Silicone Hydrogels VS Silicones: Qhov txawv tseem ceeb thiab kev siv
Hauv kev nthuav dav ntawm cov ntaub ntawv tshawb fawb, silicone hydrogels thiab silicones yog ob qho khoom tseem ceeb polymer, txhua tus muaj cov khoom sib txawv thiab kev siv dav.
Kev sib xyaw thiab cov qauv
Silicone: Silicone yog ib qho khoom siv tsis zoo hauv polymer feem ntau tsim los ntawm silicon dioxide (SiO2). Cov khoom siv no muaj cov qauv ntxeem tau thiab ntau pawg hydrophilic, uas tso cai rau nws nqus thiab khaws cov dej noo, organic compounds, thiab inorganic ntsev. Silicone tus qauv ruaj khov ua rau nws tiv taus tshuaj lom neeg, muab lub hauv paus ruaj khov rau nws cov ntawv thov hauv ntau yam.
Silicone Hydrogel: Hauv qhov sib piv, silicone hydrogel yog cov khoom siv organic ua los ntawm polysiloxane tebchaw thiab dej molecules. Nws zoo nkaus li pob tshab, mos, tsis muaj tshuaj lom, tsis muaj ntxhiab, thiab tsis muaj xim zoo li gel, zoo ib yam li cov khoom ib nrab zoo li jelly. Cov yam ntxwv tshwj xeeb ntawm silicone hydrogel nyob hauv nws cov khoom siv biphasic, suav nrog cov fluorosilicone thiab hydrogel raws. Cov qauv no txhim kho nws lub peev xwm nqus, ruaj khov, thiab biocompatibility.
Cov yam ntxwv ua haujlwm
Silicone: Silicone nthuav tawm cov cua kub zoo heev, tshuaj tiv thaiv corrosion, thiab hluav taws xob rwb thaiv tsev, nrog rau zoo elasticity thiab sealing peev xwm. Cov khoom zoo no ua rau silicone siv dav hauv kev lag luam xws li kev tsim khoom, hluav taws xob, tshuaj, thiab kev ua zaub mov. Txawm li cas los xij, silicone feem ntau tsis siv rau hauv cov khoom uas tuaj yeem sib cuag ncaj qha nrog tib neeg lub cev lossis tsiaj txhu, kom tsis txhob muaj teeb meem biocompatibility.
Silicone Hydrogel: Lub tsev ntawm qhov zoo ntawm silicone, silicone hydrogels ntxiv txhim khu biocompatibility thiab nqus. Qhov no ua rau silicone hydrogel tshwj xeeb tshaj yog haum rau kev siv hauv kev kho mob thiab tshuaj pleev ib ce. Tsis tas li ntawd, silicone hydrogels muaj cov pa oxygen permeability siab, uas yog tshwj xeeb tshaj yog muaj txiaj ntsig zoo hauv kev tiv thaiv lo ntsiab muag, qhov uas lawv ua tau zoo dua cov khoom siv hydrogel, muab cov neeg hnav kom zoo dua thiab noj qab nyob zoo.
Daim ntawv thov
Silicone: Silicone muaj ntau yam kev siv, npog kev lag luam xws li kev tsim khoom, chemistry, metallurgy, electronics, textiles, pharmaceuticals, thiab zaub mov. Hauv cov ntawv thov kev lag luam, silicone yog siv rau cov ntsaws ruaj ruaj, gaskets, thiab cov ntaub ntawv vibration-damping; nyob rau hauv electronics, nws yog siv rau encapsulating thiab insulating Cheebtsam; thiab hauv kev lag luam tshuaj, silicone yog siv los tsim cov khoom siv kho mob thiab cov khoom siv dag zog.
Silicone Hydrogel: Silicone hydrogels feem ntau yog siv rau hauv kev kho mob, tshuaj pleev ib ce, thiab zaub mov kev lag luam. Hauv cov tshuaj, silicone hydrogel yog siv los ua cov tshuaj tiv thaiv kab mob thiab kev cog hniav ntawm lub mis, ntawm lwm yam khoom. Hauv kev lag luam tshuaj pleev ib ce, nws yog siv rau hauv cov khoom zoo nkauj xws li lub ntsej muag lub ntsej muag. Hauv kev lag luam khoom noj khoom haus, silicone hydrogel tuaj yeem siv rau hauv cov tshuaj adsorption thiab tswj kev tso tawm. Tsis tas li ntawd, silicone hydrogels tau pom muaj peev xwm ua tau zoo hauv cov khoom siv thev naus laus zis xws li kev sib cais kev lom neeg, kev ua kom huv, thiab microfluidic chip manufacturing.
