Waa maxay Anodizing

Ka dib markii Chengshuo Hardware injineerada farsamada ay dhamaystireen farsamaynta saxda ah iyo nooca tijaabada cabbirka alaabta birta, waaxdayada wax soo saarka waxay samayn doontaa habayn badan oo la sifeeyay ka dib badeecooyinka birta iyadoo la raacayo deegaanka ay macaamiishu ku isticmaalaan alaabta birta ah.

Dad badan ayaa ka fikira daaweynta dusha sare, waxaana laga yaabaa inay u tixgeliyaan kaliya inay tahay dhammaystirka bilicsanaanta sida rinjiga iyo dahaarka budada si qaybaha ay u muuqdaan kuwo qurux badan oo midab beddela.Dhab ahaantii, daaweynta dusha ma aha oo kaliya qurxinta.Daawaynta dusha kala duwan ayaa lagu daaweeyaa bannaanka alaabta birta iyadoo la marinayo lakab khafiif ah oo dheeri ah oogada.Daaweynta dusha ku habboon waxay ka caawin kartaa noocyada kala duwan ee saxda ah ee birta alaabada la warshadeeyay inay helaan ilaalin wanaagsan jawiga isticmaalka (sida iska caabbinta daxalka, miridhku hoos u dhigo), ilaalinta alaabta birta ah, iyo in la gaaro yoolka lagu kordhinayo nolosha adeegga.

Maanta waxaan kuu soo bandhigi doonaa wax soo saarka aluminiumka iyo daaweynta dusha sare, anodizing, kaas oo Chengshuo Hardware uu si gaar ah xirfad ugu leeyahay.

Waa maxay anodizing?

Anodizing waa habka korantada kiimikaad kaas oo u beddela birta oogada oogada qurxin, waarta, iyo daxalka u adkaysta oogada anode oksaydh.Aluminiumku aad buu ugu habboon yahay anodizing, inkastoo biraha kale ee aan birta ahayn sida magnesium iyo titanium ay sidoo kale noqon karaan anodized.

Sannadkii 1923-kii, anodizing ayaa markii ugu horreysay lagu dabaqay miisaan warshadeed si looga ilaaliyo qaybaha aluminium ee diyaaradaha badda inay daxaloobaan.Maalmihii hore, chromic acid anodizing (CAA) ayaa ahaa habka la door biday, mararka qaarkood waxaa loo yaqaan habka Bengough Stuart, sida lagu qeexay Qeexitaanka Difaaca UK DEF STAN 03-24/3.

Kala soocida caanka ah ee hadda jirta ee anodizing

Anodizing ayaa si weyn loogu isticmaalay warshadaha muddo dheer.Waxaa jira siyaabo badan oo loo isticmaalo magacyo kala duwan, waxaana jira dhowr hab oo kala saarista kuwaas oo lagu soo koobi karo sida soo socota.

Lagu kala saaray nooca hadda: DC anodizing;anodizing AC;Iyo anodizing garaaca wadnaha hadda, kaas oo gaabin kara waqtiga wax soo saarka si loo gaaro dhumucdiisuna waxay u baahan yahay, ka dhigi lakabka filimka qaro weyn, labis iyo cufan, oo si weyn u hagaajin iska caabin daxalka.

Marka loo eego elektrolytka, waxaa loo qaybin karaa sulfuric acid, oxalic acid, chromic acid, acid isku dhafan, iyo oxidation anodic dabiici ah oo midab leh oo leh acids organic acids sida xalka ugu weyn.Oxalic acid anodizing waxaa laga shatiyeeyay Japan 1923 ka dibna si weyn loogu isticmaalay Jarmalka, gaar ahaan codsiyada dhismaha.Anodized aluminium oxide extrusion wuxuu ahaa qalab dhisme oo caan ah 1960-meeyadii iyo 1970-meeyadii, laakiin markii dambe waxaa lagu bedelay balaastiig ka jaban iyo daahan budo ah.Hababka phosphoric acid ee kala duwan ayaa ah mid ka mid ah horumarkii ugu dambeeyay ee daawaynta ka hor ee qaybaha aluminium ee loo isticmaalo isku xidhka ama rinjiyeynta.Isbeddellada kala duwan ee kakan ee geeddi-socodka oksaydheynta anodic iyadoo la adeegsanayo fosfooraska acid ayaa weli soo koraya.Isbeddelka heerarka militariga iyo warshadaha waa in la kala saaro hababka anodizing ee ku saleysan sifooyinka dahaarka marka lagu daro aqoonsiga kimistariga habka.

Marka loo eego sifooyinka lakabka filimka, waxaa loo qaybin karaa: filim caadi ah, filim adag (filim qaro weyn), filim dhoobo ah, lakabka wax ka beddelka dhalaalaya, lakabka xannibaadda semiconductor, iwm.

Kala soocida Hababka Anodizing ee Alaabooyinka Aluminiumka ah

Habka Anodizing ayaa mararka qaarkood loo isticmaalaa mashiinnada aluminium-ka qaawan (aan dahaarka lahayn)Dahaarka Anodic waxaa ka mid ah chromic acid (CAA), sulfuric acid (SAA), phosphoric acid, iyo boric acid sulfuric acid (BSAA) hababka anodizing.Nidaamka anodizing-ku wuxuu ku lug leeyahay daaweynta elektrolytka ee birta, kaas oo filim ama daahan deggan lagu sameeyay dusha birta.Dahaarka Anodic waxaa lagu samayn karaa on Alloys aluminium ee electrolytes kala duwan iyadoo la isticmaalayo hadda beddelka ama toos ah.

Anodizing waxaa lagu gaaraa iyada oo la geliyo aluminium qubeyska aashitada ah ee elektrolytka iyo in hadda la dhex maro dhexdhexaad.Cathode waxaa lagu rakibay gudaha taangiga anodizing;Aluminiumku wuxuu u shaqeeyaa sidii anode, oo sii daaya ions ogsijiinta ee elektrolytka oo ku xidha atamka aluminium ee dusha qaybta anodized.Sidaa daraadeed, anodizing waa oksaydh si heer sare ah loo xakameyn karo taas oo kor u qaadaysa ifafaalaha dabiiciga ah.

Anodization waxaa ku jira Nooca I, Nooca II, iyo Nooca III.Anodizing waa habsocod koronto ah oo loo isticmaalo in lagu kordhiyo dhumucda lakabka oksaydhka dabiiciga ah ee dusha sare ee qaybaha aluminium.Qaybaha aluminiumku waa anodized (sidaa darteed loo yaqaan "anodizing"), iyo qulqulka hadda u dhexeeya iyaga iyo cathode (sida caadiga ah usha aluminium siman) iyada oo loo marayo korantada kor ku xusan (inta badan sulfuric acid).Shaqada ugu weyn ee anodizing waa in la kordhiyo iska caabbinta daxalka, xidhashada caabbinta, dhejinta rinjiga iyo primer, iwm.

PIC waxaa qoray Corlee:Nooca IIIqaybo aluminium anodized

Qaab dhismeedka oksaydhka anode wuxuu ka yimid substrate aluminium wuxuuna gabi ahaanba ka kooban yahay aluminium oxide.Nooca aluminiumka ah laguma dabaqo dusha sare sida rinjiga ama dahaarka, laakiin si buuxda ayaa loogu dhex daray aluminiumka hoose ee hoose, sidaa darteed ma jabin doono ama ma dillaaci doono.Waxay leedahay qaab-dhismeed dalool ah oo aad loo dalbay waxaana lagu samayn karaa habayn heer sare ah sida midabaynta iyo xidhitaanka.
