Oriented heat-absorbing film material and method for applying the same

Abstract

The invention relates to an oriented heat absorption film material and a spreading method thereof. The oriented heat absorption film material is prepared through a method including the steps of S1, grinding, by weight, 20-55% of crystalline manganese oxide, 5-25% of tantalum carbide, 5-10% of hafnium carbide, 2-20% of fluorphlogopite mica and 5-30% of crystalline iron oxide into a powder materialwith granularity of 100-250 mesh, wherein the total weight percentage of all the components is 100%; S2, heating the powder material obtained through grinding in the step S1 in a resistance furnace at950-1200 DEG C for 6-8 hours to obtain a solid material of the oriented heat absorption and energy conservation film material, and adding pure water accounting for 10-30% of the total weight of the solid material and inorganic high-temperature-resistant liquid gel accounting for 10-20% of the total weight of the solid material to be evenly mixed in a mixer for 7-10 h so as to obtain the orientedheat absorption film material. The film material is high in radiation intensity, generates a radiation magnetic field perpendicular to the tangential direction of the surface of a heated body under the effect of a high-temperature heat source, and enhances the heat energy absorption efficiency of a heated medium and greatly improves the heat energy transmission efficiency when directly acting on the heated medium.

Description

technical field [0001] The invention belongs to the technical field of film layer materials for high-temperature furnaces, and in particular relates to a directional heat-absorbing film material and a coating method thereof for coating on the surface of a heated body of a boiler or a heating furnace. Background technique [0002] Since the reform and opening up, China's economy has developed rapidly, and various construction projects have made great achievements, but they have also paid a huge price in resources and the environment. The contradiction between economic development and resources and environment has become increasingly acute, and the public's response to environmental pollution has become more and more intense. [0003] In the structure of my country's energy consumption, the energy consumption of power station boilers, industrial boilers, heating furnaces, industrial furnaces, and domestic heating boilers accounts for 76% of the total energy consumption, and car...
