Gainike Inorganic High-Efficiency Filling Material for Closed Wall (JCT-Ⅰ) is a specially developed inorganic filling material for efficient filling and blocking of permanent closed walls. The material consists of two powder components, Material A and Material B. According to on-site requirements, it is mixed with water in a certain proportion to make a premix, which is then fully mixed by a slurry mixing device to form an inorganic solid material. After the mixed slurry is poured into the cavity of the permanent closed wall, on the one hand, it has a good function of penetrating and blocking broken holes and cracks in the surrounding rock; on the other hand, it can achieve a complete roof-contacting effect.

Gainike Inorganic Self-Foaming Filling Material (JWT-Ⅲ) is an inorganic material with antistatic properties. It adopts innovative foaming technology, enabling room-temperature chemical self-foaming and room-temperature curing of inorganic materials. Compared with organic polymer materials, this material features low usage cost, no heat release, and high safety, meeting the requirements of light weight, sealing, load-bearing, high efficiency, and environmental friendliness. It is particularly suitable for filling and plugging broken areas, cavities, and air leakage channels in coal seam environments such as underground upper/lower corners, goafs, roof fall areas, etc.

Gainike Inorganic Foam Spraying Material is an inorganic fire prevention and extinguishing material for plugging air leakage, mainly used for spraying on air leakage cracks in roadway sides and oxygen-isolating spraying on exposed coal sides. The material has high compressive strength, no obvious exothermic reaction, and neither burns nor supports combustion. The construction process is wet operation, producing no dust. Compared with organic polymer materials, this material is low in price, inherently safe, and meets the requirements of safety, light weight, sealing, and environmental protection. Its Application Process is simple: when in use, it is mixed with water in a certain proportion to form a slurry, which is pumped out by a grouting pump. Compressed air is introduced into the injector to form foam, which is then sprayed on the target area. The final formed inorganic foam can effectively seal the surface cracks of coal and rock roadways, preventing air leakage and the overflow of harmful gases.

Gainike inorganic foam filling material is an inorganic fire prevention and extinguishing material used for filling and plugging air leakage. It is mainly applied to corner plugging and open cavity filling. This material is a single-component inorganic mixture with a simple Application Process. When in use, it is mixed with water in a certain proportion to form a slurry, which is pumped out by a grouting pump. Then, compressed air is introduced into the foamer to form foam. The material has no reaction exotherm, neither burns nor supports combustion. Compared with organic polymer materials, this material is low in price, inherently safe, and meets the requirements of safety, light weight, sealing and environmental protection.

Gainike inorganic self-foaming filling material is used by mixing material A (powder), material B (liquid) and water in a certain proportion. It is a completely inorganic material with absolute flame retardancy and antistatic properties, neither burning nor supporting combustion. It adopts innovative foaming technology to realize normal-temperature chemical self-foaming and normal-temperature curing of inorganic materials. Compared with organic polymer materials, this material has the advantages of low price, no heat release and good safety, meeting the requirements of light weight, sealing, high efficiency and environmental protection. It is especially suitable for filling and plugging broken areas in contact with coal such as upper and lower corners, goafs, roof caving areas, as well as hollow areas and air leakage channels.

When the coal-oxygen inhibitor is mixed with water and sprayed onto the surface of coal, it forms a polymer protective film on the coal surface. This protective film has multiple effects: it can not only block the contact between coal and oxygen, inhibit coal spontaneous combustion, and extend the coal storage period, but also effectively suppress the flying of coal dust, avoiding environmental pollution and weight loss caused by wind, rain and erosion.
