Tsis ntev los no, peb lub Hoobkas tab tom tsim ib pawg ntawm cov hlau tsis xebcov rooj vag dej ntws, uas yog ib hom tshiab ntawm phab ntsa txuas rooj vag tsim los ntawm peb lub Hoobkas, siv tsib txoj kev siv tshuab khoov, me me deformation thiab muaj zog sealing. Tom qablub qhov dej ntawm phab ntsaThaum lub valve vuam, yuav muaj cov tshuaj tiv thaiv dub, cuam tshuam rau qhov tsos, feem ntau yog vim muaj qhov kub siab thaum lub sijhawm vuam, yog li cov hlau ntawm qhov chaw ntawm lub valve oxidizes, tsim cov zaj duab xis dub oxide.

Cov hauv qab no piav qhia txog txoj kev pickling los daws qhov teeb meem blackening:

Lub Hoobkas Jinbin siv txoj kev ntxuav electrolytic pickling, siv electrolytic kev ua thiab tshuaj lom neeg corrosion ntawm acid kom tshem tawm cov zaj duab xis dub oxide ntawm qhov chaw valve. Hauv cov txheej txheem electrolytic, lub valve ua haujlwm ua lub anode, thiab cov zaj duab xis oxide ntawm qhov chaw hlau yog ionized nyob rau hauv qhov kev ua ntawm tam sim no tom qab tau energized, tsim cov hlau ions soluble hauv cov kua qaub, yog li ua kom nrawm tshem tawm ntawm cov zaj duab xis oxide. Tib lub sijhawm, cov hydrogen ions hauv cov kua qaub react chemically nrog cov hlau oxides kom yaj lawv thiab ua tiav lub hom phiaj ntawm kev ntxuav qhov chaw valve.

Cov txheej txheem pickling:

1. Kev kho ua ntej ntawm qhov chaw: Ua ntej pickling, nws yog qhov tsim nyog los ua qhov kev kho ua ntej ntawm qhov chaw ntawm lub valve ua ntej, xws li siv cov txheej txheem kho tshuab kom tshem tawm cov roj, xeb, vuam slag thiab lwm yam tsis huv ntawm qhov chaw kom ntseeg tau tias cov kua qaub tuaj yeem tiv tauj tag nrho cov yeeb yaj kiab oxide thiab txhim kho cov nyhuv pickling.

Nruab thiab dai lub valve kom raug rau ntawm qhov chaw anode ntawm lub electrolytic pickling device kom ntseeg tau tias qhov kev sib cuag ntawm lub valve thiab lub electrode zoo thiab tam sim no tuaj yeem faib sib npaug ntawm qhov chaw ntawm lub valve.

2. Npaj cov kua qaub pickling: Xaiv cov mis acid thiab concentration raws li cov khoom siv thiab qib oxidation ntawm lub valve. Cov acids feem ntau yog sulfuric acid, nitric acid, hydrochloric acid, thiab lwm yam, lossis sib xyaw ntawm lawv. Piv txwv li, rau cov hlau tsis xeb, feem ntau siv cov nitric acid thiab hydrofluoric acid sib xyaw. Thaum teeb tsa cov acid, nws yog qhov tsim nyog ua raws li cov txheej txheem ua haujlwm, them sai sai rau qhov concentration ntawm cov acid, qhov kub thiab qhov ntau ntawm cov additives thiab lwm yam.

3. Electrolytic pickling: Ncuav cov kua qaub uas tau teeb tsa rau hauv lub electrolytic cell, tig rau lub zog hluav taws xob electrolytic, thiab tswj qhov ceev tam sim no, lub sijhawm electrolytic thiab qhov kub ntawm cov kua qaub thiab lwm yam kev ntsuas. Feem ntau hais lus, qhov ceev tam sim no ntau dua thiab lub sijhawm electrolytic ntev dua, qhov zoo dua qhov kev tshem tawm ntawm cov yeeb yaj kiab oxide, tab sis tib lub sijhawm, yuav tsum tau ceev faj kom tsis txhob muaj pickling ntau dhau ua rau muaj kev xeb ntau dhau ntawm cov hlau ntawm lub valve. Qhov kub ntawm cov kua qaub feem ntau raug tswj hwm hauv qee qhov ntau, qhov kub siab dhau yuav ua rau cov kua qaub volatilization thiab decomposition sai dua, cuam tshuam rau cov nyhuv pickling, thiab qhov kub qis dhau yuav ua rau qhov kev cuam tshuam qeeb dhau.

4. Ntxuav dej: Tom qab electrolytic pickling tiav lawm, tshem lub valve ntawm cov kua qaub thiab sai sai muab tso rau hauv dej huv ntws rau kev ntxuav kom tshem tawm cov kua qaub seem thiab cov khoom ua rau ntawm qhov chaw ntawm lub valve. Lub sijhawm ntxuav thiab qhov ceev ntawm dej ntws yuav tsum txaus kom ntseeg tau tias pH ntawm qhov chaw ntawm lub valve ncav cuag qhov nruab nrab thiab tiv thaiv cov kua qaub seem los ntawm kev ua rau xeb thib ob rau lub valve.

5. Kev kho tom qab: Lub valve tom qab ntxuav tuaj yeem kho ntxiv raws li qhov xav tau, xws li kev kho passivation, kev kho tiv thaiv xeb, thiab lwm yam, los txhim kho kev tiv thaiv corrosion thiab lub neej ua haujlwm ntawm lub valve. 

Jinbin Valve ua lub chaw tsim khoom penstock, tsim txhua yam ntawm cov khoom siv hlau, lub qhov rooj hlau stainless hlau penstock, lub qhov rooj loj loj, lub qhov rooj npauj npaim, thiab lwm yam, yog tias koj muaj cov kev xav tau cuam tshuam, thov tawm lus hauv qab no lossis email tiv tauj peb, koj yuav tau txais lus teb hauv 24 teev, tos ntsoov yuav ua haujlwm nrog koj!
