Mun na PTFE fini min bɛ funteni caman na, o bɛ tasuma kɛlɛ tasuma dabɔlen na? A ka tasuma-fanga-minɛn min bɛ kɛ ni mikroskɔpi ye, o ye mun ye?

Jiangsu Aokai New Materials, n’o ye PTFE finiw dilanko ɲɛmɔgɔba ye, min funteni ka bon, o y’a ɲɛfɔ ko:

PTFE fini min funteni ka bon, o bɛ tasuma kɛlɛ kosɛbɛ tasuma dabɔlen na, kɛrɛnkɛrɛnnenya la a ka fɛn koloma — politetrafluoroethylene (PTFE) ka molekiyɔmuw jɔcogo n’a tiɲɛnicogo funteni fɛ. A ka tasuma-fanga-minɛnw tɛ Da tasuma-fanga-minɛnw faralenw kan i n’a fɔ fɛn gansanw, nka a bɛ Bɔ a ka kemikoro-yɔrɔ-ko la min bɛ a yɛrɛ la ani a ka tiɲɛni kɛcogo kɛrɛnkɛrɛnnen na.

O bɛ se ka faamuya ka bɔ dakun saba la:

1. Molecules barikama 'Armour': High Bond Energy ani Protective Layer

·  Karɔbɔni ni fluorine (C–F) jɛɲɔgɔnya barikama : PTFE mɔlikuluw bɛ kɛ ni karɔbɔni cakɛda kɔkolo ye min lamininen don kosɛbɛ ni fluorine atomu ye. C–F jɛɲɔgɔnya ye kemikɛli jɛɲɔgɔnya barikama dɔ ye min dɔnna, a jɛɲɔgɔnya fanga bɛ se 485 kJ/mol ɲɔgɔn ma. Fanga (funteni) camanba de ka kan walasa k’a kari, ka kɛ lafasali sira fɔlɔ ye.

·  Fluorine atomuw ka lakanani nɔ : Fluorine atomu belebelebaw, charge négative bɛ u la, olu bɛ pake ka caya, u bɛ kɛ i n’a fɔ kɛlɛkɛminɛn belebeleba min bɛ kɔnɔna karɔbɔli cakɛda datugu pewu. O barika bɛ kemikoro fanba (oksizɛni fana sen bɛ o la) bali ka don karɔbɔli cakɛda la ani ka oksidan walew bali kosɛbɛ minnu ka kan ka kɛ jeni kama.

2. Tiɲɛni min tɛ jeni: Depolimɛrize Sani a ka jeni

·  Cakɛda tigɛli sani oksidan ka kɛ : Ni funteni ka bon, PTFE kɔnɔ, karɔbɔni-karɔbɔni (C–C) jɛɲɔgɔnya minnu barika ka dɔgɔn, olu bɛ tiɲɛ sani C–F jɛɲɔgɔnya ka kɛ. Molecules cakɛdaw bɛ daminɛ ka toli sani oksizɛni ka se ka a sen don walew la.

·  Fɛn min bɛ sɔrɔ a la, o ye monomɛri ye : Ni a karilen don, PTFE bɛ kɛ depolimɛri la kosɛbɛ , ka tetarafluoroetilɛni (C2F4) monomɛriw bɔ cakɛda dakunw na. O fɛn bɛ kɛ lafiɲɛbɔ ye sanni a ka jeni kosɛbɛ min bɛ funteni ni gazi tasumama caman bɔ.

·  Gazi-fasa barika nɔ : C2F4 gazi min bɛ bɔ depolimɛri la, o ka bon ka tɛmɛ fiɲɛ kan, wa a bɛ sigi a sanfɛla kɛrɛfɛ, ka gazi kɛ waati dɔɔnin kɔnɔ min bɛ oksizɛni hakɛ dɔgɔya ani ka jeninida bali ka taa a fɛ.

3. Glass fibre substrate jɔyɔrɔ dɛmɛnan

PTFE fini min funteni ka bon, o ye fɛn ye min dilannen don ni PTFE dali ye gilasi fibre fini kan. Glass fibre yɛrɛ ye fɛn ye min tɛ tasuma ye, min tɛ fɛnɲɛnama ye. I n’a fɔ jɔli kolotuguda, a b’a to hali ni sanfɛla PTFE layini bɛ ban ka ban funteni jugumanba la, a fɛn tɛ wuli walima ka jigin i n’a fɔ plastiki saniyalen, o bɛ jɔli dafalen mara ani ka tasuma bali ka jɛnsɛn.

A ka kan ka sinsin a kan ko PTFE tɛ tasuma bɔ , a tɛ tasuma bɔ pewu.Ni a sumana ka tɛmɛ a wulicogo kan (327°C) ani ka to ka a to, a bɛ toli ka sisi baga bɔ. A ka c’a la, a bɛ funteni kuntaalajan muɲu fo ka se 260°C ma, wa a bɛ to a cogo la waati kunkurunnin kɔnɔ 300–360°C la.

Tiɲɛni tasuma dafalen na : Ni a bilara tasuma dabɔlen na k’a ɲɛsin a ma (a ka toli funteni sanfɛ kosɛbɛ), PTFE layini bɛ toli, nka o kɛcogo tɛ funteni walima jenifɛn bɛrɛ lase walasa ka jenini sabati. Ni aw farala galasi fiyɛri dɛmɛnan kan, tasuma tɛ se ka jɛnsɛn ka taa a fɛ.

Kuma surun na, PTFE fini min bɛ funteni caman na, o tɛ tasuma kɛlɛ bawo a kɔnɔfɛn PTFE dilannen don molekiyɔmu siratigɛ la walasa ka jeni kunbɛn .Kimikɛ sirili fanga caman bɛ min na, tiɲɛni sira kɛrɛnkɛrɛnnenw, ani gilasi fiyɛri kolotuguda min tɛ tasuma ye, olu faralen ɲɔgɔn kan, u bɛ kɛ tasuma-fagalan barikama ye.

Kunnafoni minnu bɛ sanfɛ, olu dira Jiangsu Aokai New Materials Technology Co., Ltd fɛ.

Walasa ka paramɛtiriw ɲɛfɔ ka ɲɛ, baarakɛcogo misaliw ani an ka fɛn dilannenw bɛɛ lajɛlen ɲɛnabɔcogo labɛnna — i n’a fɔ PTFE fini min bɛ funteni caman bɔ, PTFE kasɛti min bɛ funteni caman bɔ, PTFE cɛsirilan min bɛ funteni caman bɔ, cɛsirilan min tɛ sɔgɔsɔgɔ ka ɲɛsin sirili masinw ma, PTFE fini min bɛ kɛ fan kelen fɛ, cɛsirilan min bɛ se ka funteni caman kɛlɛ, galasi fibre fini min bɛ se ka funteni caman kɛlɛ ani fɛn wɛrɛw minnu bɛ tali kɛ o la products — aw bɛ se ka anw sɔrɔ:
