1. Fireproof board.
Magnesium chloride is one of the main raw materials for fireproof boards. Fireproof board is a decorative material with good fire performance, which is widely used in interior decoration and fireproof partitions of public buildings. Magnesium chloride is mixed with magnesium sulfate, perlite and other materials, and can be made into fireproof board after high temperature and high pressure treatment. This kind of fireproof board has excellent fire performance, strong durability, and has a good decorative effect.
2. Cement concrete.
In cement concrete, magnesium chloride can be used as an early strength agent. Early strength agent can improve the early strength of concrete, shorten the hardening time of concrete, and improve construction efficiency. Magnesium chloride is mixed with gypsum, lime and other materials to make early strength agents for the production of concrete. In addition, magnesium chloride can also improve the working properties of concrete, increasing the impermeability and durability of concrete.
3. Artificial stone.
Magnesium chloride also plays an important role in the production of artificial stone. Artificial stone is a decorative material that simulates natural stone, which has the characteristics of hard texture, wear resistance, corrosion resistance, and bright color. Magnesium chloride is mixed with resins, fillers and other materials, and after high-temperature curing, it can be made into various types of artificial stone. This kind of artificial stone not only has a good decorative effect, but also has excellent physical and chemical properties, and is widely used in kitchen countertops, floors, walls and other decorations.
Fourth, mortar and mortar additives.
In mortar and mortar additives, magnesium chloride can also be used as an early strength agent and anti-cracking agent. Early strength agent can improve the early strength of mortar, shorten the hardening time of mortar, and improve construction efficiency. Anti-cracking agents can reduce the cracks of the mortar and improve the durability of the mortar. Magnesium chloride is mixed with gypsum, lime and other materials to make early strength agent and anti-cracking agent, which is used in the production of mortar.
In general, magnesium chloride is widely used in the building materials industry, which can not only improve the performance of building materials, improve construction efficiency, but also improve the decorative effect of building materials. With the development of science and technology, the application of magnesium chloride in the building materials industry will be more extensive and deeper.
