PTFE Molecular Structure ne Ne Su a Ɛyɛ Paara

Sɛ́ adwumayɛfo fibea a wɔyɛ PTFE ntama a ɛyɛ hyew kɛse no, Jiangsu Aokai New Materials de adwumayɛfo nhumu brɛ wo. PTFE ntama a ɛyɛ hyew kɛse no fã titiriw ne Polytetrafluoroethylene (PTFE), a molecule nhyehyɛe yɛ (mathbf{-(CF_2-CF_2)_n-}). Fluorine atɔm na ɛkata carbon nkɔnsɔnkɔnsɔn titiriw no ho koraa. Saa su abiɛsa a ɛkorɔn yi ne PTFE molecule ahorow no nhyehyɛe mu nneɛma a ɛwɔ gyinabea ahorow mu no hyia:

1. Excellent Non-stick Agyapade

Wonya fi ahoɔden a ɛba fam koraa a ɛwɔ soro, a wɔde fluorine atɔm a wɔde kyekyere akyi denneennen  ne molecule a ɛnyɛ polarity na ɛkyerɛ.

·  Fluorine atom ahorow a ɛbɔ ho ban kɛse: Fluorine na ɛwɔ electronegativity a emu yɛ den sen biara na ɛwɔ van der Waals radius kɛse. Wɔahyehyɛ fluorine atɔm ahorow no daa na ɛyɛ den sɛ nkuruwankuruwa wɔ carbon nkɔnsɔnkɔnsɔn no akyi, na ɛyɛ akorade a ɛyɛ den a ɛbɔ ho ban na ɛma ɛyɛ mmerɛw a fluorine wom koraa.

·  Ahoɔden a ɛyɛ mmerɛw wɔ molecule ahorow ntam: Ɛwom sɛ CF nkitahodi no yɛ polar denneennen de, nanso nhyehyɛe a ɛne ne ho hyia koraa no ma molecule nkɔnsɔnkɔnsɔn no nyinaa nyɛ polar. Tumi a ɛyɛ mmerɛw a ɛpete nkutoo na ɛwɔ molecule ahorow ntam, na ɛde ahoɔden a ɛba fam koraa ba wɔ soro (bɛyɛ 18 mN/m). Ɛkame ayɛ sɛ nneɛma biara ntumi ntrɛw anaasɛ ɛnbata PTFE no ani.

2. Acid & Alkali Corrosion a ɛyɛ den a ɛko tia

Wonya fi nnuru bond inertness a ɛkorɔn yiye, a wɔde CF bond ahoɔden a ɛkorɔn  ne steric shielding effect na ɛkyerɛ.

·  CF nkitahodi a ahoɔden kɛse wom: CF nkitahodi no wɔ nkitahodi ahoɔden a ɛkorɔn yiye (bɛyɛ 485 kJ/mol), ɛyɛ den koraa sen CH ne CC nkitahodi, na ɛyɛ den yiye sɛ wobebubu.

·  Ahobammɔ a edi mũ a wɔde bɔ ho ban: Fluorine atom akorade a ɛyɛ den no kata carbon nkɔnsɔnkɔnsɔn nnompe no so koraa, na ɛmma ions a ɛporɔw ntumi nkɔ carbon nkɔnsɔnkɔnsɔn a nnuru yɛ mmerɛw no mu. Ɛma honam fam ne nnuru a ɛnyɛ adwuma ahobammɔ abien hu.

3. Electrical Insulation a ɛkorɔn sen biara

Wonya fi polarizability a ɛba fam koraa ne zero free charges, a wɔde molecule symmetry  ne electron binding effect a emu yɛ den na ɛkyerɛ.

·  Integral non-polar structure: Ɛmfa ho sɛ CF bonds no local polarity wɔ hɔ no, fluorine atom ahorow a wɔahyehyɛ no pɛpɛɛpɛ koraa wɔ carbon chain no afã abien no nyinaa ma ɛkame ayɛ sɛ zero total molecular dipole moment, na ɛma PTFE yɛ ade a ɛnyɛ polar a ɛtaa ba.

·  Ɛlektrɔn a wɔakyekyere no denneennen: Fluorine atɔm ahorow no ɛlɛtrɔnik bɔne a emu yɛ den no twetwe ɛlɛtrɔnik mununkum denneennen kɔ fluorine atɔm so. Ɛlektrɔnik a ɛwɔ molecule ahorow mu no ntumi ntu anaasɛ ennye n’ahome wɔ anyinam ahoɔden a ɛwɔ abɔnten ase, a enni ahoɔden a ɛde ahoɔden kɔ. Enti, PTFE hoahoa ne ho sɛ ultra-low dielectric loss ne kɛse breakdown ahoɔden.

Tɔfabɔ

Fluorine atɔm a wɔde kyekyere carbon nkɔnsɔnkɔnsɔn ho koraa, CF covalent nkitahodi ntiantiaa a ahoɔden kɛse wom, ne molecule nhyehyɛe a ɛnyɛ polar a ɛyɛ pɛpɛɛpɛ koraa bom boa ma PTFE yɛ adwuma soronko: ɛnyɛ nea ɛyɛ nnam, ɛko tia nsɛe ne anyinam ahoɔden a ɛkorɔn a wɔde siw ano.
