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: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 press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
resistance welding is a welding method that pressing the materials to be welded in an area between two poles and switching on current. the current will go through the contact surface and agjacent area, producing resistance heat effect which will heatthe materials into melting or plastic state and make the materials be welded together.
Q:Which kind of glue can bond two pieces of aluminum sheets?
you can use tin welding.
Q:Could ring-pull can be transformed as aluminum sheet?
Yes, but the ring-pull cans contains fewer aluminum.
Q:How to solve the loose bonding of aluminum sheet and silica gel?
Bonding silicone rubber needs surface treatment, after using silicone rubber surface treating agent of Kuer , you can bond them with 4211 adhesive.
Q:Which kind of glue is best for bonding wood and aluminum sheet together?
You can use 502 adhesive.
Q:who knows the ceiling technology of aluminum sheet?
Construction technology of ceiling aluminum sheet: (1) firstly check keel’s quality, the straight shape and uniformly forced state of boom, control the keel’s gap within 500mm, reduce the gap according to design requirement under humid environment. The lower surface of keel is smooth without a sense of bearing down, main device is closely connected with accessories, it can be bound after being confirmed qualified.(2) we should break the board along the cutting line and ensure the margin of cutting board straight and square without any chipping or arris defect. (3) while placing and fixing the board, we can place edge of aluminum-plastic panel(encapsulated edge) in the vertical direction of supporting keel, there is a phenomena of hanging. Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. You can start from a plate angle or middle position, and don’t place them at the same time. Slab joint should be straight and in the same width, without break joint. (4) in the process of joint, Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. And the butt joint should be stagger, the butt joint can’t be connected on the same keel. When you use doubling plate, the joints of the second layer board and the first layer board can’t be connected with the same keel, double-deck gypsum board should be staggered joints.
Q:Could copper wire be welded with aluminum sheet?
Copper wire could be welded with aluminum sheet, and it needs to use low temperature welding method, if copper wire is in the unit of millimeter and aluminum sheet is also in the unit below 1 mm, you can use electric soldering iron to heat it as hybrid welding and choose low temperature welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. As for the large aluminum sheet, you can take liquefied gas multihole lance as heat source, then choose the same low temperature materials as welding materials, you can use WEWELDING M51 welding wire and M51-F flux to complete welding. Welding fundamentals of these two welding methods: both of them are use heatable heat source to heat the matrix to 179 degree, the melting point of WEWELDING M51, then use matrix’s heat conduction to melt welding wire, completing welding. The process of melting welding wire is the process of smearing the welding wire with flux into welding area, melting welding wire completely depends on matrix’s heat conduction.
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.
