Product description
Natorfluid FA is composed of a combination of various surfactants, stabilizers, enhancers, and penetrating agents, It is an auxiliary material specifically designed for the smooth construction of earth pressure balance shield tunneling machines under different soil conditions. This product has strong adaptability to soil, high foaming rate, and strong stability. It can reduce mechanical wear of shield tunneling machines, stabilize soil structure, and reduce the permeability of slag soil. Especially suitable for impermeable surfaces or surfaces with high fine-grained content, such as mudstone, silt, and clay.
Feature and benefits
- Improve the working performance of soil, form plastic deformation of soil, provide uniform and controllable support pressure, and enhance the stability of the working surface;
- Reduce the internal friction angle of the excavated soil, reduce the internal friction force, and reduce the wear of the soil on the cutterhead and screw conveyor;
- Reduce the torque of the cutterhead to prevent machine failure due to excessive energy consumption and heat generation；
- Reduce the viscosity of the soil, making it less likely for the clay to adhere to the pressure chamber walls and cutterheads, making it less likely for the soil to solidify and cake, and preventing blockages from occurring；
- Reduce the permeability of slag and effectively prevent the occurrence of gushing during excavation；Effective suppression of dust generation in rock tunnel construction;
- Biodegradable and reduces environmental impact.
