Enqubweni yokukhiqiza imikhiqizo emhlophe yepulasitiki, i-optical brightener iyisengezo esibalulekile.Ukwengeza i-ejenti emhlophe emikhiqizweni yepulasitiki emhlophe kungathuthukisa kakhulu ubumhlophe nokukhanya komkhiqizo, futhi kuthuthukise ngempumelelo ukuncintisana kwemakethe yomkhiqizo.
Kodwa-ke, lapho i-optical brightener ingeziwe, umphumela uba ngcono.Impahla yomkhiqizo wepulasitiki, inqubo yokukhiqiza kanye nezinga lokushisa lokucubungula kuhlukile, futhi inani elingeziwe le-brightener optical nalo lihlukile.
Ngakho-ke, yiziphi izinkinga okufanele zinakwe lapho i-brightener optical isetshenziswa kumapulasitiki, ake sibheke ngezansi.
1. Umthelela wokuba mhlophe we-optical brightenerUmphumela wokuba mhlophe uvamise ukuvezwa ubumhlophe.Ngaphezu kwenani le-optical brightenerused, ubumhlophe buhlobene nokuhambisana nokumelana nesimo sezulu se-resin.I-optical brightener ehambisana kahle nesimo sezulu imelana nomphumela omuhle wokuba mhlophe futhi ihlala isikhathi eside.Ngakho-ke, indlela eqondile nephumelelayo yokuhlola umphumela wokukhanya okhanyayo wezikhanyisi ze-fluorescent ukuhlola ngamasampula amancane.
2. Inani le-optical brighteneradded Inani le-optical brightener ngokuvamile eliphakathi kuka-0.05% no-0.1%, futhi imikhiqizo ngayinye ingase yengezwe ngenani elikhulu.Kodwa-ke, inani le-optical brighteneradded alingcono, kodwa kunomkhawulo othile wokuhlushwa, odlula Inani elithile lomkhawulo, alinawo umphumela wokumhlophe, kodwa ukuphuzi kuzovela.
3. Umthelela wemibalabala emphumeleni omhlophe Ukwenziwa mhlophe kwesibani esikhanyayo umphumela ohambisanayo wokubona, oguqula ukukhanya kwe-ultraviolet kube ukukhanya okuluhlaza okwesibhakabhaka noma okuluhlaza okwesibhakabhaka-violet okubonakalayo ukuze kufezwe injongo yokuba mhlophe.Ngakho-ke, izingxenye ezinomthelela omkhulu ekukhanyeni kwe-optical yizo ezingabamba ukukhanya kwe-ultraviolet, njenge-titanium dioxide, i-ultraviolet absorbers nokunye.I-Anatase titanium dioxide ingamunca u-40% wokukhanya ku-300nm, futhi uhlobo lwe-rutile lungamunca u-90% wokukhanya ku-380nm.Ngokuvamile, uma i-titanium dioxide kanye ne-optical brightenerare isetshenziswa ngesikhathi esifanayo, kungcono ukusebenzisa i-anatase titanium dioxide.Ngokuvamile, lapho ukugxila kokukhanya kwe-optical kufana, ubumhlophe obufinyelelwa lapho kusetshenziswa i-zinc sulfate bukhulu kakhulu, kulandele i-anatase titanium dioxide, futhi i-rutile titanium dioxide ibuthakathaka kakhulu.
4. Umthelela wama-absorber e-ultraviolet I-absorber ye-ultraviolet ingakwazi ukumunca ukukhanya kwe-ultraviolet, kodwa inganciphisa umphumela wokuba mhlophe we-agent emhlophe ye-fluorescent.Ngakho-ke, emikhiqizweni esebenzisa ama-agent amhlophe e-fluorescent, kungcono ukukhetha izinzamisi zokukhanya ze-histamine ezingashintshi umbala.Uma kufanele wengeze isibambisi se-UV, kufanele ukhulise ngokufanelekile inani le-brightener.Ngaphezu kwalokho, izici ezinjengokuthi ingabe okokusebenza kuhlanzekile, ukuhlanzeka kwepulasitiki, kanye nomswakama okuqukethwe konke kunomthelela othile emthelela wokuba mhlophe.
