Electroplating dej khib nyiab yog qhov nruab nrab nyuaj heev. Yuav xaiv li cas aflow meter? Vim nws cov hluav taws xob conductivity, electromagnetic flowmeter yog thawj qhov kev xaiv rau kev ua haujlwm zoo xws li qhov tseeb thiab kev ntseeg siab. Yog li yuav ua li cas xaiv electrodes thiab hauv ob sab phlu?
Ua ntej ntawm tag nrho cov, peb yuav tsum to taub dab tsi yog electroplating wastewater? Qhov sib xyaw ntawm electroplating dej khib nyiab yog qhov nyuaj heev. Ntxiv nrog rau cyanide (CN-) cov dej khib nyiab thiab cov kua qaub-puag cov dej khib nyiab, cov dej khib nyiab hnyav hlau yog cov dej khib nyiab hauv kev lag luam electroplating. Raws li kev faib tawm ntawm cov hlau hnyav uas muaj nyob hauv cov dej khib nyiab hnyav, feem ntau tuaj yeem muab faib ua chromium (Cr) cov dej khib nyiab, nickel (Ni) cov dej khib nyiab, cadmium (Cd) cov dej khib nyiab, tooj liab (Cu) cov dej khib nyiab, zinc (Zn) cov dej khib nyiab, Kub (Au) dej khib nyiab, nyiaj (Ag) dej khib nyiab, thiab lwm yam. Feem ntau, dej yog acidic, tab sis ib qho me me yog alkaline. Cov ntsiab lus ntawm cov hlau hnyav sib txawv nrog cov surfactants, brighteners, thiab cov txheej txheem ntau lawm.
Hauv lwm lo lus, nws tsis ruaj khov.
Ua ntej tshaj plaws, peb tuaj yeem xaiv polytetrafluoroethylene (PTFE) ua cov hauv ob sab phlu electromagnetic flowmeter. Vim tias nws zoo heev corrosion thiab kub tsis kam, nws tuaj yeem tiv taus yuav luag txhua yam tshuaj lom neeg, suav nrog cov concentrated nitric acid thiab aqua regia.
Qhov thib ob, xaiv qhov kev xaiv ntawm electrode, koj tuaj yeem xaiv tantalum (Ta) electrode, vim nws muaj zog corrosion kuj, tuaj yeem tiv taus corrosion ntawm yuav luag tag nrho cov tshuaj lom neeg tsuas yog hydrofluoric acid.
Lub HHDelectromagnetic flowmetertsim los ntawm Huahai yog ib qho cuab yeej induction uas ntsuas qhov ntim ntawm cov khoom siv hluav taws xob hauv lub raj raws li Faraday txoj cai ntawm electromagnetic induction. Nws siv ib leeg-chip embedded thev naus laus zis kom ua tiav digital excitation. Nyob rau tib lub sijhawm, CAN lub tsheb npav yog siv rau ntawm electromagnetic flowmeter. Nws yog ib qho kev pib hauv tsev thiab nws cov thev naus laus zis tau mus txog qib ua hauv tsev.
