Yuav ua li cas thiaj li yuav electroplating txhim kho kev ua haujlwm ib puag ncig ntawm cov khoom lag luam? Cov txheej txheem twg tuaj yeem txo cov pa phem ib puag ncig?
Electroplating yog qhov kev kho tshuab saum npoo av dav siv hauv kev lag luam tsim. Nws tso nyiaj ib txheej hlau lossis alloy ntawm cov hlau lossis tsis yog {1} Cov khoom lag luam tsis kam txhim kho, coj kev tawm tsam, kev coj ua, thiab tsos. Txawm li cas los xij, cov txheej txheem electroplating feem ntau cuam tshuam nrog cov teeb meem muaj kuab paug muaj kuab paug, xws li cov pa phem rau cov tshuaj phem, thiab siv hluav taws xob. Nrog rau kev paub txog ib puag ncig ib puag ncig thiab nce qib kev lag luam antently xav tau kev cuam tshuam ib puag ncig thiab txo incologological innovation thiab cov txheej txheem ua kom zoo dua. Kab lus no yuav tshawb txog kev ua haujlwm ib puag ncig los ntawm kev txhim kho cov txheej txheem electroplating, thiab qhia cov txheej txheem ntau lawm, thiab ua kom muaj kuab paug ntau zog.
I. Txoj hauv kev los txhim kho kev ua yeeb yam ib puag ncig ntawm cov txheej txheem electroplating
1. Siv cov phooj ywg zoo Electroplating daws teeb meem
Cov tshuaj elotions feem ntau muaj cov tshuaj lom xws li cyanide thiab hexavalent chromium, uas yog kev ua phem rau ib puag ncig thiab kev noj qab haus huv. Siv cov kev daws teeb meem electroplating yog qhov tseem ceeb los txhim kho kev ua haujlwm ib puag ncig ntawm cov txheej txheem electroplating. Piv txwv li:
-} Cyanide {{1 }> Hloov cov txheej cyanide tsoos plating, txo qhov kev tawm tsam ntawm cov tshuaj lom neeg lom zem. Cyanide - Txoj kev hloov pauv dawb tau siv dav hauv electroplating cov hlau xws li tooj liab, zinc, thiab kub.
{{0-}}} pa roj chromium plating daws: Qhov no hloov heXavalent txoj kev hloov pauv, txo cov kuab paug hlau. Truntic Chromium plating tov yog tsawg lom thiab ua kom yooj yim siv dej khib nyiab.
- Txhob - Kev daws teeb meem ywj pheej, kev siv cov hmoov txhuas ua kom muaj kev lag luam zoo li ib puag ncig xws li ROHS.
2. Txhim kho cov txheej txheem electrandating txheej txheem
Los ntawm kev ua kom zoo dua electrandating cov txheej txheem electrandlating cov txheej txheem tsis zoo, kev siv tshuaj lom neeg siv tshuaj thiab dej khib nyiab thiab cov dej khib nyiab tuaj yeem txo. Kev ntsuas tshwj xeeb muaj xws li:
-} Txo qhov ceev tam sim no: kev txiav txim siab tam sim no thiab cov kev ua kom zoo nkauj, thaum txhim kho kev sib txuam ntawm cov txheej txheem.
{-} m} tswj lub sijhawm plating tuaj yeem zam kev ua kom dhau thiab txo cov kua pov tseg thiab cov khoom pov tseg.
-}}} Txhim kho cov khoom siv hluav taws xob: los ntawm kev txhim kho hluav taws xob cov khoom siv thiab cov khoom siv hluav taws xob tau nce ntxiv, kom tsis txhob siv hluav taws xob thiab cov dej tawm.
3. Taw qhia cov cuab yeej ntsuab cov cuab yeej ntsuab
Ntxiv nrog rau cov txheej txheem hluav taws xob ib txwm muaj, lwm cov kev kho kom zoo rau cov thev naus laus zis tuaj yeem qhia tau, xws li:
-} Electroless plating) plating sab nraud uas tsis tas yuav muaj lub zog sab nraud uas tsis xav tau ib lub zog sab nraud thiab tso nyiaj rau ntawm cov nplaim dej. Wastewater kev kho los ntawm electroless plating yog qhov yooj yim me ntsis, thiab txheej yog niaj hnub hnav.
- papor dependation (PVD): PVD): Tshem tawm cov kev xav tau ntawm lub cev, rho tawm cov tshuaj lim dej thiab tshuaj lom neeg.
{{0- kub}- dip plating: kub}}}}} dip plating enlttrate hauv molten hlau los ua txheej. Tus txheej txheem no yooj yim thiab ib puag ncig phooj ywg.
4. Ntxiv dag zog rau kev kho mob thiab cov peev txheej rov qab
Wastewater tsim tawm thaum lub sijhawm tsim hluav taws xob muaj cov hlau hlau hnyav thiab tshuaj lom neeg thiab yuav tsum tau kho nruj ua ntej tawm. Cov kev ntsuas hauv qab no tuaj yeem txhim kho cov kev kho kom muaj kev txuag nyiaj thiab cov peev txheej no:
{{0- Kev Kho Mob Hluav Taws Xob: Ntau hom hluav taws xob raug kho kom zoo dua los txhim kho kev txuag tshuaj kho mob thiab txo cov tshuaj reagents.
- Mem Membrane Kev Sib Txawv Technologies xws li thim osmosis sib cais xws li thim cov hlau ions thiab cov organic paug los ntawm cov dej qias neeg.
-}} ions yog rov qab los ntawm cov txheej txheem xws li cov peev txheej electrolysis thiab ion kev hloov pauv thiab txo cov khoom siv raw thiab txo cov khoom siv raw thiab roj.
5. Txhawb kev ua kom huv
Kev lag luam huv yog ib txoj kev tsim khoom uas txo cov pa phem ntawm qhov chaw. Nws txo cov khoom thiab kev tawm ntawm cov pa phem los ntawm kev txhim kho cov txheej txheem ntau lawm, txhim kho cov cuab yeej, thiab ntxiv dag zog rau kev tswj hwm. Kev ntsuas tshwj xeeb muaj xws li:
{{0 {{}} siv tshuab automated: txhim kho cov khoom siv tswj tau ntau dua thiab cov khoom siv tsis zoo, thiab txo cov dej khib nyiab thiab tso zis tawm.
-} Kev txuag hluav taws xob thiab emission txo qis: Siv cov khoom siv txuag thiab tsev cog khoom roj.
{- Cov kua dej ua haujlwm, cov khoom siv hluav taws xob, thiab cov khoom siv pov tseg kom txo cov khoom qias neeg thiab ib txwm muaj kuab paug.
Ii. Cov txheej txheem uas txo cov pa phem ib puag ncig
1. Cyanide -} ywj pheej electroplating
Cyanide -} ywj pheej electroplating tau yog qhov tseem ceeb ntawm kev lag luam electroplating hauv xyoo tas los no. Thaum ib txwm cyanide electraphplating cov kev daws teeb meem thiab nyuaj rau kev daws teeb meem muaj qhov zoo ntawm kev lom zem tsawg thiab ib puag ncig ua phooj ywg. Piv txwv li, cov txheej txheem xws li cynaide {{} dawb tooj dawb cyanide plating thiab yog dav siv nyob rau hauv lub tsheb, khoom siv hluav taws xob, thiab kev kho vajtse.
2. Trivalent Chromium Electroplating
Truntic Electroplating yog ib puag ncig tus phooj ywg hloov mus rau hexavalent chromium plating. Hexavalent chromium yog lub zog carcinogen, poss cov kev pheej hmoo rau ib puag ncig thiab tib neeg kev noj qab haus huv. Cov kev sib tw sib xws, ntawm qhov tod tes, yog cov tshuaj lom tsawg dua thiab tsim cov txheej ci nrog qhov ua tau zoo sib piv. Truntic Electroplating yog dav siv nyob rau hauv kev dai kom zoo nkauj thiab ua haujlwm chromium plating.
3. Lead -} ywj pheej electroplating
Hmoov txhuas yog ib qho tshuaj phom sij hauv cov khoom siv hluav taws xob, thiab cov taug kev ncig ua si {{tin} Tin} Tin ™Y allroL electroplating cov txheej txheem tuaj yeem tsim cov pa phem. Lead - ywj pheej siv hluav taws xob xws li tin, txo cov kab mob ua si ib puag ncig thiab ua raws li ib puag ncig cov kev cai xws li ROHS.
4. Electroless npib tsib xee plating
Electroless npib tag nrho yog txheej txheej thev naus laus zis uas tsis tas yuav muaj lub zog sab nraud. Nws tso nyiaj npib tsib xee nyob rau ntawm substrate nto los ntawm cov tshuaj lom neeg tshuaj lom neeg. Tus txheej txheem no muaj cov txiaj ntsig xws li txheej tsis zoo xws li kev kho kom yooj yim, nrog rau kev kho kom yooj yim rau ib puag ncig cov pa phem.
5. Lub cev vapor deposition (PVD)
Cov txheej txheem PVD tso ib hlau lossis alloy mus rau hauv substrate saum toj los ntawm lub cev txhais tau tias, tshem tawm cov kev xav tau tshuaj. Qhov no txo cov dej khib nyiab thiab tshuaj ua qias tuaj. PVD yog dav siv nyob rau hauv cov ntawv thov xws li txiav cov cuab yeej, pwm, thiab cov tsho tuab si.
6. Kub - dip plating
Qhov kub -} dip plating cov txheej txheem cuam tshuam nrog immersing lub substrate hauv molten hlau los ua txheej. Nws yog cov txheej txheem yooj yim thiab ib puag ncig zoo. Kub - dip plating yog dav siv rau kev tiv thaiv steel, xws li kub}}} dip aluminizing.
III. Lub ntsiab
Electroplating, raws li kev kho tshuab nto cuam tseem ceeb, txhim kho cov khoom lag luam thaum tseem ntsib kev sib tw ntawm kev ua pa dawb paug. Los ntawm kev npaj ua cov kev nyiam plating, ua kom zoo dua cov txheej txheem kev kho, thiab txhawb kev ua phooj ywg kom zoo thiab ua kom muaj kuab paug ib puag ncig. Tsis tas li ntawd, kev nce qib thiab kev siv ntawm cov txheej txheem phooj ywg zoo xws li} dawb inctroplating, pv} rustinable kev loj hlob ntawm kev lag luam electroplating. Nyob rau yav tom ntej, nrog kev nce qib nruam ntawm cov kev tiv thaiv ib puag ncig cov txheej txheem, kev txhim kho electroplating yuav txuas ntxiv rau hauv ib qho kev coj ua zoo dua thiab muaj txiaj ntsig.
