This kind of wireless mouse made of cork does not need to install a battery. Your hand will generate electricity during the movement of the mouse. Because there is a piezoelectric element in its left and right click buttons, the scroll wheel will generate kinetic energy when moving the mouse, and the kinetic energy will be converted into electrical energy through the internal structure of the mouse to maintain the normal operation of the mouse.
Semi-friable aluminum oxide is a kind of high-grade corundum synthesized by some advantages of brown corundum and white corundum. Its friability is between white corundum and brown corundum. Its grinding performance is unique, and its application range is wide. Semi-friable aluminum oxide has good toughness and self-sharpening. It can be used in the manufacture of ceramic grinding tools, resin grinding tools and coated abrasives. The bonded abrasive tools with semi-friable aluminum oxide have high durability, good self sharpening and retention. Under the same conditions, the surface quality, the processing efficiency and the durability of the grinding tools which produced from semi-friable corundum are better than those of brown, white, chromium and single crystal corundum when processing some workpieces. For rough grinding, the machining efficiency can be improved, and the surface quality of the workpiece can be improved by fine grinding.
