What is the benzene release period in furniture?

Theoretically, the release cycle of benzene is generally about 6 months, and furniture is generally produced in advance, and benzene is almost released after more than 3 months. But there is also a kind of formaldehyde in furniture, and its release cycle is as long as three or five years or even more than ten years. Pay special attention to this.

There is no specific expiration date for the release period of benzene, and open more windows to let it volatilize.

Benzene is a highly flammable, fragrant colorless liquid at room temperature, an organic compound, and an aromatic hydrocarbon with the simplest composition. Benzene is highly toxic and is also a carcinogen. It is insoluble in water, soluble in organic solvents, and can also be used as an organic solvent in itself.

Benzene is also the basic raw material of petrochemical industry, and the output and technical level of benzene production are one of the indicators of the development level of a country's petrochemical industry.

Benzene (C H) organic compound, is the simplest composition of aromatic hydrocarbons, at room temperature is a colorless, sweet, oily transparent liquid, its density is less than water, with a strong special odor. Flammable, toxic, and a Group 1 IARC carcinogen. Benzene is insoluble in water, soluble in organic solvents, and can also be used as an organic agent itself.

The melting point is, and the boiling point is. If cooled with water, it can be condensed into colorless crystals. The chemical bond between carbon and carbon is between single bond and double bond, called large bond, so it has the properties of saturated hydrocarbon substitution reaction and unsaturated hydrocarbon addition reaction at the same time.

The properties of benzene are easy to replace, difficult to oxidize, and difficult to add. Benzene is a basic raw material for petrochemical industry. The production and technical level of benzene production is one of the indicators of the development level of a country's petrochemical industry.

The ring system that benzene has is called benzene ring, which is the simplest aromatic ring. The structure of a benzene molecule after removing a hydrogen is called phenyl group, which is denoted by Ph. Hence benzene can also be expressed as PhH.

Uses of benzene: solvents for fats, resins, iodine, etc. Determination of the mineral refractive index.

Organic synthesis. Optically pure solvents. High-pressure liquid chromatography solvents, used as raw materials for synthetic dyes, pharmaceuticals, pesticides, photographic films, and petrochemicals, diluents, paint strippers, paint strippers, lubricating oils, greases, waxes, celluloids, resins, artificial leather and other solvents.

It should be 1-2 months.

It usually takes a few years!

The release cycle of solid wood furniture is generally 3-15 years.

Therefore, if you want to protect the health of your family, you can choose Hexiang board customized furniture, which does not release harmful substances such as formaldehyde at all.

1. For new decoration and new furniture, the first 3 months are the intensive release period of formaldehyde and benzene, and formaldehyde and benzene will be released in large quantities during this period. In the absence of effective formaldehyde treatment, the probability of carcinogenic and leukemia for children under 5 years old can reach more than 95%. Because formaldehyde and benzene are internationally recognized first-class carcinogens.

This is also the reason why many decoration companies tell people that they will move in after 3 months of new houses, because they are also afraid of death. However, it is by no means equal to 3 months, and the formaldehyde will be fully released.

After 3 months, formaldehyde will continue to be released slowly, and its release will change with the change of indoor temperature and humidity. The natural attenuation rate of formaldehyde is only about 6% every year thereafter, so the release cycle of formaldehyde can be as long as 3 to 15 years.

2. In newly renovated houses that have been placed for more than one or two years, especially in rooms with new wooden furniture, there are not a few cases where formaldehyde concentrations still exceed the standard, especially in the summer high temperature, and in winter, there is floor heating to close doors and windows for a long time in the 6 months, the formaldehyde concentration is still exceeded.

3. Benzene is a highly flammable, fragrant colorless liquid at room temperature, an organic compound, and an aromatic hydrocarbon with the simplest composition. Benzene is highly toxic and is also a carcinogen. It is insoluble in water, soluble in organic solvents, and can also be used as an organic solvent in itself.

Benzene is also the basic raw material of petrochemical industry, and the output and technical level of benzene production are one of the indicators of the development level of a country's petrochemical industry.

4. Generally speaking, formaldehyde and benzene volatilize faster under high temperature conditions, so summer is the high volatile period of formaldehyde and benzene, and it is recommended to increase ventilation equipment in summer, such as exhaust fans, fresh fans, or air purifiers, to accelerate air exchange and purification, and better remove toxic gases.

Benzene and formaldehyde in new furniture are harmful substances, which are often not good for human health. Today, I will share with you the method of removing formaldehyde and benzene from furniture, I hope it will be helpful to you.

1. Plants can remove formaldehyde, although formaldehyde can be removed, but the amount of formaldehyde absorbed by it is very limited, and when the indoor concentration is high, if it simply relies on plants to adsorb formaldehyde, its dosage is very large.

3. Activated carbon to remove formaldehyde is the most commonly used way to remove formaldehyde in life, and the cost is low, but activated carbon is prone to adsorption saturation in a short period of time, and it needs to be replaced or dried after saturation. Another point to note is that if the amount of activated carbon is not enough, it will not play much role in removing formaldehyde indoors.

5. High temperature and drying can accelerate the volatilization of formaldehyde and other harmful substances, so you can take out drawers, movable furniture, mattresses, etc., to the balcony for ventilation and drying.

6. The fan can assist in opening the window for ventilation, many houses are not necessarily transparent, and the effect is not very good when the window is opened, so the fan can be used to accelerate the air flow in the room and quickly discharge the free formaldehyde in the air

In half a year to three years, benzene is an organic substance determined by the state to cause leukemia, and the price of benzene and Voc is higher than that of formaldehyde.

For 1 to 3 months, it is better to open windows for ventilation.

Furniture not only contains benzene, but also formaldehyde, the longest volatilization period of benzene can be as long as 6 months, and formaldehyde is as long as 3-15 years, so the problem of indoor air pollution must be paid attention to

15 to 30 days is a large release period, after 30 days, as long as the windows are opened frequently for ventilation, people can be occupied!!

Hello, happy to answer your questions. Theoretically, the release cycle of benzene is generally about 6 months, and furniture is generally produced in advance, and benzene is almost released after more than 3 months. But there is also a kind of formaldehyde in furniture, and its release cycle is as long as three or five years or even more than ten years.

Pay special attention to this. Hope mine is helpful to you.

For a long time, there is no specific time to say that benzene can completely volatilize clean, open more windows.
