Optical brighteners, e tsejoang hape e leli-optical lighteners(OBAs), ke metsoako e sebelisoang ho ntlafatsa ponahalo ea thepa ka ho eketsa bosoeu le khanya.Hangata li sebelisoa liindastering tse fapaneng, ho kenyelletsa le masela, pampiri, li-detergents le polasetiki.Sehloohong sena, re tla hlahloba hore na li-optical brighteners ke life, hore na li sebetsa joang, le mefuta e fapaneng ea ts'ebeliso ea tsona.

Lisebelisoa tse khanyang li sebetsa ka ho monya leseli la ultraviolet (UV) le ho le ntša hape e le khanya e bonahalang maboneng a blue-violet.Ketsahalo ena e bitsoa fluorescence.Ka ho fetola mahlaseli a UV hore e be leseli le bonahalang, li-optical brighteners li ntlafatsa ponahalo le thepa ea fluorescent, e etsa hore e bonahale e khanya le ho soeufala.

Tšebeliso e tloaelehileng ea li-optical brighteners ke indasteri ea masela.Ka masela, li-optical brighteners li eketsoa masela le likhoele ho ntlafatsa ponahalo ea tsona ea pono.Ha liaparo kapa masela a tšetsoeng ka li-optical brighteners a pepesehetse khanya ea letsatsi kapa khanya ea maiketsetso, a monya mahlaseli a teng a UV 'me a ntša khanya e bonahalang, e leng se etsang hore masela a bonahale a soeufala le ho feta.Phello ena e lakatseha ka ho khetheha ho masela a masoeu kapa a bobebe, a ntlafatsang bohloeki le bocha ba bona.

Indasteri e 'ngoe e sebelisang li-optical brighteners haholo ke indasteri ea pampiri.Li-lighteners tsa optical li eketsoa nakong ea tlhahiso ea pampiri ho eketsa khanya ea eona le ho etsa hore e bonahale e le tšoeu.Ka ho eketsa bosoeu ba pampiri,li-optical lightenersthusa ho hlahisa litšoantšo le litšoantšo tsa boleng bo holimo.Li boetse li thusa ho fokotsa palo ea enke e hlokahalang bakeng sa khatiso, e leng ho fellang ka ho baballa litšenyehelo bakeng sa lik’hamphani tsa khatiso le bareki.

Li-optical brighteners le tsona li atisa ho fumanoa ka li-detergents.Li kenyellelitsoe ho liforomo tsa sesepa ho etsa hore bosoeu bo bonahale bo le bosoeu le mebala e khanyang haholoanyane.Ha liaparo li hlatsuoa ka li-detergent tse nang le li-optical brighteners, metsoako ena e kenngoa ka holim'a lesela, e monya mahlaseli a ultraviolet le ho ntša leseli le leputsoa, ​​​​ho pata 'mala o mosehla le ho ntlafatsa khanya ea liaparo ka kakaretso.Sena se etsa hore liaparo li lule li hloekile ebile li le ncha, esita le ka mor'a hore li hlatsoe hangata.

Holim'a moo,li-optical lightenersli boetse li sebelisoa ho etsa polasetiki.Li kenngoa ka polasetiki nakong ea ts'ebetso ea tlhahiso ho ntlafatsa ponahalo ea eona le ho etsa hore e shebahale e khahleha haholoanyane.Lihlahisoa tsa polasetiki tse kang libotlolo, lijana le lisebelisoa tsa ho paka tse tšoaroang ka li-optical brighteners li bonahala li khanya ebile li khahleha ka lishelefong tsa mabenkele.Ho sebelisa li-optical brighteners ka li-plastiki ho ka boela ha thusa ho pata mefokolo leha e le efe kapa mosehla o ka hlahang ha nako e ntse e ea ka lebaka la ho pepesehela mahlaseli a letsatsi kapa maemo a tikoloho.

Ka kakaretso, li-optical brighteners ke metsoako e sebelisoang haholo liindastering tse fapa-fapaneng ho ntlafatsa bosoeu le khanya ea thepa.Ka ho monya leseli la ultraviolet le ho le ntša hape e le leseli le bonahalang, li-optical brighteners li thusa ho ntlafatsa ponahalo ea masela, pampiri, li-detergents le polasetiki.Li bohlokoa ho fihlela litšoaneleho tse ntle le tsa temoho tse hlokahalang ho lisebelisoa tsena.Ho sa tsotellehe hore na ho etsa hore masela a shebahale a hloekile haholoanyane, lipampiri tsa pampiri li shebahala li le bohale, kapa li-plastiki li shebahala li khahleha haholoanyane, li-optical brighteners li phetha karolo ea bohlokoa ho ntlafatsa phihlelo ea pono ka kakaretso.
