Q:as for heating coil and aluminum sheet, which one is better for heating?
Heating coil has a short lifetime, and aluminum sheet for heating can be used for a long time. Stainless steel heating tube is embedded into aluminum sheet for heating, because the heating coil isn’t exposed, it can be used for a long time.
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:Could two pieces of aluminum sheets be welded together?
or you can use file to rub back and forth, and it needs lots of practices or you can't weld the sheets.because aluminum sheet cann't be tightly welded to tin, it's hard to weld two pieces of aluminum sheets by common welding methods.it's hard, the aluminum sheets are oxidized soon after polished by abrasive paper.and you need to cover the new polished area with soldering paste and learn some operating skills.owing to aluminum sheets' high oxidized speed, you need to wipe the aluminum sheets with soldering paste and soldering tin and rub them with large power soldering iron, then the aluminum sheets will be tightly welded to tin.so two pieces of aluminum sheets could be welded together.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
hardware
Q:Could induction heating fuenace be packaged with aluminum foil as insulation material?
You have thought about it carefully, you can't use aluminum foil.
Q:does aluminum sheet need to conduct ROHS detection?it's metel material, how much detections should it conduct for ROHS detection?
generally, all things in Europe needs ROSH EU's requirement, mainly detect the plumbum. ROSH detection is conducted by third party institution, and its report is also provided by the third party.
Q:How to polish aluminum sheet to be bright?
as for polishing, fine grit sandpaper can't polish it into a mirror,but laser cutting can do it.
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: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: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.
