This product is a polymer grouting plugging material chemically synthesized from polycyanate and polyhydroxy polyether. This material undergoes a chemical reaction when it comes into contact with water to form an elastic colloidal solid body, thereby achieving a good water-stopping purpose. Polyurethane grouting material is a grouting material used in rock and civil engineering projects to block water, prevent seepage, and reinforce. It reacts immediately when it comes into contact with water, and its volume expands rapidly to form a gel that is insoluble in water and has high strength and elasticity. It is widely used in waterproofing and plugging underground projects, strengthening building foundations, stabilizing complex strata, strengthening dam foundations, preventing tunnels from dripping, strengthening broken bodies, strengthening subway foundations, strengthening bridge foundations and cracks, and water-stopping and reinforcement in mine construction.
YN-C909 Liwang water-soluble polyurethane grouting material
Implementation standard：JC/T 2041-2010
- Product Features
- When the slurry meets water, it disperses, emulsifies, and foams by itself, and immediately undergoes a chemical reaction to form an impermeable elastic colloid solid body with good water-stopping performance .
- The elastic colloid solid formed after the reaction has good ductility, elasticity, impermeability, and low temperature resistance, and can maintain its original shape in water for a long time ;
- After mixing with water, the viscosity is low and the pourability is good ;
- When the slurry reacts with water to form an elastic solid substance, it releases CO2 gas . With the help of gas pressure, the slurry can be further pressed into the voids of the structure, so that the porous structure or stratum can be completely filled and compacted. It has the characteristics of secondary permeability ;
- The slurry has good expansion properties, large water content, good hydrophilicity and pourability. At the same time, the viscosity and curing speed of the slurry can be adjusted as needed ;
- Polyurethane has strong adhesion with soil particles, forming a high-strength elastic consolidation body, which prevents the foundation from deformation, cracking, and collapse, thereby strengthening the foundation ;
- The viscosity and curing speed of the slurry can be adjusted. The grouting equipment and process are simple and the investment cost is low. The oil-soluble polyurethane grouting material consists of two components: the main slurry and the accelerator, while the water-soluble polyurethane grouting material is a single-component material .
- Scope of application
- Sealing cracks, expansion joints, construction joints, and structural joints in various buildings and underground concrete projects ;
- Drilling wall plugging and reinforcement in geological drilling projects ;
- Grouting of reservoir dams in water conservancy and hydropower projects, plugging and preventing leakage of cracks in water transfer tunnels, and reinforcing cracks in dam concrete ;
- Strengthen and stabilize the roadbed of high-rise buildings, railways and high-grade highways ;
- Water blocking in tunnels during coal mining or other mining projects, reinforcement of broken layers such as roof ;
- Strengthening of bridge foundations and cracks in bridge bodies ;
- Reinforcement of deformed buildings, reinforcement of gaps in concrete structures such as water towers and pools, and prevention of subsidence ;
- Soil improvement, soil surface protection and stabilization reinforcement, etc.
- Precautions
- Please wear protective equipment (such as gloves, goggles) during construction to avoid direct skin contact. If contaminated, rinse with plenty of water.
- This product is a solvent material. During construction, attention should be paid to ventilation and away from fire sources. Before the material is solidified, open flames should not be used around the construction area.
- After using the machine, clean it immediately with detergent until it is completely clean.
