He aha ngā vantex e ōrite ana te tinta UV flexo mō ngā hiahia tuhinga maroke maroke?

Maroke Maroke Me Whakapaipai Tere: Me Pēhea Te Whakapainga UV Flexo Ink E Hiki Ai Te Uara O Te Printere

Ka hurihia e te tinta UV flexo te printere maroke maroke trūnga i te photopolymerization tūmatanui—ko te tikanga kei hea te ao UV e whakahohe ana i ngā hononga kimihana kia hangaia i raro i ngā hēkona 3. Ko tēnei aronga tere whakapainga e whai wāhi ana ki ngā wāhi pouhere matua i te whakaputanga ripanga, ngā rāwekenga pakanga, me ngā mahi print kikii.

Te mārama i te arataki pāpaku tere o te tinta UV flexo

Ko ngā tinta huinga-kaupapa e mahi ana mā te whakaputanga, engari he rerekē ngā tinta UV flexo nā te mea kei a rātou ētahi mea kiia nei ko ngā kaiwhakaara. Ina tūpono ngā mea nei ki te ao kapua-whero i waenganui i te 200 ki te 400 nanometra, ka hua ngā mea hihiri. Heoi anō, ka uru mai tētahi āhuatanga kimikimeko nonaianei ka huri te huinga ki te takotoranga taumira tino maroke, e kōrerotia hiki i te haurua sekene ki te toru sekene. Ka hua tēnei ina hononga ngā molekiula rerekē atu ki tētahi ki tētahi trāwhara te tikanga hononga-hohonu. Me tirohia hoki tēnei: kāore he kauwhanganui solvent e noho ana i muri i te tuhinga, kāore he mea e hiahia ana kia tatari kia maroke tonu te tinta, ā, he iti noa te tūponotanga o te tinta e pakaru ana ina whakaputangia ngā matapae tuhinga ki runga ki tētahi.

UV vs. ngā tinta huinga-kaupapa: Tētahi whāinga whakatairanga i te tere maroke me te pā ki te hanganga

Matua : Te tūhura a Packaging Europe mō te whaihua o te horapa UV
Ko ngā raraunga FTA e whakaatu ana ko ngā inka UV flexo ka hohonu 50 ngā wā ki te tere i ngā kōwhiringa parahi, ā, e whakaae ana i ngā tere takotoranga e piki ake i te 600 fpm kaua he uaua ki te kounga.

Ngā raraunga o te ao-iri: ka mutu te hohonu inka UV i roto i ngā sekeneha i raro i ngā tikanga pai

Ka taea e ngā kaituhi ngā wā hohonu katoa o 0.8–1.2 sekeneha mā te whakamahi i ngā rama UV 300–400 W/cm², ngā kamupene horapa ki te haumākuku, me ngā takotoranga inka kua whanaketia mō te rheology. Ko tēnei panoni tere e kore e hiahiatia ai ngā tūmanako horapa roa, ka tiaki i te 12–18 feet o te wāhi takotoranga ia takotoranga mā te upoko takotoranga arataki.

He tere tonu te horapa i ngā inka UV flexo katoa? Te tirotiro i ngā rerekētanga takotoranga

Mehemea ka rerekē te mahi:

1. Te tere o te kōwhiringa Photoinitiator (3–8% te tauwātata)
2. Ko te pākiki o te oligomer (ka whakawhitinga mā te mātauranga kia tere ake ngā harakeke iti-kiri)
3. Te rahi o ngā karu pigi (<5μm ka pouaka te mātauranga)

Ka eke ngā tohatoha matua ki te 95% kiko atamira i te takotoranga UV 200 mJ/cm², ā, ko ngā kōwhiringa tūtohi hoki e hiahiatia ana 350+ mJ/cm²—he utu hiko 75%.

Kua iti noa te wā kua pau me te parae nā te parai ake tūmatanui i ngā mahi tere

Ina hohonu ngā matērahi tūtata, ka whakamōhiotia ngā raru pērā i te miringa ki ngā kiri e pā ana ki te wera, ka aukati i te tā māwhitiwhti i ngā poro i te takotoranga anuanu, me te aukati i ngā upoko tā mai i te whatu i ngā inu māuī i mahue ai. Ko ngā tau ā-reo e kī ana he iti ake i waenganui i te 40 ki te 70 ōrau ngā matērahi i hinga ake i te nuinga o ngā tikanga tawhito, ā, ka iti ake hoki ngā takotoranga o ngā pihini umanga, he toru tekau ōrau iti ake pea. Ko ngā whakapai ake nei e nui ana te take, īt especially in food packaging operations where switching between different print jobs happens constantly throughout production cycles. The time saved translates directly into higher throughput without compromising quality standards at any point along the manufacturing line.

Te Kaupapa Pūtaiao mō te Hohoro UV: Te Whakauru Miro me ngā Wae Piki Tūmatanui

Me pēhea te Whakahohe a ngā Kaitōpū Mātau i te Whakauru Miro Maruaroa ki roto i te Tā UV Flexo

Ka houhia te tinta UV tere tonu nā ngā whakarewa kimihana i ara mai ai ngā taapiri motuhake e kiia nei ko ngā kaiihiata. Ina pāia e te ao UV, ko ēnei kaiihiata, pērā i ngā parahiko benzophenone, ka hura i te hiko i waenganui i te 250 ki te 400 nanometara, ka paku ake rātou ki ngā tuarangi noa. Ka tīmata ēnei kaipōkai iti i te tīmatanga i tētahi huinga o ngā kaupapa ka hono ngā monomer me ngā oligomer ki ngā whatunga herenga haangai i roto i te toronga haurua anake, pea tae atu ki te 1.5 hēkona. Ko te mea pai kiinei ko te kore he tumanako mō ngā solvent kia whakaputangia i mua i te neke atu ki te mahinga panoni. E āhua hokohoko ana ētahi rangahau hou ko ngā kaiwhakanao ina āhua rerekē te momo kaiihiata i āwhina ai i te iti ake i te hiko e hiahiatia ana mō te houhia e te 18 ki te 22 ōrau. He nui te take o tēnei momo uaua ki ngā toihau pepeha kei reira ko te wā he moni.

Monomers, Oligomers, and Resins: Tō Rātou Tūranga ki te Whaitua Pāmahana Maroke

Ko te aronga atu, te urupare hoki i waenganui i ngā monomers, oligomers, me ngā resins e whakahaere ana i ngā āhuatanga mahi a UV flexo ink:

• Monomers (hei tauira, ngā acrylates) whakauru anuanu tere ake i te wāhi e noho ai te viscosity (150–500 cP)
• Oligomers whakarato kaha pūtahitanga, me te whai mātaihiko acrylates e tuku ana i te hāpai pai ake ki ngā mātai polyolefin
• Mātai whakanui i te parairenga o ngā tioata me te roa o te kapa mutunga, kaore he whakarohe i te tere o te houhanga

Ko ngā raihana matūrangi e tuanui ana i te whakauru anuanu mōrearea i roto i te iti ake i ngā rua sekene kei runga i ngā mata takirua pērā i te BOPP me te PET, kātahi ka whakaatuia ki ngā whakamātautau ahumahi.

Ngā Hāngaitanga e Pā Ana ki te Rawa o te Houhanga

E toru ngā variaporo matua e whakatau ana i te mahinga houhanga o te tinta UV flexo:

1. Te kaha o te rama : Ngā punaha LED-UV e hoatu ana i te 8–12 W/cm² e āwhina ana i ngā tere raraunga 40% tere ake i ngā rama mercury tūmatanui
2. Te opaca o te tinta : Me te nui ake o te tāuta UV 25–35% ngā tioata mā paraunga i ngā tae takirua
3. Whakawhitinga mata : Ka whakawhiti ngā mata kōhatu i te 60–80% o te hiko UV, e here ana i te hīraunga o ngā kaipūmahara hiko

Kua whakapumautia e ngā tātari hou ko te whakauru i te kimikime mātai ki ngā roimata UV (UVA vs. UVV) e whakapai ake ai te kiko o te pūmahara ki te 30–50% mō ngā matērahi tapanga noa.

Kua Piki ake te Kawenga me te Whaihua ki te Taupeke Tere i te Taupeke Nui

Me pēhea te Whakamātau Tere e Āwhina ana i ngā Kawenga Tere Ake me te Tinta UV Flexo

Ka wehe te tinta UV anuanu i ērā wā pūaha kōhatu nā te mea ka whakaora tūmatanui ina eke ki te arahi UV. Arā, ka rere tonu ngā māhinī printi kaore he wāiti mō te horoi. Me horoi ngā tinta tawhito mā te hau, mā ngā tūnel kua whakapaihia rānei, tēnā e roa ana. Mā te whakaoratanga UV, ka oti te tētahi prosihia takirua noa, ka iti ake te wā e tatari ana. Kua ripoata ētahi toa i te itinga o ō rātou wā tirotiro mā te 70%, ahakoa ka rerekē ngā putanga e hāngai ana ki te tautuhinga o ngā taputapu. Ko te painga pono? Ka rere tonu ngā māhinī printi ki ngā tere tūpono neke atu i te 600 mita ia meneti. Ko tēnei momo tukanga e mahi pai ana mō ngā kamupene e hanga ana i ngā tapanga nui o ngā ripene, ngā taputapu pakete anuanu, ā, ko ngā paparanga anuanu hoki i reka ai te utu mō te wā kore mahi.

Te Whakatauira i te Tere o te Māhinī: Whakaoratanga UV vs. Ngā Tinta Tawhito

I whakaatu tētahi rangahau ahaunga printi 2023:

Kāore he whakaputanga o te paraihe, nō reira ka iti ake te wā e noho ai te tinta, ā, ka taea te pikinga o te kaha tukatuka 2-3 ngā wā i te huarahi arataki.

Te Tuhinga Tauira: I Te Hua 40% Ake I Te Piki Rua Ki Te Hangarau UV Flexo

Ko tētahi kamupene pakaranga i huri mai i ngā inka pātari ki ngā punaha UV flexo ki runga i ō rātou ono katoa o ngā māhinamana, i āwhina ai i te whakatika i ērā rerekētanga iti nei i tō rātou wāhi whakaputa tīkiti kai tio. E ai ki te Pūrongo Whaihua Flexo mō te tau 2024, ka arivea ēnei panonitanga ki ētahi hua tino pai. I piki ake te hua o ia marama umanga 40%, mai i te tekau mā toru miriona anuanu ki te tekau mā waru iratu mā rua miriona anuanu o te mātā papahoro. I iti hoki te nuinga o ngā rākau kua pau umanga e rua hautoru. Ko te take matua i pai ai ko te āhua o te whakapaipai tūmatanui, nō reira i taea ai te whakaputa tonu i ngā māhina mō te 22 haora tonu tonu. Ahakoa he nui ake te utu tuatahi mō ngā inka UV hou, i taea ano e te kamupene te hoki tonu i tō rātou moni i roto i ngā 14 marama takotoria i ēnei whaihua.

Te Tūmanako me ngā Painga Whakahaere o te Inka UV Flexo e Paipa ana Mātauranga

Te Whaihua Mātauranga me te Itinga Iti ake ki te Taiao o ngā Punaha Inka UV

Ka taea e te whakamātau ki ngā punaha inka UV flexo te iti iho te whakamahi hikoia umanga 60% mō te nuinga o ngā tikanga maroke tuku iho. Ko ngā tikanga tuku iho he mea rarahi hiko mō wā roa, tāpirihia ki ngā pūnaha horoi āhuarangi motuhake. Engari, ki te whakamātau UV, kāore he hiahia ki te hiko aukati, nō reira ka puaki moni ngā kamupene mō ō rātou nama hiko. He nui anō te painga nui ko te wehe tūmatata o ēnei inka. Ko tēnei mahi tere tēnei ka aroha atu te mīrau o te matapae e tu ana. Nō reira ka taea e ngā kaihanga te hanga pakete e iti ake ana, ā, he taumaha ake hoki. Ko ngā pakete taumaha ake, ko ngā putunga iti ake i te wā o te kawenga hoki. E ai ki ētahi rangahau, ka taea pea te iti ake i te waipuna karbona e pā ana ki te kawe tata ki te 18%, ā, e whai ana ki ngā tikanga motuhake.

Iti ake ngā whakaputanga VOC me ngā vantex mō ngā kaiwhakapāki B2B

Kua whakakorea e ngā inka UV te nuinga o ngā pūtangata waipuke (VOCs) i tēnei wā, he mea nui tēnei mō ngā toihau māpihi e noho ana rātou ki ngā ture EPA me REACH hoki ake nei. E ai ki ētahi tau maha a te ahumahi i te tau 2023, i kitea e ngā whakapakanga i huri ki ngā punaha UV kua heke ō rātou utu mo te whakakore haumaru ki te $74,000 ia tau. Anō hoki, kāore i pāngia e rātou ngā utu matotoru mō te kore e whai i ngā ture ka taea te tae atu ki te $240,000 pea. Ka tino kitea ngā painga i ngā ao pakihi pērā i te pouaka kai me te māpihi rongoā, kei reira hoki ngā tauira iti-kuhurutanga e tuku ana i ngā here o te FDA me ngā paerewa EU 10/2011 mō te haumaru o ngā matapae.

Te Aronga Ahumahi: Te Huringa Ki Te Whakamahi Inka UV me EB I Te Māpihi Flexographic Kua Hōhonu

Kua tipu te mākeke mō ngā tioata UV me te pūpahi inihana (EB) i te 22% ia tau mai i te tau 2020 ki te tau 2024. He aha te mea e hōpai ana i tēnei tipunga? Ko ngā punaha UV LED hoki, e iti rawa ai te whakamahi mātātoko. Kua kite ētahi tohunga o te ahumāra i ētahi nama ataahua hoki. Ka kōrero ngā kaihuri matua mō te whakatinga mahi e 35% tere ake i te wā e whakamahi ana i ngā kōwhiringa mā wai. Me te mea kei te mataara, ka whakahuatia e te nui ake o ngā kamupene ko ngā tikanga taiao te take matua mō te huri. E fiti tino ana tēnei aronga ki ngā paerewa ISO 14001, nō reira he mea mārama kei te huri atu te nuinga o ngā kamupene ki ngā tikanga UV flexography. Mō te ao pakitara in particular, kua noho matua pokapōkai ēnei tikanga hei whakapaipai i ngā whakaururanga e hiahia ana kia houa ake ngā hauora porowhita i roto i ngā huarahi tukutuku.
