Galvanic Contamination Risks coj los ntawm Cua sov Mounting Cheebtsam
Qhov kev tsom xam no tsom mus rau precision hardware electroplating thiab hluav taws xob tivthaiv pretreatment ntau lawm kab. Immersion heater support brackets immersed in chemical liquid will corrode under long -ntev da dej raug. Kev sib txuam ntawm cov hlau bracket thiab kev daws teeb meem ua rau galvanic corrosion, tso cov hlau ions yaj mus rau hauv da dej. Feem ntau pawg neeg yuav khoom tsom mus rau qhov zoo ntawm lub rhaub dej kub thaum tsis quav ntsej cov khoom siv sib xws. Dissolved impurity ions tsim sediment thiab ua kom sib xyaw degradation ntawm immersion rhaub qhov chaw. Thaum cov kab mob tsis zoo hauv chav da dej thiab cov cua sov tso rau hauv ib feem ntawm kev laus tshwm sim, engineers feem ntau kho cov qauv tshuaj es tsis txhob hloov kho cov ntaub ntawv bracket, ua rau rov ua kom muaj kab mob thiab tsis ua hauj lwm ntxov ntxov.
Bracket Material Galvanic Contamination Performance Contrast Table
| Khoom siv bracket | Galvanic Corrosion Tendency | Hlau Ion Dissolution Rate | Bath Pollution Risk | Kev Pabcuam Lub Neej | Tsim nyog ua ib puag ncig |
|---|---|---|---|---|---|
| Ordinary carbon steel bracket | Heev | Ceev ceev | Siab heev | 4–8 lub hlis | nruj me ntsis tsis txhob ntub ua cov tso tsheb hlau luam |
| Standard stainless hlau bracket | Nruab nrab | Nruab nrab | Ib txwm | 11–15 lub hlis | Tsawg -chloride me me ntxuav tank |
| Titanium alloy bracket | Tsawg | qeeb | Tsawg | 18–23 lub hlis | Cov pa hluav taws xob hloov pauv hloov tank |
| PP / PVDF tsis yog - hlau bracket | Tsis tsim nyog | Yuav luag xoom | Tsawg kawg | 26–32 lub hlis | Siab -corrosion precision plating tank |
Tsim Mechanism ntawm Galvanic Contamination thiab Immersion Heater Degradation
Thaum hlau brackets yog immersed nyob rau hauv conductive ua kua, muaj peev xwm sib txawv ntawm cov ntaub ntawv hlau sib txawv, constituting galvanic cell loops. Lub bracket ua raws li lub anode thiab undergoes nruam corrosion, tso hlau cations mus rau hauv lub ua da dej. Cov impurity ions no koom nrog cov tshuaj tiv thaiv thiab tsim cov sludge insoluble, uas yooj yim adheres rau immersion rhaub plhaub. Sediment coverage tsim kaw crevices, tsim concentrated corrosive micro-ib puag ncig thiab ua kom fluoropolymer nto pitting. Tsis zoo li kev yaig ncaj qha rau ntawm lub tshuab tso cua sov, qhov kev puas tsuaj no tsis ncaj ncees, tshwm sim los ntawm cov pa phem tawm sab nraud ntawm cov cua sov, ua rau nws nyuaj rau kev taug qab thaum lub sij hawm niaj hnub tshuaj xyuas.
Qhov muag tsis pom kev xaiv cov khoom muaj kev phom sij nyob rau hauv kev xyaum ua haujlwm Retrofits
Ntau qhov chaw tsim khoom txais yuav tsawg- nqi carbon steel los yog cov hlau tsis muaj steel hlau rau immersion heater installation kom txuag tau thawj zaug peev. Xws li brackets corrode sai nyob rau hauv acidic los yog complex electrolyte tej yam kev mob. Tom qab da dej muaj kuab paug thiab immersion heater puas tshwm sim, cov neeg ua haujlwm tu tsuas yog hloov cov cua sov ua tsis tau tiav thiab ntxuav lub tank sludge. Yog tias tsis muaj kev txhim kho cov khoom siv kho dua tshiab, cov hlua khi tshiab yuav txuas ntxiv mus rau corrode thiab tso tawm impurities, ua rau lub voj voog tsis zoo ntawm cov pa phem dua thiab cov khoom siv poob.
Kev Sib Txuas Kev Xaiv Cov Qauv rau Immersion Heater Fixing Brackets
Cov txheej txheem thiab kev yuav khoom engineers yuav tsum xaiv cov khoom siv bracket raws li da dej muaj pes tsawg leeg thiab lub zog corrosion. Kev sib cuam tshuam qis-cov khoom siv tu lub tank tuaj yeem siv stainless hlau brackets los tswj tus nqi. Pa electroplating kab nrog nruab nrab corrosivity yog haum rau titanium brackets. High- cov txheej txheem plating precision uas yuav tsum tau tswj nruj impurity yuav tsum tau txais tsis yog-hlau PP lossis PVDF brackets. Cov khoom siv sib xyaw ua ke yuav tsum tau sau meej meej rau hauv cov khoom siv tshwj xeeb, tsis yog xaiv cov hlua khi yooj yim raws li tus nqi.
Ntev -Lub Sijhawm Ntau Lawm Cov txiaj ntsig ntawm Optimized Bracket Materials
Kev xaiv cov khoom siv bracket uas tsim nyog suppresses galvanic corrosion thiab txo cov hlau ion txawv teb chaws ntawm kev ua kua. Purified da dej ib puag ncig slows sediment tsim thiab relieves crevice degradation ntawm immersion rhaub qhov chaw. Kev ruaj ntseg da dej muaj pes tsawg leeg txo cov workpiece nto impurity tsis xws luag thiab txhim kho cov khoom yield. Tsawg zaus immersion heater tsis ua hauj lwm txiav kev siv nyiaj txiag thiab zam tsis tau cov khoom lag luam kaw uas tsis tau npaj tseg. Txawm hais tias siab - kev ua tau zoo ntawm cov khoom lag luam nce siab, cov kab ntau lawm tuaj yeem ua tiav cov nqi rov qab sai. Cov khoom siv sib txuam no siv tau rau txhua lub tank ua haujlwm ntub dej nruab nrog tshem tawm immersion rhaub fixtures.
