Potassium hydroxide (KOH) is an inorganic compound with the chemical formula KOH. It is commonly referred to as caustic potash due to its highly alkaline nature. KOH is available in various forms, including solid pellets, flakes, and solutions. In the paper-making industry, KOH is typically used as a white, odorless, and water-soluble substance.
In the initial stages of paper production, wood chips are subjected to a process called digestion. During this step, the wood chips are cooked in a mixture containing Potassium Hydroxide. The alkaline nature of KOH helps break down the lignin, a complex polymer that binds wood fibers together, facilitating the separation of cellulose fibers.
Potassium Hydroxide is also instrumental in the deinking process, where used paper is recycled. Inks and other contaminants present in the recovered paper are removed through the use of KOH. The alkalinity of Potassium Hydroxide aids in breaking down ink particles, allowing them to be washed away effectively.
Sizing is a crucial step in paper making that determines its ability to resist water absorption. Potassium Hydroxide is utilized to modify the sizing properties of paper, making it more resistant to liquids and improving its printability.
Maintaining the correct pH level is essential during various stages of paper production. Potassium Hydroxide serves as an effective pH adjuster, ensuring optimal conditions for chemical reactions and the stability of the paper-making process.
KOH's strong alkaline properties help enhance the strength and durability of paper. It reacts with cellulose fibers, increasing their bonding and leading to paper with improved tensile strength and tear resistance.
Potassium Hydroxide is highly effective in breaking down lignin during digestion, resulting in higher pulp yield and improved paper quality.
It promotes efficient ink removal during the deinking process, facilitating the recycling of used paper.
