I-Teflon yaziwa kakhulu ngokuthi i-polytetrafluoroethylene (isifinyezo sesiNgisi se-teflon noma i- [PTFE, F4]), eyaziwa ngokuthi/ngokuvamile eyaziwa ngokuthi “inkosi yepulasitiki”, futhi yaziwa nangokuthi “i-Teflon”, “Teflon”, “Teflon”, “Teflon”, "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon", "Teflon". Kuyinhlanganisela ye-polymer eyenziwe nge-tetrafluoroethylene nge-polymerization, futhi ukwakheka kwayo kulula njengokuthi--[-cf2-cf2 -]n-.

I-Polytetrafluoroethylene, evame ukubizwa ngokuthi i-non-stick coating noma into elula ukuyihlanza. Le nto inezici zokuphikiswa kwe-asidi ne-alkali, ukumelana nezinyibilikisi ezihlukahlukene eziphilayo, futhi cishe ezingancibiliki kuzo zonke izincibilikisi. Ngesikhathi esifanayo, i-polytetrafluoroethylene inezici zokumelana nokushisa okuphezulu, i-coefficient yayo yokungqubuzana iphansi kakhulu, ngakho-ke ingasetshenziselwa ukugcoba, kodwa futhi ibe ukugqoka okuhle ukuze kube lula ukuhlanza ungqimba lwangaphakathi lwamapayipi amanzi.

I-Teflon Plating incike kakhulu ekutheni hlobo luni lwenqubo ofuna ukunquma ukuthi ufafaza kanjani. Okubaluleke kakhulu ukuthi i-Teflon coating idinga ukubhakwa emazingeni okushisa aphezulu ngaphambi kokuba isetshenziswe.

Izimpawu ze-Teflon:

Okunganamatheli: Cishe zonke izinto azihlangani ne-teflon enamathela.

Ukumelana nokushisa okuphansi: ukuqina okuhle kwemishini; Ngisho noma izinga lokushisa lehla liye ku-196 ° C, ukuphakama okungama-5% kungagcinwa. Kusathambile ku -100 degrees.

Ukumelana nokushisa okuphezulu: i-polytetrafluoroethylene coating inokushisa okuhle kakhulu nokumelana nokushisa okuphansi. Ingakwazi ukumelana nezinga lokushisa eliphezulu ukuya ku-300 ° C isikhathi esifushane, ngokuvamile ingasetshenziswa ngokuqhubekayo phakathi kuka-240 ° C no-260 ° C, futhi inokuqina okushisayo okuphawulekayo, ingasebenza emazingeni okushisa aqandayo ngaphandle kokushisa, futhi ayincibiliki emazingeni okushisa aphezulu. .

I-lubrication ephezulu: I-coefficient ephansi yokungqubuzana kwezinto eziqinile. Ine-coefficient ephansi yokungqubuzana (0.04) phakathi kwamapulasitiki. Ubushelelezi kuneqhwa.

Ukumelana nomswakama: ingaphezulu le-PTFE yokugqoka ayingcolisiwe ngamanzi namafutha, futhi akulula ukunamathela kusixazululo ngesikhathi sokusebenza kokukhiqiza. Uma kukhona ukungcola okuncane, kungasuswa ngokusula nje. Isikhathi esifushane songa isikhathi futhi sithuthukisa ukusebenza kahle komsebenzi.

Ukumelana nokugqoka: Inokumelana okuhle kakhulu kokugqoka ngaphansi komthwalo ophezulu. Ngaphansi komthwalo othile, unezinzuzo ezimbili zokumelana nokugqoka nokungabambeleli.

Ukumelana nokugqwala: i-polytetrafluoroethylene icishe ikhululeke ekuhlaselweni yizidakamizwa, futhi ingamelana nawo wonke ama-acids aqinile (kuhlanganise ne-aqua aqua), ama-oxidants aqinile, ama-ejenti anciphisayo nezinyibilikisi ezihlukahlukene eziphilayo ngaphezu kwezinsimbi ezincibilikisiwe ze-alkali, imidiya ene-fluorinated ne-sodium hydroxide engaphezu kuka-300 ° C, kanye ingavikela izingxenye kunoma yiluphi uhlobo lokugqwala kwamakhemikhali.

Ukumelana nokuguga: ukumelana nemisebe kanye nokungena okuncane: ukuchayeka isikhathi eside emkhathini, indawo engaphezulu nokusebenza kuhlala kungashintshile.

Okungashi: Inkomba yomkhawulo we-oxygen ingaphansi kwama-90.

Ukuphikiswa kwe-Acid ne-alkali: okungancibiliki kuma-asidi aqinile, izisekelo eziqinile nezincibilikisi eziphilayo (kuhlanganise ne-magic acid, okungukuthi, i-fluoroantimonic acid).

Ukumelana ne-oxidation: ukumelana nokugqwala ngama-oxidants aqinile.

I-Insulation: Ukusebenza kahle kukagesi, kuyinto ekahle yokufakwa kwe-C-class, ungqimba lwephephandaba eliwugqinsi lungavimba ingcindezi ephezulu engu-1500V. I-insulation yayo kagesi ayithinteki ukushisa. I-dielectric constant kanye nokulahlekelwa kwe-dielectric kuphansi ebangeni elibanzi lefrikhwensi, futhi i-voltage yokuphuka, ukumelana nevolumu nokumelana kwe-arc kuphezulu.

I-Acid-base: i-neutral.
