3. Applications

• Agricultural Application：In agriculture, Zinc sulfate heptahydrate is used as a trace - element fertilizer. Zinc is an essential micronutrient for plants. It plays a crucial role in various physiological processes such as enzyme activation, protein synthesis, and photosynthesis. By supplementing zinc element, it can promote plant growth and development, enhance the resistance of plants to diseases and stresses, and improve crop yield and quality. For example, in the cultivation of fruit trees, applying zinc sulfate heptahydrate can effectively prevent zinc - deficiency diseases like little - leaf disease.
• Medical Application：In the medical field, it is used to prepare zinc - supplement agents. Zinc is an important element for the human body, involved in many biological functions such as immune regulation, wound healing, and DNA synthesis. Zinc deficiency can lead to a series of health problems, including growth retardation, weakened immune function, and skin disorders. Zinc - supplement agents made from zinc sulfate heptahydrate can help people, especially those with zinc deficiency, to replenish zinc and maintain good health.
• Industrial Application：
  • Textile Industry：It can be used as a mordant in dyeing processes, helping to fix dyes on fibers and improve the color fastness of fabrics.
  • Electroplating Industry：Zinc sulfate heptahydrate is used as a raw material for zinc - plating solutions. It provides zinc ions for the electroplating process, enabling the deposition of a uniform and dense zinc coating on the surface of metal parts to improve their corrosion resistance and appearance.

4. Safety Information

• Hazard Statements：May cause skin and eye irritation. Inhalation of dust may irritate the respiratory tract.
• Precautionary Statements：When handling, wear appropriate personal protective equipment, such as gloves and safety goggles. Avoid dust generation during operation. In case of contact with skin or eyes, rinse immediately with plenty of water. If inhalation occurs, move to fresh air and seek medical advice if necessary.
