　　1、 Explanation of reinforcement materials for mining coal rock Malisan:

　　Malisan Mining Coal Rock Reinforcement Material is a dual liquid polymer grouting product composed of resin and catalyst. The product is constructed by mixing and injecting into the coal rock mass at a volume ratio of 1:1 through a dedicated pneumatic grouting pump and a mixing injection gun. The low viscosity mixture can quickly penetrate the fine cracks of the coal rock mass, expand and solidify to produce high-strength, high toughness polymer material. The material has strong bonding force, high mechanical properties, and improves the overall strength of the coal rock mass. Suitable for grouting reinforcement of fractured coal and rock masses underground.

　　2、 Characteristics of Malisan reinforcement material for mining coal and rock:

　　1. The mining coal rock Malisan reinforcement material has strong permeability and bonding strength,

　　2. Coal rock Malisan reinforcement material for mining is flame-retardant and has a low reaction temperature,

　　3. Polymer has high strength and toughness, can adapt to long-term ground pressure changes, and is easy and fast to construct.

　　4、 Precautions for using Malisan reinforcement materials for mining coal and rock:

　　1. The product needs to be stored in a dry and cool place, away from heat sources, and strictly protected from direct sunlight and rain.

　　2. Resin and catalyst should avoid direct contact with the skin and be protected during construction. During operation, every effort should be made to avoid the infiltration of moisture.

　　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.
