摘要:
Aluminum or aluminum alloy scraps or wastes are broken into chips and extruded under a high temperature to produce extruded structural profiles. The method is characterized by the fact that the interior of the extruder is evacuated prior to or simultaneously with the extrusion step so as to exhaust air entrapped in the body of the chips. There is also disclosed apparatus suitable for performing the method.

摘要:
Method for producing extruded structural profiles from aluminum or aluminum alloy scrap materials. The scrap materials are compacted under room temperature or under heat suitable for hot extrusion into a cylindrical body which is of such a dimension that is suitable for insertion into an extruder. The compacted body has an average density which is 70 to 86 percent of that of aluminum, and includes longitudinal air passages. Suction pressure is applied to the interior of the extruder during extruding process for removing air entrapped in the body, which may otherwise cause voids in the extruded products.

Aluminum or aluminum alloy scraps or wastes are broken into chips and converted into a cylindrical body to be extruded under a temperature suitable to produce extruded structural profiles. The method is characterized by the fact that the interior of the extruder is evacuated prior to or simultaneously with the extrusion step so as to exhaust air entrapped in the cylindrical body.

An aluminum alloy consising essentially of 0.65 to 0.75% by weight of magnesium and 0.50 to 0.60% by weight of silicon or 0.47 to 0.57% by weight of magnesium and 0.75 to 0.85% by weight of silicon, 0.15% to 0.25% by weight of iron, less than 0.05% of an impurity selected from the group consisting of copper, manganese, zinc, chromium, and titanium and the balance aluminum, the aluminum alloy being subjected to aging treatment at a temperature below 200.degree. C for 20 to 50 minutes to obtain 0.2% proof stress larger than 11 kg/mm.sup.2, ultimate tensile strength larger than 20 kg/mm.sup.2 and elongation more than 8%. Aluminum alloy shapes are formed of the above aluminum alloy by extrusion forming of the aluminum alloy to obtain an extrusion, coating a film on the surface of the extrusion with a water-soluble paint after forming thereon a ground film, heating the extrusion at a temperature below 200.degree. C for 20 to 50 minutes to effect printing and hardening of the coated film and age hardening of the extrusion at the same time.
摘要:
A method of forming a colored oxide film on the surface of an aluminum material is disclosed in which the aluminum material is subjected to an electrolytic treatment in an aqueous solution containing sulfuric acid to form an aluminum oxide film containing aluminous oxides and having lattice defects; sulfuric ions in the solution are caused to enter into the lattice defects of the oxide film; some or all of the sulfuric ions are reduced to form sulfur and sulfides; and the colored oxide film is formed using the sulfur and sulfides as coloring sources.

A strong base layer for painting on an aluminous material, a thermosetting resin paint and a painted film having high cohesion and corrosion resistance are produced by forming a boehmite layer in various processes on the aluminous material and immersing the aluminous material provided with the boehmite layer in a water soluble thermosetting resin paint at 40.degree.-60.degree.C containing an organic amine and removing the aluminous material from the paint bath and heating the paint thus deposited on the aluminous material to bake and cure the paint.

摘要:
A method for producing a display comprising: forming a plurality of pixels arrayed on a flexible substrate and independently driven by TFTs, wherein the TFTs are formed in such a manner that the direction of the channel length L between the source and drain of each TFT is the direction of two orthogonal directions on the substrate in which the substrate has a smaller dimensional change ratio than the other direction. When the TFTs include a switching TFT and a driving TFT, the TFTs are formed in such a manner that the direction of the channel length between the source and drain of at least the driving TFT is the direction of the two orthogonal directions on the substrate in which the substrate has a smaller dimensional change ratio than the other direction.
