Chinonyudza UV
Pasi pezuva nechiedza chezuva uye fluorescence, mapurasitiki nezvimwe zvinhu zvepolymer zvinoitwa otomatiki oxidation reaction pasi pesimba remwaranzi ye ultraviolet, izvo zvinotungamira mukuora kwema polymer uye kuora kwechitarisiko uye hunhu hwemakanika. Mushure mekunge ultraviolet absorber yawedzerwa, mwaranzi ye ultraviolet ine simba guru inogona kunyudzwa nenzira yakasarudzwa uye kushandurwa kuita simba risingakuvadzi kuti riburitswe kana kudyiwa. Nekuda kwemhando dzakasiyana dzema polymer, ma wavelength e ultraviolet anoaparadza akasiyanawo. Ma ultraviolet absorber akasiyana anogona kunyudza mwaranzi ye ultraviolet ine ma wavelength akasiyana. Pakushandisa, ma ultraviolet absorbers anofanirwa kusarudzwa zvichienderana nerudzi rwema polymers.
Zvinonyudza UV zvinogona kukamurwa kuita mhando dzinotevera zvichienderana nechimiro chazvo chemakemikari: salicylates, benzones, benzotriazoles, substituted acrylonitrile, triazine nezvimwe.
