He aha ngā painga e āwhina ai te tinta intaglio wai mā te whakaprint i te papanga?

Ngā Painga Aronui me ngā Tikanga Whakahaere o te Tinta Whakaprinta Intaglio Wai mō te Pāpaku

Te Heke i ngā Whakapunga VOC me te Tinta Wai

Ko ngā inu tā mātāpuna heke i ngā kohinga takotoranga takitahi (VOCs) e 95% ina whakaritea ki ngā kōwhiringa kua whakamahia mua, e whakatika ana i tētahi o ngā raru huri taiao nui rawa e pā ana ki ngā kaihanga pāpaku huaora i ēnei rā. Ko te huri mai i ngā kaiwhakangao takitahi ki ngā kaiwhakauru haumaru ake ka whakamahia ngā tauira pāpaku wai heke i te koreake te kohinga VOC, i te nuinga o te wā heke iho i te 25 grama ia litra, nō reira ka tino whakauru hoki ki ngā here o ECOCERT EU mō ngā hua hauhake. Kātahi anō ka pai ake te taiao, engari ka tiaki hoki i te hauora o ngā kaimahi. Ko ngā whare wā manufacturing e whakamahi nei i ēnei inu hou e heke i te 1.2 tōne mita o te kirikiri whakaputangia ia tau, e ai ki te rangahau mai i te Rōpū Ponemon i te tau 2023. Ko te rite tonu ki te kohinga whakakaha o te 260 waka tūmatanui kua tangohia i te ara.

Ngā Painga Whakamau Taiao ki ngā Whakamahinga Pāpaku Huaora

Ko te mātātika o ngā inki mā runga wai e āwhina ana i te whakarewa i ngā kiriata hua pīroiroi ki te tikanga kaipuke kua whakakaha. Kātahi ka taea e tēnei te whakapōuri i ngā waihanga PET me te polypropylene mai i ngā kaipuru, ko te nuinga o ngā kamupene hua kaihoko e hiahia ana kia eke atu ki ngā whāinga o te tau 2030 mō te Ōkiko o te ao. E ai ki tētahi rangahau i tāwhāhia i te tau ki muri e arotake ana i ngā tekau mā whā ngā kamupene taputapu huihuinga ki te ao, ko te neke atu ki te taupānga intaglio iti rawa i te wai i whakaiti i te whakapai wai i te tata ki te toru hauwhā me te whakaora i te tuatoru o te hiko i whakamahia ai i ngā tikanga tūmatanui ki te whakarite inki UV. Mō te taputapu kai, ko tēnei he mea nui rawa, i te mea kāore ngā whiringa wai i te whai ngā mea hāpōtiki pērā i ngā phthalates, ngā metā rākei e āwhina ana kia kore pea i te ture whakaaetanga o te FDA i te wāhi 175.300 o te taitara 21.

Te Whakaaetanga ki ngā Ture Mō Te Taiao o te Ao me ngā Whakaritenga Ahumoni

Ko ngā inki intaglio huinga wai e whakatutuki ana i ngā ture o te ao eke nei. Ka taea e koe te tiki i ngā whakaritenga CARB ATCM o California me te ture GB 38507-2021 o Haina hei tauira. E hiahiatia ana e ētahi katoa ngā rerekētanga o te wa irirangi heke iho i te 100 karamu ia litir, ā, kua oti tā mātou huinga wai i te nuinga o te wā. Ina manawapōhiri ngā kamupene ki te Rārangi Kupono Kua Tāukumea e EPIA (European Printing Ink Association), ka whakaaetia ake rātou ki ngā ture o ngā 43 whenua rerekē. Ko tēnei momo whakaaetanga e hoatu ana i te whirinakitanga ki ngā pakihi ina mahi rātou ki waho o te whenua. I kitea e ētahi kaiwhakamahi tuatahi kua roa ake te whakaaetia i te 27% pakanga pakanga i runga i te tikanga. Anō hoki, ka noho ake rātou i te 19% iti ake ngā raihana e pā ana ki ngā take ture i ngā tāngata e whakamahi ana tonu i ngā inki pātai hauauru. He mārama te nuinga o ngā kaihanga e huri ana i ēnei rā.

Mō ngā inenga tata ki te whakaaetanga ture, tirohia ngā taumata VOC tuku comparea ki te Pūrongo Pakihi Kaitiaki 2024.

Kounga Whakapāpaku me te Whakapiri Pai ki runga i ngā Raro Plastik

Putanga Whakapāpaku Kaiwhakamahi Rawa ki te Whakapāpaku Intaglio whakamahia ai te Tinta Wai Intaglio mō te Plastik

Ka taea e ngā tinta whakapāpaku intaglio kua whakaputua ki te wai te whakaputa i ngā reanga iti rawa, e 5 ki te 10 microns ki runga i ngā kiri PE me PP, mai i te whakahaere pai i runga i ā rātou ake ngā āhuatanga rere. Kei te totohu tonu ēnei kōwhiringa wai ahakoa te tere tino tere ki runga i ngā pēhi whakapāpaku intaglio, e 80 ki te 120 mita ia meneti. Ko te totohu tonu ka awhina i te raru, pērā i te tinta e whānui ana rānei te nuinga o te pāpaku. I ngā tāpari, kua whakakaha ngā tinta katoa e 97.4% te whakauru tika o te tae, ā, kei te ū ki ngā ISO 2846-3 mō te whakapāpaku ki runga i ngā pāpaku plastik. He nui ngā kaihanga e mōhio nei ka taea e te paerewa e whai wāhi ki ngā maakete e hiahiatia ana te kounga.

Kua Whakapai ake i te Tinta Whakapiri ki runga i ngā Kiri Plastik Kāore he Pore

E ai ki te rangahau i te tau 2023 mō ngā āhuatanga here, ko te tinta intaglio waihanga heke i ngā hohonu e 92% kaha ake i ngā tinta noa i te whakamahia ki ngā taputapu PET me PVC. Ko te mahi whakapai ake nei i te raru mai i te koiora huinga huinga e kii ana ngā kairangahau ko te koiora huinga hibiri. E 26 ki te 32 mN/m te kaha o te pāpaku mata o te tinta, e 38% iti ake i te tikanga o ngā tinta tikanga. Nō te iti ake te kaha o te pāpaku mata, ka mawhiti te tinta ki te mātātā polyolefin kāore he hiahia ki te whakarite i te mātātā ki te mātātā corona motuhake i mua. Ko te tikanga tēnei ka taea e ngā kaihanga te penapena i te nui ake i te utu hauora, e iti ana i te 15 ki te 20 kWh ia tona o ngā taputapu kua whakarewetia.

Tauira Take: Whakapai ake i te tukatuka tā karawhiti ki ngā kōpaki kai whakawhitinga

Ko te kaihuri tōpahi i Ūropi i whakaiti i ngā tere take kaha mai i te 2,1% ki te 0,3% i muri i te whakamahi i te tinta intaglio wai mō ngā pūke retortable. Ko te rerekētanga o te nekeneke tākai i noho tonu i roto i te ± 0,08 i ngā huringa 50,000 mita rārangi ki raro i ngā tikanga kaha (60 ° C, 95% RH), e pā ana ki ngā whakaritenga ASTM F2029-16 mō te whakakī rongoā.

Te Ora Kaha me te Whakaeke i ngā Whakamahinga Tūmatanui

Ko te tinta tāwhai intaglio wai mō ngā pāpaku he kaha ki te kaha ki te kaha, e tino pai ana mō te whakakī i te whakaputanga ki ngā tikanga pīroiroi. Ko tana whakapiringa matua e whakaeke ana i te pānga matū me te wera wera wera wera.

Te Whakaeke Matū ki ngā Hinu, Hau, me ngā Kaitāwhai Hui-taapiri

Ko te pūpahi polimer o te tinta he aukati kaha ki ngā kai me ngā kai horoi i te pāpaku, he mea nui ki te whakakī kai kāore he hinu. Ko ngā tāpiri whakamātau e 98% te noho tātaritanga whakaahua i muri i te 72 haora o te noho ki roto i te hinu paraihe (ASTM F1306-22), e whakapai ake ana i ngā tinta plastisol tawhito.

Kaimana Whakahaere i raro i ngā Tikanga Roopu me te Wāpānga Tino

Ko ngā rangahau e whakaputua ana i ScienceDirect ka whakatairitea kua whakapumauia te whakapā ki te wai i ngā takotoranga takotoranga mai i te -30°C ki te 80°C, he tauwātanga matua mō te aronga kai me te wāpānga tropic. Kaua e whakapīroiroi i te kaimana kia kaua e rereke i ngā tikanga UV-cured.

Te Whakamahinga Roa ki te Whakapakonga Plastics Ahumoni me te Kaihoko

I ngā whakamātau whakakaha (ISO 15720: 2023), ko te tinta e toru kaupeka te kaha ki te whakapāpaku i ngā kiriata tātā. Kaua hoki e taea te 10,000 kaupeka kōpiko ki runga i ngā kiriata polyethylene kia kaua ai ngā tuhinga kia roa ki ngā kōpaki kia taea ai te whakamahi anō me te kuhu kaha.

Te Whakahaere Kaha ki ngā Tikanga Tāhinga Gravure Hōu

Ko te Viscosity me te Rere ki te Tāhinga Intaglio Wai Hōu

Ko te tinta intaglio waihangaia hei whakahaere i ngā whakahaonga gravure tere, me te rheology whakauru hei tere o te pana e 400 mita i te meneti. Ko ana tikanga tāpene he whakakaha i te whakapapa o te pāpaku ki roto i te 0.1mm, tae atu ki te tere tōaitanga. Kātahi ka iti ake te pāpaku e 19% tērā i ngā pūnaha pātai (FlexoTech 2023).

Iti ake te wā kua tāukane pana me te māmā ake te whakakapi i ngā pūnaha wai

He māmā ake te whakakapi i ngā tae, e kōrero ana ngā kaiwhakahaere e 35% iti ake te wā whakakapi i te mea kāore he toenga pātai. Ko te wehe atu i ngā wai pātai he wehe atu hoki i te hiahia ki te taputapu whakamāmātia e ārai ai i te rāwekenga, e whakaae ai i ngā kōtaha e 72 haora te roa kāore he whakamutunga i runga i te haumaru.

Ngā aronga whakauru mō ngā rereketanga intaglio kei te wā tonu

Ko te nuinga o ngā pana gravure e taea ana te huri ki ngā tinta wai ki te whakauru i ngā whakaritenga e toru:

1. Whakakapi i ngā taputapu pātai ki ngā pūnaha whakamahi wai
2. Whakaritea ngā kōnau o te pae rākai ki te 55°–60° hei whakapai ake i te neke atu o te tinta
3. Whakauruhia ngā wāhanga whakamātata irirangi e whakahaere ana i te 20–30% heke ake i ngā wāhi noa

Ko ngā whakapai ake nei e hokia ana te utu hoki ki te 14 marama te roa, mai i te iti ake o te huna hiko me te heke ake o ngā utu kaihoko.
