Q:which kind of aluminum sheet could be bended after being etched?
general etching materials include stainless steel and copper.
Q:what's the oxidation method of positive pole on the surface of aluminum sheet?
Do chemical polishing again, oxidation time is about 40 – 90 minutes, after finishing all of these, you can conduct positive pole oxidation, choose sulfuric acid solution in normal situation, pretreatment is very important in the whole process, take stereo as negative pole, firstly, use the solution mixed of carbonate-bicarbonate and detergent to heat and clean its surface, pretreat the aluminum sheet, dyeing according to requirement after oxidation, then remove the oxide film with oxide film removal solution, place aluminum sheet on the positive pole, finally closing it in the boiling water for about 15 minutes.
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:whst should I notice while welding aluminum sheet and aluminum block?
two types of aluminum reach melting points, aluminum block must be preheated when you weld them with small current, you will know how to do it. You can use argon-arc welding back and forth, preheat it with small current.
Q:As for graphite and aluminum sheet, which one has a better thermal conductivity?
Aluminum sheet has a better thermal conductivity, because metal is good conductor of heat, graphite is n't metal.
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: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: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.
