Kub kub silicone, raws li cov khoom siv dav siv, yog dav siv hauv kev lag luam xws li hluav taws xob, khoom siv, tsheb, kev kho mob, thiab kev tsim kho. Txawm li cas los xij, cov lus nug ntawm seb qhov kub ntawm silicone yuav yaj puas xav kom peb muaj kev nkag siab tob txog cov khoom, cov yam ntxwv, thiab kev ua tau zoo ntawm silicone nyob rau hauv ib puag ncig kub.
Ua ntej, cia peb nkag siab txog cov yam ntxwv ntawm silicone. Silicone yog ib qho elastomer ua los ntawm cov ntaub ntawv xws li silica thiab hydrated silicates. Nws muaj qhov ua tau zoo ntawm qhov kub thiab txias, tshuaj lom neeg ruaj khov, thiab kev ua haujlwm rwb thaiv tsev, thiab yog li siv dav hauv ntau qhov chaw kub kub. Cov khoom tseem ceeb ntawm silicone yog siloxane, thiab Si-O daim ntawv cog lus hauv nws cov saw molecular muab silicone tshwj xeeb lub cev thiab tshuaj lom neeg.
Txawm li cas los xij, txawm hais tias silicone muaj qhov kub thiab txias, nws tuaj yeem ua rau qee qhov kev hloov pauv hauv qhov kub thiab txias. Lub melting point ntawm silicone feem ntau yog siab tshaj 200 degrees Celsius, tab sis qhov tshwj xeeb melting point nyob ntawm tus qauv thiab kev tsim cov txheej txheem ntawm silicone. Hauv kev siv cov tswv yim, silicone feem ntau tuaj yeem tswj nws qhov qub elasticity thiab ruaj khov ntawm qhov kub siab dua.
Kev ua haujlwm ntawm silicone ntawm qhov kub thiab txias yog feem ntau cuam tshuam los ntawm ob yam: ua ntej, muaj pes tsawg leeg ntawm silicone, thiab cov khoom sib txawv ntawm silicone muaj cov khoom sib txawv ntawm qhov kub thiab txias; Qhov thib ob, qhov hardness thiab formula ntawm silicone kuj tuaj yeem cuam tshuam nws txoj kev ruaj ntseg hauv qhov kub thiab txias.
Nyob rau hauv qhov kub thiab txias, silicone feem ntau nthuav tawm cov khoom zoo antioxidant, uas tuaj yeem tiv thaiv oxidation tshwm sim. Txawm li cas los xij, raws li qhov kub thiab txias ntxiv, cov qauv molecular ntawm silica gel tuaj yeem hloov pauv, ua rau muaj kev hloov pauv hauv nws lub cev. Nyob rau hauv cov huab cua kub kub, silicone yuav soften, poob nws thawj elasticity thiab stability.
Tsis tas li ntawd, cov xim ntawm silicone kuj tuaj yeem cuam tshuam los ntawm qhov kub thiab txias. Qee cov silicone gels uas muaj cov organic dyes los yog pigments tej zaum yuav muaj fading los yog discoloration ntawm qhov kub thiab txias, uas muaj feem xyuam rau stability ntawm dyes los yog pigments nyob rau hauv lub kub kub.
Txhawm rau tiv thaiv qhov kub thiab txias ib puag ncig zoo dua, qee cov tuam ntxhab kuj tau tsim cov khoom siv hluav taws xob kub-resistant silicone, uas muaj cov ntsiab lus melting ntau dua thiab kev ua haujlwm kub zoo dua. Qhov kub-resistant silicone no feem ntau siv cov mis tshwj xeeb thiab cov txheej txheem kev npaj kom muaj kev ua tau zoo tshaj qhov dav ntawm qhov kub thiab txias.
Zuag qhia tag nrho, high-temperature silicone exhibits kev ua tau zoo heev nyob rau hauv ib tug tej yam kub thiab txias, tab sis tej zaum yuav raug ib co kev hloov nyob rau hauv cov huab cua kub. Yog li ntawd, hauv kev siv cov tswv yim, nws yog ib qho tsim nyog yuav tau xaiv cov khoom tsim nyog ntawm silicone raws li kev siv ib puag ncig, thiab xyuam xim rau nws qhov ntsuas kub tsis kam. Tsis tas li ntawd, kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntawm cov khoom siv silicone kuj tseem ceeb txhais tau tias kom ntseeg tau tias lawv cov kev ua haujlwm ruaj khov. Los ntawm kev xaiv cov khoom tsim nyog thiab tsim nyog thiab kev tswj xyuas kev siv, kev ua haujlwm zoo ntawm cov khoom siv silicone tuaj yeem siv tau zoo dua, ua kom nws daim ntawv thov kev nyab xeeb thiab txhim khu kev qha hauv ntau qhov chaw.
