Explosion-proof electrical explosion-proof joint tool materials which include

Explosion-proof electrical materials are made from beryllium bronze and aluminum bronze. Beryllium bronze alloy and aluminum bronze alloy do not produce sparks when they impact or rub on. They are very suitable for use in the production of explosive, flammable, strong magnetic and corrosive applications. tool.

The BeA-20C alloy was subjected to 561IJ of impact energy in 30% oxygen or 6.5-10% methane air oxygen. No shock and combustion occurred in 20 shots. Because of the good thermal conductivity of copper and the almost carbon-free nature, when the tool and the object are rubbed or bumped, the heat generated in a short time is absorbed and transmitted. Another reason is that the copper itself is relatively soft, and there is a lot of friction and impact. Good concession, not easy to produce tiny metal particles, so we can hardly see sparks, so explosion-proof joint tool is also called non-sparking tools. The main scope of application is: petroleum refining and petrochemical industry, coal mine, oil field, natural gas chemical industry, chemical fiber industry, paint industry, fertilizer industry, various pharmaceutical industries. Oil wheels and liquefied petroleum gas vehicles, aircrafts, warehouses that operate flammable and explosive materials, electrolysis workshops, communications equipment assembly workshops, places that require tools that do not rust, wear resistance, and magnetic resistance.

Ordinary tools and carbon steel pipe bolts in contact with the impact, will produce static electricity, will also produce impact sparks, can not be used in flammable and explosive places. Explosion-proof joint tool and carbon steel will not produce static electricity and sparks, play explosion-proof role .Explosive union tools should be used in flammable and explosive locations. Explosion-proof joint tool is mainly used for large-scale mechanical equipment, machinery manufacturing equipment, large-scale petrochemical equipment, mining equipment, pipeline equipment installation and maintenance, and other pressure vessels are also used.

Explosion-proof joint tool materials include:

1. Bronze, bronze, and bismuth are base steel alloys based on niobium as the basic alloying element, and the niobium content is 1 to 2.5%. At the same time contains trace amounts of cobalt, magnesium, iron and other trace elements.

When the beryllium bronze is subjected to high-speed impact or high-speed friction, its mechanical energy is converted into heat energy when it is applied to the surface of the object, and the surface temperature suddenly rises. However, due to the high conductivity of the material and the heat-conducting string, the heat of the working surface is rapidly transferred to other parts of the workpiece, and the heat of the working surface is drastically reduced. Some particles that break away from the workpiece under impact or friction do not reach the temperature of the ignition source.

The compounds between the beryllium bronze metals are relatively stable and have a high melting point and are not susceptible to severe oxidation. During high-speed impact or friction, the temperature of the surface being acted on or some of the detached particles increases, but they cannot react violently with oxygen and other flammable gases and do not form an ignition source. This material is widely used in the manufacture of important parts and explosion-proof joint tools for certain special occasions.

2, aluminum bronze commonly used aluminum bronze has two kinds: First, when the Al content is less than 9.4% when the metal phase is a dendritic single alpha phase solid solution (Al in Cu solid solution), and second, when the Al content is 1.8-9.4% When, its organization is: α + β1 + a small amount of α + γ2.

Its thermal conductivity is very good, and most of the heat generated when rubbing with other objects is absorbed by the tool and dissipated. The particles that are ground have lower heat and do not cause a mixture of air and flammable substances.

3, J892 copper alloy J892 copper alloy explosion-proof joint tool is suitable for all types of gas applications. In general production, the hardness of J892 copper alloy material after treatment is even higher than that of beryllium bronze material, which is closer to the hardness of steel tool products. At present, the toughness of J892 copper alloy can not reach the level of steel tools, so the use of J892 copper alloy explosion-proof joint tool can not be used in a super-load, but can not be applied to the wrench to extend the arm or hammer in the handle Hit the job. J892 copper alloy explosion-proof joint tool cannot be mixed with corrosive materials such as acid and alkali to prevent corrosion.
