- Q:why can aluminum sheet after oxide film removal react quicker with hydrochloric acid?
- the reason is very simple, the original aluminum sheet has a layer of dense oxide film AI2O3, which has prevented the inner aluminum sheet from reacting with hydrochloric acid. but after oxide film removal,
aluminum sheet will directly contact hydrochloric acid, generating H2.
- Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
- it's metal and belongs to hardware
- Q:Which kind of glue is best for bonding aluminum sheets?
- Q:Which kind of glue can bond hard shell plastic and iron sheet or aluminum sheet?
- You can use 502, Alteco and other instant glue to bond plastic and metal, chloroprene rubber adhesive or glass cement are also ok.
- 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:how to produce aluminium sheet circle?
- As for the process, you can use punch.. as for professional machines, for example, stationary press in open type, mechanical press/ single-point press. The material you say is neither big nor small, blanking…(cutting them into sheet circle you want) you can add an uncoiling if it’s coil stock: open-type inclinable press, four-point press,ect. It’s not certainly accurate) punch, oil press, double , four-column hydraulic (oil) press,etc. it needs about 315T,(estimated value, closed type single, blank material cutting (cutting into square ) 2, it contains sheet metal forming technology, crank press: 1: straight side two : 1, but the components you said is simple, only two steps.
- 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:How to distinguish aluminum sheet from magnesium sheet?
- put two sheets into excess NaOH. The one that reacts with NaOH, generating sediment, is magnesium sheet,(sediment, but Al(OH)3 is amphoteric:Mg(OH)2) another one without sediment is aluminum sheet(in fact, there is sediment Al(OH)3, but it will react with alkali,)
- Q:how to distinguish the physical property of copper sheet from the one of aluminum sheet?
- physical property: copper sheet: golden, heavy, aluminum sheet: white, light.
- Q:how to find 0.6mm waste strake of aluminum sheet?
- ask door and window maker for some strake.
