摘要： PURPOSE:To obtain a damping metal plate low in the temp. dependence of damping properties and having good vibration absorbability, by holding plate- shaped expanded graphite between two metal plates. CONSTITUTION:Plate-shaped expanded graphite 3 is held between two metal plates 2, 2. The expanded graphite is obtained by a method wherein graphite such as natural graphite, pyrolytic graphite or kish graphite is treated with sulfuric acid or sodium nitrate and potassium permanganese or bromine or halide to obtain an interlaminar compound which is, in turn, heat-treated at high temp. to generate gas from the interlaminar compound and graphite interlayers are expanded by said gas. This expanded graphite 3 is held and fixed between the metal plates 2, 2 but, in this case, it is convenient to use an adhesive. As the adhesive, a phenol resin type one is pref.

摘要： PURPOSE:To obtain high-purity iron oxide at low cost by applying treatment such as gravity concentration on hematite ore and/or magnetite ore followed by adding a sodium component to the purified ore fraction therefrom and performing calcination. CONSTITUTION:A raw material 1 such as hematite ore and/or magnetite ore is freed from foreign substances through a screen 2 followed by feeding, via a concentration regulation tank 3, to a cyclone 4 to carry out wet classification. Thence, a fraction of larger size 4A is introduced into an agitation tank 6A, while the other fraction of smaller size 4B into a settling separation tanks 5 to feed the subfraction of larger size 5A into a second agitation tank 6B. The both fraction 4A and subfraction 5A are fed to coarse particle- and fine particle-table dressing machines 7, 8 respectively, to perform gravity concentration. The resulting purified ores 9A, 10A are each incorporated with a sodium component such as solid NaOH to carry out sodium calcination 11 followed by washing 12 and filtration 13 to eliminate the impurities contained, and the filtrate fraction is classified by a second cyclone 14, the resultant fraction of larger size 14A being ground 15 and classified 16, then fed to the next process into a product 21, whereas the fraction of smaller size 14B is put to recycling use.

摘要： PURPOSE:To increase heat insulation effect by holding a plate body of expansion graphite in the middle of an inorganic mat. CONSTITUTION:A plate body 3 of expansion graphite is held in the middle of an inorganic mat 2. As a result, a function of preventing convection (pass of air) is applied, and the heat resistance is very high. Because heat insulation effect is large, the thickness of a heat insulating material can be small, and the whole device becomes compact. If it is applied for usage where it is exposed to high temperature flames, it can be compact because of insertion of the expansion graphite. This means that reduction of required space can be realized easily by forming a fire proofing structure, etc., compact, and construction for corner parts, folded parts, etc., in installation of the device can be easy and simple because it can be thin.

摘要： PURPOSE:To uniformize the thickness and density of a rolled product sheet by providing a partition plate between an expanded graphite delivery position and a rolling means, sending a gas onto the plate from the upper part, and making the height of the pile of the expanded graphite constant. CONSTITUTION:The raw graphite 1 is expanded by an expansion furnace 2, and delivered onto a belt conveyor 3. The expanded graphite 1' is moved by a belt 3a, and passed through the partition plate 4. The tip of the partition plate 4 is directed toward the upstream side of the belt conveyor 3, and the tip is set below the pile of the expanded graphite 1'. A gas G such as air is injected from an injection nozzle 5, directed downward along the partition plate 4, and blown onto the pile of the expanded graphite 1'. Consequently, the upper surface of the expanded graphite 1' is flattened. The graphite is then passed through a preliminary rolling belt 6A, a rolling roll 6B, and finish rolling rolls 7-10, rolled, and then wound on a winding roll 11.

摘要： PURPOSE:To recover ZnCO3 with hardly any impurities, such as Fe and Pb, by heat-treating a kiln dust in an oxidizing atmosphere, dissolving the heat- treated kiln dust in sulfuric acid and adding Na2CO3 to the resultant solution. CONSTITUTION:Reduced iron is removed from a dust generated from iron mills by using a kiln 5 and the residual kiln dust 6 is heat-treated at >=400 deg.C temperature 7 in an oxidizing atmosphere. The heat-treated kiln dust, as necessary, is then subjected to wet magnetic separation 8, filtration 9 for removing an Fe-rich slurry or directly dissolved in sulfuric acid 10. The resultant sulfuric acid solution is subsequently filtered 11 to remove Fe and Pb left on the filter. On the other hand, Na2CO3 is then added to the obtained filtrate after removing the Fe and Pb and neutralization and crystallization 12 are carried out by exothermic reaction expressed by the formula to recover ZnCO3. The crystallized slurry is subsequently filtered 13 to dry 14 the formed cake using heavy oil, etc., and utilized as a raw material for Zn based plating (e.g. pure Zn, Zn-Fe or Zn-Ni). Na2SO4 is concentrated and separately utilized as Glauber's salt, such as fertilizer.
