Anhydrous calcium chloride desiccant and anhydrous copper sulfate are used, but anhydrous calcium chloride and anhydrous copper sulfate desiccant are neutral, that is, desiccant without reaction of acid or alkaline substances, so its role is only water, not absorbing impurities. Nitrogen drying is to remove water vapor, gas and other impurities in nitrogen, which must be removed by other means. There are also acid or alkaline desiccants, such as sodium hydroxide is an alkaline desiccant, which can remove nitrogen and other water vapor, but also discharge carbon dioxide and other nitrogen acid gas.
Therefore, when removing water vapor, mixed desiccant is often used, for example, alkali lime is a mixture of anhydrous calcium chloride and sodium hydroxide, which can remove acid impurity gas while removing water vapor.
The actual use of anhydrous calcium chloride or many industries, and many industries, so if you don't understand the role of anhydrous calcium chloride, so you can see that some need to often use desiccant industry, basically need to use such products. Industry and laboratory often need to use anhydrous calcium chloride as desiccant. In fact, it has strong practicability and very favorable price. In fact, many industries are buying anhydrous calcium chloride in batches, which can not only ensure the drying effect, but also save a lot of investment costs.
This kind of product can be used as desiccant. The desiccant industry basically needs to use it. It will use anhydrous calcium chloride and anhydrous calcium chloride to dry. It can absorb a certain amount of water to keep the room and product dry. It can ensure the accuracy in chemical experiments. However, such products are not all dry. If low alcohol and ammonia can not use this desiccant, other dry products need to be used. There are many kinds of desiccants, which can't be chosen blindly.
Of course, many people may think that anhydrous calcium chloride has many or medicinal effects. In fact, this is mainly because calcium chloride can help certain quality diseases, such as low calcium urticaria, taxation, or the occurrence of magnesium salt poisoning. It can also be used in a comprehensive way. At present, the rare osteochondrosis and rickets can also be treated with anhydrous calcium chloride. But this effect is generally in the medical field, a large number of use of anhydrous calcium chloride in industry or more.
