Ngā Tinta Piriti Paraihe Wai Mātai Kaihautū mō te Tauparotanga Tūhonu

Ko ngā tinta mātātoko flexographic i hangaia kia mahi i ngā tikanga motuhake o te tikanga mātātoko flexographic, e mōhiotia ana mō tana whakamahinga i ngā paparorohiko maroke me tētahi punaha tinta rerehua. Ko te āhua ki roto i ngā waehe e whakaatu ana i te herenga o muri i tētahi huinga angitu. Ko te pigment te kawe i te tae, engari ko tana whakawhitinga ki te kauta me te kawe kua whakatau ai i ngā āhuatanga o te papa tinta mutunga. Hei tauira, ko ngā pigment parakore e whakamahia ana i ngā tinta mārui ka whiriwhiria mō ō rātou āhua parakore, tonu, me te arataki. Ko ngā pigment anorganic mō ngā tae tukutuku ka whiriwhiria mō ō rātou mārohirohi, kaha tae, me te pūmau. Ko te punaha kauta te tuanui o te tinta. I ngā tinta huinga wai, he emulsion, nō reira he horapa o ngā resin acrylic, polyurethane, maleated rosin rānei. I ngā tinta huinga parahi, he nitrocellulose, polyamide, polyurethane rānei ngā resin e hua ana. I ngā tinta UV, ko te kauta he whenua (hei tauira, epoxy acrylate mō te pūkaha, urethane acrylate mō te maroke) me ngā monomer (diluents whakarewa) e hono ana i te wā o te whakapai. Ko te tuatoru matua o te kawe he kawe i te pigment me te kauta ki te paparanga. I ngā tinta huinga wai me ngā tinta huinga parahi, ka mawhara te kawe. I ngā tinta UV, ko ngā diluents whakarewa ka waiho hei wāhanga o te papa whakapai mutunga. Ko ngā taonga tapa he mea ngaro e whakatika ana i te noho o te tinta. Ko ngā kaiwhakamarie ka whakapai ake i te whakamarie ake ki te paparanga. Ko ngā kaiwhakamarie ka whakarereke i te hanga pahu. Ko ngā taonga wax ka whakapai ake i te manawa. Ko ngā kaiwhakawhiti ka whakaiti i te urupare. Ko te whakamahi mutunga e whakatau ana i te huinga. E hiahiatia ana te manawa ki te alkali mō tētahi kapi sap. E hiahiatia ana te manawa ki ngā hinu me ngā parakore mō tētahi kapi piharau. E hiahiatia ana te manawa ki te mārama kaha mō tētahi pouaka takotoranga. Ka tōaitia ia herekenga i te kaihuinga kia whiriwhiri i te takotoranga tika o ngā rawa. Ki te kōrero mō ō hiahia tinta flexographic ā-whatu, me te tiki i ngā tohutohu ā-tiriti e hāngai ana ki āu paparanga, taputapu mātātoko, me ngā herekenga mahi, tēnā whakapā atu ki ā mātou tohunga hangarau. Kei te tūpono mātou ki te tuku i ngā korero takitahi me te āwhina e hiahiatia ana mō āu kaupapa.
