Alkalinity degradation agent discolors the solution

An alkalinity-degrading agent is a chemical that can cause a color change in a solution. After the alkalinity degradation agent is added to the solution, its molecules will react with the alkaline substance in the solution, resulting in a change in the acidity and alkalinity of the solution, which in turn causes the color of the solution to change.

Alkalinity regulator

Alkalinity regulator is also called medium regulator, pH regulator. One of the regulators in flotation reagents. It is used to adjust the pH of the pulp to facilitate the action of other agents with the mineral surface and eliminate the influence of harmful ions in flotation. Such as lime, sodium hydroxide, sulfuric acid, sodium carbonate, etc.
