Where does formaldehyde come from in home decoration and where is formaldehyde in decoration mainly

Living in an environment with excessive formaldehyde content will cause formaldehyde poisoning symptoms, which are generally manifested as dizziness, pungent smell, tearing, and palpitations. Long-term exposure to formaldehyde also increases the likelihood of causing cancer.

In home decoration materials, such as composite flooring, some furniture, cabinet backboards, panels, etc., the use of MDF, because the MDF is used in the urea aldehyde glue, the formaldehyde content is higher, the current state has formulated strict standards for the formaldehyde content in the MDF, so we should pay attention to the brand, origin and test report of the material when purchasing. The renovated room must also be fully ventilated and cannot be moved in immediately.

Other wood-based panels, such as large core boards, plywood, plywood, etc., have relatively low formaldehyde content due to the glue used in acetethylene.

Formaldehyde emission is an indicator of how much formaldehyde gas is released by a product. At present, the adhesive used in decorative boards is still mainly urea-formaldehyde resin, and the remaining formaldehyde that does not participate in the reaction in the board will be gradually released to the surrounding environment. Formaldehyde, the release of ammonia and radioactive pollution are the three most important sources of pollution in home decoration, especially ammonia and radioactivity, if they are not through the instrument, people can not detect their existence at all.

Therefore, you can use expert testing to determine whether the living environment has these pollutions.

plates, paints, coatings. Glue. Furniture. Rug. Wallpaper, curtains, etc. Maybe you buy qualified building materials, but you have to cumulative, so it will generally exceed the standard.

It is recommended to inspect and treat after the decoration is completed.

LEHMANN Environment can help you solve the problem of indoor air pollution caused by renovation.

Most of today's panels are produced by additives of adhesives or paint chemicals.

The paint of the decoration and furniture and the paint of the wall must not exceed the standard, if it is serious, it will be fatal and carcinogenic.

Some decoration materials, such as wallcovering, wallpaper, chemical fiber carpets, styrofoam, paints and coatings, contain formaldehyde and may be released into the home.

The adhesive of man-made boards such as blockboard, plywood, MDF and particleboard for home decoration is mainly urea-formaldehyde resin, and the residual formaldehyde in the board will be gradually released to the surrounding environment.

Furniture with low-quality adhesives can also release formaldehyde. Studies have shown that the release period of indoor formaldehyde is 3 to 15 years.

In order to protect the health of occupants, the state stipulates that the maximum formaldehyde concentration in indoor air shall not exceed 0 08mg/m3。

Because wood-based panels are the main source of excessive formaldehyde in indoor air, many countries in the world have made strict regulations on the formaldehyde emission value of wood-based panels. Our country uses Japanese fasno516-1992 standard, which clearly divides the formaldehyde emission index into 3 levels, with the highest being <10mg (jiaxing) and 100mg (plate).

Mainly used in all kinds of glue, wallpaper glue, Daxing board glue, cabinet gap glass glue, etc.

In the current decoration, due to the use of a large number of various man-made panels (particleboard, fiberboard, plywood, etc.), these boards contain formaldehyde due to the use of adhesives, especially the use of inferior adhesive boards, its formaldehyde content is higher, in addition, the production of new furniture, the decoration of the wall, the ground, all use adhesives. Wherever adhesives are used in large quantities, formaldehyde is released. In addition, some chemical fiber carpets and paints also contain a certain amount of formaldehyde.

wall paint. Wood lacquer, furniture. It is best to use spider plants (except formaldehyde).

Mainly the problem of plates, there are also paints, viscose, plastics and even curtains of fuel and shaping materials may release formaldehyde, benzene, urea and other harmful gases to the human body due to improper treatment.

But don't get too nervous, there will always be some natural ways in nature.

At least to deal with formaldehyde, you can plant a few pots of aloe vera to deal with it: aloe vera's own metabolism is to need formaldehyde, wonderful! Just use a few spider plants to deal with benzene, and cacti (balls, mountains can also deal with more).

Of course, the concentration should not be too high, and plants are the same as people, and they can't stand it if they are excessive.

Indoor formaldehyde**.

1. Man-made panels.

All kinds of wood-based panels, plywood, slender wood boards, fiberboard, particleboard and other man-made boards we use are added to formaldehyde to varying degrees in the production process.

Although the urea-formaldehyde resin adhesive with formaldehyde as the main component is toxic, it has strong adhesion, and also has the effect of strengthening the hardness of the board, insect resistance and corrosion. It is often used in the production process of wood-based panels, so the board is also a major reason for excessive indoor formaldehyde.

2. Indoors. In addition to man-made panels, furniture at home may also be one of the reasons for excessive indoor formaldehyde concentrations.

For furniture made of wood-based panels, solid wood panels and other boards, due to the binder added to the board in the production process, the assembly of the furniture may also use a cementing agent, which further increases the formaldehyde content of the furniture. In addition to panel furniture, some furniture and furniture also contain different degrees of formaldehyde.

3. Wall. Once the wall building materials such as paint and latex are not properly selected, it will also cause the indoor formaldehyde content to exceed the standard.

Wall paint manufacturers on the market will claim to be "zero formaldehyde products", in fact, the so-called "zero formaldehyde products" do not exist, and the current technology cannot reach the level of complete removal of formaldehyde. Before purchasing coating products, ask the merchant for the test certificate of the product to see what is the content of the formaldehyde testing item, according to the relevant regulations, the indoor formaldehyde concentration shall not be higher? (milligrams per cubic meter).

If the merchant refuses or cannot produce the test certificate, the environmental performance of the product can be imagined.

In addition to paint, wallpaper and latex also emit formaldehyde. It is difficult to remove formaldehyde in the wall, and the release of formaldehyde is a slow cycle, so you must see the test report before choosing wall building materials.

Where is formaldehyde mainly produced in decoration? Formaldehyde is mainly used in man-made panels, the incubation period of formaldehyde is 3 15 years, the volatilization of formaldehyde is a long-term process, and it is not at all, plus the presence of formaldehyde in furniture, textiles, etc. from time to time, and the volatilization of formaldehyde is constantly increasing, so the value will continue to increase.

That might say, I've been opening the window for ventilation, and I've put activated carbon, how can I still exceed the standard?

Although it has been ventilating and putting activated carbon, these can only play a little role, and can only adsorb free formaldehyde, and the formaldehyde on the surface of the substrate is still being continuously released, and the fundamental problem cannot be solved.

Therefore, no matter how many years of decoration or new decoration will have the existence of formaldehyde, if you want to quickly remove formaldehyde, you must use different processes and products according to different types of pollutants and their structural characteristics!

Hazards of formaldehyde: dazzling tears, mucosal inflammation, throat pain, pulmonary edema, nausea and vomiting and other respiratory diseases, while excessive formaldehyde seriously leads to female menstrual disorders, pregnancy syndrome, decreased fertility and neonatal chromosomal abnormalities, leukemia. Mental decline in adolescents.

Long-term exposure to low-dose formaldehyde pollution can lead to nasopharyngeal cancer, brain cancer, colon cancer, and high concentrations of formaldehyde also damage the immune system and liver system.

It is a fast-paced society, if we want to remove formaldehyde quickly and well. It is recommended that you can use Qingmanluyou nano photocatalyst to meet the psychological requirements of wanting to move into a new home immediately after the new decoration, and you don't have to worry about the problem of formaldehyde toxicity, and you can easily solve your family's troubles. Faster and better check-in is also what you and I need for health.

Manifestations of formaldehyde poisoning:

1. When I get up every morning, I feel stuffy, nauseous, and even dizzy 2. People often catch colds.

3. Although I don't smoke, I often feel uncomfortable in my throat, have a foreign body sensation, and have poor breathing 4. Children often cough, sneeze, and have decreased immunity.

5. There are often allergies and other problems, and they are **.

6. The family members share a disease, and after leaving this environment, the symptoms have improved, and formaldehyde poisoning is good, what should I eat?

1. Honey: Sweet in taste, flat in nature, it has been a good product for nourishing and strengthening the body and detoxifying since ancient times.

2. Radish: Carrot is a detoxifying food that can effectively reduce the concentration of mercury ions in the blood.

3. Kelp: Kelp is rich in iodine, which is very beneficial to the human body.

4. Fungus: It can adsorb the dust impurities remaining in the human body and then discharge them from the body.

5. Cucumber: It can promote human metabolism and discharge toxins;

6. Bitter gourd: sweet taste, bitter, flat in nature, traditional Chinese medicine believes that bitter gourd has the effect of detoxification and detoxification.

7. Lychee: accelerate the elimination of toxins, make ** delicate, etc.

8. Mung beans: It has the functions of clearing heat, detoxifying and dispelling fire.

9. Tea: It is rich in a bioactive substance - tea polyphenols, which has a detoxifying effect.

Formaldehyde in decoration is mainly used in furniture and floors and walls.

1. This kind of glue can make all wood residue, shredded paper, etc. into decorative building materials, and various sample materials such as particleboard, large core board, high-density board, and Aosong board commonly used in interior decoration are bonded with resin glue, so if the decoration carpenter at home is bigger, the larger the board used, the greater the probability of indoor formaldehyde, and the wooden floor inevitably belongs to this rank.

2. Part of the fabric, this kind of resin glue is also widely used in curtain fabrics, mattresses, blankets and other fabrics, because the resin glue made of formaldehyde can improve the wrinkle resistance of the cloth, fire performance, etc. Therefore, the corresponding indoor formaldehyde additives will also be added in the fabric processing, so this kind of items are with indoor formaldehyde.

3. Construction auxiliary materials, in the engineering decoration, the usual decoration company paints the so-called wall and ground solid on the wall and ground after entering the site, and this wall solid ground solid has formaldehyde components, including foam glue and structural glue added when installing window and door openings. The latex paint used in the construction of wall engineering is also an indoor formaldehyde additive, because the indoor formaldehyde additive has a certain moisture-proof and fireproof safety effect.

Decoration formaldehyde**.

1. Interior decoration of wood-based panels such as plywood, blockboard, MDF and planboard. Since the current production of decorative board adhesives is mainly urethral formaldehyde resin, the remaining and non-particulate formaldehyde will be released gradually. In the surrounding environment, it is the main body of formaldehyde in indoor air.

Furniture made of wood-based panels. In pursuit of high profits, some manufacturers use unsuitable panels and low-quality glue when using clipboard materials. As a result, the customer buys it home, which is equivalent to buying a small waste discharge station.

2。Other decorative materials containing formaldehyde can be discharged into the outside world, such as wallpaper, wallpaper, chemical fiber carpet, foam, paint, etc.

3。Some substances that release formaldehyde after combustion, such as cigarettes and some organic substances, are related to the following four factors.

1. Indoor temperature

2. Indoor relative humidity.

3. Indoor material filling degree (i.e., the surface area of formaldehyde released per cubic meter of indoor space) 4. Indoor ventilation (i.e., indoor airflow). High temperature, high humidity, negative pressure, and high load conditions all increase the emission intensity. The measurement results show that under certain conditions.

The concentration of formaldehyde in the air in a small living environment can be higher than the standard allowable level, and the release time is longer. Research from Yokohama National University in Japan shows that the indoor formaldehyde release period is 3-15 years.

Formaldehyde in decoration is mainly **in**? Man-made panels.

Formaldehyde is one of the components of adhesives, and adhesives are used in the processing of composite flooring, plywood, man-made panel furniture, etc., so the board is an important reason for excessive indoor formaldehyde.

2.wall coverings.

Improper selection of wall building materials such as paint, latex paint, and wallpaper will also cause the indoor formaldehyde content to exceed the standard, and the "zero formaldehyde products" claimed by some paint merchants on the market do not actually exist.

3.Home textiles.

Not only home building materials, but also newly bought curtains, carpets, fabric sofas, bed sheets, etc., will have an unpleasant smell, and there will also be formaldehyde. This is because in the process of textile printing and dyeing and finishing, the penetration of dyes is poor, and it is not easy to print and dye color dyes onto fabrics in an instant, and the only way is to add more binders containing formaldehyde!

If you say paint, refers to gypsum powder, then you can be very responsible to tell you that it does not contain formaldehyde, but if some glue is mixed into the paint, then the glue may contain formaldehyde, and formaldehyde is not produced in the decoration process, but in the decoration plate, which can not be confused, formaldehyde is mainly volatilized from the decoration board, and some of the chemical components used in the board are more, so the formaldehyde produced will last longer.

The content of formaldehyde has a lot to do with the decoration board, the glue used, the door, the cabinet, most of the board is a composite board, the use of glue to bond the wood sheet and the wood together, and this kind of board more or less has some formaldehyde. The volatilization rate of formaldehyde has a great relationship with the indoor temperature, the high temperature, the fast volatilization of formaldehyde, the low temperature, the slow volatilization of formaldehyde, and the speed of formaldehyde diffusion has a great relationship with the indoor ventilation. If you want to talk about the main ** of formaldehyde, the main thing is to conform to the template, and more than 50% of formaldehyde is produced by it.

And formaldehyde is a continuous volatilization process, many owners will be vacant for 1 3 months after the renovation of the house, during which they are often ventilated, the purpose is to let the continuous formaldehyde can be discharged from the room. In addition to the formaldehyde content in the board, that is, the furniture, like some special glues, wooden doors, paints, etc., also contain a certain amount of formaldehyde, but because of the different categories, the formaldehyde content is low. Moreover, there are some home decoration sewing agents used, and formaldehyde may also exist in this thing.

However, it is certain that if you say that the paint is gypsum powder, then it does not contain formaldehyde, because the paint is too cheap, and its manufacturing process is not as complicated as imagined, if you add chemical components containing formaldehyde, it has no other effect except harming people, and even increases the cost because of this, but it is said that some solid wall glue seems to contain a certain amount of formaldehyde, but so far I have not found that anyone's paint contains formaldehyde.
