Me pēhea te whiriwhiri i tēnei kōpū PP hei whakamātautau i te wā roa?

He aha ngā take e whakamārama ana i te polypropylene hei matū pai rawa atu mō te kōpū PP?

Ngā rārangi rēsini PP mo ngā kai me ngā whakamānaitanga ā-ture (FDA, EU 10/2011)

Ko ngā raima polypropylene kua whakaaetia mō te whakapā ki ngā kai e tutuki ana i ngā ture a te FDA (21 CFR §177.1520) me ngā paerewa EU (Regulation EC No 10/2011), e whānuitia ana te whakaaetanga puta noa i te ao mō ngā rauemi e pa ana ki ngā hua kai. He tino mārō ngā whakaritenga whakamātautau i whakaritea e ēnei ture ina tae mai ki te mea ka taea te tango i te rauemi. Ko te tikanga, kāore rawa he rerenga o ngā matū kino pēnei i te BPA, phthalates, me ngā konganuku taumaha ki roto i te kai, i ngā inu rānei, ahakoa i muri i te whakapā atu ki ngā wai wera, ngā kiko waikawa, ngā matū ngako rānei. Ko te nuinga o ngā kaiwhakanao e piri ana ki te kirihou PP virgin nā te mea e mōhio ana rātou e tūmanako ana ngā kaihoko i ngā hua haumaru. Ka whakamātauria tēnei mea e ngā taiwhanga tuatoru hei whakapūtā i ōna taumata parakore, me te tirotiro i te nui o te mea ka heke ki te kai i te wā e whakamahia ana. Nā reira, ka taea te whakamahi i ngā kapu werohanga i hangaia mai i tēnei rauemi i ngā wā maha, kāore e āwangawanga mō te takahi i ngā ture haumaru kai.

Te Whakamārama o te Hāngai: Te HDT, te Whakamārama o te Whakamātau i te Hāngai, me te Roa Tūturu (−20°C ki te 110°C)

Ko te Whārangi o te Hāngai o te polypropylene e whānui ana ki runga ake i te 100 degrees Celsius, ā, ko tēnei he whakamārama kia taea ai te whakamātau i te wai pōhutu kāore he rereke o te āhua, ā, he pai hoki hei whakamātau i te whakamātau i te hāngai. Ko ngā kōpae e kōrero nei he kōpae e tū tonu ana mai i te −20 ki te 110 degrees, nō reira kāore ngā rereke o te āhua, kāore hoki ngā rereke o te whakamātau i ngā wā o te mākū me te whakamātau i te hāngai, ā, e taea ana ngā haerenga tāwhai i ngā kōpae kai o ngā rorohiko, ā, e taea ana hoki te whakamātau i ngā wā o te autoclave. I ngā whakamātau hāngai tino pāpā, ko ngā kōpae PP o te kounga teitei e tū tonu ana i ō rātou āhua i ngā whakamātau o ngā tau, ā, he rereke tonu i ngā kōpae PET me PLA. Kāore he whāinga i ngā hōhipera e whakamāhi ana i ēnei kōpae hei kōpae mo ngā tātai, ā, ko ngā rorohiko e whakamāhi ana i ēnei kōpae hei kōpae kai, e mōhio ana kia kāore he rereke o te āhua i te wā o te haere.

Te ārai i ngā matū me ngā mīhini horoi ipu: He hototahi ki ngā kawa horoi hokohoko

He tino pai te tū o ngā kapu werohanga polypropylene ki te nuinga o ngā hua horoi ahumahi kei te mākete i tēnei rā. Ka whakahaerehia e rātau ngā horoi waikawa me ngā taumata pH e eke ana ki te 12 me te kore raruraru, me te mahi pai ki ngā horoi waikawa i raro i te pH 2 me ngā tātai pūmua anō e tino arohaina ana e ngā wharekai. Ko ngā whakamātautau e ai ki ngā paerewa NSF/ANSI 51 me ISO 22000 e whakaatu ana kāore ēnei kapu e kōkō i muri i te whakapā atu ki ngā rongoā waikawa 500 ngā wā, ā, kāore he mate taimaha i whangangahia i ngā awhe pH rerekē. I te wā e whakatakotoria ana ki ngā āhuatanga o te wharekai tūturu, kāore e kitea he tohu o te kākahu i ēnei kapu i muri i te neke atu i te mano horoi i te 82 nekehanga Celsius. Ko te tikanga ko te 40 ōrau te iti ake o ngā whakakapi i ētahi atu kirihou kāore i te kaha, e tino pai ana mō ngā kīhini pukumahi e whakamahia tonu ana ngā taputapu i ia rā, i ia rā.

Ngā Hāngā o te Whakamātautau Āhua e Whakarere ake ai i te Roa o Te Ao o ngā Kōpū PP

Te Whakamātua i te Tāwhai o ngā Pākete: Te Tāwhai i te Mātua o te Tāwhai, te Pākete, me te Whakamātua i ngā Pākete

Ko te tāwhai o ngā pākete i te rārangi o te 1.8 ki te 2.2 mm he tāwhai tino pai i waenganui i te kaha me te whai hua. Ka taea e ēnei kōpū te whakamātua i ngā pākete mai i te 50 ki te 80 kg ia metārā tapawhā i roto i ngā kōpū wāhi hāpai hāpai mō te whakamāhi i te whare, kāore he whakamāhinga. I te wā anō, ka whakamāhi i ākina he iti ake ngā kōpū, ā, he iti ake ngā utu, ā, he pai ake hoki mō te taiao. Ko te whakaputanga ōrite o ngā kōpū hoki e āki ana i ngā pākete kia kore ai ngā pākete kia hanga mai. I ngā whakamātau i te ao whānui, kua kitea ko ēnei pākete āhua kua whakamātua i ngā pākete i te 34% i te whakamātua i ngā pākete kia kore ai ngā pākete i te whakamātua i ngā pākete. I te wā anō, ka mau tonu i āna āhua i muri i ngā tau kōpū o ngā whakamātau hāpai hāpai, ā, he rite tonu ki ngā whakamātau o te FDA. Ko ngā kōpū e whakamāhi ana i te kōpū hāpai hāpai, kāore he whakamāhinga i te hāpai hāpai, ā, he iti tonu ngā kōpū kia whakamāhi ai i te wā katoa o te rā.

Te Whakamārama i te Whakawhitinga o ngā Rūri: Ngā Tāwhai, ngā Rākau ā-Rōpū, me ngā Hākinakina i muri i ngā whakamātautau 5,000+

Ko te ara i tā mātou whakamātautau i ngā āhua he whakamārama i te aha i taea ai te whakarere i ēnei pūrākau iti i ngā wāhi e whakamāhinga ana te hīkoi o ngā kaha. I te wā i tā ngā kaiwhakamahi i ngā rārangi pūpū i ngā tapa o ō rātou hua, kātahi anō ngā kaha o te pakaru i whakawhānuitia mai i te 27%, ā, ko tēnei i whakamāramatia mai i ngā whakamātautau o ASTM D6110. Ā, ko te whakamāmā i ngā kōrner ki te 3 mirimita i te iti haere nei he whakamārama i te aha i taea ai te whakakore i ēnei tapa mātā, ā, ko ēnei te take i tīmata ai ngā pākanga. Ko te mea e rereke ana i te polypropylene ko tēnei āhua o te whakaaro i tāna, ā, he whakamārama i te aha i taea ai te hoki tonu mai i te whakamāmā, ā, he mea nui tēnei i ngā rorohiko o te hauora i te wā i ngā kopa e whakamāhinga ana i ia rā. Ko ngā whakamātautau ā-taumata e whakamārama ana i tēnei, ko ngā kopa kua whakamātautau kē nei ka rereke noa i te 0.2%, i te iti haere nei, i muri i ngā 5,000 whakamāhinga. Ko tēnei he whakamārama i te aha i taea ai te whakamānui i te 400% i te whakamātautau whakamāhinga atu i ngā whakamātautau tātai. Ko te putanga? Kāore ngā hōhipera me ngā rārangi hauāere e hiahia ana ki te whakakapi i ō rātou kopa i ia wā, ā, he whakamārama i te aha i taea ai te whakamāngaro i ngā utu me te whakamāmā i ngā rākau i te wā.

Ngā Tohu o te Kaitaunaki e Whakaatu ana i te Roa o te Wā o te Tāwhai o ngā Kōpae PP

Ko te whai i te whāinga o te whakamātautau i te whakamahinga he mea nui kia taea ai te whakamātautau i te roa o te ora o te hua. Ko ngā kaiwhakamahi pai rawa i tēnei ao e whakamāhi ana i ō rātou whāinga o ngā whakamātautau o ngā pāpā, i te wāhi o ±0.05 mm. Ko tēnei aro ā-mātua i ngā whāinga e tātari ana i ngā raru pērā i ngā wāhi iti o ngā wāhanga, e whakamāngō ana i te whāinga o te whakamātautau, ā, e whakamāngō ana i ngā raru o ngā rerekētanga o ngā āhua e hāngā ana i ngā wāhi o te whāinga i ngā wā kei muri. Ko te whakamāhi i ngā hāngā o te whakamātautau i te wāhi o te ±3°C i te wā e whakamāhi ana i ngā hāngā o te whakamātautau, e whakamāngō ana i te whāinga o te whāinga o ngā kōrero o te whakamātautau, ā, e whakamāngō ana i ngā wāhi kore o roto e whakamāngō ana i te whakamātautau. Ko ngā whare e whakamāhi ana i ngā whakamātautau o ISO 9001 e whakamāhi ana i te 'Statistical Process Control' (SPC) hei whakamāhi i ngā mea pērā i te kaha o te whakamātautau i te wā o te whakamahinga, e whakamāhi ana i te wā o te whakamātautau o ia whakamātautau, ā, e whakamāhi ana i ngā hāngā o te whakamātautau o ngā wāhi. Ko ngā whakamātautau katoa nei e whakamāngō ana i ngā panonitanga iti o ngā āhua i te wā. I muri i te whakamātautau o ngā wāhanga mai i te pāpā, ko ngā whakamātautau katoa e tātari ana i ngā mea e toru kia whakamātautau ai i te wā o te ora o tēnei wāhanga, he rere kē, he rere kē.

• Te ōrite o te nekenga pāpaku (±5% te rerekētanga i te taha o te kōpū)
• Te māmā o te whakamātautau o te kōwhiringa (kāore he whakawhitinga ke i te 0.1 mm e taea ai te whakauru i ngā pākoki)
• Te whakamātautau kore-pākoki , he iti te whāia o te pākoki o te taiao

Ngā whare mahi e whakamahi ana i te whakamātautau ā-kanohi awhina e ngā rorohiko me ngā whakamātautau katoa o te rere, e tātai ana i ngā huringa 500+ o te mahinga kāore i te pakaru, i runga i ngā whakamātautau ā-taumata e ngā kaiwhakamātautau i wāhi kē.

Ngā Tohu Whakamātautau Matua o te Whakamahinga

Te whakamātautau i te ao-ā-ao: Te whakamārama i te whakamāhi anō me te uara o te wā o te ora o tēnei kōpū PP

Ngā whakamātautau i te wāhi: Te tauira o ngā whakamāhi anō i ngā kaiwhakamāhi i ngā hōhipera, i ngā rārangi ā-hāpuka, me ngā rārangi hauārai

He tātai i ngā whakamātau i te ao ōrite hei whakamārama i te take i tēnei rā ka roa ake ngā kapa PP i ēnei wāhi i ērā atu. I ngā kāfeteria, he rite ki te 300 ki te 500 ngā wā e whakamāhinga ana i ēnei kapa i mua i te whakakīkī i a rātou, engari he rerekē ngā āhua mō ngā rārangi hāere mai. Ko te ara i whakamāhinga ai ngā rārangi hāere mai i ā rātou kapa he māmā ake, he whānui ake te whakamāhi, nō reira ka taea te tātai i ngā wā o te whakamāhi i te 700 ki runga ake. Ko ngā rārangi hauora anō hoki ngā whakamātuatanga pai rawa atu, ā, he rite ki te 1,000 ngā wā o te whakamāhi i ēnei kapa, nā te mea ka taea ngā kapa nei te whakamāhi i ngā autoklave me ngā tikanga whakamāhi i te wāhi hauora i te tātai i ngā wā maha. Inā mātua tātai i ēnei āhua katoa ki ngā kapa takitahi, he rerekē tonu ngā āhua. I ngā whakamātau o te Ellen MacArthur Foundation i te tau 2023, i kitea ko ngā kapa PP e whakamāhinga ana e tātai i te 89% te iti ake o te whakamātautau i ngā pākaitanga o te pāpā, i te wā katoa o tā rātou oranga, i ngā kapa kāore i te whakamāhinga anō.
