Hom thiab cov khoom ntawm acid pickling kua rau hluav taws xob cua sov raj electroplating
Muaj ntau ntau txoj kev siv pickling:
Hydrochloric acid hom: Nrog rau cov yam ntxwv ntawm hydrochloric acid, nws muaj zog xeb tshem tawm muaj peev xwm thiab ceev ceev. Nws yog feem ntau kho nyob rau hauv chav tsev kub thiab muaj tus nqi nruab nrab, tab sis nws yog ib qho yooj yim rau volatilize, muaj ib tug loj acid pos huab, thiab muaj me ntsis kev ua hauj lwm tsis zoo. Niaj hnub no, tib neeg tau siv zog ntau rau hauv cov khoom siv ntxiv, ua rau muaj ntau yam kev txhim kho hauv cov khoom lag luam, txhim kho kev ua haujlwm tau zoo, thiab kev pab cuam lub neej luv dua piv rau hom sulfuric acid.
Sulfuric acid hom: Nrog rau cov yam ntxwv ntawm sulfuric acid, nws yog qhov ruaj khov, thiab cov xeb tshem tawm ceev qeeb qeeb dua li hom hydrochloric acid. Nws feem ntau xav tau kev kho mob diffusion, muaj lub neej ua haujlwm ntev, thiab pheej yig.
Hom sib xyaw (ntsev ntxiv rau sulfuric acid): Qhov zoo thiab qhov tsis zoo ntawm hom hydrochloric acid thiab sulfuric acid hom yog ua tiav.
Qhov "ob leeg hauv ib qho" yog hais txog cov kua qaub ntxuav siv rau degreasing thiab xeb tshem tawm. Qhov zoo tshaj plaws thiab zoo tshaj plaws yog hom hydrochloric acid, tus cwj pwm los ntawm cov roj ceev thiab xeb tshem tawm ceev, kev kho mob hauv chav sov, thiab tus nqi nruab nrab. Yog tias cov neeg siv muaj cov txheej txheem kev npaj rau lawv tus kheej, nws kuj yog ib qho ntawm ntau yam zoo dua.
"peb nyob rau hauv ib" yog hais txog cov kua qaub ntxuav uas ib txhij tshem tawm cov roj, xeb, thiab phosphating. Cov tshuaj ntxuav no tsis haum rau cov txheej txheej electrophoretic vim yog cov laj thawj hauv qab no: 1. Cov tshuaj ntxhua khaub ncaws siv phosphoric acid, uas yog kim heev. 2-phosphoric acid yog cov kua qaub uas tsis muaj zog uas muaj peev xwm tshem tawm xeb, ua rau nws nyuaj los xyuas kom cov xeb tshem tawm zoo. 3. "phosphating zaj duab xis" tau txais tom qab kev kho mob dissolves sai sai hauv dej, uas tsis tsuas yog tsis tuaj yeem tiv thaiv xeb, tab sis kuj pollutes electrophoresis tank tov nrog nws cov khoom yaj.
Lub "plaub hauv ib" yog hais txog kev ntxuav cov kua qaub uas ib txhij tshem tawm cov roj, xeb, phosphating, thiab passivation. Nws qhov kev ua tau zoo, kev ua haujlwm, thiab qhov zoo thiab qhov tsis zoo yog qhov zoo ib yam li "peb hauv ib qho".
