Ua ntej-Plating Surface Preparation under Harsh Chemical and Electrical Conditions
Ua ntej ib feem nkag mus rau hauv lub plating da dej, nws yuav tsum tau phais kom huv si. Acid electrocleaning siv cov kub, hluav taws xob uas muaj kua qaub los tshem tawm cov roj seem, oxides, thiab cov kab mob microscopic los ntawm cov hlau. Lub tshuab cua sov hauv theem no yog qhov sib xyaw ua ke ntawm qhov kub thiab txias, aggressive chemistry, thiab hluav taws xob tam sim no teb uas tuaj yeem ua kom qeeb degradation hauv cov khoom siv hluav taws xob zoo li qub.
Nyob rau hauv xws li ib puag ncig, lub rhaub ua ib qho tseem ceeb ntawm kev ntseeg siab es tsis yog ib qho yooj yim thermal qhov chaw.
Acid Electrocleaning Txheej Txheej Txheej Txheem thiab Cov Cuab Yeej Xav Tau
Electrocleaning tanks feem ntau ua haujlwm nrog sulfuric lossis hydrochloric acid-raws li kev daws teeb meem ntawm 60-70℃. Cov khoom yog biased hluav taws xob, ua raws li anode lossis cathode nyob ntawm cov txheej txheem chemistry. Qhov kev txiav txim ntawm electrochemical no txhim kho kev tshem tawm cov kab mob, tab sis qhia txog txoj hauv kev tam sim no thiab qhov chaw muaj peev xwm sib txawv hauv lub tank.
Yog li ntawd, ib puag ncig yog ob qho tib si tshuaj thiab hluav taws xob ua phem. Hlau-cov cua sov sheathed tej zaum yuav raug kev cuam tshuam los ntawm corrosion, pitting, thiab galvanic kev sib cuam tshuam nyob rau lub sij hawm, tshwj xeeb tshaj yog nyob rau hauv tam sim no txoj kev to. Txawm tias stainless hlau tuaj yeem maj mam degrade nyob rau hauv kev sib xyaw acid raug thiab hluav taws xob kev ntxhov siab.
A PTFE rhaub acid electrocleanerconfiguration yog dav saws vim hais tias cov PTFE sheath muab tshuaj inertness thiab hluav taws xob rwb thaiv tsev, cais cov cua sov caij los ntawm cov txheej txheem ib puag ncig.
Qhov zoo ntawm PTFE Immersion Heaters hauv Electrocleaning Systems
PTFE immersion heaters yog siv los tswj cov txheej txheem ruaj khov yam tsis muaj kev cuam tshuam rau kev sib kis lossis electrochemical instability.
Cov txiaj ntsig tseem ceeb ntawm kev ua haujlwm muaj xws li:
Tshuaj tiv thaiv:PTFE tseem nyob ruaj khov nyob rau hauv sulfuric thiab hydrochloric acid sib tov ntawm cov electrocleaning kub.
Hluav taws xob rwb thaiv tsev:Lub zog dielectric siab tiv thaiv tam sim no los ntawm cov cua kub hauv chav da dej.
Contamination tswj:Tsis muaj hlau ion tso tawm tshwm sim, tiv thaiv qhov tsis xws luag ntawm cov khoom kho.
Txheej txheem stability:Cov cua kub tsis sib xws txhawb nqa cov tshuaj tiv thaiv electrochemical zoo ib yam thoob plaws lub tank.
Nyob rau hauv electrocleaning kab, lub rhaub yuav tsum ua hauj lwm raws li ib tug passive thermal ntaus ntawv, unaffected los ntawm lub electrochemical circuit.
Daim Ntawv Ceeb Toom Hluav Taws Xob
Kev cog lus hauv av kom zoo thiab kev sib cais hluav taws xob yog qhov tseem ceeb hauv PTFE lub tshuab hluav taws xob siv hauv cov tshuab hluav taws xob. Lub tshuab cua sov hauv av yuav tsum tau tswj xyuas nruj raws li qhov chaw nyab xeeb thiab yuav tsum tsis txhob ua ib feem ntawm txoj kev electrocleaning tam sim no.
Txoj kev khiav tam sim no los ntawm txoj hauv kev tsis xav tau tuaj yeem ua rau thaj chaw pitting ntawm workpieces lossis kev ua haujlwm tsis tu ncua. Kev sib cais hluav taws xob ntawm cov hluav taws xob hluav taws xob thiab cov hluav taws xob hluav taws xob hluav taws xob yog li ntawd suav tias yog qhov tsim nyog tsim nyog.
Kev txiav txim siab ua haujlwm
Txawm hais tias PTFE cov cua sov muab cov tshuaj muaj zog thiab hluav taws xob sib cais, kev tsim qauv yuav tsum tseem suav nrog:
Uniform tshav kub faib kom tsis txhob muaj overheating hauv zos
Kev daws teeb meem txaus los tiv thaiv thermal stratification
Kev xaiv watt ntom ntom kom raug los tiv thaiv sheath overheating ntawm lub rhaub dej
Kev tswj qhov kub thiab txias nyob rau hauv 60-70℃ntau yam yog feem ntau tswj xyuas siv lwm PID controllers txuas nrog corrosion-resistant RTD lossis thermocouple sensors.
Xaus
PTFE heaters sawv cev rau cov tshuaj tiv thaiv zoo rau cov kua qaub electrocleaning tshuab, xa cov khoom siv hluav taws xob tswj tau thaum cov tshuaj tsis muaj zog thiab hluav taws xob cais tawm ntawm cov txheej txheem. Lawv txoj kev siv txo qis kev pheej hmoo ntawm kev sib kis thiab txhawb kev ruaj ntseg electrochemical kev ua tau zoo hauv kev thov ua ntej -plating ib puag ncig.
Hauv kev ua hluav taws xob hluav taws xob, lub tshuab cua sov yuav tsum ua haujlwm raws li cov khoom siv hluav taws xob - muab lub zog tsis muaj kev cuam tshuam rau txoj hauv kev tam sim no uas txhais cov txheej txheem chemistry.
