subject: The Use Of Nickel [print this page] Nickel is a traditional raw material, widely used in the field of modern technology and industrial. Most nickel is used in the metallurgical sector, the production of stainless steel and various alloys. Since 1889,the first time discovered the excellent performance of nickel-iron alloy containing more than 3000 kinds of nickel alloys, nickel applications involving more than 30 million items, mainly used for the following purposes:
Nickel can produce a variety of sensors. Manganese constantan (58Cu41NiMn) and constantan (60Cu40Ni) can be made to the resistance of the strain gauge; NiO, or Ni can be used as the reducing atmosphere of the sensor and disc memory; Ni (OH) x as a photoelectric display material; NI easy emission current, widely used for the cathode of the tube, etc. The NI also widely used in high energy rechargeable batteries, such as Ni-Cd, and Zn-Ni, Fe-Ni, Ni-H2 cells, etc..
Compared with other metal powder, nickel is cheaper and not easily poisoned, so it often as an activator for organic hydrogenation, hydrogenolysis, isomerization, HC reforming, desulfurization and gas-phase oxidation catalysis process. The platinum group metals can not be replaced by nickel in the reforming process.
Ti-Ni shape memory alloy in the heating and cooling cycles, with a prototype of the characteristics of the two-way repeated memory heat erosion resistance is strong, it is widely used. The thrombosis filter, used in the medical field as a spinal orthopedic rods, dental orthopedic lip bowstring the cerebral artery folder, plates, artificial joints, femoral head cap, an artificial heart artificial muscles, artificial kidney micropumps. Hydraulic control in the industry for the Jets, tubing connectors, subsea oilfield tubing connector, cable connector. The air heater switch in the home appliance industry, do microwave heater cycle vibration mechanism, the current overheating sensor, dryers, electric ovens and medical instruments and other equipment.
Nickel can be used in a number of new functional materials, such as: hydrogen storage alloy and shape memory alloy. Pure nickel can be processed into plates, tubes, wire, foil, for all aspects of the chemical, textile, food, radar, television, the nickel tube concentrated caustic soda manufacturing equipment, nickel short fiber heat pipe aspiration Rui can be used for the filtration of chemical equipment element, nickel plate for the ultrasonic device, nickel foil for electronic wire connection.
Nickel powder for powder metallurgy products, magnetic alloys, control expansion alloys, welding powder, metal and ceramics. 70% nickel powder is used for the manufacture of batteries, the nickel powder of manufacturing a fuel cell electrode, nickel not only for the usual plating, nickel-coated powder Hop powder, can also be used as a high-temperature spraying material, Raney nickel is commonly used in catalytic hydrogenation of the catalyst ultrafine nickel powder has better catalytic activity.
There are extensive use of metallic nickel powder, mainly used in four areas: (1) carbide (cutting tools, geological mining tools, wear parts, drawing dies, stamping dies, measuring tools, fixtures, shock rock drilling tools, coal mining tools geological drilling tools, oil well drill, etc.); density alloy (aerospace and aviation industry as a the gyro rotor inertia rotating element; military industry as armor piercing, kinetic energy projectiles and missile warheads; health department as electromagnetic shielding materials ; electrical industry as a welding process materials, electrode materials and contact materials; machinery industry as a die-casting mold material); (3) iron-based powder (widely used in automobiles, motorcycles, agricultural machinery, power tools, office machinery, appliances hydraulic parts, textile machinery production); sintered stainless steel powder; making catalyst, the alkaline nickel cadmium batteries, iron-nickel batteries, ceramics, glass, etc.
