Ultrasonic assisted hydration method: an efficient technology to improve the dispersibility of magnesium hydroxide

Magnesium hydroxide (Mg(OH)_2), as a multifunctional material, is widely used in many fields such as flame retardancy, medicine, and environmental protection. However, its dispersion problem in practical applications has always been a key factor restricting its performance. Ultrasound-assisted hydration method, as an effective means to improve the dispersion of magnesium hydroxide, has attracted widespread attention from scientific researchers and industry.

Reduce agglomeration

The mechanical vibration and cavitation effect generated by ultrasonic waves can effectively destroy the physical attraction between magnesium hydroxide particles, reduce agglomeration, promote particle separation, and significantly improve its dispersion in the medium. particle refinement

The energy of ultrasound helps to break large particles into smaller particles, increase the specific surface area, and improve the dispersion stability in the liquid medium, thereby enhancing its application effect. Interface modification effect

The local high temperature and high pressure environment generated during ultrasonic treatment can promote the physical and chemical interaction between the particle surface and the dispersion medium, and improve the wettability and dispersibility of the particles.

Ultrasound-assisted hydration can accelerate the reaction between the magnesium hydroxide precursor MgO and water to generate more uniform and smaller magnesium hydroxide particles, which is beneficial to its dispersion in various media. Crystal form and morphology control

By adjusting the ultrasonic conditions, such as frequency, power and action time, the crystal form and morphology of magnesium hydroxide can be precisely controlled, promoting the formation of particles of specific shapes and further improving dispersibility. Optimizing the synergistic effect of dispersants

When dispersants are added during ultrasonic treatment, ultrasound can enhance the interaction between dispersants and particles, improve the dispersion effect, and especially improve compatibility and flame retardancy in applications in polymer matrices. Ultrasonic-assisted hydration effectively improves the dispersibility of magnesium hydroxide by precisely controlling ultrasonic parameters, making it exhibit better performance in multiple fields such as polymer composites and water treatment. With the continuous maturity of technology and the deepening of its application, it is expected to provide more possibilities for the application of magnesium hydroxide and promote technological progress and industrial upgrading in related industries.
