Key Types and Characteristics
Industrial grade salt is available in various forms, including rock salt, solar salt, and vacuum-evaporated salt. Rock salt is commonly used in de-icing and water softening, while solar salt is favored in chemical manufacturing and food preservation. Vacuum-evaporated salt, with high purity, is preferred in pharmaceutical and industrial applications requiring minimal impurities.
The primary characteristics of industrial grade salt include uniform particle size, high sodium chloride content, and low levels of insoluble matter. These properties ensure consistent performance in chemical reactions, water treatment processes, and other industrial applications.
Major Applications
Industrial grade salt is a critical component in multiple sectors. In chemical manufacturing, it is used for producing chlorine, caustic soda, and soda ash. Water treatment plants utilize it to regenerate ion-exchange resins and remove impurities from water.
The food processing sector also relies on industrial salt for preservation, fermentation, and flavoring, while road maintenance departments use it extensively for winter de-icing. Additionally, it serves as a raw material in textile, leather, and soap production, highlighting its diverse industrial relevance.
