无水氯化钙干燥剂做和无水硫酸铜是用的，但无水氯化钙和无水硫酸铜干燥剂是中性的，即无酸性或碱性物质反应的干燥剂，所以其作用只是水，不吸收杂质。氮气干燥，是为了除去氮气中的水蒸气、气体等杂质，是必须通过其他方式除去的。也有酸性或碱性干燥剂，如氢氧化钠就是一种碱性干燥剂，它在去除氮气等水蒸气的同时，还能排出二氧化碳等氮气中的酸性气体。
　　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.
　　所以在去除水蒸汽的同时，常采用混合干燥剂，如碱石灰就是无水氯化钙和氢氧化钠的混合物，在去除水蒸汽的同时去除其中的酸杂质气体。
　　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.
　　实际使用无水氯化钙或多或行业,和许多行业大量应用,所以如果你不了解无水氯化钙的作用,所以不妨看到一些需要经常使用干燥剂行业,基本上需要使用这样的产品。工业和实验室经常要用无水氯化钙做干燥剂，其实用性较强，价格非常优惠。其实很多行业都是批量购买无水氯化钙，这样既能保证干燥效果，又能节省大量的投资成本。
　　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.

　　这种产品可以用作干燥剂,干燥剂行业基本上都需要使用,将使用无水氯化钙、无水氯化钙干燥的主要作用,能吸收一定量的水,以保持房间和产品干燥,在化学实验中可以确保准确性。但是这样的产品并不都是干燥的，如果是低醇和氨水不能使用这种干燥剂，需要使用其他干燥的产品。干燥剂也有多种，不能盲目选择。
　　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.
　　当然,许多人可能会认为,无水氯化钙的作用或多或药用的作用,事实上,这主要是氯化钙可以帮助一定质量的疾病,如低钙荨麻疹,税收,或镁盐中毒的发生,还可以用于全面。现在比较少见的骨软骨病和佝偻病，也可以用无水氯化钙治疗。但这样的效果一般在医学方面，大量使用无水氯化钙在工业上还是比较多的。
　　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.
