Polymer PTFE/FEP vs Vespel Mīkini

ʻO Vespel ka hōʻailona kūʻai o ka nui o nā plastics polyimide-based polyimide lōʻihi i hana ʻia e DuPont. ʻO Polytetrafluoroethylene (PTFE) he fluoropolymer synthetic o tetrafluoroethylene he nui nā noi.ʻO ka inoa inoa inoa maikaʻi loa o nā kumu hoʻohālikelike PTFE he polymer na Chemours.ʻO Chemours kahi spin-off o DuPont Co., nāna i ʻike i ka pūhui ma 1938.

Hoʻohālikelike o ka Polymer PTFE/FEP a me Vespel waiwai waiwai

Noi Mea

Polymer PTFE/FEP:ʻO nā mea hoʻonā kelepona; ʻAʻole lubricated bearings; O-rings; Sila; Capacitors; Hana semiconductor; Nā ʻāpana uila wela kiʻekiʻe; Gaskets; Nā ʻāpana valve.

Vespel:Hoʻohana nui ʻia kēia polymer hana kiʻekiʻe i ka aerospace, semiconductor a me ka ʻenehana halihali.Hoʻohui ia i ka pale wela, lubricity, dimensional stability, chemical resistance, a me ka creep resistance, e hoʻohana ʻia i loko o nā kūlana kūlohelohe a koʻikoʻi. a me ke kākoʻo crucible.He hana maikaʻi nō hoʻi ia i loko o nā hoʻoheheʻe ʻana, a hiki i nā mahana cryogenic haʻahaʻa loa.Eia nō naʻe, makemake ʻo Vespel e hoʻomoʻa i kahi wai liʻiliʻi, e hopena i ka manawa paʻa lōʻihi ke waiho ʻia i loko o kahi ʻūhā.

Mea Pono

PolymerPTFE/FEP:ʻO nā waiwai dielectric maikaʻi loa; ʻAʻole i ka hapa nui o nā mea 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.

Vespel:Ka hana mau a hiki i 600°F; ʻAʻohe mea hana mīkini kūikawā e koi ʻia; Paʻa paʻa; Hana ʻia ma nā PV kiʻekiʻe loa; ʻAʻole e lilo i palupalu a hiki i nā mahana subzero; Machinability.
