IiOligomers ezisetyenziswa kwi-UV Ink Industry

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 kweultraviolet (UV), nto leyo ezenza zibe zezilungele inkqubo yoshicilelo olukhawulezayo neyokugquma.Ii-Oligomers zidlala indima ebalulekileyo ekumiseleni iipropati 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 kakuhle 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.
