Electroplating tooj liab hloov txoj kev rau hluav taws xob cua sov raj

5. talcum hmoov txoj kev

Muab cov qauv hlau vertically tso rau hauv dej nrog talcum hmoov sprinkled rau saum npoo, thiab ces nqa nws vertically. Nws tuaj yeem pom tias qhov chaw huv si yuav sib npaug nrog cov hmoov talcum, thaum thaj chaw nrog cov roj stains yuav tsis muaj talcum hmoov.

6. Txoj kev hloov tooj liab

Rau cov hlau dub, muab tso rau hauv 63g / LCuSO4 · H2O thiab 17g / LH2SO4, cia nws sawv ntsug li 10 vib nas this, tshem tawm, do hauv dej distilled rau 15 vib nas this, yaug nrog lub raj mis ntxuav, thiab qhuav nws. Ntawm cov hlau huv huv, cov xim liab Cu yog tsim los ntawm cov tshuaj tiv thaiv ntawm Fe ntxiv rau Cu2 ntxiv → Cu ntxiv Fe2 ntxiv, thaum lub paj liab hloov txheej tsis pom ntawm oily nto.

7. Txoj kev tswb tswb

Txoj kev no yog ib txoj kev tshawb nrhiav tshwj xeeb rau tooj liab thiab nws cov alloys. Thaum tooj liab thiab alloys raus rau hauv ib qho 0.025mol/L sodium polysulfide tov thiab sab laug los sawv ntsug rau ib lub sij hawm, tus qauv tooj liab yuav dheev tig dub, uas yog hu ua lub tswb tswb txoj kev. Qhov kev ntxuav ntawm tooj liab, lub sij hawm luv dua nws yuav siv sij hawm tig dub.

8. Lwm txoj kev

Ntxiv rau cov txheej txheem hais saum toj no, qee cov ntaub ntawv kuj pom zoo rau txoj kev potassium ferrocyanide, fluorescence method, dye method, radiation tracing method, combustion method, combustion method, etc.

Ntxiv mus, niaj hnub no, ib txwm siv technology teb tau monopolized los ntawm txawv teb chaws steel giants, txoj kev loj hlob thiab kev tshawb fawb ntawm lub tshuab nqus tsev deposition tshuab rau sawb steel muab ib tug zoo lub sij hawm rau peb lub teb chaws "tsim kom muaj kev ywj pheej kev txawj ntse txoj cai thiab tshem tawm ntawm qhov teeb meem ntawm khiav tom qab. lwm tus rau lub sijhawm ntev. " Cov cuab yeej siv thiab kev tswj cov txheej txheem yog qhov nyuaj, nrog rau kev nqis peev loj, tab sis qhov kev ua tau zoo yog siab thiab nws yog ib qho yooj yim kom ua tiav cov khoom loj, ua tiav lub tshuab nqus tsev nruam ntau lawm los ntawm cov khoom siv raw strip coils kom tiav coated steel strip coils.
