Magnesium main uses: applications are mainly concentrated in the production of magnesium alloys, steelmaking desulfurization, also used in rare earth alloys, metal reduction, corrosion protection and other fields. Many steel mills use magnesium desulfurization, the use of magnesium particles of desulfurization effect is better than calcium carbide.
The use of magnesium sacrificial anode for cathodic protection is an effective method of preventing metal corrosion, magnesium sacrificial anode is widely used in petroleum pipelines, natural gas, gas pipelines and tanks, smelters, gas stations, corrosion protection, as well as water heaters, heat exchangers, evaporators, boilers and other equipment.
Magnesium alloy is also widely used in other small areas of our life, such as motorcycles and bicycles, bicycles are new applications of magnesium alloy, mainly used as bicycle frames. The advantage of magnesium alloy is not only lightweight, fast, comfortable, and have a mouth can make the diameter of the tube smaller, thinner tube wall, the frame more strong and solid.
Magnesium alloy folding bicycle frame quality of only 1.4kg; rehabilitation facilities, one of the representative instruments is a wheelchair, commercially available wheelchairs can be divided into standard and lightweight (aluminum alloy or titanium alloy) three kinds according to the quality of the materials used were steel, aluminum and titanium tubes.
Wheelchair frame made of AZ31 magnesium alloy or in addition to the wheels of the rest of the components are basically made of magnesium alloy, the wheelchair can be reduced by about 15% of the weight, both lightweight and flexible. Magnesium alloy in the shipbuilding industry and marine engineering is mainly used for marine instruments, underwater weapons, seawater batteries, diving suits, sacrificial anodes, timing devices. The application areas are countless and play an important role in our lives.
Expanded Information:
But and halogenated hydrocarbons in the anhydrous conditions but the reaction is more violent (generating Grignard reagent) magnesium and carbon dioxide combustion reaction, so magnesium combustion can not be extinguished with carbon dioxide fire extinguishers. Magnesium because it can react with N? and O?, so when magnesium burns in air, it burns violently emitting a brilliant white light, exothermic, producing a white solid.
The change in vinegar is rapid bubbling that floats to the surface of the vinegar liquid and gradually disappears. Some fireworks and flares contain magnesium powder, is the use of magnesium in the air combustion can emit dazzling white light nature. The element magnesium usually has a valence of +2 in chemical reactions.
Transportation precautions: transportation vehicles should be equipped with the appropriate variety and number of fire-fighting equipment and leakage emergency treatment equipment. The exhaust pipe of the vehicle transporting the product shall have a fire stopping device. During transportation, it should be ensured that the container does not leak, collapse, fall or get damaged.
Strictly prohibited and oxidizing agents, acids, halogens, chlorinated hydrocarbons, edible chemicals, and other mixed loads and transportation. During transportation, it should be protected from exposure to sunlight, rain and high temperature. It should be kept away from fire and heat source when stopping over. Transportation vehicles and boats must be dry and have good rainproof facilities. Vehicles should be thoroughly cleaned after transportation. Railroad transportation should be prohibited slipping.
Operating precautions: strengthen the local exhaust. Operators must be specially trained and strictly abide by the operating procedures. It is recommended that operators wear self-absorbing filtering dust masks, chemical safety protection glasses and anti-static work clothes. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment.
Avoid generating dust. Avoid contact with oxidizing agents, acids, halogens, and chlorinated hydrocarbons. Take particular care to avoid contact with water. Operate disposal in nitrogen. Handling should be lightly loaded and unloaded to prevent damage to packaging and containers. Equip with appropriate varieties and quantities of fire-fighting equipment and emergency equipment for leakage. Empty containers may retain hazardous materials.
