Hiki ke hoʻopili koke ʻia nā uhi UV wai wai a hoʻōla ʻia ma lalo o ka hana a nā photoinitiators a me nā kukui ultraviolet. ʻO ka pōmaikaʻi nui loa o nā resins e pili ana i ka wai, ʻo ia ka viscosity hiki ke hoʻomalu, maʻemaʻe, pili kaiapuni, mālama i ka ikehu a maikaʻi, a hiki ke hoʻolālā ʻia ke ʻano kemika o ka prepolymer e like me nā pono maoli. Eia nō naʻe, he mau hemahema kēia ʻōnaehana, e like me ke kūpaʻa lōʻihi o ka ʻōnaehana hoʻoheheʻe wai uhi pono e hoʻomaikaʻi ʻia, a pono e hoʻomaikaʻi ʻia ka absorption wai o ke kiʻi hoʻōla. Ua hōʻike kekahi poʻe akamai e ulu ana ka ʻenehana hoʻōla māmā wai i ka wā e hiki mai ana i kēia mau ʻaoʻao.
(1) Hoʻomākaukau i nā oligomers hou: me ka haʻahaʻa haʻahaʻa, ka hana kiʻekiʻe, ka ʻike paʻa kiʻekiʻe, ka multifunctionality a me ka hyperbranching.
(2) E hoʻomohala i nā mea hoʻoheheʻe hou: me nā mea hoʻoheheʻe acrylate hou, me ke kiʻekiʻe o ka hoʻololi ʻana, kiʻekiʻe reactivity a me ka haʻahaʻa haʻahaʻa.
(3) Ka noiʻi ʻana i nā ʻōnaehana hoʻōla hou: I mea e lanakila ai i nā hemahema o ka hoʻōla piha ʻole ʻana i kekahi manawa ma muli o ke komo ʻana o nā kukui UV, ua hoʻohana ʻia nā ʻōnaehana hoʻōla ʻelua, e like me ka free radical photocuring/cationic photocuring, free radical photocuring, thermal curing, free radical. photocuring, a me free radical photocuring. Ma muli o ka photocuring / anaerobic curing, free radical photocuring / moisture curing, free radical photocuring / redox curing, etc., hiki ke hoʻokō piha ʻia ka hopena synergistic o nā mea ʻelua, e hāpai ana i ka hoʻomohala hou ʻana o ke kahua noi o nā mea wai photocurable.
