Txhua qhov kev hloov kho khoom zoo li tib neeg lub pleev. Qhov saum npoo yuav tsum tau coated nrog ntau txheej ntawm cov ntsiab lus kom ua tiav cov txheej txheem kho kom zoo nkauj ntawm qhov chaw. Lub thickness ntawm cov txheej yog qhia hauv microns. Feem ntau, lub cheeb ntawm cov plaub hau yog xya caum lossis 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 ntau txheej ntawm ntau yam hlau kom ua tiav cov txheej txheem pleev. Tsab xov xwm no luv luv qhia txog kev paub txog electroplating thiab xim plating. Cov ntsiab lus yog rau kev siv los ntawm cov phooj ywg uas yuav thiab muab cov khoom ntim khoom zoo:
Electroplating yog ib qho txheej txheem uas siv lub hauv paus ntsiab lus ntawm electrolysis los muab ib txheej nyias nyias ntawm lwm cov hlau lossis cov khoom sib xyaw rau ntawm qhov chaw ntawm qee cov hlau. Nws yog ib qho txheej txheem uas siv electrolysis los txuas ib zaj duab xis hlau rau ntawm qhov chaw ntawm cov hlau lossis lwm yam khoom siv los tiv thaiv kev oxidation ntawm cov hlau (xws li xeb), txhim kho kev hnav tsis kam, kev coj ua hluav taws xob, kev cuam tshuam, kev tiv thaiv corrosion (cov hlau coated feem ntau yog cov hlau tiv thaiv corrosion) thiab txhim kho qhov zoo nkauj.
Lub Ntsiab Cai
Kev siv hluav taws xob (electroplating) xav tau lub zog hluav taws xob qis, tam sim no siab uas muab hluav taws xob rau lub tank electroplating thiab lub cuab yeej electrolytic uas muaj cov tshuaj plating, cov khoom yuav tsum tau plated (cathode) thiab anode. Cov txheej txheem electroplating yog ib qho txheej txheem uas cov hlau ions hauv cov tshuaj plating raug txo kom ua cov hlau atoms los ntawm cov tshuaj electrode nyob rau hauv qhov kev ua ntawm lub zog hluav taws xob sab nraud, thiab cov hlau deposition raug ua rau ntawm cathode.
Cov ntaub ntawv siv tau
Feem ntau ntawm cov txheej txheej yog cov hlau ib leeg lossis cov hlau sib xyaw, xws li titanium, palladium, zinc, cadmium, kub lossis tooj dag, tooj liab, thiab lwm yam; kuj tseem muaj cov txheej sib cais, xws li nickel-silicon carbide, nickel-fluorinated graphite, thiab lwm yam; thiab cov txheej cladding, xws li ntawm cov hlau Tooj liab-nickel-chromium txheej ntawm cov hlau, nyiaj-indium txheej ntawm cov hlau, thiab lwm yam. Ntxiv rau cov hlau cam khwb cia, hlau thiab stainless hlau, cov ntaub ntawv tseem ceeb rau electroplating kuj suav nrog cov hlau tsis yog ferrous, lossis ABS yas, polypropylene, polysulfone thiab phenolic yas. Txawm li cas los xij, cov yas yuav tsum tau ua kom muaj kev ua haujlwm tshwj xeeb thiab kev kho mob ua ntej electroplating.
Xim plating
1) Cov hlau muaj nqis plating: xws li platinum, kub, palladium, nyiaj;
2) Cov hlau plating dav dav: xws li platinum cuav, phom dub, nickel-free tin cobalt, tooj liab qub, tooj liab liab qub, nyiaj qub, tin qub, thiab lwm yam.
Raws li qhov nyuaj ntawm cov txheej txheem
1) Cov xim plating dav dav: platinum, kub, palladium, nyiaj, platinum cuav, phom dub, nickel-free tin cobalt, pearl nickel, plating xim dub;
2) Kev plating tshwj xeeb: kev plating qub (suav nrog roj patina, dyed patina, xov-threaded patina), ob-xim, sandblasting plating, txhuam kab plating, thiab lwm yam.
1 platinum
Nws yog ib hom hlau kim thiab tsis tshua muaj. Xim yog xim dawb. Nws muaj cov khoom ruaj khov, tiv taus kev hnav zoo, tawv heev thiab khaws xim ntev. Nws yog ib qho ntawm cov xim electroplating nto zoo tshaj plaws. Lub thickness yog siab tshaj 0.03 microns, thiab palladium feem ntau yog siv ua txheej hauv qab kom muaj kev sib koom ua ke zoo, thiab lub foob tuaj yeem khaws cia rau ntau tshaj 5 xyoos.
2 platinum cuav
Cov hlau electroplating yog tooj liab-tin alloy (Cu/Zn), thiab imitation platinum kuj hu ua dawb tooj liab-tin. Cov xim yog ze rau kub dawb thiab me ntsis daj dua li kub dawb. Cov khoom siv yog mos thiab vivid, thiab cov txheej txheej yog yooj yim ploj mus. Yog tias nws raug kaw, nws tuaj yeem tso rau ib nrab xyoo.
3 kub
Kub (Au) yog ib hom hlau muaj nqis. Feem ntau siv rau kev kho kom zoo nkauj. Cov khoom sib txawv muaj ntau yam xim sib txawv: 24K, 18K, 14K. Thiab raws li qhov kev txiav txim no los ntawm daj mus rau ntsuab, yuav muaj qee qhov sib txawv ntawm cov xim ntawm cov tuab sib txawv. Nws muaj cov khoom ruaj khov thiab nws qhov nyuaj feem ntau yog 1/4-1/6 ntawm platinum. Nws qhov kev tiv thaiv kev hnav yog qhov nruab nrab. Yog li ntawd, nws lub neej txee xim yog qhov nruab nrab. Kub liab yog ua los ntawm kub-tooj liab alloy. Raws li qhov sib txawv, xim yog nyob nruab nrab ntawm daj kub thiab liab. Piv nrog rau lwm cov kub, nws muaj zog dua, nyuaj rau tswj cov xim, thiab feem ntau muaj qhov sib txawv ntawm cov xim. Lub sijhawm khaws xim kuj tsis zoo li lwm cov xim kub thiab nws hloov xim yooj yim.
4 nyiaj
Nyiaj (Ag) yog ib hom hlau dawb uas muaj zog heev. Nyiaj yooj yim hloov xim thaum raug rau sulfides thiab chlorides hauv huab cua. Feem ntau, kev plating nyiaj siv kev tiv thaiv electrolytic thiab kev tiv thaiv electrophoresis kom ntseeg tau tias lub neej plating. Ntawm lawv, lub neej ua haujlwm ntawm kev tiv thaiv electrophoresis ntev dua li ntawm electrolysis, tab sis nws yog xim daj me ntsis, cov khoom ci yuav muaj qee qhov me me, thiab tus nqi kuj tseem yuav nce ntxiv. Electrophoresis yog tsim ntawm 150 ° C, thiab cov khoom tiv thaiv los ntawm nws tsis yooj yim rau kev ua haujlwm dua thiab feem ntau raug pov tseg. Silver electrophoresis tuaj yeem khaws cia rau ntau tshaj 1 xyoos yam tsis muaj kev hloov pauv.
5 rab phom dub
Cov khoom siv hlau nickel/zinc alloy Ni/Zn), tseem hu ua phom dub lossis nickel dub. Cov xim plating yog dub, me ntsis grey. Qhov ruaj khov ntawm qhov chaw zoo, tab sis nws yooj yim rau xim ntawm qib qis. Cov xim plating no nws tus kheej muaj nickel thiab tsis tuaj yeem siv rau plating tsis muaj nickel. Cov xim plating tsis yooj yim rau kev ua haujlwm dua thiab kho dua tshiab.
6 npib tsib xees
Nickel (Ni) yog xim grey-dawb thiab yog ib hom hlau uas muaj qhov ceev thiab tawv zoo heev. Feem ntau nws yog siv los ua ib txheej sealing rau electroplating los txhim kho lub neej ua haujlwm ntawm electroplating. Nws muaj peev xwm ua kom huv si zoo hauv huab cua thiab tuaj yeem tiv taus xeb los ntawm huab cua. Nickel yog qhov nyuaj thiab brittle, yog li nws tsis haum rau cov khoom uas xav tau deformation thaum electroplating. Thaum cov khoom nickel-plated raug deformed, lub txheej yuav tev tawm. Nickel yuav ua rau muaj kev ua xua rau qee tus neeg.
7 Kev plating tin-cobalt uas tsis muaj nickel
Cov khoom siv yog tin-cobalt alloy (Sn/Co). Xim yog dub, ze li ntawm rab phom dub (me ntsis greyer dua li rab phom dub), thiab nws yog ib qho plating dub uas tsis muaj nickel. Qhov saum npoo yog qhov ruaj khov, thiab qib qis ntawm electroplating yog qhov yooj yim rau xim. Cov xim plating tsis yooj yim rau kev ua haujlwm dua thiab kho dua tshiab.
8 lub pob zeb nickel
Nws cov khoom siv yog nickel, tseem hu ua xuab zeb nickel. Feem ntau siv ua txheej hauv qab uas tau plated ua ntej ntawm cov txheej txheem xim pos huab. Xim grey, qhov chaw iav tsis ci ntsa iab, nrog rau qhov zoo li pos huab mos mos, zoo li satin. Qib ntawm atomization tsis ruaj khov. Yog tsis muaj kev tiv thaiv tshwj xeeb, vim yog kev cuam tshuam ntawm cov khoom siv xuab zeb, yuav muaj kev hloov pauv xim thaum kov daim tawv nqaij.
9 xim av
Nws yog raws li pearl nickel los ntxiv xim ntawm qhov chaw. Nws muaj cov nyhuv fogging thiab yog matte. Nws txoj kev electroplating yog pre-plated pearl nickel. Vim tias cov nyhuv atomization ntawm pearl nickel nyuaj rau tswj, xim ntawm qhov chaw tsis sib xws thiab yooj yim sib txawv xim. Cov xim plating no tsis tuaj yeem siv nrog nickel-free plating lossis nrog pob zeb tom qab plating. Cov xim plating no yooj yim rau oxidize, yog li yuav tsum tau them sai sai rau kev tiv thaiv.
10 txhuam hlau plating
Tom qab tooj liab plating, cov kab raug txhuam rau ntawm tooj liab, thiab tom qab ntawd xim ntawm qhov chaw raug ntxiv. Muaj kev nkag siab ntawm cov kab. Nws cov xim zoo li zoo ib yam li cov xim plating dav dav, tab sis qhov sib txawv yog tias muaj cov kab ntawm qhov chaw. Cov xov hlau txhuam tsis tuaj yeem yog nickel-free plating. Vim yog nickel-free plating, lawv lub neej tsis tuaj yeem lav.
11 xuab zeb
Kev siv xuab zeb kuj yog ib txoj hauv kev siv electroplating los ua kom cov xim pos huab. Cov tooj liab plating yog sandblasted thiab tom qab ntawd electroplated. Qhov chaw matte yog xuab zeb, thiab tib xim matte pom tseeb dua li cov nyhuv xuab zeb. Ib yam li txhuam plating, nickel-free plating tsis tuaj yeem ua tiav.
