Ngā Tinta Piriti Paraihe Wai Mātai Kaihautū mō te Tauparotanga Tūhonu

Ko ngā tinta mātai ā-tauira he pūnaha whanake, kua rite ngā āhuatanga mutunga anake i muri i te wā o te horapa rānei, rānei te houkui. Ko te tikanga horapa te mea matua e wehe ana i waenganui i ngā momo tinta. Ko ngā tinta huinga wai ka horapa anō hau ki te paripari, i te tīmata anō hau, ā, ka āwhina mai ngā taputapu horapa hau mahana ki te pehi. Ka pakaru te tere horapa e te painga o te wera o te hau, te tere, te huha, me te porowhiti o te papamuri. Mā te horapa kore pea ka puta ai te here (ka herea ngā pepa ki te puopuo) i te tāpae, i te tāpae rānei (ka neke te tinta ki te tuarā o te pepa panoni). Ko ngā tinta huinga parahi ano ka horapa anō hau, engari ko te nuinga o te wā he tere ake tēnei, me ngā pūnaha whakauru anō rānei, whakaputangia rānei i ngā parahi kia āki ai i ngā putanga VOC, kia noho haumaru ai i te wāhi mahi. Engari, ko ngā tinta UV flexo, ehara i te horapa anō hau engari mā te photopolymerization. Ina tū ake ki te āhua UV, ka wehe ngā kaiwhakahohe photo ki ngā tuarangi noa, ā, ka tīmata tētahi arotake karuwha e hono ana i ngā oligomer me ngā monomer ki tētahi whatitiri taumata, whatianga inerti i roto i ngā miriona sekene. Mā tēnei houkui tata ki te takirua ka taea tētahi mahi tonu i muri mai, pērā i te tahurangi, i te totohu rānei, ā, ka hua mai he mata kua pai ake te manawaroa ki ngā mea kikokiko, ki te parurenga hoki. He wāhi matua mō ngā tinta UV flexo kei ngā tapanga kiri whakamaroke. Ka whakaputaina te tapanga i runga i tētahi kōpae, kātahi ka tukuna atu ki tētahi tūrama wera, ka paku ake te kiri ki ngā āhuatanga o te kōpae. Me āki ai te tinta i tēnei wera kaha, tere kia kaua ai e mārearea, e popoka rānei, e ngaro rānei te here. Nō reira, ko ngā tinta kua houkuihia e te āhua, nō reira hoki tā rātou ake āhuatanga thermoset, he pai rawa atu mō tēnei tikanga uaua. He mea aronga anō ko te ū ōrite o te tinta ki ngā kapi, ki ngā herehere hoki. I ngā pūtea maroke, ko te taura tāpihitia e whai ake ana te tahurangi ki tētahi atu kiri mā te whakamahinga i ngā herehere. Me kaua te tinta i ngā wāhanga e neke ana ki te rerekētanga herehere ka paingia ai te tahurangi (te herenga kore). E hiahiatia ana he hanganga tino tata kia ū ai te whatitiri tinta kua houkuihia ki ngā herehere tahurangi e huinga parahi ana, e huinga wai ana. Mō ngā tapanga, ka taea te whakaputa i tētahi kapua, i tētahi varnish rānei ki runga i te tinta kia hua ai te āhua marino, kia tuku ai i ētahi āhuatanga takotoranga motuhake; nō reira me āki ai te tinta i te herenga tino pai ki tēnei varnish tārai. Ko te horopaki here herea o te ao anō hoki he kaiarahi matua. Ko ngā ture pērā i REACH ki Ūropi, Prop 65 ki Kaliforni, me ētahi atu ture pā ki ngā kai o te ao e here ana i ngā mea e whakaaetia ana kia whakamahia ki ngā hanganga tinta. E hiahiatia ana tētahi pūkenga here herea kaha, tētahi mahi tahi tata hoki ki ngā kaihautū matū kia ū ai ki ngā here o te ao. Ki te mōhio ake mō ō maatau ratonga tinta flexographic ā-whakauru, ā-haepapa, me pēhea e taea ai te whakauru ki ōu tikanga tāpihi, whakarerekē hoki, tēnā whakapā mai ki tā maatau timatanga mō tētahi kōrero ngāhere, ā, tirohanga mō te whakamahinga.
