PTFE/FEP vs Ultem® / PEI (polyetherimide) Mīkini
ʻO Ultem® / PEI (polyetherimide) he polymer amorphous ikaika loa me ka wela maikaʻi a me ka pale ahi (e lawe ana i ka helu flammability o 94-V-0) me ka liʻiliʻi o ka uahi.Hana mau ia i ka 340 ° F, e ʻoi aku ka maikaʻi ma mua o nā plastic commodity e like me Nylon a me Delrin®.ʻO ka PTFE he o ...Heluhelu hou aku -
ʻO ka PTFE a me ka Silicone
ʻO nā silikoni, ʻike ʻia hoʻi he polysiloxanes, he mau polymers e komo pū ana me nā pūhui inert, synthetic i hana ʻia me nā ʻāpana hou o ka siloxane, ʻo ia ke kaulahao o nā ʻātoma silikona a me nā ʻātoma oxygen, i hui pinepine ʻia me ke kalapona a/a i ʻole hydrogen.He mea maʻamau lākou i ka wela a me ka rubber-like...Heluhelu hou aku -
ʻO ka PTFE me ka ʻakika Perfluorooctanoic (PFOA)
ʻO ka waika Perfluorooctanoic (PFOA) (conjugate base perfluorooctanoate), i ʻike ʻia ʻo C8, he waika carboxylic perfluorinated synthetic a me ka fluorosurfactant.ʻO kekahi noi ʻoihana e like me ka surfactant i ka polymerization emulsion o nā fluoropolymers.Ua hoʻohana ʻia i ka hana ʻana i kēlā prom ...Heluhelu hou aku -
PTFE vs Rubber
He keʻokeʻo ka PTFE ma ke ʻano.No laila he hua'ōlelo redundant kēlā.ʻO nā ʻano polymer ʻē aʻe e like me FEP a me PFA ʻoi aku ka translucent;ʻaʻole keʻokeʻo.ʻOi aku ka palekana o ka PTFE ma mua o kāu elastomer automotive e like me neoprene a me EPDM.ʻO ia ka "ʻoi aku ka maikaʻi."E hoʻohaʻahaʻa maikaʻi ka Rubber ma mua o ka fluor...Heluhelu hou aku
