In the face of decoration pollution control, is activated carbon reliable or negative ions more effe

In terms of decoration pollution control, activated carbon and negative ions have their own advantages, but in general, the effect of activated carbon is more significant. Activated carbon has a strong adsorption capacity, can effectively adsorb formaldehyde, benzene and other harmful substances produced in the decoration, and is relatively close to the people, the market price is generally between 100-500 yuan kg, depending on the quality of activated carbon and the quantity purchased.

The cost of using activated carbon mainly includes the purchase cost and replacement cost. The purchase cost will vary depending on the type and quality of activated carbon**. Generally speaking, the ** of wood activated carbon will be slightly higher than that of bamboo activated carbon, because the adsorption capacity of wood activated carbon is stronger.

The replacement cost is mainly because the adsorption capacity of activated carbon will gradually weaken after a period of use, and it needs to be replaced regularly, and it is generally recommended to replace it every 3-6 months.

Negative ions improve indoor air quality by releasing negative ions, which has a certain effect on removing smoke and dust, odors, etc., but the removal effect on harmful substances such as formaldehyde and benzene is relatively weak. The ** of negative ion products generally ranges from a few hundred to several thousand yuan, depending on the brand and performance of the product.

The cost of using anion products mainly includes purchase costs and maintenance costs. The cost of purchase mainly depends on the brand and performance of the product, and generally speaking, products with well-known brands and good performance** will be relatively high. The maintenance cost is mainly electricity, because the negative ion product needs to be driven by power supply, so a certain amount of electricity will be generated during use.

In general, activated carbon and negative ions have their own advantages, but in terms of decoration pollution control, the effect of activated carbon is more significant, and it is more close to the people.

Here, experts remind that the adsorption capacity of activated carbon originates from the pore structure in the carbon structure, but incorrect use will seriously affect the purification effect of activated carbon. Usually activated carbon can only play an adsorption function when placed in a relatively closed drawer, wardrobe and other small spaces, and if it is placed in the air of air flow, its purification and adsorption effect will be greatly weakened.

This is mainly due to the fact that the structure of the orifice is two-way circulation, and the amount of pollutants inhaled and released is basically the same when the air flow is strong.

The purification rate of formaldehyde with high concentration and small particle size anion is as high as 99%.

The purification rate of formaldehyde with high concentration of small particle size anion is as high as 99%, and its purification effect kills activated carbon.

Small particle size anion is a negatively charged oxygen ion that carries excess electrons, and has the characteristics of small particle size, high activity, and long migration distance. In the "Environmental Health and Negative Oxygen Ions" edited by Lin Jinming, an academician of the Chinese Academy of Sciences and a professor at Tsinghua University, the purification function of small particle size anion is attributed to the fact that the excess electrons carried by small particle size anion degrade toxic substances into non-toxic or less toxic substances by breaking the chemical bonds that play a stabilizing role between toxic substances.

The latest research by Japanese authorities has found that negative ions can degrade formaldehyde into water and carbon dioxide, and the current application of ecological anion generation chip technology in negative ion equipment has made the concentration of small particle size anion released by some negative ion equipment reach the maximum value. Tested by the Chinese Center for Disease Control and Prevention:

The efficiency of formaldehyde purification by negative ion equipment using this technology is as high as 99%.

The activated carbon of the air purifier is of little use for the problem of formaldehyde pollution in the room.

Activated carbon is made of carbon-containing substances (coal, wood, hard husks, etc.) as raw materials, which are converted by pyrolysis at high temperature and certain pressure, and form a complex pore structure and huge surface area during reactivation process, so that it has good adsorption capacity and chemical stability.

Activated carbon does not have much scavenging effect on formaldehyde in indoor air, and other physical adsorption products also have this problem.

In the decoration of new houses, formaldehyde is mainly present in plate furniture, paint surface, fabric sofas, etc. The action of activated carbon and negative ions is not very obvious and cannot decompose formaldehyde. Formaldehyde is a harmful substance, adsorbed by plants, charcoal bags, and can also be ventilated, all of which have a certain effect.

Activated carbon has a certain effect, and it needs to be used for a period of time and then sunned, and there will be secondary pollution.

Formaldehyde release is slow and lasts for up to 3 to 15 years, The public's method of removing formaldehyde is ventilation, raising some plants or some roles, you can raise some spider plants, aloe vera, cactus, tiger tail orchid and other flowers to absorb indoor polluting gases, if you are not at ease, use some formaldehyde removal materials, like Ye Guang mud materials, the role of formaldehyde adsorption, Ye Guang mud because of its own space three-dimensional network structure and double helix nano winding structure can adsorb, lock and decompose formaldehyde, will be better than activated carbon, The range of applications is also wider.

Activated carbon: It is mainly used to adsorb harmful gases, filter out insolubility, and adsorb some solubility. Characteristics of adsorption of harmful substancesActivated carbon is the principle of physical adsorption, which relies on air as a medium in the process of action, so it is defined as a passive air purification material.

Negative ions: dust removal and sterilization are more effective in reducing the harm of secondhand smoke. It can effectively remove and neutralize formaldehyde, benzene, toluene, ammonia, carbon monoxide and other toxic gases, in order to protect human health.

Clean air, smoke and dust removal: Negatively charged negative ions are electrode-neutralized with positively charged smoke and dust floating in the air to cause them to be naturally deposited.

Both of these are effective in removing formaldehyde, and the function of negative ions is more than that of activated carbon. You can choose one or the other.

What is the good thing about negative ion control decoration pollution?

Common decoration pollutants mainly include fine dust and other particulate matter, biological pollutants such as insect mites and bacteria, and chemical pollutants such as formaldehyde. For the particulate matter suspended in the air that can enter the lungs, the negative charge carried by the negative ions can neutralize the positive charge carried by it, so that the positive and negative phase of the hail can be condensed into a clump and then fall to the ground. "Environment, Health and Negative Oxygen Ions" is a book written by Professor Lin Jinming of Tsinghua University on the professional study of negative ions, which writes that negative ions carry excess electrons and have strong oxidation resistance.

Antioxidant properties enable negative ions to alter the original structure or energy transfer of biological contamination such as bacteria, causing it to die.

For the answer to the question of whether it is good to treat decoration pollution with negative ions, the principle of action of negative ions on chemical pollutants such as formaldehyde is more harmful. Japanese scholar Hirota et al. found that negative ions are an important active substance to promote their decomposition, which can promote the separation of formaldehyde oxygen chains in formaldehyde molecules. Moreover, after formaldehyde is degraded, water and carbon dioxide are produced, which will not cause "secondary pollution".

Decoration pollution will cause leukemia and other diseases has been affirmed by the public, and the negative source or ion treatment of decoration pollution has become a new problem. Understanding the mechanism of negative ions degrading volatile organic compounds such as formaldehyde, newly renovated owners can use green plants and negative ions, two treatment methods that will not cause "secondary pollution", to solve decoration pollution and relax and enjoy a healthy new home. Experts from the Chinese Air Anion and Ozone Research Society remind:

Eco-grade anions with small particle size, high activity and long migration distance have a better effect than those released by other equipment.

Any kind of indoor air pollution control method has its limitations, and activated carbon is only one of them.

But now manufacturers often mislead consumers, mainly two points are willing to share with the landlord.

First of all, the working principle of activated carbon is only through its own cavity structure for physical adsorption, so it is determined that only when the polluted air flows through the physical structure of the activated carbon, the activated carbon will convection through this part of the air inside it to produce a purification effect, and regardless of the particle size and quantity that can be purified, that is, how to purify the purification effect, how can the landlord make the air in the living room flow and pass through the inside of the activated carbon? Moreover, the pollutants and harmful gases after decoration are continuously released. The landlord has thought about this question and understood it, but the next question doesn't have to be read.

Second, the adsorption capacity of activated carbon has a lot to do with the temperature and humidity of the indoor environment, and the vast majority of activated carbon manufacturers do not give consumers any reference data in this regard. The saturation adsorption capacity of activated carbon under different temperature and humidity conditions varies greatly (i.e., the critical value of adsorption force), and the change of temperature and humidity conditions will lead to the change of the critical value, which determines that the use of activated carbon has potential safety hazards. Why some manufacturers advertise that activated carbon can be recycled after being exposed to outdoor sunlight for a period of time is to use the temperature increase to reduce the critical value of adsorption power, so that the adsorption substances are released in a concentrated manner, and at the same time, the activated carbon can regain the adsorption function.

This means that activated carbon in a saturated state has the potential to become the next and most concentrated source of pollution in your home.

In summary, activated carbon is only suitable for use in very small spaces, and attention should be paid to replacing it before adsorption is not saturated. If you expect it to effectively remove the decoration pollution in your home, please don't waste money on it.

Activated carbon for decoration pollution control can have a little imperceptible effect.

As for what big role it can play, I don't think it's really big enough.

If the decoration materials in your home are no longer polluted, ventilation is fine, if not, then activated carbon will not do anything.

Activated carbon is easily saturated, depending on whether the pollution in the place where it is placed is serious, if it is serious, it will generally fail in a day or two. Bamboo charcoal adsorbs polluted air, just like a cup, water is like polluting gas, the amount of pollution is like a large flow of water, the flow of water is large, the cup is full all of a sudden, it can no longer hold water, if the amount of pollution is small, it is like dripping water slowly into the cup, it takes a long time to drip full, but if the amount of pollution is very small, there is no need to put it, ventilation can solve the problem.

To sum up, there should be two possibilities for activated carbon for decoration pollution control:

1. It is just a blindfold method for governing the company, the purpose is to make customers feel that there are some things that can be seen, so as to collect money.

2. The governance company is very responsible, the governance is up to standard, and it wants to achieve lower requirements than the national standard until the decoration pollution is completely eliminated.

Hopefully the latter.

Activated carbon can adsorb a lot of toxic and harmful substances, such as formaldehyde, etc., and when the concentration is high, it is not possible to completely solve the problem by relying on activated carbon adsorption, or please ask a professional decoration pollution control company to solve it, such as Yancheng Shengyuan decoration pollution control.

After decoration, the interior will contain more harmful gases, such as formaldehyde, benzene, ammonia, TVOC, etc.

It is to use instruments or other methods to detect the air in the room.

Activated carbon is to adsorb harmful gases in the room, so as to play a role in controlling indoor pollution.

At present, there are many products on the market to remove formaldehyde, such as activated carbon, photocatalyst, bamboo charcoal, air catalyst, etc.

Activated carbon is also a product that purifies the air. It is used a lot in the case of less pollution. When choosing activated carbon, there are some requirements to pay attention to.

The adsorption effect of bamboo charcoal is not good, and it will be saturated, and the activated carbon is okay. Activated carbon is a black powdery or granular amorphous carbon, which is irregularly arranged in structure due to the microcrystalline carbon, and there are fine pores between the cross-connections, which adsorbs harmful gases such as formaldehyde and benzene. Proper heating of the adsorbed solution can increase the adsorption rate of pigment, strengthen the adsorption effect, and accelerate the removal effect of pigment due to the high temperature is conducive to intermolecular Brownian motion.

Activated carbon can remove formaldehyde, the effect is very good, like Qingyi activated carbon made of coconut shell is very good, can effectively remove formaldehyde and other harmful gases.

Activated carbon can really effectively remove formaldehyde pollution after decoration, but it is not durable, it is easier to saturate, and it needs to be exposed and replaced, so you can consider some other ways to remove it

1. First of all, it needs a lot of ventilation, which will help the flavor to disperse faster.

2. Then you can consider using some Yeguang mud to replace activated carbon, Yeguang mud is different from activated carbon, not easy to saturate, can be adsorbed and decomposed of formaldehyde for a long time, and the effect is still good.

3. Vinegar: Hit a small bucket of water, add some vinegar, put it in the room, try it a few times, and the smell will gradually disappear. The reason is that water can adsorb formaldehyde, and vinegar can play a role in stabilizing formaldehyde.
