Silica Gel
Silica gel is a vitreous very granular and porous form of silica synthetically from sodium silicate and despite the name is really solid and not a gel.
Silica gel is the most commonly found as accounts packaged in a paper envelope or package. Thus, it is used as a desiccant to control local humidity in order to prevent damage or degradation of some goods. Because doping poisonous and very high moisture absorption, silica gel packets usually bear warnings for the user to not eat the contents. If is consumed, the pure silica gel is unlikely to cause acute or chronic illness, but can be problematic, however. However, some packaged desiccants may poisons include fungicides and pesticides. food-grade desiccant should not include any poisons which cause long term damage to humans if consumed in normal quantities ship with food items.
In many leather goods pepperoni, humidity promotes mold growth and well desiccant Silica gel is used. Condensation can also damage other items such as electronics and can accelerate the breakdown of chemicals like vitamin pills. By adding the silica gel packs, these items can be stored longer. Silica gel can also be used to maintain relative humidity in a high frequency radio wave guide or satellite transmission system as low as possible. Excessive moisture accumulation within of a waveguide can cause arcing within the waveguide itself, damage the power amplifier feeding it. In addition, water droplets that form and condense inside the waveguide, changing the characteristic impedance and frequency, which prevents the signal. It is common for a small compressed air system is used to circulate the air inside the waveguide in a jar of silica gel. Silica gel is also used to dry the air in industrial compressed air systems. The air from the compressor discharge flows through a bed of silica gel beads. Silica gel absorbs moisture from the air, preventing damage to the point use of compressed air due to condensation or moisture. The same system is used to dry compressed air in railroad locomotives, where condensation and ice in air brake lines can lead to brake failure. Silica gel is sometimes used as a conservation tool for controlling the relative humidity exhibitions at the museum and library and storage.
In chemistry, the silicone gel used in chromatography as a stationary phase. In chromatography column stationary phase is most often composed of silica gel particles from 40 to 63 microns. Different sizes of particles are used to achieve separation certain desired molecular sizes. In this application, due to the polarity of silica gel, non-polar components tend to rinse before other more polar hence the name of the normal phase chromatography. However, when hydrophobic groups are attached below, the silica gel first eluting polar components and the method known as reverse phase chromatography. Silica gel is also applied to aluminum, glass, plastic or foil layer chromatography Fine. chelating groups have also been covalently bonded to silica gel. These materials have the ability to remove metal ions selectively from aqueous media. Chelating groups can be covalently bound polyamines have been grafted onto a silica gel surface to produce a material of higher mechanical integrity. The silica gel also combined with alkali metals to form an M-SG reducing agent.
