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 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 present application relates to a moisture-proof control method, device, equipment and air conditioner for a compressor. The method includes: acquiring operating parameters, temperature data and weather parameters of the environment of the compressor; When the weather parameters of the environment meet the preset conditions for entering the moisture-proof mode, the compressor is heated to increase the internal temperature of the compressor junction box. The operation parameters, temperature data and the weather parameters of the environment where the compressor is collected are used as the basis for judging whether moisture protection is required. If the preset conditions for entering the moisture-proof mode are met, the compressor is heated to increase the internal temperature of the compressor junction box. , Increase the temperature of the compressor with corrosion risk to avoid moisture corrosion, which can reduce the failure rate of corrosion and rust inside the compressor in a humid environment, and also ensure the normal operation of the compressor in harsh environments and prolong its service life.
