Description
Silica gel packets for electronic desiccant is an adsorbent with a strong adsorption capacity, completely exposed to the air (relative humidity 90%), at the temperature of 25℃, fully absorbed 30% to 35% of water in 24 hours. Silica gel packets is a kind of material formed by the chemical reaction of sodium sulfate artificially. The numerous networks of capillary Spaces and this structural characteristics of silica gel desiccant make the water locking performance of silica gel desiccant very good.The silica gel packets are DMF & HF free, and non-toxic.
Features
1. Besides moisture proof, it can also effectively prevent mildew, rust, oxidation and other conditions.
2. Fast moisture absorption, effective control of relative humidity. It can protect products from moisture.
3. Silica gel is chemically inert. It will not have any negative effects on the product.
4. Silica gel is odorless and odorless. It poses no threat to health in accordance with the eu RoHS environmental protection directive.
5. Effective and high cost performance. It can be used repeatedly (it can be used again after being dried for 24 hours at 100℃-120℃.)
6. Easy to use, just put in.
7. Shelf life is more than 12 months.
Application of Silica Gel Desiccant
1. Household Goods: clothes, quilts, bags and small leather goods, handbags, leather gloves, hats, etc.
2. Important documents, data, files, filing cabinets.
3. Collection:the calligraphy and painting, stamp and so on.
4. Ideal for protecting the camera, lens, microscopes, telescopes, video tapes and computer diskettes, etc
5. Widely used in precision instruments, leather, shoes, clothing. Prevent mildew.
6. Warehouse, closet, storage which has good sealing performance.
Notes for Use of Silica Gel Desiccant Packets
1. Please don't mix it with the food or put it in the water and near the eyes.
2. Please put it where children can not touch althought the silica gel is non-toxic
3. The function of silica gel desiccant is to absorb moisture,in order to play its role. They must be in the relatively sealed environment. the package airtight as possible, the better the performance of the silica gel desiccant, if tightness is not good enough. Please increase the dosage of silica gel desiccant.
