He aha te mea e pai ai te tinta Flexo mō te tuhinga ki ngā ipu pepa me ngā paruhi pepa?

Te Ōrite o te Tino Matua: Me pēhea te herehere o te tinta Flexo ki te paperboard porohe

Ngā Tikanga Herehere ki ngā Rangi Whaiaro Porohewa

Ko te tinta Flexo e mahi pai ana me te pepa pūpahi nā te whai wāhi o te āhua parurenga o te matēria. Ka uru tere ngā tinta ki roto i ngā putake mā te mahi ariari, i te wā e hukihuki ana ngā kararehe tae ki ngā huinga cellulose kei roto i te pepa. Ina whakarerekētia e ngā kaihanga ngā rēhinā acrylic, ka hangaia he hononga kīrearea ake i waenganui i te tinta me te mata o te pepa. Ko ēnei rēhinā kua rerekētia e hanga ana i ētahi hononga kimikime hāpori ki ngā rōpū hydroxyl kei te mata o te pepa, arā ko te tikanga, ka mau tonu te takotoranga tuhinga ahakoa ka pouri, ka maroke rānei. Ko te takotoranga atamira o ngā hononga tinana, kimikime hoki e tiaki ana i ngā takotoranga tuhinga kia kā, kia kaua e māmā, he mea nui tēnei mō ngā hua pērā i ngā kōpaki inu e noho ana matou i ngā tikanga pouri. He uaua ake te papahono kua whakamahia mua nā te mea e neke atu ana i ngā wāhi iti me ngā mata kore āhuatanga i ngā whakamahinga o mua. Ko te wāhi reka ana te nano-silica. Ko ēnei partihiria iti e kapi ana i ēnei wāhi kaua e kino i te kounga o te takotoranga, nō reira ka taea āna toa te kiri ataahua aha anō i te whakamahi i ngā matēria kua whakaputangia.

Whakarerekenga me te Whakarereketanga o te Rerehu hei Whakauru Tika i te Tinta

He nui te take o te tika o te rerehua whena ko te whakamātautau i te tinta ki ngā paparorohiko parureka, kīato e rere ana i ngā pihini ki ngā tere tino pai. Ko te wāhi pai mō te uaua kei waenganui i te 0.1 ki te 0.5 Pa.s e hia mano ngā sekene i te 10,000. Ka pupuri tēnei rohe i ngā karuwha kia tū tonu, ā, ka whakamāmātia anō te tinta kia ōrite ai te totohu, e awhina ana kia kaua ai e rerekētia ngā tohu takirua, i ngā raru hoki pērā i te kōpae. Ina mahi ana me ngā kaiwhakapai pseudoplastic, ka heke te uaua ina tuhinga ana te pihini i te kaha tuarangi, he rerekētanga nui hei āhua māmā ki ngā mata e iti ana te kaha mata, e haurua ai i waenganui i te 32 ki te 38 mN/m. Heoi anō, he nui ake te mea. Ko te tāpiri i ngā kaiārai pH e awhina ana kia pumau ai ngā emulsion acrylic ina uru ana ki te matā. Me kaua hoki e wareware ngā kaiwhakarere—ēnei kaiāwhina iti e whakarerekē ana i te kaha arawhata kia puta ai ngā kiri tinta e 1.2 ki te 2.4 grama per mita tapawhā, kāore he whiu mō te rere tinta, kāore rānei i te ngaro i te korekoretia. He mea nui rawa ēnei take kia tutuki ai ngā paerewa pakitara kai, kia iti ai ngā utu mātai i ngā huinga whakangao.

Whai mātaitaka Kai: He Inka Parurenga Pāpāwai e Ū Ana ki ngā Paerewa Ture

Whai mātaitaka FDA, EFSA, me EU 10/2011 mō te Whakapā atu Raihe ki te Kai

Ko ngā inika whakapapa wai e whai ana i ngā tikanga katoa e pā ana ki te kai i te ao, tae atu ki ngā here mai i te FDA i raro i ngā wāhanga 21 CFR 175.105 me 176.170 e pā ana ki te whakapā atu takotoranga, tā te whakamātautau haumaru mai i te EFSA mō ngā matēriau kai-tika, me te Ture o te EU 10/2011 e tautapa ana i ngā roa whakawhitinga mō ngā kai hiriwa. He aha te mea e wehenga ai i ēnei inika i ngā kōwhiringa pūtau? Kāore anō kia mau ngā kaiārahi tia kiri, ngā metara matara kino, i te pūtau i mahue ai e taea ai te whakawhitinga ki ngā hua kai. Kia tūpono kia noho haumaru katoa, ka whakamahia e ngā kaihanga ngā tioata me ngā kaiwhakakō pikari i tīpakohia ai kia kaua e rere ki waho i te wā. Kei te nuinga hoki ngā whakamātautau e pā ana ki ngā tikanga pērā ki ngā inu wera i te 90 wārangi Celsius (neke atu rānei i te 194 Fahrenheit) me te whakauru ki ngā tikanga pūkenga reka. Me noho tonu ia wāhanga i raro iho i te roa tino 0.01 miramira pera ki te manokarama mō ngā whakamahinga e pā ana te inika ki te taha o ngā hua kai.

Ngā Hōputa Pakaru Mōhio me te Whakaiti i ngā VOC kei ngā Inika Flexo Kua Ora Nekehia

Ko ngā inika flexo hōtaka wai i tēnei wā e whakauru ana i ngā hanganga paraihe motuhake e pakari ana ki ngā pārtihikara pigment, ka whakaiti i ngā rūnanga pakaru ki te 97% tata ki ngā tikanga tawhito. Ko ngā kohinga takotoranga takitahi (VOC)? Kei te iti ake i te 1% o ngā kai e whakamahia ana i ngā hua e huri ana ki te paraihe, ā, ko tēnei pea e ū ana ki ngā paerewa maroke o te Pūrere Air Resources Board o California me ngā here taiao o te ao mō te ahumāra o waho. Ka whakakapi te hōputa i ngā glycol ethers ki ngā kōwhiringa haumaru ake e taea ai anō te maroke tino tere, he itinga noa iho te wā e maroke ai, āta neke atu i te hauwhā hākari hoki ki ngā rārangi hōtaka tere. Me tētahi mea nui mō ngā whakapau kaha whakarewa i ēnei rā—kāore ngā hōputa hou i roto i ngā kīmika halogenated. Arā, ka tutuki tonu te hua pepa, kāore e kirihou te tāonga paparorotini i te wā e whakarerekē ana, ā, ko tēnei he mea tino nui ake i te wā e pakari haere ana ngā ture taiao ki ngā umanga katoa.

Whakapainga me te Whakapūmau: Tōtika i te Kawenga, Kiko, me te Pūmahara o te Papanga

Whakapainga mā te Whakawhitinga Mōmona mō ngā Kopi Papatēpu ā-Tinana e Mataara ana ki te Wera

Ka whakapainga te tinta waiaroha pene hinu mā te whakawhitinga whakahaerenga, nō reira he pai rawa mō ēnei kopi papatēpu paroi e mataara ana ki te wera. Kei te pai rawa te tikanga ina noho ngā wāhi i waenganui i te 40° C ki te 60° C. Ki ēnei rāwekenga, kāore he mōrearea o te kowhiringa i ngā kopi, te pā ki te ahi, i te ngaro i ō rātou āhuatanga whakamātau i ngā hoahoa kotahi pā. Inaianei, ka whakamahi ngā punaha hōu i ngā kaitirotiro taumaha mō te raina kia tika te wā whakapainga. I āwhina ai tēnei i ngā kaihanga kia piki ake i te 25 ki te 27% i ō rātou cikara whakaputa e ai ki ngā ripōtere ahumahi. Anō hoki, kāore he pauna VOC e puta mai ana i tēnei tikanga anō. Ko ngā kopi ka hua mai e pā ana i te āhua pai, kāore e rere, ā, whakaaria tonu ana ngā āhuatanga wera pai i te wā o te whakamahi tūmatanui.

Ko ngā Kōwhiringa Tinta UV/LED Flexo mō te Whakaputa Marika, Iti-Kiko

Ina honoa ngā tinta flexographic e whakapungaweratia ana e te ao hauauru me te hangarau LED, ka tīmata takitahi te whakapungaweratanga mārurenga o ngā pihareta, ā, ka taea e ngā pihareta te rere ki te 300 mita ia miniti, he take i te 80% tere ake i ngā tikanga tawhito. Ko ēnei punaha LED UV e whakamahi ana i te 60% iti ake i te hiko i te nuinga o ngā rama mātātoko mātātoko, ā, e tuku ana i te wera inarotahi kāore i te tino. He mea nui tēnei ina tapa kōhatu ana ki ngā mea pērā i ngā paripari pepa māpihi e waro ana ki ngā pūngāwera noa. Tētahi anō hoki he mea nui ko ēnei punaha e hua ana i te kore atu i ngā karaihe organik e pā ana, nō reira kāore he hiahia ki ngā umu tōmuri hāngai e noho ana ki te wāhi i ngā rārangi whakaputa. Ko te putanga? Ngā pikitia e manawa tinihanga ana i ngā porotoko i te wā o te tuku me te whakahaere, i te mea anō ka itinga te huaka karbon mai i ngā mahi katoa.

Mahi Tatau Tatau: Te Manawaroa i raro i ngā Tikanga Ao Tūmatanui

Ko ngā inika Flexo i hoahia mō ngā tono matatau kia mau tonu te āhua pai o ngā taua i te wā e ora ana ngā ipu pepa me ngā paripari. Ka taea e rātou te whakahaere i ngā momo wero katoa pērā i te pouri mai i ngā inu makariri, te matekuka mai i ngā inu wera, te wareware haere pea i te wā e huinga ana, e neke ana, me te whakamahau ake e ngā kiritaki. Ko te ara e piri ai ēnei inika ki te pepa ki te taumata marokore ka whakakore i te ru, te peka, i te māmā, ahakoa kia hia hoki ngā wā e rū ana ki ētahi atu pakete i te wā o te tuku. Ko te mea nui rawa kei konei ko te mahi pakari nei e kore e pa ki ngā paerewa haumaru kai. Ki te taumata molekiula, ka piri tāngata te inika ki te mata kia kore rawa atu te mōrearea o ngā kimikime ranei e neke ana ki roto ki te kai e pā ana ki aua wāhi kua tuhia.

FAQ
