| Product introduction | |
| Lead is a metallic chemical element, and its chemical symbol is Pb (Latin plum; Lead), with atomic number 82, is a non-radioactive element with the largest atomic weight. | |
| Properties of lead | Soft and malleable, low melting point, When it is just cut out, it is silvery and slightly blue. When it is exposed to the air, it will lose its luster and become dark gray. It has the advantages of high corrosion resistance, difficult penetration of X-rays and γ-rays, good plasticity, etc., and is often processed into plates and pipes. Widely used in chemical industry, cable, storage battery and radiation protection and other industrial departments. Lead is also a toxic heavy metal, which has been listed in the list of toxic and harmful water pollutants. |
| Use of lead | Lead is mainly used to manufacture lead storage batteries; Lead alloy can be used for casting type and soldering; Lead is also used to make protective equipment for radioactive radiation and X-rays; Lead and its compounds are toxic to human body and can accumulate in human body. Lead is used as building materials, in lead sulfate batteries, as bullets and shells, and also in welding, trophies and some alloys. Lead can also be made into flower bombs (also known as dummies). |
| Lead material | |
| lead sheet | Generally, lead material is rolled into a thin lead plate with a width of less than 3.6m and an arbitrary thickness, and the weight of the lead plate is 0.4mm thick. As a structural material, lead plate is a very important corrosion-resistant material in chemistry and related industries, which is mainly due to lead's corrosion resistance to various corrosive environments. Of course, it can also be used as building structural materials, such as roof anti-corrosion boards and floors in bathrooms. Lead plate is usually coated with a layer of asphalt when it comes into contact with cement. As a shielding layer for X-rays and γ-rays, it is a familiar application. Taking advantage of the excellent shock absorption and sound insulation performance of lead, a large number of lead plates are also used in shock absorption and sound insulation. For example, steel and lead shock absorbers installed under the foundation of buildings to hinder vibration transmission; Pure lead can absorb most of the vibration energy released during an earthquake. In an earthquake in Japan in recent years, this kind of shock absorber has been tested. |
| lead tube | Lead pipes in lead materials are also a major aspect, which are widely used in chemical industry and drainage pipelines. The seamless tube is extruded with chemical lead or lead containing 6% antimony. Tubes with diameters ranging from thin tubes to 300mm or more are used in production. |
| Wire mesh lead | In the lead materials for building, besides lead plate, pipe and solder, there is also lead mesh cloth for plugging; A considerable part of the above-mentioned lead-tin solder, fusible alloy (alloy of lead with tin, bismuth, cadmium, indium, etc.) with low melting point is almost all wire. The lowest melting point of the latter is below 100ºC, which is used for automatic arc extinguishing, electric fuse, boiler plug and so on. |
| Lead casting material | The main casting materials of lead are bearing alloy and lead alloy; Casting products include bearings, type plates, counterweights, sealing washers, warheads, ballast counterweights, and even integral castings of radiation protection layers of large nuclear power plants. |
| Lead composite material | A lead sheet is sandwiched between two tin sheets and rolled into a tightly bonded Sn-Pb-Sn composite foil with a thickness of 0.01mm or less, which is commonly called "lead foil". Used in the construction industry to prevent moisture, or as anti-oxidation foil for grapes and champagne bottles. Some are also used in the electronics industry. This "lead foil" is mass-produced and widely used abroad. However, there is a gap in production and application in China. Of course, the more common and widely used lead composite material is made of lead combined with stronger materials, and its performance is better than that of the single two materials. Lead can be compounded with steel, concrete, wood, brick or other appropriate materials. The structural composite material has excellent corrosion resistance and high strength. Although the strength of the composite of lead and plastic is slightly lower, the composite material has excellent sound insulation performance. |
