Reuse method:
This product is orange before moisture absorption, and becomes dark green after moisture absorption and saturation. After complete discoloration, it needs to be replaced with a new product or recycled. It can be reused by the following methods
Method 1: In sunny and dry weather, place it in the sun for about 3 hours to evaporate the moisture absorbed by the desiccant package and restore its performance (this method may cause incomplete color recovery and poor water absorption. weak)
Method 2: Put it in a heatable dish and heat it in a microwave oven. The temperature is controlled between 80-100 degrees Celsius, or you can choose a medium-low fire to heat it. Because the microwave oven brand is different, the heating power is different, so the heating time is also different. It is not the same. It is recommended that you take it out and observe it every 5 minutes after heating until it returns to orange color (after heating, the temperature is high and it is hot).
