Fluoride Silicon Acid Magnesium

Magnesium fluorosilicate has a wide range of uses. In the field of construction, it is often used as a waterproof agent. The material of masonry, applied with magnesium fluorosilicate solution, can penetrate into the pores, and then materialize into insoluble salts, dense pores, increase its waterproof ability, so that the building is not afraid of water immersion and has durability.
In the ceramic industry, it also has its functions. It can be used as a flux to reduce the melting point of the ceramic body. When firing, it helps the raw materials to melt, making the body dense and solid, and improving its mechanical properties and surface quality. The glaze surface is smoother and shiny.
Furthermore, in the field of wood preservation, magnesium fluorosilicate also has strengths. With its treatment of wood, it can penetrate between wood fibers, inhibit the growth of fungi and pests, protect wood from erosion, prolong its service life, and protect wooden objects such as buildings and furniture from damage for a long time.
In the textile industry, magnesium fluorosilicate can be used as a fabric fire retardant. When the fabric is treated with it, it can generate a protective film for heat insulation in case of fire, slow down the burning speed, prevent the spread of fire, and increase the fire safety of the fabric. It is of great significance in both public spaces and home fabrics.
In the leather tanning process, it also plays a role. It can assist the leather tanning process, tightly combine the leather fibers, enhance the strength and toughness of the leather, and have a certain anti-corrosion and anti-bacterial effect, making leather products durable.

Magnesium fluorosilicate, which is a white crystal or powder, odorless. It is easily soluble in water, and the aqueous solution is acidic and insoluble in alcohol. When heated, it decomposes and releases toxic fluoride fumes.
This substance is corrosive and harmful to the human body. If it is accidentally touched with the skin, it will cause skin burns; if it enters the eyes, it can damage the eye tissue. Inhalation of its dust or smoke can irritate the respiratory tract, causing symptoms such as cough and breathing difficulties. Long-term exposure may also damage bones and teeth.
Widely used in industry, it is often used as a concrete hardener to enhance the hardness and wear resistance of concrete; used as a water repellent in the textile industry; used in the leather industry for leather tanning.
Use and store with extreme caution. Store in a cool, dry and well-ventilated place, away from fire and heat sources, and avoid contact with acids and alkalis. When using, operators must take protective measures, such as wearing protective glasses, gloves and gas masks, to prevent contact and inhalation. In case of leakage, personnel from the contaminated area should be quickly evacuated to a safe area for isolation and strict access restrictions. Emergency responders should wear self-priming filter dust masks and anti-acid and alkali work clothes. Do not let leaks come into contact with organic matter, reducing agents and flammable substances. In the event of a small leak, a clean shovel can be used to collect it in a dry, clean, covered container. In the event of a large leak, a dike or pit should be built for containment, and a pump should be transferred to a tanker or a special collector for recycling or transportation to a waste disposal site.

The method of making magnesium fluorosilicate has existed in ancient times, and is described in detail below.
The first quarried silica and fluorite are used as raw materials. Silica is pure and has a high silicon content. Fluorite should also be selected, and the quality should be high. Mix the two in an appropriate ratio and place them in a special kiln. The kiln needs to be calcined at high temperature. This process needs to be precisely controlled by temperature and the heat is appropriate. At high temperature, silica and fluorite react chemically to form gaseous silicon fluoride.
The second time, the silicon fluoride is absorbed by water. Prepare a container with an appropriate amount of water, so that the gaseous silicon fluoride slowly passes into the water. When the fluorinated silicon encounters water, it combines with it to form a fluorosilicic acid solution. This solution needs to be finely filtered to remove its impurities and keep it pure. After
, take magnesium oxide or magnesium carbonate and slowly add it to the obtained fluorosilicic acid solution. When the two meet, they react, and through a series of chemical reactions, magnesium fluorosilicate is formed. During the reaction process, stirring is required to make the reaction sufficient. After the reaction is completed, the resulting mixture is evaporated and concentrated. During evaporation, the heat and time need to be accurately controlled, so that the water is gradually lost, and the concentration of magnesium fluorosilicate gradually increases.
After concentration, the method of cooling and crystallization is carried out. The concentrate is placed in a suitable environment for natural cooling, and the magnesium fluorosilicate crystallizes and precipitates. After centrifugation, the crystallization is separated from the mother liquor. The resulting crystals are crude magnesium fluorosilicate.
The crude product still needs to be refined. Dissolve the crude magnesium fluorosilicate with an appropriate amount of water, filter it again, and further remove impurities. Then repeat the steps of evaporation concentration, cooling crystallization, centrifugal separation, etc., and repeat several times until a pure magnesium fluorosilicate product is obtained. In this way, there is a method for preparing magnesium fluorosilicate.

Magnesium fluorosilicate is commonly used in chemical industry. During storage and transportation, many matters need careful attention.
First of all, storage, this substance should be placed in a cool, dry and well ventilated place. Because of its fear of moisture, if it is in a humid place, it is easy to absorb moisture and deteriorate. The temperature of the warehouse should also be reasonably controlled and should not be too high to prevent its chemical properties from changing. And it should be placed separately from acids, alkalis and other substances, because magnesium fluorosilicate and acid and alkali can react chemically, and mixed storage is prone to danger. In the storage area, it is also necessary to be equipped with corresponding leakage emergency treatment equipment and suitable containment materials for emergencies.
As for transportation, the transportation vehicle must be clean and free of other residues that may react with it. When loading, it should be handled lightly and handled lightly, and must not be operated brutally to prevent the leakage of magnesium fluorosilicate due to damaged packaging. During transportation, it must be protected from exposure to the sun, rain, and avoid high temperatures. If the transportation environment temperature is too high, or the properties of magnesium fluorosilicate may change, or even cause safety accidents. Transport personnel should also be familiar with the characteristics of magnesium fluorosilicate and emergency treatment methods. In case of leakage and other conditions, they can be disposed of quickly and properly to reduce harm. In short, the storage and transportation of magnesium fluorosilicate must be carried out with caution and in accordance with its characteristics, so that security is safe.

Magnesium fluorosilicate is also a chemical substance. It is involved in the environment and human health and cannot be ignored.
First talk about the impact of the environment. If magnesium fluorosilicate is released in nature, it may cause water pollution. The fluoride it contains enters rivers, lakes and seas, and can harm aquatic organisms. Fluoride accumulates in the bottom of the water, gradually changing the water quality, causing the acid and alkali of the water body to be unbalanced, and plankton, fish and shrimp are all affected by it. In the soil, if magnesium fluorosilicate seeps into it, it can cause soil fluoride enrichment. This can change the physicochemical properties of the soil, hinder the uptake of nutrients and water by plant roots, cause poor plant growth, and wither and die when it is heavy. And it may expand the area of pollution with rainwater runoff, endangering the surrounding ecology.
As for human health, magnesium fluorosilicate also has an impact. If a person encounters it through breathing, diet, skin contact, etc., fluoride ions in magnesium fluorosilicate can enter the human body. Although appropriate fluoride is beneficial to the health of teeth and bones, excessive amounts are extremely harmful. Inhaled through the respiratory tract, it can stab the throat, trachea, cause cough, asthma, and even respiratory disorders. Oral ingestion can damage the gastrointestinal mucosa, causing nausea, vomiting, abdominal pain, diarrhea, etc. Excessive intake for a long time, fluoride accumulated in the body, can cause fluorosis, fluorosis in teeth, osteoporosis, osteoporosis, joint pain and stiffness, mobility problems, and severe cases can be disabled.
Therefore, magnesium fluorosilicate has potential harm to the environment and human health. In its production, use, and disposal, great care should be taken to minimize its adverse effects on the environment and people.
