UV 312 yog lub teeb pom kev zoo rau ntau yam yas thiab lwm cov organic substrates nrog rau cov polyesters tsis muaj zog, PVC (hloov thiab nruj) thiab PVC plastisol.
Ua tau zoo UV absorber rau PVC, PE, PP, ABS & unsaturated polyesters.
Siv rau ntau yam polymers thiab daim ntaub ntawv xws li polyurethanes (Spandex, TPU, RIM thiab lwm yam), engineering plastics (PET, PC, PC / ABS, PA, PBT thiab lwm yam).Muab siab thermal stability.Muab zoo heev lub teeb absorbing yam ntxwv thiab zoo compatibility thiab solubility nrog ntau yam polymers thiab cov kuab tshuaj..
Polyurethane ob txheej txheej, polyurethane mos ua npuas ncauj thiab polyurethane thermoplastic elastomer, tshwj xeeb tshaj yog nyob rau hauv cov khoom polyurethane xws li micro-cell ua npuas ncauj, ib qho ntawm daim tawv nqaij ua npuas ncauj, ib txwm rigid ua npuas ncauj, semi-rigid, mos ua npuas ncauj, ntaub txheej, ib co adhesives, sealants thiab elastomers thiab polyethylenechloride, vinyl polymer xws li acrylic resin muaj lub teeb ruaj khov zoo heev.Absorbing UV teeb ntawm 300 ~ 330nm.
Cov khoom no yog cov dej-soluble ultraviolet hluav taws xob-absorbing tus neeg saib xyuas nrog lub dav spectrum thiab lub siab tshaj plaws lub teeb-absorbing wavelength ntawm 288nm. , zoo teeb ruaj khov thiab kub stability thiab lwm yam. Ntxiv mus, nws muaj peev xwm nqus tau UV-A thiab UV-B, yog chav kawm I hnub tiv thaiv tus neeg saib xyuas, ntxiv rau hauv cov tshuaj pleev ib ce nrog ntau npaum li cas ntawm 5-8%.
Benzophenone-4 yog dej-soluble & raug pom zoo rau lub hnub tiv thaiv ntau tshaj plaws.Cov kev ntsuam xyuas tau pom tias Benzophenone-4 stabilizes viscosity ntawm gels raws li polyacrylic acid (Carbopol, Pemulen) thaum lawv raug UV hluav taws xob.Concentrations tsawg li 0.1% muab cov txiaj ntsig zoo.Nws yog siv los ua ultra-violet stabilizer hauv wool, tshuaj pleev ib ce, tshuaj tua kab & lithographic phaj txheej.Nws yuav tsum raug sau tseg tias tBenzophenone-4 tsis sib haum nrog Mg ntsev, tshwj xeeb tshaj yog nyob rau hauv dej-roj emulsions.Benzophenone-4 muaj xim daj uas dhau los ua ntau dua hauv cov alkaline ntau & tuaj yeem hloov pauv vim yog xim xim.
BP-2 belongs rau tsev neeg ntawm hloov benzophenone uas tiv thaiv ultraviolet hluav taws xob.
BP-2 muaj qhov nqus tau zoo hauv thaj tsam UV-A thiab UV-B, yog li tau siv dav hauv UV lim hauv kev lag luam tshuaj pleev ib ce thiab tshuaj tshwj xeeb.
Muaj qhov hnyav molecular, tsis yog-volatile, tsis kam muab rho tawm;tsim tau yooj yim.
benzotriazole UV absorber uas tuaj yeem cuam tshuam oxidation degradation cov tshuaj tiv thaiv, tiv thaiv cov khoom siv fiber ntau, thiab txhim kho cov khoom textile qib;qhov no yog ib tiam tshiab ntawm UV absorbers nrog patented technology thiab yeej 2007 lub xeev cov khoom tseem ceeb ntawv pov thawj, mus txog thoob ntiaj teb qib.
Cov khoom no yog tsim rau hauv Polyolefine, Polyvinyl chloride, organic iav thiab lwm yam.Max nqus nthwv dej ntev yog 270-400nm.
Cov khoom no yog high-efficiency lub teeb stabilizing tus neeg saib xyuas, thiab dav siv nyob rau hauv yas thiab lwm yam organics.Nws muaj zog ultraviolet hluav taws xob nqus muaj peev xwm thiab tsis tshua muaj hluav taws xob.
Raws li tus neeg saib xyuas ultraviolet absorption, nws muaj rau PVC, polystyrene thiab Polyolefine thiab lwm yam. Qhov max absorbing wavelength ntau yog 280-340nm.Qhov dav siv: 0.1-0.5% rau cov teeb meem nyias, 0.05-0.2% rau cov khoom tuab.
