Ob lo lus nug ntawd nyob rau hauv qhov kub thiab txias sib txawv kiag li thiab xav tau cov khoom siv sib txawv kiag li. Yog vim li cas koj yuav tsis pom cov khoom siv hauv chaw kuaj hniav suav tias cov no yog cov khoom siv sib pauv tau.

Lub cub tawg Zirconia Sintering yog dab tsi thiab nws ua haujlwm li cas?

Lub cub tawg zirconia muaj ib txoj haujlwm: sib xyaw cov khoom zirconia ua ke hauv qab cua sov siab kom cov qhov me me sab hauv ploj mus thiab cov khoom siv ntsws los ntawm lub xeev porous mus rau qhov ze-tag nrho. Cov txheej txheem ntawd - densification - yog tib txoj kev zirconia tau txais nws lub zog kawg, translucency, thiab qhov tseeb. Dhia nws, thiab qhov koj tau milled tseem yog ib qho mos mos ceramic dawb uas tsis muaj kev lag luam mus rau hauv tus neeg mob lub qhov ncauj.

Nov yog li cas cov txheej txheem ua haujlwm tiag tiag: tus kws kho tshuab mills cov duab kho dua tshiab tawm ntawm lub zirconia block uas tau sintered ("ntsuab" lossis "dawb"), uas mos thiab yooj yim txiav ntawm theem no. Tus qauv tsim tau txhob txwm loj dua 20-25% kom suav nrog kev shrinkage thaum lub sijhawm firing. Daim milled ces mus rau hauv lub cub tawg sintering, qhov chaw nws ua raws li cov chaw tsim khoom pom zoo kom cua sov, tuav, thiab txias, shrinking mus rau nws qhov kawg tsim qhov ntev thaum densifying tib lub sijhawm. Txhua kauj ruam hauv cov saw hlau ntawd yog txuas - txawm tias qhov sib txawv me me hauv cov kab sintering tshwm sim tom qab ua qhov teeb meem haum hauv tus neeg mob lub qhov ncauj.

Qhov teeb meem feem ntau tsis yog qhov kub siab tshaj plaws tsis txaus - nws yog qhov kub tsis sib xws hauv lub chamber, uas qhia tau tias yog qhov ntxoov ntxoo tsis sib xws hauv tib lub pawg, lossis kev ntxhov siab sab hauv thiab kev sib txhuam hauv cov choj loj dua uas cua sov tsis sib xws. Qhov no yog qhov teeb meem uas Dentex Q7 tau tsim los daws, siv nws cov thev naus laus zis ARCS (Automatic Rapid Compensation Sintering): lub kaw lus tsa tsis muaj kev co uas kho qhov deb ntawm cov khoom ua haujlwm thiab phab ntsa chamber, muab rau koj kev tswj hwm nruj dua ntawm kev cua sov, tuav, thiab txias kom koj tuaj yeem txiav lub sijhawm voj voog yam tsis muaj kev txi qhov ceev lossis kev pom tseeb.
