FS PHS Hydrogen peroxide stabilizer
Sodium silicate traditionally used as a peroxide stabilizer in the peroxide bleaching of mechanical, chemi-mechanical and deinked pulp may cause deposits and runnability problems downstream, for example spots and holes in the paper. It also has a significant impact on cationic demand downstream in the process.
Our replacement of silicate-free polymer with good bleach effect is FS PHS.
FS PHS has good bleach effect as hydrogen peroxide stabilizer when it is used in pulp-making and textile pretreatment process. It can control Hydrogen peroxide decomposition rate in different PH value, and it is acted as chelate agent for all kind of heavy metal ion in solution.
