hlau yeeb nkab tooj liab yeeb nkab profile ua ntawm qhov tshwj xeeb ntawm nws cov kev cai rau tooj liab plating txheej txheem yog txawv los ntawm cov pa steel qhov chaw tooj liab plating yog li yuav ua li cas xaiv haum rau hlau profile ua nrog tooj liab plating txheej txheem yog ib tug tseem ceeb heev lub ntsiab lus feem ntau xaiv electroplating txheej txheem raws li. Thawj cov khoom siv electroplating nws tus kheej yuav tsum tau ua rau plating Qhov ntawd yog, cov khoom ua tiav ua ntej, thiab tom qab ntawd electroplating, xws li thickness, brightness, hardness thiab dispersion muaj peev xwm, thiab lwm yam. pre-txheej ntawm tooj liab plating chaw txheej txheej thiab txheej txheej, thiab cov yam ntxwv ntawm tooj liab pipeline profile ua electroplating yog hais tias cov txheej txheem ntawm hlau thiab electroplating txheej txheem yog tej zaum synchronized uas yog, ib co yog thawj tom qab plating, ib co yog thawj tom qab plating txawm. electroplating ntawm cov khoom xaim, tab sis kuj nyob rau hauv traction ntawm cov kab tshuab xaiv tshuab ntxiv rau qhov sib txawv siv raws li cov xaim thiab txheej txheej, tab sis kuj xav txog cov neeg ua haujlwm electroplating rau cov hlau taug kev ceev traction ntawm qhov ntev ntawm txoj kab thiab lwm yam adaptability Hais txog CO2 roj vuam hlau rau kev saib xyuas, vim ntawm cov tooj liab ntawm cov hlau txuas kom muaj nuj nqis muaj qhov txwv nruj, xws li tooj liab cov ntsiab lus ntawm ib chav tsev ntim yuav tsum nyob rau hauv 0.52 (feem feem ntau) ntawm lub solder, yog ib tug nyias txheej, tshuaj immersion txoj kev piv txwv li hloov tooj liab plating yuav ua tau raws li qhov yuav tsum tau. , tab sis vim hais tias tam sim no domestic siv ib txwm txoj kev los hloov tooj liab plating, lub binding quab yuam Plating xim tsis tau raws li cov khoom yuav tsum tau thiab nyob rau hauv kev xyaum xaiv tus thawj dip rov qab txheej txheem, tooj liab txheej extension thiab thinning nyob rau hauv daim duab, kom ncav cuag cov khoom. yuav tsum tau Txoj kev no feem ntau tam sim no txheej poob tawm Qhia qhov tshwm sim Yog li ntawd, xaiv muaj kev sib raug zoo zog thiabductility ntawm tooj liab plating txheej txheem rau txog roj shielded vuam hlau yog ib qho tseem ceeb heev Nyob rau hauv lub tshiab yuav ua tau kom txhob lo lo ntxhuav cov khoom ib zaug kev vam meej ntawm cov tshuaj tooj liab plating ntawm tooj liab raj tshuab ua ntej, tseem muaj peev xwm tsuas xaiv mus rau thawj axis txoj kab uas hla, rub cov khoom dua tom qab tooj liab. plating tshuab haum cov txheej txheem no yuav tsum yog cyanide tooj liab plating los yog matte acidic tooj liab plating Vim hais tias cov toxicity ntawm cyanide loj dhau lawm, nyob rau hauv metallurgy tooj liab yeeb nkab khoom ua kev lag luam muaj tsawg tus neeg siv Tam sim no, ntau txoj kev nrov yog tseem tshuaj tooj liab leaching thiab Tom qab ntawd thickening tooj liab plating thiab ces kos duab siv rau thickening tooj liab plating rau acid tooj liab plating los yog pyrophosphate tooj liab plating nyob rau hauv ca hlau ua kev lag luam kuj xaiv tshuaj tooj liab plating tsoos tshuaj hloov tooj liab plating yog tooj liab sulfate thiab sulfuric acid txheej txheem Tsuas yog nyob rau hauv ib tug luv luv lub sij hawm yuav muaj ib tug heev nyias txheej hloov, nyob rau hauv lub saum toj no tooj liab plating thickening, binding quab yuam tsis muaj zog yog hais tias nyob rau hauv no tshuaj hloov plating immersion lub sij hawm ntev dhau lawm, tsis tsuas yog yuav tsis ntxiv txheej thickness, tab sis kuj yuav ua rau lub txheej yuav xoob thiab ntxeem tau, hlau matrix kuj yuav tsim corrosion, hlau lub zog zoo heev txo qhov kev txhim kho. txoj kev yog ntxiv additives nrog cov tsos thaiv cov nyhuv nyob rau hauv hloov tooj liab plating tov, thiaj li hais tias cov txheej txheem hloov orderly aspiring additives thiab tej lub teeb nyhuv ntawm qhov yuav tsum tau muaj ib tug tej thickness los yog txawm tuab txheej hlau khoom, xaiv ntawm hloov txheej hauv qab rau ceev faj Tsawg kawg, tsis muaj kev ruaj khov rau kev ua kom tuab tooj liab plating electroplating txheej txheem ua ntej, hais txog lub thickness ntawm tooj liab plating, khoom technology tseem yuav tsum xaiv electrochemical txoj kev precoated precoated nrog cyanide tooj liab plating npib tsib xee plating thiab siab P dua. pyrophosphate tooj liab plating hnyav qhov zoo thiab qhov tsis zoo, hauv kev lag luam hlau kos duab, electroplating npib tsib xee plating li precoated render yog zoo dua Thaum lub thickening tooj liab plating muaj peev xwm xaiv acidic sulfate tooj liab plating Qhov no yog vim hais tias tom qab cov txheej txheem hloov, acid tooj liab plating yuav hloov mus rau qhov yuav tsum tau ntawm high-ceev electroplating tam sim no ceev yuav ncav cuag 30 ~ 50A / dm2, yog li ntawd. tias cov tsub zuj zuj zuj zus tau zoo heev los ntawm qhov sib piv, cyanide tooj liab plating vim hais tias ntawm ib puag ncig muaj kuab paug teeb meem yuav tsum tsis txhob xaiv, thiab pyrophosphate tooj liab plating vim complex muaj pes tsawg leeg, tsis tsuas yog tus nqi siab, thiab tsis haum rau kev ua hauj lwm nyob rau hauv loj tam sim no Qhov kev ntsuam xyuas qhia tau hais tias nyob rau hauv lub complex. high-speed electroplating ntawm acid tooj liab plating, thaum qhov ceev tam sim no nce, lub deposition ceev ntawm txheej kuj nce nyob rau tib lub sij hawm.
