Nuuxiyaha ultraviolet (UV absorber) waa xasiliye iftiin ah oo nuugi kara qaybta ultraviolet ee iftiinka qoraxda iyo ilayska fluorescent isaga oo aan is beddelin.Nuugista Ultraviolet inta badan waa budada crystalline cad, xasilloonida kulaylka wanaagsan, xasilloonida kiimikada wanaagsan, aan midab lahayn, aan sun ahayn, ur la'aan, guud ahaan loo isticmaalo polymers (caaga, iwm.), dahaarka iyo wixii la mid ah.

Inta badan midabada, gaar ahaan midabada midabka aan organic, waxay ciyaari karaan heer gaar ah oo xasilinta iftiinka marka keligood loo isticmaalo alaabta caaga ah.Alaabooyinka caaga ah ee midabka leh ee loogu talagalay isticmaalka dibadda ee muddada-dheer, xasilloonida iftiinka alaabta laguma hagaajin karo midabeeyaha oo keliya.Kaliya isticmaalka xasiliyaha iftiinka ayaa si wax ku ool ah u joojin kara ama hoos u dhigi kara heerka gabowga iftiinka ee alaabta caagga ah ee midabka leh muddo dheer.Si weyn u wanaaji xasilloonida iftiinka alaabta caaga ah ee midabka leh.Amine light stabilizer (HALS) waa nooc ka mid ah xeryahooda aminiga organic oo leh saameyn adag.Sababtoo ah hawlaheeda kala-goynta hydroperoxide, deminta ogsijiinta xagjirka ah, dabinnada xagjirka xorta ah, iyo dib-u-warshadaynta kooxaha wax ku oolka ah, HALS waa xasiliye nalka caagga ah oo leh waxtar sare oo ka-hortagga sawir-qaadista iyo qaddarka ugu badan ee gudaha iyo dibaddaba.Xogtu waxay muujineysaa in xasilinta iftiinka ku habboon ama nidaamka isku dhafka habboon ee antioxidant iyo xasilinta iftiinka ay hagaajin karto xasilloonida iftiinka iyo oksijiinta alaabta caagga ah ee midabka dibadda ah dhowr jeer.Alaabooyinka balaastiigga ah ee midabada leh ee sawir-qaadista iyo sawir-qaadista (sida cadmium jaalaha ah, rutile aan la daboolin, iwm.), iyadoo la tixgelinayo saameynta sawir-qaadista catalytic ee midabaynta, qadarka xasilinta iftiinka waa in la kordhiyaa si waafaqsan.

Uv absorbers guud ahaan waxaa loo kala saari karaa iyadoo loo eegayo qaab dhismeedka kiimikada, jajabka ficilka iyo isticmaalka, kuwaas oo lagu sifeeyay hoos:

1.Classification iyadoo loo eegayo qaab-dhismeedka kiimikada: nuugayaasha ultraviolet waxaa loo qaybin karaa nuugayaasha ultraviolet organic iyo nuuga ultraviolet inorganic.Nuugayaasha ultraviolet-ka dabiiciga ah waxaa ka mid ah benzoates, benzotriazole, cyanoacrylate, iwm.

2.Classification iyadoo loo eegayo habka ficilka: nuuga ultraviolet waxaa loo qaybin karaa nooca gaashaanka iyo nooca nuugista.Xiidiyeyaasha UV-ga waxay awoodaan inay ka tarjumayaan iftiinka UV sidaas darteedna waxay ka hortagayaan inuu galo jirka, halka nuugayaasha UV ay awoodaan inay nuugaan iftiinka UV oo u beddelaan kulayl ama iftiin muuqda.

3.Classification marka loo eego isticmaalka: nuugista ultraviolet waxa loo qaybin karaa darajada qurxinta, heerka cuntada, fasalka dawooyinka, iwm Alaabooyinka baakadaha, iyo kuwa wax nuugaya ee heerka dawada ee UV ayaa inta badan lagu isticmaalaa daawooyinka.
