Daawaynta Dusha Aluminium

Daaweynta dusha sare ee aluminiumku waa nidaam adeegsada hab gaar ah si wax looga beddelo dusha sare ee aluminium iyo agabkeeda aluminium, ujeeddadeeduna tahay in la hagaajiyo sifooyinka dusha sare, kor loogu qaado caabbinta daxalka iyo bilicda. Daaweynta dusha aluminium inta badan waxaa ka mid ah anodizing, electroplating, daahan buufin, daaweynta kiimikada iyo hababka kale si ay u buuxiyaan shuruudaha waxqabadka dusha ee alaabta aluminium ee beeraha kala duwan ee warshadaha.

First of dhan, anodizing waa habka daaweynta dusha aluminium caadi ahaan loo isticmaalo. Iyada oo la anodizing walxaha aluminium ee elektrolyt gaar ah, filim cufan oo isku mid ah ayaa la sameeyay, kaas oo wanaajinaya adkaanta dusha sare, xirto caabbinta iyo xirashada caabbinta walxaha aluminium. Iska caabin daxalka.

Filimka oksaydhku wuxuu leeyahay qaab-dhismeed dalool gaar ah wuxuuna ku habboon yahay midabaynta, rinjiyeynta ama xidhitaanka si loo helo midabyo kala duwan iyo saamaynta qurxinta. Habkan daaweynta ayaa si weyn loogu isticmaalaa qaybaha baabuurta, dhismaha derbiyada daahyada, hawada hawada iyo beeraha kale si loo hagaajiyo tayada iyo adeegga dusha sare. nolosha alaabta aluminium.

Marka labaad, koronto-samaynta waa hab kale oo daawaynta dusha sare ee aluminiumka, oo ay ku jiraan dhejinta nikkel, dajinta chromium, dajinta zinc iyo daawaynta kale ee dahaadhka biraha. Dusha sare ee alaabta aluminium ee korantada leh waxay leedahay caabbinta daxalka wanaagsan, bilicda iyo sifooyinka farsamada, waxayna ku habboon tahay qurxinta iyo ilaalinta. Habka korantada ayaa si wax ku ool ah uga hortagi kara daxalka oxidation ee alaabta aluminium, waxay kordhisaa nolosheeda adeegga, waxayna hagaajinaysaa tayada muuqaalka. Waxaa si weyn loogu isticmaalaa qaybaha baabuurta, alaabta guriga, alaabta qurxinta iyo beeraha kale.

daahan buufinta alaabta aluminium sidoo kale waa habka daaweynta dusha caadiga ah. Buufinta resin epoxy, polyester-ka, rinjiga fluorocarbon iyo dahaarka kale kaliya kuma bixin karaan xulashooyinka midabka qani ah iyo saamaynta qurxinta, laakiin sidoo kale si wax ku ool ah uga hortagto alaabta aluminiumka inay xumaato. Daxalka iyo oxidation. Dahaarka buufinta waxay ku habboon tahay daaweynta dusha sare ee albaabbada aluminiumka iyo daaqadaha, qolalka qorraxda, muraayadaha qurxinta aluminium iyo alaabta kale.

Intaa waxaa dheer, daaweynta kiimikaad sidoo kale waa mid ka mid ah hababka daaweynta dusha aluminium ee caadiga ah, oo ay ku jiraan pickling, qooyn, nadiifinta dareeraha iyo hababka kale ee kiimikada, kuwaas oo loo isticmaalo in laga saaro miisaanka oxide iyo wasakhaha dusha sare ee alaabta aluminium si ay u bixiyaan nadiif nadiif ah oo siman. hababka daaweynta ee xiga. Habkan daaweyntu wuxuu ku habboon yahay alaabta aluminiumka ah ee leh shuruudaha nadaafadda dusha sare ee elektiroonigga, isgaarsiinta, korontada iyo meelaha kale.

Si loo soo koobo, daaweynta dusha sare ee aluminiumku waa in la beddelo dusha sare ee aluminium iyo qalabkeeda aluminiumka iyada oo loo marayo nidaamyo taxane ah iyo habab si loo hagaajiyo sifooyinka dusha sare, kor loogu qaado caabbinta daxalka iyo qurxinta. Habka daaweynta dusha sare ee habboon ayaa loo dooran karaa iyadoo loo eegayo baahiyo gaar ah si loo helo saameynta dusha sare iyo waxqabadka ugu fiican.
