Development and Application of Hydrogen Peroxide Stabilizer for Chemi-Mechanical Pulp
With unique cost-effective advantages,domestic capacity of chemi-mechanical pulp has increased significantly.Hydrogen peroxide is the preferred bleaching agent for chemi-mechanical pulp bleaching.However,hydrogen peroxide is easily affected by catalytic interference such as metal ions,resulting in rapid and ineffective decomposition and reduced bleaching efficiency.Special hydrogen peroxide stabilizer needs to be added for this purpose.Starting from the hydrogen peroxide decomposition mechanism,this paper discusses the advantages and disadvantages of the main components of hydrogen peroxide stabilizer and product development ideas,and proposes and optimizes the laboratory application evaluation process of the stabilizer.Based on operational experience,the precautions for using hydrogen peroxide stabilizer are proposed.
