Sodium hypochlorite solution is an aqueous solution of sodium hypochlorite, which is yellowish, has a very pungent smell and is extremely unstable. It is a chemical product often used in the chemical industry. Mainly used for bleaching paper pulp and textiles (such as cloth, towel, undershirt, etc.). ), chemical fiber, starch. The soap industry is used as a bleaching agent for oils and fats. The chemical industry is used to produce hydrazine hydrate, monochloramine and dichloramine. It is also used to make chlorinators for cobalt and nickel. Used as water purifier, bactericide and disinfectant in water treatment. The dye industry is used to make sapphire sulfide. Organic industry is used to make chloropicrin, and hydrated calcium carbide is used to make acetylene cleaner. Agriculture and animal husbandry are used as disinfectants and deodorants for vegetables, fruits, farms and barns. Food-grade products are used for disinfection of drinking water, fruits and vegetables, and sterilization of food manufacturing equipment and utensils.
Sodium hypochlorite is sodium hypochlorite. Hypochloric acid produced by the reaction of sodium hypochlorite with carbon dioxide is the effective component of bleaching agent. The national mandatory standard "sodium hypochlorite" (GB19106-2013) came into effect on 20 14 12 1. Replace GB 19 106-2003. The general requirements of sodium hypochlorite solution are specified. GB 25574-20 10 "National Food Safety Standard Food Additive Sodium Hypochlorite" was formulated and promulgated by the Ministry of Health, which stipulated the requirements of sodium hypochlorite as a food additive, and sodium hypochlorite used as a food additive must meet the requirements of this standard.
Precautions for use:
1. Don't apply pressure during irrigation, and don't block the root canal with the needle, so as to avoid the solution exceeding the apical foramen and damaging the tissues around the apical. In order to make the liquid medicine reach the root canal at the apex 1/3, it should be used after the root canal is fully prepared and unobstructed.
2. It should be freshly prepared, protected from light, insulated and sealed.
3. When the concentration is high, it will stimulate the mucosa.
Precautions for operation: closed operation and comprehensive ventilation. Operators must be specially trained and strictly abide by the operating procedures. Operators are advised to wear direct gas masks (half masks), chemical safety glasses, anti-corrosion work clothes and rubber gloves. Prevent the steam in the workplace from leaking into the air. Avoid contact with acids. When handling, handle with care to prevent the packaging and containers from being damaged. Equipped with leakage emergency treatment equipment. Empty containers may leave harmful substances behind.
Precautions for storage: Store in a cool and ventilated warehouse. Stay away from fire and heat sources. The reservoir temperature should not exceed 30℃. It should be stored separately from acid and should not be mixed. The storage area should be equipped with emergency response equipment for leakage and suitable accommodation materials.
