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: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:how much should the current be adjusted when I use pulse aluminum welding machine to weld 0.7 aluminum sheet?
60-70A current is enough for 0.7 aluminum sheet,the key poiny is that the thin sheet should be bonded with iron sheet or other assistant cooling device when you weld it, or it will be burned through.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
Q:who knows the ceiling technology of aluminum sheet?
Different materials usually have difference in construction technology. The detailed ceiling construction technology process of aluminum buckle plate:1, snapping line: according to the elevation horizontal line of floor, designed elevation, surrounding ceiling elevation horizontal line, you can find the central point of your room. Then alone the ceiling’s elevation horizontal line, take the central point of your room as focus, you can draw the grading line of keel. 2, install main keel boom: after ensuring the ceiling’s elevation horizontal line and keel’s location line, you can measure the elevation of the below ending of boom, and install the boom processed before. You can use expansion bolt to fix the boom on ceiling. Choose round steel as boom, control the gap of hanging bar under the range of 1200mm.3, install main keel: choose C38 light steel keel as main keel, control the gap under 1200mm. connect it with fitting and boom matched with main keel while installing. 4, install side keel: fix 25×25mm coated keel on the surrounding wall with cement nail according to net height of ceiling, control the cement nail’s gap under 300mm. 5, install sub keel: install the sub keel matched with aluminum buckle plate according to the size of aluminum buckle plate, hang the sub keel on main keel through hanger. When the sub keel needs to be prolonged by several keel, use the adapting piece of sub keel, connect the two ends and fix them after straightening at the same time of hanging the sub keel.
Q:could magnet attract iron with the seperation of rubber and aluminum sheets?
It does in theory, but rubber and aluminum sheets can’t be too thick, larger magnetic force of magnet will be better.
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:as for heating coil and aluminum sheet, which one is better for heating?
Both of them have advantage. It depends on the new product type it’s applied. Heating coil: it’s applied in some products with high temperature and large heat release, such as oven and other types.
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 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.
