Q:How could two pieces of aluminium flakes be welded together?
You can use argon arc welding, connect the positive pole with alternating current,aluminum wire as the welding wire.
Q:Which kind of solution should I use while welding aluminum sheet and copper pipe by tin soldering?
1, you must use over 350W soldering iron, 2,prepare some borax and tin soldering paster, you can’t use rosin to weld it, 3, polish the pipe to clean with fine abrasive paper and borax, 4, put the pipe and sheet into borax, use the soldering trip to rub on the weldment with some borax. 5, after the pipe and sheet become hot, use the soldering iron with the paster and tin to rub the pipe and sheet in borax, then it can be welded. 6, they can be welded together after welding.
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:what's the size of gap while pressing 6mm aluminum sheet?
unilaterial gap is 0.1-0.15mm, and you can change the gap according to cutting effect.
Q:When water continually sprays on the aluminum sheet, how to avoid corrosion of aluminum sheet and keep its water resistance?
aluminum will react with oxygen, generating dense Al2O3 oxide film on the surface, once the pure aluminum is exposed in air, it will react with air, generating oxide film to protect it.
Q:Could ring-pull can be transformed as aluminum sheet?
Ring-pull cans will be reused after recycle, there are parts of ring-pull cans be transformed as aluminum sheet.
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 solve the loose bonding of aluminum sheet and silica gel?
Bonding silicone rubber needs surface treatment, after using silicone rubber surface treating agent of Kuer , you can bond them with 4211 adhesive.
Q:what’s the difference of activated aluminum and aluminum sheet?
you can use weak acid ,weak base solvent or steam to clean the oil and dirt on the surface, it's activated aluminum, their difference is that activated aluminum has porous structure oxide film.
Q:As for cast aluminum sheet or wrought one, which one has faster heat conduction?
1,duralumin: it's the alloy of aluminum, copper, magnesium, manganese and other metals. it's suitable for compacting by rolling, and it has a higher strength and hardness than common aluminum products. 2, aluminum: it contains many inpurities, is crisp and easy to be smashed.cast aluminum usually is secondary aluminum, and it is produced by remelting the collected old aluminum pots and spoons.3, wrought aluminum: it contains 98% aluminum and 2% or more inpurities, and is comparatively pure aluminum. its soft priority makes it suitable for being pressed into various shapes, aluminum pots,aluminum lunch box,aluminum sheets,aluminum wires,aluminum pipes are all made by wrought aluminum.you will know their defferences from their definition.
