EVA / PEVA Cast Film Extrusion Line

Hiki ke hoʻohana ʻia ke kiʻi ʻoniʻoni EVA e like me ka encapsulation pā uila, a i ʻole ke kiʻi ʻoniʻoni no ka lamination aniani.
Loaʻa nā huahana kiʻi ʻoniʻoni PEVA i nā noi like ʻole no ka pale ʻauʻau, nā mīkina lima, ka lole umbrella, ka lole papaʻaina, ka lole ua etc.
Hoʻopili ʻia kēia resin thermoplastic me nā resins ʻē aʻe e like me LDPE a me LLDPE a i ʻole he ʻāpana o kahi kiʻi multilayer.I nā huila a me nā copolymers, ʻo ka pākēneka o ka EVA mai 2% a 25%.Hoʻonui ia i ka mālamalama a me ka hoʻopaʻa ʻana o nā olefins (LDPE/LLDPE) akā hoʻohana pinepine ʻia ka pākēneka kiʻekiʻe o EVA e hōʻemi i ka helu heheʻe.Hoʻonui ia i ka hana haʻahaʻa wela.Ma keʻano holoʻokoʻa, e hilinaʻi nā waiwai mechanical i ka ʻike vinyl acetate;ʻoi aku ka kiʻekiʻe o kāna pākēneka, ʻo ka haʻahaʻa ka pale i ke kinoea a me ka makū a ʻoi aku ka maikaʻi o ka mālamalama.
ʻO ka EVA wale nō kahi pale awelika i nā kinoea a me ka makū, ʻaʻole ia he koho maikaʻi no nā noi hoʻopili meaʻai a, no laila, ua pani ʻia e ka metallocene PE i ka nui o kēia mau noi.Hāʻawi pū ʻo mPE i ka pā wela wikiwiki, a ʻoi aku ka maikaʻi o nā waiwai hoʻohaʻahaʻa haʻahaʻa, e hiki ai i nā kiʻiʻoniʻoni ʻoniʻoni a me nā ʻōpala.Eia nō naʻe, noho mau ʻo EVA i mea hoʻopihapiha koʻikoʻi a e ikaika mau ka koi no nā noi meaʻai ʻole.
