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:could aluminum sheet be attracted by magnet?
no, it couldn't.
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.
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: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:why could aluminum pot be repaired by knocking the aluminum sheet into the pot but not being bonded by glue?
the oxidation rate of aluminum's surface is very quick, so we cann't use the method of tin welding, and the cost of argon arc welding is very high,so aluminum pot's repair usually uses riveting. aluminum has low hardness and good ductility, so it can be repaired by tightly knocking, without the bonding of glue. general glue will decomposed in open fire, if we bond pot by glue, the pot after repair won't be able to endure high temperature.
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: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:How could two pieces of aluminium flakes be welded together?
its welding strength is very high. you can use the following methods to weld two pieces of aluminum sheets together: 1, strict deformation control requirement. 3, it can prevent some flux remnant during welding. 3,the welding wire welding of low temperature M51 and M51-F is operated under 179︒C.or they are welded in the situation of being especially thin.4, it can solve the welding of 3 series aluminium alloys and casting, and its welding temperature is 380-400︒C.its advantage is that you don't need any flux during welding. WE53 low temperature aluminium welding wire has a high affinity in welding 7 series aluminium alloys. and Q303 low temperature aluminum welding wire has a high affinity for the welding of 1 series aluminium alloys, die casting or 6 series welding materials.
Q:what’s the difference of activated aluminum and aluminum sheet?
39,the thermal treatment of age hardening aluminum alloy, 40, lanthanum-praseodymium-cerium aluminum alloy and its producing technology, 41,casting method of cool room pack alloy without draft angle, 42, use the anti-corrosion alloy layer to protect the surface of nickel base alloy products, 43,saltless and inoxidizability remelting method of aluminum, aluminum alloy and aluminum waste...
