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 does 10% sulfuric acid not react with aluminum sheet?
10% sulfuric acid has a high concentration and will be passivated and formulate a layer of oxide film after reacting with aluminum,and the reaction will stop after seperating sulfuric acid and aluminum. there is a layer of Al2O3 oxide film on the surface of aluminum, so it's hard for sulfuric acid to break the oxide film and react with aluminum.
Q:what's the difference between aluminum sheet detergent and central air-condition detergent?
Central air condition cleaning includes air-cooled condenser cleaning and water-cooling condenser cleaning, if it’s air-cooled condenser cleaning, you can use aluminum sheet detergent.
Q:Which kind of glue can bond two pieces of aluminum sheets?
you can use jellied universal glue, don't use the liquid one, because it's only suitable for plastics or materials easy for erosion.
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:what's the temperature tolerance of aluminum sheets?
aluminum is a kind of silver white metal,melting point:660.4℃, boiling point: 2467℃,density: 2.70 g/cm³,very light, about 1/4 of iron's density.it has low hardness and good ductility, which makes it suitable for being pulled into threadlets or pressed into aluminum foils, and the later is usually used for packaging candy and cigarette. it has good electrical and temperature conductivity. it's used for the manufacture of electric wire and cable in electric power industry, and for the manufacture of cooker in daily life.combined with the magnesium , copper,zinc,tin,manganese,chromium,zirconium,silicon and other elments,it can formulate various alloys that is broadly used for the manufacture of airplane,car,ship, materials of daily living equipment and the doors and windows of construction industry.aluminum is one of the best reflectors of heat and light, so it is used as thermal insulation material and the manufacture of reflecting mirror in the reflecting telescope.
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: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:how to process 0.3mm hole on aluminum material?
It's bored by drill.
Q:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
