anodizing tuag cam khwb cia txhuas yog cov txheej txheem ntawm kev tsim cov txhuas oxide zaj duab xis rau ntawm qhov chaw ntawm txhuas los yog txhuas alloy khoom los ntawm immersing lawv nyob rau hauv ib tug electrolyte tov thiab siv ib tug hluav taws xob tam sim no. Qhov kev kho mob no ua rau cov yeeb yaj kiab oxide uas txhim kho corrosion kuj, hnav tsis kam, thiab pom kev pom ntawm cov khoom siv txhuas tuag-casting.
txoj cai
Thaum lub sij hawm anodic oxidation txheej txheem, cov ntxeem tau oxide zaj duab xis tsim nyob rau saum npoo ntawm txhuas muaj peev xwm adsorb dyes, uas yuav siv tau rau xim txheej zaj duab xis. Txoj kab uas hla ntawm anodized pores feem ntau yog nyob nruab nrab ntawm {{0}}.01-0.01um, thiab dyes nrog ib txoj kab uas hla ntawm 0. . Thaum cov xim yog adsorbed rau saum npoo ntawm qhov pores thiab diffuses rau hauv lawv, nws accumulates thiab tsim ionic bonds nrog txhuas oxide, uas ua rau hydrogen bonds uas muab xim rau cov zaj duab xis txheej. Cov dyes yog tsau nyob rau hauv lub pores tom qab sealing.
xim
Cov txheej txheem anodizing tuaj yeem ua rau ntau yam xim, suav nrog dub, nyiaj, thiab liab. Cov xim uas xav tau tuaj yeem xaiv tau thaum lub sijhawm txheej txheem anodizing kom ua tiav qhov xav tau zoo rau kev lag luam txhuas profiles.
Anodic oxidation sealing txheej txheem ntawm txhuas profile
High-temperature sealing dej yog ib txoj hauv kev zoo rau sealing anodized aluminium oxide zaj duab xis. Txoj kev no siv cov tshuaj tiv thaiv hydration ntawm aluminium oxide zaj duab xis thiab dej los hloov cov amorphous zaj duab xis rau hauv hydrated crystalline zaj duab xis. Lwm txoj kev yog inorganic ntsev sealing, uas tuaj yeem txhim kho qhov ceev ntawm cov xim dyes. Ib txoj kev sib khi cov organic cuam tshuam nrog rau cov txhuas oxide zaj duab xis hauv cov roj, xim, lossis lwm hom txheej.
Anodizing xim txheej txheem
Muaj ntau txoj hauv kev rau xim txheej anodized zaj duab xis, suav nrog kev txhim kho ntuj tsim thaum lub sijhawm electrolysis, ntxiv cov ntsev ntsev lossis lwm cov kua qaub rau hauv da dej, electrolytic xim siv Ni, Sn, lossis Ni-Sn tov ntsev, thiab dyeing txoj kev. Lub porosity ntawm oxide zaj duab xis yog qhov tseem ceeb thaum siv txoj kev dyeing vim tias cov phab ntsa sab hauv ntawm lub qhov yuav tsum muaj peev xwm adsorption. Cov yeeb yaj kiab sulfuric acid oxide feem ntau yog siv vim nws qhov pores kuj loj, muab cov yeeb yaj kiab ntshiab dua.
Feem ntau, cov txheej txheem ntawmanodizing tuag-cast aluminiumKev tswj hwm qhov tseem ceeb xws li voltage, tam sim no ceev, da dej muaj pes tsawg leeg, thiab concentration los ua ib tug ntxeem tau zaj duab xis ntawm aluminium nto, ces electrodeposit hlau los yog adsorb dye nyob rau hauv cov pores, thiab ces nws yog kaw. Qhov tshwm sim corrosion-resistant, hnav-resistant, thiab zoo nkauj pleasing tiv thaiv txheej txhim khu lub durability thiab zoo nkauj ntawm txhuas tuag-casting khoom thiab txhuas alloy tuag-casting khoom.
