Aerogel powder, with a density of 0.08g/ml, has excellent thermal insulation properties (0.015 +/- 0.002w/mk), wide thermal insulation range (-100C - 1000C), water resistance, weather resistance, light weight Quality (weight reduction), fire resistance, corrosion resistance, sound barrier properties. As a new type of filler or additive, aerogel micropowder is widely used in the following fields: industrial thermal insulation coatings, building thermal insulation coatings, building thermal insulation materials, fireproof materials, industrial waterproof and anti-corrosion paints, thermal insulation, fireproof fabrics.
SiO2 aerogel is the easiest to prepare and the most widely used category. It takes air as the main component, and amorphous SiO2 as the basic skeleton. , thermal, electrical, optical, acoustic and other aspects show unique properties, such as its thermal conductivity at room temperature can be as low as 0.013w/(mk). At the same time, it also includes the properties of low thermal conductivity, low density, high porosity, high light transmittance, high specific surface area, low refractive index and low sound velocity, so it has broad application prospects in many fields.
Main Advantage
1. The special structure of aerogel and its waterproof and compressive properties allow it to last for more than 20 years, much higher than traditional materials.
2. The thermal insulation performance is 3 to 5 times that of traditional materials. It has excellent thermal insulation performance and low heat loss after thermal insulation. According to actual engineering calculations, it can save energy by more than 20%.
3. Under the same surface temperature, the extremely low thermal insulation thickness makes the diameter of the outer protective pipe significantly reduced, saving a lot of steel pipe costs.
4. The unique nano three-dimensional network structure provides extraordinary high temperature stability, avoiding the phenomenon of deformation accumulation and sharp decline in thermal insulation performance caused by vibration.
5. With excellent overall waterproof performance, water repellency rate 99% min, isolating liquid water, while allowing water vapor to pass through, it will not be affected by moisture, water absorption and corrosion of pipes, it is the choice of thermal pipeline insulation material.
6. Aerogel insulation felt has good flexibility, tensile and compressive strength, can resist brutal construction, and will not settle or deform after long-term use.
7. Does not contain substances harmful to the human body, green and environmentally friendly.
