(1) Light shielding agents: These are substances that can shield or reflect ultraviolet rays, preventing light from penetrating into the interior of polymers, thereby protecting polymers. Light shielding agents include inorganic pigments such as carbon black and titanium oxide and organic pigments such as phthalocyanine blue and phthalocyanine green, among which carbon black has the pi bon efè pwoteksyon .
(2) Ultraviolet absorbers: They can effectively absorb ultraviolet rays with a wavelength of 290~410nm, but rarely absorb visible light. They have good thermal stability and light stability. According to their chemical structure, they can be mainly divided into: o-hydroxybenzophenone, Benzotriazole, salisilat, triazin, ak acrylonitrile ranplase . Yo itilize yo ansanm kòm estabilize limyè oksilyè ak anpeche estabilize limyè, espesyalman nan polyolefins oswa penti .}
(3) quenchers: Yo ka aksepte enèji a absòbe pa chromophore a nan plastik la ak gaye enèji a nan fòm lan nan chalè, fluoresans oswa fosforesans, kidonk pwoteje polymère a soti nan domaj pa reyon iltravyolèt . yo gen yon bon efè estabilizasyon sou Polymers ak yo te itilize nan yon ti kras. Kelat Nikèl . Estabilize limyè Nikèl òganik gen bon pèfòmans, men akòz toksisite nan iyon metal lou yo, yo ka ranplase pa lòt moun ki pa toksik oswa ki ba-toksik .
(4) GRATIS Radikal charchaj: Sa a ki kalite estabilizasyon limyè ka pran aktif radikal gratis ki te pwodwi nan Polymers, kidonk inhibition pwosesis la photooxidation ak akonplisman bi pou yo estabilizasyon limyè {{1} Entènasyonalman .
(5) Hydroperoxide dekonpozè: Li se yon kalite anpeche amine limyè estabilizasyon . Radikal, kidonk anpeche degradasyon polymère .
