Ua ntej, cia peb nkag siab tias electroplating yog dab tsi
Electroplating yog txheej txheem uas siv lub hauv paus ntsiab lus ntawm electrolysis rau phaj nyias txheej ntawm lwm yam hlau los yog alloys ntawm tej qhov chaw hlau. Nws yog txheej txheem uas siv electrolysis los txuas cov yeeb yaj kiab hlau rau saum npoo ntawm cov hlau lossis lwm yam khoom siv los tiv thaiv cov hlau oxidation (xws li xeb), txhim kho hnav tsis kam, conductivity, reflectivity, corrosion resistance (tooj liab sulfate, thiab lwm yam) thiab txhim khu kev qha. tsos.
Electroplating tau muab faib ua cov txheej txheem tshwj xeeb xws li tooj liab plating, kub plating, nyiaj plating, chromium plating, npib tsib xee plating thiab zinc plating. Hauv kev tsim khoom, zinc plating, npib tsib xee plating thiab chromium plating yog siv dav tshaj plaws. Thiab yuav tsum muaj qee qhov sib txawv ntawm peb qhov no, puas yog?
01-Galvanized
▼
Cov ntsiab lus: Galvanizing yog hais txog kev kho cov txheej txheem saum npoo uas txheej txheej ntawm cov hlau, hlau lossis lwm yam khoom siv nrog txheej zinc rau kev zoo nkauj, tiv thaiv xeb thiab lwm yam haujlwm.
Nta: tus nqi qis, dav dav corrosion kuj, silvery dawb xim.
Daim ntawv thov: screws, circuit breakers, industrial khoom, thiab lwm yam.
02-Nickel plating
▼
Lus Txhais: Ib txoj kev ntawm plating ib txheej ntawm npib tsib xee rau hlau los yog tej yam uas tsis yog hlau los ntawm electrolysis los yog chemical txoj kev hu ua npib tsib xee plating.
Nta: zoo nkauj, tuaj yeem siv rau kev kho kom zoo nkauj, tus nqi siab, txheej txheem me ntsis nyuaj, silvery dawb nrog cov xim daj.
Daim ntawv thov: lub zog txuag teeb tuav, npib, kho vajtse, thiab lwm yam.
03-Chrome plating
▼
Lus Txhais: Chromium yog ib lub ci dawb hlau nrog me ntsis bluish tint. Nws yog ib txoj hauv kev plating txheej ntawm chromium ntawm cov hlau lossis qee yam tsis yog hlau los ntawm electrolysis lossis tshuaj, uas yog hu ua chromium plating.
Nta: Muaj ob hom chromium plating. Thawj qhov yog rau kev kho kom zoo nkauj, nrog lub ntsej muag ci thiab kev sib txhuam zoo. Nws lub peev xwm los tiv thaiv xeb tsis zoo li galvanizing tab sis zoo dua oxidation; Qhov thib ob yog ua kom lub hardness thiab hnav tsis kam ntawm cov hlau qhov chaw. , uas yog lub functionality ntawm ib feem.
Daim Ntawv Thov: Ci ntsa iab qhov chaw ntawm cov khoom siv hauv tsev, cov khoom siv hluav taws xob thiab lwm yam khoom siv, cov cuab yeej, faucets, thiab lwm yam.
Raws li qhov yooj yim tshaj qhov sib txawv ntawm peb hom electroplating
1: "Chromium plating yog tsuas yog los txhim kho qhov tawv tawv, zoo li, thiab tiv thaiv xeb. Chromium plating muaj cov tshuaj zoo ruaj khov thiab tsis muaj kev cuam tshuam rau alkali, sulfide, nitric acid thiab feem ntau cov organic acids, tab sis nws tuaj yeem yaj hauv hydrohalic acid (xws li. Raws li hydrochloric acid) thiab kub sulfuric acid, vim tias chromium tsis hloov xim thiab tuaj yeem tswj nws lub peev xwm cuam tshuam rau lub sijhawm ntev thaum siv, nws zoo dua li nyiaj thiab npib tsib xee, cov txheej txheem feem ntau yog electroplating.
2: Nickel plating feem ntau yog hnav-tiv taus, tiv thaiv corrosion, thiab tiv thaiv xeb. Nws yog feem ntau nyias nyob rau hauv thickness. Cov txheej txheem tau muab faib ua ob pawg: electroplating thiab tshuaj lom neeg.
3: Galvanizing feem ntau yog rau kev zoo nkauj thiab tiv thaiv xeb. Zn yog cov hlau nquag uas tuaj yeem ua rau cov kua qaub, yog li nws muaj qhov tsis zoo corrosion thiab yog qhov pheej yig tshaj ntawm peb.
Qhov sib txawv ntawm tus nqi yog tias chromium plating yog kim tshaj plaws, ua raws li nickel, thiab zinc yog qhov pheej yig tshaj. Ntawm lawv, khib plating, chim plating, thiab lwm yam kuj txawv. Khib plating yog kim, thiab chim plating yog pheej yig.
Cia peb paub qhov txawv ntawm cov xim.
Chrome plating yog ci dawb, npib tsib xee plating yog daj me ntsis, thiab zinc plating yog silvery dawb (qhov tseeb, kuj muaj cov xim zinc, grey zinc, matte chrome, ci chrome, dawb npib tsib xee, dub npib tsib xee, thiab lwm yam. Qhov ntau koj tham. txog nws, qhov ruam ntau koj tsis tuaj yeem qhia lawv sib nrug. clear)
nthuav koj txoj kev paub:
1-Kev tsim hluav taws xob feem ntau yog tshwm sim los ntawm cov dej phwj tuaj thiab cov hlau hnyav hauv cov dej phwj tuaj. Lub xeev tau nruj me ntsis tswj kev nthuav dav ntawm kev lag luam electroplating thiab txo nws txhua xyoo.
2-Cov txheej txheem electroplating tseem ceeb hauv kuv lub tebchaws yog zinc plating, tooj liab plating, npib tsib xee plating thiab chromium plating, ntawm cov zinc plating nyiaj rau 50% thiab tooj liab, chromium thiab npib tsib xee plating account rau 30%.
3-Yog tias lub hom phiaj yog los tiv thaiv xeb, zinc plating lossis cadmium plating tuaj yeem siv tau; yog tias qhov tsom mus tiv thaiv kev hnav thiab tsim kua muag, nickel plating lossis chromium plating yog qhov kev xaiv zoo tshaj.
Electroplating yog ib qho kev paub tob heev
Nws tsis yog ib yam uas tuaj yeem hais meej hauv ib lossis ob kab lus.
Thiab txoj kev plating ntawm txhua yam khoom sib txawv
Electroplating ua ntej kev kho mob, electrolyte formula, tam sim no loj, electroplating lub sij hawm, thiab lwm yam.
Txhua qhov kev nthuav dav yuav ua rau muaj kev hloov pauv hauv plating zoo
Sib nrug los ntawm lwm yam
Tam sim no me dua thiab lub sij hawm plating ntev dua.
Qhov zoo ntawm cov khoom plated nyob rau hauv txoj kev no zoo dua
Nws yog me ntsis zoo li simmering tshaj qis cua sov
Tau kawg, tus nqi kuj nce linearly.
Cia peb saib cov yees duab yuav ua li cas rau plating nws.
