Battery hazards and handling methods

1, the battery structure, and classification:
Now I come to give us a presentation Battery Bar: The Hp 6735s battery is a kind of chemical energy directly into electrical energy. It can be divided into non-rechargeable batteries and rechargeable batteries. Here we have to look at the structure of non-rechargeable batteries, mainly at three levels: first, the outermost layer of "skin" is also what we call the shell, and second, for the reaction of chemical substances, was shell encase the middle is the graphite electrode. When the chemical reaction into electrical energy by following the output of graphite electrodes to form the outer loop to form the circuit current: The battery is working. Is divided into non-rechargeable batteries: nickel metal hydride batteries, nickel-cadmium batteries.
Second, the hazards of waste batteries:
When the battery's internal chemical reaction complete, the battery can no longer be powered, and has become a waste batteries, usually people will readily lose one, and then bought another one new. Most people would say that this is a normal mile. But they did not expect, just below that gestures, but also in the destruction of their homes - the Earth. Some people may ask: "It's that one little thing for the planet, able to do what is great! Also said that what is destroyed?" Batteries do not seem to be as destructive, but it can not all see things at face value. Waste contains large amounts of heavy metals inside the battery mercury, cadmium, manganese, lead. When the waste batteries from sun and rain corrosion of the surface of the cortex, in which the ingredients will penetrate into the soil and groundwater, once people eating contaminated land productivity of crops, or by drinking contaminated water, these toxic heavy metals will enter person's body, slowly deposited on the grave threat to human health! One measurement of a battery, according to rot in the soil can make one square meter of land loss of use value; a button button Hp 6720 battery can contaminate 600,000 liters of water, equivalent to the amount of drinking water a person's life. The nearest people to the world's five billion dollars a month per person lost a battery, one-year cumulative 60 billion batteries, the destructive power of the earth can be said is a great, and its effects on human health risks is more difficult to imagine the consequences of , and, according to statistics, every year, Beijing spent batteries and mercury into the natural environment has reached 29.6 tons, this number can not help but frustrating. So used batteries can not be arbitrarily discarded. In the battery recycling, countries attach great importance. In addition, the developed countries, production of sub-types of zinc-manganese battery is a mercury-free batteries. The developed countries do not allow imports of mercury-containing batteries. Therefore, China's mercury batteries can not enter Europe and the United States developed regions.
Third, the handling of used batteries:
Disposal of waste batteries is also available from the structure of the battery to start, first, the surface of the skin, its main ingredient is zinc. In the third-year experiment has such an experiment:
1, using discarded zinc batteries leather to take zinc sulfate crystals.
Experimental supplies: beakers, metal framework sets (with hoops), alcohol lamp, evaporating dish.
Dilute sulfuric acid, zinc dry skin.
Experimental steps:
⑴, the dry skin surface of the zinc impurities removed years later put them in beaker.
⑵, poured into the beaker amount of dilute sulfuric acid, to the degree of immersion of zinc skin until the skin of zinc dissolved.
⑶, the reaction solution after filtering.
⑷, the filtrate into the evaporating dish, evaporating dish on the metal Hp 6700 battery framework to Taiwan's hoops, and with the kerosene lamp, a heated. Precipitation of more crystals to be evaporating dish stops heating, evaporating dish using the waste heat to the filtrate evaporated, the recovery of zinc sulfate crystals placed in designated containers.
2, the second layer composition of chemical substances are complex, and only with advanced machinery in order to extract out the ingredients, and then made into useful things. Japan also had a such a factory, the battery recycling, from which extracted mercury, but a ton of used batteries can be extracted up to a few tens of kilograms of mercury, so the factory Finally, since investment is huge, small and bankruptcy. Although the Government encourages the development of this industry, but many manufacturers did not dare to put their lives at risk. Innermost layer of graphite electrodes is of course 啦.
3, the battery is the most inside graphite carbon rod, which also has a significant role in recovery after the great economic value. If you cut down some from the graphite powder, touch what it has creamy feel. This determines the nature of graphite it can be used as a lubricant. Some of the machines work at high temperatures on the graphite used as lubricant, for apart from application of graphite powder lubrication, but also applied to its high melting point can be high temperature in nature. In fact, graphite there is another important use, that is used to make synthetic diamonds, and perhaps few people know about graphite and Hp 550 batterydiamond carbon formed by a single quality, but their atoms arranged in a different order, leading to very significant differences between them to graphite heated to 20000C, pressurized to 5 × 109 Pa ~ 1 × 1010 Pa and catalyst conditions, one can create that shiny man-made diamond. People saw the beauty of diamonds, how they never think it was from that of graphite ink made of tetrahedrite tetrahedrite.
Germany has a Ke Sima President, working in China for nearly 20 years, she and her friends regarded treatment of waste batteries back to Germany, in China, she only bought rechargeable batteries and mercury-free batteries. Henan Xinxiang in Tian Guirong tirelessly over the past year, on a voluntary basis to promote environmental awareness. Printed materials, hold lectures, financed a few million to buy 30 tons of waste batteries. It seems that we should also learn from them, do their duty. Therefore, recycling and disposal of used Hp 451086-361 battery batteries, not only to reduce its environmental pollution and harm to human, but also gives us a very good cost-effective
