Ngā Painga o te Kiri Tapetape Kaha

Te Pakari ake me te Tiaki i ngā Mea Mekameka

Ka piki ake te roa o te wā o ngā takotoranga mā te whakamahi i te kiri tapetape kaha

Ka taea e te mātai here here taia rite te whakakaha i te ora o ngā tūhinga tapa kia toru ngā wā atu i ngā putanga noa, kāore anō hoki i taia. Ko te mea e āki ai tēnei ko te herekore tino pai ki te mata e whakaputangia ana, nō reira kāore he wehe mai ahau i muri i te nuinga o te whakamahinga i te wā roa. Ko te ara motuhake e hono ana ngā polymer tēnei ka tukuna atu he kaha atu anō. I whakaatu ngā rangahau ki ngā matērihi pērā i ngā whakapai ake i waenganui i te 20% ki te 35% i ngā takotoranga ao-iri, arā ko te tikanga e mau tonu ana ngā mea tino roa ake i te tīkanga.

Te angamahi ki te parurenga, ki te korengatanga, me ngā take taiao i ngā matērihi i taia

I mōhiotia ngā mata i taia he iti ake te 97% ngā parurenga ata kiteka i muri i te whakamātautau parurenga paerewa (ASTM D1044). Ka tiaki te takotoranga taipō a-matauranga i ngā pakanga ki te huamua, ki te ozone, ki ngā kirihou kei te rangi, ka mau tonu te mahi i ngā wāhi tino makariri mai i te -40°C ki te 120°C.

Kaha ake, manawaroa ake hoki ngā matērihi i taia i raro i te kītoitanga mekanik

Ko ngā matapae kua tapiri 5X te manawaroa ki te pikinga (40 N/mm²) me te manawaroa ki te ripa e 8X ake i ngā punanga kāore i whakaritea. Ko te take, ko te āhua o te kiriata ki te whakarere i te pēhanga mekanikia mā te mata katoa nā te huinga karaihe paraire kua honoa.

Te tino rahi o te kiriata kua tapiri me te tino pūmau o te hanganga mō te mahi roa

Ko te rahi tino pai o te kiriata (25–250 μm) e taurite ana i te maroke me te tiaki. Ko ngā kiriata penei (≥150 μm) e 62% pea te whakaiti i te haerenga o ngā arawhenua i ngā whiu whiu, i te wā e mau tonu ana i te itinga ake i te 2% i raro i te pēhanga, nō reira he mea tino pai mō ngā whakamahinga pakuhi pakuhi pērā i ngā ripanga umanga me ngā takotoranga mātātoko.

I whakaatu ngā whanaketanga hou i ngā epoxy nanocomposites i te āhua e taea ai ngā whanaketanga hou i ngā raihana kiriata ki te piki ake i te 50% i te kaha unuhanga i ngā kowhiringa tuku iho, ka whakapai ake i te mahi mekanikia.

Te Tiaki Tino Pai i ngā Tā me ngā Hoahoa

Te tiaki i te kaha o te tae me te maaramatanga o te tā mā te kiriata kua tapiri kaha

Ko ngā pene tāpahi me ngā here here kaha e rākau ana i te 99 miriona o ngā anuanu kino a UV, e āwhina ana kia kaua ngā tae e mātara. E ai ki ngā whakamātautau ahumahi i tirohia i ngā Rangahau Tiaki Arataki Tāpiri, ko ngā tāpiri e tiaki ana i ēnei pene e pupuri ana i te 94% o ō rātou tae takitahi noa i te wā e 18 marama i te rā. He mea hira tēnā ki te whakarārangitia ki ngā tā noa e pupuri ana i te 62% noa o te kounga tae i te wā e 18 marama anō. Ko te maru aro-ātaahua hoki he mea hei tohu nā te mea e 92% atu rānei o te ātaahua e tukuna ana e te nuinga o ngā pene kounga, ā, he iti noa te pereketanga (he iti ake i te 1.5%) ahakoa pērā pea te teitei o te hūmātai. Arā, kei te maama ake ngā kupu tuhituhi me ngā whakaahua, ā, e uru pai ana ki te pānga ki ngā tikanga taiao.

Tiakitanga i te tā, i ngā rahinga hoahoa mai i te parihau, i te pānga kimikimi

Kua nekehina pea ngā kiri ā-papa ki te 83% ina tāpirihia ki ngā takotoranga noa ina whakamahia ngā tikanga a Taber. Arā, ko ngā kiri nei ka hanga i tētahi papa tiaki kaha e āki ai te māmā o te tā, ā, āno he maha ngā wā e whakapā ana, e wehe ana hoki. Whakaarohia ērā tapa whakaputa e taraiwa ana i ngā takotoranga o te utu anuanu anu, e 50 wā pea ia rā! Anō hoki, kua pakari ki ētahi atu mea pērā i ngā matimati mātukutuku, ngā horoi kaha, ngā huringa pouri, me ngā tōkotoko i te wā tonu o te arataki. Mō ngā tapa reka, kua whakaatu ngā whakamātautau ko te korero tāpiri ka mau tonu ia, āno he toru rā e noho ana i roto i ngā wai, mai i te taunaha tino whangai (pH 3) ki te taunaha tino parurenga (pH 11). Ko te kaha o te kikoikoi e pai ana mō ngā mea pērā i ngā pīni inu, kia kore ai e mā te tā, ahakoa kei ngā whare pakuhi, kei ngā whare taiwhanga rānei e tiaki ana i ngā matū.

Whaitua Mahi ki te Puna, UV, me ngā Matū

Te Manawaroa ki te Mātai i ngā Taupatanga Pakihi mā te Whakamahi i te Kiri Tapetapenui Āhua Kaha

Ko ngā kiri tapetapenui āhua kaha e wāwahi ana i te pātai nui o te mātai kia kaua e tūhono atu. Ina titiro mātou ki te hanganga o ngā pakihi kai, ko ngā mea e hono ana i ngā takotoranga PET me PE e muhi ana i te hōpūpu waimānuka e tata ana ki te 98%, he nui ake te pai i te whakamahi i tētahi takotoranga anake. Mō ngā mea pērā i ngā rongoā e hiahiatia ana kia maroke rawa (i raro i te 5% mātai) i ngā waahanga hiko hoki e pāhu ana mā te pātai, he nui te take o tēnei momo tiaki. E ai ki ngā raraunga a te ahumahi mai i PDA i tō rātou pūrongo 2022, he pono ēnei kitenga mā te ao whānui o ngā taupatanga e hiahiatia ana kia manatua ngā here tikanga.

Te Manawaroa ki te Ao Mārama Tōaitanga (UV) me te Aukati i te Mōrearea o te Tā Karuwhā i raro i te Tāraitanga Ao

Kati ngā piri tūturu UV i te 99.9% o ngā nohi UV (280–400 nm), ka aukatia ai te panonitanga o te tae me te pakaru o te matērahi ki ngā taiao waho. Arataki ana ki ngā kōtinga noa e koru ana roto i ngā ono marama, ko ngā matērahi tapiripiri e pupuri ana i te 90% o tō rātou tinihanga tuatahi i muri i te 18 marama ki ngā āhuarangi paratata, kua whakamāoritia e ngā tāwhaiwaenga whakapīpī ASTMG154 (2023).

Te Ingoa o te Matū me te Whaiwāhitanga Ki ngā Mea Kikoikoi

I tētahi rangahau tauira matērahi 2022 i kitea ai ko ngā piri kākāriki hāpai ake i te 250 ngā matū, tae atu ki te 50% hepariki hōhua me ngā karuahi tūmatanui hāpai ake. Kei te pupuri ēnei piri i te here me te kaha o te hanganga i te wā o ngā wā kohikohi 12-marama, e whakaae ana i te kohinga haumaru i ngā waiaroha motuka me ngā matū māra.

Kua Whakapai ake te Ingoa o te Taiao Mātātoko i runga i ngā Whakamahinga Tūmomo me ngā Waho

Ko ngā kiri e huinga ana e whakamarino ana i te pouri, te tūmata o te ao huri noa (UV), me ngā matū, nō reira ka roa ake pea ngā wā e rima te rahinga i ngā taputapu māmā ina tukuna ki ngā tikanga pīroiroi. Whakaarohia ērā tapanga ki ngā taputapu moana e pakaru ana e te ua paraumu ā ia rā, i te wā e rere tonu ana, i ngā tohu ki roto i ngā motuka e noho ana te wera me te hinu. Āe, ko ngā taputapu pakete mātāpae e takoto ana i ngā panonitanga o te wāhi e -30 niha Celsius ki te +60 niha Celsius ka pai hoki ki tēnei atawhai. E ai ki Packaging Digest i te tau e pā nei, ko ngā kamupene e whakamahi ana i ēnei kiri anuanu kaiteka ka iti ake te utu whakakapi umanga 23% ia tau i runga i ngā whakamahinga ahumahi maha. Ka nui ake te penihana i te wā mō ngā kaihanga e mahi ana ki ngā taiao pīroiroi.

Te Ū Āhua ki ngā Matāpuna me ngā Tikanga Tā

Whakaatuia ana e te mātai herehere kākāriki te āhua tino pai ki runga i ngā papamuri rereke me ngā tikanga printi, ka taea ai e ngā kaihanga te whiwhi i ngā hiahia mahi me te ahurea ngāwari.

Te whakawhanuitanga o te papamuri i te herehere (hei tauira, PET, PE, paparua parahi)

Ka herea tika te kākāriki ki te polietilene (PE), polipropilene, poliester (PET), paparua parahi, me ngā matapae penei i te pepa kaua ai te itinga o te here. Tēnei whakawhanuitanga whānui e tautokona ana i te tikanga herehere kotahi mō ngā huinga matapae mīhini. Hei tauira, ko ngā takotoranga parahi-PET e whakamahia ana mō te pupuhi kai e mau ana i te 98% o te kaha arawa i muri i te herehere, e ai ki ngā whakamātau pupuhi maroke i te tau 2023.

Te whakauru ki ngā tikanga printi matihiko, totoiti, me te flexographic

He roa te wā e whakamana ai ngā papa papanga tuku iho, engari mā ēnei kiriata piri kaha, ka taea e ngā whare tā i muri tonu i te tā ki ngā pūnaha UV, offset, me te flexo mamati. Kāore anō kia manukanuka mō te waituhi kua taka, ngā whakaotinga rānei. E kōrero ana mātou mō ngā rerekētanga o te kakara i raro iho i te 8 nekehanga i te nuinga o te wā. Heoi anō, ko te mea nui ko te āhua o te piri o te whakapiri pēhanga ki aua waituhi UV. Ka rere noa iho ki runga i a rātau, kāore e waiho he putea hau i muri. He mea nui tēnei i te wa e whakaputa ana i ngā tapanga me ngā taipitopito pai, e kiia ana te hapa iti katoa ki ngā paerewa kounga.

Ko nga kiriata piri i roto i te papanga kirihou me nga huihuinga maha

Ka hangaia e ngā polymers whakawhiti ngā hononga kaha i waenganui i ngā rauemi rerekē pēnei i ngā kiriata polyester me ngā mata whakakikoruatia whakarewa. I te wā e whakamahia ana i te ahumahi, ka tino pai ake te mahi o ngā paparanga piri e 250 microns te matotoru i ngā kōwhiringa tuku iho e hāngai ana i te waikura. E whakaatu ana ngā whakamātautau ka taea e ēnei whakapiri te whakatutuki i te 35 ōrau te whakapai ake i te kaha o te kiri ka honoa ana te polyethylene ki ngā rauemi PVC. He tino whai hua ngā āhuatanga whakapiri whakarei ake mō te hanga i aua arai maha-paparanga matatini e hiahiatia ana i roto i ngā tono tākai hauora. Ko nga tapanga hokohoko e hiahia ana ki te aukati i te makuku ka whai hua nui mai i tenei hangarau na te mea ka whakaitihia te raru o te wehe o nga papanga i te wa e whakahaere ana me te kawe i nga momo momo tuku.

Ngā tono hira i roto i te Whakakōkī, Ngā Tapanga, me te Hauora

Nga painga o te kiriata whakapiri kaha i roto i te tākai me te tohu ngawari

Ko te tākai ngohengohe e whakawhirinaki ana ki ngā kiriata whakapiri kaha hei pupuri i ngā hua kia roa ake te hou, me te aukati i ngā rerenga me ngā poke e wehi ana tātou katoa. Ko te hoahoa maha-papanga e tino pai ana ki te whakahaere kino me te nui o te pāmahana, he mea nui ina mahi ana ki nga taonga makariri e noho ana i roto i nga whare putunga, ki nga hua ranei e rongoa ana i waho i nga ahuatanga kino o te rangi. I te wā e pā ana ki ngā tapanga, ka mahi ēnei kiriata hei whakangungu mō ngā taipitopito nui pēnei i ngā rā mutunga me ngā tau waehere pae matua e āhei ai te whakahaere i ngā taonga. Kua kite hoki nga kamupene logistics i tētahi mea whakamīharo - tata ki te 84% e mea ana ka iti ake te moni e whakapau ana ki te whakakapi i ngā tapanga kua pakaru mai i te huri ki ngā kōwhiringa papanga. He mea tika, mai i te tiaki i aua mōhiohio tā, ka ora te wā me ngā mamae upoko i te raina.

Te tūranga i roto i te tākai hauora: Te mahi ārai mate me te whakatutukitanga o te ture

Mō ngā rongoā me ngā pūrere hauora, ka waihangahia e ēnei kiriata motuhake he arai kore e tutuki i ngā paerewa ISO 11607-1. Ko te mahi matua ko te aukati i nga huakita kia kore e uru atu, ā, he pai te mahi a rātau ki ngā tikanga whakakorenga noa, tae atu ki te irradiation gamma. I kitea e ngā rangahau tata nei mai i te tau 2023 i te wā e whakamahi ana i ngā kiriata whakairo hauora, he 62% te heke o ngā hapa tākai, arā mō ngā mea pēnei i ngā pūtirotiro kua whakakiia, me ngā kete taputapu tākuta. Ko te mea e tino whai hua ana ko to rātou kaha ki te mahi ki ngā rauemi rite ki a Tyvek, e āwhina ana i ngā kaiwhakanao kia noho i roto i ngā aratohu FDA 21 CFR Wāhanga 11 me ngā whakaritenga EU Annex 1 mō aua kohinga e tino nui ana i roto i ngā taiao hauora.

Te ātete ki ngā tikanga whakakorenga (hei tauira, EtO) i roto i ngā kiriata whakairo-tauine hauora

Ka mau tonu te kakano o ngā papa rongoā ahakoa ka whakawātea ki te whakawātea i te waikura ethylene i te 55 nekehanga Celsius me te 60% te haumākū. He tino hira tēnei āhuatanga ina tae mai ki te tākai i ngā mea e tika ana kia haere ki roto i te tinana. Ka taea e ētahi putanga hou o ēnei rauemi te tu atu ki te kino i puta mai i te tukatuka plasma peroxide me ngā tikanga whakakorenga hau noa. I muri i te haere i te katoa o taua, e taea tonu e ratou te pupuri tahi ki te kaha o te kiri o runga ake i 8 Newtons ia 15 millimeters. Ko te mea e kore e pakaru ēnei rauemi, he tino pai mō te whakarite kia mau tonu ngā kete tātaritanga tiaki kāinga ahakoa te pāngia tonu me ngā rauna maha o te whakakorenga kaha e hiahiatia ana e ngā paerewa hauora o nāianei.
