What is activated charcoal and where can I buy it

Activated carbon is also known as activated carbon black. It is amorphous carbon in the form of black powder or granules. In addition to carbon, the main components of activated carbon include oxygen, hydrogen and other elements.

Activated carbon is a porous carbon with low bulk density and large specific surface area due to the irregular arrangement of microcrystalline carbon and fine pores between the cross-connections, which will produce carbon structure defects when activated. Activated carbon can be used to adsorb harmful gases, filter out insolubility, and adsorb some solubility.

Decoration materials are sold at the store.

Activated carbon in detail:

Function: Interpretation of various decorative materials'Formaldehyde, benzene, radon, TVOC and other harmful people'The healthy gas has the function of adsorption and purification, and has obvious effect on the removal of various peculiar odors.

Uses: new homes, office buildings, hotels, air-conditioned rooms, toilets, entertainment venues, new furniture, automobiles'cars, etc.

Safety: physical adsorption, no toxicity and no secondary pollution.

How to use: Place 1 bag per square meter in the newly renovated room, and place a bag in each separate space of cabinets, cabinets and drawers. Two boxes for the new car. It is valid for 5-8 months after opening, and after 30 days of use, it will be exposed to the sun for 3-5 hours and reused.

The functions of industrial activated carbon are as follows: 1. It is used as a gas phase adsorbent. The well-developed microporous structure of activated carbon is used to adsorb harmful gases to achieve the purpose of air purification and odor removal.

There are many types of gases adsorbed by wood activated carbon, and the speed is fast, and most of the adsorbed saturated waste activated carbon can be regenerated. 2. It is used as a liquid-phase adsorbent. At the beginning, it was used as a decolorizing agent in refined sugar, and now it is mainly used in water treatment, including sewage treatment, water purification treatment, water quality regulation, and in the medical industry for decolorization and purification of pharmaceuticals.

3. Used as catalyst and catalyst carrier. In redox reactions, activated carbon is an ideal catalyst material. At the same time, activated carbon is an excellent catalyst carrier because it has a rich internal surface area and a well-developed pore structure, which is convenient for substances to enter the activated carbon and be attached to the surface.

Excuse me, just after painting latex paint, how much activated carbon do you need to put in a room of about 30 square meters? How long can I stay before I move in? Thank you!

Newly renovated houses to remove formaldehyde activated carbon is useful, but it is easier to saturate, and it needs to be replaced by frequent exposure boxes, otherwise it will cause secondary pollution, or you can consider combining other methods to remove formaldehyde together. The methods that can be used are as follows: 1. Ventilation, ventilation can release a large amount of formaldehyde released, and use some leafy mud to absorb and decompose.

Different from the material of activated carbon, it will not adsorb saturation, does not need to be exposed to the sun, and can decompose and adsorb formaldehyde for a long time. 2. You can also put some plants at home, such as spider plant, tiger tail orchid, ivy, aloe vera, etc., which can absorb some harmful substances such as formaldehyde to a certain extent. 3. You can put some grapefruit peel to taste.

How long does it take to move in after putting in activated charcoal? What is Ye Guangni and how to use it?

It is recommended to use activated charcoal for at least one month after check-in as well.

Ye Guangni is a new type of formaldehyde removal material.

Building materials market, charcoal carving shop, big supermarket, **, pat pat , all have.

Make your own activated charcoal in the following ways:

1. Make charcoal with firewood, then knock it into a small piece of charcoal of about 1cm3, put the small piece of charcoal into a clean fine nylon mesh bag, tie it to the mouth of the bag, and then put it into a household pressure cooker or medical pressure cooker containing 5% sodium carbonate solution.

2. Boil at high pressure for about 30 minutes to wash out the oil and dredge the micro holes in the charcoal. To prevent the charcoal from floating on the sodium carbonate solution, a clean stone can be tied to the outside of the nylon bag and fall down.

3. After boiling, rinse the charcoal twice with water to remove the oil, then put it into 5% sodium carbonate solution and boil it at high pressure for about 30 minutes, take it out and rinse it three times with about 80 water to wash off the oil and a small amount of sodium carbonate, and finally boil it with water at high pressure for about 30 minutes to further dredge the micropores in the charcoal.

4. Take out the activated charcoal to dry, and bake it before use to achieve the best effect. The adsorption capacity of activated carbon prepared by this method far exceeds that of charcoal. Used activated carbon can also be regenerated using this method.

There are many places where you can buy activated carbon, physical hardware stores, a treasure are sold, generally buy activated carbon is to remove formaldehyde and other harmful substances, because the release of formaldehyde is very long, the release of new houses is relatively large, the use of activated formaldehyde is prone to formaldehyde exceedance, so what method should we use, recommend several easy methods to everyone.

1. Opening the window for ventilation is the best way to remove free formaldehyde, when the window is opened, there will be a steady stream of fresh air to dilute the indoor air containing formaldehyde to achieve the purpose of purifying formaldehyde, but the window is easily affected by the weather, and the effect is also affected by the house type.

2. Choose plants that can adsorb formaldehyde, pothos, aloe vera, spider plant and other plants can adsorb a certain amount of formaldehyde pollution, and can indeed remove formaldehyde. Placing some greenery in your new home can also help to beautify the room and freshen the air. However, the adsorption capacity of plants is relatively limited, and if the formaldehyde concentration is too high, the plants will wilt and die.

3. 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 formaldehyde gas can volatilize in large quantities, 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

<>5. Use an air purifier to remove formaldehyde, which is a popular method in recent years, but now there are many brands on the market, and it is recommended to choose products marked with the function of "removing formaldehyde", you must be cautious when choosing, it is not recommended to choose below 1500, and the formaldehyde filter element needs to be replaced regularly when you use it!

6. 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, in the case of outdoor wind allowing, 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.

Activated carbon is a type of charcoal that has been specially treated. Organic materials such as wood are heated in isolation from the air and react with gases to create numerous fine pores on the surface of the activated carbon. Activated carbon is usually powdered or granular, the carbon content of activated carbon is increased with the increase of activation temperature, the higher the activation temperature, the more complete the volatile substances, the greater the adsorption activity.

Adsorption mechanism: Activated carbon adsorption refers to the adsorption of one or more substances in water by using the solid surface of activated carbon to achieve the purpose of purifying water quality. The adsorption capacity of activated carbon is related to the pore size and structure of activated carbon. In general, the smaller the particles, the faster the pore diffusion rate, and the stronger the adsorption capacity of activated carbon.

Adsorption capacity and adsorption speed are the main indicators to measure the adsorption process. The size of the adsorption capacity is measured by the adsorption capacity, and the adsorption rate refers to the amount adsorbed by the adsorbent per unit weight per unit time. In water treatment, the adsorption rate determines the contact time of the adsorbent with the effluent.

Activated carbon is a specially treated charcoal that heats organic raw materials (husks, coal, wood, etc.) in an airtight environment to reduce non-carbon components (this process is called carbonization), and then reacts with gases to erode the surface to produce a microporous structure (this process is called activation). Because the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is punctate erosion, so the surface of the activated carbon has countless fine pores.

It is usually a porous amorphous carbon in powder or granular form with strong adsorption capacity. It is obtained by the carbonaceous substances (such as coal, wood, hard husks, kernels, resins, etc.) under the condition of isolated air by 600 900 high temperature, and then under the condition of 400 900 with air, carbon dioxide, water vapor or a mixture of the three of the three after oxidation activation.

Carbonization volatilizes substances other than carbon, and oxidative activation can further remove residual volatile substances, generate new and expand the original pores, improve the micropore structure, and increase activity. Low-temperature (400) activated carbon is called L-carbon, and high-temperature (900) activated carbon is called H-carbon. H-charcoal must be cooled in an inert atmosphere, otherwise it will transform into L-charcoal.

The adsorption performance of activated carbon is related to the chemical properties and concentration of the gas during oxidation activation, the activation temperature, the degree of activation, the composition and content of inorganic substances in the activated carbon, etc., which mainly depend on the properties and temperature of the activated gas.

Newly bought cars will inevitably have a smell, some car owners will simply attribute this smell to "leather smell", thinking that the smell is scattered, or get used to it, in fact, the smell of the new car is one thing, mainly the formaldehyde problem of the new car. The floor mats, seats, interiors, adhesives, etc. of new cars will release formaldehyde, which will lead to excessive formaldehyde in a small space in the car.

Tips for removing formaldehyde and odor in new cars:

1. Ventilation. As with a new house, the main thing is to do a good job of ventilation.

2. Activated carbon, leaf wide mud. These two types of materials are small in size and are very suitable for placing in the car to absorb odors and remove formaldehyde. The adsorption capacity of Ye Guangni will be stronger, and there is no need to replace it regularly.

3. Photophyllin. This is a plant extract spray, which can greatly and effectively decompose formaldehyde, and at the same time, the taste is very natural, which can remove odors.

4. Car purifier. Do your homework when choosing and buy an effective car purifier.
