Ts'ebetsong ea tlhahiso ea lihlahisoa tsa polasetiki tse tšoeu, optical brightener ke tlatsetso e hlokahalang.Ho kenyelletsa moemeli o mosoeu ho lihlahisoa tsa polasetiki tse tšoeu ho ka ntlafatsa haholo bosoeu le ho khanya ha sehlahisoa, 'me ka katleho ho ntlafatsa tlhōlisano ea' maraka ea sehlahisoa.
Leha ho le joalo, ha khanya ea optical e eketsoa haholoanyane, phello e ba betere.Thepa ea sehlahisoa sa polasetiki, ts'ebetso ea tlhahiso le mocheso oa ts'ebetso li fapane, 'me palo ea tlatsetso ea khanya ea optical le eona e fapane.
Kahoo, ke mathata afe a lokelang ho lefshoa ha optical brightener e sebelisoa ka polasetiki, a re hlahlobeng ka tlase.
1. Tšusumetso e soeufalang ea optical brightenerTlhahiso e soeufetseng hangata e bontšoa ke bosoeu.Ntle le palo ea optical brightenerused, bosoeu bo boetse bo amana le ho lumellana le ho hanyetsa boemo ba leholimo ba resin.The optical brightener e tsamaisanang hantle le boemo ba leholimo bo hanyetsanang le boemo ba leholimo bo na le phello e ntle ea bosoeu ebile e tšoarella nako e telele.Ka hona, mokhoa o tobileng le o sebetsang oa ho lekola phello e tšoeu ea li-fluorescent lighteners ke ho etsa liteko ka lisampole tse nyane.
2. Palo ea optical brighteneradded Palo ea optical brightener ka kakaretso e pakeng tsa 0.05% le 0.1%, 'me lihlahisoa tsa motho ka mong li ka eketsoa ka bongata bo boholo.Leha ho le joalo, palo ea optical brighteneradded ha e molemo, empa ho na le moeli o itseng oa mahloriso, o fetang Moeli o itseng oa boleng, ha o na phello e tšoeu feela, empa ho tla hlaha mosehla.
3. Tšusumetso ea li-pigments ka phello e tšoeu Ho soeufala ha khanya ea optical ke phello e tlatsetsang ea optical, e fetolang leseli la ultraviolet hore e be leseli le bonahalang le leputsoa kapa le putsoa-violet ho finyella morero oa ho soeufala.Ka hona, likarolo tse nang le tšusumetso e kholo ho khanya ea optical ke tse khonang ho monya leseli la ultraviolet, tse kang titanium dioxide, li-absorber tsa ultraviolet joalo-joalo.Anatase titanium dioxide e ka monya 40% ea leseli ho 300nm, 'me mofuta oa rutile o ka monya 90% ea khanya ho 380nm.Ka kakaretso, haeba titanium dioxide le optical brightenerare li sebelisoa ka nako e le 'ngoe, ho molemo ho sebelisa anatase titanium dioxide.Ka kakaretso, ha mahloriso a khanya ea optical a tšoana, bosoeu bo finyelloang ha ho sebelisoa zinc sulfate ke bo matla ka ho fetisisa, bo lateloa ke anatase titanium dioxide, le rutile titanium dioxide e fokolang ka ho fetisisa.
4. Tšusumetso ea li-absorber tsa ultraviolet Mokelikeli oa ultraviolet o ka monya leseli la ultraviolet, empa o ka fokotsa phello e soeufalang ea fluorescent whitening agent.Ka hona, lihlahisoa tse sebelisang li-fluorescent whitening agents, ho molemo ho khetha histamine light stabilizers tse sa fetoleng 'mala.Haeba o tlameha ho eketsa sehlaseli sa UV, o lokela ho eketsa ka nepo palo ea khanya.Ho phaella moo, lintlha tse kang hore na lisebelisoa tsa ho lokisa li hloekile, ho hloeka ha polasetiki, le mongobo kaofela li na le tšusumetso e itseng ho phello e tšoeu.
