Taa, anyị ga-ewebata gị aluminom ngwaahịa mmepụta na elu ọgwụgwọ, anodizing, nke Chengshuo Hardware bụ ọkachamara karịsịa na.

Gịnị bụ anodizing?

Anodizing bụ usoro electrochemical nke na-agbanwe elu igwe ka ọ bụrụ ihe ịchọ mma, nke na-adịgide adịgide na elu anode oxide na-eguzogide corrosion.Aluminom dị ezigbo mma maka anodizing, ọ bụ ezie na ọla ndị ọzọ na-adịghị ferrous dị ka magnesium na titanium nwekwara ike ịbụ anodized.

N'afọ 1923, e bu ụzọ tinye anodizing n'ọtụtụ ụlọ ọrụ mmepụta ihe iji chebe akụkụ aluminom nke ụgbọ elu mmiri site na corrosion.N'oge mbụ, chromic acid anodizing (CAA) bụ usoro kachasị amasị, mgbe ụfọdụ a na-akpọ usoro Bengough Stuart, dị ka akọwara na UK Defence Specification DEF STAN 03-24/3.

Nkewa na-ewu ewu ugbu a nke anodizing

A na-eji Anodizing eme ihe na ụlọ ọrụ ruo ogologo oge.Enwere ọtụtụ ụzọ isi jiri aha dị iche iche, ma enwere ọtụtụ ụzọ nhazi ọkwa nke enwere ike ịchịkọta dịka ndị a:

Nkewa site na ụdị ugbu a: DC anodizing;AC anodizing;Na usu ugbu anodizing, nke nwere ike ebelata mmepụta oge iji nweta chọrọ ọkpụrụkpụ, mee ka film oyi akwa oké, edo na ok, na budata mma corrosion eguzogide.

Dị ka electrolyte si kwuo, enwere ike kewaa ya na sulfuric acid, oxalic acid, chromic acid, mix acid, na anodic oxidation na-acha uhie uhie na sulfonic organic acids dị ka isi ngwọta.Oxalic acid anodizing bụ patented na Japan na 1923 ma mesịa jiri ya mee ihe na Germany, karịsịa na ngwa owuwu.Anodized aluminum oxide extrusion bụ ihe ewu ewu ewu na 1960s na 1970s, ma e mesịrị dochie ya ọnụ ala plastics na ntụ ntụ mkpuchi.Usoro phosphoric acid dị iche iche bụ otu n'ime ihe ọhụrụ na-eme tupu ọgwụgwọ nke akụkụ aluminom ejiri maka njikọta ma ọ bụ eserese.Mgbanwe dị mgbagwoju anya dị iche iche na usoro oxidation anodic site na iji phosphoric acid ka na-etolite.Usoro nke ụkpụrụ agha na ụlọ ọrụ mmepụta ihe bụ ịhazi usoro anodizing dabere na njirimara mkpuchi na mgbakwunye na ịchọpụta kemịkalụ usoro.

Dị ka ihe onwunwe nke ihe nkiri oyi akwa, ọ nwere ike kewaa: nkịtị film, siri ike film (oke film), seramiiki film, na-egbuke egbuke mgbanwe oyi akwa, semiconductor mgbochi oyi akwa, wdg maka anodizing.

Nkewa nke Usoro Anodizing maka Ngwaahịa Aluminom

A na-eji usoro anodizing eme ihe mgbe ụfọdụ maka igwe aluminom ekpughere (anaghị ekpuchi ya) ma ọ bụ akụkụ a na-egweri kemịkalụ nke chọrọ nchebe mgbochi corrosion.Anodic mkpuchi gụnyere chromic acid (CAA), sulfuric acid (SAA), phosphoric acid, na boric acid sulfuric acid (BSAA) anodizing usoro.Usoro anodizing na-agụnye ọgwụgwọ electrolytic nke ọla, nke a na-emepụta ihe nkiri ma ọ bụ mkpuchi kwụsiri ike n'elu igwe.Enwere ike ịmepụta mkpuchi anodic na aluminom alloys na electrolytes dị iche iche na-eji ma ọ bụ ugbu a na-agbanwe agbanwe ma ọ bụ ugbu a.

A na-enweta anodizing site n'itinye aluminom n'ime bat electrolyte acidic ma na-agafe ugbu a site na ọkara.A na-etinye cathode n'ime tankị anodizing;Aluminom na-arụ ọrụ dị ka anode, na-ahapụ ion oxygen site na electrolyte ma na-ejikọta na aluminom atom n'elu akụkụ anodized.Ya mere, anodizing bụ oxidation nke a na-achịkwa nke ukwuu nke na-eme ka ihe ndị dị n'okike dịkwuo elu.

Anodization gụnyere Ụdị I, Ụdị II, na Ụdị III.Anodizing bụ usoro passivation electrolytic eji eme ka ọkpụrụkpụ nke oyi akwa oxide dị n'elu akụkụ aluminom.Aluminom components bụ anodized (ya mere a na-ezo aka dị ka "anodizing"), na ugbu a na-aga n'etiti ha na cathode (na-emekarị aluminom mkpanaka ewepụghị) site n'elu nke e kwuru n'elu electrolyte (kasị sulfuric acid).Isi ọrụ nke anodizing bụ ịbawanye nguzogide corrosion, iyi nguzogide, adhesion na agba na primer, wdg.
