Nickel ua npuas ncauj txhim kho cov txheej txheem ntau lawm
Mar 16, 2022
Nyob rau hauv cov txheej txheem ntau lawm, cov nyhuv ntawm cov khoom siv ntau tshaj plaws thiab cov khoom siv ntau lawm tsis zoo tagnrho; Nrog rau kev tshawb nrhiav tas li ntawm cov txheej txheem tsim cov nickel ua npuas ncauj, ib qho kev txhim kho ntau lawm rau kev tsim cov khoom siv no kuj tau txais.
Nyob rau hauv cov txheej txheem ntau lawm, polyurethane daim txhuam cev yog thawj conductive. Tom qab ua tiav cov kauj ruam saum toj no, cov txheej txheem ntawm electrodeposition thiab sintering yog nqa tawm. Txawm li cas los xij, nyob rau hauv cov txheej txheem sintering, cov electrodeposited polyurethane ua npuas ncauj yog ncaj qha pyrolyzed thiab sintered nyob rau hauv ib tug txo qhov chaw. Kev txo cov cua siv hauv cov txheej txheem sintering feem ntau yog siv ammonia roj decomposition. Cov hlau tsim los ntawm cov txheej txheem txhim kho no zoo heev txhim kho qhov zoo ntawm cov hlau ua piv rau cov txheej txheem ntau lawm. Nws tuaj yeem daws qhov tsis txaus ntawm kev tawg yooj yim, deformation thiab arching ntawm cov hlau ua npuas dej ua los ntawm cov cuab yeej siv zoo tib yam, thiab tib lub sijhawm, nws muaj cov txiaj ntsig siab heev tom qab tsim khoom, uas txo cov kev siv zog hauv cov txheej txheem ntau lawm.
