UV Cov Ntaub Ntawv Txhuam Los Ntawm Xaiv Ruaj Khetilizers
Uv kev nqus spectra ntawm sanduvor vsu
Hnyav: Cyclohexane
Cell: 1.0 cm
Kev siab: 16.8 mg / l
UV nqus
Puag yuav tsum muaj rau kev ua haujlwm UV zoo:
- Lub siab nqus tau nyob rau hauv thaj av UV rhiab
- ua tau zoo dissipation ntawm kev nqus lub zog hauv txoj kev tsis yog-photosensities
(Muaj lub teeb pom kev ruaj khov ntawm UV absorber molecule nws tus kheej)
- High Aunporence nyob rau hauv lub stabilized polymer matrix
(Tsawg tsawg lub cev poob, kev sib raug zoo zoo nrog cov polymer)
- Tsawg heev rhiab rau sab kev tawm tsam nrog / hauv matrix (piv txwv li undesirable stabilitilizer noj, tshem tawm, thiab lwm yam ...)
Thawj xim ntawm UV absorber daws teeb meem
(rau: kev sib cuam tshuam ntawm UV nqus nrog hlau ions)
Lhabaction ntawm UV nqus nrog hlau ions
(qee cov qauv ntxiv xim xim cov xim av lossis khoom siv ua ntej)
