Manufacturing method of industrial zinc carbonate basic
I. INTRODUCTION
Zinc carbonate basic is an important inorganic chemical, which is widely used in the fields of rubber, plastics, ceramics, glass, medicine and food. As an important chemical raw material, the manufacturing method of zinc carbonate basic has attracted much attention. In this paper, a manufacturing method of industrial zinc carbonate basic will be introduced.
II. Material and equipment
1. Material: zinc salt (such as zinc sulfate, zinc chloride, etc.), alkaline absorbent (such as sodium hydroxide, potassium hydroxide, etc.), carbonate (such as sodium carbonate, potassium carbonate, etc.).
2. Equipment: reactor, stirrer, filter, dryer, etc.
3. Manufacturing method
1. Ingredients: add zinc salt, alkaline absorbent and carbonate ingredients into the reactor according to a certain proportion.
2. Stirring reaction: Turn on the stirrer to make the materials in the reactor fully mixed, and carry out the reaction to generate alkaline zinc carbonate under appropriate temperature and pH conditions.
3. Filtering and washing: After the reaction, the generated zinc carbonate base is separated from the mother liquor through a filter, and then washed with water to neutral.
4. Drying: Put the washed zinc carbonate into a drier and dry it to constant weight under appropriate temperature.
5. Crushing and packaging: Crush the dried zinc carbonate basic, and then pack according to the requirements.
4. Precautions
1. Control the reaction temperature and pH value: the reaction temperature and pH value have an important influence on the generation and properties of zinc carbonate basic, and need to be strictly controlled.
2. Wash to neutral: In order to ensure product quality, zinc carbonate base needs to be washed to neutral to avoid the influence of residual alkaline or acidic substances on the product properties.
3. Drying temperature and time: Drying temperature and time also have some influence on the properties of zinc carbonate basic, and need to be adjusted appropriately according to product requirements.
V. Conclusion
Through the above steps, we can manufacture industrial zinc carbonate basic that meets the requirements. This manufacturing method has the advantages of easy operation, high production efficiency and stable product quality, which can be widely used in the field of raw materials for chemical production.
