PTFE Tape Adhesion vs Temperature: A bɛ se ka kɛ cogo min na

Jiangsu Aokai New Materials, n’o ye PTFE kasɛti ye min bɛ se ka funteni caman sɔrɔ, o bɛ baarakɛlaw ka hakilinaw di aw ma.

PTFE (Teflon) kaseti funteni caman bɛ se ka kɛ caman na tuma bɛɛ funteni hakɛ la min bɛ se -196°C fo 260°C ma . Baara fanba la, kaseti ka funteni kunbɛncogo dan bɛ dan kɛ ni nɔrɔlan ye  sanni ka dan PTFE substrat ma. A baarakɛcogo bɛ tugu sariya jɛlenw kɔ minnu ɲɛsinnen bɛ funteni ma:

Nɛgɛdaga baarakɛcogo bɛ dɔgɔya ni funteni bɛ wuli  Ni funteni bɛ ka bonya, nɔrɔli bɛ nɔgɔya dɔɔni dɔɔni, ka wuli ani ka tiɲɛ yɛrɛ, o bɛ na ni sirili fanga dɔgɔyali ye. Macroskopi la, o bɛ ye i n’a fɔ minɛni nɔrɔli jigincogo.

Baarakɛcogo dantigɛli min bɛ latigɛ ni nɛgɛ suguya ye  Nɛgɛ suguya wɛrɛw ka dɛsɛ funteni tɛ kelen ye kosɛbɛ:

 

Walasa ka funteni caman minɛ waati ɲɛ , optimisation bɛ kɛ kɛrɛnkɛrɛnnenya la ka bɔ fan saba la: nɔrɔli dilanni, substrat baarakɛcogo, ani ɲɔgɔndan sigicogo.

1. Adhesive Layer: Aw bɛ Weak Link (Jɛkulu barikama) sɛmɛntiya

·  Aw bɛ nɔrɔlan sugandi min bɛ se ka funteni caman kɛlɛ : Aw bɛ silikɔni tansiyɔn nɔrɔlan bila jɔyɔrɔ fɔlɔ la baarakɛcogo la min bɛ mɛn funteni caman na.

·  Fluorocarbone caman cili : Aw bɛ silikoni nɔrɔlan caman sɛmɛntiya ni fluorocarbone fɛnɲɛnamafagalanw ye walasa ka gilasi jiginni funteni (Tg) kɔrɔta ka se 230°C ma. Lɛrɛ 48 kɛlen kɔ ka to ka a kɛ 260°C la, a nɔrɔli hakɛ bɛ tɛmɛ 85% kan hali bi.

·  Ka ɲɔgɔndan rezo don : Ka nano-scale crosslinking networks dilan walasa ka nɔrɔlan ka jɛɲɔgɔnya fanga ni a ka sɔgɔsɔgɔli fanga bonya kosɛbɛ funteni caman na.

·  Aw bɛ funteni sabatilifɛnw fara a kan : Aw bɛ fenɔli balilen ni funteni sabatilifɛn wɛrɛw don furakisɛ kɔnɔ walasa ka oksidan tiɲɛni bali ka ɲɛ funteni caman na.

2. Substrate Layer: Aw bɛ funteni hakɛ bɛɛ lajɛlen kunbɛncogo kɔrɔta

·  Nano-filler modification : Aw bɛ nano silica, boron nitride nanotubes ani nanoparticules wɛrɛw fara PTFE substrat kɔnɔ walasa ka farikoloɲɛnajɛ yɔrɔw dilan. Funteni jiginni funteni bɛ se ka bonya ni 20–30°C ye, ka sɔrɔ ka 90% ni kɔ mara fɔlɔ nɔrɔli la 260°C la.

·  Molecules crosslinking treatment : PTFE molekiyɔmu cakɛdaw tigɛli walasa ka baara kɛcogo basigilen kɔrɔta fo ka se 300°C ma.

·  Fiyɛri barika bonya : Aw bɛ gilasi fibre walima fibre carbone 25% fara a kan walasa ka creep resistance bonya ni 300% ye, o bɛ kɛ sababu ye ka baara kɛ ni a ye ka taa a fɛ fo ka se 280°C ma.

3. Interface & Structural Design: Ka jɛɲɔgɔnya sabatili sabati

·  Substrat surface treatment : Aw bɛ plasma furakɛli walima kemikɛli kɛ PTFE surface kan walasa ka dɔ fara a gɛlɛya kan ani ka surface baara caya, ka interfacial adhesion barika bonya ani ka aw yɛrɛ tanga delamination ma funteni caman na.

·  Aw bɛ cɛmancɛ barikalan fara a kan : Aw bɛ poliimidi (PI) danfaralan dɔ don PTFE substrat ni nɔrɔlen cɛ walasa ka nɔrɔlenw doncogo ni u jiginni bali funteni caman na, o bɛ sigida bɛɛ sabatili ɲɛ.

·  Ka fɛnɲɛnamafagalanw sigicogo ɲɛ : Aw bɛ fɛn caman ta minnu bɛ kɛ ɲɔgɔn fɛ : PTFE coating + reinforcing substrate + high-temperature stable layer , walasa ka funteni kunbɛnni ni nɔrɔli baara kɛcogo bɛn ɲɔgɔn ma cogo bɛɛ la.

·  Reserve thermal expansion clearance : PTFE ka coefficient de expansion lineaire bɛ se ka kɛ nɛgɛ ta siɲɛ 10 ɲɔgɔn ye.

Aw bɛ yɔrɔ dɔ mara min ye milimɛtɛrɛ 0,15–0,3 ye  jɔli la walasa ka funteni degun bɔ ka ɲɛ.
