The electrolyte includes solvent, solute, additive for corrosion resistance and property modifying additive. The additive for corrosion resistance includes 8-hydroxy quinoline, mannitol, phosphate monoester and one or more matters selected from organic acids. Compositions of property modifying additive include polyvinyl alcohol and / or carbowax, boracic acid and / or ammonium pentaborate, and glycoletc. Moreover, the electrolyte also includes dehydrogenation agent and waterproof mixture. The electrolyte improves capabilities of high temperature and high pressure resistant, and corrosion proof for aluminum electrolytic capacitor, reduces generation of hydrogen so as to prevent capacitor from blowing up, and hydration causing invalidation of capacitor. The invention also discloses the aluminum electrolytic capacitor of using the electrolyte. The capacitor is operable under rated operational voltage 315V-500V, and temperature 125 deg.C as upper limit.

The invention provides a detachable condenser, which comprises a barrel, a heat exchange tube, a cover plate, a first fixing part, a tubular plate, a sealing device, a seal and a second fixing part. The barrel is used for storing heat exchange materials, the heat exchange tube is mounted in the barrel, the cover plate is arranged on the barrel, the first fixing part is used for fixing the barrel with the cover plate, the center of the tubular plate is connected with the heat exchange tube, the sealing device is arranged between the tubular plate and the cover plate and used for reinforcing sealing effect between the tubular plate and the cover plate, the seal is connected with one side of the tubular plate and used for connection with an external pipeline system, and the second fixing part is used for fixing the cover plate with the seal to enable the cover plate to be more firmly connected with the seal. Using the detachable condenser solves the problem that replacing deformed or corroded parts in the prior art is extremely difficult.

The invention discloses a method for preparing an environment-friendly plastic runway. The method includes: S101: base layer laying; S102: ground repair; S103: waterproof primer coating; S104: base material laying; Vinyl fluoride, EPDM rubber particles, cross-linking agent and coupling agent are added to the reaction kettle in proportion, and then the temperature is raised to 150-170°C by stirring the reaction kettle, so that polytetrafluoroethylene, EPDM rubber particles, cross-linking agent and coupling agent The agent is evenly mixed together, and then the mixed polytetrafluoroethylene, EPDM rubber particles, crosslinking agent and coupling agent are poured into a special spraying machine, which is evenly sprayed on the surface of the substrate by the spraying machine; Tetrafluoroethylene can prevent the deformation of the plastic runway, avoid the subsidence of the compressed part of the plastic surface layer, ensure the normal use of the plastic runway, improve the service life of the plastic runway, and is harmless to the environment and the human body.
