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 the bubble apear a few minutes later after putting aluminum sheet into diluted hydrochloric acid?
Aluminum element is extremely activated and will react with oxygen, generating aluminum oxide, once being exposed in air, so there is a layer of aluminum oxide on the surface of daily aluminum products including aluminum sheet. When aluminum sheet is put into diluted hydrochloric acid, aluminum oxide on the surface will firstly react with hydrochloric acid, generating aluminium chloride and water, the process won’t generate bubble, but after finishing the reaction of aluminum oxide on the surface, when the exposed aluminum element reacts with hydrochloric acid, generating aluminium chloride and oxygen, the bubble appears.
Q:what kind of abradant should be used in the deburring of aluminum sheets? How to grind?
we usually use resin grind stone to grind aluminum sheets, Vibration Grinding Mill is also ok.
Q:How to clean the engine oil and kerosene on the surface of aluminum sheet?
it will disappear after rubbing with petrol.
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:How could two pieces of aluminium flakes be welded together?
its welding strength is very high. you can use the following methods to weld two pieces of aluminum sheets together: 1, strict deformation control requirement. 3, it can prevent some flux remnant during welding. 3,the welding wire welding of low temperature M51 and M51-F is operated under 179︒C.or they are welded in the situation of being especially thin.4, it can solve the welding of 3 series aluminium alloys and casting, and its welding temperature is 380-400︒C.its advantage is that you don't need any flux during welding. WE53 low temperature aluminium welding wire has a high affinity in welding 7 series aluminium alloys. and Q303 low temperature aluminum welding wire has a high affinity for the welding of 1 series aluminium alloys, die casting or 6 series welding materials.
Q:what's the size of aluminum sheet circle?
Aluminum sheet circle’s size is usually the width of coil stock (mm) : 500-1250,800-1400,1000-1600, thickness of coil stock (mm) : 0.4-3.0,1.0-6.0, weight of coil stock (kg) : 8000,10000, diameter of blank(mm) : 85-660,85-750,100-900. Aluminum sheet circle is broadly used in electron, daily chemical industry, medicine, education and car accessories industry. Electrical appliance, thermal insulation, machine manufacturing, cars, spaceflight, military industry, mould, construction, printing and other industries. Kitchenware, such as non-stick pan, pressure cooker, etc. and hardware, such as lampshade, shell of water heater, etc. they are one of the highly processed aluminum products with largest consumption.
Q:how to find 0.6mm waste strake of aluminum sheet?
ask door and window maker for some strake.
Q:as for heating coil and aluminum sheet, which one is better for heating?
Both of them have advantage. It depends on the new product type it’s applied. Heating coil: it’s applied in some products with high temperature and large heat release, such as oven and other types.
Q:How to polish aluminum sheet to be bright?
you must do some protection work, or you will fail once aluminum contacts air. Aluminum sheet is easy to be oxided and volatilized.
