Electroplating n'ụlọ - kacha mkpa n'ime ya mmiri

Ikekwe, e nweghị ụlọ ọrụ, enweghị mgbe ọ ga mkpa iji kpuchie onwe arụpụtara ihe oyi akwa nke zinc, chromium, ọla kọpa ma ọ bụ nickel. Ndị a coatings nwere ike ọ bụghị nanị na-eme ka metal ya ekweghị mara mma anya, ma na-eme ka o kwe omume na-echebe ha si na gburugburu ebe obibi mmetụta, nakwa dị ka na-enye ngwaahịa Njirimara nke nke na-adịghị mbụ pụta ụwa nime ya.

Eme, nke na-enye ohere a mkpa oyi akwa nke metal n'elu nke ngwaahịa na-enye gị ohere iji chebe ikpeazụ si corrosion na-enye ya a ji achọ atụmatụ akpọ electroplating na electroplating na a mfe okwu. Electroplating n'ụlọ - nnọọ a-ahụkarị na mba anyị, n'ihi na na-enwe ngwá maka electroplating n'ụlọ ma ọ bụ na-arụzi ụgbọala, onye ọ bụla nwere ike mepụta ya chrome plating, zinc plating, ọla kọpa plating, nickel plating nke niile metal ngwaahịa.

N'ezie, arụrụ n'ụlọ electroplating presupposes ịdị adị nke ụfọdụ ngwá, nakwa dị ka ihe ọmụma na ubi nke electrochemical - ime na-enweghị ya na cover site electrolysis.

Otu n'ime ndị isi components nke ga-onye ọ bụla nwere n'ụlọ electroplating bụ galvanic bath. Ndị na-esonụ ga-atụle otu n'ime ụzọ ndị ha rụpụta. Onye ọ bụla kpebiri na ọ chọrọ electroplating n'ụlọ, ha chere nsogbu nke-esi mee ka ndị plating saa ma ọ bụ ịgbanwe ya n'okpuru ọ bụla ikike.

Ya mere, e nwere otu ọnụ ngwọta nsogbu a. Ọtụtụ ụlọ ọrụ na-ere ọgwụ na-eji pụrụ iche plastic containers. Onye ọ bụla akpa obreshechena na ekpokọtara na pallets. Ọ bụ nke a ikike ịbụ ndị na-esi na-eji nke plating bath.

Mgbe akpa napụta na arụnyere ga-enyocha bipu ya top. Bee akụkụ nke ọzọ bara uru - ọ ga-mere si bath cover. Na nsọtụ nke bath a na-eme atọ oghere nke ga-arụnyere anode mkpara. N'ezie, oghere ga-abụ na otu larịị.

The cover nke plating bath kwesịrị amanyere bụ iwu. Mgbe e mesịrị na ọ na-kpọgidere na tub site a mgbabere uzo, ihe atụ, piano. Iji mechie, nke a ga-nyere n'etiti cover na-asa zuru okè roba akàrà maka ụgbọ ala ụzọ - na ha na-ere mgbe ọ bụla akpaaka shop na a ga-kụrụ gburugburu perimeta nke bath rim. Mgbe wụnye cover, ọ ga-dabara snugly na bath rim.

N'ihi ya, a bath na a tụgharịa mkpuchi, n'aka nke ya, na-enwe a ndochi onu, nke a na-atụ aro iji ijikọ ventilashion sooks.

Na mbụ ghọtara n'oghere ibo etinyere n'ime ọla kọpa mkpara. Ha ga-eji dị ka ọla kọpa akpa nke kwesịrị ekwesị dayameta - 20mm. Na ikpe, ma ọ bụrụ na ndị tube na-adịghị nwere zuru ezu rigidity, ọ na-etinyere n'ime ígwè mmanya. Na nsọtụ akpa mkpa iha aha, na mgbe ahụ akuakuzinwo n'oghere ha ekemende jikọọ ha a rectifier.

Ná mmechi, anyị na-ewetara ihe atụ nke otu nzọụkwụ nke Filiks na nwere ike rụrụ na n'elu bath - galvanizing. Nzọụkwụ ndị a na-anọchi anya:

- degreasing isiokwu ihe organic mgbaze;

- chemical degreasing na alkali ihe;

- saa ngwaahịa na mmiri ọkụ ;

- electrochemical degreasing na alkaline ngwọta;

- ṅachasịrị na mmiri ọkụ;

- ṅachasịrị mmiri oyi;

- ebighị ma ọ bụ pickling;

- Kpọmkwem galvanizing;

- ghọta itughari ngwọta nke nitric acid (nhọrọ);

- passivation;

- ṅachasịrị mmiri oyi;

- saa na mmiri ọkụ, a okpomọkụ nke banyere 40 ° C ma ọzọ;

- ihicha nke okokụre ngwaahịa.
