Hordhac kooban

Aluminiumka aluminiumka ah ama aluminiumka aluminiumka ah ayaa lagu dhejiyaa xal elektrolyt ah oo loogu talagalay daaweynta galvanization, iyo habka sameynta filimka aluminium oxide ee dusha sare ee korantada waxaa lagu magacaabaa daaweynta anodized ee aluminium iyo aluminium aluminium.Ka dib daaweynta oksaydhka anodic, dusha aluminiumku wuxuu soo saari karaa dhowr microns - boqollaal microns of film oxide.Marka la barbar dhigo filimka oxide dabiiciga ah ee aluminium aluminium, caabbinta daxalka, xirashada caabbinta iyo qurxinta ayaa si cad loo hagaajiyay oo la hagaajiyay.

Mabda'a aasaasiga ah

Mabda'a oksaydhka anodic ee aluminiumku asal ahaan waa mabda'a hydroelectrolysis.Marka koronto la gudbiyo, falcelinta soo socota ayaa dhacda:
Kathode-ka, H2 waxaa lagu sii daayaa sida soo socota: 2H + + 2e → H2
At anode ah, 4OH-4E → 2H2O + O2, Ogsajiinta soo dejiyey ma aha oo kaliya ogsijiin molecular (O2), laakiin sidoo kale oxygen atomiga (O) iyo ogsijiin ionic (O-2), sida caadiga ah lagu muujiyay sida oxygen molecular ee falcelinta.
Sida anode ahaan, aluminiumku waa oksijiinta oksijiinta oksijiinta si ay u sameyso filim Al2O3 oo aan biyo lahayn: 2AI + 3[O] = AI2O3 + 1675.7kj Waa in la tilmaamaa in dhammaan oksijiinta la soo saaro aysan la falgelin aluminium, laakiin qaar ka mid ah oo ka mid ah waxa uu ku soo degdegay qaab gaas ah.
Anodic oxidation ayaa muddo dheer si weyn loogu isticmaalay warshadaha, sidaaluminium CNC qaybaha machining.Ka dib markii anodized, qaybaha mashiinada aluminium CNC heli karaan muuqaal cajiib ah iyo awoodda antioxidant wanaagsan.

Waxaa jira siyaabo badan oo lagu calaamadiyo magacyo kala duwan, kuwaas oo lagu soo koobi karo sida soo socota.
Sida laga soo xigtay nooca hadda, waxa loo qaybin karaa anodizing toos ah hadda, beddelka anodizing hadda, iyo pulsed anodizing hadda, taas oo soo gaabin karta wakhtiga wax soo saarka si ay u gaaraan dhumucda loo baahan yahay, lakabka filimku waa dhumuc iyo lebis iyo cufan, iyo iska caabin ah daxalka. si weyn ayaa loo hagaajiyay.
Sida laga soo xigtay electrolyte: sulfuric acid, oxalic acid, chromic acid, acid isku dhafan iyo xal sulfonic acid organic ee oxidation anodic midabka dabiiciga ah.
Marka loo eego sifooyinka filimka, waxaa loo qaybin karaa filim caadi ah, filim adag (filim qaro weyn), filim dhoobo ah, lakabka wax ka beddelka dhalaalaya iyo lakabka xannibaadda ee ficilka semiconductor.
Habka anodizing ee tooska ah ee elektrosulfuric acid ee tooska ah ayaa ah midka ugu caansan, sababtoo ah waxay ku habboon tahay aluminium anodizing iyo inta badan aluminium aluminium. lakabka filimku waa dhumuc weyn, adag oo xiran-u adkaysta, iyo iska caabin ka fiican oo iska caabin ah ayaa la heli karaa ka dib marka la xiro godka. lakabka filimku waa mid aan midab lahayn oo hufan, oo leh awood adsorption xoog leh iyo midab fudud. Waxqabadka hooseeya, isticmaalka tamarta yar; Geedi socodka uma baahna inuu beddelo wareegga danabka, kaas oo ku habboon wax soo saarka joogtada ah iyo qalabaynta hawlgalka la taaban karo; Sulfuric acid waa waxyeello yar marka loo eego chromic acid, sahayda ballaaran, faa'iidooyinka qiimo jaban.
