PTFEuye TFM inoshandiswa kuita mabhero mukunyanya kuomarara kwemaitiro - kunyanya organic compounds, asidhi, uye munyu - pamwe nekupisa kwakanyanya uye kuchena kwakanyanya.Iwo ese ari maviri anoratidza maitiro asina-tsvimbo, uye ane hupamhi hwakafanana hwetembiricha yekushandisa.Nekudaro, pane misiyano yakakura pakati pavo, nekuti TFM inosanganisa akanakisa maitiro eese ari maviri PTFE nePFA.TFM ndiyo mabhero zvinhu zvesarudzo kana iwe uchida yakanyanya kuderera gasi kupera, hupenyu hurefu hwekuneta, uye kupera kwepamusoro kwakapfava.
Modified PTFE ikemikari yakagadziridzwa vhezheni yePTFE ine hunyanzvi hutsva mukuwedzera kune hunhu hunoenderana nemhandara yePTFE zvinhu.
Yakagadziridzwa PTFE ine aya matsva kana akagadziridzwa maitiro pamusoro peyakajairwa PTFE:
Chikamu chepamusoro chakatsetseka, uye hachina porous - zvikamu zvinogara zvakachena sezvo zvisingaite zvekuteya zvinosvibisa Low micro-void content zvinopa goho rakagadziridzwa permeation Upenyu hurefu hunoshanduka kupfuura PTFEKuwedzera kuomarara & kunatsiridza kukambaira kusimba Simba re dielectric rinopa simba repamusoro-voltage insulationFusible / Weldable (Utilizing maitiro akasiyana-siyana ekupisa welding ane mwero kumanikidzwa)Mienzaniso yeContainers & Tubes yakagadzirwa uchishandisa APT's Modified PTFE Fusing & Machining process.
PTFE inomirira Polytetrafluoroethylene, fluorocarbon thermoplastic yakawana kushandiswa kwakakura mumainjiniya maapplications uye inonyanya kuzivikanwa nekuve neiyo yakaderera coefficient yekukwesha chero kwakasimba.Iyo inozivikanwa zvakare sepolymer, Dyneon TM, 1,1,2,2-tetraflouroethene kana 1,1,2,2-tetraflouroethylene.
Sezvatotaurwa, PTFE ndeimwe yemakemikari inert polymers inowanikwa (Chemical Resistance Chart).Iine tembiricha inoenderera mberi yekushandiswa kubva -200 ° C kusvika 250 ° C uye inoshingirira kubatwa nemvura.Pamusoro pezvo, ine anti-adhesive maitiro ayo anoramba kuvakwa kwezvakaoma, zvichiita kuti zvive nyore kuCIP (Yakachena Munzvimbo).Muchokwadi, kune akasiyana mamakisi ePTFE ayo akatenderwa neFDA.
Yakashandurwa PTFEinonzi kemikari inonzi polytetrafluoroethylene, uye nezita rekutengeserana Polyflon.Musanganiswa unonakidza wezvivakwa zvePTFE nePFA (Perfluoroalkoxy), inozivikanwa nehukuru hwemakina.
Kufanana nePTFE, TFM ine makemikari inert uye ine mutsara wakafanana wekuenderera mberi kwekushisa kwekushandisa, pamwe chete nekudzivirira kwakafanana pakutorwa kwemvura.Iyo zvakare inochengeta yakawanda yePTFE isiri-tsvimbo maitiro.
TFM zvakare ine yakakwira zvishoma chitubu mwero, asi zvinoonekwa zvirinani kuneta zvivakwa uye inoratidza zvirinani kudzoreredza kushushikana.Mukuwedzera, zviri nyore kusungira pane PTFE uye inorema zvishoma.TFM zvakare inopokana kune zvese embrittlement uye kuchembera.
Chimwe chinhu chinoita kuti TFM ive yakakosha ndeye density yeiyo molecular chimiro.Izvi zvinoguma nekudzika kwakanyanya kwegasi kupindira kwehukobvu hwakafanana hwezvinhu kana uchienzaniswa nePTFE.Hunhu uhu hwakakosha zvakanyanya kana hukashandiswa munzvimbo ine ngura zvakanyanya.Iine dense molecular chimiro, TFM inopawo yakapfava pamusoro pekupedzisira iyo PTFE.Zvakare, sePTFE, kune akasiyana mamakisi eTFM ayo akatenderwa neFDA.
