BOPP (OPP)——he kiriata polypropylene e anga ana ki te taha rua, he kiriata i hangaia mai i te polypropylene hei rauemi mata matua, ā, ka totorohia ki te taha rua mā te tikanga kiriata papatahi. He kaha kume teitei, he pakari teitei, he mārama hoki. He pai, he kanapa pai, he iti te mahi pūmau, he pai te mahi tā me te piri paninga, he pai ngā āhuatanga kohu wai me te ārai, nō reira he whānui te whakamahinga i roto i ngā ahumahi takai.
PE - Polyethylene. He kapia kirihou wera tēnei i whiwhihia mā te whakakotahitanga o te ethylene. I roto i te ahumahi, kei roto hoki ngā copolymer o te ethylene me te iti o ngā α-olefin. Kāore he kakara o te polyethylene, kāore he paitini, he rite te āhua ki te ware pi, he ātete pai ki te pāmahana iti (ka taea e te pāmahana mahi iti rawa te eke ki te -100~-70°C), he pai te pumau matū, ā, ka taea te tu atu ki te nuinga o te waikawa me te kawakore (kāore e ātete ki te waikura) o te waikawa). Kāore e rewa i roto i ngā whakarewa noa i te pāmahana rūma, he iti te mimiti wai, he pai te whakamarumaru hiko.
CPP—arā, ko te kiriata polypropylene whakarewa, e mōhiotia ana ko te kiriata polypropylene kāore i totoro, ka taea te wehewehe ki te kiriata CPP whānui (CPP Whānui, GCPP mō te poto) me te kiriata CPP pania-konumohe (Metalize CPP, MCPP mō te poto) e ai ki ngā whakamahinga rerekē me te kiriata CPP tunu kai (Retort CPP, RCPP mō te poto), me ētahi atu.
VMPET - e pā ana ki te kiriata polyester konumohe. Ka tāpirihia ki te kiriata tiaki i runga i te takai o ngā kai maroke me ngā kai pupuhi pērā i ngā pihikete me te takai o waho o ētahi rongoā me ngā mea whakapaipai.
He rite ngā āhuatanga o te kiriata konumohe ki te kiriata kirihou, me ngā āhuatanga o te konganuku. Ko te mahi a te whakakikorua konumohe i runga i te mata o te kiriata he whakamarumaru me te ārai i te hihi ultraviolet, e kore e whakaroa noa i te roa o te oranga o ngā mea o roto, engari ka whakapai ake hoki i te kanapa o te kiriata. , he whānui te whakamahinga o te kiriata konumohe i roto i ngā takai hiato. I tēnei wā, e whakamahia ana i roto i ngā takai o ngā kai maroke me ngā kai pupuhi pērā i ngā pihikete, tae atu ki ngā takai o waho o ētahi rongoā me ngā mea whakapaipai.
PET - e mōhiotia ana ko te kiriata polyester ātete pāmahana teitei. He tino pai ōna āhuatanga ā-tinana, āhuatanga matū me te pumau o ngā āhuatanga, te mārama, me te hangarua, ā, ka taea te whakamahi whānui i roto i te tuhi aukume, ngā rauemi whakaahua-ā-ahua, ngā hikohiko, te whakamarumaru hiko, ngā kiriata ahumahi, te whakapaipai takai, te tiaki mata, ngā whakaata whatu Tiaki mata me ētahi atu mara. Tauira kiriata polyester ātete pāmahana teitei: FBDW (pango matte taha kotahi) FBSW (pango matte taha rua) Ngā whakatakotoranga kiriata polyester ātete pāmahana teitei Te matotoru Te whānui o te diameter o te roera Te diameter matua 38μm~250μm 500~1080mm 300mm~650mm 76mm(3〞), 152mm (6〞) Kia mahara: Ka taea te whakaputa i ngā whakatakotoranga whānui kia rite ki ngā hiahia tūturu. Ko te roa noa o te roera kiriata he 3000m, he 6000 rānei te rite ki te 25μm.
PE-LLD—He Polyethylene Matotoru Iti Rārangi (LLDPE), he matūriki mā te miraka, kāore he paitini, kāore he reka, kāore he kakara, he mātotoru 0.918~0.935g/cm3. Ki te whakatauritea ki te LDPE, he teitei ake tōna pāmahana whakangawari me te pāmahana rewa, ā, he pai hoki tōna kaha, he pakari, he pakari, he ātete ki te wera, me te ātete ki te makariri. He pai hoki tōna ātete ki te pakaru i te ahotea taiao, te kaha pānga, me te roa. He kaha haehae me ētahi atu āhuatanga, ā, ka taea te ātete ki ngā waikawa, ki ngā kawakore, ki ngā whakarewa waro, me ētahi atu, ā, he whānuitia te whakamahinga i roto i ngā mara o te ahumahi, te ahuwhenua, te rongoā, te akuaku me ngā mea e hiahiatia ana i ia rā. Ko te kapia polyethylene matotoru iti rārangi (LLDPE), e mōhiotia ana ko te polyethylene o te whakatupuranga tuatoru, he kaha kume, he kaha haehae, he ātete ki te pakaru i te ahotea taiao, he ātete ki te pāmahana iti, ā, he tino pai ake te ātete ki te wera me te wero.
BOPA (NYLON) - te whakarāpopototanga reo Ingarihi mō te kiriata polyamide (nylon) Biaxially oriented. He rauemi nui te kiriata nylon Biaxially oriented (BOPA) mō te hanga i ngā momo rauemi takai hiato, ā, kua noho ko ia te tuatoru o ngā rauemi takai nui rawa atu i muri i ngā kiriata BOPP me BOPET.
Kiriata nairona (e kiia ana ko PA) He kiriata tino pakari te kiriata nairona, he mārama pai, he kanapa pai, he kaha te kume me te kaha kume, ā, he pai te ātete ki te wera, ki te makariri me te hinu. He pai te ātete ki ngā whakarewa waro, he ātete ki te pakū, he ātete ki te wero, ā, he ngawari, he pai te ātete ki te hāora, engari he ngoikore te ārai ki te kohu wai, he nui te mimiti makuku, he uruhanga makuku, he ngoikore te hiri wera, he pai mō te tākai i ngā taonga pakari, pērā i te kai hinuhinu, ngā hua mīti, ngā kai parai, ngā kai kua takai korehau, ngā kai kōhua, me ētahi atu.
Ka hangaia e ā mātou kiriata me ā mātou paparanga whakamātao hei tiaki i tō hua mai i ngā kino ina tākaihia. He maha ngā momo rauemi tākai tae atu ki te polyethylene, te polyester, te nairona, me ētahi atu kua whakarārangihia i raro nei e whakamahia ana hei hanga i tēnei ārai paparanga.
Ngā Pātai Auau
Pātai 1: Me pēhea te whiriwhiri i ngā rauemi mō te kai tio?
Whakautu: Ko te takai kirihou ngāwari e whakamahia ana i roto i te ao o te kai tio e wehea ana kia toru ngā wāhanga matua: ko te wāhanga tuatahi ko ngā putea paparanga kotahi, pērā i ngā putea PE, he iti te pānga ārai, ā, e whakamahia whānuitia ana mō te takai huawhenua, me ētahi atu; ko te wāhanga tuarua ko ngā putea kirihou ngāwari hiato, pērā i ngā putea OPP //PE (kounga iti), NYLON//PE (he pai ake te PA//PE), me ētahi atu, he pai ngā āhuatanga ātete makuku, ātete makariri, me te ātete poka; ko te wāhanga tuatoru ko ngā putea kirihou ngohengohe maha-paparanga, e whakakotahi ana i ngā rauemi mata me ngā mahi rerekē, Hei tauira, ko te PA, PE, PP, PET, me ētahi atu ka rewahia, ka whakaputahia motuhaketia, ā, ka whakakotahihia ki te pane mate katoa mā te whakakoi me te whakamatao. Ko te momo tuarua he mea whakamahi whānuitia i tēnei wā.
Pātai 2: He aha te momo rauemi e pai ake ana mō ngā hua pihikete?
Whakautu: Ko te OPP/CPP, OPP/VMCPP rānei e whakamahia whānuitia ana mō ngā pihikete, ā, ka taea te whakamahi i te KOP/CPP, KOP/VMCPP rānei hei pupuri i te reka.
Pātai 3: Me hiahia au ki tētahi kiriata hiato mārama me ngā āhuatanga ārai pai ake, nō reira ko tēhea te mea he pai ake ngā āhuatanga ārai, te paninga BOPP/CPP k, te PET/CPP rānei?
Whakautu: He pai ngā āhuatanga ārai o te paninga K, engari kāore te māramatanga i te rite te pai ki te PET/CPP.
