Ammonium persulfate: an excellent additive for the paper industry

In the broad field of paper industry, ammonium persulfate is becoming an indispensable chemical raw material with its unique properties and significant advantages.

Wide range of application scenarios

Pulp bleaching: Ammonium persulfate is a highly efficient bleaching agent that can effectively remove natural pigments and impurities such as lignin from the pulp, greatly improving the whiteness and finish of the paper. Whether it is sulfate pulp, sulfite pulp or mechanical pulp, ammonium persulfate can play an excellent bleaching effect, so that the paper presents a white and flawless quality, to meet the production needs of various high-end paper. For example, in the production of cultural paper, toilet paper, wrapping paper, etc., the bleaching effect of ammonium persulfate(APS) is crucial, which provides a strong guarantee for the appearance quality of paper.

Waste paper deinking: With the continuous improvement of environmental awareness, waste paper recycling has become an important development direction of the paper industry. Ammonium persulfate has excellent performance in the deinking process of waste paper, which can quickly decompose the ink components in waste paper and separate the ink from the fiber, so as to realize the effective deinking of waste paper. After ammonium persulfate treatment, the waste paper fiber can be reused for paper making, which not only reduces the production cost, but also reduces the consumption of forest resources, and makes an important contribution to the sustainable development of the paper industry.

Paper strengthening: In the production process of paper, ammonium persulfate can be used as an oxidizing agent to react with additives such as starch to improve the strength and toughness of paper. Through the treatment of ammonium persulfate, the fiber structure of the paper is more compact, and the mechanical properties such as tensile strength and tearing strength are significantly improved, making the paper more durable and not easy to break during the use of printing and packaging. This is of great significance for the production of high-quality printing paper and packaging paper.

Significant advantages and characteristics

Strong oxidation brings high performance: Ammonium persulfate is highly oxidizing, and its oxidation capacity is much higher than other common bleach and oxidizing agents. This enables it to quickly and thoroughly complete bleaching, deinking and other tasks in the paper industry, greatly improving production efficiency. Compared with traditional bleach, the amount of ammonium persulfate is less, but the effect is more significant, which can save a lot of raw material costs for enterprises.

Good water solubility is easy to operate: ammonium persulfate is easily soluble in water, and can quickly disperse and play a role in water. This makes it very convenient to add and use in the paper production process, without complex equipment and processes, just add it to the pulp or wastewater in accordance with a certain proportion, after stirring, reaction and other simple operating steps, you can achieve the desired effect. At the same time, the good water solubility also ensures the uniform distribution of ammonium persulfate in the paper, ensuring the stability of the quality of the paper.

Environmental safety in line with industry trends: In the context of today's environmental protection era, ammonium persulfate has obvious advantages. It does not produce harmful by-products during use and has less pollution to the environment. Moreover, the products after decomposition of ammonium persulfate are mainly harmless substances such as oxygen and ammonium sulfate, which will not cause harm to human health and ecological environment. Therefore, the use of ammonium persulfate is in line with the development trend of green environmental protection in the paper industry, and can help enterprises meet the increasingly stringent environmental requirements.

Stable quality guarantee Continuous production: ammonium persulfate has good stability and is not easy to decompose and deteriorate during storage and transportation. This ensures its quality stability in paper production, so that enterprises can use ammonium persulfate for a long time and stably, ensuring the continuity of the production process and the consistency of paper quality. Whether it is a large-scale paper production line or a small paper workshop, ammonium persulfate can provide reliable quality assurance.
