The preparation of anhydrous magnesium chloride is mainly prepared by two methods of repeated heating, concentration, recrystallization and replacement of titanium metal by magnesium chloride hexahydrate. The former is relatively expensive to prepare, and the prepared anhydrous magnesium chloride still contains a certain amount of alkali metal chloride. In the latter, the content (MgCl2) of the produced anhydrous magnesium chloride can theoretically reach 99%, and does not contain alkali metal salts. Now companies use this as a coagulating blending agent more widely.
Many companies use magnesium oxide to replace anhydrous magnesium chloride produced by replacing titanium metal. However, because some problems were ignored, various problems always appeared.
As a manufacturer of magnesium chloride, we remind cooperating companies to keep these in mind when using magnesium chloride. This type of anhydrous magnesium chloride is an industrial by-product, so the content of magnesium chloride will fluctuate, and its fluctuation value is about 92%-97%. Enterprises purchasing anhydrous magnesium chloride need to analyze and detect the content of magnesium chloride by themselves, otherwise it will cause anti-halogen and frost phenomenon.
Many companies believe that anhydrous magnesium chloride will not form the phenomenon of anti-halogen blooming. In fact, anhydrous magnesium chloride is a highly hygroscopic substance, and it will gain 8% weight after 25 days at a relative humidity of 60% to 70%. Therefore, if anhydrous magnesium chloride with different magnesium chloride content is used, it will affect the percentage concentration of the brine, and then form anti-halogen and frost. Anhydrous magnesium chloride does not overcome the shortcomings of magnesium chloride anti-halogen blooming, and pay attention to the content of magnesium chloride in the anhydrous magnesium chloride. When using it, you must remember to avoid unnecessary losses.
