Ngā Tinta Piriti Paraihe Wai Mātai Kaihautū mō te Tauparotanga Tūhonu

Ko ngā tinta mātai papahiko he pūnaha rauemi horapa e matua herekore ana ki te angitu o te tikanga mātai papahiko, e mōhiotia ana mō tōna āhua me tōna kaha ki te takirua i runga i ngā mata takotoria me ngā mata maroke. Ko ngā wāhanga matua ko ngā kiriata (ngā tuarangi, ngā momo rerehua rānei), ngā kaiwhakawhitinga (ngā reti e hangaia ana ai te ripa), ngā kaihīkoi (wai, parahi, i te monomera whakaputa mō te UV), me tētahi rōpū kaiwhakapai ake i te mahi. He matua herekore te kōwhiringa i te reti kaiwhakawhitinga nā te mea ka whakatau ia i ngā āhuatanga pānga, mārama, me te manawaroa. Ko ngā reti acrylic he noho tūmatanui i ngā pūnaha huinga wai mō te pepa me te poro, ā, ko ngā reti polyurethane kei te tōaitanga i ngā pūnaha huinga parahi mō te takirua ripa nā te kaha ake ki te āhua me te manawaroa kimikimi. I roto i te UV flexo, ko ngā epoxy acrylates, ngā urethane acrylates rānei e tuku ana i te whatitoka huinga mō te kaha pakari rawa atu. Ko te tikanga takirua anō e tāpaetia ana ngā here ki te arataki o te tinta. I te wā o te ine e te rōrangi anilox, me iti noa te uira o te tinta kia kī katoa ngā wā katoa engari me kaha tonu kia taea te wehe i te pāpā. I te wā e tukuna ana ki te papamuri, me whakahaere tika te kaha pānga me te kaha herehere o te tinta kia kaua ai e huaki ngā tohu iti, kaua hoki e hono hono ai i ngā tohu iti. Whakamutunga, e hiahiatia ana te kounga o te takirua ki te mata, ko te take ko te piko o te mata o te tinta ki te kaha mata o te mata. Ko te herenga tūmatanui i te takirua i ngā parahi kore-poro, pērā i te PET, OPP rānei, ko te herehere iti, e taea ana te whakatika mā te whakarongo i te mata (pērā, corona, ahi rānei) me te hanga tinta ki ngā kaihīkoi tika me ngā kaiwhakapai herehere. Whakaarohia te whakamahi i te takirua ripa mō ngā kete tino maroke mō ngā kai tio. Me nui ake te āhua o te ripa tinta kia kaua ai e popokina i ngā wāhi makariri, ina nui pea ki te -30°C, me kaha hoki ki te manawaroa i te whakapapa kia mau tonu ai te ahua ake i te tīmatanga makariri, tae atu ki te taraiwa me te penapena. Mērā ka porerua, ka taea te porerua o te ahua, ka hinga ai te kitea o te tohu. Ko tētahi atu āhuatanga ko te takirua i ngā kete maha-ripa mō te pūpahi, kimikimi rānei, me pā te tinta ki te papamuri PP e whatu ana engari me manawaroa hoki i te māmā o te UV roa me te tino whakapā ki te whakamahinga kino. Mō ēnei whakamahinga, ko ngā pūnaha tuarangi kaha-tino me te āhuatanga reti kaha he mea matua herekore. Ko te hiahia o te ahumāra ki te tika anō anō hoki e āki nei i te hanga tinta. Kei te whanaketia ngā tinta flexo huinga wai mō ngā whakamahinga pepa, poro rānei ki te piki ake i te ihirangi reti e tīkina ana mai i te taiao me te heke iho i ngā mea kino. Kei te piki ake te whakamahinga o te hangarau UV LED mō te whakaputa nā te iti ake i te whakamahi kaha, te kaha tīmata tūmatanui, me te roa ake o te rama ki te tāpiri atu ki ngā rama mercury arc tuku iho, me ngā tinta e hiahiatia ana kia hangaia me ngā kaiwhakaputa motuhake e āhua ana ki te roimata LED, heoi ko te 395 nm. Ko te whakahaere kounga i te hanga tinta flexo e whai mātai ana i ngā whakamātau paku, pērā i te kounga o te parai, te pūmahara uira, te kaha o te tae, me te kēmu hue. Ki te kōrero mō tō mata, tō whiriparamua, me ngā here whakamutunga, me te ako mō te āwhina a mātou i ngā ratonga tinta flexographic ā-tiriti e tuku ana i ngā hua tino kounga, tūmau mō tō whakangao, ka tono mātou kia whakapā atu koe ki ā mātou tohunga mō te āwhina whānui me ngā korero hua katoa.
