Taabolo jɔnjɔn dafalen bɛ Kɛ ni fɛɛrɛ jɔnjɔn wolonwula ye i n’a fɔ ninnu:
1. Fibreglasi fini furakɛli ka kɔn (Dewaxing / Desizing) .
Nin ye fɛɛrɛ ye min ka gɛlɛn kosɛbɛ sani furakɛli ka kɛ. Fini hakɛ jateminɛfɛn dɔ (kɛrɛnkɛrɛnnenya la parafin cire, amidon bɔlenw) bɛ datugu fibreglasi filamanw kan finiko waati; ni bɔli dafalen tɛ, o bɛna PTFE ni gilasi fiyɛw cɛ jɛɲɔgɔnya tiɲɛ kosɛbɛ.
· Furakɛli fɛɛrɛ kunba : Fini bɛ tɛmɛ tuma bɛɛ foro kɔnɔ min funteni ka bon walasa ka funteni bɔ a la 350~400°C la, ka oksidan dafalen kɛ ani ka fɛnɲɛnamafagalanw bɛɛ tiɲɛ.
· A kɛcogo tuguni : Fini min ma kɛ ni siro ye, o bɛ nɛnɛ, tuma dɔw la, a bɛ ko ni ji sanuman ye walima ni kemikɛlifɛnw ye walasa ka bɔgɔ tolen bɔ a la, o kɔfɛ, a bɛ ja walasa ka fini finman jɛlen sanuman sɔrɔ min labɛnnen don ka don a kɔnɔ.
2. PTFE Emulsion (Emulsion) furakɛlicogo
· Fɛnɲɛnamafagalan : PTFE jɛnsɛnni min bɛ kɛ ni fɛnmugu ye min bɛ se ka kɛ 60% ɲɔgɔn ye.
· Aw bɛ ɲagami kɛcogo : Aw bɛ stock dispersion (ji min tɛ ionize) kɛ, aw bɛ o kɛ ka a kɛ a hakɛ laɲininen ye (40%–55%) ka da resin doni wajibiyalen kan ani impregnation viscosity (ji min bɛ kɛ ka a sɔgɔ. Surfactant bɛnnen bɛ fara a kan walasa ka jisigicogo ɲɛ fibreglasi kan; fɛnɲɛnamafagalan bɛ se ka don a la walasa ka a sɔgɔli ladilan ni a mago bɛ a la.
3. Kɔnɔtiɲɛ
Laɲini koloma ye PTFE emulsiyɔn doncogo dafalen ye fibre bundles ni fini tigɛlen cɛmancɛw kɔnɔ.
1. Dip-Squeeze Method (A bɛ kɛ ka caya): Fini bɛ bilasira ni jisuma-minɛnw ye walasa ka a su pewu emulsiyɔn tanki kɔnɔ, o kɔ a bɛ tɛmɛ sɔgɔsɔgɔninjɛ-minɛn fila fɛ. Coating girinya bɛ kɔlɔsi ni roller nip tansiyɔn ladilanni ye walasa ka emulsion tɛmɛnen bɔ ani ka resin tila ɲɔgɔn na.
2. Dɔgɔtɔrɔ ka nɛgɛdacogo: Emulsiɔn bɛ jɛnsɛn fini sanfɛ nɛgɛdaga fɛ, min bɛnnen don fɛnw jɛnsɛnni ma minnu bɛ kɛ ni sɔgɔsɔgɔninjɛ ye.
4. Jali
Fini min falen don, o bɛ don jalen foro kɔnɔ min funteni ka dɔgɔn, a bɛ baara kɛ 100~150°C la.
· Kuntilenna : Aw bɛ ji ni surɔfɛnw yɔrɔ dɔw labɔ dɔɔni dɔɔni, ka PTFE fɛnɲɛnamaw ka filimu jalen dɔ kɛ hali min tɛ nɔrɔ fiyɛriw kan.
· Funteni kɔlɔsili kɔlɔsili : Funteni caya kojugu bɛna kɛ teliya la ka kɛ yɔrɔ ye min ka bon, ka kɔnɔna ji minɛ min bɛ kɛ lafiɲɛbɔ ye ka kɛ pinɛw ni kurukuruw ye.
5. Sintering (Kɛnɛya min bɛ kɛ ni funteni ye) .
Fini jalen bɛ don o yɔrɔnin bɛɛ sintering foro kɔnɔ min funteni ka bon walasa ka a furakɛ ni funteni ye 360~390°C (fo ka se 400°C ma kalasi dɔw la).
· Fɛɛrɛ : PTFE ye polimɛri ye min bɛ kɛ ni funteni ye. Ni funteni bɛ a wuliyɔrɔ sanfɛ kosɛbɛ (327°C), PTFE fɛnɲɛnamafagalanw bɛ wuli, ka woyo ani ka kɛ kelen ye ka kɛ filimu ye min bɛ to senna, o bɛ se ka kɛ sababu ye ka masinw ka ɲɔgɔn siri ani ka nɔrɔ fibreglasi yɔrɔw la.
· Stage tilali : Sintering yɔrɔ tilalen don ka kɛ funteni-yɔrɔ ye, funteni basigilen sintering ani cooling segments walasa ka garanti (dafalen) kɛ fɛnɲɛnamafagalanw ka ɲɔgɔn sɔrɔli dafalen na k’a sɔrɔ funteni ma tiɲɛ.
6. Sikili caman ka Impregnation & Sintering
Impregnation-sintering cycle kelen bɛ dɔrɔn ka finimugu finmanba dɔ lawuli min ka teli ka kɛ pinhole defects ye. Walasa ka se laɲinilen dacogo janya ni resin hakɛ ma (misali la, 45%–65% resin doni ka ɲɛsin laminatiw ma minnu bɛ kɛ ni nɛgɛ ye minnu bɛ kɛ ni frequence caman ye), impregnation → drying → sintering sinsinni dafalen bɛ segin siɲɛ 2 fo siɲɛ 4 walima ka tɛmɛ o kan. Siginiden kelen-kelen bɛɛ bɛ fiyɛri yɔrɔw fa ka t’a fɛ ani ka dɔ fara finimugu janya kan, ka laban ka kɛ fɛn ye min bɛ kɛ ni finimugu ye min tɛ pinɛw ye.
7. Furakɛli kɔfɛ & Winding
1. Yɔrɔ caman caman cili : Sintiri laban tɛmɛnen kɔfɛ, korona furakɛli walima sodium-naphthalene etching kemikali bɛ se ka kɛ walasa ka surface nɔrɔli ɲɛ ka sɔrɔ a ma tiɲɛni kɛ substrat la, o bɛ kɛ sababu ye ka nɛgɛdaga kɔfɛ walima ka fini filanan nɔgɔya.
2. Edge trimming & winding: Fini dakunw bɛ tigɛ ka ɲɛ, o kɔfɛ fini dafalen bɛ jogin ka ɲɛ ni taasibila masin ye.
3. Jogoɲumanya sɛgɛsɛgɛli : Fɛn dilannenw sɛgɛsɛgɛli bɛɛ lajɛlen i n’a fɔ basigi girinya, u bonya, u sɔgɔli fanga, u ɲɛkisɛ fanga, u dielektriki basigilen ani u ɲɛnayeli nafama.
Taabolo kɔrɔlenw kɔlɔsili yɔrɔw
Paramɛtiri kɔrɔ minnu bɛ fɛn dilannenw jogo ɲɛnabɔ, olu ye : u bonya/bɔli dafalen, emulsiyɔn jilama dafalen, jalen dɔɔni dɔɔni funteni dɔgɔyalen na, sintering funteni sigicogo tigitigi, ani finimugu density basigilen, impregnation cycle caman kɔfɛ.
N’aw b’a fɛ ka fɛn ɲɛfɔlenw sɔrɔ, baarakɛcogo misaliw ani furaw labɛncogo la an ka fɛn dilannenw bɛɛ lajɛlen kama 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 funteni digi, PTFE fini min bɛ kɛ fan kelen fɛ, cɛsirilan min bɛ se ka funteni caman kɛlɛ ani fini min bɛ se ka funteni kɛlɛ, aw bɛ se ka anw sɔrɔ kunnafoniw fɛ minnu bɛ duguma:
An bɛ tugu baarakɛlaw ka baarakɛcogo hakilila la tuma bɛɛ, min ɲɛsinnen bɛ danbe ma, ka izini ɲɛnabɔcogo kelenw di ni an dusukun bɛɛ ye ani ka kiliyanw dɛmɛ ni hakilijagabɔ ye jɛɲɔgɔnw bɛɛ ye!
