Flake soda is a white, moisture-absorbing solid with strong corrosiveness. It is easily soluble in water and forms an alkaline solution. Flake alkali is a strong base with strong neutralizing ability, so it acts as a catalyst in many chemical reactions.
The preparation of flake alkali is mainly through the electrolysis of salt water solution to generate hydrogen and chlorine, and then chlorine gas is introduced into water to generate hydrochloric acid and hypochlorite. In this process, sodium hydroxide is separated as a by-product, and after evaporation, crystallization, and other steps, flake alkali is obtained.
Flake soda has a wide range of applications in the chemical industry, such as synthetic rubber, synthetic fibers, plastics, pharmaceuticals, pesticides, dyes, oils and other products in the manufacturing process.
In the light industry, flake alkali is used to make products such as paper, soap, synthetic detergents, etc. In the textile industry, flake alkali is used as a desizing agent, a cooking agent and a mercerizing agent for cotton cloth. In the field of environmental protection, flake soda can be used for the treatment and purification of wastewater.
Since flake alkali is highly corrosive, special attention is required when using it. First of all, it is necessary to avoid contact and inhalation of flake alkali dust;Secondly, do not contact the flake alkali with acidic substances to prevent the reaction from producing toxic gases;In addition, wear protective glasses and gloves when using flake alkali to prevent accidental injury.
As an important chemical raw material, flake soda has a wide range of applications in many fields. Although it is highly corrosive, it can be used to its full extent if used correctly. With the continuous development of science and technology, the production and application technology of flake soda will also be continuously improved and perfected, bringing more convenience and benefits to human production and life.
