Lapho uvikela izinto ezisetshenziswayo kanye nemikhiqizo emiphumeleni eyingozi yokukhanya kwelanga, kunezithasiselo ezimbili ezivame ukusetshenziswa: ama-Absorbent we-UV kanyeama-stabilizers alula. Nakuba zizwakala zifana, lezi zinto ezimbili empeleni zihluke kakhulu endleleni ezisebenza ngayo kanye nezinga lokuvikela ezikunikezayo.

Njengoba igama lisho, ama-absorber ama-UV amunca imisebe ye-ultraviolet (UV) evela elangeni. Imisebe ye-UV yaziwa ngokudala ukuwohloka kwezinto eziningi, ikakhulukazi lezo ezichayeka elangeni isikhathi eside. Ama-absorber ama-UV asebenza ngokumunca imisebe ye-UV futhi ayiguqule ibe ukushisa, okube sekuchithwa ngokungenangozi.

Ngakolunye uhlangothi, ama-photostabilizers asebenza ngokuvimbela ukuwohloka kwezinto okubangelwa imisebe ye-ultraviolet nokukhanya okubonakalayo. Ama-absorber ama-UV agxila kuphela ekuvikelekeni emisebeni ye-UV, kuyilapho ama-photostabilizer enikeza ukuvikeleka okubanzi. Abagcini nje ngokumunca imisebe ye-UV, baphinde babambe ama-radicals mahhala akhiqizwa ukuchayeka ekukhanyeni okubonakalayo.

Indima yeama-stabilizers alulaiwukunciphisa ama-radicals mahhala futhi uwavimbele ekulimazeni izinto. Lokhu kubenza baphumelele ikakhulukazi ekubambezeleni inqubo yokuwohloka kwezinto ezivame ukuvezwa ezindaweni zangaphandle. Ngokuvimbela ukwakheka kwama-radicals mahhala, iziqinisi zokukhanya zisiza ukunweba impilo yezinto ezibonakalayo futhi zigcine ubuqotho bayo besakhiwo.

Ukwengeza, ama-stabilizers okukhanya avame ukuhlanganiswa nawoAma-Absorbers we-UVukunikeza isivikelo esiphelele emiphumeleni elimazayo yelanga. Ngenkathi ama-Absorbers e-UV abhekana kakhulu nemithelela yemisebe ye-UV, ama-photostabilizer engeza isendlalelo esengeziwe sokuvikela ngokukhipha ama-radicals mahhala akhiqizwa ukukhanya okubonakalayo. Ngokusebenzisa izithasiselo zombili ndawonye, ​​okokusebenza kuvikelwa kuhlu olubanzi lwamaza amaza ayingozi.

Omunye umehluko phakathi kwe-UV absorbers kanyeama-stabilizers alulaisicelo sabo nokuhambisana nezinto ezahlukene. Ama-absorbers e-UV avame ukusetshenziswa ekugqokeni okucacile, amafilimu nama-polymers ngoba aklanyelwe ukuba abonakale futhi angathinti ukubukeka kwezinto. Iziqinisi ezikhanyayo, ngakolunye uhlangothi, ziguquguquka futhi zingasetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, okuhlanganisa amapulasitiki, irabha, upende, nezindwangu.

Ekuphetheni, nakuba kokubili ama-Absorbers we-UV nama-photostabilizers asetshenziselwa ukuvikela izinto ekonakalisweni okubangelwa ukukhanya kwelanga, ayahluka endleleni yawo yokwenza kanye nezinga lokuvikela. Izimunca ze-UV zimunca imisebe ye-UV, kuyilapho ama-photostabilizer avimbela ukuwohloka okubangelwa imisebe ye-UV nokukhanya okubonakalayo ngokwenza ama-radicals mahhala abe lula. Ngokuqonda umehluko phakathi kwalezi zithako, abakhiqizi bangakhetha inketho efanelekile kakhulu yesicelo sabo esithile futhi baqinisekise ukuvikelwa okungcono kakhulu kwezinto zabo.
