A method of manufacturing a high-strength aluminum alloy extruded product which excels in corrosion resistance and stress corrosion cracking resistance, and is suitably used in applications as structural materials for transportation equipment such as automobiles, railroad carriages, and aircrafts. The method includes extruding a billet of an aluminum alloy containing 0.5% to 1.5% of Si, 0.9% to 1.6% of Mg, 0.8% to 2.5% of Cu, while satisfying the following equations (1), (2), (3), and (4), 3≦Si%+Mg%+Cu%≦4 (1) Mg%≦1.7×Si% (2) Mg%+Si%≦2.7 (3) Cu%/2≦Mg%≦(Cu%/2)+0.6 (4) and further containing 0.5% to 1.2% of Mn, with the balance being Al and unavoidable impurities, into a solid product by using a solid die, or into a hollow product by using a porthole die or a bridge die, thereby obtaining the solid product or the hollow product in which a fibrous structure accounts for 60% or more of an area-fraction of the cross-sectional structure of the product.
摘要:
Using a positive active material in powder form such as a metal salt or graphite fluoride, an anode for use in an electric cell, and particularly suitable for use in an organic electrolyte cell, is produced by the steps of dispersing the active material, and a conductive material such as carbon powder where necessary, in a solution of an organic polymer used as binder in a suitable liquid, mixing the dispersion with another liquid in which the polymer is substantially insoluble so as to cause precipitation of the polymer in a state intimately mixed with the active material and the conductive material, separating the solid phase mixture from the liquid phase and drying it, and press-shaping the dried mixture into an anode body of a desired shape. By mixing the binder with the active material in this manner, it is possible to obtain an anode body sufficient in mechanical strength and high in electrochemical activity by using only a very small amount of binder.
摘要:
A lubricant comprising a partially defluorinated graphite fluoride obtained by exposing a dispersion of raw material graphite fluoride to electromagnetic radiation, followed by the separation of the resulting partially degraded graphite fluoride. The partially defluorinated graphite fluoride is not only excellent in lubricating properties but also has excellent compatibilities with resins, greases and oils. The excellent compatibilities of the partially defluorinated graphite fluoride are effective in preventing the unfavorable deposition of the graphite fluoride in a liquid lubricant composition and advantageously lead to improvement in the moldability of any graphite fluoride-resin composition, thereby enabling the ultimate composition to exhibit excellent lubricating properties.

摘要:
The invention relates to water-repellent composite grains. Each composite grain includes: a first grain; and a low molecular weight polytetrafluoroethylene (PTFE) covering the first grain. The first grain is higher than the PTFE in mechanical strength. With this, the composite grains are improved in mechanical strength. A water-repellent article is produced by anchoring the composite grains to a substrate through an adhesive layer formed on the substrate. The composite grains are partly exposed on the adhesive layer and partly submerged in the adhesive layer. With this, the water-repellent article is made minutely rough. The water-repellent article is improved in mechanical strength and water repellency.
