Dɛn Nti na PTFE Ntama a Ɛyɛ Ɔhyew a Ɛkorɔn no Ntumi Ntumi Nhyew wɔ Ogya a Wɔabue Mu? Dɛn Ne Ne Afiri a Ɛma Ogya Ntumi Nhyew a Ɛyɛ Microscopic?

Jiangsu Aokai New Materials, adwumakuw bi a ɛyɛ PTFE ntama a ɛyɛ hyew kɛse no kyerɛkyerɛ mu sɛ:

PTFE ntama a ɛyɛ hyew kɛse no tumi gyina ogyaframa ano kɛse wɔ ogya a wɔabue mu, titiriw esiane molecule nhyehyɛe ne ɔhyew a ɛporɔw afiri a ɛwɔ ne ade titiriw — polytetrafluoroethylene (PTFE) mu nti. Ne ogyaframa a ɛmma ogya ntumi nhyew no nnyina ogyaframa a wɔde aka ho te sɛ nneɛma a ɛyɛ mpapahwekwa so, na mmom efi ne nnuru a ɛnyɛ adwuma a efi awosu mu ne ne porɔw suban soronko no mu.

Yebetumi ate eyi ase afi nsɛm abiɛsa mu:

1. Molecular a ɛyɛ den 'Armour': High Bond Ahoɔden ne Ahobammɔ Layer

·  Carbon-fluorine (C–F) nkitahodi a emu yɛ den : PTFE molecule ahorow no yɛ carbon nkɔnsɔnkɔnsɔn akyi dompe a fluorine atɔm atwa ho ahyia denneennen. C–F nkitahodi no yɛ nnuru nkitahodi a emu yɛ den sen biara a wonim no mu biako, a nkitahodi ahoɔden bɛyɛ 485 kJ/mol. Ahoɔden (ɔhyew) a ɛkorɔn yiye ho hia na ama wɔabubu, na ayɛ ɔkwan a edi kan a wɔfa so bɔ wɔn ho ban.

·  Fluorine atom ahorow a ɛbɔ ho ban : Fluorine atɔm akɛse a ahoɔden bɔne wom no ayɛ ma kɛse, na ɛyɛ adwuma sɛ akode a ɛyɛ den a ɛkata carbon nkɔnsɔnkɔnsɔn a ɛwɔ mu no ho koraa. Saa akwanside yi mma nnuru dodow no ara (a oxygen ka ho) ntumi nkɔ carbon nkɔnsɔnkɔnsɔn no mu na esiw oxidation nneyɛe a ɛho hia ma ɔhyew no ano denneennen.

2. Nneɛma a Ɛporɔw a Ɛnyɛ Ɔhyew: Depolymerization Sen sɛ Ɛbɛhyew

·  Chain scission before oxidation : Wɔ ɔhyew a ɛkɔ soro ase no, carbon-carbon (C–C) nkitahodi a ɛyɛ mmerɛw kakra wɔ PTFE mu no bubu ansa na C–F abɔ. Molekyule nkɔnsɔnkɔnsɔn fi ase porɔw ansa na oxygen atumi de ne ho ahyɛ nneyɛe mu.

·  Ade titiriw ne monomer : Sɛ ɛbubu a, PTFE titiriw fa depolymerization , gyae tetrafluoroethylene (C2F4) monomers fi nkɔnsɔnkɔnsɔn awiei. Ade no yɛ nwini mmom sen sɛ ɛbɛhyew denneennen a ɛma ɔhyew ne mframa a etumi hyew pii fi mu ba.

·  Gas-phase barrier effect : C2F4 gas a efi depolymerization mu no yɛ den sen mframa na ɛtra bɛn soro, na ɛyɛ bere tiaa mu mframa a ɛma oxygen dodow yɛ mmerɛw na esiw ɔhyew ano bio.

3. Dwuma a Glass Fiber Substrate di a ɛboa

PTFE ntama a ɛyɛ hyew kɛse yɛ ade a wɔabom ayɛ denam PTFE a wɔde kata ahwehwɛ nhama ntama so. Glass fiber ankasa yɛ ade a ɛnyɛ abɔde a nkwa wom a entumi nhyew. Sɛ́ nnompe a ɛwɔ ɔdan no mu no, ɛhwɛ hu sɛ sɛ mpo PTFE a ɛwɔ soro no di dwuma koraa wɔ ɔhyew a ano yɛ den ase a, ade no nwene anaasɛ ɛntɔ te sɛ plastic a ɛho tew, na ɛma ɔdan no mudi mu kura na esiw ogyaframa no ntrɛwmu ano.

Ɛsɛ sɛ wosi so dua sɛ PTFE yɛ nea ogya ntumi nhyew , ɛnyɛ nea entumi nhyew koraa.Sɛ wɔma ɛyɛ hyew boro nea ɛyɛ hyew (327°C) na ɛkɔ so daa a, ɛporɔw na ɛma wusiw a awuduru wom fi mu. Ɛtaa gyina ɔhyew a ɛkɔ 260°C ano bere tenten na ɛkɔ so gyina hɔ bere tiaa bi wɔ 300–360°C.

Porɔw wɔ ogya a ɛda hɔ mu : Sɛ wɔde to ogya a wɔabue mu tẽẽ (a ɛboro ne hyew a ɛporɔw so koraa) a, PTFE a ɛwɔ mu no porɔw, nanso adeyɛ no mma ɔhyew anaa nneɛma a ɛhyew a ɛdɔɔso mma ogya a ɛbɛkɔ so atra hɔ. Sɛ wɔde ka ahwehwɛ nhama a wɔde gyina so no ho a, ogyaframa ntumi ntrɛw nkɔ so.

Sɛ yɛbɛbɔ no mua a, PTFE ntama a ɛyɛ hyew kɛse no ntumi nhyew efisɛ wɔayɛ ne ade titiriw PTFE no molecule mu sɛnea ɛbɛyɛ a ɛbɛko atia ɔhyew .Nnuru a ɛwɔ ahoɔden kɛse, akwan soronko a ɛporɔw, ne ahwehwɛ nhama nnompe a entumi hyew no bom yɛ akwanside a emu yɛ den a ogya ntumi nkɔ mu.
