Plastiki e sebelisoa haholo liindastering tse fapaneng ka lebaka la ho feto-fetoha ha eona le theko e tlase.Leha ho le joalo, bothata bo tloaelehileng ba li-plastiki ke hore li atisa ho ba mosehla kapa ho senya nako ka lebaka la ho pepesehela khanya le mocheso.Ho rarolla bothata bona, bahlahisi ba atisa ho eketsa lisebelisoa tse bitsoang optical brighteners lihlahisoa tsa polasetiki ho ntlafatsa ponahalo ea tsona.

E boetse e tsejoa e leli-optical lighteners, li-optical brighteners ke metsoako e monyang khanya ea ultraviolet le ho ntša leseli le leputsoa, ​​​​e thusang ho pata bosehla kapa ho fetoha ha 'mala ka polasetiki.Lisebelisoa tsena tse soeufatsang li sebetsa ka ho fetola mahlaseli a sa bonahaleng a UV hore e be leseli le bonahalang le leputsoa, ​​​​ho etsa hore polasetiki e bonahale e le tšoeu le ho khanya mahlong a motho.

E 'ngoe ea li-optical brighteners tse sebelisoang ka ho fetisisa ka li-plastiki ke motsoako oa tlhaho o bitsoang triazine-stilbene derivative.Motsoako ona o sebetsa hantle haholo ho monyang mahlaseli a UV le ho ntša leseli le leputsoa, ​​​​ho etsa hore e be se loketseng bakeng sa ho ntlafatsa ponahalo ea polasetiki.

Plastikili-optical lightenerstla ka mefuta e mengata, ho kenyeletsoa phofo, li-liquid le li-masterbatches, e leng likaroloana tse koalehileng tse qhalakantsoeng ka har'a resin ea sejari.Mefuta ena e fapaneng e ka kenngoa habonolo ts'ebetsong ea tlhahiso ea polasetiki, ho etsa bonnete ba hore khanya e ajoa ka ho lekana ho pholletsa le sehlahisoa se felileng.

Ntle le ho ntlafatsa ponahalo ea lipolasetiki, li-optical brighteners li fana ka melemo e meng, joalo ka ho fana ka ts'ireletso ea UV le ho ntlafatsa ts'ebetso eohle ea thepa.Ka ho monya mahlaseli a kotsi a UV, li-whitener li thusa ho lelefatsa bophelo ba polasetiki ka ho thibela ho senyeha le ho ba mosehla ho bakoang ke ho pepesehela UV.

Holim'a moo,li-optical lightenerse ka kopanngoa le li-additives tse ling, tse kang UV stabilizers le antioxidants, ho etsa lihlahisoa tsa polasetiki tse hanyetsanang le maemo a tikoloho le ho boloka ponahalo ea tsona ka nako.

Ha li sebelisoa ka nepo, li-lighteners tsa polasetiki tsa optical li ka ntlafatsa haholo boleng le boleng ba lihlahisoa tsa polasetiki liindastering tse ngata ho kenyelletsa ho paka, thepa ea bareki, likoloi le kaho.Ka ho kenyelletsa li-additives tsena mefuteng ea bona ea polasetiki, bahlahisi ba ka etsa bonnete ba hore lihlahisoa tsa bona li boloka boipiletso ba pono le ho tšoarella esita le ka mor'a ho pepesehela nako e telele ho khanya le maemo a tikoloho.

Ke habohlokoa ho hlokomela, leha ho le joalo, hore khetho le mahloriso ali-optical lightenerse tlameha ho lekanngoa ka hloko ho fihlela phello e lakatsehang ntle le ho ama hampe ts'ebetso kapa litšobotsi tsa polasetiki.Tšebeliso e feteletseng ea li-whitener li ka fella ka ponahalo e boputsoa haholo kapa e seng ea tlhaho, athe tšebeliso e tlase e ka 'na ea se ke ea sebetsa ho pata ho senyeha.

Ka bokhutšoanyane, li-optical brighteners li phetha karolo ea bohlokoa ho ntlafatsa ponahalo le ts'ebetso ea polasetiki.Ha tlhokahalo ea lihlahisoa tsa polasetiki tsa boleng bo holimo, tse bonahalang li ntse li eketseha, tšebeliso eali-optical lightenerse lebelletsoe ho eketseha, ho khanna boqapi le tsoelo-pele lebaleng la li-additives tsa polasetiki.Ka ho sebelisa melemo ea metsoako ena, bahlahisi ba ka etsa li-plastiki tse sa shebahaleng hantle feela, empa hape li tšoarella nako e telele ebile li tšoarella.
