What is aerogel?
Many contemporary people will be very puzzled with aerogel, and will ask what is aerogel. This puzzle is equivalent to hundreds of years ago to ask what is plastic. A new type of material has not been widely used in large-scale, not familiar with it. It is nothing more than a new type of material, and plastic, steel, like a similar material.
In short, aerogel is the world's lightest solid material, the lowest thermal conductivity of the material. Of course, this product is still in the research stage, other excellent features remain to be developed, at present, its thermal conductivity is low thermal characteristics have been widely recognized and applied. Adiabatic function of the excellent results, added to the substrate used in the insulation has played a small role.
Next, we explain in detail what is aerogel. First, we analyze what is the gel? Sol or solution in the colloidal particles or macromolecules connected to each other under certain conditions, the formation of space network structure, the structure of the gap filled with liquid as a dispersion medium, such a special dispersion The system is called gel. The gel does not have fluidity, and the interior often contains a lot of liquid. Such as blood gel, agar water content can reach more than 99%. The process of forming a gel from a solution or sol is called gelation.
When the gel takes off most of the solvent, the liquid content of the gel is much less than the solid content, or the space in the gel network is filled with gas, the solid is in the form of a solid, The material is called aerogels and is a nanoporous solid material with network structure composed of colloidal particles or polymer molecules. The solid phase and pore structure are in the order of nanometer.
Aerogel classification is classified into SiO2 aerogels (glass fiber and ceramic fibers) and carbon aerogel (organic aerogel) according to colloidal material.
The aerogel is made into the world's best insulating material by combining with inorganic fibers. This is what we often mention to the aerogel insulation felt, in the long production of two kinds of aerogel insulation felt, a kind of SiO2 aerogel glass fiber insulation felt, a kind of SiO2 aerogel ceramic fiber insulation felt.
The production process of aerogel insulation felt is basically silica sol + catalyst + dopant into the dry fiber blanket, freeze treatment, and then dried and dried, and finally packaged into a tube for easy transport.
Aerogel has many advantages:
1, the longest life, no more than 20 years without replacement.
2, the lowest thermal conductivity
3, thin and light
4, waterproof and moisture-proof, easy storage
5, the highest fire performance, security level A1
6, strong pressure, can withstand brutal construction
7, green, non-toxic and non-corrosive
Our company, Zhengzhou Joda Technology Co., Ltd. Has many diversification and customization in the production of aerogel , not only to meet the functional requirements of the industry, but also in the production process has a superior experience to meet the diverse needs of different. Aerogel as a new era of high-tech materials, will bring a new material application revolution in the future.
