Seven misunderstandings in decoration

Myth 1: It is misleading to say that the house will be peaceful in two or three months after renovation.

It is deceptive and misleading to say that it will be fine in three months. Ventilation and air drying for two or three months only temporarily volatilizes harmful gases on the surface of decoration materials, and the formaldehyde volatilization cycle is as long as 3- 15 years, while the deep volatilization of decoration materials is still slowly released. Sustained release is easy to be ignored because of its light smell, especially when the indoor temperature exceeds 29 degrees, its volatility is greater and its harm is more serious. Indoor environmental monitoring center and health medical center remind the general public: for the safety and health of you and your family, please treat them in time.

Myth 2: Is it safe to decorate a room with little or no odor?

Many people think that the indoor air is good and there are no toxic and harmful substances such as formaldehyde and benzene after living in their rooms or office decoration. Don't you know that the toxic substances in modern decoration materials are very hidden? These toxic gases are colorless, invisible and even odorless. Many people have lived in the decoration for many years without paying attention to them, which is equivalent to living in a "gas chamber" for a long time. The incubation period of decoration pollution such as formaldehyde and xylene is very long. After 5 to 10 years, many diseases are gradually exposed, which can lead to dizziness, nausea, fatigue, insomnia, memory loss, neurasthenia and serious illness. Especially children and pregnant women are the biggest victims of family decoration pollution.

Sometimes the smell of the room after decoration is not strong, for several reasons. First, the amount of harmful gases released in winter is correspondingly low; Second, due to the stimulation of the respiratory system in winter, people's olfactory organs are relatively slow. In addition, some indoor harmful gases, such as radon, are tasteless. Some people feel some peculiar smell as soon as they enter the room, but they can't smell it after a long time. Actually, it wasn't the smell that disappeared, but our noses deceived us. It is best to speak according to the authoritative test results, sometimes the harm of long-term low concentration is greater than the harm of irritating strong smell!

Myth 3: "Hot weather is most suitable for decoration" has no scientific basis.

The view that "hot weather is suitable for decoration" is an unscientific concept concocted. Of course, in hot weather, the decoration is well ventilated, drying is fast, the deformation of poor quality plates is small, and those dazzling nose smells evaporate quickly. In fact, the volatilization period of formaldehyde, benzene, xylene, etc. As long as 3- 15 years, the harmful gas on the surface layer only volatilizes temporarily during decoration in hot weather. There is no smell of dazzling and choking for the time being, which does not mean that there is no emission of formaldehyde and benzene, and the deep volatilization of decoration materials is still slowly released.

Myth 4: A decorated house can remove formaldehyde and benzene by planting plants.

Many consumers think that putting some plants indoors can remove harmful gases such as formaldehyde. In fact, the role of plants in removing harmful gases is very limited, and at best, they can only be used as an auxiliary means of indoor environmental governance. More specifically, only when the indoor air is slightly polluted can plants play a small role in removing odor. When indoor air pollution is serious, plants will be powerless, and even plants themselves will be smoked to death by harmful gases; What's more, even if plants are absorbing harmful gases, aren't people also absorbing harmful gases? In addition, plants and flowers complete metabolism through photosynthesis. During the day, some plants and flowers will remove some formaldehyde and benzene under photosynthesis, but at night, without sunlight, plants and flowers can't carry out photosynthesis, let alone remove toxic and harmful substances such as formaldehyde and benzene.

Myth 5: Are environmental protection materials polluted?

"Environmental protection materials are pollution-free" is actually pollution. The so-called environmental protection materials refer to formaldehyde, benzene, xylene and so on. Have reached the standard of unit area. Volatiles such as formaldehyde exist not only in various decorative boards and furniture, but also in various paints, adhesives and organic solvents, so the so-called environmental protection materials are still polluted. How many decoration materials does a house add up to? Although less environmental substances such as formaldehyde and benzene are released per unit area, they are piled up. Do you think it can be small? It must have exceeded the standard. Besides, people don't know whether the harmful substances exceed the standard after decoration, because he doesn't understand and no one spends money on testing.

Myth 6: Use air freshener or pineapple peel and orange peel to purify indoor harmful gases.

It is unscientific to use air freshener or pineapple peel to eliminate indoor harmful gases, which only plays a role of covering. Even if tea can absorb little harmful gas, it only absorbs air pollution. If the source problem is not solved, the effect will certainly not be good.

Myth 7: It is normal for newly bought furniture to smell.

Choose furniture scientifically after decoration: don't buy furniture with strong pungent smell; The price is relatively low, especially easy to bargain. Don't buy it; It is not produced by a regular manufacturer, or there is no factory inspection. Don't buy without a certificate. Of course, from March 2004 1, the furniture sold must be marked with formaldehyde emission, and consumers should pay more attention to asking for it. At the same time, it is best to carry out comprehensive pollution control on newly bought furniture, and pay attention to the treatment that needs long-term non-rebound. Some treatments simply do not sign a "treatment agreement." How to ensure the therapeutic effect?

Recognition knowledge of household activated carbon

1, a look at the ingredients: if it is granular coconut shell activated carbon with a size of 0.42-0.85mm, it will be good. It has been clearly stipulated in two national standards GB50325 and GB/T 18883 on indoor air quality. Example: China people * * and the national standard GB/T 18883-2002, Appendix B3. 1, stipulate that the detection method of benzene in indoor air is tube sampling, that is, the benzene in indoor air is sampled and brought back to the laboratory for analysis, and the specification standard of benzene sampling tube clearly stipulates that it should be used: "Original coconut shell activated carbon: 20-. Then take it back to the laboratory, and desorb the benzene adsorbed in the activated carbon of coconut shell with carbon disulfide for laboratory analysis. Please note that the standard clearly stipulates that it is coconut shell activated carbon. At present, many domestic manufacturers use coal-based carbon to replace or mix coconut shell carbon for household air purification, mainly due to the high cost of coconut shell carbon, but the quality is greatly reduced.

2. Second, look at the particle size: the particle size should not exceed 1.5mm: the national standard stipulates that the particle size of activated carbon is 20-40 meshes, that is to say, the particle size is about 0.42-0.85mm, and those activated carbons with a particle size above 1.5mm are not as small as the particle size. Generally speaking, the smaller the particles, the larger the specific surface area, the more developed the pore structure and the better the adsorption effect. In other words, the larger the volume of activated carbon with the same weight, the better the effect. But not too much dust.

3. Third, look at dust: that is, the post-treatment of activated carbon. The first principle of using activated carbon is that it cannot produce secondary pollution, so the production of activated carbon must be post-treated, that is, dust removal. Otherwise, its cleanliness is very poor. If you hold it in your hand, you can immediately feel a lot of dust on your hand, which will also pollute the surrounding items when you use it, and may also increase the dust content in the indoor air. At present, in order to reduce the cost, the inferior activated carbon on the market is not treated at all, and it can be identified at a glance by this method.

4. Look at the enterprise: it must be a professional manufacturer of activated carbon. When buying activated carbon, you must see where the manufacturer of activated carbon is. Only the activated carbon produced by professional manufacturers can pass the quality inspection, and it is produced by direct manufacturers. The cost is not too high, and the cost performance is good.

5, five look at packaging: professional household activated carbon production will be divided into many small carbon packages, 30 grams-100 grams/package is more appropriate. This can increase the effective contact area between activated carbon and air, that is, increase the use efficiency of activated carbon, which can be directly placed in several pollution sources.

Excessive packaging wastes raw materials and the purification effect is not ideal. In addition, the characteristic of activated carbon is that it will start to play a role once it comes into contact with air. Therefore, the regular activated carbon packaging must be sealed. If packed in cartons, there must be a heat shrinkable film on the outside of the cartons.

6. Look at the test report: the general public cannot directly identify the material of activated carbon, but they can look at the product test report and its adsorption rate for harmful gases such as formaldehyde, benzene and ammonia. Domestic formal activated carbon production enterprises need to pass at least the product inspection report issued by the inspection agency at or above the municipal level before they are eligible to enter the market.

I suggest you use Haozeng original ecological activated carbon, which is pure coconut shell original ecological activated carbon; Factory direct sales, absolutely cheap, can be used.
