ʻO ka ʻeke PE kahi ʻeke maʻamau i ko kākou ola o kēlā me kēia lā, hoʻohana ʻia no nā ʻano ʻōpala huaʻai a me nā mea kanu, nā ʻeke kūʻai, nā ʻeke huahana mahiʻai, a me nā mea ʻē aʻe. ʻOi aku ka paʻakikī o ka hana ʻana i kahi ʻeke ʻili plastik maʻalahi. ʻO ke kaʻina hana hana ʻeke PE e pili ana i nā ʻāpana plastik - ka hoʻohuihui ʻana i ka wela - ka hoʻolōʻihi ʻana i ka extrusion - ka mālama uila -; ʻO ka ʻeke PE nā kaʻina hana i luna aʻe, i hoʻomaʻalahi ʻia ma hope o nā kaʻina hana ʻekolu: ka puhi ʻana i ka ʻili ------ paʻi ------ hana ʻeke.
He aha ka mea e pono ai ke nānā aku i ke kaʻina hana paʻi ʻeke PE?
ʻO ka Polyethylene, kūpaʻa haʻahaʻa maikaʻi loa (hoʻohana i ka mahana a hiki i -70 ~ -100), kūpaʻa kemika, ka hapa nui o ka ʻino ʻakika a me ka alkali (me ka hoʻomanawanui ʻole i ka waikawa oxidizing), ʻaʻole hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe maʻamau i ka mahana o ka lumi, haʻahaʻa ka omo ʻana, hana insulation uila maikaʻi. Eia nō naʻe, he ʻano koʻikoʻi ka polyethylene i ke kaumaha o ke kaiapuni (hana kemika a me ka mīkini) a maikaʻi ʻole i ka ʻelemakule wela. ʻOkoʻa nā waiwai o ka polyethylene mai nā ʻano a i nā ʻano, ma muli nui o ke ʻano molekala a me ka nui. Hiki ke loaʻa nā huahana me nā densities like ʻole (0.91-0.96 G/CM3) ma o nā ʻano hana like ʻole. Hiki ke hana ʻia ka Polyethylene e nā ʻano hana thermoplastic maʻamau (e nānā i ka hana ʻana o Plastics).
He aha nā memo e pili ana i ke kaʻina hana ma ke kikoʻī ma lalo nei?
Pono ke kaʻina hana puhi kiʻiʻoniʻoni e hoʻolohe i nā mea aʻe:
1. Ka nui o nā mea maka: 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, electrical conductivity, biodegradation a me nā koi ʻē aʻe, e hoʻohui i nā ʻano mea hoʻohui kōkua like ʻole e like me: e hoʻohana i ka ʻulaʻula, ʻeleʻele, kala a me nā kala ʻē aʻe, e hoʻohui i nā ʻano pāpale kala like ʻole. E like me ka transparency, toughness, strength haehae, vacuum extraction a me nā koi ʻē aʻe, e hoʻololi i nā ʻano lama like ʻole a i ʻole nā lama o nā mea PE. No ka laʻana: e like me nā koi kūikawā, e hoʻoikaika i nā koi o ka transparency kiʻekiʻe, ka haehae ikaika, ka wehe maikaʻi, i mea e hoʻololi ai i ka nui o nā mea maka.
2. ke kaʻina hana o ka paʻi ʻana i ka kiʻiʻoniʻoni, pono no ka hana uila, i kēia manawa e hoʻolohe i ka ikaika o ka hana uila, e hōʻoia i ka lawa ʻana o ka ikaika hana uila o ka mea pahu PE (DAYIN) e hōʻoia i ka hoʻopili ʻana o ka ʻīnika.
3. i ke kaʻina hana o ka puhi ʻana i ka ʻoniʻoni, e like me nā koi kūikawā o ke kiʻiʻoniʻoni, ka wehe ʻana hoʻokahi, ka wehe ʻana pālua, ka pelu ʻana, ka hōʻino ʻana o ke kiko kaomi, ka embossing, ka hoʻonui ʻana a me nā hana ʻē aʻe.
Pono ke kaʻina hana paʻi ʻeke PE e hoʻolohe i nā mea aʻe:
1. ʻīnika paʻi: ʻīnika wai, ʻīnika maloʻo wikiwiki, ʻīnika ʻike ʻole ʻia, ʻīnika hoʻololi kala, ʻīnika anti-hoʻopunipuni, ʻīnika induction, ʻīnika conductive, ʻīnika uila haʻahaʻa, ʻīnika matte a me nā ʻano ʻīnika ʻē aʻe he ʻīnika.
2. Papa paʻi: e like me nā koi maikaʻi o ka ʻike paʻi, hoʻohana ʻia ka paʻi gravure (papa keleawe) a me ka paʻi flexography (offset). ʻElua mau ʻano paʻi like ʻole.
3. E koho i ke ʻano paʻi e like me ka paʻakikī o ka ʻike paʻi a me ka paʻakikī o ke kala: paʻi monochrome, paʻi ʻaoʻao ʻelua monochrome, paʻi kala ʻaoʻao hoʻokahi, paʻi kala ʻaoʻao ʻelua.
4. E like me nā koi kūikawā o nā ʻano paʻi, e like me nā ʻano o ka discoloration, anti-counterfeiting, conductivity uila, adhesives a pēlā aku, koho i nā ʻīnika like ʻole a i ʻole nā mea hoʻohui.
