Qhov sib txawv tseem ceeb ntawm kev ntxiv silicone thiab condensation silicone yog qhov sib ntxiv ntawm cov ntaub ntawv silicone los ntawm cov tshuaj tiv thaiv ntxiv, whereas condensation silicone forms los ntawm cov tshuaj tiv thaiv condensation.
Ntxiv cov silicones thiab condensation silicones yog ob hom khoom siv tswv yim. Cov no yog ib qho tseem ceeb hauv cov hniav hlau tshem tau, kev kho tsis ncaj cam khwb cia, matrices rau kev kho tsis ncaj, thiab lwm yam.
Dab tsi yog Ntxiv Silicone?
Ntxiv silicone yog polyvinyl siloxane tsim los ntawm cov tshuaj tiv thaiv ntxiv ntawm silicone elastomer. Cov khoom no tseem muaj npe hu ua poly-vinyl siloxane, vinyl polysiloxane, thiab vinylpolysiloxane. Cov khoom no yog cov kua nplaum uas tuaj yeem ua kom nrawm rau hauv cov khoom zoo li roj hmab. Cov khoom no siv cov duab ntawm txhua qhov chaw uas nws tau dag tawm tsam thaum lub sijhawm kho. Zoo ib yam li ob feem ntawm cov khoom siv epoxy, peb yuav tsum khaws cov kua ob lub ntsiab lus uas peb siv los tsim cov silicone ntxiv rau hauv ob lub raj sib cais kom txog rau thaum lub sijhawm peb sib tov. Qhov no yog vim tias ib zaug peb sib tov, qhov sib tov sib xyaw ua kom tawv sai.
Ntxiv silicone yog dav siv hauv kev kho hniav raws li cov khoom siv pom zoo. Nws kuj tseem muaj txiaj ntsig zoo hauv audiology los coj cov kev xav kom haum rau kev tiv thaiv kev hnov lus lossis kev hnov lus. Tsis tas li ntawd, nws muaj txiaj ntsig zoo hauv kev siv tshuab; Piv txwv li, nws pab nyob rau hauv kev soj ntsuam ntawm sab hauv nta ntawm machined qhov chaw xws li grooves hauv bores, thiab lwm yam.
Cov tshuaj tiv thaiv ntxiv muab cov roj hydrogen nrog rau ntxiv silicone. Yog li ntawd, peb yuav tsum tau tos txog li ib teev ua ntej nchuav cov cam khwb cia rau hauv cov khoom siv silicone ntxiv tom qab nws tsim. Ntxiv mus, thaum npaj cov khoom, peb yuav tsum tau siv qhov yooj yim sib tov ntawm cov xim putty nrog ib tug dawb putty, qhov twg cov tshuaj tiv thaiv pib.
Condensation Silicone yog dab tsi?
Condensation silicone yog hom silicone uas tsim los ntawm cov tshuaj tiv thaiv condensation. Feem ntau, condensation silicones tuaj nyob rau hauv ob pastes. Thawj muab tshuaj yog lub npe hu ua lub hauv paus muab tshuaj txhuam thiab muaj polydimethyl siloxane nrog rau cov muab tub lim thiab xim xim. Qhov thib ob muab tshuaj yog hu ua acceleration paste, thiab nws muaj alkyl silicate, stannous octate, thiab fillers. Tom qab ntawd, peb tuaj yeem sib tov ob lub pastes, uas yog lub sijhawm thaum cov txheej txheem tshuaj pib.
Condensation silicone yog thawj hom silicone impression khoom siv. Cov khoom no tseem hu ua pa silicones. Qhov chaw ntawm cov khoom no feem ntau tshwm sim ntawm chav tsev kub. Yog li ntawd, peb tuaj yeem muab lawv lub npe RTC silicones.
Qhov txawv ntawm Ntxiv Silicone thiab Condensation Silicone yog dab tsi?
Ntxiv cov silicones thiab condensation silicones yog ob hom khoom siv tswv yim. Qhov sib txawv tseem ceeb ntawm qhov sib ntxiv ntawm silicone thiab condensation silicone yog qhov sib ntxiv ntawm cov ntaub ntawv silicone los ntawm cov tshuaj tiv thaiv ntxiv, whereas condensation silicone forms los ntawm cov tshuaj tiv thaiv condensation. Thaum ntxiv silicone yog pliable heev thiab tawv, condensation silicone muaj tsawg yooj thiab me ntsis toughness.
Feem ntau, condensation silicone muaj tus nqi pheej yig dua piv rau cov silicone ntxiv. Dhau li ntawd, ntxiv silicone muab zoo tsis shrinkage thaum condensation silicone muaj ib tug me ntsis degree ntawm shrinkage.
Cov hauv qab no qhia txog qhov sib txawv ntawm qhov sib ntxiv ntawm silicone thiab condensation silicone hauv cov ncauj lus kom ntxaws, hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary - Ntxiv Silicone vs Condensation Silicone
Ntxiv cov silicones thiab condensation silicones yog ob hom khoom siv tswv yim. Cov no yog ib qho tseem ceeb hauv cov hniav hlau tshem tau, tsis ncaj qha cam khwb cia, matrices rau indirect restorations, thiab lwm yam. Qhov tseem ceeb sib txawv ntawm ntxiv silicone thiab condensation silicone yog hais tias ntxiv silicone ntaub ntawv los ntawm ib tug ntxiv tshuaj tiv thaiv, whereas condensation silicone cov ntaub ntawv los ntawm ib tug condensation tshuaj tiv thaiv.
