The silicone ice cube is a daily life product made from silica gel. It is used in hotels, kitchens and cake shops at west point. According to the classification of silica gel, silica gel can be divided into organic silica gel and inorganic silica gel according to its properties and components.Inorganic silica gel is a kind of highly active adsorbent material, which is usually made by sodium silicate and sulfuric acid reaction and through a series of post-treatment processes such as aging and acid bubbles. Silica gel is a amorphous substance, its chemical molecular form mSiO2. NH2O. Insoluble in water and any solvent, non – toxic, tasteless, stable chemical properties, except strong alkali, hydrofluoric acid and no reaction with any substances.Different types of silica gel have different micropore structures due to their different manufacturing methods. Chemical components and physical structure of the silica gel, determines it has many other features of similar materials difficult to replace, high adsorption performance, good thermal stability, chemical stability, high mechanical strength, such as family used as desiccant, humidity regulator, deodorant, etc.; Industry used as oil and hydrocarbon decolorizer, catalyst carrier, variable pressure adsorbent, etc. Separation and purification agents for fine chemical industry, beer stabilizers, thickening agents for coating, friction agents for toothpaste, polishing agents, etc.
