Abstract: La présente invention concerne des mélanges de polymères et de polyamides intégrant un réactif renforçateur de morphologie choisi parmi des composés phosphorés tels qu'un hypophosphite. Physiquement, les points remarquables concernent la résistance à la traction et le point Vicat. De tels mélanges à base d'un polyamide et d'un polymère choisi dans le groupe des copolymères d'éthylène neutralisés, et le réactif phosphoré conviennent à la production de pièces moulées, ou fabriquées autrement, et demandant une bonne résistance mécanique et une ténacité élevée. Les pièces moulées produites à partir de tels mélanges font preuve d'une brillance élevée, d'une résistance élevée à l'abrasion et aux rayures, ainsi que de bonnes qualités aux hautes températures.

Abstract: A composite membrane (12) comprising a membrane (16) with a structure of nodes (22) connected by fibrils (24). Surfaces of the nodes (22) and fibrils (24) define a plurality of interconnecting pores (26) that extend through the membrane (16) and between major sides (18, 20) of the membrane. The membrane (16) is made from an expanded polytetrafluoroethylene material which tends to tends to absorb oils and certain contaminating agents. The membrane (16) is moisture vapor transmissive, gas permeable and wind and liquid penetration resistant. A coating (28) is disposed on surfaces of the membrane (16) that define the pores (26). The coating (28) is made from an acrylic-based polymer with fluorocarbon side chains. The coating (28) is coalesced on surfaces of the nodes (22) and fibrils (24) to provide oil and certain contaminating agent resistance to the composite membrane (12) without completely blocking the pores (26) in the membrane (16).A method of treating a membrane (16) comprises the steps of providing a membrane (16) with a structure of node (22) and fibrils (24). Surfaces of the nodes (22) and fibrils (24) define a plurality of pores (26) extending through the membrane (16). The membrane (16) is made from an expanded polytetrafluoroethylene material. A water-miscible dispersion of perfluoroalkyl acrylic copolymer solids in a water-miscible solvent is provided. The water-miscible dispersion has surface tension and relative contact angle properties such that the diluted dispersion is incapable of wetting the polytetrafluoroethylene material of the membrane (16). The dispersion is diluted with a water-miscible wetting agent so the diluted dispersion can wet the membrane (16). Surfaces of the nodes (22) and fibrils (24) are coated with the diluted dispersion. The wetting agent material is removed. Solids in the diluted dispersion coalesce on surfaces of the nodes (22) and fibrils (24) without completely blocking the pores (26) in the membrane (16).

Title: Process for purification of aqueous solution from radionuclides
Inventor: COSOV VILGHELM
IPC: G21F9/04
Filed: 2014-07-17
Abstract: The invention relates to the field of chemistry, in particular to electrochemical processes for purification of aqueous solutions from radionuclides, and can be used for protection of environment from pollution by electrochemical separation and sorption of radionuclides from solutions.The process for purification of aqueous solution from radionuclides comprises the electrochemical treatment of the aqueous solution by solution polarization with periodic current with reverse amplitude and duration adjustable pulse, using the insoluble anode and cathode. The treatment is carried out in repeated stages, each lasting one hour. Before the start of treatment and after the end of each step the solution is filtered and the sediment is removed, while measuring the level of radioactivity of the solution, the intensity of radiation of the removed sediment and the dependence of the anode and cathode potential on the corresponding current density to construct the polarization curves and determine the operating current density range. At the start of treatment the current density is changed from 0 to the working values for 10 min and is carried out the electrolysis for 50 min, the pH of the solution being equal to at least 8, the solution temperature being equal to the room temperature, and the ratio between the mean value of the direct current pulse and the mean value of the reverse current pulse is selected in the range 3.5:1…6:1. In the last stage of treatment, the anode and cathode are placed each in cases of insoluble tissue, in which from the front side are poured sorbents of anionite and cationite nature of a size of 0.5 mm.
