PTFE mesh yog cov khoom siv mesh ua los ntawm polytetrafluoroethylene (PTFE). Nws muaj ntau yam khoom zoo heev:
1. Kub siab ua haujlwm:PTFE mesh siv tau rau ntau qhov kub thiab txias. Nws tuaj yeem ua tau zoo ntawm -180 ℃ thiab 260 ℃, uas ua rau nws muaj txiaj ntsig zoo rau qee qhov chaw kub xws li kev lim dej thiab kev tiv thaiv. Piv txwv li, hauv cov khoom siv lim roj flue ntawm qee lub cub tawg kev lag luam,PTFE meshtuaj yeem tiv taus qhov cuam tshuam ntawm cov pa roj kub siab yam tsis muaj kev hloov pauv lossis ua puas tsuaj ntawm qhov kub siab zoo li cov ntaub ntawv ib txwm muaj.
2. Kev ruaj khov tshuaj lom neeg:Nws tsis tshua muaj tshuaj lom neeg raug xeb. Txawm tias nws yog cov kua qaub muaj zog, cov alkali muaj zog lossis cov kuab tshuaj organic, nws nyuaj rau xeb PTFE mesh. Hauv kev lim dej ntawm kev lag luam tshuaj lom neeg, kev tiv thaiv cov thawv tshuaj lom neeg, thiab lwm yam, PTFE mesh tuaj yeem tiv thaiv kev xeb ntawm cov tshuaj lom neeg thiab txuas ntxiv lub neej ua haujlwm ntawm cov khoom siv. Piv txwv li, hauv cov txheej txheem tsim cov kua qaub sulfuric, PTFE mesh siv los lim cov kua qaub sulfuric yuav tsis raug xeb los ntawm cov kua qaub sulfuric thiab tuaj yeem ua tiav txoj haujlwm lim dej zoo.
3. Kev sib txhuam coefficient tsawg:Qhov saum npoo ntawm PTFE mesh yog du heev thiab muaj qhov sib txhuam tsawg heev. Qhov no ua rau nws ua tau zoo hauv qee qhov xwm txheej thov uas xav tau kev sib txhuam tsawg. Piv txwv li, hauv cov npog tiv thaiv ntawm qee qhov khoom siv kho tshuab, PTFE mesh tuaj yeem txo qhov sib txhuam ntawm cov khoom siv kho tshuab thiab cov npog tiv thaiv, txo qhov hnav, thiab txhim kho kev ua haujlwm zoo ntawm cov khoom siv kho tshuab.
4. Kev rwb thaiv hluav taws xob zoo:Nws yog ib yam khoom siv hluav taws xob zoo heev. Hauv kev tiv thaiv cov khoom siv hluav taws xob, kev tiv thaiv rwb thaiv tsev ntawm cov xov hlau thiab cov cables, thiab lwm yam., PTFE mesh tuaj yeem ua lub luag haujlwm zoo rwb thaiv tsev. Piv txwv li, hauv txheej rwb thaiv tsev ntawm qee cov cables high-voltage, PTFE mesh tuaj yeem tiv thaiv kev xau tam sim no thiab xyuas kom muaj kev nyab xeeb ntawm kev xa hluav taws xob.
5. Kev ua pa thiab dej permeability:Raws li cov txheej txheem tsim khoom sib txawv, PTFE mesh tuaj yeem ua rau cov khoom uas muaj qhov ua pa thiab dej permeability sib txawv. Hauv qee cov khaub ncaws ua pa thiab tsis muaj dej, PTFE mesh tuaj yeem thaiv cov dej nkag thaum tso cai rau cov pa dej hla dhau, ua rau tus neeg hnav qhuav thiab xis nyob.
Cov ntawv thov tshwj xeeb ntawm PTFE mesh hauv kev lag luam yog dab tsi?
PTFE mesh muaj ntau yam kev siv hauv kev lag luam tshwj xeeb. Nov yog qee qhov chaw siv tseem ceeb:
1. Kev lag luam tshuaj lom neeg
Kev ntxuav roj thiab lim kua: PTFE mesh feem ntau siv rau hauv cov tshuab lim tshuaj vim nws txoj kev tiv thaiv xeb zoo heev thiab cov khoom tsis lo. Nws tuaj yeem ua tau zoo rau cov xov xwm corrosive, high-viscosity, lom thiab ua rau muaj kev phom sij.
Kev tiv thaiv cov kav dej thiab cov khoom siv: Cov ntaub ntawv PTFE yog siv los tsim cov kav dej, cov li qub, cov twj tso kua mis thiab cov foob kom tiv thaiv cov khoom siv los ntawm kev xeb los ntawm cov tshuaj lom neeg.
2. Kev lag luam khoom noj thiab tshuaj
Kev lim cua thiab kua: PTFE mesh tsis muaj tshuaj lom, tsis muaj ntxhiab thiab yooj yim ntxuav. Nws yog dav siv rau hauv kev lim cua hauv cov chaw ua zaub mov thiab kev lim kua hauv cov txheej txheem tsim tshuaj.
Cov txheej txheej thiab cov ntsaws ruaj ruaj ntawm cov khoom siv: Hauv cov txheej txheej sab hauv thiab cov ntsaws ruaj ruaj ntawm cov khoom siv ua zaub mov, cov ntaub ntawv PTFE ua kom muaj kev nyab xeeb ntawm cov zaub mov thiab cov khoom siv ruaj khov.
3. Kev tiv thaiv ib puag ncig
Kev kho cov roj khib nyiab thiab kev kho cov dej phwj tuaj: PTFE mesh siv dav hauv kev kho cov dej phwj tuaj thiab kev kho cov roj khib nyiab, thiab tuaj yeem lim cov dej khib nyiab thiab cov roj khib nyiab uas muaj cov tshuaj corrosive heev xws li fluoride thiab chloride.
Kev tswj cov pa luam yeeb hauv kev lag luam: Cov hnab lim PTFE ua tau zoo hauv kev lim pa luam yeeb kub siab hauv kev lag luam xws li kev sib xyaw hlau, kev tsim cov cement thiab kev tsim hluav taws xob thermal. Lawv tuaj yeem tiv taus qhov kub siab txog li 260 ° C, thiab muaj kev lim dej raug thiab kev ua haujlwm tu zoo.
