① Ọgwụgwọ elu profaịlụ aluminom:
Ngwọta elu nke profaịlụ aluminom, nke a makwaara dị ka pretreatment elu, bụ iji ihe anụ ahụ na kemịkal wepụ ihe ruru unyi n'elu profaịlụ aluminom, nke mere na a na-ekpughe profaịlụ aluminom, nke dị mma maka ọgwụgwọ oxidation nke aluminom. elu profaịlụ.
② Usoro mmebi elu profaịlụ aluminum:
Ebumnuche nke usoro nbipu maka profaịlụ aluminom bụ iji wepụ mmanụ na-agba mmanụ ụlọ ọrụ na mmanụ mgbochi corrosion n'elu profaịlụ aluminom, yana unyi na adịghị ọcha na-agbaso elu profaịlụ, iji hụ na corrosion alkali edo edo nke profaịlụ aluminom, na iji hụ na ịdị ọcha nke tankị etching alkali;na iji melite ogo ọgwụgwọ elu nke profaịlụ aluminom.
③ Usoro etching profaịlụ aluminom:
Usoro etching acid dị n'elu profaịlụ aluminom bụ ime ọgwụgwọ corrosion elu acid mgbe emechara profaịlụ aluminom.Ebumnuche bụ isi bụ iwepụ oxides kpụrụ mgbe oxidation nke metal ndị ọzọ dị n'elu profaịlụ aluminum na ihe nkiri oxide na-emepụta site na profaịlụ;ọ dị mkpa ka ọ bụrụ ozugbo ọgwụgwọ corrosion acid gasịrị.Na-arụ ọrụ ịsacha mmiri, a na-achịkwa okpomọkụ nke ịsacha mmiri n'oge dị ka 50 Celsius C iji zere akara nrịbama n'elu profaịlụ, wee kpochaa ya na mmiri na-asọ asọ.Ebe ọ bụ na profaịlụ aluminom nwere ihe ọla kọpa, elu ahụ na-agba ọchịchịrị mgbe corrosion acid gasịrị, ọ dịkwa mkpa ka etinye ya na ngwọta nitric acid maka nkeji 3-5 iji mee ka elu ahụ na-egbuke egbuke.
④ Usoro etching alkaline nke profaịlụ aluminom:
Ebumnuche bụ isi nke usoro alkali etching nke profaịlụ aluminom bụ otu ihe ahụ dị ka usoro etching acid, iji wepụ ihe ndị fọdụrụ na ihe ndị fọdụrụ na metamorphic n'elu profaịlụ aluminom n'oge usoro oxidation, na iwepụ ntụpọ ọkọchị nke fọdụrụ na ya. elu nke profaịlụ aluminom n'oge usoro extrusion;The elu alkali etching ọgwụgwọ na-arụ a dị oké mkpa ọrụ na mkpokọta àgwà nke aluminum profaịlụ elu.
⑤ Usoro mkpochapụ profaịlụ aluminom:
Ebumnuche nke aluminum profaịlụ neutralization usoro bụ iji wepụ ọla kọpa, manganese, ígwè, silicon na ndị ọzọ alloy ọcha ma ọ bụ adịghị ọcha na-anọgide n'elu nke aluminum profaịlụ mgbe acid etching na alkali etching ọgwụgwọ, nke na-adịghị ike na alkaline ngwọta, na neutralize aluminom profaịlụ.A na-ejikarị lye fọdụrụ mgbe ọgwụgwọ alkaline etching gasịrị na-eji ngwọta nitric acid 30%-50%.Maka nnukwu silicon aluminom alloys, tụba n'ime alloys, na-eji ngwakọta nke nitric acid na hydrogen fluoride na oke olu nke 1: 3 acid.Silicon na-emeghachi omume na hydrogen na hydrofluoric acid iji mepụta fluorosilicic acid wee hapụ elu aluminom.
⑥ Anodizing ọgwụgwọ nke aluminom profaịlụ:
Usoro nke anodizing profaịlụ aluminom bụ iji ihe ngwọta dị ka onye na-emepụta ihe, ma jiri nkwụsị n'ọnụ na-emepụta ihe nkiri oxide n'elu profaịlụ aluminom, nke mere na profaịlụ aluminom nwere nnukwu nguzogide corrosion, n'ihi mkpuchi nchebe nwetara. site na profaịlụ aluminom anodized Ọ nwere nnukwu ike na nguzogide corrosion, na ọkọlọtọ ọkọlọtọ bụ 10-12μ, nke nwere ike imeziwanye nguzogide oxidation nke profaịlụ aluminom ma melite mma nke profaịlụ.
Sulfuric acid anodization na-ejikarị 10-20% H2SO4 dị ka electrolyte, na-arụ ọrụ okpomọkụ bụ 15-20 ℃, nke ugbu a njupụta bụ 1-2.5A / dm2, na electrolysis oge dabere na film ọkpụrụkpụ chọrọ, n'ozuzu 20-60min.Isi iyi ike a na-ahụkarị bụ ozugbo.Voltaji etinyere na-agbanwe dabere na conductivity, okpomọkụ na aluminom ọdịnaya nke electrolyte.N'ozuzu, ọ bụ 15-20V.Usoro usoro nwere mmetụta dị ukwuu na arụmọrụ nke akpụkpọ ahụ.
⑦ Aluminom profaịlụ elu akara ọgwụgwọ:
Mgbe profaịlụ aluminom emechara anodized, micropores ga-etolite n'elu, nke dị mfe oxidized na corroded n'oge eji.Akara ọgwụgwọ kwesịrị rụrụ mgbe anodizing ọgwụgwọ.Usoro oghere sitere na Europe), sulfuric acid anodizing na-ejikarị 10-20% H2SO4 dị ka electrolyte, okpomọkụ na-arụ ọrụ bụ 15-20 ℃, njupụta dị ugbu a bụ 1-2.5A / dm2, oge electrolysis na-adabere na ọkpụrụkpụ fim ahụ. chọrọ, n'ozuzu na 20-60min.Isi iyi ike a na-ahụkarị bụ ozugbo.Voltaji etinyere na-agbanwe dabere na conductivity, okpomọkụ na aluminom ọdịnaya nke electrolyte.N'ozuzu, ọ bụ 15-20V.Usoro usoro nwere mmetụta dị ukwuu na arụmọrụ nke akpụkpọ ahụ.
