Cement Anti-Sedimentation Agent

Brief Introduction:

effectively improve the sedimentation stability at high temperature of high suspension capability.

BCJ-300S is compounded with inorganic and organic materials which can effectively improve the sedimentation stability at high temperature for it has high suspension capability. BCJ-300S won’t thicken too much at normal temperature and won’t thin excessively at high temperature. It is suitable for, in particular, high temperature deep well and horizontal well.

 

BCJ-310S is compounded with inorganic and organic materials which can effectively improve the sedimentation stability of low-density slurry. Besides it has less impact on the mixture,hardly thickening properties and other adverse effects to slurry.  Especially it is used for poor stability of slurry system.
