I.Industry
1. Papermaking industry: used to process wood raw materials, remove impurities such as lignin, separate cellulose, and produce high-quality paper.
2. Textile printing and dyeing industry: Before dyeing cotton fabrics, the fabrics are treated with caustic soda solution to remove impurities such as wax and grease on the surface of cotton fibers, thereby improving the water absorption and dyeing properties of the fabrics.
3. Chemical raw materials: It is an important raw material for the production of a variety of chemical products, such as soap, synthetic detergents, fatty acids, glycerin, etc. In soap production, caustic soda reacts with oils and fats to produce soap and glycerin.
4. Petroleum industry: used for refining petroleum products, removing acidic impurities in petroleum, such as sulfides, cyclohexane acid, etc., and improving the quality of petroleum products.
5. Electroplating industry: used for surface treatment of parts before electroplating, to remove oil and rust on the metal surface, to clean the surface of parts, so as to better perform electroplating and improve the adhesion and quality of the coating.
II Agricultural Sector
1. Soil improvement: For acidic soil, applying caustic soda in appropriate amounts can neutralize soil acidity, increase soil pH, improve soil structure, and facilitate the growth of crops.
2. Pesticide production: It is the raw material for producing certain pesticides. For example, in the synthesis of organophosphorus pesticides, caustic soda participates in the reaction and helps to form the active ingredients of pesticides.
III. Life Areas
1. Unclogging pipes: When the pipes are blocked, caustic soda can react chemically with organic matter such as grease and hair in the blockages to decompose them, thereby achieving the purpose of unclogging the pipes.
2. Household cleaning: Some household cleaners contain caustic soda, which can effectively remove stubborn stains such as kitchen grease and floor stains by using its strong alkalinity.
