Industry insiders analyze that in the future, China's papermaking chemicals industry will focus on the development of supporting chemicals for grass pulp and chemicals required for fiber regeneration, and gradually develop and apply chemicals for neutral sizing agents.
China's paper industry uses non-wood fiber as the main raw material, and non-wood pulp fiber accounts for 60%. Due to the extensive use of grass fibers with short fibers and poor strength, the quality of paper and paperboard products has been greatly affected. Therefore, the structure of paper-making chemicals that are used to produce high-grade paper and other paper mouths in combination with plants and trees will shift to paper pulp chemical structures mainly composed of straw pulp or full straw pulp for the production of high-grade paper and other paper products. The emphasis is on series of straw chemical additives such as enhancers, brighteners, and sizing agents.
Due to the lack of domestic wood fibre resources, the recycling of fibres has gradually received attention. China has introduced several sets of equipment that uses imported waste paper to make high-grade paper, and uses imported waste paper to recycle pulping equipment. The industry believes that it should vigorously organize the production of its supporting waste paper deinking agent, especially the flotation deinking agent. In addition, the research, development, application, and promotion of chemicals such as enhancers and sizing agents for the production of high-grade paper from recycled paper should be well done.
According to the international trend of the paper industry shifting from acidic sizing to neutral sizing, companies should develop and produce neutral sizing agents and their various types of chemicals. Due to the abundant resources of rosin in China, the development of emulsion rosin and near-neutral emulsion rosin sizing agent is still the main task at this stage. Therefore, in the future, the neutral sizing agent should gradually develop.
Industry experts suggest that in the next few years priority should be given to the development of retention aids, filter aids, enhancers, and sizing agents. The main varieties include modified starches, neutral sizing agents AKD, SR, wet enhancer WS-1, and rosin emulsions. , And with the oxygen bleaching process matching chemicals such as ethylenediamine acetic acid (EDTA), diethylene triamine pentaacetic acid (DTPA) and so on.
