Manufacturing Method of Zinc Fluorosilicate
Zinc Fluorosilicate is an important inorganic chemical, widely used in ceramics, glass, metallurgy, electronics and other fields. This article will introduce the manufacturing method of zinc fluosilicate, including raw material preparation, reaction process, post-treatment and precautions.
I. Raw material preparation
1. Fluorosilicic acid: Fluorosilicic acid is the main raw material for manufacturing zinc fluorosilicate, which is generally produced by the reaction of fluorite and sulfuric acid.
2. Zinc salt: Zinc salt can be zinc sulfate, zinc oxide, etc., as the raw material to provide zinc ions.
2. Reaction process
The manufacture of zinc fluosilicate is mainly realized by the reaction between fluosilicic acid and zinc salt, the specific steps are as follows:
1. Add fluosilicic acid into the reactor and turn on the stirring.
2. Slowly add the zinc salt while controlling the reaction temperature to avoid local overheating.
3. Hydrogen will be generated during the reaction, which needs to be discharged through ventilation equipment.
4. After the reaction is completed, filter, wash and dry to get zinc fluosilicate product.
3. Post-processing
1. Product packaging: Pack the zinc fluosilicate product into woven bag or carton lined with plastic bag and keep it sealed.
2. Waste disposal: Waste generated during the reaction process should be properly disposed of in accordance with environmental protection requirements to avoid pollution of the environment.
4. Precautions
1. Operators should wear protective gear and avoid direct contact with zinc fluosilicate.
2. Temperature should be strictly controlled during the reaction process to avoid safety accidents caused by excessive temperature.
3. The production site should be equipped with fire extinguishing equipment as a precaution.
4. Regularly check and maintain the production equipment to ensure normal operation.
In short, the manufacture of zinc fluosilicate requires strict compliance with relevant operating procedures and safety requirements to ensure product quality and production safety. The manufacturing method introduced in this article can provide certain reference and guidance for the production of zinc fluosilicate in the field of raw materials for chemical production.
