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 ultraviolet (UV) malamalama, lea e faʻalelei ai mo le televave o lomitusi ma faiga faʻapipiʻi. Oligomers e iai sona sao taua 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 o substrate, le auala faʻamalolo, ma le manaʻoga lelei o le oloa mulimuli.

Epoxy acrylates o oligomers o loʻo i ai vaega epoxy i o 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 maualuga o le iila 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 fa'aitiitia, ma 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 resistance.

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.
