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:As for graphite and aluminum sheet, which one has a better thermal conductivity?
Aluminum sheet has a better thermal conductivity, because metal is good conductor of heat, graphite is n't metal.
Q:what’s the difference of activated aluminum and aluminum sheet?
39,the thermal treatment of age hardening aluminum alloy, 40, lanthanum-praseodymium-cerium aluminum alloy and its producing technology, 41,casting method of cool room pack alloy without draft angle, 42, use the anti-corrosion alloy layer to protect the surface of nickel base alloy products, 43,saltless and inoxidizability remelting method of aluminum, aluminum alloy and aluminum waste...
Q:which kind of material won't influence magnet attracting iron nail? Does copper sheet or aluminum sheet influence it?
Copper coil will impede magnetic penetration. People separate the magnet from the workpiece of machine tool to avoid magnetic short circuit and attraction loss, making magnetic line of force go through the workpiece. An opening copper bush is added into the iron core of magnetic closing coil or opening solenoid to avoid the iron core being attracted on the external iron piece and stop operation. The opening is for avoiding eddy formulation and short circuit, iron core in copper bush is the ruled magnetic circuit.
Q:could aluminum sheet be attracted by magnet?
no, it couldn't.
Q:which kind of abraser should be used for deburring of aluminum sheet?
as for the polishing of aluminum material, we usually nylon wheel and similar products.
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
Q:is aluminum foil spacer poisonous after heating?
many baked food will use aluminum foil.
