Q:how to avoid oxidation of aluminum sheet after wire drawing?
leave it alone after wire drawing!aluminum sheet will formulate a layer of dense oxide film. So you don't need to worry about it! Don't often polish the aluminum wire, or they will be more and more slimsy, the oxide film is used for avoiding reoxidation.
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: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:what's the size of gap while pressing 6mm aluminum sheet?
unilaterial gap is 0.1-0.15mm, and you can change the gap according to cutting effect.
Q:How to clean the engine oil and kerosene on the surface of aluminum sheet?
You can clean it with detergent of carburetor, and buy it in auto accessories shop.
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:Which kind of glue is best for bonding wood and aluminum sheet together?
You can use 502 adhesive.
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:has aluminum sheet reacted with concentrated sulfuric acid?
it can be regarded as no reaction, concentrated sulfuric acid will make aluminum's surface inactivation,and produce a layer of dense aluminium oxide film which will prevent further reaction.
Q:is general aluminum sheet fire-proof?
general aluminum sheet is less fireproof than tinfoil.
