1. Overall description of the project Microjet homogenization technology has become the most important mass production technology and industrial equipment for material preparation and nanodispersion. It plays an important role in carbon nanomaterials such as graphene materials, carbon nanomaterials, nanocarbons, etc., and has gradually developed specific applications in graphene/carbon nanotube lithium battery conductive fluids, drug targeting reagents, conductive inks and other industries, and has been rapidly promoted as a new technology, replacing traditional valve-type dispersion and preparation equipment. Promote the rapid development of the carbon nanomaterials industry. The ultra-high pressure microjet homogenizer used in this project for preparing nanomaterials and targeted nanomaterials has been upgraded from the previous motor crankshaft structure to a hydraulic workstation, and from an ordinary valve-type structure to a five-level ceramic series reaction chamber. The core components have been authorized to obtain the patent mdash; mdash; emulsification chamber device and method of high-pressure homogeneous emulsification equipment for nanoscale preparation (patent number: ZL2012103033398.7). The operating pressure has also been increased from the previous 1000bar to the existing 3100bar, greatly improving its technical threshold and technical requirements. 2. Advanced nature and innovation The main innovation point is to abandon the design concept of flat valve components of valve homogenizers for hundreds of years, and adopt a fixed component microporous spray chamber to allow the liquid flow to make full use of its own high-pressure microjet cavitation, shearing, and collision effects to achieve the requirements of uniformly dispersing the material and realizing nanoscale. The main advancement lies in first changing the previous multi-component splicing structure, adopting a single firmware, and then using the most advanced laser drilling technology to create a fixed pore of 100 mu;m. Secondly, changing the power structure of the previous power motor crankshaft and adopting advanced hydraulic workstations have always achieved a significant improvement in our main performance indicators and reached the international advanced level. The specific advanced nature and innovative nature also include: 1) the working pressure has been increased from the international maximum pressure of 1500bar in the traditional valve type to our current 3100bar;2) the effect of the micro-jet jet chamber is two or three times better than the dispersion effect of the valve type, greatly improving work efficiency, and many effects cannot be achieved by the valve type at all; 3) Compared with the prior art, the microjet homogenizer has a novel structure. It uses the unique ceramic series reaction chamber structure to cause the two liquid streams of the material to collide at the intersection point, making the material particle size reduced and the mixing more uniform and stable; 4) The high-precision processing of diamond allows it to withstand a working pressure of up to 3100bar, far exceeding the pressure achieved by the prior art. The high pressure greatly reduces the average particle size of the dispersed nanomaterial particles and reduces the peak width. The preparation of nanomaterials has achieved unprecedented results and improved the stability of its products. Test results using this technology show that the ceramic series reaction chamber can well solve its previous technical problems. Using this product, product quality and stability can be well controlled, making it a model for domestic nanomaterial application. 3.
