Cov khoom siv silicone tau paub dav rau lawv cov kev ua tau zoo hauv kev tsim kua muag, lub zog tensile thiab tag nrho cov neeg siv kev paub. Txawm li cas los xij, ntau tus neeg siv khoom ntev tau tshaj tawm txog qhov teeb meem ntawm cov khoom siv silicone - qhov tshwm sim ntawm kev laus, poob ntawm elasticity, thiab nplaum nplaum. Qhov no tuaj yeem ua rau xav tsis thoob, vim tias silicone ib txwm tau xav tias yog cov khoom siv ua haujlwm siab. Yog li, dab tsi ua rau qhov tshwm sim kev laus hauv cov khoom siv silicone?
Silicone resins muaj cov khoom nplaum zoo dua li ntau cov roj hmab, tab sis zoo li ntau lwm cov ntaub ntawv, cov khoom siv silicone kuj tseem muaj kev laus. Qhov no yog vim hais tias sab hauv molecular chains tuaj yeem tawg, ua rau muaj kev hloov pauv tseem ceeb hauv cov khoom lag luam. Tshwj xeeb, cov khoom siv silicone tshwj xeeb yog raug rau lub teeb ultraviolet, uas tuaj yeem ua rau muaj kev puas tsuaj ncaj qha rau cov saw hlau molecular. Cov khoom siv roj hmab tuaj yeem nqus lub teeb lub zog, ua rau tsim cov dawb radicals hauv cov khoom siv. Hauv qhov sib piv, cov khoom siv silicone tsuas tuaj yeem raug puas tsuaj los ntawm cov cuab yeej ntse lossis siv nyob rau hauv ib puag ncig uas tsis tsim nyog rau cov khoom rau lub sijhawm ntev. Txawm tias nyob rau hauv cov xwm txheej tsis zoo, cov khoom siv silicone tseem tuaj yeem siv tau txog li 10 xyoo, thiab qee zaum, txog 100 xyoo.
Txawm li cas los xij, kev raug kub ntev ntev los yog tshuaj lom neeg tuaj yeem ua rau oxidation ntawm cov khoom siv silicone, ua rau kev laus sai. Yog li ntawd, thaum siv cov khoom siv silicone, nws yog ib qho tseem ceeb kom tsis txhob siv lawv nyob rau hauv qhov kub thiab txias, high-pressure, tshuaj lom neeg los yog ozone ib puag ncig rau ncua sij hawm. Los ntawm kev ua cov kauj ruam no, peb tuaj yeem ncua kev laus ntawm cov khoom siv silicone, thaum kawg txuas lawv lub neej.
