PET - Polyethylene terephthalate

ʻO ka mea PET (ʻike ʻia ʻo polyethylene terephthalate) he polyester me kahi kiʻekiʻe kiʻekiʻe a hana ʻia e Ensinger i nā ʻano kumu kūʻai maʻamau no ka mīkini.Loaʻa ka PET ma ke ʻano he thermoplastic amorphous a semi crystalline.ʻO nā hiʻohiʻona o ke ʻano amorphous o PET polymer he ʻike kiʻekiʻe, akā ʻoi aku ka haʻahaʻa o nā mea mechanical e like me ka ikaika tensile, a me nā hiʻohiʻona haʻahaʻa haʻahaʻa haʻahaʻa.Eia nō naʻe, ʻaʻole hana ʻo Ensinger i ka mea PET e hoʻopau i ka hapa nui i loko o nā hue a i ʻole ka pahu.ʻO nā waiwai maʻamau o ka semi crystalline terephthalate a Ensinger i hana ai he paʻakikī, ʻoʻoleʻa, ikaika, ʻano hoʻoheheʻe maikaʻi a me nā lole haʻahaʻa (e hoʻohālikelike ʻia me POM i nā wahi maloʻo a maloʻo).Ua kapa ʻia kēia mea ʻo PET-P plastic, akā he ʻano ʻōlelo kahiko kēia no ka mea PET i kēia lā.

Ma muli o kona ikaika creep maikaʻi, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me ke kūpaʻa o ka dimensional koʻikoʻi, kūpono loa ka mea plastik PET no nā noi kahi e pono ai nā ʻāpana paʻakikī a me nā koi kiʻekiʻe e pili ana i ka pololei o ka dimensional a me ka maikaʻi o ka ʻili.Kākoʻo nā waiwai wela o PET i ke kūpaʻa wela maikaʻi a me ke kūpaʻa dimensional.

NA WAIWAI PETA A ME NA HOIKE
Hāʻawi nā mea PET:
● ikaika kiʻekiʻe
● Kiʻekiʻe rigidity a paakiki
● Haʻahaʻa haʻahaʻa loa
● Kūleʻa maikaʻi ke kolo
● Haʻahaʻa sliding friction a me ka sliding lole
● Kū'ē i ka hydrolysis (a hiki i +70 °C)
● ʻAʻole kūpono no ka hoʻopili ʻana me ka media i loaʻa >50% ka waiʻona
● Kūʻē kemika maikaʻi i nā ʻakika
● Adhesion maikaʻi a me ka hiki ke kuʻi

NA MEA HANA PILI
ʻO ka inoa kālepa Ensinger no nā hoʻololi PET ʻo TECAPET a i ʻole TECADUR PET.Hāʻawi ʻo Ensinger i kēia mau hoʻololi i ka Polyester:
● TECAPET - Hoʻololi ʻia ʻo PET no ka hoʻomaikaʻi ʻana i ka mīkini
● TECAPET TF - Hoʻololi ʻia ka PET me ka PTFE no ka maikaʻi o ka lole
● TECADUR PET - ka helu PET i hoʻololi ʻole ʻia
Hāʻawi ʻo Ensinger i ka PET ma ke ʻano o:
● koʻokoʻo plastik PET
● Pepa plastik PET
