NINGBO INNO PHARMCHEM CO.,LTD. supplies a range of industrial chemicals, with Pentetic Acid (DTPA) being a key component for the pulp and paper sector. The production of high-quality paper often involves complex chemical processes, and DTPA plays a critical role in optimizing several of these stages, particularly in bleaching and de-inking.

One of the most significant applications of DTPA in the pulp and paper industry is its use as a stabilizer for hydrogen peroxide bleaching. Hydrogen peroxide is a common bleaching agent used to achieve whiteness in paper pulp. However, its effectiveness can be significantly compromised by the presence of trace metal ions, such as iron, manganese, and copper, which are often found in wood pulp or process water. These metal ions catalyze the decomposition of hydrogen peroxide, leading to a loss of bleaching efficiency and increased chemical consumption. DTPA acts as a powerful chelating agent, sequestering these detrimental metal ions and forming stable complexes. This action preserves the oxidizing power of hydrogen peroxide, ensuring a more consistent and effective bleaching process, resulting in brighter pulp with less chemical input.

Furthermore, DTPA is utilized in the de-inking process for recycled paper. In this application, DTPA helps to manage metal ions that can interfere with the efficiency of de-inking agents and can cause agglomeration of ink particles. By chelating these ions, DTPA contributes to a cleaner and more efficient removal of ink from recycled paper fibers, leading to a higher quality recycled paper product. The ability to buy DTPA of suitable industrial grade is essential for paper mills seeking to improve their processes and product quality.
