Product name: well-drilling slurry Product description: well-drilling slurry is a kind of light gray powder, which has a good hydrophilicity, electropositive exchangeability, thixotropy, expansibility, suspension and so on. This product is applicable to making the low-water slurry, which has a good lubricity and suspension, that can play a significant role when guarding against the wall of a well to fall the block, preventing collapse and plugging. The bentonite used in civil engineering has a macroviscosity and a great thixotropy, which is applicable to underground continuous wall, cutting-wall construction. It also can be used for the mortar, the caissons, the pile foundation, the soil sealing, the plugging of reservoir dam project, as well as the top pipe slurry use and so on.
