He rauemi tākai watea, he rauemi ohanga hoki te ngongo, ā, he mea whakamahi whānuitia i roto i te ao o ngā matū o ia rā, ā, he tino rongonui. Ehara i te mea ka taea e te ngongo pai te tiaki i ngā ihirangi anake, engari ka whakapai ake hoki i te taumata hua, ā, ka riro mai i a ia he maha atu o ngā kaihoko mō ngā kamupene matū o ia rā. Nō reira, mō ngā kamupene matū o ia rā, me pēhea te whiriwhiri i te kounga teitei?ngā ngongo kirihoue tika ana mō ā rātou hua? Ka whakamāramahia i raro nei ētahi āhuatanga nui.
Ko te whiriwhiri me te kounga o ngā rauemi te mea nui hei whakarite i te kounga o ngā ngongo, ka pā tika ki te tukatuka me te whakamahinga whakamutunga o ngā ngongo. Ko ngā rauemi o ngā ngongo kirihou ko te polyethylene (mō te tinana ngongo me te pane ngongo), te polypropylene (te taupoki ngongo), te masterbatch, te kapia ārai, te waituhi tā, te wanihi, me ētahi atu. Nō reira, ko te whiriwhiri i tētahi rauemi ka pā tika ki te kounga o te ngongo. Heoi, ko te whiriwhiri i ngā rauemi ka whakawhirinaki anō hoki ki ngā āhuatanga pēnei i ngā whakaritenga akuaku, ngā āhuatanga ārai (ngā whakaritenga mō te hāora, te mamaoa wai, te tiaki kakara, me ētahi atu), me te ātete matū.
Te Kōwhiringa o ngā Paipa: Tuatahi, me tutuki ngā rauemi e whakamahia ana i ngā paerewa akuaku e tika ana, ā, me whakahaere ngā matū kino pēnei i ngā konganuku taumaha me ngā matū kanapa i roto i te awhe kua whakaritea. Hei tauira, mō ngā ngongo e kaweake ana ki te Hononga o Amerika, me tutuki te polyethylene (PE) me te polypropylene (PP) e whakamahia ana i te paerewa 21CFR117.1520 a te US Food and Drug Administration (FDA).
Ngā Āhuatanga Ārai o ngā Rauemi: Mena he hua tino pāngia e te hāora ngā ihirangi o ngā kamupene matū o ia rā (pēnei i ētahi mea whakapaipai mā), he tino pūngāwerewere rānei te kakara (pēnei i ngā hinu kakara, ētahi hinu rānei, waikawa, tote me ētahi atu matū waikura), me whakamahi ngā ngongo e rima-paparanga e whakapūtā ana i tēnei wā. Nā te mea ko te urunga hāora o te ngongo e rima-paparanga e whakapūtā ana (polyethylene/reini piri/EVOH/reini piri/polyethylene) he 0.2-1.2 waeine, ko te urunga hāora o te ngongo polyethylene paparanga kotahi noa he 150-300 waeine. I roto i tētahi wā, he maha ngā wā ka iti ake te tere o te whakaheke taumaha o te ngongo e rua-paparanga kei roto te etanoru i tērā o te ngongo kotahi-paparanga. Hei tāpiri, he copolymer waipiro ethylene-vinyl te EVOH me ngā āhuatanga ārai me te pupuri kakara pai rawa atu (ko te matotoru o te 15-20 microns te mea tino pai).
Te pakari o ngā rauemi: He rerekē ngā whakaritenga a ngā kamupene matū o ia rā mō te pakari o ngā ngongo, nō reira me pēhea te whiwhi i te pakari e hiahiatia ana? Ko te polyethylene e whakamahia whānuitia ana i roto i ngā ngongo ko te polyethylene iti-kiato, te polyethylene teitei-kiato, me te polyethylene iti-kiato raina. I roto i ēnei, he pai ake te pakari o te polyethylene teitei-kiato i te polyethylene iti-kiato, nō reira ka taea te whakatutuki i te pakari e hiahiatia ana mā te whakarerekē i te ōwehenga o te polyethylene teitei-kiato/polyethylene iti-kiato.
Ātete matū o ngā rauemi: He pai ake te ātete matū o te polyethylene kiato-teitei i te polyethylene kiato-iti.
Te ātete ki te huarere: Hei whakahaere i te mahi poto, te mahi roa rānei o te ngongo, me whai whakaaro ki ngā āhuatanga pēnei i te āhua, te ātete ki te pēhanga/te maturuturunga iho, te kaha o te hiri, te ātete ki te pakaru i te ahotea taiao (te uara ESCR), te kakara me te ngaronga o ngā matū hohe.
Te Kōwhiringa o te Masterbatch: He mea nui te Masterbatch ki te whakahaere kounga o te ngongo. Nō reira, i te wā e whiriwhiri ana i te Masterbatch, me whakaaro te kamupene kaiwhakamahi mēnā he pai te horapa, te pumau tātari me te pāmahana, te ātete huarere me te ātete hua. I roto i ēnei, he mea nui te ātete hua o te Masterbatch i te wā e whakamahia ana te ngongo. Mena kāore te Masterbatch e hototahi ki te hua, ka heke te tae o te Masterbatch ki te hua, ā, he tino kino ngā hua. Nō reira, me whakamātautau ngā kamupene matū o ia rā i te pumau o ngā hua me ngā ngongo hou (ngā whakamātautau tere i raro i ngā tikanga kua tohua).
Ngā momo wanihi me ō rātou āhuatanga: Ka wehea te wanihi e whakamahia ana i roto i te ngongo ki te momo UV me te momo whakamaroke wera, ā, ka taea te wehewehe ki te mata kanapa me te mata matte i runga i te āhua. Ehara i te mea ka whakaratohia e te wanihi he pānga tirohanga ataahua anake, engari ka tiakina hoki ngā ihirangi me te pānga ki te aukati i te hāora, te mamaoa wai me te kakara. I te nuinga o te wā, he pai te piri o te wanihi whakamaroke wera ki te tā wera me te tā mata hiraka i muri mai, engari he pai ake te kanapa o te wanihi UV. Ka taea e ngā kamupene matū o ia rā te whiriwhiri i te wanihi tika kia rite ki ngā āhuatanga o ā rātou hua. Hei tāpiri, me pai te piri o te wanihi kua rongoatia, he mata maeneene kāore he poka, he ātete ki te takai, he ātete ki te kakahu, he ātete ki te waikura, ā, kāore he tae i te wā e rongoa ana.
Ngā Whakaritenga mō te tinana ngongo/te pane ngongo: 1. Me maeneene te mata o te tinana ngongo, kāore he rārangi, he karawarawa, he totoro, he whakaheke rānei. Me tika te tinana ngongo, kaua e piko. Me ōrite te matotoru o te pakitara ngongo. Me noho te matotoru o te pakitara ngongo, te roa o te ngongo, me ngā āheinga whānui ki roto i te awhe kua tohua;
2. Me hono pūmau te pane o te ngongo me te tinana o te ngongo, me ātaahua, me rite te whānui. Kaua te pane o te ngongo e piko i muri i te hononga; 3. Me ōrite te pane o te ngongo me te taupoki o te ngongo, me maeneene te whakaweto me te whakaweto, ā, kaua e paheke i roto i te awhe taipana kua tohua, ā, kaua hoki e turuturu te wai, te hau rānei i waenganui i te ngongo me te taupoki;
Ngā whakaritenga tā: Ko te tukatuka ngongo he tikanga tānga ā-tuhi (OFFSET), ā, ko te nuinga o te waituhi e whakamahia ana he mea whakamaroke ki te UV, e hiahia ana kia kaha te piri me te ātete ki te hurihanga. Me noho te tae tā ki roto i te whānuitanga hohonu kua tohua, me tika te tūranga tānga, me noho te peka ki roto i te 0.2mm, ā, me oti, me mārama hoki te momotuhi.
Ngā Whakaritenga mō ngā Taupoki Kirihou: Ko ngā taupoki kirihou he mea hanga i te hanga werohanga polypropylene (PP). Ko ngā taupoki kirihou kounga teitei me kore he rārangi whakaheke me te kanapa e kitea ana, he rārangi pokepoke maeneene, he ine tika, ā, he maeneene te uru ki te pane o te ngongo. Kaua e puta he kino hanganga pērā i te pakarukaru, te pakaru rānei i te wā e whakamahia ana. Hei tauira, ina kei roto i te awhe te kaha whakatuwheratanga, me kaha te taupoki hurihuri ki te tu atu i te neke atu i te 300 takahanga me te kore e whati.
Ki taku whakaaro, mai i ngā āhuatanga o runga ake nei, me kaha te nuinga o ngā kamupene matū o ia rā ki te whiriwhiri i ngā hua tākai ngongo kounga teitei.
