what is magnetic separation process?

Wear is one of the three major objects of tribology research (friction, wear and lubrication) and one of the three main forms of mechanical part failure (wear, corrosion and fracture). From the perspective of the action process, wear and friction generally occur simultaneously and interact with each other. However, the wear mainly focuses on the loss of the surface material, while the friction focuses on the force that hinders the relative motion from the consumption of mechanical energy. According to statistics, 30% to 40% of the world's energy consumption is lost in friction and wear, so most of the work on surface engineering is to overcome the excessive wear of the workpiece. In order to reduce material damage caused by wear, on the one hand, it is necessary to reduce or control the conditions causing wear, and on the other hand, to improve the wear resistance of the material itself. An effective method to improve the wear resistance of the material is to apply a hundred shield coating wear-resistant granules on the worn surface to prepare a wear-resistant protective coating. Epoxy resin is the most widely used matrix resin in polymer composites. It is a thermosetting resin with excellent adhesion and dispersibility to various substrates. It has good leveling and wetting properties. The coating has high mechanical strength, wear resistance, superior corrosion resistance and water resistance. However, after curing, the epoxy resin has high crosslink density, large internal stress, poor deformability of the product, and tends to be brittle. The toughness, fatigue resistance, impact resistance and moisture resistance are poor, which greatly limits its high-tech field. Application in . How can we further improve the wear resistance of the coating?

There are three methods:

One is to modify the epoxy resin matrix;

Second, rigid inorganic particles or nanoparticles can be added to the matrix;

The third is to add wear-resistant filler to the modified epoxy resin.
