Txhua qhov kev hloov kho cov khoom zoo li tib neeg cov pleev. Qhov saum npoo yuav tsum tau coated nrog ob peb txheej ntawm cov ntsiab lus kom ua tiav cov txheej txheem kho kom zoo nkauj. Lub thickness ntawm txheej yog qhia nyob rau hauv microns. Feem ntau, txoj kab uas hla ntawm cov plaub hau yog xya caum los yog yim caum microns, thiab cov hlau txheej yog ob peb txhiab ntawm nws. Cov khoom yog ua los ntawm kev sib xyaw ntawm ntau yam hlau thiab yog plated nrog ob peb txheej ntawm cov hlau sib txawv kom tiav cov pleev. txheej txheem. Kab lus no luv luv qhia txog kev paub txog electroplating thiab xim plating. Cov ntsiab lus yog siv los ntawm cov phooj ywg uas yuav thiab muab cov khoom ntim khoom zoo:
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 yam hlau. Nws yog cov 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 Hlau oxidation (xws li xeb), txhim kho hnav tsis kam, conductivity, reflectivity, corrosion kuj (coated hlau yog feem ntau corrosion-resistant hlau. ) thiab txhim kho qhov tsos.
Txoj Cai
Electroplating yuav tsum muaj hluav taws xob tsawg, siab tam sim no uas muab lub zog rau lub tank electroplating thiab cov khoom siv electrolytic uas muaj cov tshuaj plating, cov khoom yuav tsum tau plated (cathode) thiab anode. Cov txheej txheem electroplating yog txheej txheem uas cov hlau ions hauv cov txheej txheem plating raug txo rau cov hlau atoms los ntawm cov tshuaj tiv thaiv electrode nyob rau hauv qhov kev txiav txim ntawm sab nraud hluav taws xob teb, thiab hlau deposition yog ua nyob rau hauv lub cathode.
Cov ntaub ntawv siv tau
Feem ntau ntawm cov coatings yog ib leeg hlau los yog alloys, xws li titanium, palladium, zinc, cadmium, kub los yog tooj dag, bronze, thiab lwm yam.; tseem muaj cov txheej txheem dispersion, xws li nickel-silicon carbide, nickel-fluorinated graphite, thiab lwm yam.; thiab cladding txheej, xws li ntawm steel Copper-nickel-chromium txheej ntawm steel, silver-indium txheej ntawm hlau, thiab lwm yam. Ntxiv nrog rau cov hlau-raws li cam khwb cia hlau, hlau thiab stainless hlau, cov ntaub ntawv hauv paus rau electroplating kuj muaj xws li cov hlau tsis muaj hlau. hlau, los yog ABS yas, polypropylene, polysulfone thiab phenolic plastics. Txawm li cas los xij, cov yas yuav tsum tau ua kom muaj kev tshwj xeeb thiab kev kho mob ua ntej electroplating.
Plating xim
1) Precious hlau plating: xws li platinum, kub, palladium, nyiaj;
2) General hlau plating: xws li imitation platinum, dub phom, npib tsib xee-dawb tin cobalt, bronze thaum ub, tooj liab liab, ancient silver, ancient tin, thiab lwm yam.
Raws li qhov nyuaj ntawm cov txheej txheem
1) Plating xim: platinum, kub, palladium, nyiaj, imitation platinum, dub phom, npib tsib xee-dawb tin cobalt, pearl npib tsib xee, xim dub plating;
2) Tshwj xeeb plating: antique plating (xws li oiled patina, dyed patina, xov-xov patina), ob-xim, sandblasting plating, txhuam kab plating, thiab lwm yam.
1 platinum
Nws yog ib qho khoom kim heev thiab tsis tshua muaj hlau. Cov xim yog silvery dawb. Nws muaj cov khoom ruaj khov, zoo hnav tsis kam, siab hardness thiab ntev xim tuav lub sijhawm. Nws yog ib qho zoo tshaj plaws electroplating nto xim. Lub thickness yog siab dua 0.03 microns, thiab palladium feem ntau yog siv los ua cov txheej hauv qab kom muaj kev sib koom ua ke zoo, thiab lub foob tuaj yeem khaws cia rau ntau tshaj 5 xyoos.
2 imitation platinum
Cov hlau electroplating yog tooj liab-tin alloy (Cu / Zn), thiab imitation platinum kuj hu ua dawb tooj liab-tin. Cov xim yog ze heev rau dawb kub thiab me ntsis yellower dua dawb kub. Cov khoom yog mos thiab cus ciav, thiab txheej txheej yog yooj yim los ploj. Yog tias kaw, nws tuaj yeem tso tseg rau ib nrab xyoo.
3 kub
Kub (Au) yog hlau muaj nuj nqis. Kev kho kom zoo nkauj plating. Qhov sib txawv ntawm cov khoom xyaw tuaj yeem muaj xim sib txawv: 24K, 18K, 14K. Thiab nyob rau hauv qhov kev txiav txim los ntawm daj mus rau ntsuab, yuav muaj ib co txawv xim ntawm txawv thicknesses. Nws muaj cov khoom ruaj khov thiab nws cov hardness feem ntau yog 1/4-1/6 ntawm platinum. Nws hnav tsis kam yog qhov nruab nrab. Yog li ntawd, nws cov xim txee lub neej yog qhov nruab nrab. Rose kub yog ua los ntawm kub-tooj liab alloy. Raws li kev faib ua feem, xim yog nruab nrab ntawm golden daj thiab liab. Piv nrog rau lwm cov kub, nws muaj zog dua, nyuaj rau kev tswj cov xim, thiab feem ntau muaj xim sib txawv. Lub sijhawm khaws xim xim kuj tsis zoo li lwm yam xim kub thiab nws hloov xim yooj yim.
4 nyiaj
Silver (Ag) yog cov hlau dawb uas muaj zog heev. Nyiaj tau yooj yim hloov xim thaum raug sulfides thiab chlorides hauv huab cua. Nyiaj plating feem ntau siv electrolytic tiv thaiv thiab electrophoresis tiv thaiv kom lub plating lub neej. Ntawm lawv, kev pab cuam lub neej ntawm electrophoresis tiv thaiv yog ntev dua li ntawm electrolysis, tab sis nws yog me ntsis yellowish, glossy khoom yuav muaj ib co me me pinholes, thiab tus nqi kuj yuav nce. Electrophoresis yog tsim los ntawm 150 ° C, thiab cov khoom tiv thaiv los ntawm nws tsis yooj yim rau rework thiab feem ntau muab pov tseg. Silver electrophoresis tuaj yeem khaws cia rau ntau tshaj 1 xyoos yam tsis muaj xim.
5 rwg dub
Cov khoom siv hlau nickel / zinc alloy Ni / Zn), tseem hu ua phom dub lossis npib tsib xee dub. Cov xim plating yog dub, me ntsis grey. Qhov chaw ruaj ntseg yog qhov zoo, tab sis nws yog qhov yooj yim rau xim ntawm qib qis. Cov xim plating no nws tus kheej muaj npib tsib xee thiab tsis tuaj yeem siv rau kev plating tsis muaj npib tsib xee. Cov xim plating tsis yooj yim rau rework thiab hloov kho.
6 npib
Nickel (Ni) yog grey-dawb thiab yog cov hlau uas zoo heev ntom thiab hardness. Nws feem ntau yog siv los ua txheej txheej sealing rau electroplating los txhim kho lub neej kev pab cuam ntawm electroplating. Nws muaj peev xwm ua kom huv si zoo hauv qhov chaw thiab tuaj yeem tiv thaiv corrosion los ntawm huab cua. Nickel yog ib qho nyuaj thiab nkig, yog li nws tsis haum rau cov khoom uas yuav tsum tau deformation thaum electroplating. Thaum cov khoom nickel-plated yog deformed, lub txheej yuav tev tawm. Nickel tuaj yeem ua rau tawv nqaij ua xua rau qee tus neeg.
7 Nickel-dawb tin-cobalt plating
Cov khoom siv yog tin-cobalt alloy (Sn / Co). Cov xim yog xim dub, ze rau rab phom dub (me ntsis greyer dua li rab phom dub), thiab nws yog npib tsib xee dub plating. Qhov saum npoo yog qhov ruaj khov, thiab qib qis ntawm electroplating yog xim xim. Cov xim plating tsis yooj yim rau rework thiab hloov kho.
8 pearl npib
Nws cov khoom yog npib tsib xee, tseem hu ua xuab zeb nickel. Feem ntau siv los ua cov txheej txheem ua ntej-plated hauv qab ntawm pos huab xim txheej txheem. Grey nyob rau hauv cov xim, tsis-glossy daim iav nto, nrog ib tug mos mos-zoo li tsos, zoo li satin. Qib ntawm atomization tsis ruaj khov. Yog tias tsis muaj kev tiv thaiv tshwj xeeb, vim muaj kev cuam tshuam ntawm cov khoom siv xuab zeb, tej zaum yuav muaj kev puas tsuaj rau ntawm daim tawv nqaij.
9 oq xim
Nws yog raws li pearl npib tsib xee ntxiv rau xim nto. Nws muaj cov nyhuv fogging thiab yog matte. Nws txoj kev electroplating yog pre-plated pearl npib tsib xee. Vim tias cov nyhuv atomization ntawm pearl npib tsib xee yog qhov nyuaj rau kev tswj, cov xim ntawm lub ntsej muag tsis sib xws thiab muaj xim sib txawv. Cov xim plating no tsis tuaj yeem siv nrog npib tsib xee plating lossis nrog pob zeb tom qab plating. Cov xim plating no yooj yim rau oxidize, yog li kev saib xyuas tshwj xeeb yuav tsum tau them rau kev tiv thaiv.
10 txhuam hlau plating
Tom qab tooj liab plating, kab yog txhuam rau ntawm tooj liab, thiab tom qab ntawd cov xim saum npoo yog ntxiv. Muaj kev nkag siab ntawm kab. Nws cov xim zoo nkauj yog qhov zoo ib yam li cov xim plating, tab sis qhov txawv yog tias muaj cov kab ntawm qhov chaw. Txhuam xov hlau tsis tuaj yeem yog npib tsib xee plating. Vim tsis muaj nickel plating, lawv lub neej tsis tuaj yeem lav.
11 sandblasting
Sandblasting kuj yog ib txoj hauv kev ntawm electroplating pos huab xim. Cov tooj liab plating yog sandblasted thiab ces electroplated. Lub matte nto yog xuab zeb, thiab tib xim matte yog pom tseeb dua li cov xuab zeb. Zoo li txhuam plating, npib tsib xee plating tsis tuaj yeem ua tiav.
