Sodium hydroxide, also known as caustic soda, caustic soda, caustic soda, flake soda, is an inorganic compound, white solid, soluble in water, and strongly corrosive. It has a wide range of application value in various fields.
In the paper industry, sodium hydroxide is used as a catalyst to accelerate the decomposition of cellulose fibers, remove resins and impurities from wood, adjust pH value, improve the texture and durability of paper, and can also be used for bleaching and processing of paper in the pulp and paper manufacturing process.
In the textile industry, by using sodium hydroxide solution for boiling, the oil and impurities in the cotton fiber are removed, making it softer, smoother and more shiny. In addition, it can also play a neutralizing role in the dyeing and printing process, making the color more vivid.
In drug synthesis, sodium hydroxide is used as an important reactant to make drugs such as aspirin, penicillin, and hormones, while regulating the pH of the drug.
In the food industry, sodium hydroxide can remove impurities and bacteria from food, and can also be used for food preservation and processing.
In agriculture, sodium hydroxide is mixed with acids to form pesticides such as insecticides and herbicides. In addition, it can also be used to adjust the pH of the soil and improve the fertility of the soil.
In the field of environmental protection, sodium hydroxide is widely used in water treatment, it reacts with the acidic substances in the water, converts them into harmless substances, prevents the formation of limescale, and at the same time raises the pH value of the water and improves the taste of the water.
In daily life, sodium hydroxide has the ability to clean and decontaminate due to its strong alkalinity. We often use cleaners containing sodium hydroxide to remove grease and stains. In the industrial field, it is also used to clean oil and gas pipelines, remove rust from metal surfaces, etc.
In conclusion, sodium hydroxide is an important chemical substance with a wide range of applications in the field of chemistry and industrial applications. However, due to its strong alkalinity, safe operating procedures should be followed during use to avoid safety accidents.
