In the minds of many people, its silica gel desiccant is relatively familiar, and it is mainly used for preventing moisture, drying, mold, etc., but in fact, silica gel desiccant has many other functions, so what are the functions of silica gel desiccant?
The role of silica gel desiccant
As a kind of air purifier, silica gel desiccant can remove moisture in the air to control the humidity in the air. It can also be used as a dehumidification between two parallel sealed glass plates to maintain the transparency of the glass. Silica gel desiccant is also widely used in shipping. Coarse-pored silica gel desiccant is often used as dehydrating agent, desiccant, catalyst carrier, and can also remove organic acids and water in transformer insulating oil. Moreover, because the pore size of silica gel desiccant is relatively large, it is also a raw material for deep processing of silica gel and can be used for drying and moisture absorption.
Precautions for the use of silica gel desiccant
1. Do not put too much silica gel desiccant to avoid staining the bottom of the crucible.
2. When moving the dryer, hold it with both hands and hold the lid tightly with your thumb.
3. When opening the dryer, you can’t lift the lid up. Instead, you should hold the dryer with your left hand, and carefully push the lid with your right hand. After the cold air enters slowly, push the lid completely. Must be placed on the table.
4. Do not put too hot objects into the dryer.
5. Sometimes when a relatively hot object is put in the dryer, the air will be heated and expanded and the lid will be lifted up, so in order to prevent the lid from being knocked over, you should hold it by hand and push the lid slightly away from time to time .
6. The precipitate after drying can not be placed in the dryer for too long, otherwise it will absorb some moisture and increase the quality.
7. When the color-changing silica gel desiccant is blue, it will turn into pink after being damp. Therefore, the damp silica gel should be dried at 120 degrees until it turns blue and then used repeatedly until it can no longer be used. .
