Kunezinhlobo eziningi zeama-fluorescent whitening agents, futhi afanelekele imikhiqizo ehlukahlukene ye-fiber futhi anokusetshenziswa okuningi okuhlukile imithamo.Nakuba ukwakheka kwamakhemikhali nokusebenza kwezinhlobo ezahlukene zama-ejenti amhlophe e-fluorescent kuhlukile, izimiso zokumhlophe zemikhiqizo enjengemicu ziyefana.
Njengoba i-ejenti emhlophe ye-fluorescent ingumkhiqizo omhlophe, kungani ukusetshenziswa kakhulu kwendwangu ngeke kuyenze ibe mhlophe futhi kubangele ukumhlophe kwehle?I-molecule ye-agent emhlophe ye-fluorescent iqukethe isistimu yebhondi ephindwe kabili ehlanganisiwe, enokuhlelwa okuhle.Lesi sakhiwo samangqamuzana esikhethekile singamunca imisebe ye-ultraviolet engabonakali ngaphansi kokukhanya kwelanga, ngaleyo ndlela ibonise futhi ikhiphe ukukhanya okuluhlaza okwesibhakabhaka-violet, futhi ekugcineni ibe sendwangu yefiber.Ihlanganiswe nokukhanya okuphuzi, ikhipha ukukhanya okumhlophe okubonakala ngeso lenyama, ukuze kuzuzwe umphumela wokukhipha okuphuzi nokumhlophe.
Umgomo oyinhloko okhanyayo wama-optical brighteners uwukuthiukukhanya okukhanyayo, hhayi ukushibilika kwamakhemikhali okukhiqiza ukusabela kwamakhemikhali.Ngakho-ke, ngaphambi kokusebenzisa ama-optical brighteners ezindwangu, ukuxubha amakhemikhali afanele kungenza ukukhanya okukhanyayo kusebenze.Umthelela omkhulu.Okuqukethwe kwemisebe ye-ultraviolet ekukhanyeni kwelanga okukhanyiswe endwangu kanye nokugxila kwe-ejenti emhlophe ye-fluorescent engutsheni kuchazwa ngokomgomo wokuba mhlophe we-ejenti emhlophe.Amaphuzu amabili angenhla anquma umthelela omhlophe we-agent ekhanyayo ye-optical engutsheni.
Uma okuqukethwe kwe-UV ekukhanyeni kwelanga kwanele, ukugxila kwe-ejenti emhlophe ye-fluorescent engutsheni kungaphakathi kwebanga elisebenzayo, futhi umphumela wokuba mhlophe womkhiqizo uyanda njengoba ukugxila kwe-ejenti emhlophe ye-fluorescent kukhuphuka.Uma ukugxiliswa kwe-ejenti emhlophe ye-fluorescent kufinyelela izinga elithile elilungile endwangu, umphumela wokuba mhlophe ungcono kakhulu, futhi inani eliphezulu lobumhlophe elingafinyelelwa umkhiqizo wamanje lingatholwa.Uma ukugxila kokukhanya kwe-fluorescent kudlula inani elibalulekile elingase lisetshenziswe umkhiqizo wendwangu yamanje, ubumhlophe bendwangu buzophenduka buphuzi noma bubonise ngisho nombala wokuqala wesibani.Ngakho-ke ukugxila okuphelele okusetshenziswe kwendwangu kubizwa ngokuthi iphoyinti eliphuzi le-brightener.Pho kungani ubumhlophe buncipha uma inani le-brightener elisetshenziswe kwendwangu likhulu kakhulu?
Lapho ukugxila kokukhanya kwe-fluorescent emkhiqizweni wendwangu kufinyelela endaweni ephuzi ye-brightener, ukuqina kokukhanya okuluhlaza okwesibhakabhaka okuboniswa yi-brightener kanye nokukhanya okuphuzi kwendwangu kuyahambisana, futhi umphumela okhanyayo ungcono kakhulu lesi sikhathi se.Futhi lapho ukugxila kudlula iphuzu eliphuzi le-brightener, ukukhanya okuluhlaza okwesibhakabhaka okuluhlaza okwedlulele kudlula ukukhanya okuphuzi kwendwangu, okuholela ekukhanyeni okweqile okuluhlaza okwesibhakabhaka-violet, futhi into yokugcina iso elinqunu eliyibonayo ukwehla okuphawulekayo kobumhlophe noma ngisho. okuphuzi.
Ngakho-ke, ngaphambi kokwengeza isibani se-fluorescent emkhiqizweni, amasampula aqhubekayo kufanele athathwe ukuze kuhlolwe iphuzu eliphuzi lohlobo lwamanje lokukhanyisa ezindwangu nakweminye imikhiqizo.Ukuze kulungiswe inani eliphelele lesengezo ukuze kwandiswe umphumela wokuba mhlophe.
