeem tsim ua cov cubic thiab/lossis daim ntawv tetragonal siv lead ua. Txhawm rau kom ruaj khov cov txheej txheem siv lead ua no, cov khoom siv ruaj khov xws li magnesium oxide (MgO) lossis yttrium oxide (Y2O3) yuav tsum tau ntxiv rau ZrO2.

Vim li cas zirconia thaiv yog cov khoom tsim nyog tshaj plaws hauv kev kho hniav kho?

Cia peb tham daim ntawv zirconia tsim. Cov hniav zirconia thaiv yog ua los ntawm crystalline oxide daim ntawv ntawm zirconium, thiab nws muaj cov hlau atom hauv cov siv lead ua tab sis yeej tsis suav tias yog hlau. Vim tias nws cov khoom ruaj khov thiab muaj peev xwm sib xws tau, cov kws phais neeg lossis kws kho mob siv cov hniav zirconia thaiv hauv ntau qhov chaw kho hniav. Txawm tias nws tau siv hauv kev cog ntoo vim nws suav tias yog cov khoom siv muaj zog tshaj plaws.

Txawm hais tias muaj ntau yam khoom siv hauv kev lag luam kho hniav, cov hniav zirconia thaiv kuj tseem hu ua ceramic block yog nto moo tshaj plaws ntawm cov kws kho hniav thiab cov neeg mob.

Qee qhov zoo rau kev kho hniav zirconia thaiv:

-Raws li nws tau tsim los siv kev tsim txuj ci siab. Nrog lub siab tawg tawv, ua kom sov zoo ib yam li cov hlau nrum, tsis tshua muaj siab dabtsi yog khoov lub zog thiab lub zog tensile, tiv taus hnav thiab tiv taus xeb, tsis muaj thermal conductivity

- Tsis tas li, nws tau pom zoo los ntawm cov koom haum hauv tebchaws. Tsis tas li, cov thaiv no tau dhau qee qhov kev sim siab, kom paub tseeb tias nws muaj kev nyab xeeb kiag li.

– Hniav zirconia thaiv yog cov khoom lag luam zoo, thiab tseem nws ua rau cov hniav ruaj khov thiab zoo nkauj dua.

Nce Thaum cov khoom raug cog rau sab hauv tus neeg mob, nws yuav muab lub neej txee zoo rau cov khoom.

– Lwm qhov txiaj ntsig tseem ceeb ntawm qhov zirconia thaiv hniav no yog nws yuav txo lub sijhawm ua ntej ziab thiab txhim kho qhov pom kev thaum lub sijhawm zas xim.

Features Cov yam ntxwv tseem ceeb tshaj plaws ntawm cov khoom no yog nws tuaj yeem muaj cov xim zoo nkauj rov tshwm sim, thiab tseem nws tuaj yeem phim txhua qhov loj me thiab cov duab.
