Hmoov Txhuas Oxide Dawb Hniav 27μm 50μm 90μm 110μm 125μm 250μm Hmoov Sandblasting Hniav
Kev Taw Qhia Txog Hmoov Txhuas Oxide Dawb Hniav
Alumina Dawb Fused rau Kev Siv Sandblasting Hniav yog tsim tshwj xeeb rau kev npaj qhov chaw kom raug hauv cov chaw kuaj hniav. Nws cov duab ntse, kev ntshiab siab, thiab kev faib tawm qhov loj ntawm cov khoom me me ua kom muaj kev ntxuav zoo, tshem tawm oxide, thiab ua kom qhov chaw ntxhib ntawm zirconia, porcelain, hlau crowns, choj, implant abutments, thiab cov khoom siv orthodontic. Los ntawm kev tsim kom muaj qhov chaw sib txuas zoo tagnrho, nws txhim kho kev ua tau zoo ntawm cov nplaum thiab kev kho kom rov qab zoo. Muaj ntau qhov loj me ntawm cov khoom me me, nws sib xws nrog feem ntau cov khoom siv sandblasting hniav thiab cov khoom siv cua, muab kev ua haujlwm blasting ruaj khov nrog cov hmoov av tsawg thiab cov txiaj ntsig zoo sib xws.

1. Cov Hniav Zirconia
Zirconia restorations feem ntau yuav tsum tau sandblasting ua ntej bonding kom nce qhov roughness ntawm qhov chaw, txhim kho kev khaws cia mechanical, thiab txhim kho lub zog ntawm kev sib txuas.
Cov Haujlwm:
Tshem tawm cov kuab paug los ntawm kev ua haujlwm
Ua kom qhov roughness ntawm qhov chaw nce ntxiv
Txhim kho cov pob zeb cement sib txuas
Txhim kho kev ruaj khov mus sij hawm ntev ntawm kev kho dua tshiab
Qhov loj ntawm cov khoom me me uas pom zoo:
30–50 μm (feem ntau siv)
Kev ua haujlwm siab: Kwv yees li 1–2 bar
2. Cov Hlau Crowns & Choj
Siv rau kev kho dua tshiab ua los ntawm cobalt-chromium, nickel-chromium, cov hlau muaj nqis, thiab lwm yam, tom qab casting.
Cov Haujlwm:
Tshem tawm cov txheej oxide
Cov khoom siv ntxiv uas seem tshuav
Txhim kho lub zog ntawm cov hmoov porcelain
Txhim kho kev ua tau zoo ntawm kev sib txuas
Qhov Zoo: Kev txiav zoo ntawm cov corundum dawb; qhov chaw sib xws tom qab xuab zeb blasting, tsis tshua muaj kev ua qias tuaj.
3. Cov Khoom Siv Cog Qoob Loo
Feem ntau yog rau titanium abutments, titanium alloy abutments, thiab lwm yam khoom siv hauv kev kho hniav implant.
Cov Haujlwm:
Ntxuav cov khoom seem uas ua tiav lawm
Ua rau thaj chaw sib txuas ntxiv
Txhim kho lub zog sib txuas ntawm cov resin thiab abutment
Txhim kho kev ruaj khov ntawm kev kho dua tshiab
5. Cov Khoom Siv Kho Hniav Orthodontic
Siv rau kev kho ua ntej ua ntej txuas cov hlau lossis cov khoom siv ceramic.
Cov Haujlwm:
Ua rau qhov roughness ntawm qhov chaw nce ntxiv
Txhim kho lub zog sib txuas ntawm lub bracket thiab nplaum
Txo qhov kev pheej hmoo ntawm kev sib cais
