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:why intact aluminum sheet stop quicker than pectinate one in the magnetic field?
while swinging in the magnetic field, intact aluminum sheets will formulate inner eddy current,that is the annular induced current.eddy current will transform the mechanical energy into heat energy, which makes the aluminum sheet stop quickly.but pectinate aluminum sheet can't formulate intact eddy current, so intact aluminum sheet stop quicker than pectinate one.
Q:why does the bubble apear a few minutes later after putting aluminum sheet into dilute sulphuric acid?
Because there is oxide on the surface of aluminum, the reaction will be quicker after polishing the oxide with abrasive paper.
Q:Which kind of glue is best for bonding aluminum sheets?
502
Q:does aluminum sheet has a function of magnetism isolating?
yes.
Q:who knows the ceiling technology of aluminum sheet?
Construction technology of ceiling aluminum sheet: (1) firstly check keel’s quality, the straight shape and uniformly forced state of boom, control the keel’s gap within 500mm, reduce the gap according to design requirement under humid environment. The lower surface of keel is smooth without a sense of bearing down, main device is closely connected with accessories, it can be bound after being confirmed qualified.(2) we should break the board along the cutting line and ensure the margin of cutting board straight and square without any chipping or arris defect. (3) while placing and fixing the board, we can place edge of aluminum-plastic panel(encapsulated edge) in the vertical direction of supporting keel, there is a phenomena of hanging. Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. You can start from a plate angle or middle position, and don’t place them at the same time. Slab joint should be straight and in the same width, without break joint. (4) in the process of joint, Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. And the butt joint should be stagger, the butt joint can’t be connected on the same keel. When you use doubling plate, the joints of the second layer board and the first layer board can’t be connected with the same keel, double-deck gypsum board should be staggered joints.
Q:Which kind of glue can bond two pieces of aluminum sheets?
you can use jellied universal glue, don't use the liquid one, because it's only suitable for plastics or materials easy for erosion.
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.
Q:why is copper sheet but not aluminum sheet that becomes the negative pole after putting copper sheet and aluminum sheet connected with wire into concentrated nitric acid?
it may be that aluminum won't react with concentrated nitric acid.
Q:how to separate the aluminum sheet in plastic?
Put them into clean water if both of them won’t react with water, and aluminum sheet will sink into the bottle, then fish up them separately.
