Hais txog cov ntsiab lus tshuaj xws li UV absorbers thiab photostabilizers, ntau tus neeg yuav tsis paub tias lawv yog dab tsi, tab sis yog tias UV absorbers ntxiv rau cov tshuaj pleev thaiv hnub, nws tuaj yeem tiv thaiv peb cov tawv nqaij los ntawm tshav kub, tshav kub, ntau tus neeg yuav tam sim ntawd paub. UV absorber yog dab tsi thiab nws ua li cas. Qhov tseeb, ultraviolet absorbers thiab lub teeb stabilizers tau ntxiv rau hauv cov khoom loj hauv cov khoom siv organic peb siv txhua hnub, tab sis koj tsis paub nws. Cov xim ntawm sab nraud ntawm tsev neeg lub tsheb peb tsav yog feem ntau ntxiv rau cov xim. Nws tuaj yeem tiv thaiv cov xim ntawm lub tsheb los ntawm yellowing, fading, thiab poob ntawm lub teeb. Qee qhov UV absorbers nrog cov khoom tshwj xeeb kuj tseem yuav ntxiv rau thawj txheej ntawm cov yeeb yaj kiab kho qhov muag, uas tuaj yeem thaiv cov teeb meem ultraviolet rays los tiv thaiv peb lub qhov muag ntawm kev puas tsuaj ...
Txij li UV absorbers thiab lub teeb stabilizers tau siv dav thiab muaj cov txiaj ntsig zoo, qhov txawv ntawm lawv yog dab tsi?
Ob qho tib si UV absorbers thiab lub teeb stabilizers yog cov tshuaj ntxiv tseem ceeb los tiv thaiv thiab tswj kev ua haujlwm ntawm cov khoom siv organic, tab sis muaj qee qhov sib txawv hauv lawv txoj haujlwm. Lub ultraviolet absorber tuaj yeem hloov cov teeb meem ultraviolet rays los ntawm nws cov qauv tshuaj tshwj xeeb, hloov cov teeb meem ultraviolet rhuav tshem lub zog rau hauv lub zog tsis muaj cua sov thiab tso tawm, thiab zam lub zog siab ntawm ultraviolet rays los ntawm kev rhuav tshem cov saw hlau molecular ntawm cov khoom siv organic, yog li poob cov polymers. Cov khoom uas cov khoom yuav tsum muaj; thiab lub teeb stabilizer tuaj yeem nkag siab tias yog ib qho khoom pov tseg rau cov teeb meem dawb radicals. Thaum ib co ultraviolet rays tawg los ntawm kev tiv thaiv ntawm lub ultraviolet absorber thiab ua txhaum cov molecular saw ntawm cov organic cov ntaub ntawv, tsim teeb meem polymer dawb radicals, lub teeb stabilizer Nws yog ua tau kom raws sij hawm ntes cov teeb meem dawb radicals mus rau hauv harmless stability me me molecular lug. Feem ntau cov neeg yuav ntxiv UV absorbers thiab lub teeb stabilizers rau cov ntaub ntawv organic hauv ib qho kev faib ua feem, thiab nws cov kev tiv thaiv feem ntau zoo dua li ntawm UV absorbers los yog lub teeb stabilizers ib leeg.
Ultraviolet absorbers thiab lub teeb stabilizers yog cov npe ntawm ob hom khoom, thiab muaj ntau ntau yam sib txawv nyob rau hauv lawv, tsim ib tug loj industrial system. Cov hom tseem ceeb ntawm UV absorbers nyob rau hauv kev ua lag luam muaj xws li benzophenones, benzotriazoles, triazines, thiab lwm yam, uas txawv nyob rau hauv cov nqe lus ntawm UV shielding kev ua tau zoo thiab daim ntawv thov industries; Lub teeb stabilizers kuj yog cov ntsiab lus dav dav, thiab kev lag luam Feem ntau raws li qhov sib txawv ntawm cov qib alkalinity, ntau yam zoo yog tsim, thiab kuj muaj qhov sib txawv ntawm cov hmoov thiab kua hauv cov tsos.
