PTFE Molecular Structure thiab Nws Cov Khoom Zoo heev

Raws li cov kws tshaj lij kev tsim khoom ntawm PTFE cov ntaub ntawv kub kub, Jiangsu Aokai Cov Khoom Tshiab coj koj cov kev pom zoo. Cov khoom tseem ceeb ntawm PTFE kub-kub ntaub yog Polytetrafluoroethylene (PTFE), nrog cov qauv molecular ntawm (mathbf{-(CF_2-CF_2)_n-}). Cov pa roj carbon tseem ceeb yog qhwv tag nrho los ntawm fluorine atoms. Peb cov khoom zoo tshaj no sib raug rau cov qauv ntawm PTFE molecules ntawm ntau qib:

1. Cov khoom zoo heev uas tsis yog-stick

Muab los ntawm ultra-low nto zog, txiav txim siab los ntawm nruj txheej qhwv ntawm fluorine atoms  thiab molecular non-polarity.

·  High shielding nyhuv ntawm fluorine atoms: fluorine muaj zog tshaj electronegativity thiab ib tug loj van der Waals radius. Tsis tu ncua thiab ntom ntom nyob rau hauv ib lub kauv rau sab nraud ntawm cov pa roj carbon saw, fluorine atoms tsim lub plhaub tiv thaiv nruj thiab tsim kom muaj fluorinated du nto.

·  Tsis muaj zog intermolecular quab yuam: Txawm tias CF daim ntawv cog lus muaj zog polar, tag nrho symmetrical kev npaj ua rau tag nrho cov molecular saw tsis-polar. Tsuas yog tsis muaj zog dispersion rog nyob nruab nrab ntawm cov molecules, uas ua rau lub zog qis heev (kwv yees 18 mN / m). Yuav luag tsis muaj tshuaj yuav kis tau lossis ua raws li PTFE nto.

2. Muaj zog Acid & Alkali Corrosion Resistance

Muab los ntawm cov tshuaj lom neeg muaj zog heev, txiav txim siab los ntawm CF daim ntawv cog lus siab zog  thiab steric shielding nyhuv.

·  High-strength CF daim ntawv cog lus: CF daim ntawv cog lus nta ib tug ultra-siab daim ntawv cog lus zog (kwv yees. 485 kJ / mol), ntau ruaj khov tshaj CH thiab CC daim ntawv cog lus, thiab heev nyuaj rau tawg.

·  Complete shielding protection: The dense fluorine atom shell fully encapsulates the carbon chain skeleton, preventing corrosive ions from contacting the chemically vulnerable carbon chain. Nws paub txog dual lub cev thiab tshuaj tiv thaiv inert.

3. Superior Hluav taws xob rwb thaiv tsev

Muab tau los ntawm polarizability tsawg heev thiab xoom dawb xwb, txiav txim los ntawm molecular symmetry  thiab muaj zog electron binding nyhuv.

·  Cov qauv uas tsis yog-polar: Txawm tias lub zos polarity ntawm CF daim ntawv cog lus, tag nrho symmetrical kev npaj ntawm fluorine atoms ntawm ob sab ntawm cov pa roj carbon saw tau ua rau ib tug zero tag nrho molecular dipole lub sij hawm, ua PTFE ib yam khoom uas tsis yog-polar.

·  Tightly khi electrons: Lub zog electronegativity ntawm fluorine atoms rub electron huab nrees mus rau fluorine atoms. Cov hluav taws xob hauv cov molecules tsis tuaj yeem tsiv los yog so kom txaus nyob rau hauv ib qho hluav taws xob sab nraud, tsis muaj cov khoom siv hluav taws xob. Yog li, PTFE boasts ultra-low dielectric poob thiab siab tawg lub zog.

Cov ntsiab lus

Kev qhwv tag nrho ntawm cov saw hlau los ntawm fluorine atoms, luv luv high-zog CF covalent bonds, thiab tag nrho symmetrical non-polar molecular kev sib koom ua ke pab txhawb rau PTFE qhov kev ua yeeb yam txawv: tsis nplaum, corrosion kuj thiab hluav taws xob rwb thaiv tsev siab.
