Silicone desiccant is generally placed in pharmaceuticals, machinery, optics and electronics, precision instruments, meters, seeds, processed foods, tea, various chemical fiber textiles, leather shoes, leather, sports shoes and cultural relics, cameras, arts and crafts, etc. Anti-mold items, so it is widely used. Today we will learn how to check the moisture absorption of silica gel desiccant.
1. Tear off the silica gel desiccant bag, take the silicone raw material and shake hands tightly to see if there is heat, heat dissipation means that the silica gel desiccant is still effective.
2. If blue or orange silica gel desiccant particles are added, if the silica gel granules have changed color, it means that the silica gel desiccant has failed.
3. Fill a small cup of cold water, tear off the silica gel desiccant bag, and pour the raw materials into the water. It will be effective if the silica particles are exploded into pieces and the sound of "嚓嚓" sounds.
4. Take a small bag of silica gel desiccant, weigh it well and mark it. At the same time, put a small cup of boiling water on it. Spread the silica gel desiccant on the mouth of the cup (no water), and then weigh it every 1-2 hours to see if the weight will Increase, it is effective to increase.
The above is the method to test the moisture absorption rate of silica gel desiccant. In addition, silica gel has a strong adsorption capacity and can have a drying effect on human skin. Therefore, you should wear work clothes when handling. If the silicone gets into your eyes accidentally, rinse with plenty of water and consult a doctor as soon as possible.
