Q:Which kind of glue can bond two pieces of aluminum sheets?
glass sealant
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
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 zinc sheet and aluminum sheet?
Only zinc sheet can react, zinc is amphoteric.
Q:why does aluminum sheet not react with sulfuric acid nut react with hydrochloric acid?
aluminum reacts with hydrochloric acid,generating aluminium chloride which can dissolve in water. but aluminum reacts with sulfuric acid, generating aluminum sulfate which can't dissolve in water and will generate aluminum sulfate, a layer of protective film, preventing aluminum from reacting with sulfuric acid, so there is no significant phenomena.
Q:could magnet attract iron with the seperation of rubber and aluminum sheets?
no problem.
Q:why intact aluminum sheet stop quicker than pectinate one in the magnetic field?
while swinging in the magnetic field, intact aluminum sheets will formulate inner eddy current,that is the annular induced current.eddy current will transform the mechanical energy into heat energy, which makes the aluminum sheet stop quickly.but pectinate aluminum sheet can't formulate intact eddy current, so intact aluminum sheet stop quicker than pectinate one.
Q:what kind of abradant should be used in the deburring of aluminum sheets? How to grind?
we usually use resin grind stone to grind aluminum sheets, Vibration Grinding Mill is also ok.
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 connect copper pipe and aluminum sheet?
it depends on the size and requirement, we can use ultrasonic wave rolling welding to connect copper pipe and aluminum sheet.for example, solar energy radiator-fan contains connection of copper pipe and copper sheet, ultrasonic wave rolling welding equipment is used here.ultrasonic wave welding of metals is suitable for the welding of copper to copper, copper to aluminum and aluminum to aluminum.
