The invention discloses an antirust method for a stirring kettle. Firstly, the inner wall of the reaction kettle is cleaned with clean water, and after cleaning, air-dried, and then the reaction kettle is further dried with a slight fire to ensure that the reaction kettle does not contain liquid or water vapor. After drying, coat a layer of silica gel on the wall of the reaction kettle. The silica gel has the characteristics of large moisture absorption and small volume expansion, so as to prevent the reaction kettle from being corroded by moisture. In addition, take an appropriate amount of anhydrous copper sulfate, which is a white crystal, grind it, and sprinkle it on the thin sponge pad, and the copper sulfate powder will be in the gaps in the thin sponge pad. The sponge pad also has a certain ability to absorb moisture. When the sponge pad turns blue, it means that the anhydrous copper sulfate turns blue when it meets water, and moisture has entered the sponge pad. So the anhydrous copper sulfate in the sponge pad is used to indicate whether the reactor is damp. Spread a thin sponge pad on the reactor, then cover the outer layer with a plastic film and seal it to ensure that the reactor is separated from the outside world and avoid moisture, thus completing the moisture-proof and rust-proof work of the reactor.

The invention discloses a solar charging station comprising a containing groove provided with an opening, a pair of steel plates, a support portion, a base plate, a photovoltaic group, a support column, a charging pile, a pair of second electric cylinders and a central controller. Fixing ends of the pair of steel plates are in shaft connection with the containing groove. The support portion comprises a pair of first electric cylinders and support plates. The pair of support plates is fixed on the internal wall of the containing groove. Each of the fixing ends of the pair of first electric cylinders is fixed on one support plate, and each telescopic end of the pair of first electric cylinders is in fixed connection with one steel plate. The photovoltaic group comprises a photovoltaic panel and a photovoltaic inverter. The photovoltaic panel is in electric connection with the photovoltaic inverter. The support column is in fixed connection with the photovoltaic panel. The charging pipe is connected to the photovoltaic inverter. The support column, the photovoltaic inverter and the charging pile are fixed on the base plate. Fixing ends of the pair of second electric cylinders are fixed on the bottom portion of the containing groove, and telescopic ends of the pair of second electric cylinders are fixedly connected to the base plate. The central controller comprises a single-chip machine and a server. Solar charging of the solar charging station of the invention is realized; photovoltaic elements are effectively protected; and the solar charging station is lasting and durable.

The invention relates to a method for preparing a colored decorative board for a bathroom and the colored decorative board, comprising a main body of the colored decorative board, the main body of the colored decorative board includes a waterproof layer, an anti-deformation layer and a decorative layer; the anti-deformation layer is located between the waterproof layer and the decorative layer. Between the decorative layers; the waterproof layer includes white cement, quicklime, oxidized paraffin wax soap, polyurethane material and acrylic emulsion; the anti-deformation layer includes high alumina cement, mineral stone powder, magnesium oxide and quartz sand; the decorative layer Including ordinary cement, reflective material particles, polymer wax, colored aggregates and pigments; the invention makes the decorative board have strong waterproof performance, prevents the decorative board from being corroded by moisture, and makes the decorative board have strong anti-deformation performance, avoiding decoration Thermal expansion, deformation, and cracking of the board, while making the decorative board have an obvious aesthetic feeling, improving the sense of experience.

The invention discloses an assembled sports wooden floor. The wooden floor includes a fixed board, and the fixed board is fastened with mounting frames distributed in arrays for fixing solid wood boards. One end of the board is slidably provided with clamping strips for fastening the solid wood board. The fixed board includes a base plate, which is provided with arrayed chutes, and the base plate is provided with an array of threaded holes for fixing the mounting frame. Symmetrically distributed through grooves are provided, and the through grooves are located between two slide grooves, and pads distributed in arrays are fastened in the through grooves. The sports wooden floor of the present invention is provided with a mounting frame, and a solid wood board is fastened on the mounting frame. Corroded by moisture, the service life of the wooden floor is increased, and the solid wood board is equipped with an insulation layer. In winter, the temperature of the wooden floor is guaranteed to be suitable, so that the athletes will not feel cold.

The invention discloses a building hollow brick which comprises inner and outer hollow rebar net frames with U-shaped cross sections. Space between the inner rebar net frame and the outer rebar net frame is filled with a concrete layer, reinforcing ribs are arranged between the inner rebar net frame and the outer rebar net frame, a cavity is arranged in the middle of the concrete layer and filled with water-absorbent expanding resin, a stainless steel pipe is arranged on the rebar net frames and penetrates the inner rebar net frame and the outer rebar net frame to enable two side end faces of the outer rebar net frame not to be communicated with each other, a PVC supporting pipe is arranged in the middle of the stainless steel pipe, a foam glass layer is arranged at each of two ends of the PVC supporting pipe, and an irregular through hole structure is arranged on each foam glass layer. A structure with the inner and outer rebar net frames is adopted, so that strength of integral structure can be enhanced; the water-absorbent expanding resin is adopted inside, so that outside water can be absorbed, integral structure strength is improved; a graphite plate structure is adopted, so that wear resistance of an outer structure can be improved.
