Aerogel insulation felt is a new type of insulation material. Aerogel insulation felt product is a kind of flexible insulation felt made by combining nano silica aerogel with inorganic fiber material through special process. Aerogel solves four major problems of thermal pipe insulation: good insulation effect, steam pipe, fire prevention, and anti-market. At the same time environmental protection is harmless to the human body. The aerogel product is a silica aerogel insulation felt used at temperatures ranging from (-200 ° C to 1000 ° C).
The main defects of the traditional insulation materials in the structure:
1. Because the thermal conductivity of the thermal insulation material is high, the thickness of the thermal insulation layer is required to ensure the thermal insulation effect. The thickness of the insulation layer is large and the amount of civil engineering is large.
2. The traditional thermal insulation material has poor high temperature stability and natural pulverization. After 2-3 years of use, the performance is degraded and damaged, resulting in a large amount of energy waste.
3. The traditional thermal insulation material has the advantages of compression resistance, poor tensile performance, compression, vibration and deformation. The steam pipeline is disintegrated due to moisture and sedimentation, and the heat loss is seriously exceeded.
4. The traditional insulation material has poor waterproof performance, and the relationship between water absorption and moisture after moisture is a certain safety hazard.
5. Poor heat preservation results in large heat loss. Rock wool, aluminum silicate fiber is harmful to the human body.
Use aerogel insulation blankets on steam pipes
1. The aerogel insulation material has a low thermal conductivity of 0.018 W/(m.k) at normal temperature. The thickness is 1/3 to 1/5 of the conventional material at the same temperature, and the waterproof is convenient.
2. The thermal insulation performance is 3-5 times that of traditional materials, and the heat loss of heat preservation is small. Its special structure is waterproof and compressive, and its thermal insulation performance at high temperature is up to 20 years.
3. The unique nano-three-dimensional network structure provides superior high-temperature stability, avoids vibration and causes deformation and thermal insulation performance to drop sharply.
4. It has excellent overall waterproof performance, water repellency rate ≥99%, isolated liquid water, allowing water vapor to pass through, no moisture, water corrosion corrosion pipeline, is the best choice for construction materials.
5. It has flexible compressive strength, can resist barbaric construction, and does not settle deformation after long-term use, and does not contain substances harmful to human body. Aerogel insulation materials have been used in prefabricated steam pipe production companies, as well as in thermal design institutes.
