Kaʻina hana o ka polyethylene film

ʻO ka kiʻiʻoniʻoni Polyethylene (PE) he mea lahilahi a maʻalahi i hana ʻia mai ka polyethylene polymer i hoʻohana nui ʻia no ka hoʻopili ʻana, pale, a me nā noi ʻē aʻe.Hiki ke hoʻokaʻawale nui ʻia ke kaʻina hana o ka polyethylene film i kekahi mau pae:

1. ʻO ka hana Resin: ʻO ka hana mua i ka hana hana ʻana ʻo ia ka hana ʻana i ka mea maka, ʻo ia ke ʻano o ka resin polyethylene.Hana ʻia kēia ma o ka polymerization, kahi kaʻina hana kemika e hana i nā kaulahao lōʻihi o nā molekole polymer mai nā monomers e like me ka ethylene.Hoʻopili ʻia ka resin, maloʻo, a mālama ʻia no ka hana hou ʻana.

1. Extrusion: ʻO ka hana aʻe e hoʻohuli i ka resin i kahi kiʻiʻoniʻoni.Hana ʻia kēia ma ke kau ʻana i ka resin ma kahi extruder, kahi mīkini e hoʻoheheʻe i ka resin a hoʻoikaika iā ia ma kahi puka liʻiliʻi i kapa ʻia he make.Hoʻomaʻalili ka resin hehee a paʻa i ka wā e hoʻokuʻu ʻia ai, e hana ana i kahi pepa kiʻiʻoniʻoni.

1. ʻO ka hoʻoluʻu a me ka wili ʻana: Ma hope o ka hoʻokuʻu ʻia ʻana o ke kiʻiʻoniʻoni, hoʻomaha ʻia a hiki i ka lumi wela a ʻeha i ka ʻōwili.Hiki ke kikoo a hoʻonohonoho ʻia ke kiʻiʻoniʻoni i ka wā o kēia kaʻina hana, e hoʻomaikaʻi ai i kona mau ʻano mechanical a hoʻonui i ka ʻaʻahu.

1. Kalendering: Hiki ke hana hou ʻia ke kiʻiʻoniʻoni ma o ke kaʻina hana i kapa ʻia he calendering, kahi e hele ai i loko o kahi pūʻulu o nā wili wela e hana i kahi ʻili laulima a ʻālohilohi.

1. Lamination: Hiki ke hoʻohui ʻia ke kiʻiʻoniʻoni me nā mea ʻē aʻe e hana i kahi hale laminated.Hoʻohana pinepine ʻia kēia me ka hoʻohana ʻana i kahi ʻāpana paʻa ma waena o ʻelua a ʻoi aku paha o nā ʻāpana o ke kiʻiʻoniʻoni, e hāʻawi ana i nā waiwai pale i hoʻomaikaʻi ʻia a hoʻonui i ka hana o ka huahana hope.

1. Paʻi a ʻokiʻoki: Hiki ke paʻi ʻia ka huahana kiʻiʻoniʻoni hope me nā hiʻohiʻona a i ʻole nā ​​kiʻi i makemake ʻia, a laila ʻokiʻoki i ka nui a me ke ʻano i makemake ʻia no nā noi kikoʻī.

Hiki ke ʻokoʻa kēia mau pae ma muli o nā waiwai i makemake ʻia a me ka hoʻohana hope ʻana o ka polyethylene film, akā mau ke kaʻina hana maʻamau.
