Mesoporous insulation material energy-saving technology
Technical research background
Thermal insulation materials play a huge role in energy conservation and consumption reduction in thermal power, petrochemicals, cement, steel, kilns, construction and other fields. Using thermal insulation materials with better energy-saving effects to insulate pipelines, equipment, etc. can effectively reduce energy consumption.
At present, thermal insulation materials are mainly divided into traditional thermal insulation materials and nanopore thermal insulation materials:
- Organic thermal insulation materials:The thermal conductivity is low, but it is flammable, has low strength, is easy to age, has a short service life, and needs to be replaced frequently.
- Inorganic thermal insulation materials:The thermal conductivity is relatively high, and the thickness needs to be increased to improve the thermal insulation effect. It takes up a lot of space and has a high water absorption rate.
- Disordered nanopore insulation materials:The thermal conductivity is low, which saves energy. The thermal conductivity (200~500℃) is less than half of traditional materials under the same working conditions, and it is not flammable, but it is expensive.
- Ordered mesoporous insulation materials:As an upgraded product of disordered nanopore thermal insulation materials, it has an ordered nanopore structure, lower thermal conductivity, and greatly improved high temperature resistance. The long-term use temperature can reach 650°C and 1200°C respectively.
