1. For Paper and textile industry

• Pulp and textile bleaching: Sodium hypochlorite is widely used for bleaching textiles such as pulp, cotton cloth, towels, sweatshirts, and chemical fibers, which can effectively remove pigments and improve whiteness. The process includes rolling, rinsing, and other methods, but the conditions need to be controlled to avoid fiber damage.

Fiber Applicability: Suitable for cotton and viscose cotton blended fabrics, but not recommended for protein fibers such as silk and wool as they may damage the fiber structure.

1. For Soap industry

• Oil bleaching: As a bleaching agent for oil, it ensures the cleanliness of soap making materials and improves product quality.

1. For Chemical raw materials and intermediates

Chemical production: used for synthesizing chemical products such as hydrazine hydrate, monochloramine, and dichloroamine, and also as a chlorinating agent for cobalt and nickel, as well as a raw material for the production of dyes such as sulfur blue.

• Other industrial uses: cleaning agent for acetylene production by calcium carbide hydration, manufacturing of chloropicrin in organic industry, etc.

1. For Water treatment and disinfection

Water purification: Used as a disinfectant and disinfectant in drinking water and sewage treatment to kill bacteria and viruses, ensuring water quality safety.

Wastewater treatment: used as a decolorizer to remove dyes from printing and dyeing wastewater, and to remove ammonia nitrogen through chloramine reaction, improving water quality.

1. For Agriculture and Food Disinfection

Agricultural applications: Used for disinfection of vegetables and fruits, as well as for decontamination and disinfection of breeding farms and livestock houses.

Food industry: Disinfect food processing equipment, utensils, beverages, fruits, etc. to ensure food safety.

1. For Dye industry additives

• Dyeing assistance: As a dyeing aid, it enhances the binding effect between dyes and fibers, and improves dyeing uniformity.

1. For Home and Medical Use

Household cleaning: As a universal bleach, used for cleaning and disinfecting clothing and surfaces.

Medical disinfection: disinfection of medical equipment, wards, and operating rooms, cleaning and disinfection in dental root canal treatment.

precautions

• Process control: It is necessary to strictly control the concentration and contact time to avoid excessive oxidation leading to fiber degradation or release of toxic gases (such as when mixed with acid).

• Environmental friendliness: Compared to traditional bleaching agents, sodium hypochlorite produces fewer by-products, but attention should be paid to its strong oxidizing properties and potential corrosiveness to equipment.

The above applications are based on the bleach strong oxidizing and broad-spectrum bactericidal properties, covering multiple fields such as industry, people’s livelihoods, and environmental protection.
