What are the effects and functions of charcoal? The efficacy and function of charcoal

Metallurgy: Charcoal is used more in the industrial field, usually in non-ferrous metals and crystalline silicon.

In production. Pig iron smelted from charcoal.

Generally, it has a fine-grained structure and contains few impurities, which is suitable for the production of high-quality steel. In the production of non-ferrous metals, charcoal is often used as a surface flux to form a protective layer.

Charcoal has numerous holes in it, and these holes have the function of adsorbing various substances and emitting adsorbed substances, so people use it as a dehumidifier. When wet, charcoal absorbs moisture, and when it dries, it emits the absorbed moisture, making it an excellent humidity regulator. In addition, charcoal can also eliminate odors and harmful substances in the room.

Precautions for the use of charcoal.

When doing experiments on charcoal burning in oxygen, it is best to use long strips of charcoal. You can start with tweezers.

Or hold the charcoal in a crucible, heat it until it turns red, and then put it in an incendiary spoon. The red-hot charcoal should be slowly placed into a gas cylinder containing oxygen from top to bottom, and if it reaches the bottom of the bottle at the beginning, the carbon dioxide produced by the charcoal burning.

The oxygen in the middle and upper part of the bottle will be discharged, and the charcoal will not burn smoothly.

Because charcoal is alkaline, direct use is not good for plants that like acidic environments, so it is necessary to rinse with water before use, and wash away the alkaline substances before use.

The above content refers to Encyclopedia - Charcoal.

Of course, charcoal is used for burning! What you want to ask should be activated carbon, activated carbon is a kind of purification product that everyone uses more, it can be used to adsorb formaldehyde, but when using, it should be replaced regularly, because it will have adsorption saturation, and if it is not replaced in time, it is easy to produce secondary pollution. In fact, there are many ways to remove formaldehyde, and I will share a few more with you below.

1. Wise Stone.

It is currently a relatively cost-effective formaldehyde removal product, its advantage is that it can be decomposed into water and carbon dioxide at the same time of absorbing formaldehyde and harmless substances to the human body, because of its decomposition characteristics, so that it will not appear adsorption saturation and indoor secondary pollution, and suitable for various types of environmental use. In addition, its removal rate is also dozens of times that of traditional adsorbent materials. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

2. Ventilation.

If you want to eliminate formaldehyde in the house as soon as possible, you can put a floor fan at home after the decoration is completed, and open the window for ventilation at the same time, if the outdoor wind allows, the fan can increase the flow speed of indoor and outdoor air, reduce the indoor formaldehyde content, and speed up the release of formaldehyde, it may be the most effective and low-cost way

3. Plants.

Plants are the best products provided by nature to remove formaldehyde, and the more respected ones on the market are: pothos, spider plant, ivy, and aloe vera. These plants are a combination of beauty and talent, both to decorate the home and to purify the air.

4. Formaldehyde remover.

Under certain conditions, formaldehyde scavengers react chemically with formaldehyde to produce other substances that are not harmful to health, so as to reduce the concentration of formaldehyde in the room. But it's also a chemical in its own right, and if used incorrectly, it can be another source of pollution indoors.

Fifth, high temperature.

We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that a large amount of formaldehyde gas can be volatilized, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire.

In fact, in addition to formaldehyde, everyone wants to control formaldehyde simply, but the process is generally very bumpy, so choosing the right method to remove formaldehyde is the key.

Metallurgy: used in the production of non-ferrous metals and crystalline silicon. In the production of non-ferrous metals, charcoal is often used as a surface flux to form a protective layer.

Charcoal brick: Charcoal brick is a kind of smokeless brick when burning, which has the advantages of hygroscopicity and low water absorption, and is made of charcoal to facilitate transportation.

Carburizing agent: charcoal is used as raw material to add contact agent to make carburizing agent. Carburizing agent is an additive used in the metallurgical industry, and steel products with good toughness are carburized.

The uses of charcoal include: for metallurgy, to make charcoal bricks, for making carburizing agents, for making sulfur dioxide, for purifying indoor air and absorbing moisture.

Charcoal is a fuel made by firing wood through a special process. Most people just use charcoal for heating, but in fact, charcoal has other uses, so what are the uses of charcoal? Let's find out.

01 Metallurgy.

Charcoal can be used in the production of non-ferrous metals as well as crystalline silicon. Pig iron smelted by charcoal has the advantages of fine structure and less impurities, and is suitable for the production of high-quality steel.

02 Charcoal bricks.

Charcoal can be made into charcoal bricks, which are smokeless fuel bricks when burning, which will not produce carbon dust and have the advantages of strong hygroscopicity, specific gravity and high calorific value.

03 Carburizing agent.

Carburizer is an additive used in the metallurgical industry, and carburizing is generally required for the manufacture of steel products. Of course, the carburizing effect of simply using charcoal is relatively poor, and charcoal is often used as raw material and then a certain amount of contact agent is added to make carburizing agent.

04 Sulphur dioxide.

The production of sulphur dioxide requires the use of charcoal, which is also a high-quality raw material for the production of sulphur dioxide. Of course, in the production of chemical products, there are also certain requirements for the use of charcoal. Generally, charcoal is required to be hard, large in volume, less moisture, and high in carbon content.

05 Purify indoor air and absorb moisture.

Charcoal can absorb toxic gases in the room, such as formaldehyde. When returning to Nantian, put a pot of charcoal indoors to absorb the humid air indoors.

Burning – heating, heating, cooking.

Dehumidification - make a pocket with a cloth, put a certain amount of charcoal, and place it indoors, which can absorb moisture in the air and achieve the effect of indoor dehumidification and drying.

Filtration, such as activated carbon in the snout at the tip of a gas mask, can adsorb impurities from the outside air.

Hello Answer! Carbon is a non-metallic element with the element symbol CIt means "coal, charcoal". Carbon is a very common element that is widely found in the atmosphere and crust in many forms. Can be used as fuel.

Carbon is indispensable to all known living systems, without which life would not exist. The main economic use of carbon other than food and wood is in the form of hydrocarbons, most notably oil and gas. **Fractional distillation process used by the petrochemical industry to produce other commodities, including gasoline and kerosene, in refineries.

Cellulose is a naturally occurring carbon-containing polymer.

Hello! Carbon can also be alloyed with iron, most commonly carbon steel; Graphite can be mixed with clay to make pencil leads for writing and painting, graphite can also be used as a lubricant and pigment, as a molding material for glass manufacturing, for electrodes and electroplating, electroforming, brushes for electric motors, and as a neutron deceleration material in nuclear reactors.

Uses of charcoal.

1.Metallurgical industry.

In the past, charcoal was used to smelt iron ore, and the structure and mechanical properties of pig iron smelted from charcoal and coke were still different even though the chemical composition was the same. The pig iron smelted by charcoal generally has the characteristics of fine-grained structure, tight casting, no cracks, and the pig iron produced with charcoal contains few impurities, which is suitable for the production of high-quality steel.

In the production of non-ferrous metals, charcoal is often used as a surface flux, when the non-ferrous metal is melted, the surface flux forms a protective layer on the surface of the molten metal, so that the metal is separated from the gas medium, which can not only reduce the splash loss of the molten metal, but also reduce the saturation of the gas in the molten metal. A large amount of charcoal is also used in the production of crystalline silicon, and the charcoal used in the production of crystalline silicon should not contain green charcoal heads and excessive ash.

2.Manufacture of carburizing agents.

All steel products that require high surface hardness and wear resistance, and good toughness in the center, should be carburized. The carbon-containing mixture used to carburize steel products is called a carburizing agent. Charcoal alone has a poor carburizing effect.

Therefore, charcoal is often used as raw material, and then a certain amount of contact agent is added to make carburizing agent.

3.Carbon disulfide production.

Charcoal is the best raw material for making carbon disulfide, and the charcoal used to make carbon disulfide should be hard, large in volume, small in ash and moisture, and high in fixed carbon. It takes about tons of charcoal to produce 1 ton of carbon disulfide.

4.Pressing of charcoal bricks.

Crushed charcoal is inconvenient to transport, and the use is also limited, and the method of pressing charcoal bricks can turn small value crushed charcoal into high-quality fuel. Charcoal bricks have the advantages of low hygroscopicity and water absorption, high specific gravity and calorific value, and have high mechanical strength in the process of use. Calcined charcoal bricks are smokeless and do not produce charcoal dust when burned.

Charcoal bricks can be used in metallurgy, mobile gasifiers, etc.

1. Charcoal. Charcoal is a dark brown or black porous solid fuel left over from incomplete combustion of wood or wood raw materials or pyrolysis in the absence of air.

Charcoal is an impure amorphous carbon that retains the original structure of the wood and the residual tar in the pores. Charcoal was used for the smelting of bronzes of the Shang Dynasty and iron tools of the Spring and Autumn Period and the Warring States Period in China, and its hygroscopicity was used to observe climate change.

2. Ink. Ink is a liquid containing pigments or dyes that are used in writing or drawing. The earliest inks were dyes made from metal, walnut shells, or seeds, or inks from aquatic animals such as fish and octopus. The ink in China is carbon ink.

3. Black beans. Black soybean is a leguminous soybean (scientific name: glycine max (L.).

The protein content of black beans is 36%, which is easy to digest and is of great significance to meet the body's protein needs; The fat content is 16%, mainly containing unsaturated fatty acids, and the absorption rate is as high as 95%, which not only meets the body's needs for fat, but also has the effect of reducing blood cholesterol;

Black beans are rich in vitamins, egg yolk, melanin and lecithin and other substances, of which B vitamins and vitamin E are very high, with nutritional health effects, black beans are also rich in trace elements, to maintain the integrity of the body's functions, delay the aging of the body, reduce blood viscosity, and meet the brain's demand for trace substances are essential.

4. Black sesame seeds.

Black sesame (Semen Sesami Nigrum) is the black seed of sesame in the family Flaxaceae, also known as flax, oil hemp, Jusheng, fat hemp, distributed in Anhui, Hubei, Guizhou, Yunnan, Guangxi, Sichuan and other places.

Black sesame seeds contain a lot of fat and protein, and also contain nutrients such as sugars, vitamin A, vitamin E, lecithin, calcium, iron, chromium, etc. It has the effect of strengthening the stomach, protecting the liver, promoting the growth of red blood cells, and can increase melanin in the body, which is conducive to hair growth.

5. Black fungus.

Black fungus [auricularia auricula( hook.]underw] also known as black cabbage, fungus, cloud fungus, belongs to the family of fungus, fungus, is a precious medicinal and edible colloidal fungus in China, and is also recognized as a health food in the world.

China is the hometown of black fungus, and the Chinese nation recognized and developed black fungus as early as 4,000 years ago in the Shennong era, and began to cultivate and eat. There is also a record of the consumption of black fungus at the emperor's banquet in the Book of Rites. At present, black fungus is cultivated in the northeast, north, central, southwest, and coastal provinces of China.
