The Anding Waste Sanitary Landfill, located in Anding Township, Daxing District, Beijing, handles 700 tons of waste daily, mainly from domestic waste in Xicheng District and Daxing District. After the completion of the second phase of the expansion project this year, the daily garbage disposal capacity will double to 1,400 tons. He Liang, deputy general manager of Beijing Sanitation Group, said that in 2007 Beijing Sanitation Group established Beijing's first environmental technology research and development center, and after three years of independent research and development of landfill gas efficient collection and production of clean fuel technology products. In 2010, Beijing Sanitation Group built China's first landfill gas liquefaction natural gas demonstration project in Anding Landfill, with an annual treatment capacity of 5.6 million cubic meters. According to calculations, this technology can produce 2.394 million cubic meters of liquefied natural gas per year, which is equivalent to 2.3 million liters per year of 93 gasoline, and at the same time achieve CO2 reduction.
52,100 tons/year.
AlNiCo material is comprised of aluminum,nickel,cobalt and iron with varying additions of other elements. There are two different manufacturing processes for AlNiCo:Cast and sintered. Cast AlNiCo can be made into many sizes and shapes,whereas Sintered AlNiCo is usually restricted to smaller sizes. However,both processes lead themselves to complex geometries and configurations. Standard Sintered AlNiCo has tighter dimensional tolerances due to its processing. It also has slighty lower magnetic properties,but better mechanical strength than Cast AlNiCo products. They are most suitable for small sizes that are less than 1 oz. It also results in parts that are structurally stronger than the cast alnico magnets. With the sintering process, one can achieve relatively close tolerances without any grinding.
Production: costing and powder metallurgy
Constitution: Al-Ni-Fe-Co
Performance: well performance in temperature stability
Processing: various sizes and shapes.
Application: Applied in instruments and other like fields..
The name of Alnico magnets comes from its main compositions-Al, Ni, Co. They are made through casting and sintered. They are inexpensive and have wide temperature stability. Thus, compared to other permanent magnet materials, they have such obvious advantages as bellow:
1. solid and breakable
AiNiCo magnets
In the 1930s, early permanent AlNiCo magnets came into being and predominated over the permanent magnetic material due to its excellent properties. Alnico Magnet is a kind of alloy formed by Al, Ni, Co and other trace elements. Its function and magnetic performance vary because of different compositions of metals. There are two kinds of production, costing and sintered. Through costing, magnets can be manufactured into various sizes and shapes. But sintered is suitable for making small size of magnets. The dimensional tolerance of blanks by sintered is better and more workable than that by costing, but the magnetic properties are slightly lower than costing products. Among the magnetic materials, AlNiCo magnets have the lowest reversible temperature coefficient, and its working temperature is up to 600 ℃. AlNiCo magnets are commonly applied in all kinds of instrumentations and other fields.
Advantages:
1. High Frequency Induction Melting Technology. Our raw materials are in accordance with the standards of International Environmental Protection Organization (IEPO) and ROHS
2. A high standard of gold finishing techniques. The minimum tolerance can be ±0.01mm.
3. Thermal control of the directional columnar crystal ingot Technology.
4. Automatic Heating Equipment to make sure consistency of magnet properties.
5. Laboratory of Physics and Chemistry for studying the relation between AlNiCo properties and its constitution and developing new kind of magnets by using new achievements in scientific research.
