Emasimini okukhiqiza kanye nesayensi yezezimali, ukuphishekela ukuthuthukisa ukukhanga ngobuhle nokusebenza kwemikhiqizo akupheli. Ukusungulwa okukodwa okuthola ukugcwala okukhulu ukusetshenziswa kwezimpawu zokukhanya, ikakhulukazi kumapulasitiki. Kodwa-ke, umbuzo ojwayelekile ovela ukuthi kungaba ukubhekisisa oku-Optical kufana ne-bleach. Lo mbhalo uhlose ukudiliza la magama futhi uhlole imisebenzi yabo, izinhlelo zokusebenza, kanye nokwehluka.
Kuyini ukucwaswa kwe-optical?
Izimpawu zokubona, eyaziwa nangokuthi ama-agents amhlophe amhlophe (FWA), amakhompiyutha amunca ukukhanya (UV) ukukhanya (UV) ukukhanya futhi wakukhipha kabusha njengokukhanya okuluhlaza okwesibhakabhaka. Le nqubo yenza lokho kubonakale kumhlophe futhi kuqhakaze esweni lomuntu. Izimpawu zokubona zisetshenziswa ezinhlobonhlobo zezimboni, kufaka phakathi izindwangu, okokuhlanza kanye namapulasitiki.
Endabeni yamapulasitiki, iziqu zokukhanya zengezwa ngesikhathi sokukhiqiza ukuze kuthuthukiswe isikhalazo sokubuka komkhiqizo wokugcina. Zisiza kakhulu ekwenzeni izinto zepulasitiki zibukeke zihlanzekile futhi zinempilo, zinxephezele noma yikuphi ukuphuzi noma ukuncipha okungenzeka ngokuhamba kwesikhathi.
Kusebenza kanjani abaqhakaza be-Optical?
Isayensi ngemuva kwabasiki be-optical banezimpande zayo ku-fluorescence. Lapho ukukhanya kwe-ultraviolet kushaya ingaphezulu kwemikhiqizo yepulasitiki equkethe iziqu zeplastiki, i-compound inquma ukukhanya kwe-ultraviolet futhi iphinde iyenze kabusha ukukhanya okuluhlaza okwesibhakabhaka. Lokhu kukhanya okuluhlaza okwesibhakabhaka kukhansula noma yiluphi u-tint ophuzi, okwenza ukubukeka kwepulasitiki okumhlophe futhi kube namandla.
Ukusebenza kweIzimpawu zokubonaKuya ngezici eziningana, kufaka phakathi uhlobo lweplastiki, ukugcwala kokuqhakaza, kanye nokwakhiwa okuthile kwe-compound. Ukulimala okujwayelekile okusetshenziselwa amapulasitiki kufaka phakathi ama-stilbene derivatives, ama-coumarins kanye ne-benzoxazoles.
Ukusetshenziswa kwama-fluorescent whitening agents kumapulasitiki
Izimpawu zokukhanya zisetshenziswa kabanzi emikhiqizweni yepulasitiki, kufaka phakathi:
1. Izinto zokupakisha: yenza ukupakishwa okubonakalayo ngokwengeziwe futhi kuthuthukise ukubukeka komkhiqizo ngaphakathi.
2. Izinto zasendlini: njengeziqukathi, izitsha, ifenisha, njll. Gcina ukubukeka okuhlanzekile nokugqamile.
I-3. Izingxenye ze-Auto: Thuthukisa ama-aesthetics ezingxenyeni ezingaphakathi nezingaphandle.
4. I-Electronics: Qinisekisa ukubukeka okubandayo, kwanamuhla ekuhlolweni kwezindlu nezinye izinto.
Ingabe ukufunwa kokukhanya kuyafana ne-bleach?
Impendulo emfushane ayikho; Izimpawu zokukhanya kanye ne-bleach azifani. Ngenkathi bobabili besetshenziselwa ukuthuthukisa ukubukeka kwezinto ezibonakalayo, basebenza ngezindlela ezihluke ngokuphelele futhi basebenze ngezinhloso ezahlukahlukene.
Kuyini i-bleach?
I-Bleach iyindawo yamakhemikhali esetshenziselwa ukubiza ukubulala amagciwane kanye nezakhiwo ezimhlophe. Izinhlobo ezivame kakhulu ze-bleach ziyi-chlorine bleach (sodium hypochlorite) kanye ne-oxygen bleach (i-hydrogen peroxide). I-Bleach isebenza ngokuphula amabhondi zamakhemikhali phakathi kwamabala nemibala, ukususa ngempumelelo umbala ezintweni zokwenziwa.
Umehluko Osemqoka phakathi kokuthuthuka okubonakalayo kanye ne-bleach
1. Indlela Yokusebenza:
- Ukuqhakaza kwe-Optical: kwenza izinto zokwenziwa zibonakale zimhlophe futhi zikhanye ngokuthola imisebe ye-UV futhi zizikhiphe kabusha njengokukhanya okuluhlaza okwesibhakabhaka.
- I-Bleach: isusa umbala kusuka ezintweni zokwehla ngamakhemikhali amabala nemibala.
2. Inhloso:
- Ama-ejenti amhlophe amhlophe e-Fluorescent: Kusetshenziswe ngokuyinhloko ukuthuthukisa isikhalazo sezinto ezibonakalayo ngokwenza ukuthi zivele zihlanzekile futhi zinempilo.
- I-Bleach: Isetshenziselwa ukuhlanza, ukulimalisa amagciwane kanye nokususwa kwamabala.
3. Isicelo:
- I-Fluorescent Whitening Agent: Isetshenziswa kakhulu kumapulasitiki, izindwangu kanye nezinsimbi.
- I-Bleach: Isetshenziswa emikhiqizweni yokuhlanza indlu yasendlini, okokuhlanza izingubo nezihlanza izimboni.
4. Ukwakheka kwamakhemikhali:
- Ama-ajenti amhlophe amhlophe e-Fluorescent: I-Organic Compounds enjengeStilbene Derivatives, Coumisarins kanye neBenzoxazoles.
- I-Bleach: Amakhompiyutha e-Inorganic afana ne-sodium hypochlorite (chlorine bleach) noma amakhompiyutha ezi-organic afana ne-hydrogen peroxide (i-oxygen bleach).
Ukuphepha nokucatshangelwa kwemvelo
Izimpawu zokubonaFuthi ama-bleach ngamunye anezinkinga zawo zokuphepha nezemvelo. Ukuxinwa kwe-Optical ngokuvamile kubhekwa njengokuphephile ukuze kusetshenziswe kwimikhiqizo yabathengi, kepha kukhona ukukhathazeka ngokuphikelela kwabo emvelweni kanye nemiphumela engaba khona entameni yasemanzini. I-Bleach, ikakhulukazi i-chlorine bleach, iyacekelwa phansi futhi ikhiqiza imikhiqizo emibi efana ne-dioxins, eyingozi empilweni yabantu kanye nemvelo.
Ekuphetheni
Yize ukuthuthuka okubonakalayo kanye ne-bleach kungahle kubonakale kufana ngenxa yemiphumela yakwamhlophe, izindlela zabo, izinhloso zabo, kanye nezinhlelo zokusebenza zihlukile ngokuyisisekelo. Izimpawu zokukhanya ziyizinhlanganisela ezikhethekile ezisetshenziselwa ukuthuthukisa isikhalazo esibonakalayo samapulasitiki nezinye izinto ngokuzenza zibonakale zimhlophe futhi ziqhakaze. Ngokuphambene nalokho, i-bleach iyisicoci esinamandla esisetshenziselwa ukususa amabala nezindawo zokubulala amagciwane.
Ukuqonda lo mehluko kubalulekile kubakhiqizi, abathengi, nanoma ngubani obandakanyeke kwi-Material Science noma ukuthuthukiswa komkhiqizo. Ngokukhetha i-compact efanelekile yesicelo esifanele, singafinyelela imiphumela ethandekayo yobuhle futhi sisebenze ngenkathi sinciphisa imiphumela emibi empilweni nasendaweni yemvelo.
