Wear-resistant ceramic ball application and performance characteristics

China pneumatic valves, pneumatic valves used in metal industry, metal pneumatic valve used for hundreds of years of history, although the improvement of structure and material of the metal pneumatic valve, but by the performance of metal material is limited, can not satisfy the more and more high wear and corrosion mainly reflects in the strict requirements such as short service life, greatly influence the serious disclosure of the stability of the system. From the traditional metal materials, design and manufacturing process and radical innovation need pneumatic valves.
industrial pneumatic valve, ceramic material is a bold and useful innovation. Ceramic material deformation is small, than the average bond strength, ceramic material of crystal of ionic radius and ionic electricity price is high, the coordination number, the metal is higher, these properties determine the ceramic material tensile strength, compressive strength; , elastic modulus, hardness is very high. Ceramic itself, however, 'brittle' and difficult processing limited the scope of its application in the past ten years, because of martensite phase transformation toughening technology, nano ceramic composite materials and the concept of science and technology progress and development and has made ceramics 'brittle' has been greatly improved and its toughness and strength has been greatly improved, expanded the application scope.
in recent years, in petroleum, chemical, machinery in areas such as new ceramic material is very active, using the ceramic wear resistance, corrosion resistance and wear resistance of the metal materials of wear parts is the development direction of the high-tech materials in recent years on the important market.
product features:
to end all parts with ceramic material, and the chemical stability of high hardness, Rockwell hardness HRC) Contact, second only to diamond media structure. Therefore, this pneumatic valve has wear-resisting, corrosion resistance, corrosion resistance is very high performance, good insulating and stays, small thermal expansion.
u ball lapping with advanced manufacturing equipment and process, high precision ball roundness, surface quality and the seat, self-lubricating ceramics used for practical preparation of Zr, good sealing performance can be obtained.
u radically changed the metal hard seal ball pneumatic valve leakage, torque, sealing surface corrosion defects.
u, ceramic good abrasion resistance, make the pneumatic valve durability, high reliability. Long service life, it is pneumatic titanium alloy valve and monel - of pneumatic valve Times.
u used in high hardness particle medium, or soft particles, but also has the corrosive medium, pneumatic valve has the incomparable absolute advantage, is the only such pneumatic valves suitable media.
ceramic pneumatic valve of the social and economic benefits:
. Ceramic pneumatic valve structure using high-tech new sealing parts and vulnerable parts of pneumatic valve ceramic material, improve the wearability of pneumatic valve products, anticorrosion and sealing, greatly extend the service life of the pneumatic valve.
。 Ceramic pneumatic valve can be greatly reduced by the use of pneumatic valve repair and replacement quantity, improve equipment operation system security, stability, and cut down the cost of equipment repair.
。 Ceramic the use of pneumatic valve can improve the sealing of industrial piping system, can maximum limit reduce leaking, so as to protect the environment.
。 Manufacture of ceramic raw materials, low cost, with aluminum, carbon, silicon and other factors can produce superior performance of ceramic materials, can save a large amount of metal materials and rare mineral resources.
wear-resisting ceramics pneumatic valve is mainly used in electric power, petroleum, chemical industry, metallurgy, mining, sewage treatment and other industrial areas, especially in the high wear resistance, corrosion resistance, resistance to high temperature, high pressure of face, bad working conditions, such ceramic pneumatic valves also showed its excellent performance. Ceramic pneumatic valve can meet high wear and tear, the use of strong corrosive environment, especially outstanding characteristic is long life, ceramic pneumatic valve performance is much better than the other similar metal pneumatic valves. With and science and technology, from the formula, molding, machining and assembly process, etc, the continuous development of the technical progress of ceramic materials tend to be more mature and complete, ceramic pneumatic valve pneumatic valve industry for its excellent growing recognition performance. Using the successful experience of manufacturing ceramic pneumatic valve can also be applied to a wider range of engineering fields.
pneumatic valve (specially used for solar polysilicon Used for: gas silicon powder)
in the delivery of silicon powder, silicon powder, the ball to be wrapped in leakage and other problems, silicon dioxide as high hardness, a ball the average life expectancy is short of causes of the smell of cooking.
jintai merrill lynch this situation, special ceramic powder conveying pneumatic valve, strong corrosion resistance of structural ceramics using application development research, high corrosion resistance of zirconium alloy material, such new pneumatic valve life times than the original pneumatic valve door, solar polysilicon powder conveying equipment management brings a exciting news!
