Product Description
Sodium hydroxide, also known as caustic soda, caustic soda, fire soda, and caustic soda, is an inorganic compound with a chemical formula of NaOH and a relative molecular weight of 39.9970.
Sodium hydroxide is highly alkaline and highly corrosive. It can be used as acid neutralizer, masking agent, precipitant, precipitation masking agent, color developer, saponification agent, peeling agent, detergent, etc. It has a wide range of uses.
Product Usage
Chemical industry: Sodium hydroxide is used as an alkaline desiccant in the chemical industry because of its strong water absorption and deliquescent properties. In addition, it is also a catalyst for many chemical reactions and can promote the progress of the reaction.
Papermaking industry: Sodium hydroxide plays an important role in the papermaking process and is mainly used for pulp treatment and bleaching.
Textile industry: In the textile industry, sodium hydroxide is used in the degreasing, bleaching and dyeing processes of fibers to help improve the softness and texture of the fibers.
Soap making: Sodium hydroxide is a key raw material in soap making. It is called a saponification agent and can react oil and alkali to form soap.
Cleaners and Degreasers: Sodium hydroxide is highly alkaline and corrosive, so it is used to make cleaners and degreasers that effectively remove grease, stains, and other hard-to-clean contaminants.
Food processing: In food processing, sodium hydroxide is used to adjust the pH value of food, increase the stability and shelf life of food, and can also be used for cleaning and disinfecting food.
In addition, sodium hydroxide is also used in the production of polycarbonate, super absorbent polymers, zeolites, epoxy resins, sodium phosphate, sodium sulfite and large amounts of sodium salts.
When working with sodium hydroxide, please pay attention to the following short version of safety precautions:
Strong corrosiveness: Sodium hydroxide is highly corrosive and can corrode skin, eyes and clothing. Be sure to wear protective glasses and acid- and alkali-resistant gloves to avoid direct contact.
Dilution and storage: When diluting, the alkali should be poured into water to avoid boiling and splashing. Store in a dry and ventilated warehouse, away from fire and heat sources, protected from moisture and rain, and stored separately from flammable or combustible materials and acids.
Personal protection: Wear acid and alkali resistant clothing, protective glasses and acid and alkali resistant gloves when operating. Wear air or oxygen respirator when necessary. Smoking, eating and drinking are prohibited in the workplace.
Emergency treatment: If you accidentally come into contact with sodium hydroxide, rinse immediately with plenty of water and then apply boric acid solution. If you feel unwell, seek medical attention immediately.
