The invention relates to an application of an ion conduction membrane containing chlorinated polyvinyl chloride in a flow battery. The ion conduction membrane is prepared by blending chlorinated polyvinyl chloride and ion exchange resin and then performing curing through a solvent evaporation method. By introducing the chlorinated polyvinyl chloride, the problem that the membrane stability of thenon-fluorine ion conduction membrane is reduced due to the introduction of ion exchange groups is remarkably solved, the blended membrane has high ion conductivity, and the fluorine ion conduction membrane also has high vanadium resistance and chemical stability.

The invention discloses a titanium-series polyester catalyst and a method thereof for producing copolyester. The catalyst is obtained by the reaction of titanate, ethylene glycol and phosphoric acid ester. A copolyester chip is produced by using the catalyst, and the intrinsic viscosity of the chip is 0.75 to 0.81dl/g, the b value is between 1 and 3.5. The copolyester product provided by the invention is characterized in that the copolyester product has the advantages of neutral color, high intrinsic viscosity and good transparency, and can be widely applied to the markets of plates, sheets, high-performance heat shrinkable films, bottles and the like.

The air compressor oil composition has the advantages of environment-friendliness, capability of saving energy and reducing consumption and excellent oxidation resistance. The invention further relates to the preparing method of the air compressor oil composition.

The invention relates to the field of chemical additives, and discloses a flavoring agent. The flavoring agent comprises the following components in percentage by mass: 5 to 30 percent of flavoring base, 5 to 20 percent of anhydrous sodium sulfate, 32.5 to 45 percent of anhydrous dextrose, and 32.5 to 45 percent of maltodextrin. The flavoring agent has higher solubility, so that the blocking of equipment pipelines is avoided. Meanwhile, the anhydrous dextrose and the maltodextrin are used as nutrient substances to take part in the nutrition synthesis and metabolism of animals, and assist feeds and veterinary medicines to exert effects to the maximum extent; and the flavoring agent can be widely used for the preparation of the feeds and the veterinary medicines.

The invention provides a molding and foaming process of a macromolecule with supercritical rapid swelling through mold pressing. The problem of low production efficiency of supercritical foaming materials due to the long contact penetration time between polymers and gas during supercritical mold pressing foaming is solved. Supercritical fluid and a polymer melt can be mixed quickly and evenly through mechanical stirring of a screw in a charging cylinder of an injection molding machine, and after a homogeneous solution is injected from the injection molding machine to a mold cavity, through regulation of the temperature and further diffusion of the supercritical fluid, regulation of the melt strength before foaming and further increasing of the gas solubility can be achieved. A two-step grading method of melt blending and solid swelling foaming can ensure rapid diffusion and swelling of the supercritical fluid in a polymer matrix, the advantages of mold pressing foaming products are remained, meanwhile, the problem of the too long swelling time caused by gas diffusion in existing mold pressing foaming processes is solved, the production efficiency of mold pressing foaming is significantly improved, and industrialization of supercritical mold pressing foaming is further promoted.
