- 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 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.
- Q:how to produce aluminium sheet circle?
- As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
- Q:which is the best bonding method for aluminum sheet and plastic?
- smear glue, there is a glue special for the bonding of plastic and steel materials.
- Q:why does the hardness of 2024 aluminum sheet not increase but decrease after thermal treatment?
- The hardness of 2024 aluminum sheet will decrease after thermal treatment(solution treatment), and it will increase after aging treatment.
- 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: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:can the oxide film on the surface of aluminum sheet prevent the erosion of acid liquid? Why?
- yes, acid can react with aluminum oxide , generating salt and water, but its anti-corrosion will be stronger if oxide film on the surface is enough dense.
- Q:is aluminum foil spacer poisonous after heating?
- It’s a kind of thermoprint material made by pressing the aluminum into sheet, and owing to its similar thermoprint effect to silver foil, so it’s called fake silver foil. Aluminum has soft texture, good ductility, and is silver white, if we use sodium silicate to paste the sheet after pressing on the offset paper, making aluminum foil, the foil can be printed. But aluminum foil is easy to be oxidized and darkens, rubbing and touching will make it darken, so it doesn’t suit for the thermoprint of books’ cover that needs to be preserved for a long time.
- Q:what kind of aluminum sheet is suitable for aluminum alloy double-edged saw?
- saw web size depends on the thickness and height of sectional material,equipment compatibility and permitted installed saw web size .
