[Chemical Knowledge]：Properties, uses, upstream and downstream raw materials, storage methods of zinc fluorosilicate, uses of fluorosilicate

Properties of zinc fluosilicate

Zinc fluosilicate (zinc fluorosilicate), the chemical formula ZnSiF · xH₂ O, is an inorganic compound, usually in the form of a hydrate. Its appearance is colorless or white crystal, soluble in water, and solubility increases with the increase of temperature. In aqueous solution, it will be partly dissociated to form fluoride ions (Fover) and silicon fluoride ions (SiF²²²), which shows strong corrosiveness. Because of its water solubility and chemical stability, zinc fluosilicate is widely used in many fields.

Zinc fluosilicate uses

Construction and Building Materials

Zinc fluosilicate is used in the construction industry as a waterproofing additive for cement and concrete. It can improve the anti-permeability of concrete and prolong the service life of buildings. Zinc fluorosilicate can also be used for anti-corrosion treatment of building materials to prevent damage to materials due to chemical attack.

electroplating industry

In the electroplating industry, zinc fluorosilicate is used as an additive for galvanizing. It can improve the smoothness and adhesion of the coating and improve the corrosion resistance of the coating. The application of zinc fluorosilicate makes the electroplating process more efficient and reduces the production cost.

Agriculture and Horticulture

Zinc fluosilicate is used in agriculture and horticulture as a micronutrient fertilizer. Zinc is one of the essential trace elements for plant growth. Zinc ion in zinc fluosilicate can be absorbed and utilized by plants to promote plant growth and improve crop yield and quality.

Zinc fluosilicate upstream and downstream raw materials

Upstream raw materials

The production of zinc fluosilicate mainly depends on two raw materials, fluosilicic acid (H₂ SiFlem) and zinc oxide (ZnO). Fluorosilicic acid is usually a by-product of the reaction of hydrogen fluoride (HF) with silicates, mainly from the by-product of the phosphate fertilizer production process. Zinc oxide is produced by smelting zinc ore or secondary recovery of zinc. The supply of these raw materials directly affects the production cost and market supply of zinc fluorosilicate.

Downstream Products

The downstream products of zinc fluosilicate mainly include various anti-corrosion coatings, building material additives, electroplating solutions and agricultural fertilizers. They are widely used in many fields, so the market demand for zinc fluorosilicate is large. With the advancement of technology and the expansion of application fields, the downstream product types and application ranges of zinc fluorosilicate are also increasing.

Zinc fluosilicate storage method

Storage Environment

Zinc fluosilicate is corrosive and therefore requires special care during storage. It should be stored in a dry, well-ventilated warehouse, away from direct sunlight and humidity. The storage temperature should be kept below 30°C to prevent hydrolysis or other chemical changes.

Packaging requirements

Because zinc fluosilicate is easily hygroscopic and corrosive, its packaging materials need to have good moisture resistance and corrosion resistance. Plastic drums, plastic bags or corrosion-resistant metal containers are usually used for packaging, and the chemical name, main ingredients and related warning signs are marked on the outer packaging to ensure safety and reliability during transportation and storage.

Safety Precautions

When storing and transporting zinc fluorosilicate, care should be taken to prevent leakage and contamination. Wear protective gloves, goggles and protective clothing during handling to avoid direct contact with skin and eyes. In case of leakage, dry sand or other inert materials shall be used for covering and cleaning in time to prevent harm to the environment.

Market Analysis and Prospects

With the recovery of the global economy and the acceleration of industrialization, the market demand for zinc fluosilicate will continue to grow. Especially in the fields of construction, electroplating and agriculture, the demand for high-performance additives and modifiers is increasing, which provides a broad market prospect for zinc fluorosilicate.

The increasingly stringent environmental regulations also put forward higher requirements for the production and application of zinc fluosilicate. In the future, manufacturers need to strengthen the research and development and application of environmental protection technologies to improve product quality and production efficiency to meet the dual needs of the market and supervision.

Conclusion

Zinc fluosilicate plays an important role in many industries due to its unique chemical properties and wide range of applications. Through the detailed analysis of its properties, uses, upstream and downstream raw materials and storage methods, it can be seen that zinc fluosilicate has great potential for development in the future. With the advancement of technology and changes in market demand, the application range of zinc fluorosilicate will be further expanded, providing strong support for the development of related industries.
