Polytetrafluoroethylene qauv

Cov qauv theem pib ntawm polytetrosraethylene
Polytetrafluoroethylene (PTFE) yog polymer tsim los ntawm cov polymerization ntawm tetrafluoroethylene monomers. Nws cov mis nyuj yog (c2f4) n. Chav theem pib ntawm cov khoom no yog qhov rov ua dua - cf2-cf2-cf2-cf2-cf2-cf2-cf2-cd2-cf2-cf2-cf2-cf2-cm2-cf2

Tshuaj lom neeg cov khoom ntawm polytetrosraethoroethylene
PTFE muaj cov tshuaj ruaj khov zoo thiab tiv taus corrosion los ntawm cov muaj zog acids, hauv paus, thiab cov kuab tshuaj. Nws muaj lub thermal decomposition kub tshaj 415 Degree, tus Vicat muag muag taw tes ntawm 110 degree, thiab cua sov distortion kub ntawm 55 degree.

Lub cev cov yam ntxwv ntawm polytetrosraethoroethylene
PTFE muaj qhov qis coefficient ntawm kev sib txhuam thiab lub zoo zoo. Nws muaj qhov ntsuas tsis tau ntawm 1.37, lub siab kub, ib qho nyuaj ntawm 58, kev tawm tsam ntawm 10 ^ 1 ω ω0.167 - 0.300 w / min k.

Cov ntawv thov ntawm polytetrosraethoroethylene
Vim nws cov khoom tau zoo heev, polytetrosraTrene yog siv rau ntau qhov chaw xav tau rau cov acids, alkalis, thiab cov kuab tshuaj organic. Tsis tas li ntawd, nthuav dav polytetrafluoroethylene (Eptfe), yog siv rau hauv kev tsim cov khoom kho mob xws li cov hlab ntshav zoo nkauj thiab cov ntshav siab.
