Oligomers Omwe Amagwiritsidwa Ntchito Pamafakitale a Ink a UV

Oligomers ndi mamolekyu omwe amakhala ndi mayunitsi angapo obwerezabwereza, ndipo ndiwo zigawo zikuluzikulu za inki zochiritsika ndi UV. Ma inki ochiritsika ndi ma inki omwe amatha kuwumitsidwa ndikuchiritsidwa nthawi yomweyo poyang'aniridwa ndi kuwala kwa ultraviolet (UV), zomwe zimawapangitsa kukhala abwino posindikiza komanso zokutira mwachangu. Oligomers amagwira ntchito yofunika kwambiri pozindikira momwe ma inki ochiritsira a UV amagwirira ntchito, monga ma viscosity, adhesion, kusinthasintha, kulimba, ndi mtundu.

Pali magulu atatu akuluakulu a oligomers ochiritsidwa ndi UV, omwe ndi epoxy acrylates, polyester acrylates, ndi urethane acrylates. Kalasi iliyonse ili ndi mawonekedwe ake ndi ntchito zake, kutengera mtundu wa gawo lapansi, njira yochiritsira, komanso mtundu womwe umafunidwa wa mankhwala omaliza.

Ma epoxy acrylates ndi oligomers omwe ali ndi magulu a epoxy pamsana wawo, ndi magulu a acrylate kumapeto kwawo. Amadziwika chifukwa chakuchita bwino kwambiri, kutsika kwakanthawi kochepa, komanso kukana mankhwala abwino. Komabe, amakhalanso ndi zovuta zina, monga kusasinthasintha, kutsika kumamatira, ndi chizolowezi chachikasu. Ma epoxy acrylates ndi oyenera kusindikiza pazigawo zolimba, monga zitsulo, galasi, ndi pulasitiki, komanso ntchito zomwe zimafuna kuwala kwakukulu ndi kuuma.

Ma polyester acrylates ndi oligomers omwe ali ndi magulu a polyester pamsana wawo, ndi magulu a acrylate kumapeto kwawo. Amadziwika chifukwa chakuchitapo kanthu pang'ono, kuchepa pang'ono, komanso kusinthasintha kwabwino. Komabe, alinso ndi zovuta zina, monga kukhuthala kwakukulu, kutsika kwamphamvu kwamankhwala, komanso kutulutsa fungo. Ma polyester acrylates ndi oyenera kusindikizidwa pazigawo zosinthika, monga mapepala, filimu, ndi nsalu, komanso ntchito zomwe zimafuna kumamatira bwino komanso kukhazikika.

Urethane acrylates ndi oligomers omwe ali ndi magulu a urethane kumbuyo kwawo, ndi magulu a acrylate kumapeto kwawo. Iwo amadziwika chifukwa chochepa reactivity, mkulu mamasukidwe akayendedwe, ndi kusinthasintha kwambiri. Komabe, amakhalanso ndi zovuta zina, monga kukwera mtengo, kuletsa kwa okosijeni wambiri, komanso kuthamanga kwa machiritso otsika. Urethane acrylates ndi oyenera kusindikiza pazigawo zosiyanasiyana, monga nkhuni, zikopa, mphira, komanso ntchito zomwe zimafuna kulimba kwambiri komanso kukana kwa abrasion.

Pomaliza, ma oligomers ndi ofunikira pakupanga ndi kuchita kwa inki zochizika ndi UV, ndipo amatha kugawidwa m'magulu atatu akulu, omwe ndi epoxy acrylates, polyester acrylates, ndi urethane acrylates. Kalasi iliyonse ili ndi ubwino wake ndi zovuta zake, malingana ndi ntchito ndi gawo lapansi. Kupanga oligomers ndi inki ya UV ndi njira yopitilira, ndipo mitundu yatsopano ya oligomers ndi njira zochiritsira zikufufuzidwa kuti zikwaniritse zomwe zikuchulukirachulukira zamakampani a inki.
