　　1、 Working principle of Malisan water blocking reinforcement material:

　　Malisan water blocking reinforcement material is a two-component solvent-free modified polyurethane adhesive liquid, including low viscosity resin A and curing agent B. Liquid resin A can quickly cure with curing agent B within tens of seconds, and the interpenetrating network molecular structure generated by the reaction gives the cured material high mechanical strength, high adhesion, good toughness, and stamping resistance. Resin has low viscosity and good fluidity, which can effectively penetrate into small cracks in coal/rock layers. During the reaction process, non-toxic gases are released to ensure the cleanliness and safety of the site while achieving the construction objectives.

　　2、 Precautions for Malisan water blocking reinforcement materials:

　　1. The product should be stored in a sealed container to avoid moisture absorption. During storage and transportation, direct sunlight exposure is prohibited, and ventilation, light avoidance, and water prohibition should be implemented. Store at room temperature (15-35) in a well ventilated room with strict sealing; A decrease in temperature and an increase in viscosity of liquid components can affect the effectiveness of use and the performance of the resulting products.

　　2. This product is not classified as a flammable liquid, substance, oxidant, corrosive substance, toxic substance, or radioactive hazard during storage, transportation, or handling. Carbon dioxide, foam or dry powder fire extinguishers can be used to extinguish the fire, or a large amount of water can be used to spray the fire.

　　3. Be careful during operation. When opening the lid, slowly release the gas inside the bucket to prevent the raw materials from splashing onto the skin and eyes. If necessary, wear protective equipment. Once splashed onto the skin or eyes, rinse immediately with clean water for at least 15 minutes, and wash the skin with soapy water. It is strictly prohibited to take or accidentally consume. Please seek medical attention immediately for targeted treatment.

　　1、 Characteristics of Malisan water blocking reinforcement material:

　　1. The reaction time is controllable and can be adjusted according to the specific situation of the construction site.

　　2. Low initial viscosity, good permeability, and the ability to penetrate into fine cracks.

　　3. Excellent adhesion to coal seams and rock layers.

　　4. The product only undergoes slight foaming in a dry environment, with almost no change in volume.

　　5. The product can react with water vapor in rock fractures to release non-toxic inert gases, generate secondary pressure, and promote the further diffusion of the slurry into the deep cracks, which has a good repairing effect on fine cracks.

　　Yucheng produces Malisan water blocking reinforcement materials using a unique formula to increase the material's ignition point and reduce its reaction temperature, thus safely overcoming the disadvantages of commonly used chemical grouting materials, such as easy oxidation and spontaneous combustion, and unsafe use. The two-component material is injected into the fractured coal, rock mass, and high emission area through a dedicated gas injection pump and mixing gun, and quickly reacts to solidify with the coal and rock mass to produce a high-strength and resilient solidified body. It can effectively reinforce the soft and fractured surrounding rock underground, prevent water and gas from infiltrating into the underground working room, and effectively fill the high emission area of the working face. After reaction solidification, it has good flexibility and can withstand the deformation of coal rock layers, achieving the effect of strengthening and reinforcing broken coal rock masses.

　　Yucheng brand chemical materials have stable performance, good product quality, and excellent application effects, effectively ensuring the safety of underground workers and providing them with safety guarantees for underground work. They are an indispensable part of coal mines.
