FAQ
1. What is the thermal insulation principle of aerogel hydrophobic coating?
The heat conduction of aerogel is mainly determined by solid heat conduction and radiation heat conduction due to its high porosity, uniform distribution of nanoparticle skeleton structure and size pore size. Its no convection effect, infinite shielding plate effect, infinite path effect and so on effectively prevent air convection, reduce heat radiation and heat conduction, so as to achieve good heat insulation effect.
2. Does aerogel hydrophobic coating have environmental advantages?
Aerogel hydrophobic coating is usually environmentally friendly, for example, does not contain harmful substances, does not produce pollution during production and use, and meets the requirements of modern society for environmental protection.
3. How durable is the aerogel hydrophobic coating?
Generally has good durability, can withstand the test of various harsh environments, such as ultraviolet radiation, high temperature, low temperature, acid and alkali corrosion, long-term use is not easy to appear aging, falling off and other problems.
4. What is the market prospect of aerogel hydrophobic coatings?
With the continuous improvement of performance requirements such as waterproof and heat insulation in various industries, the market demand for aerogel hydrophobic coatings is expected to continue to expand and be applied in more fields, bringing more convenience and safety to people's lives and industries.
5. What special areas can aerogel hydrophobic coatings be used in?
For example, it can be used to prepare reversible superhydrophilic - superhydrophobic silica aerogel to achieve reversible control of hydrophilicity and hydrophobicity. It can also be used for atmospheric water collection materials, such as hydrophilic/hydrophobic core-shell aerogel, to generate electricity while collecting atmospheric water.
