Silicone-raws li txheej rau PET zaj duab xis
Jun 19, 2023
Silicone cov ntaub ntawv feem ntau yog tsim los ntawm silicon-oxygen chains raws li lub hauv paus txheej txheem chav tsev, thiab sab chains tuaj yeem txuas nrog ntau lwm pawg organic los ntawm silicon atoms. Yog li ntawd, cov qauv muaj ob qho tib si "organic pawg" thiab "inorganic structures". Qhov tshwj xeeb muaj pes tsawg leeg thiab cov qauv molecular ua rau nws sib txuas cov yam ntxwv ntawm cov teeb meem organic thiab kev ua haujlwm ntawm cov teeb meem inorganic.
Silicone coatings feem ntau yog siv los ua cov ntaub ntawv rau pob tshab hnav-resistant txheej vim lawv lub teeb kis tau zoo. Cov txheej txheej no muaj qhov yooj yim txaus thiab kev sib txuas zoo nrog cov khoom siv hauv paus; tsis muaj ob daim ntawv cog lus nyob rau hauv cov saw tseem ceeb, yog li nws tsis yooj yim rau decomposed los ntawm ultraviolet lub teeb thiab ozone, txawm tias nws raug tawm sab nraud los yog nyob rau hauv ib qho chaw uas muaj ozone concentration rau lub sij hawm ntev. Yuav tsis muaj cracking thiab viscous creep, thiab yuav tsis muaj qhov hloov pauv ntawm lub cev thiab hluav taws xob;
Resin-type silicone txheej cov ntaub ntawv yuav tsis daj txawm nyob rau hauv lub zog ultraviolet hluav taws xob, thiab lawv cov xim yuav nyob twj ywm tsis hloov tau ntau xyoo, yog li ntau tus kws tshawb fawb thiab thev naus laus zis tau tshawb fawb hauv cheeb tsam no. Raws li Txheej Txheej Online, yog tias muaj ntau yam ntawm nanoparticles tau nkag mus rau hauv cov txheej txheem, kev hnav tsis kam thiab compactness ntawm txheej tuaj yeem txhim kho ntxiv.
