I ka hana kiʻiʻoniʻoni, hoʻokuʻu ʻia kekahi ʻano mea maka ma luna o kekahi ʻano kiʻiʻoniʻoni i hana ʻia a i ʻole ma luna o nā ʻano kiʻiʻoniʻoni like ʻole i hana ʻia a hoʻohana ʻia ka mea hoʻopili e hoʻopaʻa pū ai e hana i nā kiʻiʻoniʻoni multilayer.Kapa ʻia kēia huahana he kiʻi ʻoniʻoni.Kiʻiʻoniʻoni co-extrudedLoaʻa ka hapa nui o nā hiʻohiʻona o ke kiʻi ʻoniʻoni, akā aia hoʻokahi ʻokoʻa, ʻo ia hoʻi, hoʻokuʻu ʻia nā papa āpau o ke kiʻi co-extruded i ka manawa like, a hoʻopaʻa ʻia nā papa e ka hoʻoheheʻe wela me ke kaʻina hana lamination.
ʻO ke kiʻi kiʻiʻoniʻoni ka hapa nui o ka plastic, akā hiki ke hoʻohana ʻia ka pepa, ka pepa metala (maʻamau ka alumini) a i ʻole ka lole.ʻO nā papa āpau o kakiʻiʻoniʻoni co-extrudedhoʻokuʻu ʻia i ka manawa like, no laila ʻaʻohe alumini alumini, pepa a me nā mea ʻole-plastic ʻē aʻe.
He kiʻi ʻoniʻoni ʻoniʻoni i hui pū ʻiahana ʻia me ka hoʻohana ʻana i nā extruders lehulehu e hoʻopau i ka resin me ka hana pale kiʻekiʻe a me ka hoʻoheheʻe ʻana o nā resins ʻē aʻe ma o ka make maʻamau.ʻO ka multi-layer co-extrusion composite he kaʻina hana ʻōmaʻomaʻo ʻōmaʻomaʻo, ʻoi aku hoʻi no ka ʻoihana hoʻopihapiha meaʻai o kēia manawa, ʻo nā mea maka i hoʻohana ʻia he mau mea i hōʻoia ʻia e ka United States Food and Health and Safety Agency, a ua hoʻolako ʻia nā mea maka i kēlā me kēia. papa e kahi paipu hoʻokele kūikawā.ʻAʻole ʻike ʻia nā mea maka a me ka haumia o ke kaiapuni i ke kaʻina hana.Hana ʻia kona papa hope me ka LLDPE i hoʻololi ʻia e like me ka mea maka, ʻaʻole ia he mea ʻawaʻawa i ke kaiapuni, ka meaʻai a me ke kino kanaka a ʻaʻole e ʻike ʻia i ka pūhui maloʻo kuʻuna, ʻo ia hoʻi, ka mea i kapa ʻia ke koena solvent, me ka ʻole o ka haumia kinoea;He ʻokoʻa nō hoʻi ia mai ka hui ʻana maloʻo, ka hoʻohuihui ʻana i ka solvent-free a me ke kaʻina hana hoʻohuihui hoʻokahi-layer extrusion, a pono e hoʻomaloʻo i ka umu no ka mālama ʻana, no laila ʻoi aku ka liʻiliʻi o ka ikehu.Eia kekahi, ʻo ka multi-layer co-extrusion composite kaʻina hana pū kekahi i nā mea maikaʻi aʻe.
(1) Ke hoʻohana nei ke kaʻina hana composite multi-layer co-extrusion i nā ʻano resins me nā hana like ʻole.Hoʻokahi wale nō kaʻina hana o ka puhi ʻana i hiki ke hoʻohana ʻia e hana i nā huahana kiʻiʻoniʻoni multi-functional, hiki ke hōʻemi i nā kumukūʻai hana.Eia kekahi, hiki iā ia ke hōʻemi i ka hana pono o ka resin raw material i ka liʻiliʻi liʻiliʻi, a hiki i ka mānoanoa liʻiliʻi o ka papa hoʻokahi ke hiki i 2 ~ 3 μm.Hiki iā ia ke hōʻemi nui i ka hoʻohana ʻana i ka resin pipiʻi, no laila e hōʻemi ana i ke kumu kūʻai.
(2) Hiki ke hoʻohālikelike i ka ʻenehana co-extrusion multi-layer hiki ke hoʻohālikelike i nā ʻano mea maka i nā hui like ʻole e hoʻohana piha ai i nā mea maka me nā waiwai like ʻole a me ke ʻano i ka manawa hoʻokahi.ʻAʻole ia i kaupalena ʻia e nā kikoʻī huahana kūpono o ka mākeke a hiki ke hoʻokō pono i nā pono o nā manawa hoʻopili like ʻole.ʻOi aku ka nui o nā papa, ʻoi aku ka maʻalahi o ka hoʻolālā hale a me ka haʻahaʻa o ke kumukūʻai.
(3) Kiʻekiʻe composite hana co-extrusion composite kaʻina hoʻohui i hoʻoheheʻe ʻia a me ka resin base.He ikaika ʻili kiʻekiʻe kēia kaʻina hana maʻamau a hiki i 3N/15mm a ʻoi aʻe paha i kūpono no nā mea hoʻopihapiha maʻamau.No nā huahana me nā koi ikaika peel kiʻekiʻe, hiki ke hoʻohui ʻia ka resin thermosensitive no ka composite.I kēia manawa, hiki i ka ikaika peel ke hiki i 14N / 15mm, a i ʻole ke kiʻekiʻe.
(4) Hiki i nā huahana composite multi-layer co-extruded ke uhi kokoke i nā māla hoʻopili āpau, me ka meaʻai, nā huahana kemika i kēlā me kēia lā, nā mea inu, nā lāʻau lapaʻau, nā kiʻiʻoniʻoni pale a me nā huahana aerospace.I kēia manawa, nui nā huahana composite maloʻo ma Kina i lawe i ke kaʻina hana co-extrusion ma waho.ʻAʻole hiki ke hana ʻia nā paipu niho niho ma ke kaʻina hana hui maloʻo.ʻO nā huahana alumini alumini pepa.ʻIke ʻia ka Aerospace a me nā huahana ʻē aʻe e ke kaʻina co-extrusion.Me ka noiʻi hohonu a me ka hoʻomau hou ʻana o ka resin composite coextrusion, ʻenehana a me nā mea hana, e hoʻonui ʻia ka multi-layer coextrusion composite i kahi ākea ākea.
