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時，常采用混合干燥劑，如堿石灰就是無水氯化鈣和氫氧化鈉的混合物，在去除水蒸汽的同時去除其中的酸雜質氣體。

　　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.

　　實際使用無水氯化鈣或多或行業,和許多行業大量應用,所以如果你不了解無水氯化鈣的作用,所以不妨看到一些需要經常使用干燥劑行業,基本上需要使用這樣的產品。工業和實驗室經常要用無水氯化鈣做干燥劑，其實用性較強，非常優惠。其實很多行業都是批量購買無水氯化鈣，這樣既能保證干燥效果，又能節省大量的投資成本。

　　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.

　　這種產品可以用作干燥劑,干燥劑行業基本上都需要使用,將使用無水氯化鈣、無水氯化鈣干燥的主要作用,能吸收一定量的水,以保持房間和產品干燥,在化學實驗中可以確保準確性。但是這樣的產品并不都是干燥的，如果是低醇和氨水不能使用這種干燥劑，需要使用其他干燥的產品。干燥劑也有多種，不能盲目選擇。

　　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.

　　當然,許多人可能會認為,無水氯化鈣的作用或多或藥用的作用,事實上,這主要是氯化鈣可以幫助一定質量的疾病,如低鈣蕁麻疹,稅收,或鎂鹽中毒的發生,還可以用于。現在比較少見的骨軟骨病和佝僂病，也可以用無水氯化鈣。但這樣的效果一般在醫學方面，大量使用無水氯化鈣在工業上還是比較多的。

　　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.
