Teflon yakakwirira inoshanda yakakosha coating ndeyeptfeseyakadzika resin ye fluorine coating, zita reChirungu reTeflon, nekuda kwemataurirwo, anowanzozivikanwawo seTeflon, Teflon, Teflon, Teflon zvichingodaro (zvese zveshanduro yeTeflon).

Teflon yakakamurwa kuita PTFE, FEP, PFA, ETFE akati wandei marudzi emhando: TEflon PTFE: PTFE (polytetrafluoron) isina-tsvimbo coating inogona kuramba ichishandiswa pa260 deG C, ine tembiricha yekushandisa yakanyanya ye290-300 DEG C, yakaderera kwazvo friction. coefficient, yakanaka kupfeka kuramba uye yakanakisa kugadzikana kwemakemikari. Teflon FEP: FEP (fluorinated ethylene propylene copolymer) isina-tsvimbo yekuputira inonyunguduka panguva yekubika kuti iite firimu risina porous, ine yakanakisa kugadzikana kwemakemikari, yakanakisa isina-tsvimbo zvivakwa, yakanyanya kupisa tembiricha i200 ℃. Teflon PFA: PFA (perfluoroalkyl) isina-stick coatings, seFEP, inonyunguduka panguva yekubika kuti iite porous firimu. Zvakanakira zvePFA zvakakwirira zvinoramba zvichishandisa tembiricha ye260 ℃, kuomarara kwakasimba, kunyanya yakakodzera kushandiswa kwekushisa kwakanyanya pasi pechimiro cheanti-stick uye makemikari kuramba mumunda wekushandisa. Teflon ETFE: ETFE icopolymer ye ethylene uye tetrafluoroethylene. Iyo resin ndiyo yakaomesesa fluoropolymer, ichigadzira yakasimba yakarukwa ine yakanakisa makemikari kuramba achishanda pa150 ° C.

Mushure mekuputirwa neTeflon, ine zvinotevera maitiro:

1, isiri-viscosity: zvinenge zvese zvinhu hazvina kusungwa ne teflon firimu. Mamembrane akatetepa kwazvo anoratidzawo akanakisa asina-adhesion zvivakwa.

2, kupisa kupisa: Teflon firimu ine yakanakisa kupisa kupisa uye yakaderera tembiricha kuramba. Nguva pfupi inogona kumira tembiricha kusvika 300 ℃, kazhinji pakati pe240 ℃ ~ 260 ℃ inogona kushandiswa nguva dzose, nekupisa kuri pachena hakuna kurongeka, inogona kushanda nechando tembiricha isina embrittlement, haina kunyungudika pakupisa kwakanyanya.

3, kutsvedza: Teflon firimu rine yakaderera coefficient of friction. Kana mutoro ukatsvedza, friction coefficient inoshanduka, asi kukosha kunongova pakati pe0.05 ne0.15.

4, kupikisa kwehunyoro: teflon firimu pamusoro haina kunamatira kumvura nemafuta, kutonga kwekugadzira hakusi nyore kunamatira kune mhinduro, senge shoma shoma yetsvina, nyore kupukuta kunogona kubviswa. Nguva pfupi yekuzorora, chengetedza nguva uye uvandudze kushanda zvakanaka.

5, kupfeka kuramba: pasi pemutoro wakakwira, ine yakanakisa kupfeka kuramba basa. Pasi pemumwe mutoro, ine zvakanakira zviviri zvekupfeka kuramba uye kusanamatira.

6. Corrosion resistance: Teflon inenge isingakwanisi kuparara kwezvinodhaka uye inogona kudzivirira zvikamu kubva kune chero rudzi rwekukukurwa kwemakemikari.
