The thickness of polyurethane thermal insulation material is reduced by about two thirds compared with other thermal insulation materials. Therefore, that space above the floor and ceil can be saved, and the indoor height can be improve.
The outer protective layer can be made of glass fiber reinforced plastic shock-proof shell or black-yellow polyester yellow sheath to enhance the compressive strength and corrosion resistance of the insulating layer. Mainly used for all kinds of pipeline cold storage, storage tanks, pipelines, insulation, partition boards and roofs in buildings.
Extended data:
Common application types and design selection of building thermal insulation materials shall comply with GB/T 17369- 1998 "Application Types and Basic Requirements of Building Thermal Insulation Materials".
In addition to the thermal conductivity of the material, the water absorption, combustion performance and strength of the material should also be considered when selecting. See the corresponding classification guide for the performance characteristics of different thermal insulation materials.
Inorganic thermal insulation materials generally refer to materials with thermal conductivity less than or equal to 0.2.
Using good thermal insulation technology and materials in construction and industry can often get twice the result with half the effort.
Statistics show that every ton of mineral wool insulation products used in construction can save one ton of oil a year. The application of energy-saving residential quarters in Beijing shows that the annual coal saving rate per unit area is 1 1.95438+0 kg standard coal/square meter.
Using good insulation measures and materials to insulate industrial equipment and pipelines can significantly reduce production energy consumption and cost, improve the environment and have good economic benefits.
For example, in industrial equipment and pipeline engineering, good thermal insulation conditions can reduce the heat loss by about 95%, and the investment usually used for thermal insulation materials can be recovered by saving energy for about one year.
