DPS-327 is a new type of drag reducer for cementing with high temperature resistance and salt resistance, which is made of water-based polycarboxylate by spray drying. This drag reducer has outstanding characteristics in high temperature resistance, salt resistance and compatibility with other cement additives.

HCSA-310 is a new powder cement-based early strength agent, which combines a variety of organic and inorganic composite nano-materials. Its action mechanism lies in that by stimulating C-S-H nucleation in the early stage of cement hydration, the polymerization process of hydration products is greatly improved by structure quasi-control technology, which endows cement with high hydration activity, colloidal stability and chemical inertia, and the final crystal grows into a stable structure, which can significantly improve the early strength of cement-based products, enhance the durability of cement products and improve mechanical properties.
