1.Sodium hydroxide, commonly known as caustic soda, caustic soda, or caustic soda, with the chemical formula NaOH, is a highly corrosive inorganic strong alkali,
2.At room temperature, caustic soda is a white solid in the form of flakes, granules, or blocks, which is easily soluble in water and releases a large amount of heat. It also has strong hygroscopicity, is easily deliquescent, and can react with carbon dioxide in the air to produce sodium carbonate. Therefore, it needs to be sealed and stored.
3.As a cornerstone product in the chemical industry, caustic soda has high purity and strong stability, and is widely used in multiple industrial fields. It is an indispensable core raw material for modern industrial production.
Core product features
Strong alkalinity and corrosiveness: Caustic soda has extremely strong alkalinity and can undergo neutralization or metathesis reactions with acids, acidic oxides, salts, etc. It has a corrosive effect on metals, glass, leather, and other substances, and also has excellent saponification, emulsification, and degreasing abilities.
High purity guarantee: The purity of industrial grade caustic soda is ≥ 96% (superior products ≥ 99%), and the purity of food grade and reagent grade caustic soda can reach over 99.5%. The impurity content is extremely low, which can meet the strict requirements of different scenarios and ensure the stability of the production process and product quality.
Solubility and reactivity: Caustic soda is highly soluble in water, ethanol, and glycerol, with significant heat release during dissolution. The aqueous solution is strongly alkaline (pH ≥ 13); Fast reaction rate, capable of rapid chemical reactions with various substances, improving production efficiency.
Strong stability: When stored under sealed and dry conditions, caustic soda has stable chemical properties, is not easily decomposed, has a long shelf life, and is convenient for long-distance transportation and long-term storage.
Main application areas
Chemical industry: caustic soda is used as a basic chemical raw material for the production of soap, synthetic detergents, synthetic fibers (such as polyester and nylon), pulp for papermaking, petroleum refining, rubber recycling, etc; It is also a key raw material for the preparation of chemical products such as borax, sodium cyanide, formic acid, oxalic acid, etc.
Textile printing and dyeing industry: caustic soda is used for desizing, boiling, and silk finishing of cotton fabrics, which can remove impurities, oils, and pulp on the surface of the fabric, enhance the water absorption and dyeing uniformity of the fabric, and improve the luster and feel of the textile.
Paper industry: Caustic soda is used in the pulp making process to decompose lignin, separate fibers, and produce bleached and unbleached pulp. It is the core raw material for the production of various types of paper such as toilet paper, news paper, and packaging paper.
Water treatment industry: caustic soda is used to adjust the pH value of sewage and neutralize acidic wastewater; As a coagulant auxiliary treatment, it can remove heavy metal ions, suspended solids, and organic matter from water, and is widely used in industrial wastewater treatment and municipal sewage treatment.
Food industry (food grade): Caustic soda is used for processes such as peeling, decolorization, and neutralization of acidity in food processing. If it is used for vegetable peeling, dairy product processing, seasoning production, etc., it must comply with the national food safety standards (GB 5175-2018).
Pharmaceutical and reagent industry (reagent grade): Caustic soda is used for chemical reagent preparation, drug synthesis, laboratory analysis, etc. It has high purity and low impurities, meeting the precision requirements of scientific research and pharmaceutical production.
Safety and Storage Guidelines
Safety protection: When operating caustic soda, it is necessary to wear acid and alkali resistant protective clothing, protective gloves, goggles, and gas masks to avoid direct skin and eye contact; If accidentally in contact with caustic soda, immediately rinse with plenty of flowing water for more than 15 minutes and seek medical attention promptly.
Storage conditions: Caustic soda should be sealed and stored in a dry, ventilated, and cool warehouse, away from sources of fire and heat, and avoid mixing with acids, flammable materials, oxidants, etc; Caustic soda packaging should use corrosion-resistant materials (such as polyethylene drums, fiberglass drums) to prevent leakage.
Transportation requirements: During the transportation of caustic soda, it is necessary to load and unload gently to avoid packaging damage; Follow the transportation regulations for hazardous chemicals, post warning signs for "corrosive substances", and strictly prohibit mixing with food and drugs during transportation.
