Q:what's the difference between the knocking voice of aluminum sheet and stainless steel?
The voice of aluminum sheet is toneless, and the voice of stanless steel is more crisp.
Q:what kind of abradant should be used in the deburring of aluminum sheets? How to grind?
you can use deburring brush,grinding fluid,abrasive powder and other consumables.
Q:why does the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
Q:How to distinguish aluminum sheet from magnesium sheet?
put them into NaOH, the one generating bubble is aluminum sheet, because aluminum sheet can react with it, generating hydrogen. Or light them in the air, the burning one is magnesium sheet.
Q:How to solve the loose bonding of aluminum sheet and silica gel?
you can use YH-840 to bond silica gel and aluminum sheet in small area, and it’s hard to tear and will have an effect of destruction and melting, transparent and environmental.
Q:How could two pieces of aluminium flakes be welded together?
You can use argon arc welding, connect the positive pole with alternating current,aluminum wire as the welding wire.
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: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's the difference between zinc sheet and aluminum sheet?
Only zinc sheet can react, zinc is amphoteric.
