Now there s a kind of charcoal that is said to be used in place of mothballs, and what s the differe

Mothballs are chemical and charcoal is physical.

The difference is not very big, hard guess what Wu Liquid wants to say should be the current charcoal content is slightly higher, after all, the concentration of carbon dioxide in the air is higher than before, and the carbon-containing substances synthesized by plant photosynthesis are naturally more.

Now there are two purposes for drilling in the middle of charcoal: one is to fully burn, and the other is of course to save materials, and the remaining cinders from drilling can be made into other by-products (such as printer toner, stainless steel charcoal, etc.), and good looks are secondary.

The boss's words seem to be untenable, the combustion of charcoal in the air must include full combustion and insufficient combustion, carbon dioxide is produced in the case of full combustion, and carbon dioxide is produced by insufficient combustion. Although the perforated charcoal increases the contact area between the charcoal and oxygen, it is absolutely impossible to fully burn, that is, carbon monoxide will definitely be produced, and it can only be said that the amount of carbon monoxide produced may be much less than the previous charcoal.

The original charcoal is to put the firewood into the dug carbonization pool, and close the pool after ignition to prevent it from entering a trace of air, so that the firewood is slowly burned and carbonized in an oxygen-free state, but the carbonization time is relatively long, and it is very difficult to grasp the lead group when it is closed and out of the kiln, and it is easy to burn, that is, it is burned into ash, and the efficiency is also low. Ordinary people can barely use it themselves, but if they are used by more than one person, it is far from enough. There is another reason, and it is also a very important reason, because of the lack of resources, the state has now banned the cutting down of trees, and generally for the mode of soil carbonization, Wang Hong must cut down some thick branches to carbonize, so that there is a conflict with the country's policy, on the one hand, the country is not allowed to cut down, there is a mechanism of charcoal, with sawdust, rice husks, cotton stalks, peanut shells, shavings, wood scraps to make charcoal.

In the whole process of charcoal burning, there is always dealing with heat, that is, a part of the energy must be consumed to improve the economic value and use value of charcoal.

Carbonization is an important part of machine-made charcoal. The carbonization process is at the heart of the technology used to make machine-made charcoal. It's like building a building.

A good raw material is the foundation of the building, which is the part underground. The carbonization technology in the carbonization process is the above-ground part of the building. Carbonization is divided into three stages: low-temperature trapping and excitation, high-temperature calcination, and cooling and cooling.

The burner has about 8% water when it enters the carbonization furnace, which is the enemy of carbonization. Because the mechanism salary stick is most afraid of moisture, the moisture in the salary stick will seriously affect the carbonization quality. Therefore, the timing of the discharge of the tide is essential.

Tide discharge time is essential. The tide discharge time is generally 10-15 hours for the soil kiln and the hour for the mechanism kiln, and the long heating time can prevent the damp cracking of the salary rod and ensure the carbonization quality. When the furnace temperature rises to 300 degrees, a large amount of combustible gas can be generated in the furnace.

Each catty of raw material can theoretically produce three cubic meters of methane gas. These gases can be used to heat up the furnace. Discharge the heat source available for drying above 400 degrees, which is the heat preservation and calcination stage, which needs to be sealed without oxygen and closed fire, which can be taken from spontaneous combustion cooling or water cooling cooling.

After the charcoal is out of the kiln, it is necessary to ventilate the charcoal before the charcoal is released to prevent carbon dioxide poisoning. The charcoal out of the kiln should be left outdoors for more than 8 hours. Prevent the recurrence of ashes and fires.

Camphor blocks are generally made from synthetic brains, and some are made from camphor extracted from the trunk, leaves, roots, and branches of stick trees. The insecticidal power of the camphor block is greater than that of the sanitary ball, and it will not leave a ring mark on the clothes after volatilization, so it is more suitable for the storage and moth prevention of woolen fabrics.

Mothballs are divided into natural mothballs and synthetic mothballs.

Synthetic mothballs are organic compounds, and most of the mothballs containing naphthalene are white, have a pungent odor, and sink in water; It is classified as a carcinogen.

Natural mothballs are smooth, colorless or white crystals with a fragrant smell that float in water. Natural mothballs, also known as stinky beads, are used to prevent insects, moths and mildew, which are originally aromatic organic compounds extracted from the branches and leaves of the camphor tree. It is also used in medicine, spices, etc., and is used as a cardiotonic in medicine.

There is no difference Generally speaking, this is used to kill insects, and it is put in the wardrobe for fun to kill insects, thank you for adopting.

It should be the difference in shape! o( o, but insect repellent is good, but the smell is not good. Moreover, it is better not to take it out whole and put it in the closet, just make a few small holes in the bag. (*

Hello, the ingredients are all the same, but different shapes can sometimes be used in different places.

Mothballs also have a moisture-proof effect, but they also have the effect of wardrobe insects, which are not too expensive

If the house is damp, it is recommended to open the door and open the window for ventilation, and now the sun is also good, you can take out the bedding to dry

This is much stronger than putting charcoal, limestone, mothballs

If it's not convenient, you can go to the store and ask if there's a better way.

It can be heated and dehumidified with an electric blanket.

Charcoal: It can absorb odors and moisture. There are general farmers' markets.

Limestone: can disinfect, kill insects and absorb moisture. It is building material, and there is a general interior material store.

Mothballs: Insecticidal. The average supermarket should have.

Six functions of bamboo charcoal: 1. Purify the air.

2. Adjust the temperature.

3. Anti-mildew and antibacterial.

4. Soil improvement.

5. Absorb electromagnetic radiation.

6. Release far-infrared rays.

Nine functions of bamboo charcoal: 1. Adsorption of harmful gases such as formaldehyde, ammonia, benzene 2. Release of far-infrared rays.

3. Release negative ions.

4. Release trace elements.

5. Control the reproduction of microorganisms.

6. Regulate the growth of crops.

7. Insecticide and sterilization.

8. Antioxidant.

9. Electrostatic shielding and anti-electromagnetic radiation.

Bamboo charcoal packets are natural, and mothballs are chemically synthetic. The effect is about the same.

Bamboo charcoal packets can also absorb moisture, prevent mildew and sterilization, but they should be dried frequently. There are not many people who use mothballs now, and the ingredients are harmful to the body.

Bamboo charcoal adsorbs taste, but mothballs are insect repellent by taste.

Bamboo charcoal packets can absorb water and absorb harmful gases, and mothballs are mainly used to prevent insects in clothing.

It's not good, because the charcoal itself adsorbs odors, and it will become ineffective because it quickly absorbs enough of the smell of mothballs, and at the same time, part of the smell of mothballs is absorbed, and the medicinal power is also reduced.

It's better not to

Activated carbon has an adsorption effect because its molecular structure is a lot of voids, adsorbing toxic gases, macromolecules, etc. Don't let him come out inside, like a sieve, the particles sublimated by mothballs are adsorbed by carbon

This is equivalent to putting nothing at all.

Analysis at the high school level.

Don't be surprised, give points.

1. **Different.

Activated carbon is a product obtained after the activation of wood, coal and other materials, and the activated carbon has to go through the activation, pickling and drying stages in addition to the carbonization process.

Charcoal is a dark brown or black porous solid fuel left over by incomplete combustion of wood or wood-based raw materials or pyrolysis under the condition of isolated air, and charcoal only goes through the carbonization stage.

2. The main ingredients are different.

More than 80%-90% of activated carbon is composed of carbon elements, in addition to carbon elements, it also contains two types of admixtures: one is chemically bound elements, mainly oxygen and hydrogen, which are left in the carbon due to incomplete carbonization, or in the activation process, foreign non-carbon elements are chemically combined with the surface of activated carbon.

The main component of charcoal is carbon, the ash content is very low, 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 depends on the final temperature of carbonization. Charcoal has a large number of micropores and transition pores, so that it not only has a high specific surface area, but also produces carbon dioxide from complete combustion with oxygen, and carbon monoxide from incomplete combustion with incomplete combustion.

3. Different uses.

Activated carbon has a large adsorption capacity for organic matter, and has been widely used in advanced wastewater treatment. Activated carbon is also used in the decolorization and refining of chemical catalysts and carriers, gas purification, solvents, and greases. Activated carbon is often used for adsorption to remove indoor pollution, furniture odor removal, car deodorization, etc.

Charcoal can be used as a reducing agent for fuel and electric furnace smelting, and is often used as a raw material for carbon disulfide and activated carbon in the chemical industry. It is used as fuel in biscuit factories, smelters, etc., and is also used for water filtration, decolorization of liquids, and preparation of black gunpowder. It is also used in grinding, painting, makeup, medicine, gunpowder, carburizing, powder alloy and other applications.

From the point of view of the elemental composition and structure of the substance: there is not much difference between activated charcoal and charcoal. That is, they are all carbon back elements, and they are all loose and porous.

The difference between activated carbon and general charcoal is that activated carbon is more loose and active (adsorption capacity) than general charcoal.

Activated charcoal is made from charcoal. However, the activated carbon made of general charcoal is not very active, and the charcoal usually used to make activated carbon is made by high-temperature carbonization of the shells of nuts such as walnut shells and coconut shells, and then this charcoal is treated with high-temperature water vapor to remove the oil stains and make the pores in the charcoal loosen up. In this way, the charcoal is made into activated carbon.

This is simply a point of view.

Charcoal utensils. Du body use, see zhi

According to our ancient dao poem "Charcoal Seller".

In activated carbon, there are several types of raw materials for production, one of which is wood-based activated carbon. Wood activated carbon is made by further processing after wood carbonization, such as activation, pickling, drying, etc.

Activated carbon is not used for heating and heating, but for filtration and purification.

The two are worlds apart in terms of use.

Activated carbon is a type of carbon with multiple pore sizes.

According to the adsorption point of BAI activated carbon, activated carbon is mainly used to remove ZHI pollutants in water, decolorize, filter and purify liquids and gases, and is also used for air purification treatment, waste gas (such as gas benzene in the chemical industry), precious metal absorption and refining (such as absorption).

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.

The difference between charcoal and activated charcoal in terms of use and nature.

Charcoal adsorption will be saturated and ineffective, it is recommended to remove it with activated carbon, among which the better is coconut carbon, coconut vitamin carbon is a popular formaldehyde removal material in foreign countries in recent years, with coconut shell as raw material, after high temperature activation and carbonization treatment, it is also a new type of activated carbon containing photocatalyst and carbon fiber, and the adsorption capacity of organic gas is 5 times that of ordinary activated carbon, and the adsorption rate is faster.

Activated carbon has activity and can adsorb harmful substances in the air, while charcoal is generally only used for combustion and has no effect at all. In addition, Ye Guang mud and activated carbon work similarly, but they are better than activated carbon in purifying the air!
