Silicon Dioxide siv nyob rau hauv kev lag luam yas
Silica tuaj yeem raug siv ua cov khoom ci hauv polyethylene, polypropylene, polybutene, epoxy resin thiab lwm yam yas. Nws tuaj yeem txhim kho lub zog ntawm lub cev thiab hnav ua haujlwm ntawm plastics, zoo li thermal stability ntawm hardness. Lub cable kuj tseem ua tau hluav taws xob rwb thaiv tsev ntawm lub cable, piv txwv li, cov methyl yas silicone roj hmab siab siab kab yog siv cov khoom zoo heev precipitated silica dub. Feem ntau, nws tsis yog yooj yim cais ntawm ob txheej ntawm cov yas zaj duab xis thiab cov hnab ntim, silica yog ib tus neeg tuaj yeem qhib cov khoom siv. Thaum cov tshuaj polyvinyl chloride yog siv cov khoom siv hauv pem teb, yog muaj qee cov pa dawb dub ntxiv lawm, cov khoom ntawm cov khoom tuaj yeem kho, xws li tawv, elasticity, thermal denaturation thiab lwm yam.
