1, Aluminum sheet with a large amount of water for the first time;

2,With a soft cloth to wipe the surface with water diluted detergent gently wipe;

3, Aluminum sheet with a large number of water washing plate, the dirt will be washed away;

4, Check the aluminum sheet, for no clean place with cleaning agent cleaning key;

5, Aluminum sheet with clear water rinse, to be clean.

Note: do not wash the hot plate (temperature above 40 degrees Celsius), because excessive evaporation of water is harmful to the surface paint!

Special need to pay attention to, please select the appropriate detergent, a basic principle is: be sure to use a neutral detergent! Please do not use strong alkaline detergent, such as potassium hydroxide, sodium hydroxide or sodium carbonate, strong acid detergent, detergent and paint dissolution of detergent.

Q:what kind of aluminum sheet is suitable for aluminum alloy double-edged saw?
general horizontal driving sawing and precision sawing.
Q:which kind of abraser should be used for deburring of aluminum sheet?
you can use soft resin grinding stone.
Q:does aluminum sheet has a function of magnetism isolating?
no, it needs ferromagnetic materials.
Q:how to connect copper pipe and aluminum sheet?
welding!
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:Could ring-pull can be transformed as aluminum sheet?
Yes
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 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: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: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.
