[Chemical Knowledge]：The nature, use, upstream and downstream raw materials, storage methods, magnesium fluorosilicate is not dangerous goods.

Magnesium fluosilicate properties

Magnesium fluosilicate (Magnesium Fluorosilicate), the chemical formula MgSiF · 6H₂ O, is a colorless to white crystal or powder with strong hygroscopicity. It is soluble in water, and its solution is acidic, difficult to dissolve in ethanol. Its melting point is around 100°C and its decomposition temperature is around 350°C. The chemical properties of magnesium fluorosilicate are relatively stable, but it will decompose to form magnesium fluoride and silicon dioxide under high temperature conditions. Its chemical reaction activity is mainly reflected in the neutralization reaction with alkali, which can generate magnesium fluoride and silicate.

Magnesium fluosilicate uses

wood preservative

Magnesium fluosilicate is widely used in the field of wood preservation. Because it can effectively prevent the invasion of fungi and insects, it is often used as a wood treatment agent to extend the service life of wood. Its high-efficiency anti-corrosion performance benefits from its ability to penetrate into the wood to form a protective film to prevent the entry of moisture and harmful substances.

Building Materials Additives

In the field of building materials, magnesium fluorosilicate is often used as an additive for cement and concrete. It can improve the strength and durability of cement and concrete, and reduce the weathering and corrosion of materials. Magnesium fluorosilicate can also enhance the permeability and wear resistance of concrete, and is suitable for construction projects in various complex environments.

chemical industry

Magnesium fluorosilicate is also widely used in the chemical industry, especially in the production of magnesium compounds. It can be used as a raw material for the production of magnesium salts, such as magnesium fluoride, magnesium silicate, etc. Magnesium fluorosilicate can also be used as a catalyst or reaction medium to participate in a variety of chemical reactions and improve reaction efficiency and product quality.

Upstream raw materials

Hydrogen fluoride

The production of magnesium fluorosilicate requires hydrogen fluoride (HF) as one of the main raw materials. Hydrogen fluoride is a highly corrosive gas, which is widely used in chemical, refrigerant and aluminum processing industries. The main ways to obtain it are the chemical reaction of mineral fluorite (CaF₂) and the recycling of fluoride waste.

Silicate

Another important upstream raw material is silicates (SiO-H4). Silicate is one of the most common minerals in the earth's crust and can be extracted from various silicate minerals. Its role in the production of magnesium fluorosilicate is to provide silicon elements and participate in the chemical reaction of generating fluorosilicate.

magnesium compound

Magnesium compounds, such as magnesium oxide (MgO) or magnesium hydroxide (Mg(OH)₂), are another key raw material for the production of magnesium fluosilicate. Magnesium compounds can be extracted from magnesite or obtained by chemical synthesis methods. Its main function is to provide magnesium element, and form stable magnesium fluorosilicate crystals with fluorosilicic acid.

Downstream Products and Applications

Construction industry

The downstream products of magnesium fluorosilicate mainly include waterproof materials, enhancers and preservatives required by the construction industry. These products are widely used in concrete structures, tunnels, bridges and other projects to improve the service life and safety of buildings.

agricultural field

In agriculture, magnesium fluosilicate is used as an additive for soil amendments and pesticides. Its main function is to regulate soil pH, improve soil structure and promote plant growth. Magnesium fluosilicate can also enhance the stability and effectiveness of pesticides and improve the yield and quality of crops.

Water treatment

Magnesium fluosilicate is also used in water treatment processes, particularly as a precipitant and disinfectant. It can effectively remove suspended solids and harmful microorganisms in the water and purify the water. It is widely used in industrial wastewater treatment, municipal sewage treatment and drinking water purification and other fields.

storage method

sealed preservation

Since magnesium fluorosilicate has strong hygroscopicity, it is necessary to use a sealed storage method to prevent it from absorbing moisture in the air and affecting the quality. Plastic bags, plastic drums or glass bottles are usually used for sealed packaging to ensure their dry state.

Dry environment

Magnesium fluosilicate should be stored in a dry, cool and well-ventilated environment, away from direct sunlight and high temperatures. High temperatures can cause the decomposition of magnesium fluosilicate, produce harmful gases, and affect storage safety and product performance. Therefore, the warehouse should maintain appropriate temperature and humidity to avoid adverse effects of environmental factors.

Fire prevention and explosion protection

Although magnesium fluorosilicate itself is not flammable, it may decompose under high temperature conditions to produce flammable gases. Therefore, the necessary fire and explosion-proof measures should be taken during storage to avoid the proximity of fire and heat sources. The warehouse should be equipped with fire fighting equipment, such as fire extinguishers, fire hoses, etc. to deal with sudden fires.

Safe handling

Protective measures

When handling magnesium fluosilicate, wear appropriate personal protective equipment such as gloves, goggles and masks to avoid contact with skin and eyes. The solution is corrosive and may cause harm to the human body, so it is necessary to strictly follow the operating procedures to ensure safety.

emergency treatment

In case of leakage, emergency treatment measures shall be taken in time. Isolate the leak area to prevent access. Absorption and collection is then carried out using a suitable adsorbent material, such as sand, soil or adsorbent pads. The collected magnesium fluosilicate waste shall be treated in accordance with hazardous waste treatment regulations to avoid environmental pollution.

Magnesium fluosilicate is a widely used chemical, involving wood preservation, building materials, chemical industry and other fields. Its production involves a variety of upstream raw materials, while its application covers many downstream industries such as construction, agriculture and water treatment. When storing and handling magnesium fluosilicate, special attention should be paid to moisture resistance, fire resistance and safety protection to ensure its stable performance and safe operation.
