I-PTFE/FEP vs Ultem® / PEI (polyetherimide) Machining

I-Ultem® / PEI (i-polyetherimide)i-amorphous polymer enamandla kakhulu enokushisa okuhle kakhulu nokumelana nelangabi (ephethe isilinganiso sokuvutha esingu-94-V-0) esikhipha intuthu encane.Isebenza ngokuqhubekayo ukuya ku-340° F, iyenze ibe phezulu kunoplastiki bempahla njengeNylon neDelrin®.

I-PTFEyasungulwa ekuqaleni ukuze isetshenziswe kwizicelo ze-aerospace kodwa ngokushesha yathola ikhaya ezindaweni eziningi zezimboni.Izici eziyingqayizivele ze-PTFE zifaka: ukungabi namandla kwamakhemikhali (amakhemikhali ambalwa kakhulu angayihlasela), i-coefficient ephansi kakhulu yokungqubuzana (akukho lutho olunganamathela kumpahla nganoma yimaphi amandla), ukumelana nokushisa okuphezulu (okukwazi izinga lokushisa lesevisi engu-500° F) futhi iwusizo kakhulu izindawo zokushisa ezibandayo.

I-Ultem® / PEI (i-polyetherimide) iyi-polymer e-amorphous enamandla aphezulu enokushisa okuhle kakhulu nokumelana nelangabi (ephethe isilinganiso sokuvutha esingu-94-V-0) esikhipha intuthu encane.Isebenza ngokuqhubekayo ukuya ku-340° F, iyenze ibe phezulu kunoplastiki bempahla njengeNylon neDelrin®.I-Ultem® iyisixazululo esifanelekile sezinhlelo zokusebenza ezidinga amandla aphezulu kanye nekhono lokumelana namazinga okushisa aphezulu.Umkhiqizo futhi ufanela izinhlelo zokusebenza ezidinga izakhiwo ze-dielectric ezingaguquki ngaphezu kwamafrikhwensi amaningi.I-Ultem® imelana ne-hydrolysis futhi imelana kakhulu nezixazululo ezine-asidi futhi iyakwazi ukubekezelela imijikelezo ye-autoclaving ephindaphindwayo, njengokuvala inzalo okuphindaphindiwe kwemishini yezokwelapha engasetshenziswa kabusha.I-Ultem® isetshenziswa kakhulu ku-elekthronikhi ngenxa yokumelana kwayo ne-arc okuhle nokungaguquki kwe-dielectric.Ezinye izinhlelo zokusebenza ezijwayelekile zifaka izinsimbi zokuhlaziya kanye nezingxenye zesakhiwo ezidinga amandla aphezulu kanye nokuqinile emazingeni okushisa aphakeme.

Ukuqhathaniswa kwe-polymer PTFE/FEP kanye ne-Ultem® / PEI (polyetherimide) Amanani Ezakhiwo
