Study on Magnesium Hydroxide Preparation of Magnesium Chloride Dolomite and Its Application
The flame retardant magnesium hydroxide is calcined and digested with brine precipitation to obtain the product magnesium hydroxide,to explore the influence of calcination temperature,concentration of magnesium chloride,aging time,reaction temperature factors on the purity of product magnesium hydroxide.Then the product magnesium hydroxide was characterized by thermal weight difference thermal analysis(TG-DTA),scanning electron microscope(SEM)and X-ray diffraction(XRD).The experimental results show that the calcination temperature is 960 ℃,the concentration of magnesium chloride is 1.0 mol/L,the aging time is 1.5 h,the reaction temperature is 60 ℃,and the magnesium hydroxide products with a purity of 81.29％can be obtained.
