Ii-oligomers ziimolekyuli ezineeyunithi ezimbalwa eziphinda-phindayo, kwaye ziyinxalenye ephambili yee-inki ezinyangekayo zeUV. Iinki ezinyangekayo zeUV zii-inki ezinokomiswa kwaye zinyangeke ngoko nangoko ngokuba sesichengeni sokukhanya kwe-ultraviolet (UV), nto leyo ezenza zibe zezilungele iinkqubo zoshicilelo olukhawulezayo kunye nezokugquma. Ii-Oligomers zidlala indima ebalulekileyo ekumiseleni iipropathi kunye nokusebenza kwee-inki ezinyangekayo ze-UV, ezinje nge-viscosity, ukuncamathela, ukuguquguquka, ukuqina, kunye nombala.
Kukho iiklasi ezintathu eziphambili zeeoligomers ezinyangekayo zeUV, ezizezi, ii-epoxy acrylates, ii-polyester acrylates, kunye ne-urethane acrylates. Iklasi nganye ineempawu zayo kunye nezicelo, kuxhomekeke kuhlobo lwe-substrate, indlela yokunyanga, kunye nomgangatho ofunekayo wemveliso yokugqibela.
I-epoxy acrylates yi-oligomers enamaqela e-epoxy kumqolo wabo, kunye namaqela e-acrylate ekupheleni kwawo. Ziyaziwa ngokusebenza kwazo okuphezulu, i-viscosity ephantsi, kunye nokuchasana kakuhle kweekhemikhali. Nangona kunjalo, bakwanazo ezinye iingxaki, njengokungaguquguquki kakuhle, ukuncamathela okuphantsi, kunye notyekelo lokuba tyheli. I-epoxy acrylates ifanelekile ukuprintwa kwi-substrates eqinile, njengesinyithi, iglasi, kunye neplastiki, kunye nezicelo ezifuna i-gloss ephezulu kunye nobunzima.
I-polyester acrylates yi-oligomers enamaqela e-polyester kumqolo wabo, kunye namaqela e-acrylate ekupheleni kwawo. Baziwa ngokusebenza okuphakathi, ukushwabana okuphantsi, kunye nokuguquguquka okuhle. Nangona kunjalo, bakwanazo ezinye iingxaki, ezifana ne-viscosity ephezulu, ukunganyangeki kweekhemikhali, kunye nokukhutshwa kwevumba. I-polyester acrylates ifanelekile ukuprintwa kwii-substrates eziguquguqukayo, ezifana nephepha, ifilimu, kunye nelaphu, kunye nezicelo ezifuna ukubambelela okulungileyo kunye nokuqina.
I-Urethane acrylates zii-oligomers ezinamaqela e-urethane kumqolo wazo, kunye namaqela e-acrylate ekupheleni kwawo. Baziwa ngokusebenza okuphantsi, i-viscosity ephezulu, kunye nokuguquguquka okugqwesileyo. Nangona kunjalo, bakwanazo ezinye iingxaki, ezifana neendleko eziphezulu, ukuvinjelwa kweoksijini ephezulu, kunye nesantya esisezantsi sokunyanga. I-Urethane acrylates ifanelekile ukuprintwa kwii-substrates ezahlukeneyo, ezifana neenkuni, isikhumba, kunye nerabha, kunye nezicelo ezifuna ukuqina okuphezulu kunye nokuxhatshazwa kwe-abrasion.
Ukuqukumbela, ii-oligomers zibalulekile ekwenziweni nasekusebenzeni kwee-inks ezinyangekayo zeUV, kwaye zinokuhlelwa zibe ziiklasi ezintathu eziphambili, ezizezi epoxy acrylates, iipolyester acrylates, kunye ne-urethane acrylates. Iklasi nganye ineenzuzo zayo kunye nokungonakali, kuxhomekeke kwisicelo kunye ne-substrate. Ukuphuhliswa kwe-oligomers kunye ne-UV inki yinkqubo eqhubekayo, kwaye iintlobo ezintsha ze-oligomers kunye neendlela zokuphilisa zijongwa ukuhlangabezana neemfuno ezikhulayo zeshishini le-inki.
