Chii chinonzi PEEK?
Polyether ether ketone(PEEK) ndeye thermoplastic inonhuhwirira polymer zvinhu.Iyo imhando yeakakosha einjiniya epurasitiki ane mashandiro akanaka, kunyanya kuratidza kusimba kwakasimba kwekupisa, friction resistance uye dimensional kugadzikana.Inoshandiswa zvakanyanya mune aerospace, mauto, mota, mushonga uye mamwe minda.
Basic PEEK performance
PEEK ine high mechanical simba, high temperature resistance, impact resistance, flame retardant, acid and alkali resistance, hydrolysis resistance, abrasion resistance, kuneta kuramba, radiation resistance uye kunaka kwemagetsi.
Ndiyo giredhi repamusoro rekudzivirira kupisa mumapurasitiki einjiniya akakosha.
Tembiricha yebasa renguva refu inogona kubva -100 ℃ kusvika 260 ℃.
PEEK epurasitiki mbishi zvinhu zvine epamusoro dimensional kugadzikana maitiro.Mamiriro ekunze ane tembiricha yakakura uye humidity shanduko ine zvishoma pakukura kwezvikamu zvePEEK, uye iyo PEEK jekiseni rekuumba shrinkage rate idiki, izvo zvinoita kuti kurongeka kwezvikamu zvePEEK zvikwire zvakanyanya kupfuura zvemapurasitiki akajairwa, anogona kusangana nezvinodiwa zve. high dimensional kururama pasi pemamiriro ekushanda.
PEEK ine yakakurumbira kupisa - inodzivirira hydrolysis maitiro.
Munharaunda yekushisa kwepamusoro uye kunyura kwemvura yakadzika zvakanyanya, zvakafanana nenylon nemamwe mapurasitiki nekuda kwekutora mvura uye ukuru hwekuchinja kuri pachena.
PEEK ine kusimba kwakanyanya uye kuramba kuneta, inofananidzwa nealloys, uye inogona kushandiswa kwenguva yakareba mukuda nharaunda dzekushanda.Kutsiva simbi, aluminium, mhangura, titanium, ptFE uye zvimwe zvinhu zvepamusoro-soro, kuvandudza mashandiro emuchina panguva imwechete inoderedza zvakanyanya mutengo.
PEEK ine chengetedzo yakanaka.Iwo UL bvunzo mhinduro dzezvinhu zvinoratidza kuti PEEK's flame retardation index iGiredhi V-0, inova giredhi rakakwana rekudzosa moto.PEEK's combustibility (kureva, huwandu hwehutsi hunogadzirwa panguva yekupisa) ndiyo yakaderera pane chero plastiki.
PEEK's gasi kusakwanisa (kusangana kwegasi inogadzirwa kana yakaora pakupisa kwakanyanya) zvakare yakaderera.
Nhoroondo ye PEEK
PEEK ndicho chinhu chiri pamusoro pepiramidhi yepurasitiki, uye makambani mashoma ari munyika akagona maitiro epolymerization.
PEEK yakagadzirwa neICI muma1970s.Nekuda kweayo akatanhamara emakanika zvivakwa uye zvivakwa zvekugadzirisa, yakave imwe yeakanakisa einjiniya mapurasitiki.
Tekinoroji yekuChina yePEEK yakatanga kuma1980s.Mushure memakore ekutsvagisa kwakasimba, Jilin University yakagadzira iyo PEEK resin synthesis process ine yakazvimirira kodzero yepfuma.Haisi chete kuita kwechigadzirwa kwasvika padanho rePEEK yekunze, asi zvakare zvigadzirwa nemidziyo zvese zviri muChina, zvichinyatso kudzikisa mutengo wekugadzira.
Parizvino, indasitiri yeChina yePEEK yakura, iine mhando yakafanana uye inobuda sevagadziri vekunze, uye mutengo wakadzikira zvakanyanya kupfuura musika wepasirese.Chinoda kuvandudzwa hupfumi hwakasiyana hwePEEK.
Victrex yaive chikamu cheBritish ICI kusvika yabviswa.
Yakave yekutanga nyika kugadzira PEEK.
Kushandiswa kwePEEK
1. Zvishandiso zvemuchadenga: kutsiva aluminium uye mamwe masimbi kune zvikamu zvendege, zveroketi bhatiri slots, mabhaudhi, nzungu uye zvikamu zveroketi injini.
2. Kushandisa mundima yemagetsi: firimu rekudzivirira, chibatanidza, bhodhi redunhu rakadhindwa, chibatanidza chekushisa kwepamusoro, dunhu rakasanganiswa, cable coil skeleton, kuvhara kwekuvhara, nezvimwewo.
3. Zvikumbiro mumichina yemotokari: mabhengi emotokari, gaskets, seals, clutches, mabhureki uye air conditioning systems.Nissan, NEC, Sharp, Chrysler, GENERAL Motors, Audi, Airbus uye vamwe vakatanga kushandisa zvinyorwa muhuwandu hwakawanda.
4. Zvikumbiro munharaunda yezvokurapa: mapfupa ekugadzira, denture implant base, mishonga yezvokurapa inoda kushandiswa kakawanda.
