Wollastonite coated with nano-powder
Wollastonite is an important inorganic fiber mineral that can be used as a reinforcing filler for composite materials and has a wide range of applications. However, due to limitations of its own defects, such as dark color, high density, high hardness, wear processing machinery and other factors, affecting its function, the application is subject to more restrictions. To this end, in January 2004, China's relevant researchers used new technology to coat their surfaces with a layer of nanoparticles to make up for the defects of wollastonite itself. In this way, not only the advantages of wollastonite are maximized, but also the characteristics of coating the nano-powder are added, and the amount of addition in the product is increased. The new technology has surface-modified the wollastonite rather than simply modifying the surface modification of the agent. Its characteristics are: (1) surface nanoparticles modify and passivate the sharp edges formed during pulverization, which reduces the possibility of micro-destruction of plastic products after stress; (2) smoothness along the cleavage plane crystallization The surface is coated with nanoparticles, and the surface roughness of the particles is increased, which increases the compatibility with the polymer matrix, thereby increasing the filling amount and reducing the cost. The application of this technology is of great significance for the further promotion and application of several composite materials.
