Txoj kev los ntawm kev tsim Tsom iav
- Mar 01, 2018 -

Muaj ob txoj kev ntawm electrolessess silver plating thiab lub tshuab nqus tsev vacuum rau kev ua haujlwm saum npoo ntawm qhov pom ntawm lub iav pom, cov khoom siv tshuaj uas yog khwv tau siv ntau tshaj plaws.

Cov txheej txheem yog yaj cov dej nitrate hauv dej, ntxiv tshuaj ammonia thiab kua tshuaj sodium hydroxide thiab dilute mus rau hauv cov nyiaj ammonium hydroxide, thiab ua cov nyiaj plating. Los hloov piam thaj los yog formaldehyde, potassium sodium tartrate tov rau kev txo cov kua. Daim iav yog txiav, sib tsoo ntug (thiab tom qab sib tsoo thiab polishing), ntxuav qhov chaw, siv cov tin chloride dilute tov tshuaj kho, thiab tom qab ntawd ntxuav, thiab mam li tov nrog cov xim plating kua thiab txo cov kua kom sai rau ntawm qhov chaw, daim iav tom qab qhov tsim ntawm ntxuav, thiab tom qab ntawd ces yuav ua tau tooj liab thiab txheej xim.

Lub tshuab nqus tsev yog ua kom ntxuav lub khob, muab tso rau hauv 0.1 ~ 10pa nqus cov evaporation ntawm lub cuab yeej, lub kauv tungsten xaim fais fab, ua rau kub siab ntawm txhuas aluminium alloy evaporation rau hauv ib lub gaseous, tso rau hauv iav ntu daim ib daim iav. kuj tseem siv tau siv phom tua hluav taws los hloov cov tungsten hlau cua sov. Lub tshuab nqus tsev evaporation txheej txheem kuj tseem yuav tau cov hlau nplaum ua rau hauv daim iav.
