What is the harm of lime to the human body Is lime wall harmful to the body

Lime is an inorganic compound fired from limestone, which crumbles when exposed to water, turns into calcium hydroxide, and emits a large amount of heat. It is generally processed into lime powder or lime water for use as a building material. In some construction sites and farm yards, lime is often piled up in the open without covering, or lime ponds are not fenced.

These places are places where children and teenagers like to play, so some people are prone to fall into lime pools or lime piles when chasing each other or playing hide and seek, burning out the conjunctiva and cornea, and in severe cases, causing blindness. There are also some children who do not understand the serious dangers of lime, and throw lime at each other when playing, once it hits the eye, it can cause injury. Therefore, when playing, teenagers should try to avoid places where lime and other harmful items are stored, and do not play by the lime pool, especially at night.

The dangerous and uncivilized behavior of throwing lime at each other should be resolutely abandoned.

Once lime accidentally falls into the eyes during games or labor, you should immediately go under the faucet or fill it with water to rinse it repeatedly, and then go to a medical institution**, so as to reduce the damage of lime to the eyes and not cause blindness. However, if quicklime falls into the eye, the lime particles should be carefully removed from the eye before rinsing with water. Otherwise, the quicklime will be heated by water, which will aggravate the injury.

Raw materials for building materials such as cement, bricks, and lime contain radioactive radium. After the building is completed, radon and its progeny, the decay of radium, will be released into the indoor air and enter the human respiratory tract, which is one of the most common causes of lung cancer. The radon content in outdoor air is about 10bq m3 or less, and indoor can exceed dozens of times.

The excess death toll from lung cancer caused by radon and its progeny in the United States is 120,000.

Lime powder itself does not contain formaldehyde, however, in the actual construction, some workers in order to build fast and good effect, it is possible to artificially add glue to the product. For example, 802 glue contains formaldehyde. The problem of contamination does not come from the product itself, but from non-standard construction.

It will not cause harm to the body, because the composition of hydrated lime is calcium hydroxide, and quicklime is calcium oxide, neither of which is volatile.

However, it is important to note that the lime powder does not fly, once it flies and spreads into the air, it is no different from dust, and it will cause some damage to the body if it enters the body through breathing. Secondly, if there are children in the house, be careful not to let the children eat by mistake.

Hello, harmful.

The main component of lime is calcium oxide, if you eat lime, it will combine with the water in the human body to generate calcium hydroxide, and produce a lot of heat, which is enough to make the water boil, and if such a temperature appears in the human body, it will make people have a very strong burning feeling, which will be fatal.

Answer: Hello and kiss, because lime powder is very common in our lives, so it is easy to inhale into the body in the process of use, if you inhale too much lime powder in ordinary times, it will bring serious harm to human health, and the most common is prone to some respiratory diseases.

Lime can be used in corn tofu and can be used as a seasoning, which is an ancient hair of the Tujia along the river, and almost every Tujia along the river eats it.

There is no problem with small use, downstairs said that contact with water, produces calcium hydroxide, releases heat and makes water boil, you know, you have a thing called stomach acid.

Answer: Hello and kiss, because lime powder is very common in our lives, so it is easy to inhale into the body in the process of use, if you inhale too much lime powder in ordinary times, it will bring serious harm to human health, and the most common is prone to some respiratory diseases.

Excessive consumption is harmful. A small amount is not harmful to the body, because lime water is alkaline, and the stomach is hydrochloric acid, which is acidic. Neutralization of the two is not a major harm to the body.

But you can't eat too much lime, too much will make you feel stomach discomfort, in this case, you have to go to the hospital for examination. Lime powder is a white powdery substance with calcium carbonate as the main component. It has a wide range of applications, the most common being calcium carbonate in the construction industry, i.e. for industrial use.

The other is food-grade calcium carbonate, which is widely used as a common calcium supplement.

Production process: The original lime production process is to lay limestone and fuel (wood) in layers, and calcine it for a week. In modern times, mechanized and semi-mechanized vertical kilns, rotary kilns, boiling furnaces and other equipment are used for production.

The calcination time is also shortened correspondingly, and it only takes 2 to 4 hours to produce lime with rotary kiln, which can improve the production efficiency by more than 5 times compared with vertical kiln production. Energy-saving processes and equipment such as cross-flow, double-slope and oil-fired circular vertical kilns and short-rotary kilns with preheaters have also expanded the fuel to coal, coke, heavy oil or liquefied gas.

Packed in plastic woven bags lined with polyethylene plastic film bags, each bag has a net weight of 25kg. It should be stored in a dry warehouse. Protect against moisture.

Avoid co-storage and mixed transportation with acids. Protect from rain when transporting. In the event of a fire, it can be extinguished with water, sand or a general fire extinguisher.

Physical properties: Fine white powder. Relative density. Calcium carbonate is formed by absorbing carbon dioxide in the air.

Soluble in acid, ammonium salt, glycerol, slightly soluble in water, insoluble in alcohol, strong alkaline, corrosive effect on **, fabrics, utensils and other substances. Its aqueous solution is commonly known as lime water.

Yes, the lime in the lime wall is easy to air dry to form lime dust, which is harmful to the human respiratory system.
