2. Lead compounds are used as raw materials for pigments, glass, plastics and rubber. Metal lead is widely used in manufacturing chemical and metallurgical equipment because of its excellent acid and alkali corrosion resistance.
3. Lead alloys are used as bearings, movable type gold and solder.
4. In addition, lead has developed some new uses, such as being used as a stabilizer of asphalt to prolong the service life of pavement; It is used to manufacture nuclear power plant shielding and nuclear waste storage tanks, high-power storage batteries for power sector load regulation, magnetohydrodynamic devices, etc.
The main products are:
1, lead-acid battery (referred to as lead-acid battery);
2. Cable sheath;
3. Chemical products;
Extended data
1. Lead is one of the three major heavy metal pollutants and a heavy metal element that seriously harms human health. The ideal lead content in human body is zero.
2. The human body usually brings lead into the human body by ingesting food and drinking tap water. 90% of lead entering human body is stored in bones, and 10% is distributed to all tissues and organs of the whole body with blood circulation, affecting the functions of red blood cells, brain, kidney and nervous system, and more than 30% remains in the body, affecting the growth and intellectual development of infants.
Because lead is cumulative poisoning, only when the lead content in the human body reaches a certain level will it cause discomfort to the body. Long-term intake of lead will cause serious damage to the body's blood system and nervous system, especially to children's health and intelligence. Irreversible influence;
4. Lead in industrial production is inhaled into human body in the form of lead dust (smoke). Occupational lead poisoning is mostly chronic poisoning, which has comprehensive symptoms of nervous system, digestive system and blood system in clinic.
