Anhydrous calcium chloride is a commonly used desiccant, which can be used to absorb moisture in the air and keep the environment dry. When using anhydrous calcium chloride for drying, there are some precautions and techniques that need to be followed to ensure the drying effect and safe use. Let's find out the secret of drying!

1. Choose the right amount of anhydrous calcium chloride
Before using anhydrous calcium chloride for drying, you need to choose the right amount of anhydrous calcium chloride according to the size and humidity of the dried item. Generally speaking, each kilogram of anhydrous calcium chloride can absorb about 0.6 liters of water, but the specific amount needs to be adjusted according to the situation. Using too much anhydrous calcium chloride will cause waste, and using too little will not achieve the desired drying effect.

2. Packaging of dried items
When using anhydrous calcium chloride for drying, it is necessary to put the dried items into a sealed container and place anhydrous calcium chloride in the container. This ensures that the anhydrous calcium chloride absorbs only the moisture in the container and is not affected by external humidity. At the same time, it can also protect the dry goods from moisture.

3. Avoid contact with skin and breath
anhydrous calcium chloride has a strong corrosive, when using to avoid direct contact with skin and breath. When operating, it is best to wear gloves and masks to prevent anhydrous calcium chloride from causing damage to the skin and respiratory tract. After use, hands and face should be cleaned in time, and a well-ventilated environment should be maintained.

4. Regularly replace anhydrous calcium chloride
anhydrous calcium chloride will become hydrate after absorbing water and generate heat. Therefore, in the process of use, anhydrous calcium chloride will gradually lose the drying effect. Therefore, it is necessary to regularly check the drying degree of anhydrous calcium chloride and replace it in time according to the needs. If it is found that anhydrous calcium chloride has completely become hydrate, it should be replaced with new anhydrous calcium chloride in time to maintain the drying effect.

5. Properly store anhydrous calcium chloride
Anhydrous calcium chloride is a moisture-absorbing chemical that needs to be stored properly after use. Try to avoid anhydrous calcium chloride contact with air and water vapor, you can put unused anhydrous calcium chloride into a sealed bag and store it in a dry and ventilated place to avoid moisture. At the same time, it is necessary to keep anhydrous calcium chloride away from food, beverages and flammable and explosive materials to ensure safe use.

through the above drying skills and precautions, I believe we have mastered the use of anhydrous calcium chloride for drying tips and precautions. In actual operation, we must strictly follow the requirements to ensure safety and drying effect. I hope this article can help you. I wish you all a dry and happy environment!
