Ko ngā āhuatanga mahi o ngā rauemi kiriata takai te mea e akiaki tika ana i te whanaketanga mahi o ngā rauemi takai ngāwari hiato. Anei tētahi whakataki poto ki ngā āhuatanga mahi o ētahi rauemi takai e whakamahia whānuitia ana.
1. Ngā rauemi takai e whakamahia whānuitia ana: kiriata PE
Kua whanake ngā rauemi PE hiri-wera mai i ngā kiriata pupuhi papa-kotahi ki ngā kiriata whakapūtā-maha-papa, kia rerekē ai te hoahoa o ngā paparanga o roto, o waenganui, me o waho. Mā te hoahoa ranunga o ngā momo kapia polyethylene rerekē ka taea te whakaputa i ngā pāmahana hiri rerekē, ngā awhe pāmahana hiri-wera rerekē, ngā āhuatanga ārai-hiri rerekē.hKo te kaha o te piripiri, ngā pānga ārai-pūmau, me ētahi atu, hei whakatutuki i ngā whakaritenga motuhake mō te takai hua me ngā rauemi kiriata PE me ngā āhuatanga mahi rerekē.
I ngā tau tata nei, kua whakawhanakehia hoki ngā kiriata polyethylene whakahāngai-rua (BOPE), e whakapai ake ana i te kaha kume o ngā kiriata polyethylene, ā, he kaha ake hoki te hiri-wera.
2. Rauemi Kiriata CPP
Ko ngā rauemi CPP e whakamahia whānuitia ana i roto i te BOPP / CPP mō tēnei hanganga takai mārama ātete-makuku, engari ka taea hoki te hanga i ngā momo hanganga kapia CPP rerekē me ngā āhuatanga mahi rerekē o te kiriata, pērā i te ātete pāmahana iti ake, te ātete ki te tunu pāmahana teitei, te pāmahana hiri iti ake, te kaha poka teitei, te ātete waikura, me ētahi atu āhuatanga mahi o ngā rauemi hiri wera.
RI ngā tau tata nei, kua whakawhanakehia hoki e te umanga he kiriata CPP matte, e whakanui ana i te pānga whakaaturanga tirohanga o ngā putea kiriata CPP paparanga-kotahi.
3. Ngā rauemi kiriata BOPP
Ko te kiriata hiato takai māmā e whakamahia whānuitia ana ko te kiriata māmā BOPP noa me te kiriata matte BOPP, kei reira anō hoki te kiriata hiri wera BOPP (hiri wera taha-kotahi, taha-rua rānei), te kiriata peara BOPP.
Ko te BOPP he mea e kitea ana e tōna kaha kume teitei (he pai mō te tānga maha-tae), he pai rawa atu ōna āhuatanga ārai kohu wai, ā, e whakamahia whānuitia ana i roto i ngā takai mārama ātete-makuku o te mata o te rauemi kua tāia.
Kiriata matte BOPP me te pānga whakapaipai matte rite ki te pepa. Ka taea te whakamahi i te kiriata hiri wera BOPP hei rauemi takai paparanga kotahi, pērā i te takai i te takai o roto o te monamona. Ko te kiriata peara BOPP te nuinga o te wā e whakamahia ana mō te takai aihikirīmi me ngā rauemi paparanga hiri wera, ka taea te penapena i te tānga mangumangu ma, he iti te mātotoru, he kaha hiri 2 ki te 3N/15mm kia ngāwari ai te whakatuwhera i te putea hei tango i ngā mea kei roto.
Hei tāpiri, pērā i te kiriata anti-kohu BOPP, te kiriata laser OPP holographic, te pepa hanga PP, te kiriata BOPP pirau koiora me ētahi atu raupapa kiriata mahi BOPP kua rongonuihia, kua whakamahia hoki i roto i tētahi whānuitanga motuhake.
4. Ngā rauemi tākai e whakamahia whānuitia ana: rauemi kiriata PET
Ko te kiriata māmā PET 12MICRONS noa e whakamahia whānuitia ana i roto i te takai ngāwari hiato, ko te kaha miihini o ana hua takai whakakikorua he nui ake i te BOPP takirua-paparanga hiato (he iti iho i te BOPA takirua-paparanga hiato), ā, ko te kaha arai hāora o te kiriata hiato BOPP/PE (CPP) ka whakaitihia e 20 ki te 30 ngā wā.
He tino pai te ātete wera o ngā rauemi PET, ā, ka taea te hanga kia papatahi te āhua o ngā putea pai. Ka whakamahia hoki te kiriata whakawhāiti wera PET, te kiriata whakawhāiti wera PET matte, te kiriata PET matte, te kiriata polyester ārai-teitei, te kiriata takai PET, te kiriata PET haehae raina me ētahi atu hua mahi.
5. Rauemi tākai noa: kiriata nairona
E whakamahia whānuitia ana te kiriata nairona whakahāngai rua-axial i roto i ngā putea korehau, putea kohua me putea korohū nā te mea he kaha teitei, he ātete ki ngā poka, he ātete ki te pāmahana teitei, ā, he pai ake te ārai hāora.
Ko te nuinga o ngā pēke whakakikoruatia nui te kaha neke atu i te 1.7kg e whakamahi ana i te hanganga BOPA//PE hei ātete pai ki te taka.
He kiriata nairona whakarewa, e whakamahia whānuitia ana i Hapani mō ngā takai kai tio, he ātete pai ki te pāmahana iti, e whakaiti ana i te tere pakaru o te putea i te wā e rokiroki ana, e kawe ana hoki i te pāmahana iti.
6. Rauemi Tākai Noa: Kiriata Whakarewa Paninga Konumohe
Kei roto i te kiriata (pērā i te PET, BOPP, CPP, PE, PVC, me ētahi atu) te paparanga konumohe matotoru i hangaia i runga i te mata o te kiriata, ā, ka nui ake te kaha o te kohu wai, te hāora, me te ārai mārama i runga i te kiriata, ko te mea tino whānuitia te whakamahi i roto i te VMPET me te VMCPP i roto i te tākai ngāwari hiato.
Ko te VMPET mō te whakakirikiri paparanga-toru, ko te VMCPP mō te whakakirikiri paparanga-rua.
Kua whakamahia te hanganga OPP//VMPET//PE hei pēhi i ngā huawhenua, ngā hua pihi i roto i te takai kohua korehau. Kua whakamahia te hanganga PE hei pēhi i ngā huawhenua, ngā hua pihi i roto i te takai kohua korehau, hei whakakore i ngā ngoikoretanga o ngā hua konumohe noa, he ngāwari te heke o te paparanga konumohe, kāore e ātete ki ngā ngoikoretanga o te kohua, kua whakawhanakehia ngā hua VMPET me te momo paninga raro, i mua me muri i te kohua he kaha tihore neke atu i te 1.5N/15mm, ā, te āhua nei kāore te paparanga konumohe e heke, hei whakarei ake i te mahi ārai whānui o te putea.
7. Ngā rauemi takai noa: Pepa konumohe
Ko te pepa konumohe mō te takai ngāwari he 6.5 te nuingaμm, 9 rāneiμm te matotoru 12microns, ko te pepa konumohe he rauemi ārai teitei, ko te urunga wai, ko te urunga hāora, ko te urunga mārama he "0", engari he pono he kōhao iti kei roto i te pepa konumohe, ā, he iti te ātete ki te kōhao iti, he maha ngā āhuatanga kāore e pai te pānga o te takai ārai. Ko te mea nui ki te whakamahi i te pepa konumohe ko te karo i ngā kōhao iti i te wā tukatuka, te takai me te kawe, ā, ka whakaitihia te kaha ārai tuturu. I ngā tau tata nei, kei te kitea te hiahia ki te whakakapi i ngā rauemi pepa konumohe ki ngā rauemi takai ohanga ake i roto i ā rātou wāhi tono tuku iho.
8. Ngā rauemi takai e whakamahia whānuitia ana: ngā kiriata ārai-teitei kua pania
Ko te nuinga he kiriata paninga PVDC (kiriata paninga K), he kiriata paninga PVA (kiriata paninga A).
He tino pai te ātete ki te hāora me te makuku o te PVDC, ā, he tino mārama hoki. Ko te kiriata PVDC pania e whakamahia ana i roto i te kiriata turanga ko te nuinga o te BOPP, BOPET, BOPA, CPP, me ētahi atu, engari ka taea hoki te PE, PVC, cellophane me ētahi atu kiriata. Ko te nuinga o te wā, ko te kiriata KOPP, KPET, KPA te mea e whakamahia ana i roto i te takai ngāwari hiato.
9. Ngā Rauemi Tākai Noa: Ngā Kiriata Ārai Teitei i Whakaputahia Ngātahi
Ko te whakakotahitanga-whakaputa he kirihou rerekē e rua, neke atu rānei, mā roto i ngā whakakotahitanga e rua, neke atu rānei i te rua, ia, kia rewa ai ngā momo kirihou me te whakakirikiri mō te takirua o ngā pane mate, ka whakaritea he kiriata hiato o te tikanga hanga. Ko ngā kiriata hiato ārai whakakotahi-whakaputa he mea hanga mai i te whakakotahitanga o ngā kirihou ārai, ngā kirihou polyolefin me ngā kapia piri o ngā momo rauemi matua e toru, ko ngā kapia ārai ko te nuinga o PA, EVOH, PVDC, me ētahi atu.
Ko ngā mea o runga ake nei he rauemi tākai noa iho, ko te tikanga, ko te iti rawa ko te whakamahi i te paninga kohu waikura, PVC, PS, PEN, pepa, me ētahi atu, me te kapia kotahi e ai ki ngā tikanga tukatuka rerekē, ka taea te whakaputa i ngā whakatakotoranga rerekē mā te whakarerekē i ngā āhuatanga mahi rerekē o te rauemi kiriata. Ko te whakarārangi o ngā kiriata mahi rerekē, mā te whakarārangi maroke, te whakarārangi kore-whakarewa, te whakarārangi extrusion me ētahi atu hangarau hiato hei whakaputa i ngā rauemi tākai hiato ngāwari mahi hei whakatutuki i ngā hiahia o ngā momo rerekē.ngā huatākai.
