Optiline Brightener<\/a> on lisandid, mida paberitootjad kasutavad paberi valgemaks ja heledamaks muutmiseks.<\/p>\n

Selleks, et paber n\u00e4eks valgem v\u00e4lja, on oluline lisada paberile aineid, mis nihutavad n\u00e4htamatut ultraviolettkiirguse spektrit<\/a> vahemikus 320-400 nanomeetrit \u00fcle 400 nanomeetri n\u00e4htavale alale. Selle tulemusel muutub paber sinisemaks v\u00f5i fluorestseerub piirkondades, mis on inimsilmale lihtsalt n\u00e4htavad. Kui meie silmad tajuvad seda heledama, sinakasvalge v\u00e4rvusena, siis kolorimeeter<\/a> n\u00e4eb ainult teistsugust sinist v\u00e4rvi. v\u00e4rvim\u00f5\u00f5tmine<\/a> on seet\u00f5ttu optiliste heledamaks muutvate ainete poolt veidi moonutatud, nt loodud profiilid v\u00f5ivad olla kollakad, kuna m\u00f5\u00f5teseade p\u00fc\u00fcab korrigeerida paberi sinakastet.<\/p>\n

Paljud \"valged\" paberid sisaldavad optilisi valgendajaid. M\u00f5nel juhul n\u00f5rgeneb helendav toime suhteliselt l\u00fchikese, mitme aasta jooksul, nii et paberi tarkus kulub \u00e4ra.<\/p>","protected":false},"excerpt":{"rendered":"
