Whakamahinga Inka Ua Flexo mō te Tātuhi Matatū

Te whakarite i te miro UV flexo he mea whakamahara me te tatau nui, e hāngai ana ki te kawe mai i ngā pūtake katoa hei hanga i ngā miro e pai ana ki te whakahanga flexographic me te whakatika ultraviolet. Hei tiki i te wāhi matua o ngā āhuatanga o te miro, i runga i ia pūtake i te whakarite, ka noho nui te wā i whakaae ai i ngā āhuatanga o te miro, mai i te pai o te kiri ki te roa o te whakatika me te whakatika. He mea nui ngā pipihi i roto i te whakarite o te miro UV flexo. Ko ngā pipihi kei a rātou te kawe i te tae o te miro, ka whakaaetia i te hunga rerekē. He nui te uara o te tae, nā tērā ka whakaaturia he aha te mākū o te tae i whakaputa ai. He pipihi me te uara tuatahi ka kitea te tae whakahirahira, ā, i te wehenga o ngā kohinga miro. Ko te whakarite i ngā pipihi i runga i ngā take rerekē. Ko te wehenga o ngā kōwhiti me te āhua o ngā pipihi ka whakaheke i te tomo o te miro, i te āhuatanga kuhu me te taea i te whakahanga. Ko ngā monomera me ngā oligomera he pūtake matua mō te miro UV flexo. Ko ngā monomera he pūtake iti i te mīria ki te kawe i te whakatika me te whakaputanga i te wā o te whakatika UV. Nā te heinga o ngā oligomera ka tuku i te whiu me te āhuatanga film o te miro i whakatikatia. Ka whakaaetia te whakarite i ngā monomera me ngā oligomera i runga i ngā āhuatanga kāorekore o te miro i whakatikatia, mai i te kaha ki te wero me te whiu. Ka whakamahi ngā huinga rerekē hei hanga i ngā miro e pai ana ki ngā taunga rerekē me ngā whakamahi. Hei tauira, ko ngā miro mō te whakahanga i runga i ngā rau pakipaki ka hiahiatia he film motuhake, ahakoa ko ngā miro mō ngā raupapa ka hiahiatia he kaha me te whiu. Ko ngā photoinitiatora he pūtake nui i roto i te whakarite o te miro UV flexo, nā rātou te kawe i te whakatika. I te kitea i te marama UV, ka whakaaetia ngā photoinitiatora i te kōwhiri marama ka puta i te momo kawe, pērā i ngā kawe motuhake rānei. Ka kawe ngā kawe nei i ngā monomera me ngā oligomera, ka whakaputaina ki te whenua me te hanga i te whenua herehere. Ko te momo me te whatitiri o ngā photoinitiatora ka whakamahia he nui ki te whakarite i te wā o te whakatika me te pai o te miro. Ko te whatitiri nui o ngā photoinitiatora ka puta te whakatika haere, engari ka whakaaetia hoki i te ao o te miro me ētahi atu āhuatanga. Ka whakamahi ngā tāweka i te whakarite o te miro UV flexo hei whakatika i ngā āhuatanga rerekē. Ka whakamahi ngā surfactants hei whakautu i te tomo mata o te miro, hei tautoko i te pai o te whakapae me te whakapae pai ki te taunga. Ko tēnei ka tautokia te whakakore i ngā take, pērā i te mate o te miro. Ka whakamahi ngā whakakore i te whakatika i te tomo o te miro, ka pai ai hei whakahanga flexographic. Ko te whakaaetanga i te tomo he mea nui kia pai ai te kawe pai o te miro mai i te rau whakahanga ki te taunga. Ka whakamahi ngā defoamers hei whakakore i te whakatū pūrepo i te wā o te hanga miro me te whakahanga, nā te pūrepo ka whakawehewehea te pai o te whakahanga. Ka whakaaro anō i te whakarite o te miro UV flexo i runga i ngā āhuatanga taiao me te haumaru. I ngā tau whakarewa, ka whai take te hokinga whakamua ki te hanga i ngā miro motuhake me te iti i ngā taiao (VOC) e tukuna ana. Nā tērā ka whakamahi i ngā pūtake rerekē me te whakatika i ngā whakarite hei tautohu i ngā ture taiao nui. Ki te kotahi, ko te whakarite i te miro UV flexo he tatau nui, he mea whakamahara. Me te mōhio pai ki ngā āhuatanga me te mīhini o ngā pūtake, o te kawa o te whakahanga, me ngā take whakamutunga o ngā mahi whakahanga. Kei te whai wāhi tonu ngā rangahau me te whakamahere hei whakapai i ngā whakarite miro, hei tautoko i te pai, te tiaki taiao, me te whakarite motuhake mō ngā hiahia whakarerea a te whenua whakahanga.
