UV-9 (BP-3): Ib qho khoom siv tiv thaiv uas nqus tau nthwv dej dav dav, ib qho khoom siv tiv thaiv hnub uas ruaj khov, tiv taus huab cua, thiab tau ntawv pov thawj los ntawm FDA Chav Kawm 1, thiab yog ib qho khoom nqus ultraviolet uas nyiam siv rau cov khoom xim sib dua thiab pob tshab.

Cov tshuaj nqus ultraviolet UV-9 (BP-3, CAS: 131-57-7) yog ib hom tshuaj nqus ultraviolet uas siv benzophenone ua broad-spectrum. Nws yog ib hom tshuaj pleev thaiv hnub Class 1 uas tau txais kev pom zoo los ntawm US FDA, nrog rau ob hom kev nqus ultraviolet. Nws tuaj yeem ntes tau cov teeb ultraviolet hauv 270-340nm, hloov lub zog ultraviolet mus ua lub zog cua sov tsis muaj teeb meem los ntawm kev hloov pauv cov qauv molecular, thiab txo qhov puas tsuaj ntawm cov teeb ultraviolet rau cov khoom siv. Cov khoom no muaj kev ruaj khov photothermal zoo heev, sib xws nrog ntau yam substrates, tsis muaj tshuaj lom, tsis ua rau teratogenic, tsis muaj kev hloov pauv thiab tsis muaj kev hloov pauv, hloov kho rau cov kev xav tau kev tiv thaiv huab cua ntawm cov khoom tsis muaj xim / xim pob tshab, thiab siv dav hauv yas, tshuaj pleev xim, roj hmab, tshuaj pleev thaiv hnub thiab lwm yam teb. Nws yog ib qho kev daws teeb meem tiv thaiv ultraviolet zoo uas sib npaug kev ua tau zoo thiab kev nyab xeeb.

Cov Khoom Tseem Ceeb Zoo:

Kev nqus tau nthwv dej dav dav thiab ua haujlwm tau zoo: Lub ncov nqus tau ncav cuag 288nm thiab 326nm, npog tag nrho 270-340nm ultraviolet band. Nws muaj kev nqus nthwv dej zoo, hloov pauv lub zog ultraviolet sai sai, thiab txo qhov kev pheej hmoo ntawm kev laus ntawm cov khoom siv, daj, thiab poob qhov ci.

Kev ruaj khov zoo heev: Nws muaj lub teeb zoo heev, cua sov, thiab tshuaj lom neeg ruaj khov. Tsis muaj nag lossis lwj hauv kev ua haujlwm kub siab thiab kev siv sab nraum zoov, thiab cov txiaj ntsig tiv thaiv yog ntev thiab ruaj khov.

Muaj peev xwm hloov kho tau zoo rau cov khoom siv hauv qab: Nws muaj kev sib raug zoo heev nrog ntau yam yas, cov resins, thiab cov txheej txheem txheej xws li polyvinyl chloride, polyurethane, thiab acrylic resin, nrog kev sib kis zoo. Nws tsis cuam tshuam rau cov khoom siv lub cev thiab tshuaj ntawm cov khoom hauv qab, thiab tshwj xeeb tshaj yog rau cov khoom xim kaj thiab pob tshab.

Muaj kev nyab xeeb, zoo rau ib puag ncig, thiab ua raws li txoj cai: Nws tsis muaj cov teebmeem teratogenic, tsis tshua muaj kev hloov pauv, thiab tsis tshua muaj kev hloov pauv. Nws ua tau raws li cov qauv kev lag luam hauv Asmeskas thiab European. Nws tsis yog tsuas yog cov khoom siv tshuaj pleev thaiv hnub zoo nkauj uas tau ntawv pov thawj los ntawm FDA tab sis kuj tuaj yeem ua tau raws li cov kev cai tiv thaiv ib puag ncig rau cov ntaub ntawv lag luam.

Kev ua haujlwm siab ntawm daim ntawv thov: Kev ntxiv tsawg tuaj yeem ua tiav kev tiv thaiv zoo, tsis tas yuav kho cov txheej txheem ntau lawm ntxiv, txo cov nqi tag nrho ntawm cov lag luam hauv kev tiv thaiv huab cua.

Siv tau rau ntau thaj teb thiab tag nrho cov xwm txheej:

Vim nws muaj kev ua tau zoo heev, UV-9 (BP-3) siv tau dav hauv plaub lub teb tseem ceeb: cov yas resins, coatings thiab inks, roj hmab hluavtaws, thiab tshuaj pleev thaiv hnub, hloov kho rau cov kev xav tau kev tiv thaiv ultraviolet ntawm ntau yam khoom xim kaj / pob tshab:

Cov yas resins: Kev tiv thaiv kev laus ntawm lub teeb rau cov khoom xws li polyvinyl chloride, polyurethane, polymethyl methacrylate, ABS/AS resins, thiab unsaturated resins.

Cov txheej thiab cov kua mem: Txhim kho qhov tiv taus huab cua ntawm cov xim lag luam, cov xim ntoo, thiab ntau yam kua mem luam ntawv, tiv thaiv cov txheej poob ntawm qhov ci, xim ploj, thiab tawg.

Cov roj hmab hluavtaws: Kev tiv thaiv kev ruaj khov rau ntau yam khoom siv roj hmab hluavtaws, txo qhov tawv thiab tawg vim yog cov duab ultraviolet.

Cov tshuaj pleev thaiv hnub: Cov khoom siv tseem ceeb ntawm cov tshuaj pleev thaiv hnub rau cov tshuaj pleev thaiv hnub, cov tshuaj pleev, cov tshuaj emulsions, cov roj, thiab lwm yam. Nws yog ib qho kev xaiv tseem ceeb hauv kev lag luam Asmeskas thiab European thiab kuj tseem siv tau ua tus neeg sawv cev tiv thaiv xim rau cov khoom lag luam photosensitive.

Tus nqi khoom tseem ceeb:

Nws muab kev tiv thaiv ultraviolet tag nrho lub neej rau cov ntaub ntawv los ntawm kev tsim khoom thiab kev ua mus rau kev siv sab nraum zoov, tiv thaiv cov tsos qub thiab cov khoom siv lub cev ntawm cov khoom xim kaj / pob tshab, ncua cov teeb meem xws li cov khoom siv photodegradation, daj, thiab poob ntawm gloss, thiab txhim kho lub neej tiv taus huab cua thiab kev sib tw ua lag luam ntawm cov khoom. Tib lub sijhawm, nws xav txog qhov kev hloov pauv ntawm cov txheej txheem ntawm kev tsim khoom lag luam thiab kev nyab xeeb ntawm cov ntawv thov kom zoo nkauj, ua tau raws li ob qho kev xav tau ntawm kev tiv thaiv cov ntaub ntawv lag luam thiab tshuaj pleev thaiv hnub txhua hnub hauv ib qho chaw nres tsheb.

Kev Koom Tes thiab Kev Muaj Peev Xwm:

Nrog rau kev daws teeb meem tiv thaiv ultraviolet uas pheej yig, peb txhawb kom cov neeg siv khoom hauv ntau yam lag luam hloov kho lawv cov khoom, feem ntau hloov kho rau qhov xav tau ntxiv ntawm ntau yam kev siv, pab cov khoom tawg los ntawm qhov tsis zoo ntawm kev ua haujlwm tiv taus huab cua, thiab txhim kho kev sib tw tseem ceeb ntawm kev ua lag luam.
