Manufacturing process of Aluminium powder

Manufacturing process of Aluminium powder

Aluminum powder could be a fine granular powder made of Aluminium. Aluminum powder is a light, silvery-white to gray, odorless powder. It is a reactive flammable material.

Aluminum Powder is employed within the production of the many forms of explosives and fireworks. it's also used within the manufacturing of certain kinds of electronics.

Powdered aluminum is included in many paints and sealants. Certain products design to hold electrical

current, like solar

cells is

commonly made

using

powder. Rocket propellant is usually made with aluminum and lots of solid rocket fuels are based on chemical reactions involving this metal.

In form of powders, Aluminium is used for several applications such as the manufacture of slurry, explosive and detonators, thermite process used for the manufacture of ferroalloys and for specialized welding applications like rails, pyrotechnic to manufacture crackers, sparkles and other pyrotechnic products; manufacture of aluminum paste, paints and several other powder components employed in automobiles.

For the assembly of aluminum powder, there are several processes, one can use any of

them. The metal is melted in furnaces and therefore the temperature maintained is around 720O to 760OC. Atomized Aluminum is produced by blasting the stream of molten Aluminum into small particles by air jet.

Aluminum manufacture is accomplished in two phases: First phase, the Bayer process of refining the bauxite ore to obtain aluminum oxide, and the Second is, the Hall-Heroult process of smelting the aluminum oxide to release pure aluminum.

Pigments are produced from aluminum powder and almost exclusively manufactured through a wet-milling process. Mineral spirits, an acid lubricant, and aluminum powder are placed in a mill. When the mill is rotated, balls within the rotation chamber cascade the aluminum slurry in a manner that flattens and breaks the resultant flakes on impact.

Manufacturing method

Method for the manufacturing of aluminum powder comprises dry grinding billet aluminum (aluminum powder obtained by atomization of liquid metal, waste aluminum foil, chips) in a very ball mill. Grinding is applied in an environment of noble gas of nitrogen with controlled oxygen content (2 to 10 vol.%). Before grinding to the mixture is added fat Supplement - synthetic carboxylic acid groups C12- C16or higher fatty alcohols of group C16- C20representing the products of oil refining.

The aluminium Powder is manufactured in several forms like flake like particles, granular powder etc. for the assembly of aluminium powder. There are several processes one can use any of them. The metal is melted in furnaces and therefore the temperature maintained is around 720ยบ C to 760ยบ C. Automised aluminium produced by blasting the stream of molten Aluminium into small particles by air jet. For this purpose, an atomizer is employed which consists of a straight tube with lower and dipped in molten metal and upper end terminating as alittle orifice.

A jet of hot air under pressure is undergone through armillary opening near the highest, which impinges on a stream of molten aluminium drawn by suction through the orifice.

This results in the formation of Small particles of aluminium. These particles are drawn by suction through the nozzle and eventually into cyclone collecting system. The particle size is controlled to some extent by varying nozzle opening, gas pressure etc. the various sizes of Aluminium Powders are segregated by sewing. Then packing is finished as per market requirement for specific quality.

Manufacture of aluminum paste, paints and a number of other powder components employed in automobiles. the foremost important property of aluminum powder to undergo an energetic chemical reaction when it gets oxidized finds application in pyrotechnic process. In foundry, aluminum powder is employed as a defoliant and exothermic tapping compound to extend the yield casting.
