Description

A new type of nanomaterial preparation device

technical field

The invention relates to the technical field of nanomaterial preparation, in particular to a novel nanomaterial preparation device.

Background technique

Nanoscale structural materials are referred to as nanomaterials for short, which refer to the size of their structural units ranging from 1 nanometer to 100 nanometers. Since its size is close to the coherence length of electrons, its properties are greatly changed due to the self-organization brought about by strong coherence. Moreover, its scale is close to the wavelength of light, and it has the special effect of a large surface, so its properties, such as melting point, magnetism, optics, thermal conductivity, electrical conductivity, etc., are often different from the overall state of the substance. the nature of performance. The preparation method of nanomaterials is divided into different methods according to different principles: according to different preparation methods, it is mainly divided into construction method and pulverization method, and according to different reaction states, it is mainly divided into dry method and wet method. According to the preparation method, it can also be divided into chemical method (precipitation method, phase transformation method, aerosol reaction method, etc.), physical method (steam condensation method, electric spark method, ion sputtering method, etc.) and comprehensive method (PECVD, LICVD, etc.) and evaporation condensation method under inert gas (inert gas evaporation and vacuum in-situ pressurization methods have successfully developed a variety of nano-solid materials, including metals and alloys, ceramics, ionic crystals, amorphous and semiconductor nano-solid materials). The key to the preparation of nanomaterials is how to control the particle size, how to obtain a narrow and uniform particle size distribution, and how to ensure the chemical purity of the powder.

At present, the preparation of nanomaterials by pulverization requires tedious steps and a lot of processing equipment. When processing nanomaterials, it is necessary to first crush the bulky materials in the crushing device, and then crush them. The crushed raw materials are put into the grinding device for grinding, and the raw materials need to be screened after crushing and grinding. When processing the raw materials, four steps of crushing, screening, grinding and screening need to be carried out. Multiple raw material transfers require four different equipment for processing, which not only increases equipment investment, but also reduces work efficiency
