- Q:why can aluminum sheet after oxide film removal react quicker with hydrochloric acid?
- the reason is very simple, the original aluminum sheet has a layer of dense oxide film AI2O3, which has prevented the inner aluminum sheet from reacting with hydrochloric acid. but after oxide film removal,
aluminum sheet will directly contact hydrochloric acid, generating H2.
- Q:How to press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
- resistance welding usually overlays two pieces together and presses them, heating them to melting state through current, you can try multiple sheets.
- Q:why can't aluminum sheet burn after polishing?
- because aluminum will rapidly formulate dense oxide film once being exposed in air, oxide film will generate after polishing, it can't burn.
- Q:How to distinguish aluminum sheet from magnesium sheet?
- magnesium sheet will react with alkali.
- Q:who knows the ceiling technology of aluminum sheet?
- Different materials usually have difference in construction technology. The detailed ceiling construction technology process of aluminum buckle plate:1, snapping line: according to the elevation horizontal line of floor, designed elevation, surrounding ceiling elevation horizontal line, you can find the central point of your room. Then alone the ceiling’s elevation horizontal line, take the central point of your room as focus, you can draw the grading line of keel. 2, install main keel boom: after ensuring the ceiling’s elevation horizontal line and keel’s location line, you can measure the elevation of the below ending of boom, and install the boom processed before. You can use expansion bolt to fix the boom on ceiling. Choose round steel as boom, control the gap of hanging bar under the range of 1200mm.3, install main keel: choose C38 light steel keel as main keel, control the gap under 1200mm. connect it with fitting and boom matched with main keel while installing. 4, install side keel: fix 25×25mm coated keel on the surrounding wall with cement nail according to net height of ceiling, control the cement nail’s gap under 300mm. 5, install sub keel: install the sub keel matched with aluminum buckle plate according to the size of aluminum buckle plate, hang the sub keel on main keel through hanger. When the sub keel needs to be prolonged by several keel, use the adapting piece of sub keel, connect the two ends and fix them after straightening at the same time of hanging the sub keel.
- Q:which is the best bonding method for aluminum sheet and plastic?
- smear glue, there is a glue special for the bonding of plastic and steel materials.
- Q:why is copper sheet but not aluminum sheet that becomes the negative pole after putting copper sheet and aluminum sheet connected with wire into concentrated nitric acid?
- According to metal reactivity series order table, aluminum has a better metallicity, but it will be passivated soon after contacting concentrated sulfuric acid, and won’t react again. But copper and concentrated sulfuric acid can react continually. So aluminum sheet becomes the positive pole after passivation.
- Q:What are the colors of iron sheet and aluminum sheet?
- both of them are silver white.
- Q:what’s the difference of activated aluminum and aluminum sheet?
- contain more water and activated
- Q:which kind of enterprises are aluminium sheet circles used in?
- user use cold squezz method to transform the aluminum sheet circle into various standard capacitor shell, aluminium collapsible tube shell, which are broadly used in electron industry, daily chemical industry, medicine, education and automobile products,electrical appliance, heat preservation, machine manufacturing, automobile,spaceflight,military industry,mould, construction, printing and other industries.
