PTFE (PolyTetraFluoroEthylene) inonzi fluorocarbon-based polymer inozivikanwawo muindasitiri yese sezita rezita reDupont.polymer®.Vamwe vagadziri vakati wandei vanogadzira yavo mhando yePTFE iyo inogona kushandiswa sechinotsiva zvinhu.Iyi mhuri yefluoroplastic inopa mapurasitiki ane akakwira makemikari kuramba, yakaderera uye yakakwirira tembiricha kugona, kuramba kutonhora, kuderera, kuputika kwemagetsi uye kupisa, uye "kutsvedza."
PTFE yakazadzwa ne5% kusvika 10% mica inopa yakasarudzika musanganiswa wesimba uye dimensional kugadzikana pamwe neakanakisa kupfeka inosimudzira yekuwedzera tekinoroji.Ichi chigadzirwa chinopa kupfeka kwakanaka uye kugadzikana mukuwedzera kune FDA kutevedzera.
Fluorosint® musanganiswa wevaridzi umo inogadzirwa mica inosanganiswa nekemikari kuPTFE.Kubatana uku kunoguma mune zvivakwa zvisingawanzo kuwanikwa mune yakasimbiswa PTFE.Fluorosint® mamakisi anopa musanganiswa wakanakisa weakaderera frictional properties, dimensional kugadzikana, yakanakisa makemikari kuramba, uye kuenderera kwekushandisa tembiricha ye500°F (260°C).Kuenzaniswa nePTFE, ine yakakwira kutakura mutoro, 1/9 ye deformation pasi pemutoro, uye yakaderera coefficient yekuwedzera kupisa.
FLUOROSINT MIBAKAFluorosint® 500 ine kapfumbamwe kurwisa deformation pasi pemutoro pane isina kuzadzwa PTFE.Iyo coefficient of linear thermal expansion (CLTE) inosvika pakuwedzera kwealuminum uye i1/5 iyo yePTFE - kazhinji inobvisa matambudziko akakodzera uye ekubvisa.Iyo 1/3 yakaoma kupfuura PTFE, ine zvirinani kupfeka maitiro, uye inochengetedza yakaderera frictional properties.Fluorosint ® 500 zvakare haina-abrasive kune akawanda mating zvinhu.
Fluorosint® 207's isingaenzaniswi dimensional kugadzikana, yakanakisa inokambaira kuramba uye chena ruvara inoisa chinhu ichi kuti chishandire FDA yakadzorwa maapplication.Iyo haipindike muutsi uye inoenderana neFDA regulation 21 CFR 175.300.Kupfeka kwacho kuri 1/20 chiyero chePTFE pazasi 300°F (150°C).Iko kusanganiswa kwekuita kwakanaka kwemuchina uye yakasarudzika yakasarudzika kemikari uye hydrolysis kuramba, Fluorosint® 207 inovhura akawanda mikana yekushandisa mumaindasitiri ezvekudya, emishonga, uye ekurapa.
APPLICATIONS
- Magetsi uye anopisa ekudzivirira mapedhi pasi pekumanikidza mitoro
- Bearings, bushings
ZVAKANAKA
- Kuramba kwakanaka kupfeka
- Yakanakisa kemikari uye hydrolysis kuramba
