The production of paper, a fundamental material in modern life, relies on a complex series of chemical processes, with Sodium Hydroxide (NaOH), or Caustic Soda, playing a pivotal role. In the pulping stage, Caustic Soda is essential for separating cellulose fibers from lignin, a complex polymer that binds wood fibers together. This separation process is key to producing high-quality paper. NINGBO INNO PHARMCHEM CO.,LTD. supplies industrial grade Sodium Hydroxide critical for these operations.

The primary function of Sodium Hydroxide in papermaking is within the Kraft process, also known as the sulfate process. In this method, wood chips are cooked in a solution of sodium hydroxide and sodium sulfide, referred to as white liquor. This alkaline environment causes the lignin to break down and dissolve, freeing the cellulose fibers. The effectiveness of Sodium Hydroxide in dissolving lignin is crucial for obtaining a pure cellulose pulp, which is the fundamental building block of paper.

The chemical reaction facilitated by Caustic Soda breaks the ether linkages within the lignin molecule, making it soluble in the alkaline solution. This process not only liberates the cellulose fibers but also helps in removing other non-cellulosic components from the wood. The efficiency of lignin removal directly impacts the brightness, strength, and overall quality of the final paper product.

NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of consistent quality in the chemical supply chain for the paper industry.
