Charcoal strips are the easiest way to make charcoal using techniques detailed .

Since the charcoal strips are fired from willow branches, the method is rolled with paper, so the color is black, especially in landscapes with mountains and trees, as well as water features: it can be painted on a large area. Since charcoal strips are fired from willow branches.

In addition, there is easy to modify, and the texture is loose and soft. Of course, you can also draw close-ups. The spatial relationship is easy to open, which is conducive to the full expression of objects, rich hues, buildings, etc.

Western painters like to use charcoal strip sketches to collect information for the creation of landscape oil paintings, the advantages of charcoal strips to paint landscapes, suitable for painting large-scale works, can be saved, due to the adhesion is not high, gently patted. However, you can spray a layer of fixing glue, and charcoal strips with poor adhesion are the most suitable for drawing a long shot.

Charcoal strips are best for drawing distant vistas, especially landscapes with mountains and trees, as well as water features. Of course, you can also draw close-ups, buildings, etc. Western painters often like to use charcoal strips to sketch and collect materials for landscape oil paintings.

The advantages of charcoal strips for painting landscapes: it can be painted on a large area, and the overall tone is very convenient, which is suitable for painting large-scale works. Since the charcoal strips are fired from willow branches, they are black in color and rich in hue, which is conducive to fully expressing the object.

Spatial relationships are easy to pull apart. In addition, because it does not have high adhesion, it is easy to modify, and the method is to use a paper roll, gently patting, and the powder can be removed.

Disadvantages: Since the charcoal strips are fired with willow branches, the texture is loose and soft, and the adhesion is poor. However, you can spray a layer of fixing glue and you can save it.

1. How to make charcoal strips by yourself: use bamboo or other wood as raw materials, isolate the air and heat it until the wood is completely charred.

2. Most of the existing charcoal strips are made by direct carbonization of log strips. First of all, the early loss of trees is cut down, straight branches are selected, peeled and cut into wooden strips of a certain length, and the empty suspicion is cut into a number of small log strips, and then these small log strips are put into the high-temperature furnace, and the oxygen in the furnace is extracted and carbonized at high temperature, and finally the charcoal Lu Kai strips are made.

1. First of all, you need to be in a space where you can place a large area of firewood, that is, a fire kiln, because the charcoal in the countryside is generally used for your own home, so it will not produce charcoal in large quantities. When making charcoal, there can not be too much air flow, otherwise the charcoal will burn completely, but it needs some air flow, because the conditions of the kiln are very suitable, the iron pot above can block the air, and the vent below can ensure a certain air flow.

2. Then, you need to prepare some firewood, preferably a relatively large wooden stick, so that the charcoal collected is relatively large, and the number of uses can be more. It can also better ensure that the firewood will not burn completely, and the ignition materials should also be prepared after the charcoal raw materials are prepared to ensure the burning of firewood.

3. The next step is to ignite, first ignite the ignition raw materials, put them into the kiln, and then slowly put some small firewood into it, and then put the big wooden stick next to it, so that the fire slowly spreads over, and then wait for the wooden stick to burn slowly, this process will take a long time, don't worry.

4. When the wooden stick inside turns red, it means that the fuel on the outside has been burned almost, and it can be taken out to make charcoal, there can be many ways to make charcoal, you can take out the mahogany stick with props and put it into water to make charcoal, which is also the fastest one, and the residual temperature of charcoal will dry the dampness on the surface of the charcoal.

5. You can also choose to cut off the air to make charcoal, and it is a common way to place it in charcoal ash so that it cannot burn again. After a period of time, it can be taken out and placed in a container dedicated to the charcoal, so that the charcoal is ready to be rented.

6. If a large amount of charcoal is made in the countryside, then some professional containers are needed to burn charcoal, the principle is the same, while blocking some air, it is also necessary to maintain some air circulation, so as to get a large amount of charcoal, but this needs to completely cut off the air to make the red rod form charcoal, which is safer.

Problem description: How to make charcoal.

Xie Li Qixi: Zhang Side was sacrificed when the charcoal kiln collapsed when burning charcoal, at that time, which Xinling burned charcoal, that is, the trees were cut into sections, ignited in the charcoal kiln, burned to a certain extent, closed the charcoal kiln air entered, the waste heat continued to heat the wood dry distillation, the water and wood tar were boiled out, and the wood was carbonized into charcoal. This is similar to the past when families burned firewood and held charcoal.

At present, there is a method of processing charcoal using wood chips and other waste materials, pressing these waste materials into shape, heating them indirectly in a furnace for dry distillation, and carbonizing these raw materials into charcoal.

How much charcoal can be made from a cart of wood? After looking at the production process, it makes sense that charcoal is expensive.

Generally, it is formed by incomplete combustion of willow or other tree branches, or pyrolysis under the condition of air isolation, to form dark brown or black porous solid carbide

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. It is an impure amorphous carbon that retains the original structure of the wood and the residual tar in the holes.

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. In addition to being used as a living fuel, it is also used as a fuel for metal smelting, food and light industry, a reducing agent for electric furnace smelting, and a covering agent for metal refining to protect metals from oxidation. In the chemical industry, it is often used as a raw material for carbon disulfide and activated carbon.

In addition, it is also used in grinding, painting, makeup, medicine, gunpowder, carburizing, powder alloy and other applications.

According to the raw materials used for charcoal burning, it can be divided into: hard charcoal. It is mainly composed of hard broad-leaved woods such as Quercus and Quercus spp., and the secondary ones are Birch.

Broadleaf charcoal. Charcoal made from a mixture of hard and soft hardwood. Pine charcoal.

Charcoal fired from pine or other coniferous wood. In addition, there is bamboo charcoal fired with bamboo, and kernel charcoal fired from wood raw materials such as fruit husks and pits (coconut shells, peach pits). Charcoal collected from household stoves is commonly known as charcoal.

If the charcoal is crushed, mixed with an appropriate binder, and then laminated and roasted, it is made into laminated charcoal. According to the charcoal burning process, it is divided into white charcoal and black charcoal.

The main component of charcoal is carbon, in addition to hydrogen, oxygen, nitrogen and a small amount of other elements, the content of which has little to do with the tree species, mainly depending on the final temperature of carbonization. Charcoal is a hydrophobic substance, the ash content is within 6%, the pores account for more than 7% of the volume of charcoal, the specific gravity is generally, the calorific value depends on the carbonization conditions, generally about 8000 kcal kg, the reducing capacity of charcoal is greater than that of coke, so as to be used as a reducing agent and covering agent for metal smelting. Charcoal has a large number of micropores and transition pores, so that it not only has a high specific surface area, but also has good absorption performance after the tar substances in the pores are eliminated, so it is an important raw material for the preparation of activated carbon.

Used in medicine occupied.

For oral glucose occupancy.

Used in the food industry occupied.

Used for other aspects occupied.

The use of granular activated carbon in China is as follows:

It is used to synthesize fiber carriers for Champ's chop.

Used for PVC carriers occupied.

It is used for air and water purification.

It is used for synthetic desulfurization.

Used for other occupancy.

It is worth noting that the adsorption of activated carbon prepared by different methods will be different, and each has a certain scope of application, and the effect is not good if the use of Jianyouchang is improper.
