Nyob rau hauv kev cai txhuas fabrication, cov khoom yuav ua tau txhuas ntawv hlau thiab txhuas alloy profiles nrog rau oxidized profiles, electrophoretic profiles, hmoov txau profiles. Rau kev kho deg, feem ntau siv yog hmoov txheej thiab anodize.
Cia wb mus saib qhov txawv ntawm ob.
Aluminium Anodization Thiab Sandblasting
Oxidation yog siv lub substrate ua ib qho anode thiab muab tso rau hauv ib qho electrolyte rau electrolysis los ua ib tug tiv thaiv oxide zaj duab xis nyob rau saum npoo ntawm substrate.
Oxidation txheej txheem: substrate → loading thiab dai → degreasing → ntxuav → alkaline etching → ntxuav → neutralization → ntxuav → anodizing → ntxuav → electrolytic coloring → ntxuav → sealing → ntxuav → ziab → unloading → tshuaj xyuas → ntim.
Aluminium khoom nrog anodise muaj cov hauv qab no nta:
1. Nws muaj zog hnav tsis kam, huab cua tsis kam thiab corrosion kuj.
2. Ntau yam xim tuaj yeem tsim rau saum npoo ntawm substrate kom haum koj cov kev xav tau.
3. Muaj zog hardness, haum rau kev tsim khoom ntawm ntau yam kev tsim kho thiab cov khoom siv
Cov khoom siv oxidation muaj xws li: oxidized tiaj dawb khoom, oxidized colorant, oxidized frosted dawb khoom, oxidized frosted colorant.
Hmoov txheej Aluminium
Hmoov txheej txhuas, nws cov txheej txheem yog txheej txheem suav nrog chroming, hmoov txau, ci thiab lwm yam. Tom qab cov hmoov txheej, cov xim zaj duab xis yuav tsum tau ci thiab kho kom tsim tau ib qho tawv thiab tawv xim xim zaj duab xis rau ntawm tus thawj aluminium nto. Nws tsim ib hom kev tiv thaiv rau cov khoom siv txhuas, thiab nws qhov adhesion, uniformity thiab huab cua tsis kam ua rau cov xim ntawm cov khoom siv aluminium smoother thiab ntau yam, thiab ua rau cov khoom txhuas tiv taus acid.
Lub hauv paus ntsiab lus yog: nws yog ua los ntawm thermosetting saturated polyester hmoov, tom qab chromizing kev kho mob, cov xim yog txuas rau saum npoo ntawm cov khoom los ntawm kev txau thiab ziab ntawm 200 degree.
Cov txheej txheem hmoov txheej: xaiv → tshuab ntxhua khaub ncaws → tshuaj xyuas → kev npaj → dej ntxuav → degreasing thiab degreasing → dej ntxuav → dej huv → chroming → dej ntxuav → mos mos ntxuav → dej → ziab → kuaj → tshem tawm thiab tawm → tshuaj xyuas → Muab tso rau hauv txee → soot tshuab → hmoov txau → tshuaj xyuas → kho → tawm ntawm lub txee → tshuaj xyuas → ntim → cia.
