WhatsappZinc Chloride Manufacturing process
Zinc Chloride is manufactured through a controlled reaction between suitable zinc raw material and hydrochloric acid, followed by purification, concentration and drying. Process conditions and final testing depend on the required product specification.
Step 1: Raw Material Selection
- Select suitable zinc raw material and hydrochloric acid according to the required quality specifications.
- Check incoming raw materials before starting the manufacturing process.
Step 2: Chemical Reaction and Processing
- React the zinc raw material with hydrochloric acid under controlled process conditions to produce a Zinc Chloride solution.
- Filter and process the solution to remove unwanted impurities.
Step 3: Concentration and Drying
- Concentrate the purified Zinc Chloride solution under controlled conditions.
- Continue processing and drying according to the required final product form and specification.
Step 4: Quality Control and Testing
- Test the finished Zinc Chloride against the applicable product specification.
- Quality parameters may include identification, assay, pH and specified impurities, depending on the required grade.
Step 5: Packaging and Storage
- Pack the finished Zinc Chloride in suitable moisture-resistant packaging.
- Store it in a dry, properly controlled area and protect it from moisture.
