Product Usage

Sodium hypochlorite is a highly effective, broad-spectrum strong oxidizing disinfectant. In water treatment, it is widely used for sterilization and disinfection of drinking water, swimming pools, and industrial recirculating water, quickly inactivating bacteria and viruses. In household cleaning, it is the main component of bleach disinfectants (e.g., "84 disinfectant"), used for bleaching and disinfecting surfaces, fabrics, and tableware. In the paper and textile industries, it serves as a bleaching agent for pulp and fabrics. Additionally, it is used in wastewater treatment for the oxidative removal of ammonia nitrogen and harmful substances. Its advantages include low cost and ease of use, but care must be taken due to its corrosiveness and the risk of decomposing to release toxic chlorine gas when in contact with acids.
