Nā Hiʻohiʻona a me nā Hoʻohana o nā Mea Plastika PET

Hoʻolauna i nā mea plastik PET

ʻO ka palaki PET (Polyethylene Terephthalate) kahi thermoplastic hana kiʻekiʻe a maikaʻi hoʻi i ʻike ʻia no kona ikaika, ka moakāka, a me ka hiki ke hana hou ʻia. Hoʻohana nui ʻia i loko o nā ʻoihana hoʻopili, nā mea uila, a me nā kaʻa, ʻo ka mea PET kahi koho kiʻekiʻe no nā noi e pono ai ka lōʻihi a me ka moakāka. Ma ʻO HSQY Plastic Group , hāʻawi mākou i kiʻekiʻe nā pepa aniani PET a me nā huahana i hoʻopilikino ʻia i kāu mau pono. Ke nānā nei kēia ʻatikala i ke ʻano, nā hiʻohiʻona, a me nā noi o nā mea plastik PET..

He aha ka plastik PET?

ʻO ka palaki PET , a i ʻole Polyethylene Terephthalate, he polymer thermoplastic i ʻike nui ʻia ʻo polyester resin. Loaʻa iā ia ʻo PET a me kāna ʻano PBT (Polybutylene Terephthalate). ʻO ke ʻano molekala symmetrical kiʻekiʻe o PET e hāʻawi i nā waiwai hana kiʻiʻoniʻoni a me ka hoʻoheheʻe ʻana, e kūpono ia no ka hoʻopili ʻana a me nā noi ʻoihana.

ʻAno a me nā Waiwai Plastik PET

He kūlike loa ke ʻano molekala o ka mea PET me kahi kuhikuhi kristal ikaika, e hāʻawi ana i kona mau waiwai nui:

• ʻIke Moakaka : Hāʻawi ka Amorphous PET i ka moakaka maikaʻi loa, kūpono no ka hoʻopili ʻana.

• Ke kūpaʻa : Ke kūpaʻa kiʻekiʻe o ka kolo ʻana, ke kūpaʻa i ka luhi, a me ka paʻakikī ma waena o nā thermoplastics.

• Ke Kū'ē ʻana i ka ʻAʻahu : ʻO ka ʻaʻahu haʻahaʻa a me ka paʻakikī kiʻekiʻe e hōʻoia i ka hana lōʻihi.

• Palekana Uila : Hana paʻa ma nā mahana like ʻole, ʻoiai ua kaupalena ʻia ke kūpaʻa ʻana o ka corona.

• Ke Kū'ē Kemika : ʻAʻohe mea ʻawahia, kūpaʻa i nā waikawa nāwaliwali a me nā mea hoʻoheheʻe organik, akā ʻaʻole i ka wai wela a i ʻole ka alkali.

• Ke Kū'ē i ke Aniau : Mālama i ke kūpaʻa i nā kūlana ʻino.

PET vs PBT a me PP: He Hoʻohālikelike

Hoʻohālikelike ka papa ma lalo nei i ka plastik PET me PBT a me PP (Polypropylene) e hōʻike i kona mau pono:

Nā Kūlana	PET Plastic	PBT	PP
Ka moakāka	Kiʻekiʻe (PET amorphous)	Waena	Haʻahaʻa a waena paha
Ke kū'ē wela	Kiʻekiʻe (a hiki i 250°C me ka hoʻoikaika ʻana)	Kiʻekiʻe	Waena (a hiki i ka 120°C)
Kumukūʻai	Kumukūʻai kūpono (ethylene glycol emi ke kumu kūʻai)	ʻOi aku ke kumukūʻai	Kūpono ke kumukūʻai
Ka maʻalahi	Kaulike, palupalu i ka wā i hoʻopili ʻia	ʻOi aku ka maʻalahi	Loaʻa ka maʻalahi
Nā noi	Nā ʻōmole, nā kiʻiʻoniʻoni, nā mea uila	Nā mea uila, nā ʻāpana kaʻa	Nā ipu, nā ʻōpala

Nā Hiʻohiʻona Hoʻonui ʻia o ka PET Laminated

Me nā mea hoʻohuihui nucleating, nā mea hoʻohuihui crystallizing, a me ka hoʻoikaika ʻana i ke aniani fiber, hāʻawi ka mea PET laminated i nā pono hou aʻe:

• Ke Kū'ē Wela Kiʻekiʻe : Kū i 250°C no 10 kekona me ka ʻole o ka hoʻololi ʻana, kūpono no nā mea uila i hoʻopaʻa ʻia.

• Ikaika Mechanical : ʻO ka ikaika kūlou o 200MPa a me ka modulus elastic o 4000MPa, like me nā plastics thermosetting.

• Ka Pono o ke Kumukūʻai : Hoʻohana i ka ethylene glycol haʻahaʻa ke kumu kūʻai i hoʻohālikelike ʻia me ka butanediol o PBT, e hāʻawi ana i ke kumukūʻai kiʻekiʻe.

Nā noi o nā mea plastik PET

Kākoʻo ka plastik PET i nā kaʻina hana hoʻoheheʻe like ʻole (hoʻoheheʻe ʻana i ka injection, extrusion, blow molding, etc.), e hiki ai ke hoʻohana i nā noi like ʻole:

• Pūʻolo : ʻO nā ʻōmole meaʻai, mea inu, mea hoʻonani, a me nā lāʻau lapaʻau; nā ʻili ʻili sterile ʻaʻohe mea ʻawahia.

• Nā mea uila : Nā mea hoʻohui, nā bobbins coil, nā hale capacitor, a me nā papa kaapuni.

• Kaʻa : Nā uhi o ka papa kuapo, nā ʻōwili hoʻā, a me nā ʻāpana o waho.

• Nā Lako Hana Mīkini : Nā kia, nā kāmela, nā hale pamu, a me nā pā bakena microwave.

• Nā Kiʻiʻoniʻoni a me nā Substrates : Nā lipine leo, nā lipine wikiō, nā disks kamepiula, a me nā mea hoʻokaʻawale.

Nā ʻAno Kūʻai Honua no ka Plastika PET

I ka makahiki 2024, ua hōʻea ka hana ʻana o honua ka plastik PET no nā ʻōpala a me nā noi ʻoihana ma kahi o 20 miliona tone , me ka piʻi ʻana o 4.5% i kēlā me kēia makahiki , i hoʻokele ʻia e ke koi i nā ʻōpala meaʻai, nā mea uila, a me nā ʻāpana kaʻa. ʻO kona hiki ke hana hou ʻia a me ke kumukūʻai kūpono e hoʻoulu ai i ka ulu ʻana, ʻoi aku hoʻi ma ʻEulopa a me Asia-Pākīpika.

Nā nīnau i nīnau pinepine ʻia e pili ana i ka PET Plastic

He aha ka palaki PET?

ʻO PET (Polyethylene Terephthalate) kahi polymer thermoplastic i hoʻohana ʻia no ka hoʻopili ʻana, nā mea uila, a me nā noi kaʻa ma muli o kona moakaka a me ka lōʻihi.

He aha nā mea plastik PET i hoʻohana ʻia?

Hoʻohana ʻia ʻo PET no nā ʻōmole meaʻai a me nā mea inu, nā ʻāpana uila, nā ʻāpana kaʻa, a me nā kiʻiʻoniʻoni no nā lipine a me ka insulation.

Hiki ke hana hou ʻia ka palaki PET?

ʻAe, hiki ke hana hou ʻia ʻo PET, hoʻohana nui ʻia i nā papahana hoʻopili a me nā papahana hana hou.

Pehea e hoʻohālikelike ai ʻo PET me PBT?

Hāʻawi ʻo PET i ka transparency kiʻekiʻe a me ke kumukūʻai kūpono, ʻoiai ʻoi aku ka maʻalahi o ka PBT ma muli o kona ʻano molekala.

He palekana anei ka palaki PET no ka hoʻopili ʻana i ka meaʻai?

ʻAe, ʻaʻohe mea ʻawahia ʻo PET a palekana no ka hoʻopili ʻana i ka meaʻai, hoʻohana nui ʻia no nā ʻōmole a me nā ʻōpala sterile.

No ke aha e koho ai i ka HSQY Plastic Group?

Hāʻawi ʻo HSQY Plastic Group i nā mea plastik PET kiʻekiʻe , me Nā pepa aniani PET a me nā huahana i hoʻoheheʻe ʻia no ka hoʻopili ʻana, nā mea uila, a me nā noi kaʻa. Hoʻomaopopo kā mākou poʻe loea i nā hoʻonā kiʻekiʻe a kūpono hoʻi i kūpono i kāu mau pono.

E kiʻi i kahi ʻōlelo kūʻai manuahi i kēia lā! E kāhea mai iā mākou e kūkākūkā i kāu papahana, a e hāʻawi mākou i kahi ʻōlelo kūʻai hoʻokūkū a me ka manawa.

E noi i kā mākou ʻōlelo maikaʻi loa

Hopena

palaki PET , kūpono no ka hoʻopili ʻana, nā mea uila, a me nā noi kaʻa. Me kona moakaka, ikaika, a me ke kumukūʻai kūpono, he koho kiʻekiʻe ia ma nā ʻoihana like ʻole. He mea hana hou, hiki ke hana hou ʻia, a paʻa hoʻi ka ʻO HSQY Plastic Group kāu hoa hilinaʻi no kiʻekiʻe nā mea PET . E kāhea mai iā mākou i kēia lā e ʻike i ka hopena kūpono no kāu mau pono.
