Magnesium hydroxide is a non-toxic, harmless and safe green inorganic chemical. It has good application prospects in polymer flame retardant, wastewater treatment and flue gas desulfurization.
Physical and chemical methods for the preparation of magnesium hydroxide
Physical method : using natural brucite as raw material, mechanically preparing magnesium hydroxide of different particle sizes.
Chemical method : the use of magnesium-containing raw materials, the preparation of magnesium hydroxide by chemical reaction, is divided into precipitation method, hydration method and other methods. Among them, the hydration method, that is, magnesium oxide and water react to form magnesium hydroxide, which is a method which is widely used.
At present, more and more domestic and foreign scholars have carried out a series of research work on the kinetics and mechanism of magnesium oxide hydration.
Such as the experimental method in a document above :
When determining the CAA value during the hydration of magnesium oxide, the sample should be thermostated to 30 ° C in a water bath, and then placed on a constant temperature magnetic stirrer for stirring; in the orthogonal experiment of magnesium oxide hydration, the hydrating agent is heated in a water bath. After setting the temperature, add magnesium oxide and then stir it.
customer feedback
A user of magnesium hydration research in a university told us that in the process of oxidizing magnesium oxide hydration, the domestic collector heating magnetic stirrer was used to realize the functions of water bath thermostatic and magnetic stirring required by the experiment. Samples, or two devices, do two samples, but due to the differences in the equipment itself, the consistency of the results cannot be guaranteed.
solution
Now use IKA multi-point magnetic stirring constant temperature water bath ICC basic RO15, bottom with multi-point magnetic stirrer RO15, using magnetic coil technology to provide multi-point consistent noise-free mixing, the technology has the advantage of constant speed, even if the load weight changes, very good It realizes the function of water bath temperature control and multi-site magnetic stirring. It can do 15 samples of constant temperature stirring at one time, which not only improves the experimental efficiency, but also has better parallelism.
