Inkawa Whakawhanakea Taurite mō Nga Hanga Rangirua

Ko te Flexo solvent he mea nui kē ki ngā tae whakamātau flexographic, e whai wāhi ana i te whakatau i ngā āhuatanga me ngā mahi o te ink i roto i te mīhini. E toru ngā mahi o ngā solvent i roto i ngā tae whakamātau flexographic, ka hiahia hei hanga i ngā pūmau pai. Tuatahitia, ko ngā solvent Flexo he kaiwhakawā mo ngā piki, ngā binders, me ngā taumaha kē o te ink. He mea rere i aua raraunga, he whakapakari i tētahi huaki pai ink, ka taea te whakamahi i runga i te papa. Ki te whakatakoto pai i ngā raraunga o te ink, ka whiwhi te kaiwhakawā i te whanaketanga rangi pai me te whakarite pai. Ka whakaaro anō te kaiwhakawā i te whakapakari piki, inā e rerekē ana ngā pūkenga o ngā solvent kē ki te whakamahana me te whakapakari i ngā piki, e āheinga ana i te whanaketanga rangi me te ata pai o ngā kōrero whakamātau. Tuatoru, kei a ngā solvent Flexo te whakahaere i te viscosity o te ink. Ko te viscosity he mea nui ki te mīhini flexographic, inā e whakatau ana i te wawe i reira ai te ink me te whakamutu mai i te papa mīhini ki te papa. Kei te whiriwhiria ngā solvent me te whakapakari pai ki te whakatika i te viscosity pai mō ia taumata mīhini. Ko te solvent iti viscosity ka whakamahia i te ink hei rere rawa, e pai ana mo te mīhini atawhai rānei, arā, mo te mīhini i runga i ngā papa poripori, ahakoa ko te solvent viscosity nui ka whai wāhi hei whakamahi i runga i ngā papa kore-poripori rānei, hei whakatika i ngā tahuhu ink pai. Ko te waenganui o te whakarite i te tae o ngā tae whakamātau flexographic ka whakaae hoki i ngā solvent. Ko ngā solvent Flexo me te kotahi boil point iti ka haere noa, ka whakaaetia te tae ki te drie noa i runga i te papa. Ko tēnei mahi-drie weweke e hiahia ana ki ngā taumata mīhini kē, inā ka whakamahia te wā kaiwhakatū pai, ka heke te take o te smudging rānei, te offsetting. Ahakoa, ka whakaaro anō te waenganui o te drying ki te whakatakoto pai i te whakapae tae me te whakapakari rangi. Ki te haere noa i te solvent, ka puta ngā take pērā i te kino whakapae ink ki roto i te papa rānei, te drying rahi, ka whakatupu i ngā momo kē i ngā kōrero whakamātau. No reira hoki, kei te whakaaetanga o ngā solvent Flexo ki te whakarite i te tae i runga i ngā papa kē. Ka whakanuitia ētahi solvent ki te mahi pai i runga i ētahi whenua, ka whakapai i te whakapae tae me te whakatika pai i aua papa. Hei tauira, ko ngā solvent ka taea te wehe i te papa plastic, ka whakapai i te hononga tae-papa. Ahakoa, ko te whakamahi i ngā solvent Flexo tawhito, ā, āhei ana ki ngā huinga VOC (Volatile Organic Compounds) kē, ka whakatōpu i ngā take tuawhenua me te hauora. Nō reira, kei te whakatōhea te huarahi whakamua ki te hanga i ngā solvent Flexo pai tonu, ā, he iti VOC rānei, he bio-based solvents, ka taea te whakamahi i te tae pai tonu, ka heke i tana whakaaro tuawhenua.
