Q:what kind of aluminum sheet is suitable for aluminum alloy double-edged saw?
general horizontal driving sawing and precision sawing.
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: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:Could induction heating fuenace be packaged with aluminum foil as insulation material?
Aluminum foil can’t be used for heat retaining, it’s unsafe and hasn’t good efficiency. In this case, advice you use refractory cement to knot the coil and connect porcelain tube in the middle. It will Largely reduce the energy consumption produced by heat radiation.
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.
Q:How to polish aluminum sheet to be bright?
you must do some protection work, or you will fail once aluminum contacts air. Aluminum sheet is easy to be oxided and volatilized.
Q:When water continually sprays on the aluminum sheet, how to avoid corrosion of aluminum sheet and keep its water resistance?
aluminum will react with oxygen, generating dense Al2O3 oxide film on the surface, once the pure aluminum is exposed in air, it will react with air, generating oxide film to protect it.
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:what’s the difference of activated aluminum and aluminum sheet?
you can use weak acid ,weak base solvent or steam to clean the oil and dirt on the surface, it's activated aluminum, their difference is that activated aluminum has porous structure oxide film.
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.
