Daim iav kev tsim

- Apr 12, 2019-

Qhov nplaim ntawm lub iav kev sib txuam cov duab pom zoo yog ua los ntawm electroless silver plating thiab nqus evaporation, thiab feem ntau ib qho yog electroless silver plating. Nyob rau hauv txoj kev no, cov roj nitrate yog yaj, dej kua ammonia thiab kua sodium hydroxide tov tau ntxiv thiab ua rau hauv cov nyiaj hydroxide ammonia ob lub ntsev kom npaj tau ib cov nyiaj plating. Inverted qab zib los yog formaldehyde, sodium potassium tartrate kua los ua kev daws teeb meem. Cov iav yog txiav, edging (los yog hauv av thiab polished yog tias tsim nyog), ntxuav rau ntawm qhov chaw, rhiab heev nrog cov stannous chloride tov, ces ntxuav, ces tov nrog cov ntshav plating kua thiab txo cov tshuaj kom sai li sai tau infuse saum npoo, daim iav Ntxuav tom qab tsim, ces tooj liab thiab xim. Lub tshuab nqus tsev yog ua kom ntxuav lub khob thiab muab tso rau hauv lub vapor deposition apparatus nrog lub tshuab nqus tsev ntawm 0.1 mus rau 10-4 Pa, thiab ua kom lub siab xaim tungsten xaim, thiab kub siab yog generated rau sublimate lub aluminium alloy nyob rau hauv lub kauv mus rau lub xeev loj, thiab tso nyiaj rau ntawm lub khob rau daim iav nto. . Siv ib qho hluav taws xob hauv tshuab hluav taws xob los siv tungsten cua sov. Lub tshuab nqus tsev no kuj tuaj yeem tsim cov pa hlau tawm hauv qhov tsom iav
