Whakarāpopototanga
Ka whakahaerehia e tēnei pepa he rangahau mō te arotautanga mahi me te whakamahinga ongā hiri. I tūhuratia ngā āhuatanga matua e pā ana ki te mahi a ngā hiri mā te tātari i te hanganga, ngā āhuatanga me ngā wāhi tono o te hiri. Ko te arotahi o te rangahau ko te whiriwhiri me te arotau i ngā piripiri, ngā papa me ngā tāpiringa, tae atu ki te whakapai ake i ngā tukanga whakaputa. I whakaatuhia e ngā hua kua tino pai ake te kaha o te piripiri, te ātete ki te huarere taiao me te tiaki taiao o te hiri kua arotauhia. Ka whakaratohia e tēnei rangahau he pūtake ariā me ngā aratohu mahi mō te whakapai ake i te mahi o te piripiri tākai me te whakawhanake i ngā hua hou, he mea nui ki te whakatairanga i te whanaketanga o te umanga tākai.

Kupu Whakataki
Hei rauemi tino nui i roto i te umanga tākai hou, ka pā tika te mahi a te kāpia tākai ki te kounga o te tākai me te haumaru o te kawe waka. Nā te tere o te whanaketanga o te hokohoko ipurangi me ngā whakaritenga taiao e tino kaha haere ana, kua piki ake ngā whakaritenga mō te mahi a te kāpia tākai. Ko te whāinga o tēnei rangahau he whakapai ake i te mahi whānui o ngā hiri mā te arotau i te hanganga me te tukanga whakaputa o ngā hiri kia tutuki ai te hiahia o te mākete.
I ngā tau tata nei, kua whakahaerehia e ngā tohunga o te kāinga me tāwāhi he rangahau whānui mō te kāpia tākai. I ako a Smith me ētahi atu i ngā pānga o ngā momo kāpia ki te mahi a ngā hiri, ko te rōpū a Zhang ia i arotahi ki te whakawhanake i ngā hiri e pai ana ki te taiao. Heoi, kāore anō kia ranea te rangahau mō te arotau whānui o te mahi hiri. Ka tīmata tēnei tuhinga mai i te whiriwhiri rauemi, te arotau hanganga me te whakapai ake i ngā tukanga whakaputa, ā, ka tūhuratia hoki ngā huarahi hei whakapai ake i te mahi a te kāpia tākai.
I. Te hanganga me ngā āhuatanga okāpia tākai
E toru ngā wāhanga matua o te hiri: te piripiri, te papa me te tāpiri. Ko ngā piripiri ngā kai matua e whakatau ana i ngā āhuatanga o ngā hiri, ā, e kitea whānuitia ana i roto i te kiriaku, te rapa me te silicone. Ko te papa he kiriata polypropylene, he pepa rānei, ā, ko tōna matotoru me te maimoatanga mata ka pā ki ngā āhuatanga ā-pūkaha o te rīpene. Kei roto i ngā tāpiri ko ngā mea whakapūmau kirihou, ngā whakakī me ngā antioxidants hei whakapai ake i ngā āhuatanga motuhake o te rīpene.
Ko ngā āhuatanga matua o te hiri ko te piri, te piri tuatahi, te piri pupuri, te ātete ki te huarere taiao me te tiaki taiao. Ko te kaha o te here e whakatau ana i te kaha here i waenga i te rīpene me te piripiri, ā, he tohu nui tēnei mō te mahi a te hiri. Ka pā te matotoru tuatahi ki te kaha piri tuatahi o te rīpene, ko te matotoru o te rīpene e whakaata ana i tōna pumau mō te wā roa. Ko te ātete ki te huarere taiao ko te ātete ki te pāmahana teitei, te ātete ki te pāmahana iti me te ātete ki te makuku. Ko te tiaki taiao e aro ana ki ngā āhuatanga pirau me te kore-paitini o te rīpene ngongo, e tutuki ana i ngā whakaritenga whanaketanga tauwhiro o ngā rauemi takai hou.
II. Ngā wāhi tono o ngā hiri
He whānuitia te whakamahinga o ngā hiri i roto i ngā takai i roto i ngā ahumahi maha. I roto i ngā mahi kawe taonga, ka whakamahia ngā hiri kaha hei pupuri i ngā kātene taumaha, hei whakarite hoki i te haumaru o ngā taonga i roto i te kawe tawhiti. Ko te tikanga o ngā takai hokohoko ipurangi kia pai te matotoru o ngā hiri, kia mau hoki te piri kia taea ai te whakarite me te whakahaere pinepine. I roto i te ao o ngā takai kai, me whakamahi ngā hiri e pai ana ki te taiao hei whakarite i te haumaru me te akuaku o te kai.
I ngā taiao motuhake, he uaua ake te whakamahi i ngā hiri. Hei tauira, i roto i ngā mahi kawe mekameka makariri, me tino ātete te kāpia tākai ki te pāmahana; i roto i ngā taiao rokiroki pāmahana me te makuku teitei, me tino ātete te rīpene ki te wera. Hei tāpiri, ko ētahi ahumahi motuhake pēnei i te hikohiko me te tākai rongoā e whakatakoto ana i ngā whakaritenga teitei ake mō te tiaki hiko me ngā āhuatanga patu huakita o ngā hiri. Ko ēnei hiahia tono kanorau e akiaki ana i te auahatanga me te whanaketanga tonu o te hangarau hiri.
III. Rangahau mō te arotau i te mahi hiri
Hei whakapai ake i te mahi whānui o ngā hiri, ka tirohia e tēnei rangahau ngā āhuatanga e toru o te kōwhiringa rauemi, te arotautanga whakatakotoranga me te tukanga whakaputa. I te kōwhiringa o ngā piri, i whakaritea ngā āhuatanga o ngā rauemi e toru, te kiriaku, te rapa me te silicone, ā, he painga tō te kiriaku i roto i ngā āhuatanga whānui. I arotauhia anō te mahi a te piri kiriaku mā te whakarerekē i te ōwehenga monomer me te taumaha ngota.
Ko te arotautanga o ngā papa e aro nui ana ki te matotoru me te maimoatanga mata. E whakaatu ana te whakamātautau ko te kiriata polypropylene 38μm te matotoru, he mea hanga ki te taha rua, ka tutuki te taurite pai i waenga i te kaha me te utu. Ka whakapai ake te maimoatanga irahiko mata i te kaha o te mata o te papa, ā, ka whakarei ake i te kaha here ki te piripiri. I whakamahia ngā kirihou taiao hei utu mō ngā rauemi tuku iho e ahu mai ana i te hinu, ā, i tāpirihia te nano-SiO2 hei whakapai ake i te ātete ki te wera.
Ko ngā whakapainga i roto i te tukanga whakaputa ko te arotau i te tikanga paninga me te whakahaere i ngā āhuatanga whakamaroke. Mā te whakamahi i te hangarau paninga moroiti-karapa, ka tutuki te paninga ōrite o te piripiri, ā, ka whakahaeretia te matotoru i te 20 ± 2 μm. Kua whakaatuhia e ngā rangahau mō te pāmahana me te wā whakamaroke ko te whakamaroke i te 80 ° C mō te 3 meneti te hua o te mahi pai rawa atu. Nā ēnei arotautanga, i piki ake te kaha o te piripiri o te hiri mā te 30%, i tino whakanuia te ātete ki te huarere taiao, ā, i whakaitihia te tukunga VOC mā te 50%.
IV. NGĀ WHAKATAUNGA
Nā tēnei rangahau i tino whakapai ake i tana mahi whānui mā te arotau i te hanganga me te tukanga whakaputa o te hiri. Kua eke te hiri kua arotauhia ki te taumata ārahi o te umanga i runga i te piri, te ātete ki te huarere taiao me te tiaki taiao. Ka whakaratohia e ngā hua rangahau he turanga ariā me te aratohu mahi mō te whakapai ake i te mahi o ngā hiri me te whakawhanake i ngā hua hou, ā, he mea nui hoki mō te whakatairanga i te ahunga whakamua hangarau me te whanaketanga pumau o te umanga takai. Ka taea e ngā rangahau ā muri ake nei te tūhura i ngā rauemi hou e pai ana ki te taiao me ngā tukanga whakaputa atamai hei whakatutuki i ngā whakaritenga tiaki taiao e kaha haere ana me ngā hiahia takai whaiaro.
