Embodiment l

[0013] Example 1: Silicon carbide powder is used, 65% of the material is taken; pure quartz powder, 30% of the material is taken; and 5% of the zirconia powder is mixed.

Embodiment 2

[0014] Embodiment 2: adopt silicon carbide powder, take out 80% of material: pure quartz powder, take out 20% of material and mix.

Embodiment 3

[0015] Embodiment 3: using silicon carbide powder, taking 75% of the material; pure quartz powder, taking 17% of the material; titanium oxide powder, taking 8% of the material and mixing.

[0016] Significant effect of the present invention is described in detail as follows:

[0017] Mix the three raw materials in the above example 1 evenly, coat the infrared quartz lamp tube of the self-made tungsten halogen lamp (the working temperature of the filament is close to 2260-2400K) with ethyl cellulose ethanol and acetone solution, and melt it on the The wall of the lamp tube is coated. When the test temperature is 45°C, the emissivity of the short wave between 2.4 microns and 3.4 microns reaches 0.97. Tests and experiments show that the design of this coating can effectively transfer the visible light and near-infrared radiation of tungsten wires with different voltages. to the mid-infrared region, so that the peak wavelength of the radiation appears at 3 microns from the infrar...

Abstract

The present invention relates to the field of material dewatering technology. The paint consists of silicon carbide powder 65-80 wt%, quartz powder 15-30 wt% and zirconia powder or titania powder 0-8 wt% mixed together. The paint of the present invention may be used to produce characteristic infrared radiation material layer capable of producing infrared irradiation with emitting wavelength 2.4-3.5 micron, which matches for the absorption wavelength of water. The present invention generates the infrared absorption of water molecule to characteristic emitting wave, so as to reduce activating energy of vaporized water molecule and raise the drying effect at low temperature.

Description

technical field [0001] The invention belongs to the technical field of dehydration (drying) of materials, and particularly relates to an infrared radiation coating made with a new chemical formula to obtain the required emitted light wave matching the infrared absorption wave of water molecules, which is applied to agricultural and sideline products and Fabric dehydration drying technology. Background technique [0002] Dehydration (drying) technology is an important process for many agricultural products and industrial products. Currently widely used dehydration (drying) technologies include: thermal drying, far-infrared heating, microwave drying and other methods. Thermal drying is the transfer of heat energy to the material to be dried by the heat transfer medium, which is a macro transfer, high energy consumption, high drying temperature, affecting product quality, and poor civilized production. "Hot" drying and dehydration technology has some insurmountable shortcomin...
