The application of sodium hypochlorite as bleach agent

Dec17,24

Sodium hypochlorite is an inorganic compound with the chemical formula NaClO. It is a strong oxidizing agent that can oxidize pigment molecules, causing them to decompose into soluble inorganic substances, which are then washed away to achieve the bleaching effect. The bleaching principle of sodium hypochlorite is based on its hydrolysis to produce hypochlorous acid (HClO), the amount of hypochlorous acid produced varies with the pH value, usually HClO under alkaline conditions, and Cl2 under acidic conditions.

Bleaching water is also known as bleach, mainly composed of sodium chloride and sodium hypochlorite, also known as bleaching powder. There are two main types of bleach: chlorine bleach and oxygen bleach. Chlorine bleach contains sodium hypochlorite, while oxygen bleach contains hydrogen peroxide or some compounds that release peroxides, such as sodium perborate or sodium percarbonate. Bleach is a new kind of aqueous solution of bleach powder, one of its main components is sodium hypochlorite. It can react reversibly with water to produce hypochlorite, reduce colored substances, and achieve the purpose of bleaching.

The main functions of bleach include bleaching, sterilization and deodorization. It is often used to remove stubborn stains and yellow pigments in clothes, kitchens, bathrooms, etc., so that items can be restored to white. In addition, sodium hypochlorite and other components in bleach have strong oxidation, which can effectively kill bacteria, viruses and fungi, and are often used for environmental disinfection in homes and medical institutions to prevent the spread of infections. Bleach also has a deodorizing function, reducing odors by oxidizing smelly gases and inhibiting bacterial growth. In food processing, bleach can be used to improve the color of food and make it more vivid and attractive. For example, in the production of preserved fruit, starch syrup and other products bleaching treatment, bleach can destroy or inhibit food color formation factors, so that food color fade or avoid Browning. At the same time, some bleach also has antibacterial, antiseptic, antioxidant and other effects, which helps to extend the shelf life of food. ‌

BLUEWAV sodium hypochlorite equipment can produce 2%-15% NACLO, using brine electrolysis technology, raw materials are: 89% purity of salt and standard water; The products are: sodium hypochlorite solution, sodium hydroxide solution and hydrogen, chlorine gas, up to 150TON/DAY.

‌ Sodium hypochlorite is widely used as a bleach agent, mainly including the following aspects ‌ :
1.‌ pulp and textile bleaching ‌ : Sodium hypochlorite is widely used in the bleaching process of pulp and textiles, which can effectively remove impurities and improve the whiteness of products. For example, cloth, towels, undershirts and other textiles can be bleached by sodium hypochlorite ‌. 2.‌ bleaching of chemical fibers and starches ‌ Sodium hypochlorite is also commonly used as a bleaching agent in the production of chemical fibers and starches to ensure the purity and quality ‌.

3.‌ soapmaking industry: In soapmaking industry, sodium hypochlorite is used as a bleaching agent for grease, to help remove impurities in grease and improve the quality of soap ‌.

4.‌ water treatment ‌ : sodium hypochlorite is also used in water treatment, mainly used to remove impurities and microorganisms in water to ensure the safety and cleanliness of water ‌.

‌ Other industrial applications ‌ : In the chemical industry, sodium hypochlorite is also used in the production of hydrazine hydrate, monochloramine, dichloramine and other chemicals; It is used in the dye industry to manufacture sapphire sulfide; It is used in the organic industry for the manufacture of chlorophenic acid ‌.
