mkulu makina katundu PEI- Osadzaza, GF, CF kwa mafakitale katundu chivundikirocho

Polyetherimide (PEI) ndi amorphous, amber-to-transparent thermoplastic yokhala ndi mawonekedwe ofanana ndi PEEK yapulasitiki.Poyerekeza ndi PEEK, PEI ndiyotsika mtengo, koma ndiyotsika mphamvu komanso kutentha koyenera.Chifukwa cha zomatira zake komanso kukhazikika kwamankhwala zidakhala chida chodziwika bwino cha bedi la osindikiza a FFF 3D.

Kutentha kwa galasi la PEI ndi 217 ° C (422 ° F).Kuchuluka kwake kwa amorphous pa 25 °C ndi 1.27 g/cm3(.046 lb/in³).Amakonda kupsinjika ndi kusweka kwa zosungunulira za chlorine.Polyetherimide imatha kukana kutentha kwambiri ndi mphamvu zamagetsi zokhazikika pama frequency osiyanasiyana.Zida zamphamvu izi zimapereka mphamvu zabwino kwambiri zolimbana ndi mankhwala komanso ma ductile oyenera kugwiritsa ntchito zosiyanasiyana, ngakhale zomwe zimaphatikizapo kukhudzidwa ndi nthunzi.
