Ihe nkiri coextrusion multilayer
Iji gbatịa ndụ nchekwa nke nri, ọgwụ na ihe ndị ọzọ, ọtụtụ n'ime ihe oriri na nkwakọ ngwaahịa ọgwụ ugbu a na-eji ihe nkiri mejupụtara ihe mejupụtara multi-layer co-extrusion.Ka ọ dị ugbu a, e nwere ihe nkwakọba ihe mejupụtara abụọ, atọ, ise, asaa, itoolu na ọbụna iri na otu.Multi-layer co-extrusion film bụ ihe nkiri nke na-emepụta ihe dị iche iche nke plastik site na otu anwụ anwụ n'otu oge site na ọtụtụ ọwa, nke nwere ike inye egwuregwu na uru nke ihe dị iche iche.
Ihe nkiri mejupụtara ihe nkiri mejupụtara ọtụtụ oyi akwa bụ polyolefin.Ka ọ dị ugbu a, ihe ndị a na-ejikarị eme ihe gụnyere: polyethylene / polyethylene, polyethylene / vinyl acetate copolymer / polypropylene, LDPE / adhesive Layer / EVOH / adhesive Layer / LDPE, LDPE / adhesive Layer / EVOH / EVOH / Adhesive Layer / LDPE.Enwere ike ịhazi oke nke oyi akwa ọ bụla site na usoro extrusion.Site n'ịgbanwe oke nke oyi akwa mgbochi na iji ihe mgbochi dị iche iche, ihe nkiri ahụ nwere ihe mgbochi dị iche iche nwere ike ịmepụta ya n'ụzọ dị nro, na ihe mkpuchi okpomọkụ nwekwara ike gbanwee ma kenye ya iji gboo mkpa nke nkwakọ ngwaahịa dị iche iche.Nke a multilayer na multi-function co-extrusion compound bụ isi ntụziaka nke mmepe nke nkwakọ ihe nkiri ihe n'ọdịnihu.
