Polymeric foam and polymeric foam products that contain a foamable polymer material, at least one blowing agent, activated carbon, and water are provided. The activated carbon acts as both a water absorbent and carrier for the water. The activated carbon is able to control and increase cell size even in the presence of carbon dioxide, HFCs, and / or infrared attenuating agents. Additionally, the activated carbon permits a desired amount of water to be introduced into the polymer melt. By controlling the amount of activated carbon and its water content during an extrusion process, a broad range of cell sizes can be obtained in the extruded product. In exemplary embodiments, the activated carbon is added to a primary extruder and water is directly injected into a secondary extruder. Alternatively, the activated carbon is compounded with a polymer resin, pre-hydrated by conditioning or steam impregnation, and added to a primary or secondary extruder.

The invention discloses a low-shrinkage cathode paste, which consists of dry ingredients and a binder, wherein the binder accounts for 16 to 20 percent of the total weight of the cathode paste and the dry ingredients account for 80 to 84 percent of the total weight of the cathode paste; and the dry ingredients comprise electrically-calcined coal, pitch coke and artificial graphite, the electrically-calcined coal accounts for 59 to 65 percent of the total weigh of the dry ingredients, the pitch coke accounts for 5 to 11 percent of the total weigh of the dry ingredients, and the artificial graphite accounts for 27 to 33 percent of the total weigh of the dry ingredients. The requirement on the granularity of a powder material in the electrically-calcined coal is that 200 mesh powder accountsfor 47 to 53 percent of the total weight of the powder material. The requirement on the granularity of a powder material in the pitch coke is that 200 mesh powder accounts for 47 to 53 percent of thetotal weight of the powder material. The requirements on the granularity of the artificial graphite are that the granularity of the artificial graphite is less than 4.5 millimeters, that a granular material accounts for 30 to 36 percent of the total weight of the artificial graphite, and that a powder material accounts for 64 to 70 percent of the total weight of the artificial graphite. Powder having a granularity of 200 meshes accounts for 47 to 53 percent of the total weight of a powder material in the artificial graphite. Compared with the prior art, the cathode paste has the advantages ofimproving the surrounding environment of an aluminum potroom, prolonging the service life of an aluminum cell, reducing cell voltage, energy consumption and production cost and the like due to reduced electrical resistivity, improved electrical conductivity and obviously reduced expansivity and shrinkage.

The invention relates to a method for complexing, extracting and separating rare earth elements with an acidic phosphorus-type extractant. The main point is to add citric acid or citrate to a rare earth chloride solution to form a rare earth chloride-hydrochloric acid-citric acid mixed solution as the extraction and separation method. The aqueous phase and P204 or P507 acidic phosphorus-type extractant are diluted with kerosene as the organic phase for extraction and separation, and the rare earth elements are separated through extraction, washing and stripping in the extraction tank; the raffinate containing citric acid is returned for recycling. The feature of the present invention is to use the complexation of citric acid and rare earth elements to strengthen the effect of acidic phosphorus type extractant for separating rare earth elements, especially to separate the rare earth elements in the high-concentration rare earth solution REO=200~300g / L; at the same time The acidic phosphorus-type extractant still has a high ability and effect of extracting rare earth elements without saponification treatment. The invention has low investment, low production cost and reduced environmental pollution.
