Ọdịiche dị na Galvanizing, Cadmium Plating, Chromium Plating, na Nickel Plating of Steel Pipe Round Steel

Kedu ihe dị iche n'etiti plating zinc, plating cadmium, plating chromium, na nickel plating nke ígwè ọkpọkọ naígwè bar?

1.Galvanizing

Àgwà: Zinc kwụsiri ike na ikuku kpọrọ nkụ na ọ naghị adị mfe ncha.N'ime mmiri na ikuku ikuku, ọ na-emeghachi omume na oxygen ma ọ bụ carbon dioxide iji mepụta oxides ma ọ bụ alkaline zinc carbonate film, nke nwere ike igbochi zinc ka ọ nọgide na-eme ka oxidize na-arụ ọrụ nchebe.Ihe mkpuchi galvanized n'ozuzu na-enweta ọgwụgwọ passivation.Mgbe passivation na chromic acid ma ọ bụ chromate ngwọta, a kpụrụ passivation film adịghị emetụta ngwa ngwa site iru mmiri ikuku, na-eme ka nke ukwuu mgbochi corrosion ike.Maka akụkụ mmiri, akụkụ ndị nwere mgbidi dị mkpa (mgbidi mgbidi <0.5m), na akụkụ ígwè nke chọrọ ike arụ ọrụ dị elu, a ghaghị ime iwepụ hydrogen, ebe ọla kọpa na ọla kọpa alloy nwere ike ọ gaghị achọ iwepụ hydrogen.Zinc plating nwere ọnụ ala dị ala, nhazi dị mma, yana nsonaazụ dị mma.Ụdị ikike nke zinc dịtụ njọ, ya mere zinc plating bụ mkpuchi anodic na ọtụtụ ọla.Ngwa: Galvanizing na-ejikarị na ọnọdụ ikuku na ebe ndị ọzọ dị mma.Mana ekwesighi iji ya dị ka akụkụ esemokwu

2.Cadmium plating

Njirimara: Maka akụkụ ndị na-abanye na ikuku mmiri ma ọ bụ mmiri mmiri, na na mmiri ọkụ dị elu karịa 70 ℃, cadmium plating na-akwụsi ike, nwere nguzogide corrosion siri ike, mma mmanu mmanu, ma na-agbaze nwayọọ nwayọọ na mmiri hydrochloric acid.Otú ọ dị, ọ na-agbaze nke ukwuu na nitric acid, nke a na-esighị ike na alkali, na oxides ya na-esikwaghị ike na mmiri.Ihe mkpuchi Cadmium dị nro karịa mkpuchi zinc, na-enwe obere brittleness hydrogen na nrapado siri ike.Ọzọkwa, n'okpuru ọnọdụ electrolysis ụfọdụ, mkpuchi cadmium nwetara mara mma karịa mkpuchi zinc.Ma gas nke cadmium na-emepụta n'oge agbaze na-egbu egbu, na nnu cadmium soluble na-egbukwa egbu.N'okpuru ọnọdụ n'ozuzu, cadmium bụ mkpuchi cathodic na ígwè, na mkpuchi anodic na mmiri na okpomọkụ dị elu.Ngwa: A na-ejikarị echebe akụkụ site na corrosion ikuku nke mmiri osimiri ma ọ bụ ngwọta nnu yiri ya na ikuku mmiri jupụtara.Ọtụtụ akụkụ na ụlọ ọrụ ụgbọ elu, igodo, na ụlọ ọrụ eletrọnịkị, isi iyi na akụkụ eri ka ejiri cadmium kpuchie.Enwere ike ịchacha ya, phosphated, ma jiri ya mee ihe dị ka ihe agba agba, mana enweghị ike iji ya mee ihe dị ka tebụl.

3.Chrome plating

Njirimara: Chromium kwụsiri ike na ikuku iru mmiri, alkaline, nitric acid, sulfide, carbonate solution, na acid organic, ọ dịkwa mfe soluble na hydrochloric acid na sulfuric acid na-ekpo ọkụ.N'okpuru ọrụ nke ugbu a kpọmkwem, ọ bụrụ na ejiri oyi akwa chromium mee ihe dị ka anode, ọ na-adị mfe soluble na ngwọta soda caustic.Igwe oyi akwa chromium nwere nchikota siri ike, ike siri ike, 800-1000V, ezigbo mgbochi iyi, ntụgharị ọkụ siri ike, na oke ọkụ.Ọ naghị agbanwe agba n'okpuru 480 ℃, na-amalite oxidize n'elu 500 ℃, na budata ibelata ike ike na 700 ℃.Ọdịmma ya bụ na chromium siri ike, na-agbaji agbaji, ma na-enwekarị ikewapụ ya, nke a na-apụtakarị ma ọ bụrụ na etinyere ya na ibu mmetụta ọzọ.Na o nwere porosity.Metal chromium na-adị mfe na-agafe na ikuku iji mepụta ihe nkiri passivation, si otú ahụ na-agbanwe ikike nke chromium.Ya mere, chromium na-aghọ ihe mkpuchi cathodic na ígwè.Ngwa: Kpọmkwem plating chromium n'elu ígwè akụkụ dị ka mgbochi corrosion oyi akwa adịghị mma, na ọ na-adịkarị enweta site multi-layer electroplating (ie ọla kọpa plating → nickel → chromium) iji nweta nzube nke nchara mgbochi na mma.Ugbu a, a na-eji ya eme ihe n'ịkwalite nkwụsi ike nke akụkụ, ịrụzi akụkụ, ntụgharị ọkụ, na ọkụ ịchọ mma.

nickel plating

Njirimara: Nickel nwere ezigbo nkwụsi ike kemịkalụ na ikuku na ngwọta alkaline, ọ naghị adị mfe ncha, ma ọ bụ naanị oxidized na okpomọkụ n'elu 600 Celsius C. Ọ na-agbaze nwayọọ nwayọọ na sulfuric acid na hydrochloric acid, ma ọ dị mfe soluble na dilute nitric acid.Ọ dị mfe ịfefe na nitric acid gbadoro ụkwụ ya mere ọ nwere ezigbo nguzogide corrosion.Ihe mkpuchi nickel nwere ike siri ike ma dị mfe iji.
