Dab tsi koj yuav tsum paub txog PMMA hauv Digital Coldenistry

Raws li cov chaw tsim khoom tshwj xeeb hauv PMMA thaiv ntau lawm, peb nkag siab txog cov qauv hauv cov chaw ua haujlwm ntev, PMAs}

 

{{01. PMMA Cov Qauv PMMA: Cov Khoom Tshawb Fawb thiab Khoom

🧪 Tshuaj Siv Cov Khoom Siv Tshuaj

PMMA yog ib thermoplastic acrylic polymer muab tau los ntawm methyl methacrylate (c₅h₈o₂)} nws linear molecular qauv muaj:

Siab transparency (lub teeb kis: 92%)

Lub zog tensile: 50-70 mpa

Qhov ceev faj: 1.18 g / cm³ (sib zog dua li zirconia, hnyav dua li ciab)

Thermal Softening taw tes taw tes: 105 degree-inureal rau cad / cam thiab hlawv

✅ biocompatibility & kev nyab xeeb

Muaj ntawv pov thawj nyob rau hauv ISO 10993 rau kev siv Intraoral

Haum rau li 6 lub hlis ntawm kev hnav khaub ncaws

Tsis muaj tshuaj lom thiab tsis muaj kev ywj pheej, ua rau nws muaj kev daws teeb meem zoo rau kev rov qab ib ntus

2. Daim ntawv thov ntawm PMMA rau hauv Kev Kho Hniav

{1. milling siv quav ciab qauv rau casting

PMMA yog ib txoj kev xaiv zoo tshaj rau cov tso quav yeeb tshuaj:

Ntiag tug	PMMA Txawv	Cov qauv ciab
Seem ruaj khov	< ±0.1%	±0.5–1%
Hlawv cov khoom seem	< 0.01 mg/cm²	~ 0.5 mg / cmo

 

Tsis muaj chaw nyob kom huv si

Cov qhov ntev me me txhawb nqa ntev lub sij hawm ua ntej casting

{2. ntev ntev kev rov ua haujlwm ib ntus

15-2012 fawm kib hloov pauv los ntawm ncauj tsev menyuam kom thiaj li yuav rau qhov tob

Lub zog Faj: 85 MPa

FDA-tshem tawm rau kev siv Intraoral siv txog li 6 lub hlis

Tus Neeg Mob Txaus Siab: 89% nyiam multilayer ntau dua ib-ntxoov ntxoo ib cheeb tsam

{3. Digital Ua Haujlwm Kev Sib Xws

PMMA sib txuas sib txuas nrog cov khoom siv kho hniav Digital:

Intraoral scanning raug: ± 20 μm (3shape-siv tau)

MILLING CEEV: 30-45 feeb ib yas-50}}}} sai dua li zirconia

Zoo meej rau cov kev kho hniav tib yam hauv cov chaw kuaj mob nrawm nrawm

🛠 milling cov lus qhia rau kev ua tau zoo tshaj plaws

Tuam Tool Clogging: Txo kom tsawg dua rau 10-15 hli / min

Spindle Ceev: Tsa 20, 000}} - 30, 000 rpm

Clamping: xyuas kom ntau dua lossis sib npaug rau 50 n quab yuam kom tiv thaiv disc ua haujlwm

Cov suab nrov cov suab nrov: Cia siab tias 75-80 dB thaum lub sijhawm milling-li qub vim yog hardness

4. Kev Lag Luam Xav Tau thiab Kev Lag Luam Wholesale

📈 Kev Ua Lag Luam Thoob Ntiaj Teb

Kev lag luam loj: $ 450 lab los ntawm 2028

Cagr: 6.2% (Kev Tshawb Fawb Kev Lag Luam Yav Tom Ntej)

70% ntawm kev kho hniav chav haujlwm tam sim no muab PMMA nyob rau hauv cov haujlwm digital

60% ntawm cov neeg nyob ntawm ib txwm siv rau kev sib tw ua haujlwm-qhov chaw ua kom muaj txiaj ntsig zoo tshaj plaws

Vim li cas thiaj xaiv peb PMA discs

Cov Ntaub Ntawv Muaj Ntawv Pov Thawj: Ntsib ISO 1567 Cov Qauv rau Kev Kho Hniav Acrylics

Hom kev xaiv:

Discs: ø50-100 hli, thickness 10-25 hli

Cov block: tau tshaj tawm nrog Roland, 3Shape, thiab lwm cov khoom loj

Ntau Lawm Muaj Peev Xwm: 10, 000+ discs txhua lub lim tiam

Kev Txhawb Nqa Kev Ua Haujlwm: Xws li kev qhia thiab kev kawm

{{05. kev kuaj tshuaj thiab kev siv tau
