Application of hydrothermal modification technology in improving the performance of brucite powder

Hydrothermal modification technology is a method of treating materials in a specific high-temperature and high-pressure aqueous solution environment, which has a significant impact on the microstructure, morphology and properties of brucite powder. This article explores the potential impact of hydrothermal modification on brucite powder morphology, particle size, purity, crystallinity, dispersion, surface properties and its application areas, and emphasizes the importance of modification conditions on final product performance.

Brucite powder, as an important inorganic material, is widely used in many fields. Hydrothermal modification technology provides an effective way to improve the performance of brucite powder by simulating the high-temperature and high-pressure aqueous solution environment in natural geological processes.

2. Effect of hydrothermal modification on morphology and particle size of brucite powder

Hydrothermal conditions, especially pH value, temperature, pressure and reaction time, play an important role in regulating the morphology and particle size of brucite powder. By precisely controlling these conditions, brucite products with different morphologies and particle size distributions can be obtained.

3. Improve purity and crystallinity

Hydrothermal treatment promotes the orderly arrangement of crystals in brucite powder, improves its purity and crystallinity, thereby enhancing the thermal and chemical stability of the material.

4. Enhance dispersion

The brucite powder obtained by hydrothermal modification has smaller particle size and more uniform distribution, which helps to improve its dispersion in polymer matrix composites, thereby improving the performance of the composite materials.

5. Surface modification

Hydrothermal treatment can also achieve surface modification of brucite powder, by introducing functional groups or reacting with other substances to change its surface properties and improve compatibility with the polymer matrix.

6. Expansion of application fields

After hydrothermal modification, the physical and chemical properties of brucite powder are improved, making it more widely used in fields such as flame retardants, fillers or reinforcing agents.

Hydrothermal modification technology is an effective means to improve the performance of brucite powder. By adjusting hydrothermal treatment conditions and modifiers, the specific properties of brucite powder can be customized to meet different application needs.
