Vim li cas PTFE fluoride tau dhau los ua ntau dua thiab nrov dua nyob rau hauv teb hluav taws xob cua sov

Ntawm ntau yam plastics, fluororesins muaj cov khoom tshwj xeeb. Piv txwv li, lawv muaj kev zam hluav taws kub tsis kam, qis {{{1} dej tsis kam, tshuaj rwb thaiv tsev, thiab siab {2} {zaus kev ua tau zoo. Lawv kuj tseem tsis muaj kev tshwj xeeb tsis- cov nplaum thiab qis- kev txhuam cov khoom sib txhuam. Cov khoom zoo tshaj plaws tau ua rau lawv siv ntau thoob plaws hauv kev siv tshuaj, kev lag luam hluav taws xob, tab sis kuj tseem muaj ntau cov ntawv thov, los ntawm Aerospace rau cov khoom hauv tsev neeg.

PTFE (polytetrafluoroethylene), hu ua "King ntawm plastics," yog ib tug sawv cev fluorocarbon polymer. PTFE muaj cov qauv siv tshuaj lom neeg nyob rau hauv uas txhua yam hydrogen atoms hauv polyethylene rems, uas ua rau muaj kev sib tw ntev ntawm 2 txog 10 lab. Vim yog cov tshuaj muaj zog ntawm cov tshuaj fluorine atoms hauv fluorocarbon polymers, lawv nthuav tawm cov cua sov thiab tshuaj piv rau lwm yam uas zoo sib xws. Qhov ntau fluorine atoms hauv cov molecule, ntau tshaj cov lus tshaj tawm no tau dhau los. Yog li ntawd, PTFE yog qhov khoom lag luam fluorinated zoo tshaj.

Thaum Tshav Kub Kub Ua

PTFE tuaj yeem siv txuas ntxiv ntawm qhov kub tsis tu ncua txog 260 degree, thiab tuaj yeem ua siab ntev dua nyob rau lub sijhawm luv luv. Nws tseem ua pov thawj zoo tshaj plaws - kub tsis kam. Yog li ntawd, hluav taws xob thiab cov xov hluav taws xob, cov xov hlau, thiab lwm yam khoom siv los ntawm PTFE Dispersions tau siv dav.

Tshuaj Tshuaj Muaj Zog

PTFE cov khoom pov thawj zoo heev rau cov tshuaj uas ib txwm siv. Thaum tej zaum nws yuav rhuav tshem kev ua haujlwm hnyav, xws li cov hlau tsis txaus ntseeg, nws pheej siv tshuaj acidic thiab alkaline oxidants, thiab tsis yaj nyob rau hauv kev sib cuag nrog cov organic sib txuas. Yog li ntawd, PTFE tau siv dav hauv cov ntawv thov tshuaj xws li cov ntaub pua plag, cov kaus mom braided, gaskets, tes tsho, thiab shrink tubing.

Cov Khoom Siv Hluav Taws Xob

PTFE cov qauv molecular yog tsis - polar, ua rau nws zoo tagnrho rau high- zaus rwb thaiv tsev. PTFE tsis tsuas yog muaj qhov kub thiab txias ntau tab sis tseem tswj hwm qhov qis thiab ruaj khov dielectric constant thiab dielectric poob thoob plaws ntau. Tsis tas li ntawd, nws yog tsis muaj kev cuam tshuam los ntawm lub hnub ci thiab av noo. PTFE siv nyob rau hauv dav hlau, xaim hluav taws xob, nyias coaxial cables, kev tswj hwm cables, rwb thaiv tsev lub tes tsho, thiab qhwv hlau.

Corrosion Kuj

Nyob rau hauv ib txwm xwm txheej, PTFE muaj cov khoom tsis tshua muaj kev sib txhuam coefficient thiab tsis - swb. Tsis tas li ntawd, nws yog heev tsis yog-}}}} Tsis muaj- adherent rau tej khoom. Yog li ntawd, PTFE tuaj yeem siv rau hauv cov kav dej rau thauj cov kua dej viscous, nrog rau hauv Automotive thiab Machinery Industries.

Yog li, PTFE muaj ntau cov kev siv. Vim nws cov hluav taws xob zoo, PTFE yog zoo -} haum rau insulating xov hlau. Nws kuj tseem muaj kev kub kub zoo thiab tshuaj lom neeg. Cov qauv piv txwv muaj xws li: cov xov hlau hluav taws xob rau cov dav hlau, foob pob ua ntxaij, thiab cuaj zeej; Cov xov hlau rau hluav taws xob cov kev hloov pauv hluav taws xob thiab cov tsheb thauj khoom; xaim rau ntau cov twj siv hluav taws xob; siab - cov xov hluav taws kub; Thiab nyob ze Generators, hluav taws xob tshuab hluav taws xob, thiab cov kav hlau.
