The types of magnesium chloride can be classified from multiple dimensions. Firstly, in terms of grade, it can be divided into industrial grade magnesium chloride and food grade magnesium chloride. Next, in terms of content, there are anhydrous magnesium chloride and hexahydrate magnesium chloride. Anhydrous magnesium chloride is magnesium chloride without crystal water, while hexahydrate magnesium chloride is magnesium chloride with six crystal waters. From the appearance and shape, magnesium chloride comes in various forms such as magnesium chloride balls, magnesium chloride powder, magnesium chloride halide sheets, magnesium chloride halide essence, magnesium chloride blocks, etc. Among them, white flakes mainly refer to magnesium chloride produced by acid process, with white and transparent color and no impurities in the solution; And Pu Pian is a general term for the production process of large pot boiling, usually milky white or coffee colored. From the perspective of production technology, there are also differences between white film and regular film. White flakes are produced by the acid process, while regular flakes include clean flakes, salt flakes, and through flakes, and are a general term for the large pot boiling process. So, in simple terms, the types of magnesium chloride can be classified from multiple aspects such as grade, content, appearance, shape, and production process. Each type of magnesium chloride has its specific application scenarios and advantages.
