Gainike plastic spraying sealing material consists of Material A and Material B. The coating formed after their reaction has a strong sealing function, which can effectively cover the surface of coal-rock roadways and prevent air leakage from entering and harmful gases from overflowing. The coating has excellent adhesion and ductility, with an elongation at break exceeding 100%, enabling it to efficiently cope with the dynamic secondary fracturing of the roadway surface and significantly improve the effect of blocking air leakage. Meanwhile, this material can inhibit the weathering of the roadway surface and effectively prevent the rusting and failure of metal components such as anchor nets (cables) and trays.

Gainike Roadway Surface Spraying Sealing Material (JPF-Ⅰ) is a specially developed inorganic material for the spraying and sealing of roadway surfaces. The material is composed of multiple inorganic components and has excellent adhesion, ductility and sealing performance. After being sprayed on the surface of coal-rock roadways, it can form a dense and firm protective film, which can effectively seal the surface cracks of roadways, prevent air leakage and the overflow of harmful gases, and also play a role in anti-weathering and anti-rust of the roadway surface and metal components.

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.
