preparation example Construction

[0015] The preparation method of the spectroscopic functional ceramic powder that can accelerate heat exchange provided by the present invention comprises the following steps:

[0016] (1) The following various components in terms of mass percentage: 5-10% of chlorite, 30-40% of kaolin, 5-10% of cordierite, 30-35% of tourmaline, 1-5% of iron dioxide %, vanadium pentoxide 1-2%, copper oxide 3-7%, polyvinyl alcohol binder 5-10%, carry out crushing and milling, and carry out thermal mixing, the temperature of the thermal mixing is 30°C;

[0017] (2) Roll the uniformly mixed raw materials in step (1) into spheres by spraying and adding powder, and then fire them. Naturally lowered to room temperature;

[0018] (3) Pulverize the raw material sphere fired in step (2) to make a powder with a diameter of 5 microns.

Embodiment 1

[0020] The various components and mass percentages of a spectral functional ceramic powder are as follows: 5% chlorite, 30% kaolin, 10% cordierite, 31% tourmaline, 5% iron dioxide, pentoxide Vanadium 2%, copper oxide 7%, polyvinyl alcohol binder 10%.

Abstract

The invention relates to a spectrum functional ceramic powder capable of accelerating the heat exchange of an appliance shell and a preparation method thereof.The ceramic powder comprises components in percentage by mass as follows: 5-10% of hard chlorite, 30-40% of kaolin, 5-10% of cordierite, 30-35% of tourmaline, 1-5% of iron dioxide, 1-2% of vanadium pentoxide, 3-7% of copper oxide and 5-10% of polyvinyl alcohol binder, wherein the invented spectrum functional ceramic powder can be coated onto the surfaces of the appliance shells needing cooling, heat radiation and heating; the spectrum functional ceramic powder having above 90% of infrared reflectivity is capable of increasing heat radiation ratio in heat conduction, improving heat exchange rate of heat radiation, cooling and heatingtools as well as decreasing required amount of radiator fins and reducing electricity consumption and fuel amount.

Description

technical field [0001] The invention relates to a composition component capable of accelerating heat exchange and a preparation method thereof, in particular to a spectroscopic functional ceramic powder capable of accelerating heat exchange of an appliance shell and a preparation method thereof. Background technique [0002] At present, power transmission and transformation appliances, voltage regulators, air-cooled and water-cooled air compressors, cooling fins of air-cooled internal combustion engines, radiators for various internal combustion engine water tanks, refrigerators, refrigerators, air-conditioning evaporators, heat exchangers, etc. According to the working conditions, the surface area of ​​the metal fins is increased, and the temperature is cooled by air cooling, water cooling and forced air exhaust. This type of cooling and heat dissipation not only consumes power and energy, but also consumes a lot of metal materials, and at the same time leads to a huge size...
