Problems solved by technology

[0002] At present, thermal insulation coatings are widely used in various fields of the national economy. However, general thermal insulation coatings are poor in reducing convection and radiation heat transfer, and the thermal insulation layer is thick, not resistant to vibration, high water absorption, and long service life. Short, poor anti-corrosion ability
