Yɛlɛma donna PTFE kristali jɔcogo la PTFE fini funtenimanba sɔgɔli waati

Jiangsu Aokai New Materials, n’o ye PTFE fini funteniman dilannikɛla ŋana ye, o bɛ kunnafoni caman di PTFE kristalɛ jɔcogo jiginni kan PTFE fini funteni caman sɛnɛcogo bɛɛ kɔnɔ.

I. Kristali jɔcogo fɔlɔ tiɲɛni

1. PTFE kristalɛ cogoya ka sɔrɔ ka sinter kɛ

Sani sinter ka kɛ, PTFE bɛ sɔrɔ i n’a fɔ emulsiyɔn fɛnɲɛnamafagalanw jɛnsɛnnenw minnu sirilen don fibreglasi fini na. Lamɛla minnu bɛ kɛ ni cakɛda dabɔlenw ye minnu bɛ kristalɛ kosɛbɛ, olu bɛ ni fɛn misɛnninw ye minnu labɛnna ka ɲɛ.

2. Jagokɛcogo caman caman cili funteni waati la sintering kama

Ni funteni wulila ka tɛmɛ a wuliyɔrɔ kan (~327°C), kristalɛ bɛɛ bɛ wuli pewu. Molecules cakɛda minnu dabɔra, olu bɛ dabɔ ani ka bɔ ɲɔgɔn na, ka wuli ka kɛ fɛn ye min tɛ fɛn ye. Fɛnɲɛnɛma dan fɔlɔw bɛ tunun ni fɛnɲɛnɛmaw bɛ ɲɔgɔn sɔrɔ ka kɛ fasa wulilen ye min bɛ to senna, ka kristali fɔlɔ granulaire jɔcogo tiɲɛ pewu.

II. Recrystallisation (Kristallisation) Nɛnɛ waati

1. Spherulitic structures (sɛrɛkiliw) jɔli

Ni nɛnɛna ka bɔ a wulilen cogo la, PTFE bɛ teliya ka kirisitali kɛ kokura ka kɛ sɛrɛkiliw ye minnu bɛ kɛ ni lamɛli cakɛda folilenw ye minnu ɲɛsinnen bɛ radiyali ma, minnu bɛ taa kɛnɛma ka bɔ cɛmancɛ nukilisi yɔrɔw la. O spherulite minnu bɛ don ɲɔgɔn na, olu bɛ kristalɛ matiriyali dɔ jɔ min bɛ taa ɲɛ, ka fɛnɲɛnamafagalan pakew jɔcogo fɔlɔ bila a nɔ na.

2. Yɛlɛma donna kristalɛ laban na

PTFE bɛ ni cakɛda gɛlɛnw ye, minnu bɛ kɛ tuma bɛɛ, minnu bɛ kristali teliyaba di hali ni nɛnɛ teliyalen don kosɛbɛ. A ka c’a la, kristalini laban bɛ bɔ 50% na ka se 70% ma, o bɛ dɔgɔya dɔɔnin ka tɛmɛ emulsiyɔn fɔlɔw ta kan.

III. Kristali paramɛtiriw ni kristali cogoyaw jiginni

1. Ka kristalɛ fasa sabatilen mara

Nɛnɛ kɔfɛ fo ka se so funteni ma, PTFE bɛ kristalɛ sitɛmu sabatilen mara (so funteni fasa wɔɔrɔ), min ni a ka kristalɛ cogoya bɛ kelen ye ka kɔn sintering ɲɛ. Jiginni bɛɛ bɛ Kɛ kristalɛ hakɛ la, dafalenya la ani a cogoya la sanni ka Kɛ kristalɛ fasa laban ye.

2. Nɛnɛ hakɛ nɔ min bɛ kristalɛ dafalen na

· Ni nɛnɛ kɛra dɔɔni dɔɔni, o bɛ kristali caman sɔrɔ, ka sɛrɛkiliw ka bon ani ka lamɛla belebelebaw sɔrɔ, minnu ɲɛfɔlen don kosɛbɛ, o bɛ na ni fɛnw ye minnu ka gɛlɛn ani minnu ka bon.

· Ni a fagali teliya la, o bɛ na ni kristali dɔgɔyali ye kosɛbɛ, ka spherulite finmanw, dafalenw dɔgɔya, ani ka fɛn dilannenw ka fɛn dilannenw ka sɛgɛsɛgɛli ni u ka semi-transparency ɲɛ. Nɛnɛ dɔɔni ye sariya ye PTFE fini funteniman na walasa ka masin fanga wajibiyalenw dafa.

IV. Crystallisation interfaciale nɔ min bɛ fibreglasi kan ani a nafa bɛɛ lajɛlen

1. Transcrystallisation (Kɔnɔnafiliko) ko ye

Ni PTFE wulilen nɛnɛna fibreglasi yɔrɔw kan, nucleation sites dense minnu bɛ fibre surface kan, olu bɛ transcrystallisation bila: kristalɛ kolomayɔrɔ dɔ bɛ bonya ka kɛɲɛ ni fibre axis ye, o ni spherulite cogoya tɛ kelen ye kosɛbɛ bulk coating kɔnɔ.

2. Gradient structure ka bɔ fibre interface la ka taa coating bulk la

Fibreglasi ka fanga kɔrɔ, PTFE kristalɛ jɔcogo bɛ jiginni kɛ jiginni na: transcristalline layɛrɛ min bɛ fiɲɛw kɛrɛfɛ, o bɛ wuli dɔɔnin dɔɔnin ka kɛ spherulitic structures ye kɔnɔna finimugu matirili kɔnɔ.

3. Jagokɛyɔrɔ jiginni nɔ latigɛlen don PTFE fini baarakɛcogo la

Sintering bɛ PTFE kristalɛ granular folded-chain caman sɛmɛntiya : u bɛ wuli ani ka jɔcogo tiɲɛ, o kɔfɛ u bɛ kirisita kokura ka kɛ spherulites continues, dense (ni interfacial transcrystalline layers ye). O bɛ mugu pakew lajɔlenw sɛmɛntiya ka kɛ filimu ye min tɛ tiɲɛ, o min ye fɛnba ye min ka kan ka kɛ walasa finimugu ka baara kɛcogo bɛɛ lajɛlen di i n’a fɔ funteni kunbɛnni, sɔgɔsɔgɔninjɛ dɔgɔyali, a tɛ nɔrɔ ani kemikɛli sɔgɔli kunbɛnni.

N’aw b’a fɛ ka fɛn ɲɛfɔlenw sɔrɔ, baarakɛcogo misaliw ani fura minnu bɛ kɛ ka kɛɲɛ ni mɔgɔw sago ye an ka fɛn dilannenw bɛɛ lajɛlen na i n’a fɔ PTFE fini min bɛ funteni caman bɔ, PTFE kasɛti nɔrɔlen min bɛ funteni caman na, PTFE cɛsirilan min bɛ funteni caman bɔ, cɛsirilan min bɛ kɛ ni funteni ye, PTFE fini min bɛ kɛ fan kelen fɛ, cɛsirilan min bɛ se ka funteni caman kɛlɛ ani fibreglasi min bɛ se ka funteni kɛlɛ fini, aw bɛ se ka anw sɔrɔ kunnafoniw fɛ minnu bɛ duguma:

· Baarakɛyɔrɔ telefɔni nimɔrɔ: Mr. Liu +86 13705266308

An bɛ baarakɛcogo ɲuman ni danbe sabati i n’a fɔ an ka jago hakilila jɔnjɔn, ka izini ɲɛnabɔcogo kelenw di ni an dusukun bɛɛ ye ani ka kiliyanw dɛmɛni kɛ ni hakili ye jɛɲɔgɔnw bɛɛ ye!
