Surface modification treatment of magnesium hydroxide

      It is necessary to carry out surface modification treatment on magnesium hydroxide to improve its compatibility with polymer matrix materials, so that the mechanical properties of the filling material do not decrease, and even improve some of the mechanical properties of the material.

        Magnesium hydroxide is insoluble in water and is a relatively weak alkali, but it is slightly irritating to the eyes, respiratory system, and skin. Therefore, appropriate protection should be taken when using, and gloves or goggles should be worn. In case of accidental contact with eyes, rinse immediately with plenty of water and seek medical attention. There is basically no corrosiveness.
Preparation of magnesium hydroxide: Using dolomite as raw material to produce lightweight magnesium carbonate, it involves digesting dolomite lime to generate a suspension of calcium hydroxide and magnesium hydroxide. The mixture is then carbonized using kiln gas containing carbon dioxide to produce calcium carbonate and magnesium bicarbonate. The difference in solubility between the two is utilized to achieve the separation of calcium and magnesium, and then the magnesium bicarbonate remaining in the solution is pyrolyzed.
       Protective measures, equipment, and emergency response procedures for magnesium hydroxide operators: It is recommended that emergency response personnel wear breathing apparatus, anti-static clothing, and rubber oil resistant gloves. Do not come into contact or cross over leaked materials. All equipment used during homework should be grounded. Cut off the source of leakage as much as possible. Eliminate all ignition sources. Designate a warning zone based on the impact area of liquid flow, steam, or dust diffusion, and evacuate unrelated personnel from crosswind or upwind to a safe area.
        Magnesium hydroxide, as a chemical, is used as a containment and removal method for leaks, as well as the disposal materials used. Minor leaks: Collect the leaked liquid in a sealable container as much as possible. Absorb with sand, activated carbon or other inert materials and transfer to a safe place. Do not flush into the sewer. Large amount of leakage: Build embankments or dig pits for containment. Close the drainage pipeline. Cover with foam to inhibit evaporation. Transfer to a tank truck or dedicated collector using an explosion-proof pump, recycle or transport to a waste disposal site for disposal.
