Description
- C-G511S is a polymer well cement fluid loss agent. Assemble of AMPS, well anti- temperature and anti-salty as main monomer and others monomers of anti-salty. Molecules contain quantity of perssad of －CONH2、－SO3H、－COOH with strong absorption, have important function on anti-salt, anti-temperature, absorb free-water, fluid losing.
- C-G511Swork well disperse and anti-salt, can be used in low density and high density cement slurry system, which can be thickened by supreme fine solid phase materials, good competibleness with other additives.
- C-G511S cement slurry configured with ,strength grow quickly in earlier period, well flowability, stable, few dissociated liquid, non-retard, strength grow fast.
- C-G511S can be used to make cement slurry system with sea water, no specific requirement to sea water.
