Teflon ka baarakɛyɔrɔ min tɛ nɔrɔ ye, o baarakɛcogo ye mun ye?

Jiangsu Aokai New Materials, n’o ye Teflon fini ye min bɛ funteni caman bɔ, o bɛ dɔnniya ɲɛfɔ min bɛ a kɔfɛ.Teflon (tɔgɔ kemikali: Politetrafluoroethylene, PTFE) ka fɛn ɲumanba min tɛ nɔrɔ, o bɛ bɔ sariyakolo jɔnjɔn fila de la kosɛbɛ: a sanfɛla fanga dɔgɔyali  ani a molekiyɔmu jɔcogo kɛrɛnkɛrɛnnen.

1. Surface Energy min ka dɔgɔ kosɛbɛ

Nin ye physicochimique sariyakolo jɔnjɔn ye min bɛ baarakɛcogo la min tɛ nɔrɔ.Surface energy bɛ a jira cogo min na surface solide bɛ se ka jigin nɔgɔya la ni ji ye.

Teflon fanga ka dɔgɔn kosɛbɛ ( 18,5 mN/m ɲɔgɔn ), a ka dɔgɔ kosɛbɛ ka tɛmɛ nɔrɔlenw kan, tuluw walima ji kan (ji sanfɛla tansiyɔn bɛ se 72 mN/m ma).

Ka kɛɲɛ ni jibɔ miiriya ye , ji bɛ se ka jɛnsɛn yɔrɔ gɛlɛn dɔ kan dɔrɔn ni a sanfɛla girinya ka dɔgɔn ni fɛn gɛlɛn sanfɛla fanga ye.Ikomi fɛn fanba sanfɛla girinya ka bon ni Teflon ta ye, u tɛ se k’a sanfɛla jigin. O nɔ na, ​​u bɛ sɔgɔsɔgɔ ka kɛ jikuruw ye (i n’a fɔ ji min bɛ lotus bulu kan) ni ɲɔgɔnkanu yɔrɔ ka bon kosɛbɛ (a ka c’a la > 90°, hali ka surunya 120° la).

O kɔlɔlɔ : Nɔrɔlan ni Teflon ka ɲɔgɔn sɔrɔyɔrɔ yɛrɛ ka dɔgɔ kosɛbɛ, o la, masinw ka sirili ɲuman walima kemikɛli sirili ɲuman si tɛ se ka kɛ. O la, nɔgɔw bɛ sɔgɔsɔgɔ walima u bɛ se ka ko nɔgɔya la.

2. C–F jɛɲɔgɔnya barikamaw ani molekiyɔmuw jɔcogo min tɛ polari ye

Teflon ka molekiyɔmu jɔcogo ye karɔbɔni kɔkolo ye min lamininen don kosɛbɛ ni fluorine atomu ye.

·  Jɛɲɔgɔnya fanga caman : Karɔbɔni ni fluorine (C–F) jɛɲɔgɔnya ye jɛɲɔgɔnya barikama dɔ ye fɛnɲɛnamafagalanw na. O b’a to Teflon bɛ sabati kosɛbɛ kemikaliya siratigɛ la, wa a bɛ se ka kɛ ko a tɛ se ka baara kɛ ni fɛn bɛɛ ye (n’a ma fɔ nɛgɛ alkali wulilenw ni fluorin barikama damadɔw). A tɛ kemikɛli jɛɲɔgɔnya (kovalent walima hidrɔzɛni jɛɲɔgɔnya barikama) Kɛ ni fɛn nɔrɔlenw ye.

·  Polarite dɔgɔman : Hali ni fluorine ye elekitoronegatif ye kosɛbɛ, a labɛncogo simetriki cakɛda molekilɛri kan, o bɛ dipole moment bɛɛ ban. Teflon ye fanga ye min tɛ polari ye, a tɛ ji la, ani a tɛ tulu bɔ.Ji (polar) ni tulu (min tɛ polar ye nka a sanfɛla tension ka bon) tɛ se ka fanga belebelew dilan molekiyɔmuw ni ɲɔgɔn cɛ (van der Waals fanga barikamaw) ni Teflon ye.

3. Jɛɲɔgɔnya min bɛ coefficient de friction dɔgɔman ni non-stick performance cɛ

Hali n’a y’a sɔrɔ ko coefficient de friction (sɔgɔsɔgɔninjɛ) dɔgɔman bɛ sɛgɛsɛgɛli kɛ kosɛbɛ solide–solid sliding kan, a bɛ non-stick kɛcogo dafa.

Teflon bɛ ni coefficient dynamique friction coefficients dɔgɔmannin dɔ ye fɛn gɛlɛnw bɛɛ cɛma (a lamini 0.04).

Ni fɛn nɔrɔlenw y'a ɲini ka nɔrɔ, o sɔgɔsɔgɔninjɛ min ka dɔgɔ kosɛbɛ, o b'u bali ka 'minɛ' yɔrɔ la. Hali ni nɔrɔli barika ka dɔgɔ, kɛnɛma fanga walima girinya dɔɔni bɛ kɛ sababu ye ka fɛn in sɛgɛn ani ka bɔ nɔgɔya la.
