The invention discloses a phase-change energy-storage heat-preservation composite material as well as a preparation method and application thereof, and particularly relates to the technical field of heat-preservation composite materials. The phase-change energy-storage heat-preservation composite material comprises the following raw materials in percentage by weight of dry materials: 30%-60% of fly ash, 10%-30% of cement, 5%-20% of lime, 10%-80% of sodium sulfate decahydrate and 0.05%-0.2% of aluminum powder. The method for preparing the phase-change energy-storage heat-preservation composite material comprises the following steps: S1, uniformly dry-mixing the fly ash, the cement, the lime and the sodium sulfate decahydrate; s2, adding water into the dry mixture, and stirring to form slurry; s3, aluminum powder is added into the slurry, and the mixture is poured into a mold after being stirred; s4, standing and aerating to form a porous blank body; s5, the blank body is subjected to maintenance; and S6, cooling and post-processing to obtain a finished product. According to the phase-change energy-storage thermal-insulation composite material and the preparation method thereof provided by the invention, the fly ash is used as a main raw material, the process is simple, and the phase-change energy-storage thermal-insulation composite material has the advantages of excellent phase-change energy storage and temperature regulation functions.

The invention discloses a backlight display data signal processing method, a backlight driving chip and a backlight module, and the backlight driving chip carries out the shaping processing of a received backlight display data signal, obtains a backlight display data signal represented by a square wave, determines a slope adjustment gear based on a received control instruction, and carries out the adjustment of the slope. And adjusting the rising edge and the falling edge of the backlight display data signal represented by the square wave based on the slope adjustment gear to obtain a target backlight display data signal, and sending the control instruction and the target backlight display data signal to a next-stage backlight driving chip. As the target backlight display data signal sent to the next-stage backlight driving chip is the signal obtained after the rising edge and the falling edge are adjusted, the rising and falling speed of the signal can be reduced, EMI can be reduced, and compared with an EMI reduction mode provided by the related technology, the chip size, noise, heat and cost can be reduced.

The application relates to the technical field of corrosion detection, and discloses a battery box integrated corrosion detector and a corrosion detection method thereof. The integrated corrosion detector comprises a detector body; a loading cavity is arranged in the detector body, a PCB is arranged in the loading cavity, a metal detection piece is connected to the PCB, and sealing glue covering the PCB is filled in the detector body, so that the PCB is arranged in a sealed environment, and the metal detection piece is exposed to an external environment. The application realizes online monitoring of the corrosion state in the battery box through differential corrosion response of the bimetallic detection piece. The bimetallic detection piece is used to realize real-time monitoring of the corrosion state in the battery box through resistance change. A long-stroke detour structure can be selected to expand the detection area and range, nitrogen blowing and active dehumidification are combined, corrosion early warning and initial intervention are synchronously completed in a sealed state, the disassembly and inspection risk is reduced, and the battery life is prolonged.

The present application relates to the technical fields of deep-sea mining, and especially relates to a deep-sea mining hydraulic conveying relay station and a hydraulic lifting mining system. The deep-sea mining hydraulic conveying relay station comprises a stock bin and a feeding pipe. The stock bin comprises an upper stock bin and a lower stock bin. The upper stock bin is provided with a fixed baffle. A sliding baffle is arranged between the upper stock bin and the lower stock bin. The sliding baffle and the fixed baffle separate the stock bin into independent injection space and settling space. The sliding baffle is in sliding connection with the stock bin and can rotate around the central axis of the stock bin, so that the injection space and the settling space are alternately changed. The feeding pipe comprises injection pipes respectively connected to the injection space and the settling space. The injection pipe connected to the injection space is in an open state. The present application can reduce the blockage and ore overflow in the stock bin, realize continuous and uniform feeding, and has low requirements for the structure pressure resistance and is environment-friendly.
