Te Take Me Manaaki Ki te Inka Takotoranga Ritenga mō te Kirihini
Me pēhea te porowaihinga kōpua, te hanganga mātā, me te rahi o te mata e here ana i te mahi ake o ngā inka noa?
Kei te uaua te hanganga o te peneiti tarau ki te urupare ki ngā inika mātai aunoa e mahi ana. He maha ngā momo porosity e rere ana i roto i te matēria, mai i ngā mata kiri kraft tōpito ki ngā takotoranga tarau e kurakura ana i ngā mea katoa. Ko tēnei e hāpai ana i ngā raru maha mō te whai ake o te inika i te tikangia, nā te mea ko te peneiti tarau he mea hanga i ngā waipiro e kore nei e āta wātea. E noho ana ngā wāhi wātea i waenganui i ngā taura cellulose e hāpai ana i ngā tikanga kapukapu tino rerekē ina tapaia ana. Ka uaua ake anō ngā mea ina uru atu ngā rongoā raimahi, nā te mea e hāpai ana ratou i ngā wāhi e toro ana i ngā tauira inika tūmatanui. Ka aha ka whai ake? Ka rere te whai ake o te inika ki ngā wāhi katoa, ā, ka noho ngā pigment i te kore-tikangia, ka uaua ai te prosihia tapa. Kāore ngā inika mātai aunoa e ū ana ki ngā tikanga tino hāngai e uru mai ana i te wā kotahi, nō reira kei te mātau ngā kaitapa i ngā panonitanga whai ake e noho ana, ā, kei te maroke anō te inika anō i te tere rawa i te paparorohiko.
Ngā putanga whai pūnga: te piki ahu kapi, te takotoranga kino, te wehe, me te tae heke taraweti ki ngā papanga kraft me ngā papanga whakamahia anō
Ko ngā raru motuhake ki ngā papanga rerekē e āraingia ana ki ngā raru tā mōhiotia ka taea te ine i te mea pea. Hei tauira, ko te pepa karaipē a kiriata hoki, e matotoru ana i te 60% o ngā muka kaihoko. Ina whakakīia e ēnei matūtini te inika anuanu, ka hua mai te ‘dot gain’ e piki ake ana i te tikanga whakaaetia e te ahumāra, arā ko te wāhi pakanga i waenganui i te 15% ki te 22%. Ka kitea hoki te whai mōhio inika e kore ai e taea te kī tonu i ngā wāhi iti, ngā wāhi porohita kei runga i ngā mata muka, ka hua ai ngā wāhi takotoranga takitahi. Ko tētahi atu raru nō ngā toihana maroke tere, ka hua mai te ‘set off’, arā ko te inika mākū e neke ana i tētahi pepa ki tētahi kaitekau. Ka uaua ake te whakauru tae ki ngā matūtini kiriata nā te kimi hipi noa atu me ngā parakirihou iti, ka huri te ara e uru ana te mata ki te āhuatanga kimikimi, ka huringa tae. Kua kite ētahi kaihanga i te pikinga o ō rātou rejeta tūranga e te 40% ina tāia ngā papanga kiriata i te ingoa o te papanga oronga mōhio, ina kāore rātou i whakarerekē i ō rātou tau inika.
Ngā Tira Rerekē Matua i te Whakaritenga Inki Āhuatanga
Te whanui o te rereketanga me te tautuhi o ngā tohutō mō te tuku me te huinga pai rawa atu ki te pepa kātene iti noa te kaha o te mata
He nui te take o te tika o te rerehua me te whakapainga i ngā kīato kī, ina eke ana ki te tuku i te tinta kia ū ana ki ēnei paparanga poro, papanui iti te hiko ake. Āwhina ngā kaiwhakarerekē i te rerehua kia āhua anō te rere o te tinta kia tukuna ai mā te papa ki te papanga kaua ko ngā raru pērā i te putanga o ngā pūkoro, i ngā raru rere. Ina heke te uira, ka wātea ake te tinta ki roto ki ngā whatu o te paparoi. Engari he uaua - me tātai tika ngā kīato kī kia mau tonu te kītonu me te takotoranga tika mā runga i ngā tāpihi. Mō te karahe whakamahia pea, e hurihuri ana te poro, me tino tika te uira kia pai ai. Ka āwhina ia ki te hanga i ngā ahua mārie ake, me te heke i ngā mōrearea o te takotoranga o ngā pepa tāpihi. Me kaua hoki te wareware i ngā tau: e ai ki ngā ripooti hōhonu mai i te Rōpū Hangarongo Tārai, ka mātau te rerehua kino ki te 25% atu ake o te paru i ngā mahi tā paparoi.
Kōwhiringa mātai (acrylic, PVA, nitrocellulose) hei whakapainga i te pākiuru me te kounga o te film ki ngā mata ohou
Ko te kimikimi mō ngā kaihuinga he wāhi matua nui ki te whiwhi pāpaku pai me te hanga i ngā kiri tino kaha ki te mata pēka, parahiko o te pepa kātene. Ka tū ake ngā parahi acarikaikia nā reira e āki ai i te maroke me te pakari ki te waimā, nō reira ko te kōwhiringa pai pea ina hiahiatia e ngā pouaka kia taea ai ngā huringa huapae i te wā o te puipui, rānei o te hokohoko. Mō ngā takotoranga roto o te taputapu, kei hea kāore ngā mea i te pēka pēka, ka mahi pai te parahi acetate polyvinyl (PVA) nā reira he kōwhiringa iti ake engari e taea ana anō. Ka maroke tere te nitrocellulose engari ka ngaro haere te maroke i te wā, nō reira ehara i te mea pai tonu mō ngā whakamahinga roa-roa. Ko te tiki i te taurite tika i waenganui i te maroke o te kaihuinga me te piko o te pepa kātene anō hei aukati i ngā arawhenua hara e mārama mai ana ina hōhonuhia, rānei ka nekehia ngā pouaka. Kua kitea e ngā tāwhaihua tākarotia tā karaihe acarikaikia e pā ana ki ngā mata kurakura i te 90% tūponotanga, tino pai ake i ngā momo papai e tino eke ana ki te 70%. Engari ko te mea nui rawa atu ko te pānga o ēnei kaihuinga ki te hanga i ngā kiri maeneene, ū āraitia e kore e wehe anō i ngā wā e noho ana ki ngā tikanga noho tāiao.
Te Whakanui i te Tūhuratanga me te Mahi Āhuatanga: Te Utu, Te Arataki, me ngā Āhuatanga Whakaputa
Ngā arataki mō te kai-kore e taea ana te nekeneke, te manawaroa ki te aho rangi, me te manawaroa ki te whero – pērā i te pānga o te whakamahi whakamutunga ki ngā whakataunga matū momo tinta
Ko ngā mea e mōhiotia ana i te mutunga o te rārangi hōtaka e whakarātia ana e ngā inka tūhono noa i te kore e taea te whakahaere. Mō ngā pakete e whai pānga ana ki te kai, me āki ai ngā kamupene i ngā ture ngawari mai i te FDA 21 CFR, i ngā paerewa EU 10/2011 rānei e pā ana ki te nui o ngā mea e taea ana te rere atu i te inka. Ko te tikanga, me whakamahi i ētahi kaiwhangai motuhake e wāwāhi ana i te rere o ngā kimikime tūkino. Me kaua hoki te utu e wareware. I tā te Rōpū Ponemon i 2023, ko ngā hua e kore nei e whakaaetia ka hua ai ngā tono whakahoki e mau ana i te $740,000 ia wa. Mō ērā whakangahau nui ki waho e kitea ana i ngā wāhi katoa, me hiahia ngā kaiwhakaputa e kore e māmātia pea i te rā i te wā roa. Me whakarite kia tata ki te ASTM 5 ki ngā paerewa ahumahi. Anō hoki ngā taputapu pakete e neke haere ana i ngā wharepukapuka, i ngā waka tuku rānei. Me hiahia i ngā kiri e taea ai te marere, te marere hoki i te wā o te kawe. Ko ēnei whāinga a-taiao katoa e whakatau ana i te aha e whakaurua ana ki te hanga i ēnei inka motuhake.
- Tikanga kai : Ngā kaiwhakakapi acrylate iti ake ngā kōwhiringa e pā ana ki ngā phthalate
- Te Whara UV : Ngā pigment inorganic noa atu, i te ahua tino pai rānei ngā pigment organic e tūhono ana i ngā kōwhiringa iti ake te āhua
- Tiaki i te mātukutuku : Ngā punaha harinui kua whakarerekia nitrocellulose, i ngā harinui hoki e kākahu ana i te pono o te mata
Kāore anō te kite i te horopaki whakamahi mutunga ka kino ai te kounga tuhinga—ka pakanga hoki i ngā tohu ki ngā whakawainga here, ngā wero hou i te tīwae tukutuku, me ngā herenga ingoa. Ko te whakaritenga tika mō ngā tinta e hāngai ana ki te papamuri, ki te whakamahinga hoki kaore i te kōwhiringa, engari he takotoranga matua mō te whakaputa pakipaki tika, ā-mōrahi hoki.
FAQ
He aha te take e uaua ai te carton mō ngā tinta tuhinga āhuarangi?
E whai pūtake pīroiroi hoki te carton me te hanganga paraihe e pā ana ki te kauwhau tika i te tinta. Ka hua ai tētahi kohikohi momo paitini, me ngā raru hoki i te toronga o te tinta.
He aha ngā raru matua e pā ana ki ngā tinta tikanga ki te carton?
Kāore ngā inika tīmata e āhua ana ki ngā raruraru pēnei i te whānuitanga o ngā tohu, kāore he pai te takotoranga o te inika, te wehe haere, me te tae e kore e rite ina whakamahia ki ngā papakupenga kraft me ngā papakupenga kirihou.
Me pēhea te whakarerekē i te inika mātai āwhāwhā hei hua pai ake mō te papakupenga?
Might include adjusting rheology and pigment loads, selecting appropriate binders, and ensuring ink formulations meet specific end-use demands like food safety and UV resistance.
