Vesapel ndiyo chiratidzo chehuremu hwenzvimbo dzakasimba kwazvo-performance-based mapurasitiki akagadzirwa naUPont.
Hunhu uye zvikumbiro
Velapel inonyanya kushandiswa muEerospace, Semiconductor, uye tekinoroji yekutakura. Inosanganisa kupisa kupokana, Lubricity, kudzikisira, kuramba kwemakemikari, uye kupokana kwekutya, uye kunogona kushandiswa mumamiriro ezvinhu anovenga uye akaomesesa.
Kusiyana nePlastics mazhinji, hazvibereki kupenya kwakakosha kunyange pakupisa kwakanyanya, izvo zvinoita kuti zvive zvinobatsira kuti zvinyoronyoro dzinotyisa dzinotyisa uye tsigiro inoverengerwa. Izvo zvakare zvinoitawo zvakanaka mumashandisirwo ezvipindurudzo, pasi kusvika kune yakaderera kwazvo cryogenic tembiricha. Nekudaro, velapel inowanzo kutora mashoma madiki emvura, zvichikonzera nguva refu pombi pakaiswa mune vacuum.
Kunyangwe paine polysmers kupfuura polyimide mune imwe yeaya midziyo iyi, kusanganiswa kwavo ndiko kwakanyanya mukana weVesel.
Thermophysical Properties
Velapel inowanzo shandiswa seyakagadziriswa zvinyorwa zvinyorwa zvekuyedza kuongorora maInstrulators, nekuda kwekubereka kwakanyanya uye kuwirirana kwezvinhu zvayo zvemitambo. Semuenzaniso, inogona kutsungirira kudzokorora kudzora kusvika mazana matatu
Magnetic Properties
Vespel inoshandiswa muhombe-resolution procution yeNMR spectroscopy yekunyepedzera kwekunyepedzera (1 9) 6 na20 ° C [6]) Tsika dzisina kunaka dzinoratidza kuti zvinhu zvese zviri zviviri zvadzinoita Diaggnetic. Kufananidza vhoriyamu yemagineti yemagineti yezvinhu zvakakomberedza NMR sampuli kune iyo yeiyo solvent inogona kuderedza kupatsanurana kwemagineti emagineti.
Kugadzirisa kwekugadzira zvikumbiro
Vesipel inogona kuongororwa nekugadzira zvakananga (df) uye isostatic kuumbwa (Basicument maumbirwo - mahwendefa, tsvimbo uye machubhu). Zvemhando dzeprotomy Zvekukura zvakanyanya
Mhando
Zvekushandisa zvakasiyana, mafambiro akakosha akasanganiswa / kuumbwa. Maumbirwo anogadzirwa nematanho matatu akajairwa:
kumanikidza kuumba (yemirazvo uye mhete);
Isoostatic kuumbwa (yetsvimbo); uye
zvakananga kugadzira (kwezvidimbu zvidiki zvikamu zvinogadzirwa mumavhoriyamu muhombe).
Zvikamu zvakananga-zvakaumbwa zvine kuderera maitiro ekuita pane zvikamu izvo zvakagadzirwa kubva mukumanikidza kubva kumisikidzwa-yakaumbwa kana isatatic maumbirwo. MaOstatic Maumbirwo ane isotropic yemuviri zvivakwa, nepo zvakaumbwa zvakaumbwa uye kuenderana kwakaumbwa maumbirwo ekuratidzira aunistotropic muviri.
Mimwe mienzaniso yeiyo standard polyimide makompones ndeiyi:
SP-1 mhandara polyimide
Inopa tembiricha yekushandisa kubva kuClyogenic kusvika 300 ° ° C (570 ° F), yakakwira plasma kuramba, pamwe ne UL chiyero cheiyo shoma yemagetsi uye inodanana. Ichi ndicho chisati chatangirwa chigadziko polyimide resin. Inopawo simba rakakwirira remuviri uye kuwedzera kwakanyanya, uye zvakanakisa zvemagetsi uye zvinopisa zvekusimbisa tsika. Muenzaniso: Vesel SP-1.
15% graphite nehuremu, sp-21
Yakawedzerwa kune base resin yekuwedzera kuparara uye yakaderedzwa kukakavara mune zvikumbiro zvakadai sebanda Iyi compound ine yakanyanya kunaka mechanices yeiyo graphiti-yakazadzwa-yakazadzwa-yakazadzwa, asi yakaderera pane iyo mhandara giredhi. Muenzaniso: Vesel SP-21.
40% graphite nehuremu, sp-22
Kune kusimbiswa kupfeka kupokana, kuparadzaniswa kwakadzika, kuvandudza kugadzikana kwemukati (yakaderera coefficient yekuwedzera kwekuwedzera), uye kugadzikana kurwisa oxidation. Muenzaniso: Vesipel SP-22.
10% ptfe uye 15% graphite nehuremu, sp-211
yakawedzerwa kune base resin yeiyo yakaderera coeff friction yekukakavara pamusoro pehuremu hwakasiyana. Iyo zvakare ine yakanakisa kupfeka kuramba kusvika 149 ° C (300 ° F). Chaizvoizvo zvinoshandiswa zvinosanganisira kutsvedza kana mutsara fani pamwe nekupfeka kwakawanda uye kupokana kunoshandisa zvakanyorwa pamusoro apa. Muenzaniso: Vesel SP-211.
15% moly-yakazara (molybdenum disulfide yakasimba lubricant), sp-3
Kuti urege kupfeka uye kupokana kupokana mucuum uye dzimwe nharaunda dzemahara-dzemahara apo graphite inova inowedzera. Chaizvoizvo zvinoshandiswa zvinosanganisira Zvisimbiso, Blain Bages, magiya, uye zvimwe zvipfeko zvekunze munzvimbo dzekunze, Ultra-yakanyanya-yakanyanya kuoma kana yakaoma gasi application. Muenzaniso: Vesel SP-3.
