Kev tshem tawm zoo ntawm Oxide zaj duab xis thiab impurities

 

Kev tshem tawm oxide zaj duab xis: Lub ntuj tsim oxide zaj duab xis rau saum npoo ntawm aluminium alloys tuaj yeem cuam tshuam cov txiaj ntsig ntawm kev kho mob tom ntej. Pickling tuaj yeem tshem tawm cov yeeb yaj kiab oxide no kom raug. Piv txwv li, los ntawm kev siv qhov tsim nyog - concentration acid tov (xws li dilute sulfuric acid los yog dilute hydrochloric acid), sulfuric acid (₂₄) reacts nrog aluminium oxide (₂₃) rau ntawm qhov chaw ntawm aluminium alloy los tsim aluminium sulfate (₂₄₃) thiab dej (₂). Qhov sib npaug ntawm cov tshuaj tiv thaiv yog ₂₃₂₄₂₄₃₂. Los ntawm cov tshuaj tiv thaiv no, cov oxide zaj duab xis yog yaj, nthuav tawm cov hlau tshiab rau ntawm qhov chaw ntawm aluminium alloy thiab muab lub hauv paus zoo rau kev kho mob tom ntej xws li anodizing thiab electroplating.

 

Kev tshem tawm impurity: Thaum lub sij hawm ua thiab khaws cia ntawm aluminium alloys, qhov saum npoo yuav kis tau nrog ntau yam impurities, xws li cov khib nyiab hlau, plua plav, thiab qee qhov sib xyaw ua ke uas ua rau lub sijhawm ua haujlwm. Cov txheej txheem pickling tuaj yeem yaj cov impurities zoo. Piv txwv li, ib co intermetallic tebchaw (xws li txhuas - tooj liab compound ₂) yuav raug tshuaj lom neeg cov tshuaj tiv thaiv nyob rau hauv cov kua qaub, ua rau cov impurities cais tawm ntawm qhov chaw, yog li xyuas kom meej lub purity ntawm aluminium alloy nto thiab pab txhim kho qhov zoo. ntawm tom qab - tsim cov yeeb yaj kiab tiv thaiv lossis txheej txheej.

 

Txhim kho qhov dej num

 

Txhim khu kev ua haujlwm: Tom qab cov oxide zaj duab xis raug tshem tawm los ntawm pickling, cov hlau atoms ntawm qhov chaw ntawm aluminium alloy yog ncaj qha raug. Cov hlau atoms tshiab no muaj kev ua haujlwm siab dua thiab tuaj yeem koom nrog ntau dua hauv cov tshuaj tiv thaiv tom ntej. Piv txwv li, thaum lub sij hawm anodizing, lub active aluminium alloy nto yog feem ntau yuav hnov ​​​​mob nrog cov ions hauv electrolyte. Noj cov sulfuric acid electrolyte ua piv txwv, aluminium atoms () ntawm lub anode yuav plam electrons sai dua thiab hnov ​​​​mob nrog dej los tsim aluminium oxide (₂₃). Qhov sib npaug ntawm cov tshuaj tiv thaiv yog ₂⁻₂₃⁺, yog li ua rau cov yeeb yaj kiab oxide generated zoo ib yam thiab ntom.

 

Muaj txiaj ntsig zoo rau ntau yam txheej txheem kho deg: Xws li ib tug heev - nquag nto tsis yog tsuas yog pab tau rau anodizing, tab sis kuj pab tau heev rau lwm yam tshuaj hloov dua siab tshiab kev kho mob (xws li chromating thiab phosphating) thiab txheej txheej txheem. Hauv kev kho tshuaj hloov dua siab tshiab, qhov ua haujlwm siab heev tuaj yeem cuam tshuam zoo dua nrog cov khoom siv hauv cov kua tshuaj los tsim cov yeeb yaj kiab hloov dua siab tshiab nrog cov khoom zoo dua. Piv txwv li, thaum kho chromating, cov active aluminium atoms nyob rau saum npoo yog feem ntau yuav hnov ​​​​mob nrog chromate ions (₄²⁻) hauv cov tshuaj chromate los tsim cov chromate hloov dua siab tshiab zaj duab xis nrog zoo corrosion kuj, muab kev tiv thaiv zoo dua rau aluminium alloy.
