Synthetic polymer in liquid form for water based fluids to be employed in mechanized tunnelling and drilling
Where to use Mapedrill F2 has a stabilizing effect on mixed round and/or very altered formations and has an encapsulating/inhibiting effect in active clays. Mapedrill F2 has a strong lubricating effect, reducing torque and wear and thereby increasing machine performance. Due to its liquid form, Mapedrill F2 allows for fast fluid preparation and, because of its excellent dispersive properties, can be used quickly even without complex mixing plants. The treated ground becomes homogeneous and the polymer does not accumulate, rather spreads universally. Mapedrill F2 has excellent cutting carrying capacity and inhibits hydration in active formations. Mapedrill F2 is not toxic and does not damage the formation. Mapedrill F2 can be used in conjunction with our foaming agents, having an excellent stabilizing action on the foam, improving compactness and strength. In presence of hard water and water rich in ions of calcium and magnesium, it is advised to pre-treat the water with carbonates of sodium or magnesium. This will enhance the Mapedrill F2 polymer action.
Dosage As tunnelling slug: from 2 to 5 kg per1000 l of water. As stabilizing foam agent: from 2 to 4 kg per 1000 l of water. Our laboratory is available for assessing the dosage of Mapedrill F2 with the soil types met during tunnelling and/or drilling. To make the best use of Mapedrill F2 it is recommended to contact our “Underground Technology Team” technical service to verify and improve the characteristics, according to the local application conditions.
