Cov yam ntxwv tseem ceeb ntawm silicone:
Silicone yog ib qho polymer compound polymerized los ntawm silica, uas muaj elasticity zoo heev, kub tsis kam, rwb thaiv tsev kev ua tau zoo, thiab tshuaj stability. Cov yam ntxwv no ua rau nws yog ib qho ntawm cov khoom nyiam hauv ntau qhov chaw. Txawm li cas los xij, nws yog qhov tseeb vim tias cov yam ntxwv no uas silicone muaj qhov tseem ceeb dua rau qhov kub thiab txias.
Kev hloov pauv ntawm silicone ntawm qhov kub thiab txias:
Silicone feem ntau nthuav tawm cov cua kub zoo heev ntawm qhov kub thiab txias, tab sis raws li qhov kub nce, nws cov elastic modulus maj mam txo qis, ua rau tsis muaj zog ntawm nws elasticity. Cov txheej txheem no feem ntau yog vim muaj kev hloov pauv hauv cov qauv molecular ntawm silica gel, qhov twg cov qauv kev cog lus yuav cuam tshuam los ntawm thermal zog thiab tawg lossis xoob. Yog li ntawd, lub sij hawm ntev raug rau huab cua kub ib puag ncig tuaj yeem ua rau txo qis hauv cov khoom siv ntawm silicone, thiab txawm tawg thiab deform.
Kev hloov pauv ntawm silicone ntawm qhov kub thiab txias:
Contrary to high temperatures, silicone kuj muaj qee qhov brittleness ntawm qhov kub thiab txias. Nyob rau hauv qhov kub tsis tshua muaj kub, silicone yuav ua nyuaj heev, poob nws elasticity thiab yooj. Qhov no yog vim tias qhov kub qis tuaj yeem ua rau cov qauv molecular ntawm silicone ua nruj dua, yog li txo nws cov elasticity tag nrho. Nyob rau hauv qhov kub thiab txias ib puag ncig, silicone yuav raug cuam tshuam rau sab nraud thiab rupture, yog li yuav tsum ceev faj thaum siv cov khoom siv silicone hauv cov huab cua txias.
Melting thiab decomposition kub ntawm silicone:
Silicone muaj qhov kub melting thiab decomposition kub. Feem ntau hais lus, lub melting kub ntawm silicone yog siab tshaj 200 degrees Celsius, thaum lub decomposition kub yog siab dua. Txawm li cas los xij, hauv cov ntawv thov, peb feem ntau tsis ua kom sov silicone rau qhov kub siab heev vim tias txawm tias qhov kub thiab txias tsis tuaj yeem ncav cuag, qhov ntev ntev ntawm qhov kub thiab txias yuav muaj kev cuam tshuam tsis zoo rau kev ua haujlwm ntawm silicone.
Cov tswv yim rau silicone gel los tiv thaiv qhov kub thiab txias:
Nws yog ib qho tseem ceeb heev uas yuav tau siv kev tiv thaiv kom ua tau zoo tshaj plaws ntawm silicone, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig uas muaj qhov kub thiab txias hloov. Piv txwv li, nyob rau hauv qhov chaw kub kub, ntsuas kub dissipation tuaj yeem ua kom tsis txhob muaj cua sov ntau dhau ntawm silicone. Nyob rau hauv qhov chaw txias, qhov kub tsis kam ntawm cov khoom siv silicone tuaj yeem txhim kho los ntawm kev ua kom lawv softness.
