Description

Lead is a clear, slightly yellowish liquid. When drying at low temperatures (temperatures below 10. C), it is the most widely used dryer. It is also a deep and auxiliary dryer that makes it flexible.

Lead in sulfur-contaminated air produces black lead sulfide, which darkens and reduces the gloss of the film. Its presence also poisons the dryer, and the best alternative is a mixture of dryers under the conjunctiva and calcium. In the paint and resin industries, ink and casting are widely used, with the explanation that in aluminum paints It is better not to use it because it is laminated and in smoke and steam resistant paints.

What is lead?

Lead is one of the elements of the periodic table, lead is one of the metals and its atomic number is 82 and its scientific symbol is Pb, which stands for its Latin name, Plumbum. This element is one of the many elements in the Earth’s crust, but its abundance is less than copper and zinc, and it is the 31st most abundant element in the Earth’s crust. It is a silvery-white-white color that changes to gray when exposed to air. This discoloration is due to the formation of an oxidized layer of lead due to exposure to humid ambient air.

Properties of lead?

Lead is a highly flexible metal and a weak conductor of electricity, does not absorb radiation and is resistant to corrosion, so it is used to transport and produce many acids. Oxidation of the lead surface in the presence of air protects the rest because it creates a layer of carbonate on the surface of the those, which reduces the reactivity after formation. Its density is 11.34 grams per cubic centimeter. Its atomic mass is 207.2 and its melting point is 327 and 1755 degrees Celsius, respectively.

Lead applications?

Due to its good resistance to sulfuric acid, lead is very popular as a container for producing or carrying this material. Also, in ancient times, it was widely used in construction and production of ceramic paints and glazes and water piping.

Its use in plumbing has been banned in the United States since the 1990s due to its destructive effects on human health, and is not so widely used in plumbing today. In the paint industry, it can be said that 50% of the old paints were made of lead. It was banned in the United States from 1978 and in the 1960s and 1980s in the United Kingdom.

Therefore, it is better to avoid shaving or sanding on surfaces with old paints, because the resulting dust contains large amounts of lead. Also, burning wood surfaces that contain old paint also causes the particles of this substance to spread in the air. It was also used in gasoline and diesel, which have been banned in the United States since 1986 and in the European Union since 1999. It is also used in car batteries.
