In what furniture benzene is in and what are the characteristics

Mainly because of harmful substances such as formaldehyde and benzene emitted from furniture paints and glues, this kind of smell is often not good for human health. Today, I will share with you the method of removing formaldehyde and odor from furniture, I hope it will help you.

1. This is a gift from nature to us, and it is the most economical way to remove aldehyde, as long as the window is opened, fresh air will enter the room, and formaldehyde will be purified by dilution.

<>3. The use of activated carbon is also a good choice. The surface of activated carbon is rich in pores, which can adsorb indoor odors, and also has a certain effect on pollution control, but the activated carbon treatment capacity is limited, and it will produce saturation after about half a month of use, and it is impossible to continue to work.

<>5. The air purifier has a good filtering effect on odors and indoor pollutants, and can achieve the purification effect relatively quickly, but it needs to be continuously turned on 24 hours a day, and the purification range of each machine is limited, and each room needs to be configured, so the cost of using it will be relatively high, and the cost of using the whole house is a bit high, and families with enough budget can give it a try.

6. There are many formaldehyde removal companies on the market, and the methods and technologies are also uneven, and some companies are easy to repeat after governance, which is also the reason why everyone has mixed opinions about formaldehyde removal companies, and it is recommended to hire a big brand of aldehyde removal companies, so that the later effect can be guaranteed

The general term of benzene and derivatives, benzene in a broad sense includes all aromatic compounds, and in a narrow sense, it refers to benzene ring-containing compounds that are distributed in the human production and living environment and cause harm to the human body, including BTEX.

Due to production and domestic pollution, benzene series can be widely detected in human living and living environments. And it has a strong harm to the blood, nerve and reproductive system of the human body. Developed countries have generally regarded the concentration of benzene in the atmosphere as one of the contents of routine monitoring of the atmospheric environment, and have set strict indoor and outdoor air quality standards.

All non-natural wood contains these two materials, just a little difference, mainly concentrated in the adhesive of plywood, furniture paint, and the formaldehyde content in MDF is amazing! Volatilization will last for several years (formaldehyde only begins to volatilize naturally when the room temperature reaches more than 30 degrees), and the content in wood core board is relatively small (after all, it is mainly spliced with wood). The content of benzene in wall paints is more.

Because formaldehyde is a large number of chemical raw materials used in the textile industry and building decoration, wardrobes and desks may contain formaldehyde.

There is also no possibility of "zero formaldehyde" furniture on the market.

Even if each piece of furniture and every building material is environmentally friendly, too much of it is used in a house, which may cause the overall indoor pollution to exceed the standard, and the furniture combination will produce "superimposed pollution".

Inferior furniture is likely to contain formaldehyde and benzene, because the boards used are generally large formaldehyde releases, and it is easy to exceed formaldehyde when ventilation is not smooth.

1. The most common way to remove formaldehyde indoors is to open windows for ventilation, and this method has almost no cost. But the ventilation method also has disadvantages, first of all, the location of the house should be good to achieve the effect of ventilation, and secondly, the formaldehyde in the decoration materials is in a state of continuous release, and it is impossible to completely remove formaldehyde through window ventilation, it can only play an auxiliary role in removing formaldehyde.

2. Putting some green plants at home can also effectively remove odors, especially pothos, spider plants, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases. In addition, large plants such as the Ping An tree and the camphor tree, which are more popular on the market, can release a fresh gas on their own, which makes people feel happy, and is also more suitable for removing the smell of new furniture.

<>3. The use of activated carbon is also a good choice. The surface of activated carbon is rich in pores, which can adsorb indoor odors, and also has a certain effect on pollution control, but the activated carbon treatment capacity is limited, and it will produce saturation after about half a month of use, and it is impossible to continue to work.

<>5. The fresh air system can ensure that the home is in a ventilated state for 24 hours, which can greatly increase the exchange of indoor air and the outside world, although the effect is very good, but the first fresh air system is more expensive, and the installation before decoration is a better choice.

6. At present, most of the photocatalysts often mentioned are titanium dioxide, which can decompose formaldehyde into carbon dioxide and water through ultraviolet irradiation, but it needs to be involved in light and ultraviolet rays when working, and there are certain restrictions in removing formaldehyde

Most of the furniture is made of man-made panels, so adhesives will be used in processing and production, and formaldehyde exists in the adhesive, so new furniture will contain formaldehyde, benzene and other harmful substances. After we buy furniture, we can remove the formaldehyde and odor emitted by the furniture in the following ways.

1.Ventilation and aldehyde removal is a gift from nature, as long as the weather allows us to unscrupulously open the window to remove aldehyde, through the dilution method to control formaldehyde within a safe range, but the release of formaldehyde is longer, the use of ventilation to remove aldehyde requires long-term persistence, and other methods need to be taken to reduce formaldehyde concentration when ventilation is not smooth.

2.The use of green plants to purify formaldehyde is a very promising way to remove formaldehyde, plants will adsorb a part of formaldehyde during photosynthesis, but the absorption is extremely small, and it is recommended as an auxiliary method when removing formaldehyde.

3.Activated carbon is a traditional physical adsorption material, which has been well received in the treatment of indoor and outdoor pollution, its specific surface area is large, and it has a strong adsorption capacity, but its adsorption capacity is limited, and it does not have the function of decomposition.

4.Fresh air system is a kind of indoor air purification product, through the system's filtration device, the introduction of outdoor fresh air, the discharge of indoor harmful substances, so as to reduce the indoor formaldehyde concentration, but due to the continuous release of formaldehyde, fresh air needs to be turned on for a long time, and because of the air volume, noise and other reasons, it is more reliable for ordinary families to open the window.

5.At present, most of the photocatalysts that are often mentioned are titanium dioxide, which can decompose formaldehyde into carbon dioxide and water through ultraviolet irradiation, but it needs to be involved in light and ultraviolet rays when working, and there are certain restrictions in removing formaldehyde.

It will be a little difficult to use a single method when removing aldehydes, but it is recommended to use a combination of them, which will have a better effect and make aldehyde removal smoother!

The benzene we come into contact with in daily life mainly comes from indoor decoration materials, benzene and benzene series is a commonly used chemical raw material, usually used as an organic solvent for paints, coatings, and fillers, such as "Tianna water" and "thinner", and their main components are benzene, toluene or xylene. Benzene substances are highly volatile, and will be quickly released after decoration and use, causing indoor air pollution.

The various adhesives used in decoration are another major ** of "benzene". At present, solvent-based adhesives still have a certain market in the decoration industry, and most of the solvents used in them are toluene, which contains more than 30% benzene, but because of the solubility, solubility, adhesion and other reasons, it is still used by some enterprises. Some families buy sofas that emit large amounts of benzene, mainly due to the use of adhesives with high benzene content in production.

This is also the main cause of "benzene" pollution in cars.

The waterproof materials used in the decoration, especially some waterproof coatings prepared with raw powder and thinner, are tested 15 hours after construction, and the benzene content in the indoor air still exceeds the maximum concentration allowed by the state. Finally, benzene is also present in some low-grade and counterfeit paints, which is also an important reason for excessive benzene content in indoor air.

Long-term inhalation of benzene can cause aplastic anemia.

All furniture contains benzene and its family of substances, but branded furniture may be lighter. But we still have to pay enough attention. In addition to benzene, formaldehyde pollution is more prominent.

It should be toluene and xylene.

It does not exist in furniture, but in the materials used for furniture, water-based and solvent-based building decoration coatings that use benzene as chemical raw materials, various solvents, thinners, colorants, driers, resins, oils, curing agents, etc.

Usually there will be ... But it depends on what kind of paint it's painted on.

Benzene is an organic compound, long-term exposure to carcinogenic, teratogenic risk, after the decoration of the indoor odor is mostly ** formaldehyde, benzene and other harmful substances, and now there are many ways to remove formaldehyde and benzene on the Internet, such as the use of some fruit skin, water, vinegar and onions, in fact, these methods are nothing more than the use of their own taste to cover the smell of formaldehyde and benzene, there is no scientific basis at all, so these methods are circulated to treat the symptoms but not the root cause, and the following methods should be used to solve formaldehyde and peculiar smell.

1. Open the doors and windows to circulate the air naturally, and discharge harmful gases to the outside through the air flow, which is simple and effective. Try to keep the windows open for ventilation indoors for a long time, and you can also use electric fans to assist in accelerating indoor and outdoor air convection flow, forced ventilation for a month, and the decoration taste will be greatly reduced. It is best to place the newly purchased furniture at the ventilated outlet, so that the odor is directly excluded outside.

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. Activated carbon has the function of adsorbing formaldehyde and other harmful substances, but activated carbon does not have the function of decomposition, so the adsorption capacity is limited, easy to saturate, and needs to be replaced frequently, otherwise it will become a new pollution source to emit harmful substances to the outside, resulting in indoor secondary pollution.

5. Now the company in addition to formaldehyde can be seen everywhere, the industry is now very chaotic, and there is a deviation in the first and the effect of removing formaldehyde.

6. The main principle of photocatalyst is that the spray will adhere to the surface of the object to form a strong film, on the one hand, it will slow down the release of formaldehyde, on the other hand, it will contact with the film during the release process, and oxidize formaldehyde by using the photocatalytic performance of the photocatalyst. However, in daily life, the film may oxidize and wear, and the effect will be halved

Benzene (C6H6) is a hydrocarbon, the simplest aromatic hydrocarbon, which is a sweet, flammable, carcinogenic and toxic colorless transparent liquid at room temperature, with a strong aromatic odor.

Indoor benzene pollutio mainly comes from interior decoration coatings, wood paints, adhesives and various organic solvents, and the main components are benzene series, including pure benzene and toluene with considerable toxicity, as well as xylene with less toxicity.

Benzene is insoluble in water, soluble in organic solvents, and can also be used as an organic solvent itself. The ring system of benzene is called benzene ring, and the structure of benzene ring after removing a hydrogen atom is called phenyl group, which is expressed by pH, so the chemical formula of benzene can also be written as phh. Benzene is a basic raw material for petrochemical industry, and its output and technical level of production are one of the indicators of the development level of a country's petrochemical industry.

Benzene, commonly known as Tianna water is a colorless to light yellow transparent oily liquid, with a strong aromatic odor, volatilizes quickly at a long temperature and is a kind of indoor volatile organic compounds, volatile into vapor, flammable and toxic. Insoluble in water, soluble in ethanol. Ether and many other organic solvents.

The main ** of indoor benzene.

The main benzene is the organic solvent of building materials, paints, stains, printer adhesives, wallpaper, carpets, synthetic fibers, etcBenzene and toluene are often used as solvents for paints, as well as solvents, additives and adhesives for construction, decorative materials and wood-based furniture. Styrene is mainly used as a solvent for the manufacture of some insulating materials and paints.

All liquid cleaners contain toluene. Toluene and xylene are also found in wood colorants and plastic tubes. 80% of benzene** in the atmosphere is in automobile exhaust, and about 70% of benzene** in outdoor automobile exhaust.

I don't know much about the furniture, but according to the national indoor air quality standard GBT18833 standard, the standard number of benzene is less than or equal to milligrams per square meter.
