What is a silicone product and how long is the shelf life?


Processed works with silicone as the main raw material are called silicone products. Silica gel is a porous material of different particle sizes that is suitably dehydrated from silicic acid gels. With an open porous structure, it can adsorb many substances and is a good desiccant, adsorbent and catalyst carrier.
Silica gel is a granular, glassy, ​​porous form of silica prepared from sodium silicate. Silicone is tough and hard; more solid than ordinary household gel-like gelatin and agar. It is a naturally occurring mineral refined and processed into any granular or bead form. As a desiccant, it has an average pore size of 2.4 nm and has a strong affinity for water molecules.
Silicon gel is a small (usually bead 2 x 3 cm) file package most commonly encountered in daily life. In this form, it is used as a desiccant to control local humidity to avoid damage to some cargo or degradation. Since silica gel can add chemical indicators and absorb water very well, silicone packs usually assume the content of the user not to warn.
How long the shelf life of silicone products depends on the design used, the properties of the materials, the formulation, and the use environment. Different products have different shelf lives. If the product is placed for several years, its performance will slowly decline, and its various properties Will decline, some of the shelf life of silica gel products are in accordance with the number of uses in accordance with the use of the environment and time, and the main silica gel products shelf life is in accordance with the provisions of manufacturers, different performance products have different shelf life, we are in accordance with the use of the product and performance to provide In general, the shelf life of a product is about two years.
Adsorption of silica gel is mainly physical adsorption, which can be regenerated and used repeatedly. In the alkali metal silicate (such as sodium silicate) solution by adding acid, acidification, and then add a certain amount of electrolyte for stirring, that is, to generate silicic acid gel; or in the more concentrated sodium silicate solution add acid or Ammonium salts also produce silicate gels.
