I raro i ngā pēhanga rua o te "whakapūmau hiko" me te "whakamāmā" i ēnei rā'I roto i te umanga motuka o nāianei, ko ia karamu e penapenahia ana ka hua mai he whānuitanga whānui me te whakaiti i te whakapaunga pūngao. Ahakoa he nui te aro ki ngā wāhanga nunui pēnei i ngā hanganga tinana me ngā kete pākahiko, kei te huri haere tetahi wāhanga iti engari he mea nui.—te anga nohoanga waka.
Ko ngā anga nohoanga tuku iho he mea hanga ki te maitai tā me te maitai whakarewa. Ahakoa e tutuki ana i ngā whakaritenga kaha, he taumaha, ā, he iti noa te mana hoahoa e tukuna ana. I te tere o te whanaketanga o ngā kirihou hangarau, kei te tere te whakakapi a te polypropylene roa kua whakapakarihia ki te muka karāhe (LGF/PP) i te konganuku hei rauemi pai mō ngā anga nohoanga o te whakatupuranga e whai ake nei.
He aha te muka karāhe roa PP?
He rerekē ki ngā rauemi whakakaha muka karāhe poto tuku iho (ko te roa o te muka he iti iho i te 1 mm), ko te polypropylene whakakaha muka karāhe roa e pā ana ki tētahi rauemi whakakotahi kua whakarerekētia kei roto ngā muka karāhe he 10 te roa.–25 mm. Ka tukuna e tēnei hanganga ahurei he pikinga kounga teitei i roto i te mahi rauemi:
Whatunga muka toru-ahu: I te wā e hangaia ana te whakakoi, ka honoa ngā muka karāhe roa ki roto i te anga polymer, ka hanga he angaanga toru-ahu. Ahakoa ka ngohengohe te rauemi turanga i ngā pāmahana teitei, ka āwhina te whatunga muka ki te pupuri i tōna āhua.—he āhuatanga e mōhiotia ana ko te "pānga angaanga muka".
Te roa o te muka toenga teitei: Ko te roa o te muka e toe ana i te wāhanga kua oti he nui ake i te roa o ngā rauemi tuku iho. Koinei te mea ngaro matua o tōna pakari teitei.
He aha i tino pai ai mō ngā anga nohoanga?
Mō ngā kaihanga motuka, ehara i te mea ko te whakamarie anake te kaupapa o ngā nohoanga—he wāhanga haumaru ēnei. Mēnā ka tukinga, me tu atu te anga nohoanga i ngā kaha pānga nui, me te pupuri tonu i te hanganga pai. Ka whakatau pai a LGF/PP i te pakanga i waenga i te pakari me te pakari i roto i ngā kirihou hangarau:
He kaha teitei me te ātete pānga: He tino pai te kaha kume me te nekehanga piko o te LGF/PP, me te ātete pānga3–E 5 ngā wā teitei ake i tērā o ngā rauemi whakakaha muka karāhe poto tuku iho. I roto i te tukinga, ka mimitihia e ia te kaha nui mā te whakarerekētanga me te kore e pakarukaru, ā, ka tiakina ngā kainoho.
Ātete ngoki pai rawa atu: Ko ngā nohoanga he wāhanga e mau ana i te kawenga ka pāngia e te taumahatanga roa. Ahakoa ka rerekē te āhua o ngā kirihou tuku iho i raro i te kawenga pumau, ka mau tonu te pumau o ngā āhuatanga o te LGF/PP ahakoa i te 100°C mō ngā wā roa, ātete ana ki te whakarerekētanga tuturu.
He whakaiti taumaha nui: Ki te whakatauritea ki ngā hanganga maitai tuku iho, ka eke ngā anga nohoanga LGF/PP ki te 20–He whakaiti taumaha 30%, e āwhina tika ana ki te whakaiti i te whakapaunga wahie, ki te whakawhānui rānei i te whānuitanga o te EV.
Te herekoretanga hoahoa: Ka taea e te LGF/PP te whakauru i ngā wāhanga whakarewa maha ki roto i te wāhanga kotahi, matatini i werohia-whakakikoruatia, ka whakangawari ake i te huihuinga me te whakaiti i ngā utu taputapu (tata ki te 20% o ērā mō ngā mate tā whakarewa).
Ngā Taupānga o te Ao Tūturu
Ehara tēnei rauemi i te ariā taiwhanga—kua whakamanahia kētia i roto i ngā waka i hangaia papatipu.
1Ka whakamahia e tōna anga nohoanga he hiato kirihou whakarewa kua whakakahangia ki te muka karāhe tonu, e tino pakari ai, ā, e tata ana ki te 800 karamu te taumaha e penapenahia ana ki te whakaritea ki te hanganga maitai.
2Ka whakamahia e tōna waeine tatau o mua me ngā wāhanga nohoanga te LGF/PP hei whakatutuki i te whakaurunga mahi teitei, me te mahi ngoki iti kua whakaatuhia i ngā pāmahana teitei.
Tirohanga Hangarau
I te hōhonu haere o te ia o te "whakakapi i te konganuku ki te kirihou", kāore te LGF/PP e herea noa ki ngā waka miihini tahunga ā-roto. I roto i te wāhanga waka hiko hou, he mea nui ia kirokaramu o te whakaiti taumaha. Mā ngā tukanga whakakoi werohanga kua arotauhia (hei tauira, te whakahaere i ngā pāmahana rewa i waenga i te 190°C me te 250°C), ka taea te whakanui ake i te kaha pānga o te rauemi mā te neke atu i te 50%.
Hei tāpiritanga, ko ngā whanaketanga o ngā hangarau iti-kakara me te iti-VOC kei te hanga i te LGF/PP kia pai ake te taiao, kia tutuki ai hoki ngā paerewa kounga hau o roto i te kāpini.
Whakamutunga
Kei te huri haere ngā anga nohoanga motuka mai i ngā anga maitai ki ngā pūmua whakarewa. Nā te whakakotahitanga tino pai o te kaha teitei, te pakari teitei, me te taumaha iti, kei te noho te polypropylene roa kua whakapakarihia ki te muka karāhe hei rauemi whiriwhiri mō te hoahoa nohoanga o te whakatupuranga e whai ake nei. Ehara i te mea ka iti ake ngā utu whakahaere mō ngā kaihoko engari ka tukuna hoki ki ngā kaihangarau he huarahi hou mō te whakaaro hou ki ngā wāhi o roto o te waka. I roto i te whakataetae ki te whakamama, ko te LGF/PP tētahi o ngā mea kei mua.
