Q:What are the colors of iron sheet and aluminum sheet?
both of them are silver white.
Q:why does aluminum sheet not react with sulfuric acid nut react with hydrochloric acid?
aluminum reacts with hydrochloric acid,generating aluminium chloride which can dissolve in water. but aluminum reacts with sulfuric acid, generating aluminum sulfate which can't dissolve in water and will generate aluminum sulfate, a layer of protective film, preventing aluminum from reacting with sulfuric acid, so there is no significant phenomena.
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:As for graphite and aluminum sheet, which one has a better thermal conductivity?
aluminum sheet
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: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:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
the surface should be kept clean to avoid the influence of oil contamination.
Q:does aluminum sheet has a function of magnetism isolating?
yes.
Q:what's the difference between the knocking voice of aluminum sheet and stainless steel?
The voice of aluminum sheet is toneless, and the voice of stanless steel is more crisp.
Q:why does the bubble apear a few minutes later after putting aluminum sheet into dilute sulphuric acid?
it firstly etches off the oxide on the surface of aluminum, and then reacts with aluminum, generating bubble.
