He Aratohu Whānui ki ngā Rauemi me ngā Whakamahinga o te Pēke Korehau mō ngā Mīhini Tākai Korehau DJVAC

Tirohanga Whānui mō ngā Rauemi Tākai me te Pēke Korehau

Ka tangohia e ngā mīhini takai korehau (momo rūma, momo momi rānei) te hau i roto i te pēke, i te rūma rānei o te hua, kātahi ka hiritia te pēke hei aukati i ngā hau o waho. Ka roa ake te ora o te hua mā te whakaiti i te pānga ki te hāora me te aukati i ngā huakita pirau..Hei whakatutuki i tēnei, me whakakotahi ngā pēke korehau i ngā āhuatanga ārai kaha me te pakari ā-mīhini me te hiri wera pono..Ko ngā pēke korehau noa he kirihou paparanga maha, he mea whiriwhiri mō ia pēke mō ngā āhuatanga pēnei i te ārai hāora/makuku, te ātete wera, te mārama me te pakari o te poka..

Pēke Korehau Nailoni/PE (PA/PE)

•Te Hanganga me ngā Āhuatanga:Ko ngā putea PA/PE he paparanga o waho o te nairona (polyamide) kua whakakikoruatia ki te paparanga hiri o roto o te polyethylene..Ka whakarato te paparanga nairona i te ātete nui ki te poka me te pakū, me te ārai nui ki te hāora/kakara, ā, ka whakarite te paparanga PE i ngā hiri wera kaha ahakoa i te pāmahana iti..Ki te whakatauritea ki te kiriata PE noa, he nui ake te ārai hāora me te kakara o ngā paparanga PA/PE, ā, he pai ake te ātete ki ngā poka..Ka mau tonu hoki te pumau o ngā āhuatanga i roto i ngā tukanga hukapapa hōhonu me te hanga wera, ā, ka tu atu ki te wera ngawari i te wā e hiritia ana.

•Ngā tono:He whānuitia te whakamahinga o ngā putea PA/PE mō ngā mīti hou me ngā mīti tio (pīhi kau, poaka, heihei, kaimoana) nā te mea ka ātete te nairona ki ngā taha wheua me ngā wahi koi..Ka pupuri ēnei putea i te tae me te reka o te mīti i te wā e rongoatia ana i roto i te makariri mō te wā roa. He tino pai hoki mō te tiihi me ngā hua kai reka, e pupuri ana i te reka me te kakano mā te whakaiti i te urunga o te hāora. Ka mahi anō hoki te kiriata pakari mō te takai korehau i ngā mīti tukatuka, ngā pâté, ngā kai kua oti te taka. Ka taea hoki te whakahaere i ngā wai-haurua me ngā ranu ki roto i ngā putea PA/PE; ka ārai te paparanga hiri kaha i ngā turuturu, ā, ka pupuri i ngā kakara..He poto, he pai ngā putea PA/PE mō ngā kai he āhua rerekē, he mārō rānei ngā taha (he wheua, he maramara mīti) e hiahia ana kia rongoatia ki te pouaka whakamātao, kia tio rānei mō te wā roa.

•Ngā Whakamahinga Kē:Haunga te kai, ka whakamahia ngā papa PA/PE mō ngā takai hauora me ngā wāhanga ahumahi. Ka taea te whakahoromata me te hiri i te kiriata ārai-teitei me te pakari mō ngā kete hauora, engari i roto i ngā takai hiko ka whakahaere i te makuku me te tāpiri i te kaha ā-ringa..Ka taea te tāpiri i ngā paparanga ārai-pūmau, ārai rānei mō ngā papa hiko, mō ngā taputapu rānei. Hei whakarāpopototanga, he kiriata mahi ngā putea PA/PE – he ārai teitei, he kaha poka – e hototahi ana ki te nuinga o ngā hiri korehau (rūma, o waho rānei), ā, he mea pai rawa atu ēnei mō ngā takai korehau whānui.
