- Q:why does 10% sulfuric acid not react with aluminum sheet?
- 10% sulfuric acid has a high concentration and will be passivated and formulate a layer of oxide film after reacting with aluminum,and the reaction will stop after seperating sulfuric acid
and aluminum. there is a layer of Al2O3 oxide film on the surface of aluminum, so it's hard for sulfuric acid to break the oxide film and react with aluminum.
- Q:what's the difference between aluminum sheet detergent and central air-condition detergent?
- Central air condition cleaning includes air-cooled condenser cleaning and water-cooling condenser cleaning, if it’s air-cooled condenser cleaning, you can use aluminum sheet detergent.
- 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 are the colors of iron sheet and aluminum sheet?
- Q:When water continually sprays on the aluminum sheet, how to avoid corrosion of aluminum sheet and keep its water resistance?
- Don’t worry about it, after aluminum contacts water or air, a layer of oxide film will generate on its surface to separate aluminum from the water or air and protect it, so it won’t be erosive.
- Q:which kind of abraser should be used for deburring of aluminum sheet?
- you can use soft resin grinding stone.
- 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 difference between zinc sheet and aluminum sheet?
- Only zinc sheet can react, zinc is amphoteric.
- 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 make aluminum products bright? How to polish or clean the products punch formed by 0.3mm aluminum sheet?
- you can try to grind it with magnetic grinder.
