Txoj kev npaj thiab lub hauv paus ntsiab lus ntawm pearl npib tsib xee plating ntawm hluav taws xob cua sov raj

Cov txheej txheem rau kev tsim cov npoo ntawm hlaws npib tsib xee suav nrog txoj kev siv tshuab thiab cov txheej txheem electroplating, thiab cov txheej txheem electroplating tuaj yeem muab faib ua cov txheej txheem plating thiab cov txheej txheem emulsifier.

Mechanical txoj kev koom nrog sandblasting los yog txhaj tshuaj peening lub substrate los ua ib tug ntxhib nto, ua raws li los ntawm electroplating. Lub hlaws zoo li satin nto npaj los ntawm txoj kev no muaj txiaj ntsig zoo, tab sis nws muaj qhov tsis zoo xws li cov khoom seem siab, ib puag ncig ua haujlwm hnyav, thiab kev siv zog ua haujlwm siab, thiab tau raug tshem tawm hauv paus.

Txoj kev sib xyaw plating suav nrog ntxiv cov khoom tsis zoo rau cov txheej txheem plating, thiab nyob rau hauv qhov muaj zog nplawm, cov khoom sib npaug sib npaug hauv cov tshuaj plating thiab co tso nrog npib tsib xee. Cov khoom yog embedded nyob rau hauv lub txheej los ua ib tug npib tsib xee composite txheej [3]. Txawm li cas los xij, vim qhov tsis txaus siab hlaws zoo li cov nyhuv satin thiab softness ntawm cov txheej txheem sib xyaw, nws kuj tau pib theem tawm.

Txoj kev emulsifier tam sim no yog txoj hauv kev zoo tshaj plaws rau kev npaj pearl npib tsib xee coatings thiab tseem yog cov kev tshawb fawb nquag tshaj plaws. Cov organic surfactant ntxiv rau cov tshuaj plating tuaj yeem tsim cov emulsion hauv cov tshuaj plating nyob rau hauv cov txheej txheem tsim nyog, ua rau cov tee me me sib npaug sib npaug hauv cov tshuaj plating. Nyob rau hauv qhov kev txiav txim ntawm ib qho hluav taws xob teb, zoo them me me tee txav mus rau cathode thiab adsorb ntawm lub cathode. Qhov chaw adsorption yog tiv thaiv los ntawm cov tee dej thiab tsis tuaj yeem tso cov hlau, ua kom muaj kab noj hniav hauv cheeb tsam ntawd. Cov txheej txheem adsorption thiab desorption ntawm cov kua mis ntawm lub cathode nto tsis tu ncua, thiab cov electrodeposition ntawm hlau ntawm electrode nto kuj alternates. Yog li ntawd, suav tsis txheeb overlapping ncig kab noj hniav yog tsim nyob rau saum npoo ntawm txheej, thiab cov teebmeem sib txawv ntawm pearlescent txheej tuaj yeem tau txais raws li lawv txoj kab nruab nrab.
