Isifunxi se-UV
Phantsi kwelanga kunye ne-fluorescence, iiplastiki kunye nezinye izinto ze-polymer zenza i-oxidation reaction ngokuzenzekelayo phantsi kwesenzo semitha ye-ultraviolet, nto leyo ekhokelela ekuwohlokeni kwee-polymers kunye nokuwohloka kwembonakalo kunye neempawu zoomatshini. Emva kokuba i-ultraviolet absorber yongeziwe, imitha ye-ultraviolet enamandla aphezulu inokufunxwa ngokukhetha kwaye iguqulwe ibe ngamandla angenabungozi ukuze ikhutshwe okanye idliwe. Ngenxa yeentlobo ezahlukeneyo zee-polymers, ubude be-ultraviolet obuziwohlozayo nabo bahlukile. Ii-ultraviolet absorbers ezahlukeneyo zinokufunxwa imitha ye-ultraviolet enemitha ye-wavelengths eyahlukeneyo. Xa usebenzisa, ii-ultraviolet absorbers kufuneka zikhethwe ngokweentlobo zee-polymers.
Izifunxi ze-UV zinokwahlulwa zibe ziintlobo ezilandelayo ngokwesakhiwo sazo seekhemikhali: ii-salicylates, ii-benzones, ii-benzotriazoles, ii-acrylonitrile ezitshintshiweyo, ii-triazine kunye nezinye.
