Me pēhea te whiriwhiri i waenganui i te Kiriata Whakapapa PET me te Kiriata Kākāriki Hau

Kiriata Whakapapa PET vs Kiriata Hau Kākāriki: Te Hāngai Hānganga

Ahakoa ki te manawa molekī he tohu tonu ngā rerekētanga i waenganui i te kiriata whakapapa PET me te kiriata hau kākāriki. Ko te KIRIATA WHAKAPAPA (polyester) kiriata whakapapa he kiriata taketake PET ki te huinga micromita o te paraire e hāngai ana ki te whakaputanga i te āhua paraire me te whakapiripiri i te whakapā, engari he āhua whanui hoki. Ko te kiriata hau kākāriki, i te taha atu, e hāngai ana ki te kiriata paraire kua rerehua kua tūhono ki tētahi turanga polymer ki te hau me te pēhi hei waihanga i tētahi hanganga katoa neke atu te rahi me te whanui.

Nga Tikanga Whakaputanga Kaiwhakapiri vs. Whakapiripiri Mōwea

I te whakaputanga kaiwhakapiri, ko nga ngota karuwha ka whakaputua ki runga i te kiriata PET ki roto i te kāmera hau parurenga, e hanga ana i te kiriata whakamarō o te iti ake i te 0.05 microns te tino. Kei te tiaki tēnei tikanga i te 99% o te whiriwiri o te pūtake, ā, ka taea hoki e ia te here i te 99.5% o te tuku aho. Ko te whakapiripiri mōwea, i te taha ke, e whakapiripiri ana i te kiri karuwha kua huihui kē (he nui ake te 6–20 micrometers te tino) ki ētahi atu rawa, pērā i ngā polymer pērā i te polyethylene, ki te kāpua.

Nga putanga hanganga matua:

• Whakamahitanga o ngā rauropi : Ko te whakaputanga kaiwhakapiri e whakamahi ana i te 99% iti ake te karuwha i ngā kiriata kiriata kaiwhakapiri (Pūrongo Whakamahinga Rawa 2023).
• Te Kotahitanga O Te Takitahi : Ko te whakapiripiri mōwea e hanga ana i ngā hononga takitahi kaha ake (12–18 N/15mm te pakaru pakaru) engari ka piki ake te pātata.
• Te Kotahitanga O Te Otinga : Ko te whakaputanga kaiwhakapiri e eke ana i te <5nm te kiriata o te otinga, e iti ake ana i te 40% o ngā ngoikera ki te whakaritea ki ngā kiriata kua piripiria.

Ko ngā rerekētanga o ngā tikanga e whai pānga nui ana ki te mahi i te whakakaha ki te wai, te whakapāwhara, me te utu—ngā āhuatanga ka tūhonoa i ngā wāhanga e whai muri ana.

Te Whakataetae ake i ngā Āhuatanga Whakarā: Te Whakamaru i te Hauwhero me te Hau

Te Whakaururanga Whakataurite i te Hauwhero Hauwhero

Na te tōaitanga o ngā takotoranga hiriwa hiriwa hiriwa, ahakoa kāore i te rite te nui o te wā i te kōrero mo ngā kiriata paripari wera, he iti ake ngā kiriata hiriwa i te whakamaru i te wai. Ko ngā whakamātau ASTM E96 e whakaatu ana ko ngā kiriata hiriwa he whakaururanga hauwhero hauwhero e iti ake i te 0.5 g/m²/rā, i te wā e 1.0-2.5 g/m²/rā hoki ngā kiriata paripari wera nā ngā rāranga iti ki roto i te kiriata kōtaha. He mea matua tēnei rerekētanga ki te tukanga parakore i ngā wā tūmata e 80% RH ki te pā ki ngā hua pāpaku (rongoā, kai pātata), ka hiahiatia ai te whakamaru pai ake ki ngā kiriata hiriwa.

Te Whakaroa i te Oxi i roto i te Kaitakotoranga Kai

Ko te mahi o te kaitiaki hau e whakatau ana i te wā kia noho ai ngā kai e āhua ngoikera ana, pērā i ngā hinu me ngā kai tātou kē. (Ko te rāpua hōu, kāore he kuhu, e āhua māmī ana ki te rahi o te nekeneke mā te kaiwhakarite i te kaitiaki hau.) Ko ngā tāmata o ngā peera hou e pā atu ana ki te whakapai ake i te hau, nō te mea ka pakaru te kōpiko. I tētahi whakamātau i ngā kaitiaki hou i te tau 2024 kua kitea ko ngā kiriatau e hōu ana i te wāhi e iti ake ai te rere o te hau i te 95% tēnā i ngā taputapu kāore anō kia kiriatau, ā, i te mea ka whakaroa ake i te rereke o ngā kai e kaha ana ki te hinu.
