How to get rid of odors in home improvement Does activated charcoal work?

Home decoration to remove odor with activated carbon, the effect is there, but not particularly obvious, and troublesome.

Activated carbon is a physical action to adsorb formaldehyde and other odors, when the adsorption is fully loaded, it can no longer adsorb odors, and must be put in the sun before it can be reused. In a newly renovated house, it is necessary to dry it about once a week or so. If you want to use activated carbon to remove odors for a long time, you can use activated carbon to make handicrafts --- carbon treasures at home, which can not only remove odors, but also be used as decorations to beautify the room.

The most effective way to remove odors in home decoration is to open windows for ventilation, open cabinet doors, etc., and try to let the wind blow. If the smell is strong and strong, simply put the cabinet, bed, etc., do not lean against the wall or the ground, and try to leave space to ensure that there are no dead corners when the wind blows, or use an electric fan to blow the dead corners.

The method of home decoration to remove odor can also use plants, such as spider plants, cactus, etc., and you can also use Nawei cards in closed spaces, which will have a certain effect.

After decoration, you can make a basin of water, add an appropriate amount of vinegar and put it in a ventilated room, and open the furniture door; Buy some pineapples and put a few in each room, and put more in the larger room. Pineapple is a coarse fiber fruit that absorbs the smell of paint. To quickly remove any remaining paint smell, you can also use a cotton ball soaked in citric acid and hang it in the interior and wood furniture for a few days to see the results.

If you find these methods cumbersome, you can go to the market and pick up some high-tech deodorant cleaners, which can remove harmful gases emitted by newly renovated houses, new furniture, etc. In newly renovated rooms, this odour-removing detergent can be poured into a plate and placed in each room separately to effectively remove unpleasant odors after a few days in a row. The most economical way to do this is to have a few pots of suitable flowers and plants at home.

According to reports, the flowers and plants that can remove odors are: Monstera bamboo, also known as monstera, Penglai banana, evergreen vine. Monstera has a strong carbon dioxide absorption characteristic at night.

Canna is also known as safflower banana and anchovy. It has strong absorption properties for sulfur dioxide. Pomegranates Placing one or two pots of pomegranates indoors can reduce the amount of lead in the air.

Haitong is also known as Baozhu incense and Qili incense, which can absorb photochemical smoke and can also prevent dust and sound insulation. These two kinds of flowers can absorb more harmful gases such as hydrogen sulfide, hydrogen fluoride, phenol, and ether. Chrysanthemums, iron trees, and growing vines These three flowers have the ability to absorb benzene and can reduce benzene pollution.

Spider plant and aloe vera These two flowers can eliminate formaldehyde pollution and purify the air.

Carbon on formaldehyde mainly plays an adsorption role, very passive, if you choose to buy carbon, you have to take it out at any time to dry and replace, and the volatilization period of formaldehyde is 3-15 years, so the cost is very high, if you want to fundamentally remove formaldehyde, I suggest that you buy potion collection ventilation, now there are many formaldehyde removal products on the market, I suggest more comparison.

Useful, if you really can't find it, use charcoal.

New cars will have some peculiar smells more or less, such as adhesives, glass films, car seats, interior panels, etc., and deodorants such as multi-window ventilation and carbon bags can be used.

Activated charcoal is not very suitable for home furnishings, it is better to use grapefruit peel orange peel will be better.

The best thing to do is to ventilate naturally for a long time before you can live in it.

Activated carbon is made of carbon-based substances as raw materials, containing a large number of micropores, which can adsorb organic pollutants and some inorganic substances, and its adsorption capacity depends on its own pore size distribution and the molecular size of the adsorbed substance. Because activated carbon has adsorption function, many businesses claim that activated carbon has the function of removing formaldehyde and indoor odor.

However, the China Consumers Association commissioned a professional testing agency to test some activated carbon products, and the test results showed that some activated carbon detection indicators were low, and some were even inferior to ordinary hot pot charcoal. Among the 16 samples, only 5 samples were nominally air purifying, and the detection index value was high. The remaining 11 samples were nominally air purifying, but all of them had low detection index values or low individual index values.

1. Remember to expose activated carbon to the sun after 48 hours.

Many people buy activated carbon, and they are used to putting the product directly indoors or in the car. Experts remind, "Because the activated carbon is placed in one place for a long time, the adsorption capacity will reach saturation, and then the absorbed formaldehyde or other harmful substances will be released again, causing secondary pollution." ”

Song Hongbo suggested that before use, it is best to expose the activated carbon to an outdoor ventilated place for a period of time. It is about 48 hours of use, and it is best to take it to an outdoor ventilated place to dry. Activated carbon that has adsorbed formaldehyde can be reused after being exposed to the sun or dried outdoors.

2. Try to buy activated carbon packaged in plastic bags.

When purchasing activated carbon, you should try to buy brand products with a certain reputation, and at the same time pay attention to check the product label, carefully check whether the product name, net content, manufacturer's name, address, production date, shelf life and other contents are standardized, so as to avoid buying three-no products.

Not only formaldehyde, activated carbon has a good adsorption effect on other gases and moisture in the air. Therefore, when purchasing, try to choose activated carbon with a plastic bag sealed packaging on the outside, rather than products packaged in bulk or non-woven fabrics.

3. The performance of coconut shell activated carbon is good.

From the point of view of appearance, a high-quality activated carbon product should be a black powder or granule with a loose structure. If it's the kind that is cemented or compressed into charcoal cakes, try not to buy it.

You can also smell it when you buy it, good activated carbon smells no peculiar smell, and products containing odors such as air fresheners may itself cause secondary pollution.

Generally, the surface area of activated carbon used in water treatment is not necessarily too large, but it should have more transitional pores and a larger average pore size. Some liquid-phase activated carbons available in the Japanese market have the following characteristics: a specific surface area of 850 to 1000 m2 g, a pore volume of to, and an average pore radius of 40 to 50 a.

Activated carbon is a specially treated charcoal that heats organic raw materials (husks, coal, wood, etc.) in an airtight condition to reduce non-carbon components, and then reacts with gases, and the surface is eroded, resulting in a microporous structure. So can activated charcoal remove odors?

1. Activated carbon can remove odors, and the effect of activated carbon in removing odors is not small.

2. Activated carbon is made of carbon-based materials. It contains a large number of micropores that can adsorb organic pollutants and certain inorganic substances. Its ability to adsorb a substance depends on its pore size distribution and the molecular size of the adsorbed substance.

Since activated carbon has an adsorption function, many businesses claim that activated carbon has functions such as removing formaldehyde and indoor odors.

3. However, the China Consumers Association has commissioned a professional testing agency to test some activated carbon products. The test results show that some activated charcoal has low detection index values, and some are even inferior to ordinary hot pot charcoal. Of the 16 samples, only 5 had the nominal air purification effect and had higher detection index values. The remaining 11 samples had nominal air purification effect, but all of them had low detection index values or low individual index values.

Through the above, it can be known that activated carbon can remove odors, and can also be used to purify gases and some magazines, and the adsorption effect is also very good, and there will be a surprise when used.

After the decoration of the house, there must be a peculiar smell, at this time we need to prepare some methods to remove the smell, such as the most common is to open the window for ventilation and plant absorption, these are the methods that people use more, have you heard of activated carbon to taste? SoDecoration deodorization activated carbonHow does it work? What are the key points of using deodorizing activated carbon for decoration?

Let's introduce it to you.

First, the principle of deodorization activated carbon for decoration.

1.Activated carbon is a very fine carbon particle with a large surface area, and there are even finer pores --- capillaries in the carbon particle. This Wu Shou Song capillary has a strong adsorption capacity, because the surface cavity of the carbon particles is very large, so it can be in full contact with the gas (impurities), when these gases (impurities) touch the capillary will be adsorbed, play a purification role.

2.Air-purifying activated carbon is an internationally recognized highly efficient adsorption material, which was used in gas masks as early as the "First World War". Activated carbon is widely used to purify the air in automobiles and chambers.

Activated carbon is a porous carbon-containing substance, and its developed pore structure makes it have a large surface area, so it is easy to fully contact with toxic and harmful gases in the air, and the strong adsorption force field around the activated carbon pores will immediately suck toxic gas molecules into the pores, so activated carbon has a strong adsorption capacity.

Second, the use of deodorization activated carbon for decoration.

1. Activated carbon packaging is best sealed packaging. Because the air is more or less permeated with a variety of organic macromolecular substances, especially in the newly renovated store or home storage cabinet in the phenolic concentration is very large, these substances will be adsorbed by activated carbon, over time, the adsorption performance of activated carbon will be reduced or even unusable because of the adsorption of these substances. Therefore, the higher the adsorption value of activated carbon, the more it should be sealed to prevent the performance of activated carbon from being interfered with by the outside world.

2. Some of the counterfeit activated carbon on the market is passed off as a semi-finished product of activated carbon, and the carbonized material can only become real activated carbon after the "activation" process, and the activation process is the most important process of manufacturing pore structure in the activated carbon manufacturing process. The carbonized material lacking this process can be said to have almost no adsorption performance, which makes consumers suffer a lot. Because the carbonized material does not have the process of activating and forming pores, the surface is smoother than the activated carbon, and the color is whitish, slightly metallic, the feel is harder than the activated carbon, and the weight is much heavier.

A good way to remove odor is the removal method of activated carbon, which is now very high, so what are the principles and key points of use of decoration deodorization activated carbon, through the above introduction, I think everyone understands these too.
