Lub npe: PTFE xaws xov
Optimized Khoom: PTFE
Qhov hnyav: 200g-1000g
Specification: 400D-2700D
Xim: Dawb, Dub, thiab Customized
Daim ntawv thov:Nws feem ntau yog siv rau hauv cov kav dej, ntim, twj, li qub, thiab radar systems, cov khoom siv sib txuas lus siab, thiab cov khoom siv hauv xov tooj cua uas yuav tsum tau ua haujlwm siab.
Khoom ua haujlwm:Gasket sealing thiab lubricating cov ntaub ntawv ua haujlwm hauv ntau yam xov xwm.
1.Chemical tsis kam:
PTFE muaj tsis tshua muaj siab tiv thaiv tshuaj corrosion, xws li nyob rau hauv concentrated sulfuric acid, hydrochloric acid, thiab nitric acid.Txawm hais tias nws yog boiled hauv aqua regia, nws qhov hnyav thiab cov khoom tsis hloov pauv, thiab nws yuav luag insoluble hauv cov kuab tshuaj feem ntau, tsuas yog me ntsis soluble hauv peralkanes (li 0.1g / 100g) saum 300 ° C.
2. Huab cua tsis kam:
PTFE tsis nqus dej noo, tsis yog nplaim taws, thiab ruaj khov rau cov pa oxygen thiab ultraviolet rays, yog li nws muaj huab cua zoo heev.
3.Mechanical zog:
PTFE tswj cov khoom zoo heev hauv qhov kub ntawm -196 txog 260 ° C. Ib qho ntawm cov yam ntxwv ntawm perfluorocarbon polymers yog tias nws tsis ua nkig ntawm qhov kub thiab txias.Qhov ntom ntawm PTFE yog qhov loj, uas yog 2.14-2.20g / cm3, tsis tshua nqus dej, thiab qhov sib npaug ntawm qhov nqus dej tsawg dua 0.01%.
PTFE e yog ib hom mos mos thiab tsis muaj zog polymer, kev sib nrig sib attraction ntawm macro-molecules yog me me, thiab lub zog, hardness thiab lub zog me me, thiab nws yuav deform nyob rau hauv lub sij hawm ntev kev ntxhov siab.
