Teflon rhaub yog siv dav hauv cov nroj tsuag tshuaj

Lub tshuab rhaub Teflon tsis tuaj yeem tshem tawm hluav taws xob cua sov raj ntawm cov kua thaum lub sij hawm cua sov. Tom qab hluav taws xob hluav taws xob, lub tshuab hluav taws xob cua sov yuav tsum tau txias rau ob peb feeb. Tsis tas li ntawd, txhua leej txhua tus yuav tsum xyuas kom meej tias cov hluav taws xob cua sov ib feem ntawm Teflon rhaub yuav tsum tau tsau rau hauv cov kua dej aqueous, txwv tsis pub cov hluav taws xob cua sov raj yuav raug hlawv thiab puas. Thaum lub sij hawm tsim cov txheej txheem, nws yog ib qho tsim nyog yuav tsum tau ntxiv cov tshuaj ua kua hauv lub sijhawm kom tswj tau qhov ntsuas ntawm cov kua qib ntsuas. Nws muaj cov nyhuv tiv thaiv lub cav tsheb kom tsis txhob ntub. Yog tias lub cav tsheb tau muab tso rau lub sijhawm ntev, nws yog siv los tshem tawm cov dej noo ntawm lub tshuab cua sov thiab tsis txhob ua rau lub cav tsheb puas thaum kho lub qhov hluav taws xob. Nws tseem yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov av xaim tsis kam ntawm lub cev muaj zog ib txwm tswj hwm tus nqi siab los tiv thaiv kev hloov pauv hauv kev khiav hauj lwm kub ntawm lub cev muaj zog nyob rau hauv ib puag ncig cov av noo siab, uas yuav ua rau muaj kev sib txuam vim dej tsub zuj zuj. Yog li ntawd, cov txheej txheem sab hauv winding yog ntub thiab txias, thiab cov txheej txheem rwb thaiv tsev raug txo; Yog li ntawd, yog tias muaj qhov xwm txheej zoo li no, nws tuaj yeem tiv thaiv lub cev muaj zog los ntawm overheating thiab ua rau qee qhov kub thiab txias, ua rau cov rwb thaiv tsev laus. Qee qhov kev ntsuas yuav tsum tau ua kom txo qis kev ua haujlwm ntawm lub cev muaj zog. Kev ua haujlwm ntawm Teflon rhaub yog txhawm rau tiv thaiv lub cav tsheb los ntawm kev pib ib txwm vim muaj qhov kub thiab txias (tsuas yog siv rau hauv thaj chaw uas muaj qhov kub qis dua). Txhua yam khoom muaj nws lub ntsiab lus, thiab hauv peb lub neej niaj hnub, muaj ntau yam khoom tseem ceeb thiab cov khoom. Hauv cov ntawv thov kev lag luam, tseem muaj ntau yam khoom siv hauv kev lag luam uas tau ua lawv lub luag haujlwm hauv ntau qhov chaw, thiab tib yam siv rau kev hloov hluav taws xob ntawm Teflon. Niaj hnub no, cia peb saib cov yam ntxwv ntawm Teflon tshav kub exchangers? Yog koj txaus siab, cia peb nyeem txuas ntxiv ua ke.
Teflon muaj cov txiaj ntsig zoo uas lwm cov ntaub ntawv tsis muaj, tshwj xeeb tshaj yog cov yam ntxwv ntawm qhov kub thiab txias thiab corrosion kuj ntawm Teflon raw cov ntaub ntawv siv nyob rau hauv tshav kub exchangers. Qhov no tau ua rau muaj kev siv dav dav ntawm Teflon heat exchangers hauv teb xws li tshuaj nroj tsuag, acid pickling thiab passivation, electroplating txheej txheem, tshuaj, thiab kev kho mob anodizing. PTFE txias kub alternate heat exchanger / PTFE Teflon tshav kub exchanger muaj tsis tshua muaj zog corrosion kuj thiab aging kuj ua hauj lwm. Vim nws cov cua kub zoo heev, nws yog qhov tsim nyog rau ob qho tib si chav cua kub exchangers thiab boiling dej cua sov; Tus yuam sij rau Teflon tshav kub exchangers yog lawv zoo heev corrosion kuj. Vim hais tias polytetrafluoroethylene yog cov khoom siv tshuaj lom neeg tsis zoo, nws tuaj yeem ua haujlwm hauv txhua qhov xov xwm tshwj tsis yog cov khoom siv kub kub xws li fluorine, molten alkaline ntiaj teb hlau, hydrogen trifluoride chloride, thiab perfluorinated roj av. Piv txwv li: dilute hydrochloric acid, hydrochloric acid, hydrochloric acid, sodium cyanide, ammonium sulfate, glacial acetic acid, hydrochloric acid, sodium hydroxide, calcium hydroxide, naphthalene, benzene, xylene, sulfuric acid, xylene, ntau yam organic tov, ETC. Teflon raw cov ntaub ntawv tsis muaj kab mob, yog li lawv tsis nquag scaling. Vim hais tias ntawm cov tshuaj plasticity, du nto, refractive index thiab siab thermal expansion coefficient ntawm PTFE yeeb nkab, lub tshav kub conduction nto tsis yooj yim rau scale, uas zoo heev txo cov zaus ntawm cov khoom tu thiab tswj, thiab ua kom ib tug kuj ruaj khov thermal conductivity thiab kev tsim khoom. Kev sib tw nyob deb.
