Ihe nkiri ihe nkiri dị elu nke a na-ahụkarị bụ ndị a:
1. Ihe PVDC (Polyvinylidene Chloride)
Polyvinylidene chloride (PVDC) resin, nke a na-ejikarị dị ka ihe mejupụtara ma ọ bụ ihe monomer na ihe nkiri a na-ekekọta, bụ ihe nkwakọ ngwaahịa dị elu nke a na-ejikarị eme ihe.Ojiji nke ihe nkiri mkpuchi PVDC bụ nnukwu.Ihe nkiri mkpuchi PVDC bụ ojiji nke polypropylene (OPP), polyethylene terephthalate (PET) dị ka ihe ndabere.N'ihi na elu nro okpomọkụ nke dị ọcha PVDC, solubility nke PVDC dị nso ya decomposition okpomọkụ, na miscibility na general plasticizer adịghị mma, kpo oku ịkpụzi siri ike na-esi ike etinye ya ozugbo.Ihe eji eme ihe nkiri PVDC n'ezie bụ copolymer nke vinylidene chloride (VDC) na vinyl chloride (VC), yana acrylic methylene (MA) copolymerization mere nke kacha mma ihe nkiri mgbochi.
2. Ihe Nkwakọ ngwaahịa Nylon
Ihe nkwakọ ngwaahịa naịlọn tupu - jiri "nylon 6" mee ihe ozugbo.Mana ikuku "nylon 6" adịghị mma.Naịlọn (MXD6) nke sitere na polycondensation nke m-dimethylamine na adipic acid dị okpukpu 10 karịa ikuku karịa "nylon 6", ebe ọ na-enwekwa nghọta dị mma na nkwụsị nkwụsị.A na-ejikarị eme ihe nkiri nkwakọ ngwaahịa dị elu maka ihe mgbochi dị elu chọrọ nkwakọ ngwaahịa na-agbanwe agbanwe.FDA kwadoro ya maka ịdị ọcha nri.Ihe kachasị ya dị ka ihe nkiri bụ na ihe mgbochi adịghị ada na ịrị elu nke iru mmiri.Na Europe, a na-eji nylon MXD6 mee ihe dị ka ihe ọzọ na ihe nkiri PVDC n'ihi nsogbu nchebe gburugburu ebe obibi a ma ama.
3. Ihe EVOH
EVOH bụ ihe mgbochi dị elu nke a na-ejikarị eme ihe.
Ụdị ihe nkiri nke ihe a na mgbakwunye na ụdị nke na-adịghị, e nwere ụdị nkwụsịtụ ụzọ abụọ, ụdị evaporation aluminum, mkpuchi mkpuchi na ihe ndị ọzọ.Ụzọ abụọ na-agbatị na okpomọkụ - ngwaahịa na-eguzogide ọgwụ maka nkwakọ ngwaahịa aseptic.
4. Ihe nkiri mkpuchi oxide inorganic
PVDC, nke a na-ejikarị eme ihe dị ka ihe mgbochi dị elu, nwere ọchịchọ iji ihe nkwakọ ngwaahịa ndị ọzọ dochie ya n'ihi na ihe mkpofu ya ga-emepụta HCl mgbe ọkụ.Dịka ọmụmaatụ, ihe a na-akpọ ihe nkiri mkpuchi nke a na-eme mgbe mkpuchi nke SiOX (silicon oxide) na fim nke ihe ndị ọzọ na-elebara anya, na mgbakwunye na ihe nkiri mkpuchi silicon oxide, e nwere ihe nkiri alumina evaporation.Ịrụ ọrụ gas na-ekpuchi mkpuchi bụ otu ihe ahụ nke mkpuchi silicon oxide nwetara site n'otu ụzọ ahụ.
N'afọ ndị na-adịbeghị anya, multilayer composite, ngwakọta, copolymerization na evaporation technology etolitela ngwa ngwa.Ihe nkwakọ ngwaahịa dị elu dị ka vinyl vinyl glycol copolymer (EVOH), polyvinylidene chloride (PVDC), polyamide (PA), polyethylene terephthalate (PET) multilayer composite material na silicon oxide compound evaporation film ka emepụtara, ọkachasị ngwaahịa ndị a bụ karịa. na-ele anya: MXD6 polyamide nkwakọ ngwaahịa;Polyethylene glycol naphthalate (PEN);Ihe nkiri evaporation silicon oxide, wdg.
