9105 Oil Soluble Polyurethane Chemical Grouting Material

9105 Oil soluble polyurethane chemical grouting material is a chemical grouting material which is generated through the reaction of polyether polyol and polyisocyanate and terminated by isocyanate. The material can be foamed rapidly when exposed to water, and the volume of the material may be expanded instantaneously. The generated pushing force can effectively promote the diffusion of slurry, so as to quickly stop the leakage of water . The product is single-component environment-friendly product with no pungent odor. The foaming body can be automatically extinguished when being removed from the fire, and it is especially applicable for the construction in the closed environment.

The product is single-component environment-friendly product with no pungent odor. The foaming body can be automatically extinguished when being removed from the fire, and it is especially applicable for the construction in the closed environment.
 
◆Advantages

·The product has good hydrophobicity and chemical stability;

·The product has good chemical resistance (such as acid resistance and alkali resistance);

·The reaction is rapid and the curing time can be adjusted (usually within tens of seconds to several minutes);

· When the product is foamed freely, the expansion ratio can reach more than 2500%, and the product has good diffusion radius;

· During the restrained expansion ratio test, the consolidated body has a certain compressive strength and can be used as reinforcement material;

·The product has good environmental performance and certain flame retardancy, and can be applied to the construction in relatively confined and poorly ventilated space.

 
◆Scope of Use

· Waterproof treatment and reinforcement treatment for the soil on the tunnel portal where the metro tunnel shield entering and leaving the tunnel;

· Rapid sealing treatment for karst terrain cavity in water conservancy and hydropower project;

· Rapid plugging treatment for large flow gushing water in various buildings and foundations.
