　　Explanation of raw materials for polyurethane exterior wall insulation materials used in coal mines

　　Polyurethane exterior wall insulation material, mining polyurethane exterior wall insulation material, polyurethane insulation material, raw materials for exterior wall insulation material

　　Usage method of polyurethane external wall insulation material for coal mines:

　　Firstly, perform basic treatment to make the roof (wall) basically flat, without floating ash or oil stains. Function characteristics: Fixed foundation for moisture insulation

　　1. Spray rigid polyurethane foam

　　The rigid polyurethane foam is sprayed on the base surface by special equipment to form a layer of dense foam immediately. According to the thickness of the insulation layer, a construction work surface can be sprayed several times, and the construction work surface on the same day must be continuously sprayed on the same day. After 24 hours of spraying construction, a handheld planer can be used for local trimming. Function characteristics: excellent waterproof and thermal insulation properties.

　　2. Batch application of plastering adhesive

　　The polyurethane foam surface shall be coated with plastering mortar. During construction, the surface shall be flat and keep certain humidity. Function and Characteristics: Ensure the strength of the exterior layer.

　　3. Add mesh cloth

　　Cover the fiberglass mesh cloth on the surface of the adhesive before it dries, and press the mesh cloth into the adhesive with a batch knife. Function and characteristics: After the adhesive is dried and solidified, the force between its mesh cloth can play a role in crack resistance and effectively prevent water leakage.

　　Polyurethane external wall insulation materials for coal mines are mainly made of isocyanates and polyethers, mixed with various additives such as foaming agents, catalysts, and flame retardants through specialized equipment, and foamed on site by high-pressure spraying. Polyurethane rigid foam is a new type of synthetic material with insulation and waterproof functions. Its thermal conductivity is low, only 0.022-0.024W/(m? Κ), which is equivalent to half of extruded polystyrene board and has the highest thermal conductivity among all insulation materials currently available.

　　Tai'an Yucheng produces a variety of mining chemical materials, including Malisan mining sealing and plugging materials, mining rock reinforcement materials, mining water blocking reinforcement materials, mining coal rock reinforcement materials, and Rokexiu mining composite filling materials; Organic mining filling materials, mining grouting and water blocking materials, coal seam roof reinforcement materials, coal mine gas blocking materials, coal mine roof caving grouting and water blocking materials, Malisan rapid spray sealing materials, polyurethane exterior wall insulation materials, and more. No matter which material you need, we can provide it. Welcome to come and purchase.
