Kev ntsuas ultrasonic ntawm cov dab dej plating no muab kev rov ua dua siab, thiab yog tsim rau ob qho tib si kev ua haujlwm galvanizing tas mus li thiab ua ke.
Kev ntsuas hauv qhov chaw puas tuaj yeem tiv thaiv cov teeb meem plating uas tshwm sim ntau?
Yog—kev siv cov txheej txheem ntsuas qhov ceev hauv qhov chaw ua rau pom tau sai thiab kho tau qhov sib txawv ntawm cov ntsuas dej uas ua rau muaj qhov tsis zoo ntawm cov plating. Cov neeg ua haujlwm teb rau qhov hloov pauv ntawm qhov ceev hauv lub sijhawm tiag tiag, tiv thaiv cov teeb meem xws li:
- Kev tsim cov khib nyiab los ntawm cov khoom tsis huv uas yaj ntau dhau.
- Cov txheej txheem tsis sib xws los ntawm cov tshuaj sib xyaw tsis sib xws.
- Kev tsis ruaj khov hauv chav dej vim yog qhov kub thiab txias lossis kev hloov pauv tshuaj lom neeg.
Cov cuab yeej ntsuas txheej txheem xws li ultrasonic density meters thiab online XRF devices ua rau muaj kev tswj hwm qib no, txhim kho kev ntseeg siab ntawm lub zinc bath thiab tiv thaiv qhov zoo ntawm cov txheej. Cov kev tshawb fawb hauv cov tsheb thiab marine lees paub tias kev saib xyuas lub sijhawm tiag tiag txo qhov tshwm sim ntawm cov plating defects, txhawb kev tiv thaiv corrosion, thiab txo qis kev ua haujlwm kim.
Yuav tsum tau saib xyuas qhov ceev ntawm cov zinc plating hauv da dej ntau npaum li cas?
Rau cov khoom ntau lossis tseem ceeb, kev soj ntsuam qhov ceev ntawm cov khoom siv xws li Lonnmeter ultrasonic density meter yog qhov zoo tagnrho. Qhov no ua kom ntseeg tau tias txhua qhov kev hloov pauv raug kuaj pom thiab kho tam sim ntawd. Qhov twg kev soj ntsuam tsis tu ncua ua tsis tau, kev ntsuas tsis tu ncua - txawm tias yog tes lossis tsis siv neeg - raug pom zoo. Zaus yuav tsum phim qhov muaj zog ntawm kev tsim khoom, qhov loj ntawm lub dab dej, thiab qhov zoo ntawm cov khoom xav tau. Cov txheej txheem ntsuas tsis siv neeg uas koom ua ke nrog cov kev tswj hwm ntawm cov nroj tsuag tuaj yeem tswj hwm kev kuaj xyuas ntau zaus, thaum kev kuaj xyuas tes tsis tu ncua yuav txaus rau kev ua haujlwm me me, yog tias cov kev tswj hwm tseem nruj kom tswj tau qhov ruaj khov ntawm lub dab dej thiab cov khoom.
