GUIDELINES FOR USE
Application:
Soilax® AC can be used with standard foam generators on Earth Pressure Balance (EPB) Tunnel Boring Machines (TBMs). Foam can be injected directly onto the cutting face through the cutterhead, into the excavation chamber, or into the screw conveyor.
Dosage:
The concentrate dosage, Foam Injection Ratio (FIR), and Foam Expansion Ratio (FER) all depend on the conditions of the soil encountered. Typically, Soilax® AC concentrate is diluted between 0.2%-4% with water. In cohesive clays FIR in the range 20%-50% and FER between 1:1 and 4:1 are expected.
Required Equipment:
Soilax® AC is compatible with standard foam generators. For applications such as cleaning of conveyor belts, the diluted solution may be sprayed directly onto the area.
To prevent mixing of non-approved additives, it is recommended to use a dedicated transfer and/or dosing pump for Soilax® AC. If a single pump is used for more than one product, the pump should be thoroughly cleaned with water before switching to Soilax® AC.
STORAGE AND HANDLING
Temperature and Shelf Life:
Soilax® AC should be stored between 40°F and 105°F (5°C and 40°C). Do not allow product to freeze. If stored in the original tightly closed containers, Soilax® AC will have a shelf life of 12 months.
