Taw qhia rau cov yam ntxwv ntawm Teflon Thaum tshav kub kub Exchangers

Tsis yog nplaum: Yuav luag txhua yam khoom tsis ua raws li polytetrafluoroethylene txheej. Cov yeeb yaj kiab kuj nthuav tawm cov khoom zoo uas tsis yog nplaum.
Kub kub tsis kam: PTFE txheej zaj duab xis muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam. Kev kub siab ua haujlwm tuaj yeem ncav cuag 300 degree hauv lub sijhawm luv luv, thiab tuaj yeem siv txuas ntxiv ntawm 240 degree thiab 260 degree. Nws muaj kev ruaj ntseg thermal stability thiab tuaj yeem ua haujlwm ntawm qhov kub thiab txias yam tsis muaj embrittlement, thiab yuav tsis yaj ntawm qhov kub thiab txias.
Kev ua haujlwm zawv zawg: PTFE txheej muaj qhov coefficient ntawm kev sib txhuam. Thaum lub load swb, qhov sib txhuam coefficient hloov, tab sis tus nqi tsuas yog {{0}} Ntawm 05 thiab 0.15.
Kev tiv thaiv dej noo: Cov tsos ntawm polytetrafluoroethylene txheej yog dawb los ntawm dej thiab roj, thiab nws tsis yooj yim rau daig hauv cov tshuaj thaum lub sijhawm ua haujlwm ntau lawm. Yog tias muaj cov av me me, nws tuaj yeem raug tshem tawm los ntawm kev txhuam yooj yim. Lub sijhawm luv luv, txuag lub sijhawm ua haujlwm, thiab txhim kho kev ua haujlwm zoo.
Hnav tsis kam: Nws muaj hnav tsis kam nyob rau hauv siab loads. Nyob rau hauv ib tug tej yam load, nws muaj ob qhov zoo ntawm hnav tsis kam thiab tsis adhesion.
Corrosion resistance: Polytetrafluoroethylene tsis raug rau cov tshuaj corrosion ntawm tag nrho cov, thiab tuaj yeem tiv taus qhov cuam tshuam ntawm molten alkali hlau, fluorinated media, thiab tag nrho cov acids muaj zog (xws li aqua regia), muaj zog oxidants, txo cov neeg ua haujlwm, thiab ntau yam organic solvents saum 300 degree tshwj tsis yog. rau hydrogen gas. Nws tuaj yeem tiv thaiv qhov chaw los ntawm txhua hom tshuaj corrosion.
Chemical Properties ntawm Teflon Thaum tshav kub kub Exchangers
Rwb thaiv tsev: Lub ntim kuj tuaj yeem ncav cuag 1018 ohms thiab tsis cuam tshuam los ntawm ib puag ncig thiab zaus · Cm, tsis tshua muaj hluav taws xob poob, siab tawg voltage.
Qhov kub thiab txias tsis kam: Nws muaj qhov cuam tshuam me ntsis ntawm qhov kub thiab txias, muaj qhov kub thiab txias ntau, thiab tuaj yeem siv tau ntawm qhov kub ntawm -190 mus rau 260. degree .
Nws tus kheej smoothness: qhov sib txhuam me me ntawm Z hauv cov yas yog cov ntaub ntawv tsis muaj roj zoo tagnrho.
Cov tsos mob uas tsis yog lo: Paub cov ntaub ntawv tsis tuaj yeem ua raws li qhov pom, thiab yog ib hom ntawm cov ntaub ntawv uas muaj qhov me me.
Kev tiv thaiv rau atmospheric laus, hluav taws xob tiv thaiv, tsis tshua muaj permeability: Tom qab lub sij hawm raug rau huab cua, qhov tsos thiab kev ua haujlwm tseem tsis hloov.
Non-flammable: Oxygen limiting Performance index qis dua 90.
Nyob rau hauv qhov kub tsis kam, Teflon tshav kub exchangers yog dav siv Corrosion tsis kam thiab siab viscosity kev lag luam. Lub sijhawm no, Z muaj zog Superacid fluridic acid kuj tuaj yeem siv los khaws cia.
