Chimwe nechimwe chekugadzirisa chigadzirwa chakafanana nekugadzirwa kwevanhu. Iyo yepamusoro inoda kuvezwa nemateru akati wandei emukati kuti ipedze iyo yekushongedza kwepamusoro maitiro. Ukobvu hwekuputira hunoratidzwa mumamicrons. Kazhinji, dhayamita yebvudzi inosvika makumi manomwe kana makumi masere microns, uye iyo simbi yekuputira ishoma zviuru zvishoma zvayo. Chigadzirwa chacho chinogadzirwa nemusanganiswa wesimbi dzakasiyana-siyana uye chakaputirwa nemateru akati wandei emasimbi akasiyana kuti apedze makeup. process. Ichi chinyorwa chinosuma muchidimbu ruzivo rwakakodzera rwe electroplating uye color plating. Izvo zvirimo ndezvekutarisa neshamwari dzinotenga uye dzinopa emhando yepamusoro yekurongedza zvinhu masisitimu:
Electroplating inzira inoshandisa musimboti we electrolysis kupinza chidimbu chitete chemamwe masimbi kana alloys pamusoro pedzimwe simbi. Inzira inoshandisa electrolysis kubatanidza firimu resimbi pamusoro pesimbi kana zvimwe zvinhu kudzivirira Metal oxidation (senge ngura), inovandudza kusapfeka, conductivity, reflectivity, corrosion resistance (simbi dzakaputirwa dzinowanzoita simbi isingadziviriri. ) uye inovandudza chitarisiko.
Principle
Electroplating inoda low-voltage, high-current power supply inopa simba kune electroplating tank uye electrolytic device ine plating solution, zvikamu zvinofanira kuiswa (cathode) uye anode. Iyo electroplating process inzira iyo iyo simbi ions muplating mhinduro inoderedzwa kuita maatomu esimbi kuburikidza ne electrode reactions pasi pechiito chekunze kwemagetsi munda, uye simbi deposition inoitwa pane cathode.
Inoshanda zvinhu
Mazhinji ekuputira isimbi imwe chete kana alloys, senge titanium, palladium, zinc, cadmium, goridhe kana ndarira, ndarira, nezvimwewo; kunewo zvidimbu zvekuparadzira, zvakadai se nickel-silicon carbide, nickel-fluorinated graphite, nezvimwewo; uye cladding layers, senge simbi Mhangura-nickel-chromium layer pasimbi, sirivheri-idium layer pasimbi, etc. Mukuwedzera kune iron-based cast cast iron, simbi uye Stainless simbi, hwaro zvinhu zve electroplating zvinosanganisirawo asiri ferrous. simbi, kana ABS mapurasitiki, polypropylene, polysulfone uye phenolic mapurasitiki. Nekudaro, mapurasitiki anofanirwa kuita yakakosha activation uye sensitization kurapwa isati yaitwa electroplating.
Plating color
1) Kuiswa kwesimbi yakakosha: seplatinamu, goridhe, palladium, sirivha;
2) General metal plating: senge yekutevedzera platinum, pfuti nhema, nickel-isina tin cobalt, yekare bhuronzi, yekare tsvuku mhangura, sirivha yekare, tini yekare, nezvimwe.
Maererano nekuoma kwemaitiro
1) General plating mavara: platinamu, goridhe, palladium, sirivheri, yekutevedzera platinamu, pfuti nhema, nickel-isina tini cobalt, pearl nickel, dema pendi plating;
2) Special plating: antique plating (inosanganisira oiled patina, dyed patina, thread-threaded patina), maviri-mavara, sandblasting plating, brush line plating, nezvimwewo.
1 platinum
Isimbi inodhura uye isingawanzoitiki. Ruvara rwakachena chena. Iine zvinhu zvakagadzikana, zvakanaka kupfeka kusagadzikana, kuoma kwepamusoro uye nguva yakareba yekuchengetedza ruvara. Ndiyo imwe yeakanakisa electroplating pamusoro pemavara. Ukobvu huri pamusoro pe 0.03 microns, uye palladium inowanzo shandiswa seyakadzika pasi kuti ive yakanaka synergistic mhedzisiro, uye chisimbiso chinogona kuchengetwa kweanopfuura makore mashanu.
2 kutevedzera platinum
Iyo electroplating simbi ndeyemhangura-tin alloy (Cu / Zn), uye kutevedzera platinum inonziwo chena mhangura-tin. Ruvara rwacho ruri padyo negoridhe chena uye zvishoma yero pane goridhe jena. Izvo zvinhu zvakapfava uye zvine hupenyu, uye iyo pamusoro peiyo coating iri nyore kupera. Kana yakavharwa, inogona kusara kwehafu yegore.
3 goridhe
Ndarama (Au) isimbi inokosha. Common decoration plating. Zviyero zvakasiyana zvezvigadzirwa zvinouya nemavara akasiyana: 24K, 18K, 14K. Uye mukurongeka uku kubva kune yero kusvika kune yakasvibira, pachava nemisiyano yemuvara pakati pehukobvu hwakasiyana. Iine zvimiro zvakagadzikana uye kuoma kwayo kunowanzo 1/4-1/6 yeplatinamu. Kuramba kwayo kupfeka kuri pakati. Nokudaro, mararamiro esherufu yemavara ayo akaenzana. Rose goridhe rakagadzirwa negoridhe-copper alloy. Maererano nechiyero, ruvara rwuri pakati pegoridhe yero uye tsvuku. Kana ichienzaniswa nemamwe goridhe, ine upenyu, yakaoma kudzora ruvara, uye kazhinji ine misiyano yemavara. Nguva yekuchengetedza ruvara hainawo kunaka semamwe mavara egoridhe uye inoshandura ruvara nyore.
4 sirivheri
Sirivha (Ag) isimbi chena inoita reactive zvakanyanya. Sirivha inoshandura ruvara zviri nyore kana yakafumurwa kune sulfides uye chlorides mumhepo. Sirivha plating inowanzo shandisa electrolytic dziviriro uye electrophoresis kuchengetedzwa kuti ive nechokwadi chehupenyu hweplating. Pakati pavo, hupenyu hwesevhisi yekudzivirira kwe electrophoresis hwakareba kupfuura iyo ye electrolysis, asi iine yero, zvigadzirwa zvinopenya zvichange zvine mapinho madiki, uye mutengo uchawedzerawo. Electrophoresis inoumbwa pa 150 ° C, uye zvigadzirwa zvakadzivirirwa nazvo hazvisi nyore kugadzirisa zvakare uye zvinowanzoraswa. Silver electrophoresis inogona kuchengetwa kweanopfuura gore 1 pasina discoloration.
5 pfuti nhema
Metal material nickel/zinc alloy Ni/Zn), inonziwo pfuti nhema kana nickel nhema. Muvara weplating wakasviba, zvishoma grey. Kugadzikana kwepamusoro kwakanaka, asi kunowanzoita mavara pamazinga akaderera. Iri ruvara rweplating pacharo rine nickel uye haigone kushandiswa nickel-isina plating. Iyo color plating haisi nyore kugadzirisa zvakare uye kugadzirisa.
6 nickels
Nickel (Ni) ipfumbu-chena uye isimbi ine kusimba kwakanyanya uye kuoma. Iyo inowanzo shandiswa sechisimbiso chisimbiso che electroplating kuvandudza hupenyu hwesevhisi ye electroplating. Iine kugona kucheneswa kwakanaka mumhepo uye inogona kuramba ngura kubva mumhepo. Nickel yakaoma uye ine brittle, saka haina kukodzera kune zvigadzirwa zvinoda deformation panguva ye electroplating. Kana nickel-plated zvigadzirwa zvakaremara, iyo yekupfekedza inodonha. Nickel inogona kukonzera kusagadzikana kweganda mune vamwe vanhu.
7 Nickel-isina tin-cobalt plating
Izvo zvinhu ndeye tin-cobalt alloy (Sn / Co). Ruvara dema, padhuze nepfuti nhema (yati pfumbu zvishoma pane pfuti nhema), uye isimbi isina nickel isina. Iyo yepamusoro inenge yakagadzikana, uye yakaderera mwero we electroplating unowanzoita ruvara. Iyo color plating haisi nyore kugadzirisa zvakare uye kugadzirisa.
8 pearl nickel
Chinhu chayo chinonzi nickel, chinonziwo jecha nickel. Inowanzo shandiswa seye pre-yakaputirwa pasi pasi yefog color process. Gray muruvara, isina-inopenya girazi pamusoro, ine mhute yakapfava-yakaita senge satin. Dhigirii yeatomization haina kugadzikana. Pasina kuchengetedzwa kwakakosha, nekuda kwesimba rejecha-kuumba zvinhu, panogona kuve nekushanduka kwemavara pakusangana neganda.
9 ruvara rwemhute
Iyo yakavakirwa pearl nickel kuwedzera pamusoro pemavara. Iine fogging effect uye ine matte. Yayo electroplating nzira ndeye pre-plated pearl nickel. Nekuti iyo atomization mhedzisiro yepearl nickel inonetsa kudzora, iyo ruvara rwepamusoro haruna kuenderana uye rinowanzoita mutsauko weruvara. Uyu ruvara rweplating harugone kushandiswa ne nickel-isina plating kana nedombo mushure mekuputira. Iyi plating color iri nyore kuita oxidize, saka kutarisisa kwakakosha kunofanirwa kubhadharwa kune dziviriro.
10 bhurashi waya plating
Mushure mekugadzira mhangura, mitsetse inoputirwa pamhangura, uye ipapo ruvara rwepamusoro runowedzerwa. Pane pfungwa yemitsara. Chitarisiko chayo ruvara chakangofanana neicho cheyakajairwa plating ruvara, asi mutsauko ndewekuti pane mitsara pamusoro. Waya dzekukwesha hazvigone kuve nickel-isina plating. Nekuda kweiyo nickel-isina plating, hupenyu hwavo hahugone kuvimbiswa.
11 sandblasting
Sandblasting zvakare imwe yenzira dze electroplating fog color. Iyo copper plating inoputirwa nejecha uye ipapo electroplated. Iyo matte pamusoro ijecha, uye iwo akafanana matte color iri pachena kupfuura jecha mhedzisiro. Kufanana nebhurashi plating, nickel-isina plating haigone kuitwa.
