PTFE puv Properties

PTFE(PolyTetraFluoroEthylene), fluorocarbon-raws li polymer, kuj paub los ntawm Dupont lub npe polymer® thiab kuj yog Furon lub npe Rulon®.Nws yog feem ntau siv nyob rau hauv nws cov nkauj xwb (unfilled) lub xeev.

Virgin PTFE muaj peev xwm nyob rau hauv nws tus kheej txoj cai, tab sis thaum muab ntxiv, nws txhim khu cov khoom hnav thiab deformation yam ntxwv kom siv tau tag nrho lawv cov khoom sib xyaw ua ke ntawm cov tshuaj, lub cev thiab hluav taws xob.

Cov qib uas tau sau ntau tshaj plaws thiab nws cov txiaj ntsig tau zoo dua qub yog:

iav Fiber(PTFE-GF): Ntxiv rau ntau qhov nyiaj (5% mus rau 40%), nce compressive zog, rigidity thiab hnav;txo creep thiab txias txaus;tsawg kawg nkaus rau cov khoom siv tshuaj thiab hluav taws xob.

Cov pa roj carbon(PTFE-CF): Ntxiv rau ntau qhov nyiaj (10% mus rau 35%), nce compressive zog, hardness, hnav, thiab load zog;zoo tshuaj tiv thaiv;Ntau hom thiab ntau npaum li cas ntawm cov pa roj carbon monoxide tuaj yeem muab ntxiv rau kev hloov pauv conductivity.

Graphite(PTFE-CGF): Ntxiv rau ntau qhov nyiaj (5% rau 15%), txo cov coefficient ntawm kev sib txhuam;txo qhov hnav thaum xub thawj;nce zog.

Molybdenum Disulfide(PTFE-MoS2): Ntxiv rau ntau qhov nyiaj (5% mus rau 15%), nce hardness, nruj, thiab hnav;tsawg kawg nkaus rau cov khoom siv tshuaj thiab hluav taws xob.

Hlau(PTFE-BR, PTFE-SSF): Cov khoom hnav zoo tshaj plaws, zoo kawg nkaus deformation muaj zog thiab zoo thermal conductivity.

Mineral:Mica ntxiv rau ntau qhov nyiaj (5% mus rau 10%), muab kev hnav zoo thiab ruaj khov ntxiv rau FDA ua raws.
