Oligomers Fa'aaogaina i le UV Ink Industry

Oligomers o molelaʻau ia e aofia ai ni nai iunite toe fai, ma o vaega autu ia o vaitusi UV curable.UV vaitusi vaitusi o vaitusi e mafai ona faʻamago ma faʻamalolo vave e ala i le faʻaalia i le malamalama ultraviolet (UV), lea e faʻalelei ai mo le televave o lomitusi ma faiga faʻapipiʻi.Oligomers e taua tele le sao i le fuafuaina o meatotino ma le faʻatinoga o vaitusi UV curable, e pei o le viscosity, adhesion, fetuutuunai, tumau, ma le lanu.

E tolu vasega autu o le UV curable oligomers, e pei o epoxy acrylates, polyester acrylates, ma urethane acrylates.O vasega taʻitasi e iai ona uiga ma faʻaoga, e faʻatatau i le ituaiga substrate, le auala faʻamalolo, ma le manaʻoga lelei o le oloa mulimuli.

Epoxy acrylates o oligomers ei ai vaega epoxy i latou tua, ma vaega acrylate i o latou pito.Ua lauiloa i latou mo le maualuga o le gaioiga, maualalo le viscosity, ma le lelei o le tetee atu i vailaau.Ae ui i lea, e iai foʻi a latou faʻafitauli, e pei o le le lelei o le fetuutuunai, maualalo le pipii, ma le samasama.Epoxy acrylates e talafeagai mo le lolomiina i luga o mea faʻamalosi, e pei o uʻamea, tioata, ma palasitika, ma mo talosaga e manaʻomia ai le iila maualuga ma le maaa.

Polyester acrylates o oligomers o loʻo i ai vaega polyester i o latou tua, ma vaega acrylate i o latou pito.Ua lauiloa i latou mo lo latou fa'agaoioiga feololo, fa'aitiitia le fa'aitiitia, ma le fetuutuuna'i lelei.Ae ui i lea, e iai foʻi a latou faʻafitauli, e pei o le maualuga o le viscosity, maualalo le faʻamaʻiina o vailaʻau, ma le manogi manogi.Polyester acrylates e fetaui lelei mo le lolomiina i luga o mea e mafai ona fetuutuunai, e pei o pepa, ata tifaga, ma ie, ma mo talosaga e manaʻomia ai le pipii lelei ma le elasticity.

Urethane acrylates o oligomers o loʻo i ai vaega urethane i o latou tua, ma vaega acrylate i o latou pito.Ua lauiloa i latou mo le maualalo o le gaioiga, maualuga le viscosity, ma sili ona fetuutuunai.Ae ui i lea, e iai foʻi a latou faʻafitauli, e pei o le maualuga o le tau, maualuga le faʻasaina o le okesene, ma le maualalo o le saoasaoa o togafitiga.Urethane acrylates e talafeagai mo le lolomiina i luga o substrates eseese, e pei o laupapa, paʻu, ma paʻu, ma mo talosaga e manaʻomia ai le tumau maualuga ma le abrasion teteʻe.

I le faaiuga, o oligomers e taua mo le faʻatulagaina ma le faʻatinoina o vaitusi faʻamalolo UV, ma e mafai ona faʻavasegaina i vasega autu e tolu, e taʻua o epoxy acrylates, polyester acrylates, ma urethane acrylates.O vasega taʻitasi e iai ona lava lelei ma mea le lelei, e faʻatatau i le faʻaoga ma le mea e fai ai.O le atinaʻeina o oligomers ma le UV ink o se faʻagasologa faifaipea, ma o ituaiga fou o oligomers ma metotia faʻamalolo o loʻo suʻesuʻeina e faʻafetaui ai le faʻateleina o manaʻoga o le pisinisi vaitusi.
