How to effectively prevent the aging of silica gel products?
Silica gel products are silica gel products as the main raw material, silica gel is a granular, glass, porous form of silica prepared from the synthesis of sodium silicate. Silicone is hard and laborious; Firmer than ordinary household gel-like gelatin and AGAR. It is a naturally occurring mineral refined and processed into any granular or beaded form. As a desiccant, it has an average pore size of 2.4 nanometers and has a strong affinity for water molecules. For Guangdong silica gel products Factory, how to prevent the aging of silica gel products?
Methods:
1, the silica gel products to prevent in ventilated dry place, avoid direct exposure to sunlight;
2, let the water soak for a while, because silica gel has strong moisture absorption ability;
3, in the surface coating of silica gel products or add light blocking agent, paraffin and other treatment to avoid premature aging of silica gel products;
4, add about 1% of amine or phenolic additives in silica gel products, can effectively prevent the effect of heat, oxygen, light and liquid,
For silica gel products, the raw materials of silica gel products will have a storage period, which is greatly related to the temperature. If the temperature is about 20°C, silica gel products can generally be stored for three years without problems. If stored at 35°C to 40°C, it is likely to stick together in less than a year, so try to use silicone products within the specified period of time.
