Anodizing tsari

Anodizing tsari ne mai surface jiyya fasaha ga karafa (musamman aluminum da ta gami). Ta hanyar amfani da halin yanzu a cikin takamaiman electrolyte, an samar da fim ɗin oxide mai yawa akan saman ƙarfe. Babban fasali su ne:

Kariya: Fim ɗin da aka kafa na oxide zai iya kare yanayin ƙarfe da kyau kuma ya hana lalata da lalacewa.
Ado: Ana iya rina fim ɗin oxide a launuka daban-daban don haɓaka bayyanar samfurin.
Aiki: Fim ɗin oxide yana da kyau mai kyau, juriya na zafi da juriya na lalata.

Babban matakai
Tsaftacewa: Cire ƙazanta sosai kamar mai da ƙura a saman samfuran aluminium don tabbatar da tsaftataccen wuri. Wannan yawanci ya haɗa da tsabtace sinadarai da hanyoyin yankan inji.
Ragewa: Yi amfani da kaushi ko maganin alkaline don cire mai daga saman don tabbatar da ingancin murfin oxide.
Maganin anodic:
An dakatar da samfurin aluminum akan anode a cikin tantanin halitta na lantarki.
A electrolyte yawanci sulfuric acid, chromic acid, oxalic acid, da dai sauransu Sulfuric acid anodizing ne ya fi kowa.
Bayan an kunna wutar lantarki, an samar da fim din aluminum oxide a saman samfurin aluminum a ƙarƙashin aikin na yanzu. Yawan kauri na wannan fim yana tsakanin 5 zuwa 30 microns, kuma fim ɗin anodized mai wuya zai iya kaiwa 25 zuwa 150 microns.
Jiyya na rufewa: Tun da fim din oxide akan saman samfuran aluminum zai samar da micropores bayan anodizing, ana buƙatar magani na rufewa. Ana iya samun wannan ta hanyar tururin ruwan zafi, nickel plating ko passivation don inganta juriya na lalata da taurin fim din oxide.
Maganin rini (na zaɓi): Bayan maganin rufewa, ana iya nutsar da samfurin aluminum a cikin ruwan 'ya'yan itace mai launi wanda ke ɗauke da rini don ba da damar rini su shiga cikin Layer oxide don samar da fina-finai na oxide na launi daban-daban.
Jiyya na rufewa (na zaɓi): Bayan maganin rini, don ƙara haɓaka juriya na lalata da juriya na Layer oxide, ana iya yin maganin rufewa. Ana yin hakan ne ta hanyar tururin ruwan zafi, hatimin mai, nutsar da ruwan sanyi, da sauransu.

Abubuwa masu tasiri
Abun da ke ciki da ƙaddamarwa na electrolyte: Abun da ke ciki, ƙaddamarwa da tsabta na lantarki zai shafi inganci da aikin fim din oxide.
Yanayin zafi: Yanayin zafin jiki a lokacin tsarin anodizing yana da tasiri mai girma akan ingancin fim din oxide. Gabaɗaya ana sarrafa shi tsakanin debe 15-30 ℃.
Ƙarfin Ionic: Ƙarfin ionic a cikin electrolyte yana da alaƙa kai tsaye da taurin fim ɗin oxide. Lokacin da ƙarfin ionic ya yi ƙasa, ƙarfin fim ɗin oxide kuma yana da ƙasa.
Ƙimar halin yanzu: Ƙaƙƙarfan halin yanzu yana da tasiri mai girma akan kauri da matsakaicin girman pore na fim din oxide. Mafi girma da yawa na yanzu, mafi girma matsakaicin girman girman pore na fim din oxide, kuma kauri na fim ɗin yana ƙaruwa daidai.

Anodizing tsari ne yadu amfani da surface aiki na masana'antu kayayyakin kamar aluminum gami kofofin da windows, lantarki na'urar gidaje, da kuma mota sassa. Yana da mahimmancin fasaha na jiyya na karfe.
