Kaʻina Hana Kiʻiʻoniʻoni BOPET: He Manaʻo

ʻO ke kiʻiʻoniʻoni BOPET, i ʻike ʻia he biaxially oriented polyethylene terephthalate, he kiʻiʻoniʻoni polyester i hana ʻia e ka hoʻolōʻihi ʻana i ka polyethylene terephthalate (PET) ma kāna mau ʻaoʻao mua ʻelua e hana i kahi kiʻiʻoniʻoni loea.

Ua hoʻomohala ʻia e ka hui Pelekane ICI i nā makahiki 1950.

Loaʻa iā ia nā pōmaikaʻi he nui ka ikaika tensile kiʻekiʻe, kemika a me ka dimensional stability, transparency, reflectivity, gas and aroma barrier properties, a me ka uila insulation.

Ma hope o nā makahiki o ka hoʻomohala ʻana, ua ulu ka huahana mai ka kiʻiʻoniʻoni hoʻokaʻawale hoʻokahi i ka kiʻi capacitor o kēia manawa, kiʻi paʻi kiʻi, kahi kiʻiʻoniʻoni insulating photosensitive, etc.

Hiki i kona mānoanoa mai 4.5um a 350 μm.

Ua hoʻomohala ʻia kāna kaʻina hana mai ka hana ʻana i nā kīʻaha kīʻaha maʻalahi a hiki i ka hoʻolōʻihi ʻana a me ka hoʻolōʻihi ʻia bidirectional.

Ua ulu pū kona ʻano huahana mai kahi kiʻiʻoniʻoni palahalaha a hiki i ke kiʻiʻoniʻoni coextruded multilayer, kiʻiʻoniʻoni hoʻoikaika ʻia, a me ke kiʻiʻoniʻoni i uhi ʻia.

Ua lilo ka kiʻiʻoniʻoni polyester i kekahi o nā ʻano kiʻiʻoniʻoni wikiwiki i ka mākeke.

ʻO Dehui FIlm kekahi o nā mea hoʻolako kiʻiʻoniʻoni bopet ma Kina. I kēia manawa, hana nui mākou iā lākou ma ke kaʻina hana ʻelua-ʻaoʻao ʻelua. Me ka hoʻonui ʻana o kāna leo noi, ke piʻi aʻe nei nā koi o nā kiʻiʻoniʻoni polyester. Ke koi nei iā mākou e hoʻomaikaʻi i ka maikaʻi a hoʻonui i ka hopena.

Kaʻina hana kiʻiʻoniʻoni BOPET

I kēia manawa, e hoʻolauna kākou i ke kaʻina hana kiʻiʻoniʻoni bopet. Penei ke kaʻina hana maʻamau:

ʻO ka hoʻomaloʻo ʻana o ka resin PET → hoʻoheheʻe extrusion → hoʻolōʻihi lōʻihi o nā lau mānoanoa → hoʻolōʻihi ʻia → wili ʻana → ʻoki a me ka hoʻopili ʻana → ka hana hohonu.

PET hehee-extruded hoolei pepa

Ma hope o ka hoʻoheheʻe ʻia a me ka plasticized i ka resin PET maloʻo, a laila hui pū ʻia e nā kānana koʻikoʻi a maikaʻi a me ka mixer static, lawe ʻia ia i ke poʻo mīkini e ka mīkini mīkini. A laila hoʻoluʻu ʻia e ka huila kinai i loko o nā ʻāpana mānoanoa no ka hoʻohana ʻana.

Extrusion o biaxially kikoo

ʻO ke kiʻi ʻoniʻoni ʻoniʻoni ʻo PET Biaxial (direction) e hoʻolōʻihi i ka kiʻiʻoniʻoni a i ʻole ka pepa i hoʻokuʻu ʻia mai ka extruder i kahi mahana. Ma ka longitudinal a me ka transverse kuhikuhi e hana i ke kaulahao mole.

ʻO ka maka aniani e hoʻoholo ʻia e kuhikuhi ʻia, a laila lawe ʻia ka mālama ʻana i ka wela i ka hihia o ka hoʻopololei.

ʻO ke kiʻi ʻoniʻoni biaxially, ma muli o ka orientation o nā ʻāpana molekala, hoʻomaikaʻi i ka crystallinity.

No laila hiki iā ia ke hoʻonui nui i ka ikaika tensile, tensile elastic modulus, ikaika hopena, ikaika waimaka, hoʻomaikaʻi i ke kūpaʻa anuanu, transparency, airtightness, Electrical insulation, a me ka nani.

Hoʻohana ka hapa nui o ka kiʻiʻoniʻoni palahalaha i ke kaʻina hana hoʻolōʻihi biaxial.
