More than 97% of the heat of the building environment is solar radiation, and about 3% of the heat is the decay of the radioactive elements of the earth's core (infrared radiation) and the surrounding pollution. Solar radiation, as the heat input to the earth's environment by the universe, is on the surface of the earth through light and heat (infrared, ultraviolet). The heat source on the exterior wall of the building is visible light and infrared and ultraviolet rays in the sun and space. The amount of visible light transmitted to the outer surface of the building should not exceed 5%, and the radiant heat of the sun and space infra-red and ultraviolet radiation to the exterior wall of the building is greater than 95%. Cosmic service brand adiabatic reflective insulation (insulation) coatings reflect 85% of visible light, 85% of infrared and ultraviolet heat, and 88% of emissivity. That is to say, in the summer, more than 95% of the radiant heat on the outer surface of the building is reflected back to the atmosphere by the insulating coating, 95%*88%=83.6% of the heat, and less than 5% of the visible part of the heat is also insulated by the coating. Reflected back to the atmosphere, 85% * 5% = 4.25% of heat. In total, the heat on the outer surface of the building is reflected back to the atmosphere by heat insulation paint, which is about 87%. The remaining 13% of the heat on the outer surface of the building can be transferred into the wall through the heat transfer of the paint. However, the adiabatic reflective coating heat insulation (insulation) coating has high thermal resistance hollow core ceramic beads, so the adiabatic reflective heat insulation (insulation) coating has a blocking heat transfer effect on the remaining 13% of the heat of the mesh. About 13% of the total heat that can actually enter the wall through heat conduction does not exceed 5%. Therefore, the adiabatic reflective heat insulation (insulation) coating achieves high temperature on the outer surface of the building and cannot enter the building interior. Thus, it acts as a heat insulation (insulation) (the spacecraft booster discharges high-temperature exhaust gas, which is to protect the booster with thermal insulation coating). In winter, the outdoor temperature is lower than the indoor temperature. The heat in the room is mainly the infrared heat emitted by the human body and the heat generated by the furniture and electrical appliances. When the heat is transferred to the surface of the heat-insulating paint, it is returned to the room by the heat-insulating paint by about 87%, and only about 5% of the heat is transferred to the paint through the paint. Lost in the atmosphere. Therefore, the insulation of the room is achieved (this paint for the submarine is used to keep the cabin warm). In summary, at high temperatures, the adiabatic reflective thermal barrier coating achieves thermal insulation with high reflection and high emission; at low temperatures, the thermal insulation coating achieves thermal insulation with high reflection and high emission. 1. Q & A: Dark adiabatic reflective insulation coatings absorb heat but are negligible. Since the proportion of inorganic pigments (dyes) in the coating is less than one-thousandth of the amount, and the colored coating absorbs only the heat of the visible portion, the main portion of the heat (infrared and ultraviolet rays) is not absorbed. Therefore, the amount of heat absorbed by the colored paint is only about 100,000 per 100,000. 2. In cold regions, it is best to use adiabatic reflective insulation coatings both indoors and outdoors. The insulation performance can be superimposed and the effect will be better.
