ʻO ka ʻeke PE he ʻeke maʻamau i ko mākou ola i kēlā me kēia lā, hoʻohana ʻia no nā ʻano huaʻai a me nā mea ʻai meaʻai, ʻeke kūʻai, ʻeke huahana mahiʻai, a me nā mea ʻē aʻe. ʻO ke kaʻina hana ʻeke PE e loaʻa ana i nā ʻāpana plastik - hoʻoheheʻe wela ka hui ʻana - extrusion kikoo - hoʻomaʻamaʻa uila -; ʻO ka ʻeke PE ka mea nui ma luna o nā kaʻina hana, maʻalahi ma hope o nā kaʻina hana ʻekolu: puhi kiʻiʻoniʻoni ------ paʻi ------ hana ʻeke.
E hoʻolohe i ke kaʻina paʻi ʻeke PE i ke aha?
ʻO ka polyethylene, maikaʻi haʻahaʻa haʻahaʻa kū'ē (hoʻohana i ka mahana a hiki i -70 ~-100), kemika paʻa, ka nui o ka waikawa a me ka alkali erosion (me ka oxidizing acid intolerance), insoluble i ka laulā maʻamau i ka lumi wela, haʻahaʻa absorption, maikaʻi uila insulation hana. Eia nō naʻe, paʻakikī ka polyethylene i ke koʻikoʻi o ke kaiapuni (kemika a me ka hana mechanical) a ʻilihune i ka wā ʻelemakule wela. ʻOkoʻa nā waiwai o ka polyethylene mai kēlā me kēia ʻano, ma muli o ke ʻano mole a me ka nui. Hiki ke loaʻa nā huahana me nā ʻano like ʻole (0.91-0.96 G/CM3) e nā ʻano hana like ʻole. Hiki ke hana ʻia ka polyethylene e nā ʻano hana thermoplastic maʻamau (e ʻike i ka hana Plastics).
He aha nā memo e pili ana i ke kaʻina hana ma lalo nei?
Pono ke kaʻina puhi kiʻiʻoniʻoni e nānā i kēia mau mea:
1. Ka hoʻohālikelike waiwai: e like me nā koi like ʻole o nā ʻeke PE, ka hoʻomākaukau ʻana i nā ʻāpana like ʻole o nā mea maka. No ka laʻana: anti-static, anti-rust, mitigation, conductivity uila, biodegradation a me nā koi ʻē aʻe, e hoʻohui i nā ʻano mea hoʻohui kōkua like ʻole: e hoʻohana i ka ʻulaʻula, ʻeleʻele, kala a me nā kala ʻē aʻe, e hoʻohui i nā ʻano o nā pāpale kala. E like me ka ʻike maopopo, ka paʻakikī, ka ikaika o ka waimaka, ka ʻoki ʻana i ka vacuum a me nā koi ʻē aʻe, e hoʻololi i nā ʻano mea like ʻole a i ʻole nā mea hana PE. No ka laʻana: e like me nā koi kūikawā, e hoʻoikaika i nā koi o ke aniani kiʻekiʻe, ka haehae ikaika, ka wehe maikaʻi, i mea e hoʻololi ai i ka hapa o nā mea maka.
2. ke kaʻina hana o ka puhi ʻana i ka paʻi kiʻiʻoniʻoni, ka pono o ka hana uila, i kēia manawa e hoʻolohe i ka ikaika o ka hana uila, e hōʻoia i ka ikaika o ka hana uila uila PE drum (DAYIN) e hōʻoia i ka hoʻopili ʻana i ka inika.
3.i ke kaʻina hana o ka puhi kiʻiʻoniʻoni, e like me nā koi kūikawā o ke kiʻiʻoniʻoni, ka wehe hoʻokahi, ka wehe pālua, ka peluʻana, ka pōʻino o ke kaomi, ka embossing, ka hoʻonui a me nā hana'ē aʻe.
Pono ke kaʻina hana paʻi ʻeke PE i kēia mau mea:
1. ka inika paʻi: ka inika wai, ka'īnika hoʻomaloʻo wikiwiki, ka'īnika iʻikeʻoleʻia, ka'īnika hoʻololi kala, ka'īnika anti-counterfeiting, ka'īnika hoʻokomo, ka'īnika conductive, ka'īnika uila haʻahaʻa, ka'īnika matte a me nāʻano'īnika'ē aʻe he'īnika.
2. Paʻi paʻi: e like me nā koi maikaʻi o ka paʻi ʻana, hoʻohana ʻia ka paʻi gravure (pā keleawe) a me ka flexography (offset). ʻO kēia mau ʻano paʻi ʻokoʻa ʻelua.
3. E like me ka paʻakikī o ka paʻi ʻana a me ka paʻakikī kala, koho i ke ʻano paʻi: paʻi monochrome, paʻi ʻelua ʻaoʻao monochrome, paʻi kala ʻaoʻao hoʻokahi, paʻi kala ʻelua ʻaoʻao.
4. E like me nā koi kūikawā o nā ʻano paʻi, e like me nā hiʻohiʻona o ka discoloration, anti-counterfeiting, conductivity uila, adhesives a pēlā aku, e koho i ka inika a i ʻole nā mea hoʻohui.
