What can the old battery replaced in the car do?
Treat waste batteries and extract valuable metals from them. Lead-acid batteries are commonly used in electric vehicles and belong to consumables. The service life of brand batteries is 1-2 years. Although lead-acid batteries have been listed in the national hazardous waste list, there is no mandatory recycling. The recycling of waste batteries belongs to the recycling and processing industry, with high cost and heavy pollution, which is limited by technology and conditions.
At present, only waste batteries are recycled and sealed to prevent environmental pollution. Some lead smelting workshops and waste collection stations buy these waste lead-acid batteries. They don't have processing conditions. After extracting valuable metals, they dump them at will, which will seriously pollute the environment.
Waste batteries or treated battery residues enter the water body, causing heavy metal pollution to the water environment; Dumping on the surface at will may pollute the soil environment and further affect plant growth. After solidification, it is stored in an abandoned mine, such as a factory in France, from which nickel and cadmium are extracted, and then nickel is used for steelmaking and cadmium is used for battery production.
The remaining waste batteries are generally transported to a special toxic harmful waste landfill, but this method is not only costly, but also wasteful, because there are many useful substances that can be used as raw materials.
Can I put 75% alcohol in the car?
No, alcohol is a flammable liquid. If alcohol must be put in, adequate safety measures should be taken and put in a sealed jar without leakage, pressure and impact.
Ethanol is an organic compound with the molecular formula of C2H6O and the structural formula of CH3CH2OH or C2H5OH, commonly known as alcohol, which is the most common monohydric alcohol.
Ethanol is a flammable, volatile, colorless and transparent liquid at normal temperature and pressure, and its toxicity is low, so pure liquid cannot be directly drunk. It has special fragrance and slight irritation; Sweet and spicy. Flammable, its vapor can form an explosive mixture with air and can be mixed with water in any proportion. It is miscible with most organic solvents such as chloroform, ether, methanol and acetone, and its relative density (d 15.56) is 0.8 16.
Ethanol is widely used. Can be used for manufacturing acetic acid, beverages, essences, dyes, fuels and the like. Ethanol with a volume fraction of 70%~75% is also a commonly used disinfectant in medicine, which is widely used in national defense chemical industry, medical and health care, food industry and industrial and agricultural production.
Precautions:
1. Avoid fire sources when using alcohol for disinfection. Avoid alcohol disinfection in places with open flames and high-temperature equipment such as kitchens, and do not spray alcohol directly on your body. Smoking is strictly prohibited when spraying.
2. The container and the upper cover must be closed immediately after each entry, and it is forbidden to open them.
3. When using alcohol for disinfection, avoid using a large amount of medical alcohol in a relatively closed small room, so as not to form high-concentration alcohol vapor, which may lead to fire or explosion.
