The main features of silica Aerogel
Silica aerogel’s unique structure gives it the properties of high heat insulation and low sound transmission. Water glass is a rational choice when making silica jelly. Water glass is an alkali silicate made from silicon dioxide, alkali oxides and water. It is also known by the name sulphuricine. Water glass can be classified into two types by the alkali metallic, which are potassium water glass or soda water glasses. This stage will show you how to prepare silica aerogels using low-cost silicon sources.
Silica aerogel’s main purpose
1. Thermal insulation
Thermal insulation is the most popular use for silica gel. Silica aerogel is thermally conductive at a level below 0.02W/(m*k) and lower than air. Silica aerosol has the highest thermal insulation properties in the current process. It can be used for national defense, industry, and scientific research. It can also serve as a pipeline insulation. , Insulation glass for refrigeration, heat insulation glass for clothing, heat insulation glass for heat.
2. Catalyst and catalyst
Silica gel’s strength and heat transfer can be continually improved through research and development. This can allow silica gel to be used in catalyst carriers and catalysts. Organic fusion of SiO2 & TO2 or cohydrolysis Si and metal alkoxide can produce TO2-SiO2 Aerogel. This will increase silica aerogel’s specific surface area and adsorption efficiency.
3. Acoustic delay
Silica gel is able to transmit sound through its pores due to its unique porous nanostructure. There will be significant energy loss at this point, which decreases the sound wave amplitude and slows down sound speed. Aerogels can also transmit very little in solid materials. This silica aerogel, which is based on the above, has a high rate of speed, large acoustic interference propagation range, and the advantages of corrosion resistance as well as aging resistance and high temperature resistance. Silica aerogel can now be used in ultrasonic instruments, acoustic instruments, soundproof windows.
