Nature
sodium percarbonate is the abbreviation of sodium peroxide, the appearance is white, loose, good mobility of granular or powdery solid, odorless, soluble in water, also known as sodium percarbonate. Solid powder. Hygroscopic. Stable when dry. It is slowly decomposed into carbon dioxide and oxygen in air. In water is rapidly decomposed into sodium bicarbonate and oxygen. In dilute sulfuric acid decomposition, the formation of quantitative hydrogen peroxide. It can be prepared by reacting sodium carbonate with hydrogen peroxide. Used as an oxidizing agent.
Preparation Method
- dry process: production of sodium percarbonate crystals by spraying a hydrogen peroxide solution onto anhydrous sodium carbonate in a fluidized bed with boiling hot air. Because of the simple production process, production process, production of poor product stability, low active oxygen content, rarely used in industry.
- wet method: a small amount of a stabilizer is added to an aqueous hydrogen peroxide solution, the reaction is carried out under a certain temperature condition, and then the reaction rate, drying and separation are carried out to obtain a product. The product produced by this method has good stability and mature technology, and has been widely used in industry.
Use
sodium percarbonate as a new detergent auxiliary, textile and paper bleaching brightening agent, medical oxygen, Disinfection bactericide, fruit preservative, metal cleaning agent, mouth glue cleaner, dye chromogenic agents are widely used in daily chemical industry, washing products industry, food industry, textile industry, medical and health care, etc. Sodium Percarbonate has more ideal bleaching effect in industrial sodium perborate.
Safety
oxidant. GB Class 5.1 51503. UN NO. 2467I IMDG CODE page 5182, Class 5.1 (this rule does not apply to sodium peroxycarbonate hydrate). When there is a fire, it can be suppressed by sand and all kinds of fire extinguishing. Sodium Percarbonate is easy to decompose, dust stimulates the mucosa, so it should avoid light or long time inhalation. After contact with the skin, rinse with water. Wear gloves and dust masks when using or contacting sodium percarbonate in large quantities to protect eyes. Protection Measure; ① should be stored in a cool, dry warehouse, the temperature should be lower than 40 ℃, avoid high temperature, pay attention to moisture. It should be kept away from the fire and heat source, and cannot be stored and mixed with reducing substances. (2) the transport should be sunscreen rain. When loading and unloading should be light to prevent packaging damage. Packed in plastic woven bag or barrel lined with two layers of polyethylene plastic bag, net weight 25kg or 50kg. Should be stored in a cool, dry warehouse. The temperature should be below 40 ℃ to avoid high temperature. Pay attention to moisture, packaging must be sealed. Stay away from heat sources and fire types. Not co-stored with reducing substances. Transport should be protected from rain and sun. When loading and unloading should be light to prevent packaging
