1. Cyanide galvanization
Cyanide galvanizing, n'ihi ike mgbasa ya dị elu na ịdị mma nke mkpuchi. N'oge gara aga, ọ nọ n'ọnọdụ dị mkpa na ụlọ ọrụ electroplating. Agbanyeghị, n'ihi oke nsị nke cyanide n'onwe ya na ihe egwu nwere ike ibute gburugburu ebe obibi. Ojiji ya dị oke mma. Agbanyeghị, mmepe nke obere cyanide (microcyanide) galvanizing. Na-eme ka o kwe omume ijide n'aka na ngwaahịa ahụ dị mma ma belata ihe egwu gburugburu ebe obibi. N'okpuru usoro galvanizing cyanide, ịdị mma nke ngwaahịa ahụ dị mma mgbe ekpuchichara akụkụ ngwaike nke caster ahụ. Karịsịa mgbe agba agba agbachara, agba ndị ahụ na-adịgide ruo ogologo oge.
2, usoro na echiche ndị metụtara njikọta nke zincate galvanized caster
Usoro zinc galvanization bụ ihe ọzọ dị mma maka gburugburu ebe obibi karịa cyanide galvanizing. Ugbu a, a na-ekewa ha n'ime usoro "DPE" nke Wuhan Institute of Materials Protection na usoro "DE" nke Guangdian Institute. Ha abụọ bụ zincate galvanized na ihe mgbakwunye alkaline. O nwere njirimara nke nhazi lattice columnar nke plating, ezigbo iguzogide corrosion, ma dabara adaba maka galvanizing agba. Usoro ya na-ahụkarị gụnyere NaOH, ZnO, na ihe mgbakwunye pụrụ iche. Dịka ọmụmaatụ, njikọta nke "DPE-II" na ethanolamine. Usoro a chọrọ njikwa siri ike nke ihe mejupụtara ihe ngwọta plating na ọnọdụ usoro. dịka pH, okpomọkụ, na njupụta ugbu a. iji hụ na mma nke plating ahụ. Mgbe ngwaahịa ahụ hapụrụ tankị ahụ, ọ ga-agafe usoro usoro nhazi mgbe emechara ya. dịka ịsacha, ịchacha, passivating na nkụ. maka nsonaazụ kacha mma.
3. Mgbakwunye chloride galvanization
A na-ejikarị usoro galvanization chloride eme ihe n'ụlọ ọrụ ihe mkpuchi ngwaike caster. Pasentị ahụ karịrị 40%. Ọdịdị passivated (acha anụnụ anụnụ-ọcha ma ọ bụ ọlaọcha-ọcha) nke usoro ahụ yiri nke chrome plating.Ọ dịkwa ọnụ ala. Usoro ndị a na-ejikarị eme ihe maka galvanization chloride gụnyere KCl, ZnCl_2, H_3BO_3 (buffer), na ihe ndị na-eme ka agba dị iche iche pụta ìhè. Usoro a dabara adaba karịsịa maka passivation ọcha (acha anụnụ anụnụ-ọcha, ọlaọcha-ọcha). N'ime ha, passivation ọlaọcha-ọcha n'ihi agba ya kwụsiri ike. A na-ahọrọkarị ya dị ka nhọrọ mbụ. Agbanyeghị, ọ dị mkpa ịmara na mkpuchi galvanized chloride, mgbe a na-ekpughere ya na ikuku ruo ogologo oge, bụ akpụkpọ ahụ na-enwekarị mgbanwe agba. Ọ na-emetụta ọdịdị na iguzogide nchara nke ngwaahịa ahụ. Ya mere. N'omume, ọ dị mkpa ime ihe kwesịrị ekwesị iji gbochie mgbanwe agba.
4. Mkpọpụta ọla kọpa sulfate
Usoro galvanizing sulfate, yana ọnụ ahịa dị ala na adabara maka mkpuchi na-aga n'ihu (dịka ọmụmaatụ, waya, eriri, wdg). Ebe dị na ụlọ ọrụ electroplating. Usoro ndị a na-ahụkarị maka usoro a gụnyere ZnSO_4, H_3BO_3, na ihe ndị na-eme ka ihe dị mma. A na-achịkwa uru pH nke galvanizing sulfate n'etiti 4.5 na 5.5. Site na ịgbanwe nhazi nke ngwọta mkpuchi na ọnọdụ usoro, enwere ike nweta mkpuchi A nwere ezigbo nguzogide corrosion na ìhè. Agbanyeghị. Ma e jiri ya tụnyere usoro galvanizing ndị ọzọ, galvanizing Sulfate nwere ike ịdị obere ma e jiri ya tụnyere nchapụta na nha nha nke mkpuchi ahụ.
