Wetin na di Wok Prinsipul fɔ Teflon in Nɔn-Stik Surface?

Jiangsu Aokai Nyu Matirial, we na wan sɔs manifakta fɔ Teflon ay-tɛmpracha klos, ɛksplen di sayɛns biɛn am.Di fayn fayn nɔ-stik prɔpati fɔ Teflon (kɛmikal nem: Polytetrafluoroethylene, PTFE) men wan kɔmɔt frɔm tu kɔr prinsipul dɛn: lɔw sɔfayz ɛnaji  ɛn in yon mɔlikul strɔkchɔ.

1. Ekstrim Lɔw Sɔfays Ɛnaji

dis na di fכndamεntכl fyzikokεmikכl prinsipul fכ nכn-stik pεrformεns.Sכfayz εnεji de ditarεmin aw izi wan sכlid sεf kin wet bay likwid.

Teflon gɛt wan rili lɔw sɔfayz ɛnaji (lɛk 18.5 mN/m ), we rili smɔl pas kɔmɔn adeziv, ɔyl, ɔ wata (sɔfa tɛnsiɔn fɔ wata na lɛk 72 mN/m).

Akɔdin to di wetin tiori , wan likwid kin jɔs spre pan sɔlid sɔfays if in sɔfayz tɛnsiɔn smɔl pas di sɔlid in sɔfayz ɛnaji.Bikɔs di sɔfayz tɛnsiɔn fɔ bɔku tin dɛn ay pas di wan fɔ Teflɔn, dɛn nɔ kin wet in sɔfays. bifo dat, dεn kin kכntrakt to dכp dεm (lεk wata pan lכtus lif) wit wan vεri hכy kכntakt angle (usually > 90°, ivin klos to 120°).

Rizult : Di aktual kɔntakt eria bitwin di adeziv sɔbstans ɛn Tɛflɔn rili smɔl, so nɔ ifektiv mɛkanikal ankɔring ɔ kemikal bondin nɔ kin apin. So di tin dɛn we de dɔti kin slayv ɔ dɛn kin was am izi wan.

2. Strɔng C–F Bɔnd ɛn Nɔn-Polar Mɔlikul Strukchɔ

Teflon na strכng wan nכn-polar, haydrofobik, εn oleophobic.Wata (polar) εn כyl (nכn-polar bכt hεy sכfayz tεnshכn) nכ kin fכm signifyant intamכlikul fכs (wik van der Waals fכs) wit Teflon.

3. Sinaji Bitwin Lɔw Frikshɔn Kɔfishin ɛn Nɔn-Stik Pɔfɔmɛnshɔn

pan ɔl we wan lɔw frikshɔn kɔfishin de men wan diskrayb sɔlid–sɔlid slaydin, i de kɔmplimɛnt nɔ-stik bihayvya.

Teflon gɛt wan pan di lɔs dinamik frikshɔn kɔfishin bitwin ɔl di sɔlid matirial dɛn (arawnd 0.04).

we stika tin dεm de tray fכ adhere, di frikshכn we rili lכw de mek dεn nכ 'grip' di sכfa. Ivin wit wik adheshon, smɔl eksternal fos ɔ graviti de mek di matirial slayv ɛn detach izi.
