This invention discloses a polymer antistatic wood-plastic composite flooring, relating to the field of wood-plastic composite flooring, comprising joists and wood-plastic composite panels. At least two joists and wood-plastic composite panels are provided, with the two joists arranged parallel to each other and the two wood-plastic composite panels slidably fitted onto the tops of the two joists. A connecting structure is provided on adjacent sides of the two wood-plastic composite panels. In practical operation, when the wood-plastic composite panels are installed outdoors, rainwater will enter the interior of the moisture-proof ring through the heat dissipation holes during rainy weather and drain out from both ends of the moisture-proof ring, reducing the accumulation and erosion of rainwater on the top of the wood-plastic composite panels, thus improving service life. The addition of multiple sets of heat dissipation holes increases the friction on the top of the wood-plastic composite panels, preventing slippage during rainy weather. Because rainwater drains quickly, it dries rapidly after the rain stops due to wind and temperature variations.

This application provides a bottled hydrogen peroxide filling device, belonging to the field of hydrogen peroxide production technology. The bottled hydrogen peroxide filling device includes a base, a filling machine mounted on top of the base, and a filling head connected to the output end of the filling machine. A lifting mechanism for moving the filling head up and down is mounted above the base, and a sealing mechanism for blocking the bottle opening during filling is also mounted above the base. By controlling a motor, as the hydrogen peroxide level in the bottle rises, the filling head gradually rises, keeping it close to the liquid surface. Because hydrogen peroxide is corrosive, the filling head does not immerse itself in the liquid. Although this method greatly reduces hydrogen peroxide splashing, some splashing still occurs. When filling to near the bottle opening, hydrogen peroxide can still easily splash out. A baffle can effectively prevent hydrogen peroxide from splashing out of the bottle opening.
