PTFE Fini min bɛ funteni caman sɔrɔ: Mun na a tɛ foli ka ɲɛ ani aw bɛ se ka min kɛ

Ni aw delila ka a yɔrɔ dɔ da PTFE-coated fibreglas fabric sharply, n’a sɔrɔla i ye crease line finman dɔ ye o yɔrɔnin bɛɛ. Aw bɛ a da tuguni o yɔrɔ kelen na, o la, fini bɛ se ka tigɛ.

Nin tɛ fiɲɛ ye – o ye fɛn dilannen ka kɛwale danma ye. PTFE fini min funteni ka bon, o ka fisa ni funteni, kemikɛlifɛnw ani nɔrɔli kunbɛnni ye, nka flex resistance (segin-segin muɲuli foli) ye a ka masinko barikama ye.

Aokai PTFE ye flex ɲɛnamaya kɔrɔbɔ ka tɛmɛn a janya ni a sɔgɔlen caman kan. Nin barokun b’a ɲɛfɔ mun na fini tɛ foli ka ɲɛ, k’a suma ni fɛn wɛrɛw ye, ani ka fɛɛrɛ ɲumanw di walasa ka danyɔrɔ in ɲɛnabɔ.

Mun na PTFE fini tɛ Flex Resistance ɲuman sɔrɔ?

O sababu ju ye fibreglasi substrat ye , a tɛ PTFE dacogo ye.

1. Fibreglasi – a barika ka bon nka a bɛ kari

Glass fibres ka sɔgɔli fanga ka bon kosɛbɛ nka u janya ka dɔgɔn kosɛbɛ kari waati (a ka c’a la 2-4%). Ni u kɔrɔtalen don siɲɛ caman, filanin kelen-kelen bɛɛ bɛ sɛgɛn ani ka kari. Ni fiɲɛ damadɔw karilen don, degun bɛ kɛ tɔw kan, o bɛ na ni u jɛnsɛnni teliya ye – fini bɛ tigɛ nɔgɔya la.

2. PTFE dacogo – tampon danma

PTFE layini bɛ fiɲɛw tulu, ka kɔnɔnafiliw dɔgɔya ani ka sɔgɔsɔgɔninjɛ ɲɛ dɔɔni. Nka, a tɛ se ka gilasi karilen bɔ yen. A bɛ fiɲɛ tiɲɛni bila kɔfɛ dɔrɔn ni danfara fitinin ye.

A bɛ se ka suma ni fɛn wɛrɛw ye cogo di?

Fɛn min bɛ ta: Fibreglasi min datugulen don ni PTFE ye, o sigilen bɛ cɛmancɛ la ka taa duguma dakun na finiw cɛma minnu funteni ka bon walasa ka flex resistance. A ka fisa ni galasi gansan ye nka a ka jugu kosɛbɛ ni PTFE filimu saniyalen ye.

Fɛn koloma minnu bɛ nɔ bila Flex Resistance la

1. Janya – o ye fɛn ye min ka gɛlɛn kosɛbɛ

Sariya min bɛ kɛ ka ɲɛ: Fini minnu ka fin, olu bɛ flexion ka ɲɛ. Ni aw bɛ baara kɛ minnu bɛ segin-ka-bɔnye kɛ, aw bɛ hakɛ finman dɔ fɔ min bɛ aw mago tɔw ɲɛ (fanga, funteni).

2. Weave jɔli

• Satin weave – floats janw bɛ a to jiriw ka sɛgɛn dɔɔni, ka bending stress tila. Flex ɲɛnamaya ka fisa ni plain weave ye.

• Weave plain – yɔrɔw sirilen sirilenw bɛ jiriw datugu; degun bɛ caya siraw cɛtigɛyɔrɔw la. Flex resistance jugumanba.

3. Baarakɛcogo funteni

Ni funteni ka bon (200-260°C), PTFE dacogo bɛ nɔgɔya, ani fibreglasi masin fanga bɛ dɔgɔya. O bɛ flex fatigue resistance juguya ka taa a fɛ. Ni aw ka furakɛli bɛ kɛ ni funteni caman ye ani ka to ka a biri, aw bɛ a jira ko a si hakɛ ka surun.

4. Kɔrɔtacogo

Radius ka bon = ɲɛnamaya jan. Kɛrɛnkɛrɛnnenya la (radius <1mm) bɛ foli salenw dilan ni fiɲɛ karilen ye yɔrɔnin kelen. Ni guide rollers don, aw bɛ baara kɛ ni diamètre pratique belebeleba ye. I n’a fɔ ɲɛjiralan gɛlɛn, wuluwulu janya min ka dɔgɔn, o ye finimugu janya siɲɛ 10-20 ye.

Kɔnɔna sɛgɛsɛgɛli kunnafoniw (Aokai PTFE) : Ni 0,13mm satin finimugu ye, ka kɔrɔta milimɛtɛrɛ 10 mandrel kan, o bɛ se ka 500-800 kɛ ka sɔrɔ ka kari ye. 5mm mandrel kan, cycles (cikanw) jigira ka se 100-150 ma. 2mm mandrel (crease sharp) kan, dɛsɛ kɛra cycle 20 kɔnɔ.

Ladilikanw minnu bɛ se ka baara kɛ ni u ye

Ni aw ka minɛnw bɛ a ɲini ka to ka ɲɔgɔn biri – i n’a fɔ:

• Welder drive belts minnu bɛ kɛ ni frequence haute ye

• Tension belts minnu bɛ siri jirisun misɛnninw na

• Demolding conveyor belts ni jiginni nɔgɔlenw

Sugandili saba bɛ aw bolo:

1. Sugandili 1 – Ka PTFE fini sugandili ɲɛ a dan na

• Aw bɛ a finmanw sugandi (0,08mm fo 0,13mm) ka tɛmɛ girinmanw kan

• Aw bɛ satin finiko ka fisa ni fini gansan ye

• Aw bɛ MIT flex sɛgɛsɛgɛli kunnafoniw ɲini aw ka feerekɛla fɛ (ASTM D2176 walima a ɲɔgɔnna) .

• Dilan ka ɲɛsin bending radii belebelebaw ma masin labɛncogo la

• Aw bɛ sɔn PTFE fini ma i n’a fɔ fɛn min bɛ se ka dun – aw ye fɛɛrɛ tigɛ walasa ka a falen waati ni waati (kalo damadɔ o kalo damadɔ ka kɛɲɛ ni cycle jate ye) .

2. Sugandili 2nan – Aw bɛ wuli ka taa PTFE filimu gɛlɛn na

PTFE filimu saniyalen (skived) bɛ ni flex resistance exceptionnelle ye. Nka, a tɛ ni fibreglasi barikalan ye, o la a ka sɔgɔli fanga ka dɔgɔn ani a bɛ tigɛ nɔgɔya la tension (jatigɛ) kɔrɔ. A bɛnnen don baarakɛcogo nɔgɔmanw ma, minnu bɛ kɛ ni tension dɔgɔman ye.

3. Sugandili 3nan – Aw bɛ aramid walima fini wɛrɛ kɛ ni fibre organique ye

Aramid (misali la, Nomex) walima PPS fini min datugulen don ni PTFE ye, o bɛ flex ɲɛnamaya di ka tɛmɛ PTFE fini kan min sinsinnen bɛ gilasi kan. Jagokɛcogo : funteni kunbɛncogo basigilen dɔgɔyali (a ka c’a la ≤200°C) ani dugukolo sanfɛla cogoya wɛrɛw. Ni aw bɛ a kɛ 200°C duguma ni a kurulen don kosɛbɛ, aw bɛ nin fɛɛrɛ wɛrɛw lajɛ.

Aokai PTFE bɛ fini aramidi dilan min datugulen don ni PTFE ye ni ɲinini kɛra. Aw ye anw sɔrɔ ka funteni ni flex data sɔrɔ.

Kuma surun – Danyɔrɔw dɔn, ka dilan ka kɛɲɛ ni o ye

PTFE fini min funteni ka bon, o bɛ jɔ kosɛbɛ ka ɲɛsin tension, funteni caman (260°C) ani kemikali binkanni ma. Nka a ka flex resistance jugu ye gɛlɛya lakika ye. A tɛ se ka muɲu ka segin-ka-bɔnye nɔgɔlenw muɲu i n’a fɔ lastikuw walima PTFE filimu saniyalen.

Aw bɛ baara kɛ n’a ye yɔrɔ minnu na a birili ka nɔgɔn walima a man teli ka kɛ yɔrɔ minnu na.
Yɔrɔ minnu na, a tɛ se ka bali ka kɔrɔta ni nɛgɛ ye walima ni a bɛ to ka kɛ, aw bɛ taa a finman, ka satin fini kɛ, ka dɔ fara a kuruli hakɛ kan, walima ka fɛn dɔ Changer.

Aokai PTFE bɛ flex test data di an ka finiw bɛɛ ma. An bɛ se k’aw dɛmɛ ka a janya ni a siricogo ɲuman sugandi ka kɛɲɛ ni aw ka application ka bending demands ye.
