Polyether ETone Ketone (Peek) Resin Inonyatsojeka Mapurasitiki ane zvakanakisa zvekuita, kuzvidzora kwakanyanya, kuzvidzora kwemakemikari, murazvo unodzora, murazvo unodzora, kupokana neeel, kurwisa kurwisa uye minda yekugadzirisa chikafu.

Peek resin yakatanga kushandiswa munda weAerospace, kutsiva aluminium uye zvimwe zvinhu zvesimbi kuti zvigadzire akasiyana siyana ndege.

Muindasitiri emagetsi Mota inoshandiswa zvakanyanya.

Peek Resin ndeye yakanaka emagetsi insulator, kudzvinyirira kwakanyanya uye humbowo hwepamusoro uye humwe hunhu hwekushanda kwemagetsi, zvichikwanisa kuita zvishoma nezvishoma nzvimbo dzepiri dzisiri dzepiri dzekushandisa. Kugadzira mapepa ekutakura kwekutakura kwemvura yehuchi, macves uye pombictor indasitiri, inowanzoshandiswa kugadzira mutakuri wemauto, magetsi emagetsi diaphragm uye akasiyana emidziyo yekubatanidza. Semi-semi-crystalline engineering purastics, peek insoluble mune yakaomeswa sulfutic acid kunze kweinongororo, zvikwangwani, zvisimbiso uye akasiyana emakemikari emakemikari, mavharuvhu uye zvikamu.

Peek Resin inogonawo kutsungirira kusvika kune zviuru zvitatu zvibodzwa zveAdoclaving pa134 ° C.4 , asi zvakare vane elasticity mwoluus iri padyo neiyo yepafupa remunhu arimo, rinobvumidza kusungwa kwemutumbi, saka resin rakakosha rekushandisa mumunda wekurapa, sezvazvinogona kushandiswa pachinzvimbo chesimbi mugadziri yemapfupa emunhu. Peek yakatanga kushandiswa mukuita kwekiriniki muna1999, uye kubvira panguva iyoyo zviuru gumi zvemamiriyoni zvigadziko zvakaiswa mumuviri wemunhu, uye yave iri yegoridhe yegoridhe mumunda wesango fusion. Mumakore achangopfuura, peek yakarumbidzwa se "zvinyorwa zvakanakira zvechizvarwa chinotevera chezvigadzirwa zvekurapa zviri pamutemo".
