ETFE (kana Ethylene tetraflurorethylene) ipurasitiki yakagadzirwa nefluorine, yakashongedzerwa nepamusoro pekunyunguduka uye yakanakisa kemikari, yemagetsi uye yakakwirira simba nemwaranzi rekudzivirira property.PTFE (kana polytetrafluroethylene) is fluorocarbon solid.Kushanda se hydrophobic, kwete mvura kana mvura-yakavakirwa zvinhu zvakanyorova PTFE.PTFE inoderedza kukweshera, kupfeka uye nekudaro mashandisirwo emagetsi emapombi sezvo iine imwe yakaderera coefficients yekukweshera kune chero yakasimba.
Zvinhu zvinonyanya kushandiswa kushandiswa kusimbisazve pombi ndeye PTFE uye ETFE polima.
PTFE inovakwa kubva kucarbon uye fluorine maatomu nepo ETFE inovakwa kubva kucarbon, fluorine uye haidrojeni.Kupa zvakanakira kushandisa ese ari maviri.
Simba rekusimba reETFE rinogona kunge rakaita 38% yakakura kupfuura PTFE, zvinoreva kuti ETFE zvinhu zvinogona kuiswa pasi pemamiriro ekushanda akaoma kupfuura shamwari yayo.
Ichi ndicho chikonzero mapombi emakemikari mazhinji achipihwa muETFE sezvo chiri chinhu chakasimba chejekiseni rekuumba maitiro avanopinda.
Zvisinei PTFE ine coefficient of friction pachikamu chimwe muzvitatu cheETFE ichiita kuti inyatsokodzera kana kuyerera kwepamusoro kuchidiwa sezvo ichibatsira kuderedza friction yepombi Losses.Thermal properties yezvinhu zvose zviri zviviri zvakare musiyano wakakosha ... PTFE inogona kusvika pakupisa kwe327c. nepo ETFE inogona kusvika pakupisa kwakanyanya kwe267c.
Iyi nhanho yakakosha pakusarudza iyo yakanyanya kufanira pombi;kana iyo application inoda kupomba inogona kusvika chero padyo netembiricha idzi zviri nani kusarudza PTFE sezvo zvese zviri zviviri zvinyoro nyoro pedyo nepamusoro petembiricha nzvimbo.
Uyezve, PTFE ine Limiting Oxygen Index (iyo shoma muzana yehuwandu hweokisijeni apo polima ichapisa) yakakura kudarika 95% nepo ETFE iri pakati pe30-36%, zvichireva kuti PTFE inofanira kuonekwa munzvimbo dzakakwirira dzeokisijeni.
