Ngā Āhuatanga Tere-whakapai Me Tōna Whai Pānga Ki Te Whakapai Tere O Te Whakaprint

Me pēhea te whakapai ake i te whakapai i te whakapai tere o te whakaprint flexo

Kei te whakakore ngā rairopi tinta flexo tere-whakapai i ngā kōpōpō e hinga ai i te wai e toe ana, e āki ai ngā toihau whakaprint ki te eke atu 18–24% teitei ake te tere o te whakapai kia tāwhai ai i ngā tinta hāngai. Ka taea e ēnei tinta kia kaha ake te tere o ngā pana ki te 600 mita/meneti teitei ake rānei kaore i te whakarupeke i te kounga tuhinga, na te iti i ngā wātā i waenganui i te tuhinga me ngā mahi e whai muri ana i te tuhinga pērā i te whakapae, te whakapae rānei.

Ngā Tikanga Whakamātutu: Whakaputua, Whakauru, me te Whakamātutu UV

Ko ngā raihana māmā o te wā nui e toru ngā tikanga whakamātutu matua, e kauwhata ana ki ngā kaipapa motuhake me ngā hiahia whanaketanga:

Kei te whakapai ake i te wā whakamau kia 25% ia 6°C te pikinga o te pāmahana , i te wā kotahi ka eke ngā tinta UV-cured ki te whakatinanatanga o te polymer i roto i te iti ake i te 0.3 hēkona. Āwhinatia ana tēnei whirinakitanga kaihuri kia whai rite ai i ngā tikanga whakamau ki ngā whakaritenga mahi i te wā e whakauru ana ki te mahi tere.

Te Whakapāpaku me te Kounga Otinga o te Tinta Tere Whakamau

Ko te tere whakamau tinta e iti iho ana i te rerekētanga o te whakapiki pāpaku ki te iti ake i te ±1.5%, ka tūtohu ai i te kounga tā rite e hiahiatia ana mō te whakauru toa. Ko ngā rairopi tere whakamau hoki e whai ana 40% te whakapā ki te tinta e tō ana i te wā hurihia ai te pōro, e pōpō hoki ana te pāpaku mai i te kōpāpaku, te kōpāpaku rānei i ngā mahi nui.

UV-Cured Flexo Inks: Tere Whakatinana me te Whakapāpaku Rerehua i ngā Tere Tere

UV-curable vs. ngā rairopi tinta pāmahana: Te Whakauru i ngā taiao tere

Ngā inki UV-curable flexo e pai ake i ngā kōwhiringa eke hau ki ngā tono tere nui nā te whakapapa tere o te whakapapa UV. Kāore he hua o te mawhakihaki, e tāpiri ana i te wā māmā 15–30%, ā, ka tautoko ngā inki UV i ngā tere pēhi e piki ake i te 600 feet/minute—40% tere ake i ngā punaha eke hau—ā, kei te tiaki i te whakapākehātanga pāpā (Market Data Forecast 2024).

Te whakamāmā i te kātata me te thixotropy: Me pēhea te urupare a ngā inki UV flexo ki ngā tikanga kātata teitei

Ko ngā inki UV flexo i tēnei wā e whakaatu ana i ngā āhuatanga whakamāmātia tōnuitia. Ina tāpirihia ki ngā āhuatanga tōnuitia teitei e 10,000 takotoranga inverse e kitea ana i ngā rōpere anilox, kei te heke te uaua o te inki mai i te 60 ki te 80% e ai ki ngā rangahau hou a Zeller+Gmelin i te tau 2023. He aha tēnei e aronga ana? Kei te rere tino pai ake te inki ina hōu ake ngā rōpere i te 1,200 RPM, e āwhina ana kia kaha tonu te haere kaore hoki te whanake o te nebuliser. Ā, he āhua atawhai anō hoki: ina tāpirihia ki te papanga, ka hoki anō te inki tino tere. Ko te 85% o tana rahi tuatahi e hoki mai ana i roto i te 50 milliseconds anake. Ko te hoki tere ake i te rerekētanga nui ki te whakapūmau i ngā tapa totohu me ngā raina horo, ahakoa te taupānga inki rānei te papanga, he uaua rānei ki te whakaputua.

Te whakapūmau i te pūmahara o te uaua me te hoki mai o te inki i waenganui o ngā kawe papanga

Mātai tonu te pūmahara o te UV, he iti noa te rere o te kaha o te iti ake i te ± 5%, i te wa e 8 haora ana te whakangao, tērā i te 15–20% e neke haere ana i ngā pūnaha pātai. Ko te tūpono o tēnei ka āwhina ki te 22% te penapena i te mātai mō ngā mahi whakauru pakonga pakari (Raraunga a Pira International 2023):

Ngā ōwe o te whakapai tūturu ki te hangarau UV i ngā whakamahinga tere

Ka whakakorekia e te tukanga UV te pupuhi, e āki ai te tukatanga i muri i te whakaprintia tūturu. Kaore he tāone e 70% mo ngā pakihi papai rongoā, e tiaki ana i te whai i ngā tāura FDA 21 CFR 174.5 mō te <0.1% o ngā toenga pupuhi.

Ko te nekenga ki ngā inki tōka mā te wai e hāngai ana ki ngā kaupapa aratohu taiao pērā i te whakahaere REACH o Ūropi me ngā here o te Ture Hau Tāone Tāclean o Amerika. Kei te whakakaha ngā ture nei i ngā kaihanga kia iti ake te whakaputanga o VOCs nui ake i te 95% tērā i ngā tikanga kua whakamahia i mua. Kua wātea kē ngā tikanga mā te wai e hawhe katoa o ngā tono inki e tautoko ana i te taiao, ā, ka aki ake pea tēnei tau ki te tau 2025. He aha te āhua whakamāharahara o ēnei inki? Mā wātea i ngā kamupene te whakaputa i ngā taputapu pakonga e haumaru ana mō ngā katoa mai i ngā pokapu reka ki ngā pātī wai mā te iti i te kounga. Kei te tāwā tonu te hiahia ki ngā inki tōka mā te paraihe tētahi 18% mai i te rā tuatahi o te tau 2020 nō te mea kei te uaua ake te utu mō ngā kamupene kia rite ki ngā aratohu ake anō hoki ki te whanake ake o ngā mōhio ki te haumaru o ngā kaimahi e pā ana ki te noho ki ngā kikorangi.

Whakarāpopoto Mahi: Water-Based vs. Solvent-Based Flexo Inks

Ko ngā tinta mā te wai ka toa tonu ina tōa ai ki te taiao me te haumāmā o te wāhi mahi, engari kei te whakapātata ana. Kei te roa ake te rere atu i te rā, arānei ka whakahaere ngā pana tākupu i te 20 ki te 30% i ngā wā tere kei te taima e hiahiatia ana te tere. Ko tētahi atu take ko ngā tinta kāore he whakapipi rawa, kia kaua e pakaru tika ki ngā papanga māmā, pērā i te pāpaku, kāore anō pea kia whakaritea. Engari, ko ngā whakapai ake i ngā tau kua pahure ake nei i te ara i āwhina ai i te āhua o ngā rāwekenga. Ko ngā whārite o nāianei ka tū kia pai ake i ngā whārite tawhito ina tōa ai ki te herekai me te āhua o ngā tae i muri i te ta.

Te Whakawātea i ngā Uara Whakarewa me ngā Whakahaere Pana i ngā Tautohe Tere

Ko ngā kaitauwhiri e whai whakama i te whakamātao i ēnei wā kua tīmata ki te whakamahi i ngā rākau hau pai ake me ngā whakamātao mātātoko inereti. Āwhina i ngā taputapu kia tere ake te whakaputanga o te wai i te wā e tiaki ana i ngā kiri tino māmā. E ai ki ētahi rangahau i te tau ki muri, ina whakarerekētia ngā rerekētanga o ngā whakamātao mai i te 15 ki te 20 neketa Celsius te wāruruhanga, kua rere ngā rārangi hui tata ki te 12 ōrau tere ake mō ngā whakaprintia kua hangaia ki te wai irirangi ki ngā taputapu polietilēni. Kei te kitea hoki e mātou he mea hōu - ngā rairopi takotoranga koiora e whai ana i te hangarau UV tahi ana ki ngā whakautu wai irirangi. Ko te tikanga ka tango i ērā anō ngā mea pai ki te taha katoa: te whakahaere i te taiao ki te wai irirangi tā te tere o te whakamātao e hua ana i ngā tikanga UV.

Te Whakakaha me te Kounga Whakaprinti ki runga i ngā Tātaritanga Rerekē

Te Mahi a Flexo Ink ki runga i ngā Taputapu Plasti, Papatuhi, me ngā Kiriata

I tētahi rangahau hou i te tau 2023 kua tirohia te mahi a ēnei inu, ā, kua kitea mai kia eke kia 40 dynes per square centimetre pea te kaha o te mata, ka pakaru ki te 95% te ōnā ki ngā mata polietilēna. Mō ēnei mata kōtiro kauwhata, pērā i ngā kiriata hōu, he pai ake ngā inu tōaitanga UV cured flexo nā te mea ka maroke tonu rātou ka aukati i te rere o ngā tae. Ka tiakina e tēnei maroke tere te kounga tae i te 98% te rite tonu, tērā i te 84% anake mēnā ka whakamahia ngā tikanga kua whakaurua ki te whakaputanga tere. He mārama te nuinga o ngā kaihanga e huri ana inaianei.

Te Whiwhi i te Pakaru Tūturu ki te Pakonga Kaha i ngā Tikanga Tere

Kei te hiahiatia ētahi tinta mō ngā pani pāpaku tere (300–600 m/min) e hiahiatia ana i te wā poto kia hangaia ai te kiriata me te rerehua tāpoi. He māmā noa te whakaiti i te uauatanga o ngā takotoranga takai-tai 62% tērā i ngā tinta tūmatanui (2022 Flexo Adhesion Report), ka tūtohu ai i te nekehanga tāpiri ki runga ake i te 500 m/min. Ina kotahi tēnei ki te arataki uauatanga tātai-tātai, ka eke ngā tinta ki te ~ 0.5% whakarerekētanga taumata i runga i ngā huringa hui 12 haora.

Te Kōwheinga o te Kaha o te Arapeka ki te Hononga Tinta me te Roa o te Tāhanga

I whakaatu mai i te 2022 Te Whirinakitanga o te Whirinakitanga ko te whakakaha ake i te kaha o te mata o te kōwhiringa kia 15–20 dynes/cm² ka whakapai ake i te whirinakitanga tinta kia 300% i runga i ngā kiriata polyolefin. Ko te whirihau i te kaha o te mata tinta ki te kaha o te kōwhiringa (ki within ±2 dynes/cm) ka heke i ngā ngoikera kiriata kia 73% i te whakapakonga whā ki te kai.
