Dab tsi yog qhov txawv ntawm chrome plating thiab galvanizing?
Ua ntej, cov txheej txheem sib txawv
Qhov sib txawv tseem ceeb ntawm chromium plating thiab galvanizing hauv cov txheej txheem yog cov hlau ntsev thiab electrolytes siv sib txawv. Chromium plating siv chromate li electrolyte, thaum galvanizing siv zincate los yog zinc chloride ua cov electrolyte. Tsis tas li ntawd, qhov ceev tam sim no, qhov kub thiab txias, lub sijhawm thiab lwm yam txheej txheem ntawm chromium plating thiab galvanized plating kuj txawv.
Thib ob, kev ua haujlwm sib txawv
Kuj tseem muaj qee qhov sib txawv ntawm kev ua haujlwm ntawm chromium plating thiab galvanizing. Ua ntej tshaj plaws, lub hardness ntawm chromium plating txheej yog siab dua li ntawm galvanized, thiab nws hardness yuav txawv nyob rau hauv ib tug ntau yam ntawm 400 mus rau 1200HV, thaum lub hardness ntawm galvanized txheej feem ntau tsuas yog 70-100HV. Yog li ntawd, chrome-plated txheej tau zoo dua hnav tsis kam. Qhov thib ob, qhov corrosion kuj ntawm chromium plating txheej yog muaj zog dua li ntawm galvanized txheej, tshwj xeeb tshaj yog nyob rau hauv oxidizing nruab nrab, thiab corrosion kuj ntawm chromium plating txheej yog ntau dua li ntawm galvanized. Ntxiv dua thiab, cov tsos ntawm chrome txheej yog zoo nkauj dua li cov txheej galvanized, uas qhia ib tug silver-dawb xim hlau luster. Thaum kawg, txheej galvanized muaj qhov zoo weldability, thaum lub chrome plating txheej yuav tsum tau kho ua ntej vuam.
Thib peb, qhov sib txawv ntawm kev siv
Kev siv cov chromium thiab zinc plating kuj txawv. Chrome plating feem ntau yog siv los txhim kho qhov hnav tsis kam thiab corrosion tsis kam ntawm cov khoom ua haujlwm, haum rau cov kabmob hnyav thiab kev sib txhuam thiab hnav lub sijhawm, xws li tsheb, aviation, petrochemical thiab lwm yam kev lag luam. Cov hlau galvanized feem ntau yog siv los tiv thaiv xeb lossis xeb ntawm cov khoom ua haujlwm, tsim nyog rau kev tiv thaiv ntawm huab cua ib puag ncig thiab lwm yam corrosive media, xws li cov khoom siv hauv tsev, cov khoom siv hauv tsev, cov chaw thauj mus los thiab lwm yam lag luam.
Hauv cov ntsiab lus, chromium plating thiab zinc plating feem ntau yog siv cov thev naus laus zis kho mob, thiab muaj qee qhov sib txawv ntawm cov txheej txheem, kev ua haujlwm thiab kev siv. Hauv kev siv tswv yim, nws yog ib qho tsim nyog yuav tsum xaiv cov cuab yeej kho kom zoo nkauj raws li cov kev xav tau tshwj xeeb thiab ib puag ncig siv. Nyob rau tib lub sijhawm, nws tseem yuav tsum tau them sai sai rau kev saib xyuas tsis tu ncua thiab kev saib xyuas ntawm lub workpiece tom qab kev kho saum npoo kom ntev nws lub neej kev pab cuam thiab tswj nws qhov zoo nkauj.
