The main features of silica aerogel
Silica aerogel’s unique structure gives it the properties of high heat insulation, sound transmission rate, and large area. Water glass is a rational choice when making silica jelly. Water glass can be described as an alkali-metal silicate, which is made from silicon dioxide or alkali oxides. Two types of water glass are possible by using alkali metallic, which is potassium water and soda water. This stage is the most important for silica Aerogels preparation.
Silica aerogel’s main purpose
1. Insulation with thermal insulation
Silica gel’s most popular application is as thermal insulation. Silica aerogel can have a thermal conductivity less than 0.02W/m*k, or even lower than the thermal conductivity of air. In the present application, Silica aerosol has the highest thermal insulation properties. You can use it in industry, national defense and research. You can use it in pipe insulation. The glass can also be used to insulate pipes, radiator heat insulation and clothing warmth.
2. The catalyst carrier and catalyst
Silica gel’s strength and heat transfer can always be improved. This can allow silica to be utilized in catalyst carriers or catalysts. Organic fusions of SiO2 & TO2 can produce TO2-SiO2 Aerogel. You can increase the specific surface area and adsorption efficiency of silica aerogel.
3. Acoustic delay
The unique nanostructure of silica gel allows it to transmit sound within the pores. There will be significant energy loss at this point, which lowers both the frequency and the amplitude. Additionally, aerogels are very sensitive to solid material transmission. This silica aerogel, which is based upon this, has a high speed and large range of acoustic impedance propagation. It also offers the benefits of corrosion resistance, age resistance, as well as resistance to heat. Silica aerogel is now ready to use in soundproof windows, ultrasonic instruments and acoustic instruments.
