PTFE Yog Ib Cov Khoom Uas Muaj Cov Khoom Uas Muaj Zis Minimal

SOLVER POLYIMIDE | Updated: Apr 24, 2018

Cov qauv tshuaj ntawm PTFE yog hloov tag nrho hydrogen atoms hauv polyethylene nrog cov tshuaj fluorine.

Nyob rau hauv Teflon molecule, lub F atom masks nyiaj CC thiab cov nyiaj CF yog qhov ruaj khov. Nws tsis tawm tsam los ntawm tej yam tshuaj uas tsis yog xim alkali hlau thiab elemental fluorine.

Nyob rau hauv PTFE molecule, F F atom yog symmetrical, thiab ob lub ntsiab hauv CF yog cov bondage covalently. Yog tsis muaj lub tshuab hluav taws xob dawb hauv lub molecule thiab tag nrho cov molecule yog nruab nrab. PTFE muaj zoo dielectric zog vim PTFE twb tsis gram hauv nws cov qauv molecular, ces nws crystallinity yog siab. Vim hais tias PTFE muaj ib qho tshuaj fluorine uas muaj plhaub (outer fluid), nws muaj cov khoom tsis muaj zog thiab tsis muaj kev sib tsoo ntawm kev sib txhuam.

1. Rwb thaiv tsev: Nws tsis raug cuam tshuam los ntawm ib puag ncig thiab zaus, lub ntim tsis muaj peev xwm ncav cuag 1018 ohm • cm, qhov dielectric poob me me, thiab qhov tawg qhov hluav taws xob yog siab.

2, siab thiab kub tsis kam: Tej yam kub hloov me ntsis, ntau hom kub ntau, kev siv kub txog -190 ~ 260 ° C.

3, cov khoom siv lubricating: nrog cov me tshaj kev txhuam coefficient hauv yas, yog cov khoom uas tsis muaj roj-dawb lubrication cov khoom.

4, saum npoo tsis nplaum: paub cov khoom sib xyaw uas tsis tuaj yeem ua rau qhov chaw, yog ib hom ntawm lub zog ntawm cov khoom siv tsawg tshaj plaws.

5, tsis kam mus rau lub cev tsis muaj zog, ua rau cov hluav taws xob tsis muaj zog thiab tsis muaj permeability: ntev mus rau qhov chaw, qhov chaw thiab qhov kev ua haujlwm tsis hloov.

6. Incombustibility: Qhov ntsuas qhov ntsuas qhov qis yog qis dua 90.

7, tshuaj lom neeg ua hauj thiab huab cua tsis kam: Ntxiv rau lub molten alkali hlau, PTFE yuav luag dawb ntawm cov tshuaj corrosion. Piv txwv, nyob rau hauv concentrated sulfuric acid, nitric acid, hydrochloric acid thiab txawm rhaub hauv aqua regia, tsis muaj kev hloov hauv qhov hnyav thiab kev ua tau zoo, thiab yuav luag tsis muaj teeb meem nyob rau hauv tag nrho cov kuab tshuaj. Nws tsuas yog me ntsis soluble nyob rau hauv tag nrho paraffins (txog 0.1 g / 100 g) ntawm kub saum 300 ° C. PTFE tsis nqhis dej noo, tsis yog cov huab cua, thiab tsis tshua muaj kev ruaj khov rau cov pa thiab ultraviolet rays, yog li nws muaj huab cua zoo heev.

SOLVER POLYIMIDE polyimide yog ib yam kev kawm siab yam xws li tshuab yas. Nws tsis zoo xwb muaj thermal yav tom ntej, txhua yam, dielectric, stability seem, ua hauj corrosion thiab tawg los tiv thaiv kev, tab sis kuj muaj zoo machinability. Nws yuav tau zoo li tus los ntawm kev sib txawv xws li zoo li molding, extrusion, molding txhaj tshuaj thiab txhaj tshuaj....
