1. nto hardness
Deg hardness yog ib qho tseem ceeb kom paub qhov txawv ntawm qhov zoo ntawm chrome bar. Vim hais tias lub hardness ntawm cov khoom tsis yog raws li tus qauv, nws yuav ncaj qha shorten lub neej kev pab cuam ntawm cov khoom. Yog li, yog tias koj xav xaiv ib qho zoo chrome bar, koj yuav tsum xyuas nws cov hardness saum npoo.
2. nto roughness
Qhov saum npoo roughness ntawm chrome bar tsis zoo, uas yuav tsis tsuas cuam tshuam rau lub neej kev pab cuam ntawm cov khoom. Hauv qhov xwm txheej hnyav, nws tseem yuav cuam tshuam rau qhov zoo ntawm plating, ua rau ntxov ntxov flaking lossis xeb ntawm cov txheej plating. Cov chaw tsim khoom chrome bar yuav ua rau cov khoom poob nws qhov chaw. Cov nyhuv tiv thaiv. Yog li ntawd, qhov nto roughness kuj yog ib qho ntawm qhov txawv ntawm chrome bar. Feem ntau, qhov zoo ntawm qhov roughness ntawm chrome bar yuav tsum nyob nruab nrab ntawm Ra {{0}}.2 thiab 0.4.
3. nto corrosion xeem
Vim tias cov chrome bar tsuas muaj kev tiv thaiv corrosion, nws tuaj yeem siv rau hauv qhov chaw uas oxidation yooj yim (xws li dej, tshuaj, chav dej, dej hiav txwv, thiab lwm yam) kom ntseeg tau tias nws cov kev ua haujlwm siab. Yog li ntawd, feem ntau zoo chrome bar yuav tsum dhau qhov kev ntsuam xyuas corrosion saum npoo, thiab qhov kev ntsuam xyuas feem ntau mus txog qhov ntsuas ntsev ntsev rau 72 teev kom ncav cuag qib 9.
