Abstract

The invention belongs to the technical field of microwave heat conversion, and specifically relates to a microwave heat conversion material, a carrier and a preparation method thereof. The microwave heat conversion material is made of materials with the following weight ratio: graphite powder 55-65%, ferrite powder 10‑15%, glass fiber 15‑25% and binder 5‑10%. The structure of the present invention is convenient and simple to form, light in weight, has good insulation, acid and alkali resistance, pressure resistance and peeling properties, stable physical and chemical properties, high temperature and heat resistance, strong heat insulation, and high temperature resistance up to 1350 degrees Celsius Compared with the existing heat conversion materials, the wave-absorbing heat energy conversion can increase the heat energy conversion efficiency by 30%, and can be used in microwave waste gas combustion equipment efficiently and at high speed. Compared with the previous RTO burner, the energy saving can reach more than 50% and will not produce Consumables, the preparation process is simple, easy to operate, easy to shape, and low cost.

Description

technical field [0001] The invention belongs to the technical field of microwave heat conversion, and in particular relates to a microwave heat conversion material, a carrier and a preparation method thereof. Background technique [0002] Microwave absorbing material, also known as radar absorbing material or radar stealth material, is a material that can absorb microwave and electromagnetic energy with less reflection and scattering. The basic principle of microwave absorption is to convert microwave energy into energy of other forms of motion through a certain physical mechanism, and convert it into heat energy through the dissipation of the motion. Microwave absorbing materials should have good microwave absorbing properties, that is, microwave absorptivity higher than the required threshold and a wide absorption frequency band. In addition, the microwave absorbing material should also have a small thickness and areal density. [0003] Microwave absorbing materials are ...
