Hom Phiaj Ntawm Kev Kho Hniav 37% phosphate acid etchant

Kev kho hniav 37% phosphate acid etchant yog qhov tseem ceeb ua ntej-}}}}}}}} ching kev kho mob etching kev kho mob thiab hniav looj tes. Nws cov txiaj ntsig tuaj yeem suav tau raws li hauv qab no:
1. Txuag Etching muaj peev xwm
Sai sai Deminerization: Ib qho kev xav tau ntawm 37% tuaj yeem cuam tshuam hydroxyapatite hauv cov qauv dental nyob hauv 15-30 μ m tob) thiab nce cov txheej txheem sib sib zog nqus.
Uniform etching: Ua tus qauv "Honeycomb zoo li" ntxhib saum npoo (tshwj xeeb rau cov txha hniav ceev), txhim kho lub pob txha hniav kho micro rov qab.
2. Maximizing Adhesive Zog
Qhov kev xaiv zoo tshaj plaws rau kev ua yeeb yam zoo tshaj plaws: Tom qab cov acid etching, thiab lub zog rab dig tuaj yeem ncav cuag 20-30 MPa, uas yog qhov siab dua li tsis siv txhar enamel.
Kev sib xyaw zoo nrog cov teeb meem hluav taws xob: muab kev pom zoo ntub dej thiab cov permeability rau lub teeb uas tau kho cov resins, txo ntug micro teakage.
3. Kho kom meej
Hloov sijhawm siv hloov sijhawm:
Enamel: Pom zoo 15-30 vib nas this (cov hniav txha hniav laus tas mus li yuav siv sijhawm 30 feeb, thaum decidosis hniav yuav ua rau nws).
Kev Kho Hniav: Pom zoo tsawg dua lossis sib npaug li 15 vib nas this (kom tsis txhob muaj kev lom zem heev ua rau muaj kev sib tsoo fiber ntau).
Cov txiaj ntsig ntawm Gel Dosage Daim Ntawv: Cov khoom feem ntau yog nyob rau hauv daim ntawv ntawm cov gel, uas yog ib qho yooj yim kom tsis txhob muaj cov accord a acid etching los ntawm cov kua ntws.
4. Yooj yim rau kev khiav lag luam
Lub cev nrawm tau tuaj yeem txiav tawm cov kev tawm tsam: dej ntws rau 5-10 vib nas this tuaj yeem tshem tawm cov txheej txheem acidinion, thiab ua haujlwm kom nyab xeeb thiab muaj peev xwm.
Tau tshaj ntau cov tshuab ua ke: haum rau txhua cov acid etching koom tes ua ke (xws li "acid etches" thev naus laus zis), siv rau cov khoom noj hniav uas feem ntau thiab thib tsib).
5. Cov chaw kuaj mob ruaj khov
Lub sij hawm ntev depability: lub resin hniav interface tom qab acid corrosion muaj siab ntev}}}}} qhov kev pheej hmoo ntawm kev rov kho dua
Txo cov postoperative rhiab rhiab (thaum siv tsim nyog lub sij hawm ntawm dentin yaig muaj peev xwm zam dhau ntawm cov kws kho hniav thiab txo qhov tshwm sim ntawm cov ntu ntawm cov postoperative rhiab.
6. Kev ruaj ntseg siab
Kev siv cev luv luv yog tsis muaj mob: Thaum siv kom raug, nws muaj qhov tsis zoo ntawm cov hniav hniav (nyab xeeb thaum tseem tshuav ntawm cov hniav cuav yog loj dua 0.5mm).
Tsawg residual kev pheej hmoo: Tom qab ua kom huv si yaug, tsis muaj cov khoom seem qub acidic, uas tsis cuam tshuam rau kev ua kom tiav.
