2、 Hoʻohana kikoʻī o ka membrane PVDC composite ma Kina:
Ua hoʻomaka ʻo Kina i ka hoʻohana pono ʻana o ka resin PVDC mai ka hoʻomaka ʻana o 1980s.ʻO ka mea mua, ʻo ka hānau ʻana o ka sausage ham i hoʻokomo i ke kiʻi PVDC i Kina.A laila ua uhaki nā hui Kina i ka poloka o ʻAmelika Hui Pū ʻIa a me Iapana ma kēia ʻenehana a hoʻolauna i ka ʻenehana hana a me nā mea hana o ka kiʻiʻoniʻoni PVDC.Me ka ulu mau ʻana o ka hoʻokele waiwai o Kina a me ka hoʻomaikaʻi ʻana i ka waiwai o nā kānaka a me ke ola moʻomeheu, ke piʻi nei ke kiʻekiʻe o ka noi no ka ʻeke.Hoʻohana nui ʻia ka hoʻohana ʻana i nā mea hoʻohana ma nā ʻano āpau o ka hoʻokele waiwai a me ke ola kanaka.He alakaʻi ʻo PVDC i ka hoʻokōpale pale kiʻekiʻeʻO ka maikaʻi o ke kumu kūʻai a me ka makū hilinaʻi, ka oxygen a me ka pale ʻala.
No ka mea ʻoi aku ka ʻike o ka poʻe āpau i ke kiʻiʻoniʻoni casing PVDC, eia mākou e nānā i nā ʻano loea a me nā waiwai o ka kiʻiʻoniʻoni PVDC composite.Hoʻopili ke kiʻi ʻoniʻoni i nā hemahema o kēlā me kēia mea, hāʻawi i ka pāʻani piha i kāna hana maikaʻi loa, a he mau hiʻohiʻona i loaʻa ʻole i kahi mea hoʻokahi.Nā ʻano hana maʻamau o PVDC:
ʻO ka uhi ʻana, maloʻo, solvent-free, wela hoʻoheheʻe, co-extrusion, a me nā mea ʻē aʻe.
1) PVDC uhi kiʻiʻoniʻoni
Hoʻopili ʻia ka PVDC latex coating ma ka ʻili o ka substrate (OPP, PA, PE, PET, etc.) e hana i kahi kiʻi ʻoniʻoni e hoʻomaikaʻi i ka hana pale kinoea o ka substrate.Nā hiʻohiʻona hana:
Paipai maikaʻi;ʻO ka mānoanoa o ka papa PVDC maʻamau 2 ~ 3um, me ka uku haʻahaʻa;ʻAʻole hiki ke kū i ka kuke wela wela.
2) PVDC laminated composite membrane
Hoʻokumu ʻia ia me nā kiʻi ʻoniʻoni hoʻokahi-layer, a hoʻopaʻa ʻia kēlā me kēia papa me ka mea hoʻopili.Hiki ke mahele ia i:
Lamination maloʻo (solvent) a me ka lamination ʻole solvent.
Nā hiʻohiʻona hana:
A. Mewaiwai keakea kiʻekiʻe a me ka hoʻolālā maʻalahi, hiki ke hoʻohuiʻia me BOPA, CPP, CPE, BOPP, BOPET, PVC a me nā kiʻiʻoniʻoni'ē aʻe (no ka laʻana, BOPP, PET, PA hiki ke hoʻohanaʻia e like me ka papa paʻi waho loa, PE, CPP a me nā hopena hoʻopaʻa wela maikaʻi e hiki ke hoʻohanaʻia. ma ke ʻano o ka pae hoʻopaʻa wela, hiki ke hoʻohana ʻia ke kūpaʻa puncture maikaʻi o PA e like me ke ʻano o ka pale ʻana o ka puncture, a hiki ke hoʻohana ʻia ʻo PVDC ma ke ʻano he pale pale e pale ai i ka oxygen a me ka wai).
B. Kūleʻa wela maikaʻi.Hiki ke hana ʻia i ke kiʻi ʻoniʻoni kiʻekiʻe kiʻekiʻe a me ka haʻahaʻa haʻahaʻa haʻahaʻa me ka pale wela o - 20 ℃ ~ 121 ℃;
ʻO nā waiwai mechanical a me ka wela-sealing maikaʻi, kūpono no nā ʻano mīkini pahu like ʻole, paʻi kala, kaupalena ʻia e ka kiʻiʻoniʻoni hoʻokahi, ʻoiai ʻo ka mānoanoa o kēlā me kēia papa ʻaʻole hiki ke lahilahi a ʻaʻole i nui ka nui o nā papa composite. ma mua o 5 papa).
3) PVDC multilayer co-extruded composite kiʻiʻoniʻoni
Hoʻokuʻu ʻia nā ʻano plastics e nā extruders he nui i ka manawa hoʻokahi ma o ke poʻo make e hana i kahi kiʻiʻoniʻoni me ka hoʻonohonoho hoʻonohonoho ʻana, ʻike ʻia ka hoʻopuka interlayer, paʻa paʻa a me ka mānoanoa interlayer kūlike.Wahi a nā ʻano hana like ʻole, hiki ke hoʻokaʻawale ʻia i co-extrusion blown film a me co-extrusion cast film.Hoʻohana pinepine ʻia nā mea PVDC ma ke ʻano he papa waena waena o ka kiʻiʻoniʻoni composite.Nā hiʻohiʻona hana: ka pale kiʻekiʻe, ka maʻemaʻe maikaʻi, hoʻohana ʻia ka resin adhesive no ka hoʻopaʻa ʻana, e pale aku i ka pilikia o ke koena solvent i loko o ka composite maloʻo (solvent-based), a hiki ke kuke ʻia ma lalo o 100 degere;Hiki ke hana ʻia ke kiʻiʻoniʻoni e ka hana wela lua ma o ka hoʻohana ʻana i ka hana lālā kahe;Nui nā papa i hiki ke hana ʻia, a i kēia manawa ua hiki i ka 13 papa.Hiki ke hana ʻia ka mānoanoa interlayer, hiki ke mālama i ka nui o ka resin me ke kumu kūʻai kiʻekiʻe a loaʻa i kahi hana ʻoi aku ka maikaʻi.
