69. Dab tsi yog cov yam ntxwv ntawm kev tshem tawm cov roj electrolytic piv rau kev tshem tawm cov roj tshuaj?
Teb: Cov muaj pes tsawg leeg ntawm cov tshuaj electrolytic degreasing yog roughly tib yam li cov tshuaj degreasing tshuaj. Qhov ceev ntawm electrochemical tshem tawm roj yog feem ntau siab dua li ntawm cov tshuaj tshem tawm cov roj, uas ua rau ib tug huv si tshem tawm cov roj stains. Lub alkalinity nyob rau hauv cov tshuaj electrochemical tshem tawm cov roj yuav txo tau me ntsis piv rau cov tshuaj tshem tawm roj, raws li saponification tsis yog lub luag hauj lwm rau lub sij hawm no, thiab tsis tas yuav ntxiv emulsifiers. Yog tias siv emulsifiers, lawv yuav tsim ntau cov npuas dej ntab rau ntawm qhov chaw daws teeb meem, yog li tiv thaiv kev khiav tawm ntawm hydrogen thiab oxygen. Thaum muaj kev sib cuag hluav taws xob tsis zoo thiab hluav taws xob tshwm sim, nws yooj yim ua rau muaj kev sib tsoo tawg. Txhawm rau kom ntseeg tau qhov zoo ntawm cov txheej txheem electroplating, electrochemical degreasing feem ntau yog siv ua ntej electroplating cov khoom rau hauv lub tank.
70. Dab tsi yog qhov txawv ntawm cathodic electrolysis thiab anodic electrolysis rau kev tshem tawm roj?
Teb: Electrolytic roj tshem tawm tuaj yeem nqa tawm ntawm ob qho tib si cathode thiab anode, thiab cov yam ntxwv ntawm cathode thiab anode roj tshem tawm txawv. Cov yam ntxwv ntawm kev tshem tawm cov roj cathodic yog: cov roj tso tawm yog cov pa roj hydrogen, nrog cov pa me me, ntau, thiab cov npuas loj, uas ua rau cov roj tshem tawm tau zoo thiab tsis muaj corrosion ntawm qhov chaw; Qhov tsis zoo yog tias hydrogen embrittlement tshwm sim thiab muaj cov tshauv dai. Cov yam ntxwv ntawm cov roj anode tshem tawm yog: tsis muaj hydrogen embrittlement, tsis muaj tshauv residue; Tab sis qhov tsis zoo yog qhov ua haujlwm qis thiab siab corrosiveness rau cov hlau tsis muaj hlau.
