The new Oriental Yuhong YH-101 oil-based polyurethane grouting fluid and YH-201 water-based polyurethane grouting fluid are launched in three product specifications of “15 times, 20 times, 25 times” and two specifications of “7kg, 20kg” Various packaging specifications meet industry standards, meet physical performance and environmental protection indicators, and can respond to different needs and rapid repairs of various common water leaks. For underground engineering leakage, the product cures quickly and can quickly stop water; the single component is ready to use out of the barrel, making construction convenient, reducing costs and improving efficiency.
Oriental Yuhong YH-101 oily polyurethane grouting fluid
Upgrading is not just about appearance, but also a comprehensive improvement of inner strength. In terms of performance, compared with the first-generation product, Dongfang Yuhong YH-101 oily polyurethane grouting fluid has more uniform pores and a higher closed cell rate in the foam cured product.
After testing, Dongfang Yuhong YH-101 oily polyurethane grouting fluid has low viscosity, good pourability, and good adhesion to the substrate; the grout foams and expands quickly when exposed to water, with a large expansion multiple*. Under sealing conditions, the product can form a high-strength rigid closed-cell foam. The cured foam has uniform pores and a high closed-cell rate, and is resistant to most organic solvents, weak acids, alkalis and organic microorganisms. Single-component packaging, ready to use, simple and convenient construction, suitable for sealing water leakage in civil buildings, underground tunnels, subway tunnels, highway tunnels, water conservancy and hydropower, mining and other projects, and soil surface improvement and anti-seepage, etc.
Oriental Yuhong YH-201 water-based polyurethane grouting fluid
In this upgrade, Dongfang Yuhong YH-201 water-based polyurethane grouting fluid not only shortens the gel time, but also increases the water expansion rate compared with the first generation product. The consolidated body can better perform in a water environment. Close structural voids.
After testing, Dongfang Yuhong YH-201 water-based polyurethane grouting fluid has good hydrophilicity. It has low viscosity and can self-emulsify and gel quickly when exposed to water. It can be used for grouting construction under humid conditions or water gushing conditions. It has strong adaptability to water quality with different pH levels. The consolidating body of the product is elastomer, which is resistant to most organic solvents, weak acids, alkalis and organic microorganisms. It can swell when exposed to water, which is beneficial to the treatment of water leakage in movable joints. Single-component packaging, ready to use, simple and convenient construction, suitable for anti-seepage treatment of non-structural cracks with certain deformation under long-term water environment in construction, transportation, water conservancy, hydropower, mining and other projects; concrete, rock, soil Quick sealing of water leakage and water inrush; filling of underground honeycomb soil with water, etc.
