PEEKhe thermoplastic i hana maikaʻi ʻia ma lalo o ka ʻike ʻana i nā wela kiʻekiʻe a me nā wahi kemika.ʻO ka hiki i kēia mea ke mālama i kona mau waiwai kino a kū i nā mahana a hiki i 480 degere F he mea waiwai nui ia i kūpono no nā ʻano hoʻohana like ʻole me ka pani ʻana i ke kila kila ma nā wahi paʻakikī.He ʻano māmā ia i ke kila a me ka alumini a me ke kūpaʻa lole kiʻekiʻe me ka ʻole o ka lubrication.
PTFEhe polymer crystalline me kahi helu heheʻe ma kahi o 621° F (327° C).He 2.13 a 2.19 gm/cc ka nui.He kūʻokoʻa ko PTFE i nā kemika.He haʻahaʻa a paʻa kona mau dielectric (2.1) a paʻa ma waena o ka laulā ākea a me ke alapine.Loaʻa iā PTFE nā waiwai mechanical pono mai nā mahana cryogenic ma 500 ° F (280 ° C) mau wela lawelawe mau.ʻOi aku ka haʻahaʻa o kona coefficient o friction ma mua o nā mea ʻē aʻe.Loaʻa iā ia kahi pae oxygen kiʻekiʻe.
Hoʻohālikelike o ka PEEK a me ka Polymer PTFE/FEP Waiwai Waiwai
Nā mea hoʻohana waiwai:
* PEEK: Nā Bearings; Nā Pumps; Nā ʻāpana Piston; Hoʻomoe Uila.*PTFE: Hoʻopili ʻana i nā kelepona; ʻAʻole lubricated bearings; O-rings; Sila; Capacitors; Semiconductor manufacturing; Nā ʻāpana uila wela kiʻekiʻe; Gaskets; Nā ʻāpana valve.
Mea waiwai:
*PEEK: Kūleʻa haʻahaʻa kiʻekiʻe; Ka hoʻohaʻahaʻa haʻahaʻa haʻahaʻa; Ke kūʻē kemika koʻikoʻi; Ka helu haʻahaʻa o ka friction; ʻO nā hiʻohiʻona maikaʻi loa; Machinability.*PTFE: ʻO nā waiwai dielectric maikaʻi loa; ʻAʻole i ka nui o nā kemika; ʻO ka wela kiʻekiʻe a me ke kūpaʻa kemika; Haʻahaʻa haʻahaʻa haʻahaʻa o ka friction; ʻOi aku ka maikaʻi o ka pale ʻana i ka radiation; Zero moisture absorption; Pili ʻole i ka mana pinepine; Machinability.
