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:after putting aluminum sheet into the area between magnet and iron products, could magnet attract iron again?
magnet can attract iron if the aluminum sheet isn't too thick. Because aluminum can't cut off magnetic line of force, unless aluminum sheet's thickness surpass the range of magnetic attraction.
Q:How to press multilayer aluminum sheets (aluminum sheet's thickness: 0.2mm) together and keep them inseperate after pressing?
resistance welding usually overlays two pieces together and presses them, heating them to melting state through current, you can try multiple sheets.
Q:what will happen when aluminum sheet is put into copper chloride solution?
the chemical equation of the reaction, 2Al+3CuCl2=2AlCl3+3Cu, the phenomena when aluminum sheet is put into copper chloride solution: there is red solid generating on the surface of aluminum sheet.
Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
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: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: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:what’s the difference of activated aluminum and aluminum sheet?
contain more water and activated
Q:does aluminum sheet need to conduct ROHS detection?it's metel material, how much detections should it conduct for ROHS detection?
it needs 4 CTI detections for ROHS.
