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:why can't aluminum sheet burn after polishing?
because aluminum will rapidly formulate dense oxide film once being exposed in air, oxide film will generate after polishing, it can't burn.
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 clean the aluminium oxide on the surface of aluminum? What kind of materials should we use to clean the thin aluminum sheet, and what's the concentration?
You can sprinkle the mix of Alkaline water,vinegar,washing powder and liquid detergent on the surface. And after a period of time, rub it with soft silk, after it being dry,sprinkle again and rub until it's clean.
Q:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
no, but I'm not certain.
Q:As for graphite and aluminum sheet, which one has a better thermal conductivity?
Aluminum sheet has a better thermal conductivity, because metal is good conductor of heat, graphite is n't metal.
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:what's the temperature tolerance of aluminum sheets?
aluminum is a kind of silver white metal,melting point:660.4℃, boiling point: 2467℃,density: 2.70 g/cm³,very light, about 1/4 of iron's density.it has low hardness and good ductility, which makes it suitable for being pulled into threadlets or pressed into aluminum foils, and the later is usually used for packaging candy and cigarette. it has good electrical and temperature conductivity. it's used for the manufacture of electric wire and cable in electric power industry, and for the manufacture of cooker in daily life.combined with the magnesium , copper,zinc,tin,manganese,chromium,zirconium,silicon and other elments,it can formulate various alloys that is broadly used for the manufacture of airplane,car,ship, materials of daily living equipment and the doors and windows of construction industry.aluminum is one of the best reflectors of heat and light, so it is used as thermal insulation material and the manufacture of reflecting mirror in the reflecting telescope.
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:does aluminum sheet need to conduct ROHS detection?it's metel material, how much detections should it conduct for ROHS detection?
It's ok for detecting four items of ROHS heavy metal for ROHS detection of metal material.
