Summary
OBC-LL30 is a type of nanoscale material. The product is uniform and stable with high specific surface area so that it has a strong water adsorption capacity and can effectively bind the interstitial water in cement slurry to control and reduce free liquid.
OBC-LL30 can rapidly improve the cementing speed of cement slurry and has good reinforcement performance.
OBC-LL30 is applicable to the preparation of low density cement slurry system with high water cement ratio.
