At home and abroad, many years have used hot pressing or electroplating technology in the manufacture of diamond tools such as stone sawing heads, petroleum geotechnical drill bits, polishing dressing tools and ceramic tools. The former technology mainly melts the binder phase and fills the carcass material to encapsulate the diamond and shape it to form a product under a certain temperature and pressure; the latter technique is to use a suitable unit under certain process conditions or The multi-metal metal bonds the diamond to the preformed product substrate. The main disadvantage of the two technologies is that the interface strength between the diamond and the substrate is low, leading to early shedding and affecting the service life of the tool bottom.
This project mainly develops active brazing materials suitable for diamond brazing and corresponding brazing technology. It aims to obtain high bonding strength between diamond, brazing material and matrix without affecting the strength of diamond itself. Improve the cutting edge of the diamond, and adjust the matching and post-processing of the different processing objects to solve the matching problem between the tool and the processing object, so as to give full play to the sawing and grinding effect of the diamond. In addition, the granulation technology or the auxiliary process is used to realize the orderly distribution of diamonds, and the production cost is reduced while properly distributing the load and desizing ability.

At present, with the increase of global population and the development of industrialization, more and more solid wastes such as municipal solid waste and industrial solid waste are produced. How to effectively dispose of garbage is a problem that people all over the world are facing. On the basis of our previous experience and continuous research and innovation, our company finally developed MSW Gasification Power Plant. According to different treatment methods, it can be divided into Msw Gasification, Municipal Solid Waste Power Plant and Rdf Power Plant (garbage into derivative particles RDF) and other waste energy projects.
