Foam Agent 
Model: BYFPM-010 
Different soil may be met in the shield tunneling construction. The properties of the foam agent for the tunnel shield which our company developed for the clay layer is: 
1.Improving the soil plasticity, maintaining excavation face stability. 
2.Increasing the flow of soil, reducing the friction coefficient. 
3.Homogenizing the soil, adjusting the earth cabin pressure. 
4.Reducing the adhesion of the clay on the shell and the knife disc, effectively reducing the torque. 
The using concentration of this product in water is 2％~5％, the expansivity of 1 liter of BYFPM-010 is 25-30, therefore it can produce about 1000 liters of foam. 
This product is non-toxic, tasteless, non-corrosive, biodegradable, when accidentally splashed into the eyes, rinsing eyes with a large amount of water.
