Cov ntawv thov tshwj xeeb rau UV-5411 suav nrog cov txheej txheem (tshwj xeeb tshaj yog cov txheej txheem uas tsis tshua muaj volatility yog qhov txhawj xeeb), cov khoom siv duab, sealants, thiab cov ntaub ntawv elastomeric.
UV 312 yog lub teeb stabilizer zoo heev rau ntau yam yas thiab lwm yam organic substrates suav nrog unsaturated polyesters, PVC (yooj ywm thiab nruj) thiab PVC plastisol.
Cov khoom nqus UV zoo heev rau PVC, PE, PP, ABS & unsaturated polyesters.
Siv rau ntau yam polymers thiab daim ntawv thov suav nrog polyurethanes (Spandex, TPU, RIM thiab lwm yam), engineering plastics (PET, PC, PC/ABS, PA, PBT thiab lwm yam). Muaj kev ruaj khov thermal siab. Muaj cov yam ntxwv zoo heev rau kev nqus lub teeb thiab kev sib raug zoo thiab solubility nrog ntau yam polymers thiab cov kuab tshuaj.
Cov txheej polyurethane ob-component, polyurethane ua npuas ncauj mos thiab polyurethane thermoplastic elastomer, tshwj xeeb hauv cov khoom polyurethane xws li micro-cell ua npuas ncauj, integral daim tawv nqaij ua npuas ncauj, ib txwm ua npuas ncauj tawv ncauj, semi-rigid, ua npuas ncauj mos mos, txheej ntaub, qee cov nplaum, sealants thiab elastomers thiab polyethylenechloride, vinyl polymer xws li acrylic resin muaj kev ruaj khov zoo heev. Nqus tau lub teeb UV ntawm 300 ~ 330nm.
Cov khoom no yog ib qho tshuaj uas yaj tau hauv dej thiab nqus tau cov teeb ci ultraviolet nrog lub spectrum dav thiab qhov siab tshaj plaws ntawm lub teeb-nqus wavelength ntawm 288 nm. Nws muaj qhov zoo ntawm kev nqus tau zoo, tsis muaj tshuaj lom, thiab tsis muaj kev ua xua thiab tsis muaj kev cuam tshuam rau kev puas tsuaj, lub teeb zoo ruaj khov thiab kub ruaj khov thiab lwm yam. Ntxiv mus, nws tuaj yeem nqus tau UV-A thiab UV-B, yog chav kawm I tiv thaiv hnub, ntxiv rau hauv cov tshuaj pleev ib ce nrog cov koob tshuaj ntawm 5-8%.
Benzophenone-4 yog ib yam khoom uas yaj tau hauv dej & pom zoo rau cov yam ntxwv tiv thaiv hnub siab tshaj plaws. Kev sim tau qhia tias Benzophenone-4 ua kom cov gels ruaj khov raws li polyacrylic acid (Carbopol, Pemulen) thaum lawv raug rau UV hluav taws xob. Cov concentration qis li 0.1% muab cov txiaj ntsig zoo. Nws yog siv ua ultra-violet stabilizer hauv cov plaub mos, cov tshuaj pleev ib ce, cov tshuaj tua kab & lithographic phaj txheej. Nws yuav tsum tau sau tseg tias Benzophenone-4 tsis sib xws nrog Mg ntsev, tshwj xeeb tshaj yog hauv cov dej-roj emulsions. Benzophenone-4 muaj xim daj uas dhau los ua ntau dua hauv alkaline ntau yam & tej zaum yuav hloov pauv qhov sib txawv ntawm cov xim daws teeb meem.
BP-2 yog ib feem ntawm tsev neeg ntawm cov benzophenone uas tiv thaiv tau hluav taws xob ultraviolet.
BP-2 muaj kev nqus dej siab hauv thaj chaw UV-A thiab UV-B, yog li ntawd tau siv dav ua lim UV hauv kev lag luam tshuaj pleev ib ce thiab tshuaj lom neeg tshwj xeeb.
Muaj qhov hnyav molecular loj, tsis hloov pauv, tiv taus kev rho tawm; tsim tau yooj yim.
Ib qho benzotriazole UV absorber uas tuaj yeem tiv thaiv kev puas tsuaj ntawm oxidation, tiv thaiv cov khoom siv fiber, thiab txhim kho qib khoom textile; qhov no yog ib tiam tshiab ntawm UV absorbers nrog cov thev naus laus zis patented thiab yeej xyoo 2007 lub xeev-theem tseem ceeb cov khoom pov thawj, ncav cuag theem thoob ntiaj teb.
Cov khoom no tsim nyog rau Polyolefine, Polyvinyl chloride, organic iav thiab lwm yam. Qhov ntev ntawm nthwv dej nqus siab tshaj plaws yog 270-400nm.
Cov khoom no yog cov khoom siv ua kom lub teeb ruaj khov zoo, thiab siv dav hauv cov yas thiab lwm yam organic. Nws muaj peev xwm nqus tau cov hluav taws xob ultraviolet muaj zog thiab tsis tshua muaj kev hloov pauv.
Raws li tus neeg sawv cev nqus ultraviolet, nws muaj rau PVC, polystyrene thiab Polyolefine thiab lwm yam. Qhov siab tshaj plaws absorbing wavelength ntau yog 280-340nm.Qhov kev noj dav dav: 0.1-0.5% rau cov khoom nyias nyias, 0.05-0.2% rau cov khoom tuab.
