Detailed description and definition of silicone products


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 diameter 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.
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. 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. The silicic acid gel is allowed to stand for several hours to be aged, and then the soluble salts are washed away with hot water, dried at 60-70°C and activated at about 300°C to obtain silica gel. The silicic acid gel is soaked in a solution of cobalt chloride and then dried and activated to obtain a color-changing silica gel.
Food grade silica gel is non-toxic and tasteless, insoluble in water and any solvent. It is a highly active green product. Food grade silicone has inherent thermal stability (-40°C-230°C). Suitable for different occasions. The product has a good flexibility to meet different needs.
