Oligomers Ogwiritsidwa Ntchito mu Inki ya UV

Ma Oligomers ndi mamolekyu omwe amakhala ndi mayunitsi angapo obwerezabwereza, ndipo ndi zigawo zazikulu za inki yochiritsika ya UV. Ma inki ochiritsika a UV ndi inki yomwe imatha kuumitsidwa ndikuchiritsidwa nthawi yomweyo chifukwa cha kuwala kwa ultraviolet (UV), zomwe zimapangitsa kuti ikhale yoyenera kusindikiza mwachangu komanso njira zophikira. Ma Oligomers amachita gawo lofunikira pakuzindikira mawonekedwe ndi magwiridwe antchito a inki yochiritsika ya UV, monga kukhuthala, kumamatira, kusinthasintha, kulimba, ndi mtundu.

Pali magulu atatu akuluakulu a oligomers ochiritsika ndi UV, omwe ndi epoxy acrylates, polyester acrylates, ndi urethane acrylates. Gulu lililonse lili ndi makhalidwe ake ndi ntchito zake, kutengera mtundu wa substrate, njira yochiritsira, ndi mtundu womwe mukufuna wa chinthu chomaliza.

Ma epoxy acrylates ndi ma oligomer omwe ali ndi magulu a epoxy kumbuyo kwawo, ndi magulu a acrylate kumapeto kwawo. Amadziwika ndi reactivity yawo yambiri, kukhuthala kochepa, komanso kukana mankhwala bwino. Komabe, alinso ndi zovuta zina, monga kusinthasintha kosakwanira, kusagwirizana kochepa, komanso chizolowezi chachikasu. Ma epoxy acrylates ndi oyenera kusindikizidwa pa zinthu zolimba, monga chitsulo, galasi, ndi pulasitiki, komanso kugwiritsa ntchito zomwe zimafuna kuwala kwambiri komanso kuuma.

Ma polyester acrylates ndi ma oligomer omwe ali ndi magulu a polyester kumbuyo kwawo, ndi magulu a acrylate kumapeto kwawo. Amadziwika ndi reactivity yawo yocheperako, kuchepa kochepa, komanso kusinthasintha kwabwino. Komabe, alinso ndi zovuta zina, monga kukhuthala kwakukulu, kukana mankhwala pang'ono, komanso kutulutsa fungo. Ma polyester acrylates ndi oyenera kusindikizidwa pa zinthu zosinthasintha, monga pepala, filimu, ndi nsalu, komanso kugwiritsa ntchito zomwe zimafuna kumamatira bwino komanso kusinthasintha.

Ma acrylate a urethane ndi ma oligomer omwe ali ndi magulu a urethane kumbuyo kwawo, ndi magulu a acrylate kumapeto kwawo. Amadziwika ndi reactivity yawo yochepa, kukhuthala kwakukulu, komanso kusinthasintha kwabwino. Komabe, alinso ndi zovuta zina, monga mtengo wokwera, kuletsa mpweya wambiri, komanso kuthamanga kochepa kochira. Ma acrylate a urethane ndi oyenera kusindikizidwa pazinthu zosiyanasiyana, monga matabwa, chikopa, ndi rabala, komanso kugwiritsa ntchito zomwe zimafuna kulimba kwambiri komanso kukana kukwawa.

Pomaliza, ma oligomer ndi ofunikira popanga ndi kugwiritsa ntchito ma inki ochiritsika a UV, ndipo amatha kugawidwa m'magulu atatu akuluakulu, omwe ndi epoxy acrylates, polyester acrylates, ndi urethane acrylates. Gulu lililonse lili ndi zabwino ndi zoyipa zake, kutengera momwe amagwiritsidwira ntchito komanso gawo lapansi. Kupanga ma oligomer ndi inki ya UV ndi njira yopitilira, ndipo mitundu yatsopano ya ma oligomer ndi njira zochiritsira zikufufuzidwa kuti zikwaniritse zosowa zomwe zikuwonjezeka za makampani a inki.
