[Sodium perborate (Four Rivers)] in Yao direct chemical sodium perborate (Four Rivers) supply excellent products

Sodium perborate (Four Rivers) [ID: 0048] English name: sodium perborate / sodium peroxyborate Grade: Industrial Grade Content: 98% Origin: Our packing: woven bag CAS No.: 10486-00-7 Molecular formula: NaBO3? 4H2O HS Code: 2840300000 density: 1.73 Weight: 153.88 Appearance: White monoclinic crystalline powder or granules. Soluble in acid, alkali and glycerin, slightly soluble in water, the solution is alkaline (pH value of 10 to 11), an unstable solution, easy release of reactive oxygen species. In the cold and dry air, high purity sodium perborate is more stable. At 40 ℃ or moist air decompose and release oxygen. Was dissolved at 63 ℃ own crystal water when decomposed and formed a sticky solid mass. Above 70 ℃ 3 loses crystal water to form a monohydrate. At higher temperatures, the presence of the free base of the case, easily decomposed. And the role of acid, generating hydrogen peroxide. * When dealing with concentrated, with the release of oxygen and ozone. Is also susceptible to other substances such as lead oxide, manganese dioxide, potassium permanganate, silver nitrate, copper oxide, cobalt oxide, platinum black and the like and catalytic decomposition. Melting point (℃): 63 Boiling point (℃): 130 ~ 150 (-H2O) Solubility: slightly soluble in water. Sodium perborate dissolved in water at 15 ℃, 1.93%, when the dissolution was endothermic reaction, aqueous alkaline. 40 ℃ decompose and release oxygen. Purposes: as oxidants, bleaching agents, fungicides, deodorant, detergents added like. Sodium perborate has a strong bleaching ability, but does not damage the fibers, suitable for protein fibers such as: wool / silk, and long fiber cotton bleaching senior. Is used as a disinfectant and medicine, also be used as mordant, additive detergent builder, deodorizer, the plating solution, analytical reagents, organic synthetic polymeric agents, as well as system toothpaste, cosmetics and the like. Principle: The higher temperature can be released under the nascent oxygen bleaching effect without affecting the fiber itself Packing and storage: lined with two layers of polyethylene plastic bags, plastic bags or barrels packaging. Bag (barrel) net weight 25kg or 50kg. Should be obvious "oxidant" logo on the packaging. Belong to two inorganic oxidants, IMDG Code: 23027. It should be stored in a dry, clean, ventilated warehouse, storage temperature should not exceed 30 ℃, relative humidity should not exceed 75% of the product under damp heat conditions break down easily. Containers must be sealed. Not in the sun exposure to prevent damp caking or thermal decomposition. Not with organics were stored Mixed transportation. Not long storage. When the fire with water, sand and carbon dioxide fire extinguishers to fight the blaze. Hazard Danger: health hazards: upper respiratory tract irritation strong. Oral corrosive digestive tract, can cause gastrointestinal bleeding. The goods eye and skin irritation and corrosive. Long-term exposure can cause loss of appetite, weight loss, vomiting and anemia. Environmental hazards: hazard to the environment, can cause pollution of water bodies. Explosion hazard: This product combustion, irritating. Hazardous characteristics: May explode when heated. In case of moisture gradually decompose. Toxicity protection: After contact with sodium perborate have a sore throat, cough, vomiting, diarrhea, loss of consciousness, skin and conjunctival hyperemia, pain symptoms. Therefore, we should pay attention to protection against dust dispersion, wear protective equipment. Allowed at work eating, drinking or smoking. Accidentally contaminated, immediately left the scene, flush eyes with plenty of water, stripped of contaminated clothing, rinse the body, sent to hospital treatment when necessary. Wearing a protective mask when cleaning filter leak leak, flush with plenty of water.
