Nā koʻokoʻo PTFE TEFLON
ʻO ka mea PTFE (i ʻike ʻia ma ke ʻano kemika ʻo Polytetrafluoroethylene, i kapa ʻia ʻo Teflon) he fluoropolymer semi crystalline me nā ʻano kūikawā he nui. Loaʻa i kēia fluoropolymer ke kūpaʻa wela kiʻekiʻe loa a me ke kūpaʻa kemika, a me kahi kiko heheʻe kiʻekiʻe (-200 a +260°C, pōkole a hiki i 300°C). Eia kekahi, loaʻa i nā huahana PTFE nā waiwai paheʻe maikaʻi loa, ke kūpaʻa uila maikaʻi loa a me kahi ʻili ʻaʻole e pipili. Eia naʻe, he ʻokoʻa kēia i kona ikaika mechanical haʻahaʻa, a me ke kaumaha kikoʻī kiʻekiʻe i hoʻohālikelike ʻia me nā plastics ʻē aʻe. I mea e hoʻomaikaʻi ai i nā waiwai mechanical, hiki ke hoʻoikaika ʻia nā plastics PTFE me nā mea hoʻohui e like me ke aniani fiber, carbon a i ʻole keleawe. Ma muli o kona ʻano, hoʻokumu pinepine ʻia ʻo Polytetrafluoroethylene i nā huahana semi-finished me ka hoʻohana ʻana i kahi kaʻina hana compression a laila mīkini ʻia me nā mea ʻoki/mīkini.

ʻO ke koʻokoʻo PTFE paʻa keʻokeʻo / koʻokoʻo teflon
ʻO ke koʻokoʻo PTFEhe huahana maikaʻi loa nō hoʻi no ka hoʻohana ʻana i loko o ka ʻoihana kemika ma muli o kona
ka hiki ke hana me nā waikawa ikaika a me nā kemika a me nā wahie a i ʻole nā kemika petrochemical ʻē aʻe

Pepa Hoʻoheheʻe ʻia PTFE / Papa Teflon
Pepa Polytetrafluoroethylene (Pepa PTFE) ma o ka polymerization hoʻokuʻu ʻia o ka hoʻoheheʻe ʻana o ka PTFE resin. Loaʻa iā ia ke kūpaʻa kemika maikaʻi loa i nā plastics i ʻike ʻia a ʻaʻole e ʻelemakule. Loaʻa iā ia ke coefficient friction maikaʻi loa i nā mea paʻa i ʻike ʻia a hiki ke hoʻohana ʻia ma -180 ℃ a i +260 ℃ me ka ʻole o ka ukana.

PEPA PAʻA PTFE (PEPA TEFLON)
Pepa PTFELoaʻa i nā nui like ʻole a me nā mānoanoa mai 1 a 150 mm. ʻO ka laulā mai 100mm a 2730mm, ua hoʻoneʻe ʻia ka ʻili Skived mai nā poloka PTFE nui (poepoe). Hana ʻia ka pepa PTFE i hoʻoheheʻe ʻia me ke ʻano Molding e loaʻa ai ka mānoanoa mānoanoa.
