MAPEDRILL BIO LV
Natural, bio-degradable, low-viscosity polymer for mechanized tunnelling and drilling
Where to use
Slurry shields
Mapedrill Bio LV is a low viscosity product; it can effectively replace bentonite, thus enabling the preparation of fluids with no solids content.
Thanks to its suspension quality, Mapedrill Bio LV is able to prevent the segregation phenomena, which normally slow down the discard materials removing operations.
Fluids prepared with Mapedrill Bio LV have a high lubricating effect, thus avoiding Mapedrill Bio LV has a lubricating effect for mechanized tunnelling, significantly reducing tool wear and cutter face torque (especially in presence of fine particles) and enhancing TBM performance.
EPB
The use of Mapedrill Bio LV gives more stability to the foam produced with foaming agents, also inhibiting clay swelling.
Mapedrill Bio LV acts on the foam bubbles, gluing them together, improving foam density before and during the injection. Moreover, during mucking operations, Mapedrill Bio LV improves the stability of the spoil, inhibiting the settling of excavated solids.
Mapedrill Bio LV lubricates the EPBM, reducing torque, cutter wear and accelerating process.
Mapedrill Bio LV, thanks to its formulation and as well the liquid form, do not require any specific mixing equipment (such as high shear mixer).
Consumption
A slurry for Hydroshield: from 0.2 to 2.0%.
As foaming stabilizer from 0.3 to 1%.
As polymer for brattice stabilizing mud from 0.2 to 2.0 kg/m3.
