The miscellaneous army of indoor air testing and management industry

Many consumers have a lot of misunderstandings about the knowledge of indoor air pollution, and think that putting some plants in the room can remove harmful gases such as formaldehyde is a typical one. In fact, the effect of plants in removing harmful gases is very limited, and at best it can only be used as an auxiliary means of indoor environmental treatment. To put it more explicitly, only when the indoor air is mildly polluted, can plants play a small role in removing odors.

When indoor air pollution is severe, plants are powerless, and even the plants themselves are fumigated to death by harmful gases;

In addition, formaldehyde is only synonymous with harmful gases that endanger human health indoors, in fact, there are many harmful gases that pose a serious threat to human health. With the progress of science and technology and the improvement of national standards, decoration material manufacturers and furniture manufacturers have made fruitful efforts, and the formaldehyde index has been relatively controlled, so most of the compliant decoration materials are used. The national "Indoor Air Quality Standard" GB T18883 2002 clearly stipulates that in addition to formaldehyde, several harmful gases that are most harmful to human health include benzene (benzene, toluene, xylene), ammonia, TVOC, etc.;

The scientific method is that after the house is renovated, indoor air testing should be carried out to determine the actual situation of indoor air pollution. Then ventilate more.

There is an effect.

1. It is necessary to find a professional testing agency to conduct testing, to confirm the cause of pollution and the degree of pollution, and after DAO confirms the degree of indoor air pollution, consumers can consult with a treatment company for harmful gases to determine a reasonable treatment plan.

2. At present, there are two methods of indoor air pollution control, which are reagent treatment and air purifier technology, which are studied from the aspects of treatment objects and treatment effects. Reagent treatment technology is mainly substances that can react with formaldehyde, ammonia, benzene, and TVOC or substances that can react with them; Air purifier technology mainly refers to photocatalytic technology, which catalyzes the decomposition of harmful substances through photocatalysts, which are semiconductor materials. The more popular treatment products in the market are activated carbon and air purifiers.

Some of the indoor air detection and treatment are effective and some are not easy to say, it is not very clear which ones are good, but you can suggest back how to treat the air yourself, the method is as follows:

1. Usually open the windows for ventilation at home to ensure air flow, and do not open the windows.

2. You can also put some coffee bean boxes and tea leaves to taste.

3. Use some leaves and mud to fully adsorb harmful substances.

Find a regular test with.

Copying the management company to carry out attack detection and governance must be effective, I am Lianyungang du, Xinju zhi

After the renovation is completed for one month, the formaldehyde removal DAO is carried out

Decoration pollution is mainly caused by the gas pollution caused by the materials and indoor furniture used in the decoration process, mainly including: formaldehyde, benzene, toluene, xylene, TVOC, ammonia and other harmful gases. There are many indoor environmental pollutions, a considerable part of which is caused by improper materials used in the decoration process, including formaldehyde, benzene, xylene and other volatile organic compound gases.

Governance misunderstandings. Myth: 1. Vinegar fumigation.

Some consumers have tried fumigation vinegar to remove the odor after home renovation. Experts pointed out that vinegar is an acidic substance, which has the effect of weakly neutralizing ammonia in the air, but will not react with other harmful components such as formaldehyde.

Myth 2: Placing pineapples.

Some people think that putting a few pineapples in each room can eliminate the smell of paint, and more in larger rooms. Pineapple will volatilize the aroma and play a certain role in covering the odor, but it does not decompose and remove harmful substances; The senses can no longer smell the unpleasant smell, but the harmful gases are still there.

Myth 3: Rely too much on plants.

Some ornamental plants can indeed absorb certain toxic gases, such as plants that can absorb formaldehyde include cactus, spider plant, aloe vera, ivy, iron tree, chrysanthemum, etc.; The three kinds of flowers, such as ivy, iron tree and chrysanthemum, have the ability to absorb benzene and reduce benzene pollution. But the key is that their role is quite limited, in the face of the intensive emission of harmful gases at the end of the renovation, their weak absorption effect, not only can not remove the pollution to save the Lord, and even their own health is difficult to protect. A consumer has reflected:

The flowers in my old house turned yellow a few days after they were placed in the new house. Experts say this is likely to be caused by indoor pollution.

Myth 4: Place tea roots.

Some people even place dried tea roots after brewing tea in their wardrobes and rooms, hoping to help remove the poison gas. As everyone knows, the effect of tea root in this regard is like dry leaves and toilet paper, with almost no absorption and decomposition.

Myth 5: Ozone generators.

Using an "ozone generator" as an air purifier is an even bigger misunderstanding. Although ozone has the effect of sterilization and disinfection, it is also a medical conclusion that it is harmful to the human body. The use of ozone disinfection can only be carried out in an environment where the human body is not in contact, and it is obviously not suitable for use as a room air purification.

As for the use of ultraviolet emission sources as indoor disinfection equipment, foreign countries have long been eliminated, and Hong Kong and other places in China have also been eliminated as early as 20 years ago.

The above is answered by Beijing Dayuan Environmental Testing Technology Research Center.

Commonly used indoor air pollution control schemes.

When the formaldehyde or TVOC concentration in the indoor air exceeds the standard, please open the doors and windows immediately to maintain the circulation of indoor air, which can immediately reduce the formaldehyde or TVOC content in the indoor air, maintain air circulation, and reduce the harm to the human body.

Activated carbon adsorption method.

Activated charcoal is an internationally recognized drug addict, activated carbon masks, and gas masks all use activated carbon. Placing activated carbon indoors can adsorb indoor pollutant gases to a certain extent and achieve the effect of air purification. Results can be seen in about 7 days.

Catalytic oxygen method.

It mainly includes nano photocatalytic technology, negative oxygen ion technology, etc., which are mainly used in air purifiers and formaldehyde scavengers. Results can be seen in 48 hours.

Plant deodorization.

General indoor environmental pollution in light and moderate pollution, pollution value in the national standard 3 times below the environment, the use of plant purification, can achieve a better effect, according to the different functions of the room, the size of the area of the selection and placement of plants, in general, about 10 square meters of the room, meters high plant put two pots more suitable.

Plants that have the effect of absorbing benzene, such as ivy, iron tree, etc.

Plants that have the effect of absorbing trichloroethylene, such as evergreen, zouju, agave, etc.

Plants that have the effect of absorbing sulfur dioxide, such as moon season, rose lamp.

Plants that have a vacuuming effect, such as osmanthus.

Plants with bactericidal properties, such as mint.

Want to test the air?

There are a lot of testing companies.

What is it about, landlord? The landlord didn't ask the question clearly!

The detection method of the general governance company If the six-in-one device is used, there are some deviations in the data.

However, it can reflect the quality of the indoor environment;

If you are looking for a professional organization to do the test, the cost is about 500 points (relatively cheap).

There are many ways to clean up air.

1) Pharmacy. photocatalysts; oxidants, etc. Agents that are specialized in removing certain pollutants, such as formaldehyde and ammonia and benzene.

2) Equipment. There are many brands and manufacturers of air purifiers.

3) Film. One way to do this is to apply a film to the surface of the source of contamination.

4) Grow plants.

5) Put activated carbon, ventilation, etc.

Analysis, if the landlord does not detect the management company, he will open the windows in the room for ventilation for a long time, which can greatly reduce the amount of pollutants. Buy an air purifier in a room of key concern, and recommend Yadu's (the first of the top ten brands in the country).

Plant and activated carbon removals are limited and limited to the bottom amount.

The treatment of photocatalysts and other agents will play a certain role, and the effect will be obvious. However, long-term research is required.

The landlord can also use the combination of photocatalyst treatment and air purifier to reduce the harm of indoor air!

Most of the indoor air monitoring is qualitative monitoring, and I don't know what the governance is talking about.
