Regarding magnesium chloride, we all know that it has granular, flake and powder forms. And its classification is also very many, different classification functions are also different. Although it has also been used in the food industry, magnesium chloride hexahydrate flakes is a chemical industrial product after all. When using it, we must pay attention to the dosage to ensure our health.
The color of magnesium chloride hexahydrate flakes is generally white and yellowish brown. Magnesium chloride hexahydrate flakes can be made into desiccant in industry, which can dry nitrogen, oxygen, sulfur dioxide and other gases. And because of its active chemical properties, it can also be used as a dehydrating agent for alcohols, esters and other substances.
It can also be used as a road snow melting agent in winter, because it is very corrosive to vehicles after melting, so it is widely used in the snow melting agent industry. Of course, in the food industry, magnesium chloride hexahydrate flakes can also act as a desiccant, but because magnesium chloride hexahydrate flakes are chemically active, its success probability is significantly lower than that of calcium chloride desiccant, which is relatively high in terms of packaging and cost. You can also use magnesium chloride aqueous solution to make tofu or as a food additive.
Magnesium chloride is a white crystal at room temperature, which is not only susceptible to moisture, but also soluble in water and ethanol. So not only calcium chloride can be made into desiccant, magnesium chloride hexahydrate flakes can also be made into desiccant.
Although the water absorption effect is not as good as calcium chloride, the desiccant made from magnesium chloride hexahydrate flakes also has its unique charm. Its water absorption is much stronger than some silica gel desiccants, and because of the chemical reaction, it will become solid after absorbing water, and the humidity of the sealed area will be reduced, so that the desiccant will not leak due to packaging problems. And magnesium chloride hexahydrate flakes desiccant will not regurgitate the absorbed moisture, causing moisture in the packaging bags of the goods.
Magnesium chloride hexahydrate flakes desiccant can accept a wide range of temperatures, from -20°C to 90°C, it can be dried. Moreover, magnesium chloride is low-toxic, and a small dose is basically non-toxic. The used magnesium chloride desiccant can be treated as general garbage.
However, because the current technology is not mature enough, the success rate of magnesium chloride hexahydrate flakes desiccant is lower than other desiccants, and the price is higher compared with other desiccants. Its strong water absorption is also one of the reasons for the higher price. The current magnesium chloride hexahydrate flakes desiccant is mainly in powder form, and several different powders can be distributed after mixing in proportion. And the output of magnesium chloride hexahydrate flakes desiccant is very low. Many of the above reasons have led to the high price of magnesium chloride hexahydrate flakes desiccant.
