摘要： A method for inhibiting silica scale formation which treats aqueous systems containing silica with a bottle brush polymer. The bottle brush polymer includes a repeat unit obtained after polymerization of one or more anionic monomers, and a repeat unit obtained after polymerization of one or more polyoxoalkylene-containing monomers. The bottle brush polymer may further include a repeat unit obtained after polymerization of one or more nonionic monomers. The addition of the bottle brush polymer to the aqueous system results in the inhibition of silica scale.

摘要： A method of inhibiting silica and silicate scale formation via treating an aqueous system containing silica with an effective amount of a chelating agent blended with a polymeric dispersant in a weight ratio range from greater than 1.0:0.5 to less than 1.0:3.0, agent to dispersant, including blends in a weight ratio of 1:1. Specifically, the chelating agent is either EDTA or DTPA, while the polymer dispersant is an acid and alkylene oxide derived dispersant.
