The chemical formula of hydrogen peroxide is hydrogen peroxide. Pure hydrogen peroxide is a light blue viscous liquid. It can be mixed with water in any proportion. It is a strong oxidant. Water solution is commonly called hydrogen peroxide and is a colorless transparent liquid. Its aqueous solution is suitable for medical wound disinfection, environmental disinfection and food disinfection. In general, it will decompose into water and oxygen, but the decomposition rate is extremely slow. The way to speed up the reaction rate is to add catalysts such as manganese dioxide or irradiate it with short wave radiation. The use of hydrogen peroxide can be divided into three kinds: medical, military and industrial. The daily disinfection is medical hydrogen peroxide. Medical hydrogen peroxide can kill intestinal pathogenic bacteria, pyogenic cocci and pathogenic yeasts. It is generally used for surface disinfection of objects. Hydrogen peroxide has oxidation effect, but the concentration of medical hydrogen peroxide is equal to or less than 3%. When wiping the wound surface, there will be burning sensation, the surface will be oxidized to white and bubbles. Clean it with clean water, and restore the original skin color in 3-5 minutes. Chemical industry is used to produce sodium perborate, sodium percarbonate, peracetic acid, sodium chlorite, thiourea peroxide and other raw materials, tartaric acid, vitamins and other oxidants. The pharmaceutical industry is used as a bactericide, disinfectant, and oxidant for the production of thiram insecticide and 40L antimicrobial agent. The printing and dyeing industry is used as bleaching agent for cotton fabrics, and the dyeing of cotton fabrics with VAT dyes. It is used to remove iron and other heavy metals in the production of metal salts or other compounds. It can also be used in electroplating bath to remove inorganic impurities and improve the quality of plating parts. It is also used for bleaching wool, raw silk, ivory, pulp, fat, etc. High concentration of hydrogen peroxide can be used as rocket power combustion aids. Civil use: to deal with the odor of kitchen sewer, buy hydrogen peroxide, add water and laundry powder to the pharmacy and pour it into the sewer to decontaminate, disinfect and sterilize; 3% hydrogen peroxide (medical grade) can be used for wound disinfection;

Hydrogen peroxide (hydrogen peroxide) (industrial grade, food grade, electronic grade, chemical reagent grade)

_Molecular formula: H_2O_2

Quality Standard: Industrial Grade: GB 1616-2003 Food Grade: Q/ZCHG05-2004 Chemical Reagent Grade: GB/T6684-2002

Appearance: Colorless transparent liquid

Packing: 25KG/30KG polyethylene drum or stainless steel tank.

Usage: It is an important oxidant, bleaching agent, disinfectant and dechlorination agent. Mainly used for cotton and other fabric bleaching; pulp bleaching and deinking; organic and inorganic peroxide manufacturing; organic synthesis and polymer synthesis; treatment of toxic wastewater; bleaching agents, oxidants, starch denaturants, preservatives and paper-plastic aseptic packaging materials in the food industry before packaging sterilization and aseptic filling machine production line; electronics industry is mainly used. It can be used for corrosion on the surface of metal-containing parts of integrated circuit board and cleaning of silicon crystal and integrated circuit.

_Preservation Period: Reduction of H_2O_2 content within 6 months is not more than 4%.

_Hazardous characteristics: Hydrogen peroxide is a kind of 5.1 oxidant with strong oxidation. Although it is non-flammable, the oxygen generated during decomposition can strongly support combustion. It will cause explosion when it contacts with flammable and organic substances, and it will be in danger of combustion and explosion when it strikes, rubs and vibrates. Hydrogen peroxide with a concentration greater than 40% is corrosive.

Fire extinguishing methods: Fire fighters must wear full body fire and anti-virus clothing, move the containers from the fire site to the open space as far as possible, and spray water to cool the containers in the fire site until the end of the fire extinguishing. Containers in the fire site must be evacuated immediately if they have discolored or sound from safety relief devices.

Fire extinguisher: plenty of water.

Transportation and storage precautions: Transportation and storage should prevent direct sunlight or heat, should be stored in a cool, clean, ventilated warehouse, away from fire and heat sources, warehouse temperature should not exceed 40 degrees Celsius. Keep the container sealed, the container bucket mouth upward, can not be inverted and fall, should be separated from flammable or combustible, reducing agent, alkali, metal powder and other storage, avoid contact with paper, wood, etc. When handling, Li should be lightly loaded and unloaded to prevent damage to packaging and containers. If it is found that the package is damaged and leaked, it should be cleaned and replaced in time, and the leachate should be washed with water. There should be sufficient water source and fire hose spray device, and fire and explosion proof electronic devices and devices should be used. (We can also supply electronic and chemical reagent-grade hydrogen peroxide according to customer's needs)
