ʻO ka hoʻohanohano EVOH

EVOH Pōkole Pōkole: ʻO EVOH barrier ka mea i hoʻohana nui ʻia. ʻO kēia ʻano mea kiʻiʻoniʻoni i hoʻohui ʻia i ke ʻano ʻaʻole i kau ʻia, aia nā ʻano ʻelua ala, ʻano alumini i waiho ʻia i ka mahu, ʻano uhi hoʻopili, ʻelua ʻaoʻao ʻaoʻao aia nā ʻāpana pale wela no nā huahana sterile. ʻO nā waiwai pale EVOH e pili ana i ka maʻiʻo o ka ethylene, e like me ka piʻi ʻana o ka ethylene ma ke ʻano maʻamau, e emi ana nā waiwai pale kinoea, akā maʻalahi ka hana. ʻO ka hiʻohiʻona koʻikoʻi ʻo EVOH ʻo ia ka maikaʻi o nā waiwai pale kinoea a me ke kaʻina hana maikaʻi loa, ʻoi aku ka maikaʻi o ka transparency, gloss, mechanical strength, flexibility, abrasion resistance, cool resistance and surface strength is very good. I loko o ke kahua hoʻopili, EVOH papa pale i hana ʻia me ka membrane composite intermediate, hoʻohana ʻia i loko o nā ʻōpala paʻakikī a palupalu; no ka ʻeke aseptic i ka ʻoihana meaʻai, ipu wela a me nā ʻeke kuke, hoʻopili i nā huahana waiu, ʻiʻo, nā wai hua canned a me nā mea ʻono; nā huahana meaʻai ʻole, ka hoʻopili ʻana no nā solvents, pesticides, kemika, ka ea-conditioned structure, i hoʻopaʻa ʻia me nā barela o ka ʻaila, a me nā mea uila ʻē aʻe. I loko o ka ʻeke meaʻai, hiki ke hoʻololi i ka ipu aniani a me nā pahu metala, nā ʻoihana aquaculture hale e lawe aku i ka iʻa ma ka hoʻohana ʻana i ka PE / EVOH / PA / RVOH / PE ʻelima-layer co-extruded film vacuum packaging. ʻO ka hoʻolalelale ʻana i ka membrane composite EVOH aʻo ke aʻo ʻana hoʻi i waho o ka EVOH stretch orientation, nā waiwai pale kinoea hou o EVOH kiʻiʻoniʻoni ʻekolu manawa o ka hana ʻana o ke kiʻi ʻoniʻoni EVOH ʻaʻole i kau ʻia. Eia kekahi, hiki ke hoʻopili ʻia ʻo EVOH ma ke ʻano he mea pale i nā mea hoʻopihapiha resin synthetic, e hoʻoikaika i ka hopena o nā waiwai pale.

ʻO ka hōʻuluʻulu pōkole o nā pono o EVOH:

▪Ma lalo o ka haʻahaʻa haʻahaʻa haʻahaʻa hiki ke hāʻawi i ka hana pale kiʻekiʻe

▪ʻO ka hopena pale maikaʻi o nā kemika, me ka hapa nui o nā momona a me nā aila, nā waikawa a me nā pesticides solvents.

▪Kiʻekiʻe Transparency: e hōʻoia i ka hana o ka maʻalahi o ka hoʻokō

▪ʻala ʻala, ʻono maikaʻi

▪EVOH me nā ʻano polymers e hoʻokō i ka coextrusion
