Ko ēhea ngā Inka Tarau Kōpae e whakarite ana i te taurite o ngā pūtea mō ngā ota nui?

Te Take e Ngāwari Ana te Ngota Tahumaero i te Tā Hāngai Rahi

He nui te take o ngā pereki tinta e hāngai ana ki te utu me te āhua o ngā tohu mō ngā kamupene. Ina whakaputangia e ngā kamupene miriona ripihiri, he rite tonu te āhua o ngā ripihiri i te wā e huri ana te tae i waenganui i ngā pereki tinta rerekē. Ko ēnei huringa tae e arahi ana ki te mutunga o ngā mahi tuarangi, ki ngā mahi hoki e hiaho ana i te wā, me te whakapaea i ngā rawa kua pau. E ai ki ētahi rangahau, ko ngā raru e pā ana ki te kounga o te tapa e hāngai ana ki te 12 ki te 18 ōrau o te parae katoa i waenganui i te whakaputanga ripihiri. Ake ake noa atu i te moni i pau, ka pakaru anō hoki te kitea o te tohu ina kāore ngā tae e hāngai ana—nui ake ngā kaihoko e mātai ana i ngā tae ripihiri i te wā e rapu ana rātou i ngā hua ki ngā taonga hokohoko e ai ki ngā raraunga tūmatanui hou. Mō ērā e hanga kai, rānei rongoā, kāore i te nuinga o te āhua anake te hāngaitanga o ngā pereki tinta—ka titiro hoki ngā rāwekenga herehere ki ēnei mea, nā te mea ka taea e te tino kino o te tinta te whakapai i ngā takotoranga tiaki i ngā ripihiri, i ngā wā e taea ai te rere o ngā mea kino ki roto i ngā hua. Ka hinga anō hoki te tau ki te rahi o ngā pereki—ka tupono haere ngā iti iti o te uira tinta: he rerekē iti noa iho te 2% i waenganui i ngā pereki e hāngai ana ki te toronga 8% o te putanga tāpiri i muri i te tapa o te haurua miriona ripihiri. Nō reira, kāore ngā whakaputa matua e kite ana i te tino ū o te tinta hei mea tāpiri, engari he wāhanga taketake o tō rātou tikanga whakahaere kounga.

Ngā Āhuatanga Tinta Matua e Arataki ana i te Tikangia o ngā Tahumaero ki ngā Tinta Māpere Kōpae

Te tūturu o te uaua i runga i ngā haerenga tāpiri roa

He nui te take o te tika o te uira tinta i te whakahaerenga i ngā pihini flexo kikoi. Ina timata te rerekētanga i runga i ēnei roa roa, ka kitea mātou i ngā raru pērā i te tae e kore e ōrite me ngā hapa tuhinga e puta ana ki ngā wāhi katoa. I whakapuaki te Rōpū Rangahau a Ponemon i te tau 2023 ko ēnei raru e tāka ana i ngā kamupene hoko tonu e $740k ia tau anō mō ngā rawa kua pakaru noa. Ko ngā toihau mātau kei te whai ara maha hei whakatika i tēnei raruraru. Ka pupuri rātou i ā rātou tinta ki ngā wāhi whakauru e ārahitia ana e te wera, ka whakauru ki ngā kaitirotiro uira aunoa e tirotiro ana i ngā mea i te wā hianga, ā, ka mahi tahi hoki ki ngā harakeke e tino mau ai ake i raro i te whakarereketanga. He aha te mea e whai hua ai kia katoa tēnei? Ngā panui tinta e whai whakaahua pai ana mō te ara e rere ai me te noho ai. Ka āki ai ēnei īnanga i ngā pigment kia kaua e heke i raro, ā, ka āki hoki kia ōrite te takotoranga ake i te wā e neke haere ana te tinta mai i ngā rori anilox ki te whatunga e tuhia ana. He atonga atu, ka iti ake te putanga e hia hia haere ai ngā kaimahi ki te horoi i te katoa i waenganui i ngā turanga umanga e 30%.

Te ūrite o te parairenga o ngā raihana me te tōrite o te rheology

Ko te parairenga pai o ngā raihana e whakarāwekanga ana i te kaha o te tae me te kore-ataahua i ia wā i te huinga i te huinga. Ka hinga ngā raihana ki te kohikohi kore ū, ka hinga ai ngā raru i te whakarāwekanga a te tinta e nekeneke ana i te pēra. Ka taea e ngā tikanga pūhui hōu te eke ki ngā rahi pūtau iti ake i te 5 mikirona, i te wā e pupū ana te pūtahitanga o te zeta e pā ana ki te ±2 mV. He mea hoki ake te mea nui ake ko te āhua pai o te hokinga mai o te tinta i muri i te pānga ki ngā kaha tōpiko i te wā o te tukanga. Ko tēnei momo tōrite rheological e whakarite ana i te ūrite o te tāwhai tinta, ā, ahakoa he aha te tere o te pēra i te wā o te huinga. Me whakauru ētahi whakapakari motuhake ngā tinta mā te wai kia kaua e pakaru te parairenga ahakoa he aha te rerekētanga o ngā rārangi pH. He mea tino nui tēnei ina mahi ana ki ngā matapae whai ahuatanga pērā i te papakupenga papakupenga, i reira ka taea e te kore-ū o te tinta te ruine i te kounga o te takotoranga.

Te Whakatau i ngā Inka Tā Tārai: Te Mahi o ngā Inka Pātai, Inka Kōpae, me ngā Inka Kua Whakapiri UV

Te tāwhai hoki o te pātai ki te pātai mō ngā kimikime o ngā inka

Ko ngā inika pāpaku e tu ana ki te wai e whakaatu ana i te tino ū ā raro i te whakangao kia ū ake, nā te mea kei te tino ū tonu te wehe o rātou, ā, kāore he nui te lossinga paraihe i te wā o te penapena. E ai ki ngā rangahau e meatia nei e te Rōpū Ponemon, kua parenga ai ngā huarahi e tu ana ki te wai i ngā raruraru kounga umanga 32 miriona taurunga atu i ngā hua e tu ana ki te paraihe. Heoi anō, he nui ngā raruraru a ngā inika e tu ana ki te paraihe ki te pupuri i ngā hua ū tonu. I te wā e mawa ana ngā VOCs, ka huri te kōnehu puipui tahi ana ko ngā āhuatanga rere o te inika, arā ka hiahiatia e ngā kaituhi te whakarerekē i ngā tautuhinga i waenganui i ngā kapuni. Ko ngā inika UV e hāngai ana ki te waenga e pā ana ki te ū tonutanga. Ka hāngai tēnei taima, kāore he taima e tatari ana mō ngā wā horapa, engari he nui te painga o te mahi ki te āhua o te mārama e hoatu nei e ngā rama UV ki te rohe tuhinga katoa. Mō ngā mahi matua herekore kei te tika te tae, ka taea e ngā inika e tu ana ki te wai te tiki i ērā rokiroki tae Delta E (kei te paku rānei 0.3) tino pai, ina koa ki ngā taputapu pēra i te pepa, te karatapu. Ko ngā inika UV ka pai ake ki ngā kiriata pāriha, kia tika katoa ngā atanga o te tikanga hāngai.

Ngā whakahaere tukanga e whakapumautia ana te tika: mai i te wero ki te hipoki

Te arotake mātai i te pīkioka mōhiotia mō te whakahaere inka kati-karaka

Ko te arotake i te pīkioka mōhiotia i te wa katoa o te kaupapa whanaketanga e āwhina ana kia tere ai ngā whakatika mā te whakamahi i ērā punaha tuku mātai kua kōrerotia e tātou kē nei. Ko te punaha katoa kati-karaka e pupuri ana i te aronga tika, e stop ana i ngā huringa tae hekeke, ā, e iti rawa ana i ngā rauemi kua pau pea 18% nui ake i ngā panonitanga ā-ringa. Kei roto inaianei ngā taputapu arotake i roto i ngā raina tuku inka, e kohikohi ana i ngā raraunga rerehua i ia wā. Ina timata te wehe haere o ngā panoni atu anō i taua rohe +/-5%, ka tūtomatia te punaha me te nuinga tika o ngā taupā e hoki ana i te katoa ki te ara.

Ngā tikanga QC whakauruatia mō ngā inka tuhinga takotoranga marawhara i mua i te hipoki

Ko te whakamātau tōkirikiri i mua i te hānganga e whakapumautia ai ngā aratau taketake mō ia kapu tinta. Ko ngā tirohanga me matua kāwhai hea ko te āhua o te pāpaku ki te whirikōhatu, te nekenga o te kaha o te tae ki te karuhirotometara, me ngā tātai aunoatanga o te pāmahana i roto i ngā wā 24 haora. Kātahi ka iti ake te ōrau whakakorenga i ngā tinta rerihi pēpihi 30% nā te kitea i ngā take e pā ana ki te hanganga i mua i te timata o te pāpā.

Ko ngā pūnaha tuhinga aunoa e waihanga ana i ngā ara ārotake mō ia whakaritenga, ka taea ai te tātai i te take matua ina heke mai ngā whākinga. Ko tēnei ara pūnaha e hoatu ana i te mahi taurite ki ngā huinga e piki ake ana i te 10,000 mita raina.

He mea nui te taurite o te tinta i te tuhinga whakapae nā te painga ki te kounga o te tuhinga me te kitea o te tohu. Ka taea e ngā huinga tinta e kore nei e taurite te āhua o te tae me ngā hapa tuhinga, ka whakarereke i te whakapau me te mātai rāwekenga.

He aha ngā wero e pā ana ki ngā tinta pātai?

E pā ana ngā wero ki ngā tinta pātai pērā i te whakaputanga o ngā VOC, e huri ana i te nekeneke o te pigment me ngā āhuatanga rere, e here ana i ngā kaituhi kia whakarereke marino i waenganui i ngā huinga.

E hia te putanga me whai mātai te nekeneke o te tinta?

Me arotake tonu te pātata o te tinta i te wā o ngā rāwekenga whakaputa, mā ngā pūnaha whai mōhio-ā-wā-tūmatū e taea ai te whakatika tūturu kia mau ai te rite.
