Kev Siv
Tus tshuaj nqus ultraviolet UV-9 yog ib hom hmoov crystalline daj daj lossis dawb, tseem hu ua Sunscreen Agent No. 2 thiab BP-3. Nws haum rau ntau yam yas xws li polyvinyl chloride, polyvinylidene chloride, polymethyl methacrylate, unsaturated polyester, ABS resin, thiab cellulose resin. Nws qhov siab tshaj plaws ntawm qhov nqus tau wavelength yog 280-340 nanometers, nrog rau qhov ntau npaum li cas ntawm 0.1-1.5%. Nws muaj kev ruaj khov zoo thermal thiab tsis lwj ntawm 200 ° C. Cov khoom no tsis tshua nqus lub teeb pom kev, yog li nws haum rau cov khoom xim dawb thiab pob tshab. Nws kuj tseem siv tau rau hauv cov xim thiab cov roj hmab hluavtaws. Ua tus nqus ultraviolet dav dav los ntawm Chemicalbook, nws muaj qhov zoo ntawm kev nqus tau sai, tsis muaj tshuaj lom, tsis muaj teebmeem teratogenic, thiab ruaj khov zoo rau lub teeb thiab cua sov. Tus nqus ultraviolet UV-9 tuaj yeem nqus tau ob qho tib si UV-A thiab UV-B. Nws yog chav kawm Ⅰ tshuaj pleev thaiv hnub pom zoo los ntawm US FDA, thiab feem ntau siv hauv Tebchaws Meskas thiab cov tebchaws European. UV-9 siv dav hauv cov tshuaj pleev thaiv hnub xws li tshuaj pleev thaiv hnub, tshuaj pleev, mis nyuj, emulsions, thiab roj. Nws kuj tseem siv tau ua tus neeg sawv cev tiv thaiv kev hloov xim rau cov khoom uas hloov xim vim yog lub teeb. Tsis tas li ntawd, vim nws sib haum zoo nrog ntau yam yas thiab cov resins, nws feem ntau siv rau ntau qhov chaw xws li PVC thiab unsaturated polyester.
UV absorber UV-9 yog ib qho broad-spectrum UV absorber nrog cov txiaj ntsig xws li kev nqus tau zoo, tsis muaj tshuaj lom, tsis muaj teratogenic effect, thiab ruaj khov zoo rau lub teeb thiab cua sov. Nws tuaj yeem nqus tau ob qho tib si UV-A thiab UV-B. Nws yog Chav Kawm 1 tshuaj pleev thaiv hnub uas tau pom zoo los ntawm US FDA, thiab feem ntau siv hauv Tebchaws Meskas thiab Tebchaws Europe. Nws yog siv dav hauv cov tshuaj pleev thaiv hnub xws li tshuaj pleev thaiv hnub, tshuaj pleev, tshuaj pleev, emulsions, roj, thiab lwm yam, thiab kuj tseem siv tau ua tus neeg sawv cev tiv thaiv kev hloov xim rau cov khoom uas hloov xim vim yog photosensitivity.
Cov tshuaj nqus ultraviolet benzophenone yog cov khoom ruaj khov zoo heev rau cov yas tsim xws li polyethylene, nrog rau qhov ntau npaum li cas ntawm 0.5-1.5%. Lawv kuj tseem siv tau rau hauv kev pleev xim, xim, kev lag luam txheej, paraffin refined, thiab cov tshuaj pleev ib ce txhua hnub.
Nws yog siv rau hauv cov yas, cov tshuaj fibers, xim thiab cov khoom siv roj av, thiab tshwj xeeb tshaj yog rau cov khoom xim dawb thiab pob tshab.
Nws siv tau rau hauv cov xim pleev thiab ntau yam khoom yas, thiab nws zoo tshwj xeeb rau polyvinyl chloride, polyester, acrylic, resin, polystyrene, thiab cov rooj tog xim pob tshab, thiab lwm yam. Nws kuj yog ib qho khoom siv zoo heev rau kev pleev kom zoo nkauj. Qhov ntau npaum li cas yog 0.1-0.5%.
