Aluminium Alloy Surface Daaweynta: 7 Taxane Aluminium Hard Anodizing

1. Dulmarka Habraaca

Anodizing Hard waxay isticmaashaa korantada u dhiganta ee daawaha (sida sulfuric acid, chromic acid, oxalic acid, iwm.) sida anode-ka, oo waxay ku qabataa korantada xaalado gaar ah oo hadda la dabaqay. Dhumucda filimka anodized adag waa 25-150um. Filimada adag ee anodized ee dhumucdiisuna tahay filim ka yar 25um ayaa inta badan loo isticmaalaa qaybo ay ka mid yihiin furayaasha iligga iyo wareegyada. Dhumucda filimada anodized ee ugu adag ayaa loo baahan yahay inay noqdaan 50-80um. Xiro u adkaysta ama dhumucda filimka anodized ee dahaarka waa qiyaastii 50um. Marka la eego shuruudaha nidaamka gaarka ah, waxaa sidoo kale loo baahan yahay in la soo saaro filimo adag oo anodized ah oo dhumucdiisu ka badan tahay 125um. Si kastaba ha ahaatee, waa in la ogaadaa in dhumucda filimka anodized, hoos u dhigista microhardness ee lakabka sare ayaa noqon doona, iyo dusha sare ee lakabka filimka ayaa kordhin doona.

2. Tilmaamaha habka

1) Adkaanshaha dusha sare ee aluminium aluminium ka dib markii ay adag tahay anodizing waxay gaari kartaa ilaa HV500;

2) Dhumucda filimka anodic oxide: 25-150 microns;

3) Adhesion xoog leh, marka loo eego sifooyinka anodizing ee ay soo saarto anodizing adag: 50% filimka anodizing ee la soo saaray ayaa gudaha u galaya aluminium aluminium ah, iyo 50% waxay u hoggaansamaan dusha sare ee aluminium aluminium (koritaanka laba jiho);

4) Dahaarka wanaagsan: danab burburku wuxuu gaari karaa 2000V;

5) Iska caabbinta xirashada wanaagsan: Alloysiyada aluminiumka leh oo leh maaddo naxaas ah oo ka yar 2%, index xirashada ugu badan waa 3.5mg / 1000 rpm. Tilmaanta xidhashada ee dhammaan alliyada kale waa in aanay ka badnayn 1.5mg/1000 rpm.

6) Aan sun ahayn oo aan waxyeello u geysan jidhka bini'aadamka. Habka elektaroonigga ah ee daaweynta filimka anodizing ee loo isticmaalo wax soo saarka waa mid aan dhib lahayn, sidaas darteed shuruudaha ilaalinta deegaanka ee farsamaynta mashiinnada warshadaha badan, alaabooyinka qaarkood waxay isticmaalaan aluminium aluminium adag oo adag halkii ay ka ahaan lahaayeen birta, buufinta dhaqameed, dhejinta chromium adag iyo hababka kale.

3. Goobaha codsiga

Anodizing adag ayaa inta badan ku habboon meelaha u baahan caabbinta xidhashada sare, iska caabinta kulaylka, iyo sifooyinka dahaarka wanaagsan ee qaybaha aluminium iyo aluminium aluminium. Sida dhululubada kala duwan, pistons, valves, liners cylinders, bearings, qaybaha xamuulka diyaaradaha, ulo janjeera iyo tareenada hagaha, qalabka Haydarooliga, impellers uumiga, mashiinada flatbed raaxo leh, marsho iyo baffers, iwm electroplating dhaqameed ee chromium adag ayaa sifooyinka hoose kharashka, laakiin cilladda filimkani waa marka dhumucda filimku weyn yahay, waxay saamaysaa dulqaadka xoogga daalka farsamada ee aluminium iyo aluminium aluminium.
