Daaweynta cudurka loo yaqaan 'dawada loo yaqaan' anoizing 'waxaa loo qaybiyaa afar talaabo oo aasaasi ah, kuwaas oo ah ka-hortagga, Daaweynta loo yaqaan 'anodic chopidation', midabaynta daaweynta ee cathodic, iyo daaweyn dahaad oo dabiici ah. Hawsha gaarka ahi waa sida soo socota.
Ka-hortag, ka-hortag iyo waxaa ku jira shan talaabo.
- Daaweynta deganaanshaha: Ujeeddadu waa in laga saaro saliidaha iyo wasakhda kale ee dusha sare ee badeecada, Si loo hubiyo in nidaamka wax lagu dhaqo ee alkalali, Dhismaha dusha sare ee sheyga waa labis, Si loo wanaajiyo tayada waxyaabaha soosaarka ah. Daaweynta deganaanshaha ayaa guud ahaan loo adeegsadaa uruurinta 5-25% acid sulfuric, heerkulka deganaanshaha ee 60-80c.
- Daaweynta Daaweynta: Ujeeddadiisu waa in la sii daayo wasakhda dusha sare ee sheyga, iyo dhumucdii dusha sare ee qiyaastii 25-1000na filimka dabiiciga ah ee dabiiciga ah ayaa laga saaray, si dusha sare ee birta salka u soo shaac baxday, Si loo fududeeyo horumarka si habsami leh ee loo yaqaan 'oksing' iyo midabaynta, guud ahaan isticmaalka 40-80 Darajooyinka nah.
- Daaweynta Daaweynta: Ujeeddadu waa in meesha laga saaro badeecadaha madow ee ka harsan dusha sare ee sheyga ka dib, Si loo helo meel bir ah oo dhalaalaya.
- Daaweynta Daaweynta: Ujeeddadu waa in la sameeyo aluminium ama waxyaabaha aluminiumka ah iyada oo aan laheyn luster dusha sare si loo abuuro dusha sare ee daweyn dhalanteed ah, samaynta jiirka dhibicda, guud ahaan iyadoo la adeegsanayo 20-40C ammoniaium foloraydhka.
5, Daaweynta Daaweynta: Si looga takhaluso burburka farsamada iyo dhibco dhibco ah dusha sare ee waxyaabaha aluminium ah, Hagaajinta salka dusha sare iyo qoto dheer oo qoto dheer guud ahaan si loo daweeyo.
Daweynta Daweynta
Mabda 'Aasaasi ah: aluminium cathodic oxidation waa asal ahaan waa elektrolysis-ka biyaha, Marka biyaha electrolysis-ka uu dhaco o2- ion iyo falcelin aluminium ah oo sameeya aluminium oxide (Al2o3) Xulashada General Electrolyte ee Sulfuric acid, chromic acid, acid phosphoric, oxalic acid, In ku saabsan 0C sulfuric acid si ay u sameeyaan filim adag oo oxide adag. Agabyo kala duwan ayaa saameyn weyn ku leh filimka oxida. Loogu tala-galay 6000 taxanaha at (6063.6061.6065), Kaliya ma aha oo keliya filimka okside-ka ah waa la sameyn karaa, Laakiin sidoo kale waxay xijahaysaa filim okside ah, iyo filim okside dhalaalaya, Laakiin loogu talagay aluminium aluminium, Filimka oxide ee difaaca ayaa la sameyn karaa, Laakiin filimka dheeh ah ee filimka okside guud ahaan wuxuu sameyn karaa oo keliya midab xoog leh.
Midabaynta midabaynta ee cathodic, Waxaa jira dhowr habab oo lagu muujiyo daaweynta daaweynta sida soo socota.
Habka midabka elektrolytic.
Habka waa: Qeybta Aluminium Offinum-ka ka dib markii anodic oksiting waxaa lagu ridayaa elektaroonigga ah ee milixda birta ah iyo mar labaad, si codadka cusbada birta lagu shubo meesha ugu hooseeya ee filimka okside pinhole iyo midab leh, oo midabka naxaasta iyo midabka madow waxaa lagu heli karaa codsi wax ku ool ah, badiyaa xalka milixda ee ni,CO,Sn sida electrolyte, inta badan sulfate, AC Electrolysis.
Qaabka dheeh
Habka waa: Dhex dhig qaybaha caadiga ah ee aluminiumka aluminiumka xalka ay ku jirto xalka ay ka kooban yihiin dyes, Kadib filimka okside-ka ah ee okhole ashyaa'da iyo midabaynta, Qaabka dheehaynta Filimka Filimka filimka sulfuric acid waa kan ugu fiican, Meesha ay wakiilku matalaan wakiilku waa ammonium oxiote (dahab dahab ah oo jaalle ah) Cobalt Acetate (midab naxariiska ah) Cathodic Oxide Filimka Dhuqan ka dib baahida loo qabo in la daboolo godka, Waxaa jira laba hab oo waaweyn.
- Godka Nickel cusbada: Iyada oo leh iska caabin cimilo wanaagsan.
- Biyo karkaraya: Cilladu waa in dheehku ay fududahay in la daboolo markii ay xidhaan godka sababa codkan aan sinnayn.
Daaweynta Darajooyinka Nooca dabiiciga ah
Ka dib kathodic Oktion iyo midabaynta midabaynta aluminium, Si loo wanaajiyo iska caabinta iska caabinta iyo rarida saameynta xamuulka, Daaweynta dahabka ee dabiiciga ah waa la fulin karaa.
Dahaadh koronto
Atomize rinjiga leh cabirka walxaha ka kooban oo wanaagsan ka dibna ku afuufo dusha sare ee shayga si loo dahaarka ka dhigo in ay noqoto mid ku lifaaqan, Guud ahaan ka dhig walxaha rinjiga ee lagu eedeeyo cathode marka hore, isla mar ahaantaana ku codso korantada 100kv dc ee shayga lagu daboolo cathode, Rinjiga guud ahaan waxaa lagu xushay resin acrylic.
Xarkaha elektaroonigga ah
Xalka aqueous ee acrylic resin, Filimka okside-ka waxaa loo isticmaalaa maadaama catke iyo elektrolysis lagu fuliyo iyada oo ay la socoto 200V koronto si ay u sameeyaan filimka okside-ka ee ku dahaarka leh filim dahab ah
