1, beryllium bronze explosion-proof tools
Beryllium bronze is universally recognized as an explosion-proof tool for the manufacture of materials, with beryllium elements as basic alloys, Beryllium bronze in high-speed impact or high-speed friction, its mechanical energy to the surface of the object is converted into heat, surface temperature suddenly increased. However, due to its high conductivity and heat conduction string, the heat of the working surface is quickly transferred to other parts of the workpiece, and the heat of the working surface decreases dramatically. Some particles that are detached from the workpiece under impact or friction can not reach the temperature of the ignition source. Beryllium bronze intermetallic compounds are more stable, and high melting point, not easy to violently oxidized. At high speed impact or friction, the surface of the action or some of the particles removed from the temperature, although there is a rise, but can not be with oxygen and other combustible gases in the intense oxidation reaction, form the ignition source.
Beryllium bronze materials in the magnetic field of the site, with non-magnetic performance, therefore, this material for the production of explosion-proof tools of the best material.
2, aluminum bronze explosion-proof tools Aluminum Bronze is the 1983 Botou Explosion-proof tool factory in Hebei province, Tianjin Explosion-proof tool factory, Tianjin calendering plant cooperation in the development of successful aluminum bronze alloy materials.
1989 Aluminum Bronze Explosion-proof tools by the national explosion-proof product Testing Center qualified, circulation of domestic and foreign markets. Aluminum bronze in high-speed impact or high-speed friction, its mechanical energy to the surface of the object is converted into thermal energy, surface temperature suddenly increased. However, due to its high conductivity and heat conduction string, the heat of the working surface is quickly transferred to other parts of the workpiece, and the heat of the working surface decreases dramatically. Some particles that are detached from the workpiece under impact or friction can not reach the temperature of the ignition source. The compound between aluminum bronze metal is stable, and the melting point is high, and it is not easy to oxidize violently. At high speed impact or friction, the surface of the action or some of the particles removed from the temperature, although there is a rise, but can not be with oxygen and other combustible gases in the intense oxidation reaction, form the ignition source.
Therefore, this material for the production of explosion-proof tools of high-quality materials.
3, J892 explosion-proof tools J892 copper Alloy in 1986 Tianjin Explosion-proof Tool Research institute: Ding Jun Engineers, Wu Yongjing engineers and Botou explosion-proof tool factory (now Hebei in-park explosion-proof Tools Group Co., Ltd.) high-phase engineers and Yangdong River engineer successfully developed, its explosion-proof performance can replace Beryllium bronze explosion-proof tool products, J892 products with explosion-proof magnetic properties, recognized by the Spanish market, applicable to all types of explosive gas use at all levels.
But because the product color resembles the steel tool, the material is particularly expensive, has not been widely accepted by the market. J892 Explosion-proof tool in high-speed impact or high-speed friction, its mechanical energy to the surface of the object is converted into heat, surface temperature suddenly increased. However, due to its high conductivity and heat conduction string, the heat of the working surface is quickly transferred to other parts of the workpiece, and the heat of the working surface decreases dramatically. Some particles that are detached from the workpiece under impact or friction can not reach the temperature of the ignition source. J892 Explosion-proof tool metal compounds are more stable, and high melting point, not easy to severe oxidation. At high speed impact or friction, the surface of the action or some of the particles removed from the temperature, although there is a rise, but can not be with oxygen and other combustible gases in the intense oxidation reaction, form the ignition source. Therefore, this material can be used for the production of explosion-proof magnetic tools.
