Oligomers yog cov molecules uas muaj ob peb qhov rov ua dua, thiab lawv yog cov khoom tseem ceeb ntawm UV curable inks. UV curable inks yog inks uas tuaj yeem qhuav thiab kho tam sim ntawd los ntawm kev raug ultraviolet (UV) lub teeb, uas ua rau lawv zoo tagnrho rau kev kub ceev luam ntawv thiab txheej txheej txheej. Oligomers ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab cov khoom thiab kev ua haujlwm ntawm UV curable inks, xws li viscosity, adhesion, yooj, durability, thiab xim.
Muaj peb chav kawm tseem ceeb ntawm UV curable oligomers, uas yog epoxy acrylates, polyester acrylates, thiab urethane acrylates. Txhua chav kawm muaj nws tus yam ntxwv thiab kev siv, nyob ntawm seb hom substrate, txoj kev kho, thiab qhov xav tau zoo ntawm cov khoom kawg.
Epoxy acrylates yog oligomers uas muaj epoxy pawg hauv lawv cov caj qaum, thiab pawg acrylate ntawm lawv qhov kawg. Lawv paub txog lawv cov reactivity siab, tsis tshua muaj viscosity, thiab cov tshuaj tiv thaiv zoo. Txawm li cas los xij, lawv kuj muaj qee qhov tsis zoo, xws li kev ua haujlwm tsis zoo, tsis tshua muaj adhesion, thiab yellowing nyiam. Epoxy acrylates yog tsim rau kev luam ntawv ntawm cov txheej txheem nruj, xws li hlau, iav, thiab yas, thiab rau cov ntawv thov uas xav tau siab gloss thiab hardness.
Polyester acrylates yog oligomers uas muaj pawg polyester hauv lawv cov caj qaum, thiab pawg acrylate ntawm lawv qhov kawg. Lawv paub txog lawv qhov nruab nrab reactivity, tsawg shrinkage, thiab zoo saj zawg zog. Txawm li cas los xij, lawv kuj muaj qee qhov tsis zoo, xws li siab viscosity, tsis tshua muaj tshuaj lom neeg, thiab tsw emission. Polyester acrylates yog tsim rau kev luam ntawv ntawm cov khoom siv yooj yim, xws li ntawv, zaj duab xis, thiab ntaub, thiab rau cov ntawv thov uas xav tau adhesion zoo thiab elasticity.
Urethane acrylates yog oligomers uas muaj urethane pawg hauv lawv cov pob txha, thiab pawg acrylate ntawm lawv qhov kawg. Lawv paub txog lawv qhov qis reactivity, siab viscosity, thiab zoo heev yooj. Txawm li cas los xij, lawv kuj muaj qee qhov tsis zoo, xws li tus nqi siab, siab oxygen inhibition, thiab kev kho ceev ceev. Urethane acrylates yog tsim rau kev luam ntawv ntawm ntau yam substrates, xws li ntoo, tawv, thiab roj hmab, thiab rau cov ntawv thov uas yuav tsum tau ua kom muaj zog thiab puas.
Hauv kev xaus, oligomers yog qhov tseem ceeb rau kev tsim thiab kev ua haujlwm ntawm UV curable inks, thiab lawv tuaj yeem muab faib ua peb lub ntsiab lus, xws li epoxy acrylates, polyester acrylates, thiab urethane acrylates. Txhua chav kawm muaj nws qhov zoo thiab qhov tsis zoo, nyob ntawm daim ntawv thov thiab substrate. Txoj kev loj hlob ntawm oligomers thiab UV number case yog ib qho txheej txheem tsis tu ncua, thiab cov hom tshiab ntawm oligomers thiab kho txoj kev raug tshawb nrhiav kom tau raws li qhov xav tau ntawm kev lag luam number case.
