Advanced ceramic materials as a new material in twenty-first Century, has been more and more attention by scientists, it is a bold and useful innovation in industrial valves.
Deformation of ceramic materials is very small, much higher than the metal with a combination of strength, general crystal ceramic materials composed of small ionic radius, and ion price high, a large coordination number, these properties determine the tensile strength of ceramic materials, compressive strength, elastic modulus, hardness and so very high. However the ceramics "brittle" and difficult to machine limits its scope of application, in recent years, due to the development and progress of martensitic transformation toughening technology, composite materials and nano ceramic branch technical concept, has made ceramics "brittle" has been greatly improved, its toughness and strength has been greatly improved. Expanding the scope of application.
Wear resistant ceramic valves are mainly used in the industries of electric power, petroleum, chemical, metallurgy, mining, wastewater treatment, especially in the face of high wear, high corrosion, high temperature, high pressure and other adverse conditions, but also demonstrated its superior performance. It can meet the high wear and corrosion of the use of the environment, in particular, the prominent feature is the long service life, the performance price ratio is far superior to other similar metal valve. With the continuous development of science and technology and progress of ceramic materials from the aspects of formulation, molding, machining and assembly process of the technology is more mature and complete, ceramic valves are increasingly recognized by the industry for its excellent performance. The successful experience of making ceramic valves can also be applied to a wider range of engineering fields. |
