Metals used for shipbuilding
In recent years, lub teeb ntawm lub nkoj hulls tau tsim sai heev, thiab kev lag luam shipbuilding tau txuas ntxiv txhim kho, yog li cov ntaub ntawv raw rau kev tsim nkoj tau dhau los ua qhov tseem ceeb. Ntawm lawv, aluminium alloy yog dav siv, thiab cov ntawv txhuas txhuas tau dhau los ua qhov tseem ceeb tshwj xeeb. Many people don't understand, can't ships use steel? Tam sim no ntau lub lag luam siv hlau. That's be ...
Introduction of black aluminum sheet
Black aluminum sheet is an aluminum sheet with a black coating on the surface, which is usually obtained by oxidation technology or other special processes. It is widely used in various industries due to its high strength, light weight, corrosion kuj thiab zoo nkauj tsos. The black surface is usually achieved by anodizing, powder coating or painting, which can furt ...
Dab tsi yog qhov tshwj xeeb ntawm alu foil rau blister ntim tshuab?
Alu ntawv ci siv nyob rau hauv blister ntim tshuab, tshwj xeeb tshaj yog rau cov kws kho mob, yuav tsum ua kom tau raws li cov kev qhia tshwj xeeb kom muaj kev tiv thaiv zoo, processability thiab ua raws li cov qauv kev cai. Cov specifications ntawm alu ntawv ci siv nyob rau hauv blister ntim tshuab yog nyob ntawm seb tus qauv ntawm lub tshuab ntim khoom., hom ntim khoom a ...
Lub luag haujlwm hnyav aluminium ntawv ci yog tuab thiab ruaj khov dua li cov ntawv txhuas txhuas, tsim los tswj kev ua noj ua haus thiab ntim cov dej num.Qhov tseem ceeb tshaj qhov sib txawv ntawm cov ntawv txhuas tsis tu ncua thiab hnyav txhuas ntawv ci yog nws cov tuab.. Lub luag haujlwm hnyav aluminium ntawv ci yog feem ntau 0.024 mm (24 microns) rau 0.032 mm (32 microns) tuab, ua rau nws muaj zog dua li niaj zaus aluminium ntawv ci, uas feem ntau nyob ib ncig ntawm 0.016 mm ...
Aluminium phaj ntawm anode yog oxidized, thiab ib txheej nyias ntawm txhuas oxide yog tsim rau ntawm qhov chaw nrog ib tug tuab ntawm 5 rau 20 microns, thiab cov yeeb yaj kiab nyuaj anodized tuaj yeem ncav cuag 60 rau 200 microns. Lub anodized aluminium phaj txhim kho nws cov hardness thiab hnav tsis kam, mus txog 250-500 kg/mm2, muaj cua sov zoo heev, cov zaj duab xis nyuaj anodized muaj qhov melting point txog 2320K, rwb thaiv tsev zoo heev, thiab tawg ...
Surface pretreatment
No matter what method is used to process aluminum materials and products, there will be dirt and defects on the surface to varying degrees, such as dust, metal oxides (natural or aluminum oxide films formed at high temperatures), residual oil, asphalt marks, artificial Carrying mudra (the main components are fatty acids and nitrogenous
1. Oxalic acid anodizing
Most of the factors that affe ...
