Li-oligomers ke limolek'hule tse nang le likarolo tse 'maloa tse iphetang,' me ke likarolo tse ka sehloohong tsa li-inks tse phekolehang tsa UV. Li-inks tse phekolehang tsa UV ke li-inks tse ka omisoang le ho phekoloa hang-hang ka ho pepesehela khanya ea ultraviolet (UV), e leng se etsang hore e be tse loketseng ts'ebetso ea ho hatisa le ho koahela ka lebelo le phahameng. Li-oligomers li bapala karolo ea bohlokoa ho khethollang thepa le ts'ebetso ea li-inks tse phekolehang tsa UV, joalo ka viscosity, adhesion, tenyetseha, ho tšoarella le 'mala.
Ho na le lihlopha tse tharo tsa mantlha tsa li-oligomers tse phekolehang tsa UV, e leng li-epoxy acrylates, polyester acrylates le urethane acrylates. Sehlopha se seng le se seng se na le litšobotsi le ts'ebeliso ea sona, ho latela mofuta oa substrate, mokhoa oa ho phekola, le boleng bo lakatsehang ba sehlahisoa sa ho qetela.
Li-epoxy acrylates ke li-oligomers tse nang le lihlopha tsa epoxy mokokotlong oa tsona, le lihlopha tsa acrylate lipheletsong tsa tsona. Li tsebahala ka reactivity ea tsona e phahameng, viscosity e tlase, le khanyetso e ntle ea lik'hemik'hale. Leha ho le joalo, ba boetse ba na le litšitiso tse ling, joalo ka ho se tenyetsehe hantle, ho khomarela ho tlase, le tšekamelo ea ho ba mosehla. Li-acrylate tsa epoxy li loketse ho hatisoa holim'a li-substrates tse thata, tse kang tšepe, khalase le polasetiki, le bakeng sa lisebelisoa tse hlokang khanya e phahameng le ho thatafala.
Polyester acrylates ke li-oligomers tse nang le lihlopha tsa polyester mokokotlong oa tsona, le lihlopha tsa acrylate lipheletsong tsa tsona. Li tsebahala ka ho etsa lintho ka mokhoa o itekanetseng, ho honyela ho fokolang, le ho fetoha habonolo ha tsona. Leha ho le joalo, li boetse li na le litšitiso tse ling, joalo ka viscosity e phahameng, khanyetso e tlase ea lik'hemik'hale, le ho tsoa monko o monate. Li-acrylate tsa polyester li loketse ho hatisoa holim'a li-substrates tse tenyetsehang, tse kang pampiri, filimi le lesela, le bakeng sa lisebelisoa tse hlokang ho khomarela hantle le elasticity.
Urethane acrylates ke li-oligomers tse nang le lihlopha tsa urethane mokokotlong oa tsona, le lihlopha tsa acrylate lipheletsong tsa tsona. Li tsebahala ka ho reactivity e tlase, viscosity e phahameng, le ho feto-fetoha ha maemo ho hoholo. Leha ho le joalo, li boetse li na le litšitiso tse ling, tse kang theko e phahameng, thibelo e phahameng ea oksijene, le lebelo le tlaase la ho phekola. Li-acrylates tsa Urethane li loketse ho hatisoa holim'a li-substrates tse fapaneng, tse kang lehong, letlalo le rabara, le bakeng sa lisebelisoa tse hlokang ho tšoarella ho phahameng le ho hanyetsa abrasion.
Qetellong, li-oligomers li bohlokoa bakeng sa tlhahiso le ts'ebetso ea li-inks tse phekolehang tsa UV, 'me li ka aroloa ka lihlopha tse tharo tse kholo, e leng epoxy acrylates, polyester acrylates, le urethane acrylates. Sehlopha se seng le se seng se na le melemo le melemo ea sona, ho itšetlehile ka kopo le substrate. Nts'etsopele ea li-oligomers le enke ea UV ke ts'ebetso e tsoelang pele, 'me mefuta e mecha ea li-oligomers le mekhoa ea ho phekola e ntse e hlahlojoa ho fihlela litlhoko tse ntseng li eketseha tsa indasteri ea enke.
