The particle mean size of aluminum dust is 1-100 mum, and the aluminum dust is lack-lustre, sepia, and good oxidation resistance. The average emissing ability of infrared band is 0.50-0.65.

The invention provides a detonation and ignition charge in extinguishing devices and its coating process, which comprises mixing potassium perchlorate and fine ball-type aluminum dust into solid article, mixing with external adhesive solution, coating onto the main charge and ignition surface, then air-drying.

The invention discloses an automatic machining device for aluminum alloy handle production, and belongs to the technical field of aluminum alloy polishing. The automatic machining device for aluminumalloy handle production comprises a first box body, a supporting cover and a handle body, wherein the supporting cover is fixedly connected to the top of the first box body, a moving mechanism is arranged on the supporting cover, the bottom of the moving mechanism is fixedly connected with a first air cylinder, the output end of the first air cylinder is connected with a second box body, a secondmotor is arranged in the second box body, and the output end of the second motor is connected with a grinding piece. The automatic machining device for aluminum alloy handle production is simple in structure and convenient to operate; through mutual cooperation of a cam and a spraying nozzle, when the handle body is polished, the phenomenon that aluminum dust flies everywhere is avoided, and the health and safety of workers are guaranteed; and through mutual cooperation of the second motor and a second air cylinder, the polishing efficiency is greatly improved.

The invention provides an automatic burr and foil dust brushing removing machine for aluminum foil and relates to the technical field of treatment devices for the aluminum foil for aluminum electrolytic capacitors. The automatic burr and foil dust brushing removing machine comprises a machine frame. An aluminum foil rotary driving motor is arranged on the machine frame. A motor shaft of the aluminum foil rotary driving motor is connected with a hollow supporting shaft for being sleeved with a whole coil of aluminum foil. First brushes corresponding to the left end face of the aluminum foil are arranged on the machine frame. A brush support is slidably connected to the machine frame through sliding rails. Second brushes corresponding to the right end face of the aluminum foil are arranged on the brush support. A first air cylinder used for driving the second brushes to get close to or get away from the right end face of the aluminum foil is further arranged between the machine frame and the brush support. The first brushes and the second brushes each comprise a hollow brush body and bristles arranged on the brush body. Dust sucking holes are formed in the side, where the bristles are located, of each brush body. A cavity of each brush body is connected with a dust collecting mechanism through an air sucking pipeline. The two ends of the aluminum foil are cleaned simultaneously through the first brushes and the second brushes static relative to the first brushes. Under the action of the dust collecting mechanism, aluminum scraps and aluminum dust adhering to the edge of the aluminum foil are sucked away and removed, the removal effect is good, the efficiency is high, pollution to air is low, and the product quality is improved easily.

The invention provides dedusting equipment and a technology for combustible dust environment. The dedusting equipment comprises a dust-absorbing device, a dedusting tank, a discharge valve, and a collecting tank; the air discharge pipe of the dust-absorbing device is arranged in the dedusting tank, the air discharge opening of the air discharge pipe is soaked in white oil in the dedusting tank; and the collecting tank is connected to the lower end of the dedusting tank through the discharge valve. Because the aluminum dust can explode easily, an explosion-proof blower fan is adopted to absorb the dusts. At the same time, the dedusting equipment is provided with a collecting tank, white oil is directly filled in the collecting tank, the aluminum powder is blown into the collecting tank through the air discharge pipe and is stored in the collecting tank, and the discharge valve is arranged between the space over the collecting tank and the dedusting tank. The equipment can be disassembled directly, can collect the aluminum powder, prevents the aluminum from contacting the air so as to prevent dust nuisance and reactions, and guarantees the safety of production and dedusting operation.

The invention discloses a light honeycomb electrostatic dust removal purifier. According to the structure, a customized aluminum honeycomb plate is adopted as a dust collection plate, integrated type strip electrodes are made of metal materials, the aluminum honeycomb plate is fixed to the shell by a fixing plate, the two integrated type strip electrodes are installed on a fixing strip to form a total electrode net, the total electrode net is connected with the aluminum honeycomb plate through an insulation piece, the total electrode net is connected with high voltage power supply negative electricity, and the aluminum honeycomb dust collection plate is connected with high voltage power supply positive electricity. In the working process, an ionization area and a dust collection area are formed for filtrating. Air enters the dust removal purifier from the direction of the aluminum honeycomb dust collection plate, is ionized through integrated type strip electrode needle ends and then enters the dust collection area. The ionization area can damage constituent molecules of organic matter, degrade organic matter and meanwhile enable the dust particles to be charged, the dust particles are adsorbed to the aluminum dust collection plate under the effect of dust collection area electric field action, and meanwhile the floating dust removal and smog removal effects are achieved. The light honeycomb electrostatic dust removal purifier is large in dust collection area, low in air resistance, easy to manufacture and convenient to clean, and greatly saves labor and using cost.

This invention relates to a rustless steel slag-forming and degassing agent, which is specifically a casting accessory material to clean up rustless steel molten steel surface and improve rustless steel quality, and belong to metal surface treatment technique area in foundry industry. This agent mainly comprises 70-80 wt% of dolomite, 10-15 wt% of aluminum dust and 6-15 wt% of fluor. The components are mixed completely in normal temperature and packed to completed product. This invention possesses the properties of increasing life of brasque to more than 200 times; improving slag-forming ability to decrease endermic points, decrease surface points and pocks of buffing surface and increase rate of finished products and improving thermal insulation and degasification by floating constantly on the surface of molten steel, in which molten steel is prevented to contact with air and oxygenized, suck in hydrogen and nitrogen and interfused with foreign substance, so as to ensure cleaner molten steel higher property.
