Table 1 examples 1 to 5 coil surface temperatures
Table 2 example 1 and comparative examples 1 to 5 coil surface temperatures
As can be seen from Table 1, the coil materials obtained in examples 1 to 5 were exposed to sunlight for 2 hours at 30 to 34℃and the coil surface temperature was in the range of 33 to 48℃and the coil materials were higher in surface temperature due to the use of the same grade of heat-reflective heat-insulating mineral particles in examples 4 to 5, whereas the coil materials were coated with different grades of mineral particles in examples 1 to 3, thereby reducing the coil surface temperature, and therefore the use of different particle size combinations was effective in reducing the coil surface temperature.
As can be seen from Table 2, in comparative examples 1 to 4, respectively, the shale, the black shale, the red color sand and the green color sand are used as the mineral particles on the surface of the coiled material, the surface temperature of the coiled material prepared by the method is up to more than 60 ℃ after the coiled material is irradiated for 2 hours in the environment of 30 to 34 ℃, the quartz sand is used as the mineral particles on the surface of the coiled material in comparative example 5, the surface temperature of the coiled material is up to 42 ℃ after the coiled material is irradiated for 2 hours in the environment of 30 to 34 ℃, and the surface temperature of the coiled material provided by the embodiment 1 of the invention is only 34 ℃ after the coiled material is exposed for 2 hours in the same environment.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
