Silica gel applications properties production types
Silica gel on
Silica gel has unique properties and is widely used. There are methods for making it, and there are different types.
Its properties are also porous, with strong adsorption force. It can hold water vapor and keep it dry; it can attach impurities, and the pure liquid is pure. And it has good thermal stability, temperature resistance without changing its quality, and can be settled between high and low temperatures. Chemical stability is stable, and it does not respond to all common things, so it is quite convenient to use.
As for applications, in the field of storage, silica gel is placed to dehumidify, protect grain storage, and prevent mildew rot. In electronic equipment, accompanied by the side of the component, moisture-proof gas intrusion, to ensure its operation. In the place of medicine, it is also used to dry medicines to prevent their deterioration and ensure the constant efficacy of medicines. In the process of chromatographic separation, silica gel is used as a column material. Due to its difference in adsorption, it is divided into the mixing of various substances and the analysis of its pure quality. It is essential for scientific research and pharmaceuticals.
The method of its production is mostly responded by water glass and acid. For water glass, the solution of sodium silicate also reacts chemically with acid agents such as sulfuric acid to produce a silicic acid gel. After aging, washing with water, drying, and activation, the finished silica gel is obtained. When aging, the gel structure is gradually stabilized; washing with water removes impurities to purify its texture; drying and removing water to determine its shape; activation and energy enhancement to strengthen its adsorption.
Silica gel and the like are also diverse. There are fine-porous silica gel, with tiny pore size and strong adsorption force, which is suitable for drying and precision materials; coarse-porous silica gel, with large pore size and fast liquid absorption, is mostly used to absorb a large amount of liquids or gases. Color-changing silica gel, adding a colorant to it, varies in color with the change of moisture absorption, making it easy to observe its degree of moisture absorption and know its effectiveness.
In short, although silica gel is a small matter, it has great contributions to all industries. Because of its uniqueness, it is made into various categories and should be used in all parties. It is a model of good use of material properties.
