1, polyester film hoʻolauna

Kapa ʻia ke kiʻi ʻoniʻoni polyester (PET) (kiʻi māmā, kiʻiʻoniʻoni polyester, pepa sensitive, kiʻiʻoniʻoni polyester, kiʻiʻoniʻoni benzene tin, cellophane, kiʻi hoʻokuʻu), he polyethylene terephthalate e like me nā mea maka, ka hoʻohana ʻana i ke ʻano extrusion i loko o ke kiʻi mānoanoa, a laila hoʻopololei ʻia nā ʻaoʻao ʻelua i hana ʻia me nā mea kiʻiʻoniʻoni.

ʻO ke kiʻiʻoniʻoni polyester home (kiʻi polyester, kiʻiʻoniʻoni hoʻomalu kaiapuni, kiʻi ʻoniʻoni PET, kiʻi ʻoniʻoni a me nā mea paʻi a me nā mea hoʻohana ʻē aʻe), hoʻohana nui ʻia i ke aniani fiber reinforced plastic ʻoihana, hale hana hale, ʻoihana paʻi, lāʻau lapaʻau a me ke olakino.

I kēia manawa, ua hoʻomohala maikaʻi ʻo Kina i kahi kiʻi ʻoniʻoni PET twist, ʻaʻohe mea ʻawaʻawa, ʻaʻohe kala, ʻākala, ʻūlū-kūʻokoʻa, hanu, palupalu, ikaika, acid-alkali grease a me ka pale pale, ʻaʻole makaʻu i ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa.ʻO kahi mea ʻawaʻawa ʻole, ʻike ʻia i ka recyclable, hoʻohana nui ʻia i nā ʻano inu like ʻole, ka wai mineral a me ka paʻi kiʻiʻoniʻoni, i kēia manawa i hoʻohana nui ʻia i ka honua kekahi o nā mea hoʻopihapiha.

ʻO ke kiʻi ʻoniʻoni ʻo Mylar kahi ʻano kiʻiʻoniʻoni polymer plastic, no kāna mau waiwai piha maikaʻi a ʻoi aku ka makemake o ka hapa nui o nā mea kūʻai.No ka mea, ʻaʻole hiki i ka hana a Kina a me ka pae ʻenehana ke hoʻokō i nā pono o ka mākeke, pono kekahi e hilinaʻi i ka lawe ʻana mai.

2, nā waiwai kiʻiʻoniʻoni polyester

He polymer kiʻekiʻe ʻo PET, ma muli o ka condensation dehydration o ka ethylene terephthalate.Loaʻa ka Glycol terephthalate ma ka esterification o terephthalic acid a me glycol.He waiu keʻokeʻo a i ʻole melemele ʻōmaʻomaʻo ʻo PET, polymer crystalline kiʻekiʻe me ka ʻili ʻālohilohi.

Loaʻa i ka PET nā waiwai maikaʻi (kūʻai wela, kūpaʻa kemika).ʻO ka ikaika a me ka paʻakikī, ka uila uila, palekana, a me nā mea'ē aʻe), maʻalahi, hoʻohana nuiʻia e like me ka fiber, film, engineering plastics, polyester bottles a pēlā aku.

Loaʻa i ka PET nā waiwai kino a me nā mechanical maikaʻi i kahi ākea ākea, ka mahana hoʻohana lōʻihi a hiki i 120 ℃, insulation uila maikaʻi loa, ʻoiai ma ke kiʻekiʻe kiʻekiʻe a me ke alapine kiʻekiʻe, ʻoi aku ka maikaʻi o kāna mau mea uila, akā maikaʻi ʻole ka pale corona, anti-toxic , kū'ē i ka wā, kūpa'a kū'ē kemika, kolo, kū'ē luhi, kū'ē kū'ē, kūpa'a dimensional maika'i loa.ʻO ka haʻahaʻa haʻahaʻa o ka wai, ka pale ʻana i nā ʻakika nāwaliwali a me nā mea hoʻoheheʻe kūlohelohe, akā ʻaʻole pale i ka wela i ka hoʻokomo ʻana i ka wai, ʻaʻole ka pale alkali.

ʻO ka maʻamau, ʻaʻole kala ʻole ʻo PET, kiʻi ʻoniʻoni (hiki ke hoʻohui ʻia nā ʻāpana additive i loaʻa iā ia ke kala), nā waiwai mechanical maikaʻi loa, kiʻekiʻe rigidity, paʻakikī a paʻakikī, kūpaʻa puncture, kūpaʻa friction, kiʻekiʻe wela a me ka haʻahaʻa haʻahaʻa kūʻē, kūʻē kemika, ʻaila. ʻO ke kūpaʻa, ka paʻa ʻana o ka ea a me ka mālama ʻana i ka ʻala, ʻo ia kekahi o nā mea hoʻohana maʻamau anti-penetration composite film substrates, akā ʻaʻole maikaʻi ke kūpaʻa corona.
