Rosin soap foaming agent for cement foaming agent

Cement foaming agent. Because rosin has carboxyl - COOH, adding alkali will produce saponification to produce abietic acid soap, which is called rosin soap. Its main component is abietic acid sodium, which belongs to the category of anionic surfactant. Pine soap is a brownish transparent paste with a water content of about 22%. After being diluted with water, it becomes a transparent and clear liquid without turbidity or precipitation. It has a unique odor of rosin, a pH value of about 8-10, and
