This invention discloses a washing machine drainage control method and a washing machine. The washing machine operates a drainage program, with a drain pump installed at the bottom of the outer tub. Its outlet is connected to a drain hole in the outer tub via a drain pipe, which is inclined. The washing machine's drainage program is divided into four stages. Combined with structural modifications to the washing machine, the control method includes: Stage 1: Starting the drain pump and cyclically starting and stopping; Stage 2: Starting the motor and running at low speed, cyclically rotating with long runs and short stops; Stage 3: Controlling the motor to rotate with short runs and long stops; Stage 4: Controlling the motor to run at high speed. During Stages 2, 3, and 4, the drain pump is controlled to rotate with long runs and short stops. This invention, through structural modifications and drainage timing control, allows water in the drain pipe to flow back into the pump chamber due to the inclined structure of the drain pipe during the drain pump's stop period, pushing air out of the pump's inlet and into the outer tub, thus solving the problem of air trapped in the pump.

This invention discloses a silicate colloid for high-solids-content, high-modulus composite fire-resistant glass and its preparation method, relating to the field of composite fire-resistant glass technology. Specifically, it describes a silicate colloid for high-solids-content, high-modulus composite fire-resistant glass and its preparation method. The colloid, by weight percentage, comprises a silicon source, water, glycerol / ethylene glycol / polyethylene glycol / polyglycerol, water-soluble organic acids and salts, water-soluble metal oxides or hydroxides, and alkali metal hydroxides, wherein the solids content is 60-75% and the modulus is 4.0-5.5. The preparation method includes: uniformly mixing the silicon source, water, additives, and functional additives, then adding alkali metal hydroxides, reacting at 50-90°C to obtain a prepolymer solution, followed by vacuum degassing. The viscosity is adjusted to the desired range by controlling the reaction conditions. This prepolymer solution is suitable for pouring or coating processes. After curing, the colloid forms a fire-resistant glass core layer. The resulting fire-resistant glass has advantages such as high light transmittance, ultra-thinness, dense foaming, low-temperature resistance, high weather resistance, and long lifespan.

This invention provides a pressurized sealing device and method for slurry transport pipelines. The sealing device includes a repair pipe, two sets of drive systems disposed at both ends of the repair pipe, and two sets of pipe-clamping and fixing mechanisms. The repair pipe is fitted over the leak area of ​​the damaged pipe, and at least two sets of sealing strips are provided between the repair pipe and the damaged pipe. The leak area of ​​the damaged pipe to be sealed is located between at least two sets of sealing strips. The drive system includes multiple sets of second hydraulic cylinders, each set of second hydraulic cylinders having one end hinged to a pipe-clamping frame and the other end hinged to a corresponding force-bearing seat on the repair pipe. The two sets of pipe-clamping and fixing mechanisms provide positioning gripping points on both sides of the leak point in the slurry transport pipeline, providing force points for the second hydraulic cylinders. The repair pipe covers the damaged slurry transport pipeline, and the sealing operation of the pipeline transport system is completed under the drive of the second hydraulic cylinders. This invention can complete pressurized sealing operations of slurry transport pipelines, preventing pipeline blockage and ensuring the safety of the slurry transport system.

The application relates to the technical field of concrete pavements, and discloses a reinforced material for concrete pavements and a use method thereof. The reinforced material comprises dry materials and wet materials. The dry materials are as follows: 200-400 parts of white cement clinker, 70-120 parts of modified mineral powder, 300-700 parts of tailing sand, 50-140 parts of lithium slag powder and 5-50 parts of pigment. The wet materials comprise component 1 and component 2. The component 1 is composed of 10-30 parts of nano silicon oxide sol, 10-20 parts of polyaluminum, 10-30 parts of sodium silicate, 5-20 parts of aluminum sulfate, 5-10 parts of urea and 100-300 parts of water. The component 2 is composed of 5-10 parts of glue powder, 5-10 parts of 3-aminopropyltrimethoxysilane and 80-90 parts of water. The dry materials are sprayed on the surface of the concrete by a spraying machine or are uniformly vibrated on the surface of the concrete by a vibrating screen, and the wet materials are sprayed on the surface of the concrete by a sprayer, and then are collected and smoothed, so that the problems of low strength, easy falling and alkali return of the traditional reinforced material are solved.
