DSTA tape has a large number of hydrophilic groups, which can be adsorbed on clay particles, DSTA makes use of its long molecular chain to form the network structure, it interacts with water to form an adsorption hydration film, which increases the mud viscosity, increases the shear force and reduces wall filtration loss. The strong suspension ability can effectively ensure that the mud has enough capacity to carry sand and cuttings, which can ensure the whole wall is clean, safe, and preventing wall collapse.
Recommended dosage: 0.25%-0.33% of the mud system.
