Sulfonated polymer asphalt powder
1.Properties and applications
Sulfonated polymer asphalt powder synthesis introduces the special functional groups produced by a number of sulfonation process.The product has excellent anti-blocking effect of collapsing fluid loss and anti-pollution electrolyte capacity. The sulfonated asphalt polymer powder oil-soluble materials is high, good water solubility, anti-pollution ability. Soluble part of the plastic under pressure at certain temperature variations in the wall to form multi-point adsorption, pore blocking, played the role of mechanical tension wall rock, with strong blocking effect of anti-collapse. Water soluble part of the cake in the wall to form hydrophobic membrane, increasing the water molecules into the formation of resistance, can reduce the filtration of drilling fluid. While the product also has a certain temperature and salt resistant ability, good compatibility for different depth of the drilling fluid system, no increase in viscosity, non-foaming, do not pollute the environment, to facilitate the construction site.

3.The use method and notice
It can be used directly into the drilling fluid, but the added speed is not too fast to prevent the formation of large micelles; also be dubbed in 1% to 2% of the glue fluid to join, its dosage is generally 0.8% to 2 %.
