Are there nano-ceramics?
2022-08-18
Nano-ceramics, in essence, refer to ceramics that have nano-effects due to their small grain size to the nanometer level. There are currently no three-dimensional nano-ceramics on the market. Therefore, the ceramic balls and ceramic bearings we see with the naked eye do not have the so-called nanometer.
The wear-resistant particle adhesive is based on modified resin and special curing agent, and uses hard particles such as alumina, silicon carbide, and brown corundum as the aggregate. Different particles and particle size gradations are selected according to different working conditions. A compound of various modifiers. It is used for the repair and protection of particles, dust and slurry erosion and wear in coal washing, mineral processing, metallurgy, building materials, cement, power and other industries. There are many kinds of wear-resistant granular adhesives, and different working conditions require Xu to choose different materials.
The wear-resistant particle adhesive is distinguished according to the diameter of the nano-ceramic particles, and can be divided into two types: RJ-YHL-1.0-2.0 small particle wear-resistant particle adhesive and RJ-YHL-2.0-3.0 large particle wear-resistant particle adhesive.
RJ-YHL-1.0-2.0 contains a high concentration of nano-ceramic small particles as an epoxy repair agent for wear-resistant hard points, which is suitable for resisting particle wear with a diameter of less than 3mm.
Summary: It is difficult to complete the connection between the wear-resistant ceramics and the metal parts of the equipment by traditional connection methods such as welding. The high-temperature resistant ceramic particle glue is used for bonding to complete the connection between the wear-resistant ceramics and the metal parts of the equipment. This skill has been promoted to electric power, metallurgy, mining, cement and other industries through development and has been widely used and recognized. The use of wear-resistant ceramic particle glue can firmly bond the high-purity wear-resistant ceramic sheet to the surface of the equipment that has been severely eroded by the material, prolong the service life of these equipment, strengthen the protection of such equipment, and then reduce the replacement of new equipment, effectively reducing maintenance costs, etc.

How fast can ceramic bearings withstand?
First of all, it depends on whether it is an all-ceramic bearing or a ceramic ball bearing (hybrid bearing). If it is an all-ceramic bearing, the speed is usually lower than that of a steel bearing. If it is a ceramic ball bearing, it can theoretically achieve a higher speed than a steel bearing. However, the specific speed needs to be analyzed according to the specific model/accuracy/configuration.
