Abstract

The invention discloses a terahertz material having antibacterial fresh-keeping and deodorizing effects as well as a preparation method and application of the terahertz material. The terahertz material comprises the following raw materials, in parts by weight: 40-65 parts of SiOx, 1-8 parts of Al2O3, 5-15 parts of ocher, 1-2 parts of barium tungstate, 30-45 parts of CaCO3, and 15-35 parts of TiO2. The preparation method comprises the following steps: mixing the raw materials according to the ratio, performing pulverization until the fineness reaches 200-500 mesh, adding an appropriate amount of water, performing stirring, performing conversion by a circular rotating disc to form small spheres, allowing the small spheres to enter an oxygen-free environment, performing heating to 600-1200 DEG C, maintaining the temperature for 3-8 h, performing pulverization, performing powder processing, and performing enhancement treatment by using a terahertz irradiation ray to obtain the terahertz material, wherein the terahertz irradiation ray has the following 5 different frequency bands: 2.3x10<11> Hz, 5.5x10<11> Hz, 1.1x10<12> Hz, 2.3x10<12> Hz and 5.5x10<12> Hz. The material provided by the invention has the antibacterial deodorizing and fresh-keeping effects.

Description

technical field [0001] The invention belongs to the technical field of terahertz, and in particular relates to a terahertz material with antibacterial, fresh-keeping and deodorizing effects, a preparation method and application thereof. Background technique [0002] At present, activated carbon is the most widely used method for deodorization. At the same time, there are also equipment on the market that uses ozone to eliminate odors, CH-CUT formaldehyde catalytic decomposition technology deodorizer, and refrigerator deodorant spray. They respectively have unsatisfactory problems such as incomplete deodorization, cumbersome operation requiring maintenance, consumables, high price, delicate catalytic components, fear of water and dust, etc. [0003] The current physical fresh-keeping methods include drying, low temperature, sealing after sterilization, vacuuming, and inert gas in the sealed package. [0004] The terahertz wave released by the terahertz material with antibact...
