Which materials contain more formaldehyde, and which decoration materials contain formaldehyde and b

1. Plates.

Panels are indispensable materials for decoration, and the most common types of panels are MDF, eco-board and solid wood board. A lot of glue is used in the production process of these boards, but the indispensable ingredient in the glue is formaldehyde, so the formaldehyde content in these boards is very high. Among the three types of boards, MDF has the highest formaldehyde content, because MDF is made of a lot of wood chips through glue.

Solid wood boards have the lowest formaldehyde content because less glue is used in the production process.

2. Flooring.

Many people will install flooring in their homes, which not only makes living more comfortable, but also decorates the indoor environment well. Common flooring on the market is laminate flooring, multi-layer wood flooring and solid wood flooring. The formaldehyde content in these floors is also very high, take laminate flooring as an example.

The laminate floor is made of urea-formaldehyde glue, which contains a lot of formaldehyde, so the formaldehyde content of the laminate floor is also very high.

3. Plywood.

Man-based panels such as plywood, blockboard, MDF and particleboard used for interior decoration. The adhesive used in the production of wood-based panels takes formaldehyde as the main component, and the residual and uninvolved formaldehyde in the board will be gradually released to the surrounding environment, which is the main body of formaldehyde in the indoor air.

1. Man-made boards: large core board, large plywood, plywood, nine-centiboard, particleboard, medium density board, etc. Mainly contains or releases: formaldehyde, benzene, VOCs, TPI.

2. Coatings: interior wall paints, exterior wall coatings. Mainly contains or releases: formaldehyde, benzene, VOCs, TPI, chloroform, carbon tetrachloride, phenol, ammonia.

3. Paints: alkyd paint, nitro paint, polyurethane paint, various materials. Mainly contains or releases: toluene, benzene, TPI, chloroform, carbon tetrachloride, phenol, nitrobenzene.

4. Glue: fast adhesive powder, universal glue, 903 glue, 108 glue, white latex. Mainly contains or releases: formaldehyde, benzene, VOCs, TPI, chloroform, carbon tetrachloride, phenol, nitrobenzene.

5. Flooring: solid wood flooring, composite flooring. Mainly contains or releases: formaldehyde, benzene, VOCs, TPI (diiso).

6. Wall and floor tiles: through bricks, vitrified tiles, glazed tiles, ceramics, etc. There are dissolved: lead, chlorine, chromium, radon.

7. Stone: marble, granite. Mainly contains or emits: the radioactive gas radon. The above seven categories of building materials all contain gases or substances harmful to the human body to varying degrees.

As long as it is a material or finished product containing paint and glue, there is formaldehyde and benzene!

All chemical products can not be completely environmentally friendly, such as coatings, the common is latex paint, and latex paint is a chemical product, solvent additives must be used to improve product performance, and solvent additives are the volatilization of formaldehyde VOC TVOC, so home decoration used in the interior wall must pay attention to environmental protection, because the damage caused by indoor decoration pollution to the human body is very serious and irreversible, especially coatings, it is recommended to choose the most environmentally friendly mineral coatings, which are different from latex paints, and mineral coatings have excellent environmental protection coefficients, does not contain solvent additives and other chemical harmful components in latex paint, formaldehyde VOC TVOC content is negligible, Rome Bio Mineral Paint is the first to obtain the "cradle to cradle" certification of the coating product, produced in Italy, Beijing has a store, brand awareness is very high.

Formaldehyde is generally released by the decoration of new houses, floors, furniture, and wallpapers. Before moving into a new home, you must do a formaldehyde test to test whether the formaldehyde exceeds the standard, if the formaldehyde content exceeds the standard, you must not move in at this time, long-term contact with formaldehyde will harm people's health, before moving into a new home, you must do a good job of removing aldehyde measures, the following are some methods of removing aldehyde, I hope you will adopt.

1. Open the window ventilation can quickly discharge the free formaldehyde to the outdoors, as long as the local air quality is up to standard, no other pollutants will be introduced, and it is easy to use and low cost, but it needs to be insisted on for a long time, because the release life of formaldehyde is long, and it is easy to repeat the situation when the ventilation is not smooth.

2. Plants have always been considered to be a good helper for indoor air purification, but it should be clear that plants are not good at controlling formaldehyde pollution caused by indoor decoration. First of all, the absorption of harmful substances by plants is very limited, and secondly, when plants encounter high concentrations of formaldehyde, they will also be damaged to a certain extent. Although plants have little effect on removing formaldehyde indoors, they are still a good choice for beautifying the indoor environment.

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. Photocatalyst, as the name suggests, is a catalyst mentioned in our junior high school chemistry, which decomposes formaldehyde into carbon dioxide and water through light, reduces the indoor formaldehyde content, and achieves the purpose of removing formaldehyde

The formaldehyde content of these 6 materials in the decoration is the highest, so you should be cautious when buying, and you must pay special attention to those who have babies at home. 1. Plates.

Second, the floor. 3. Wooden doors.

Fourth, putty. 5. Paint.

6. Curtains:

Inferior paints or cement paints used in decoration may contain formaldehyde.

Furniture, woodworking boards, wall paint formaldehyde content is high, laminate flooring also contains formaldehyde, it is recommended to put more ventilation for a period of time, it is best to let go of a summer, the release of formaldehyde in a high temperature environment will become larger, the first 3-4 months of formaldehyde release is the largest, it is best to measure formaldehyde before living in a professional company to measure and do professional formaldehyde treatment, my home is 27 yuan a square.

1. Coatings, chemical fiber carpets, paints, etc. that use formaldehyde as preservatives.

2. Decoration materials and new modular furniture are the main causes of formaldehyde pollution. The adhesives of plywood, large core board, MDF and particleboard (shredded board) in decoration materials and furniture are released when they are heated and deliquescent, which is the main source of formaldehyde release in the room.

3. UF foam is used as an insulating material for heat and cold protection of houses. Under the action of light and heat, the foam ages, releasing formaldehyde. wall glue.

Which decoration materials are high in formaldehyde? Don't use it.

The hard-hit areas with high formaldehyde content mainly come from various adhesives, here we mainly make a distinction, such as stone glue, glass glue, putty glue, these are considered to be the easiest to ignore in decoration, and it is also the easiest to ignore, often the most problematic link, because there is a problem, you will also think that it is the unqualified material.

Generally speaking, as long as the national standard can be compounded, there is basically no big problem, but everyone's focus seems to be quite one-sided, when it comes to formaldehyde-related problems, our focus will be on the main material, but it is because of this common misunderstanding that the householder's various eyes are on the main material, thus ignoring these small bits and pieces that we can't see, but this idea is very wrong.

Because it's hard to pay attention to these subtle things, and then there's a problem, and you don't think about it. For example, who can come up with glass glue or a variety of home improvement glue brands in their minds, there should be no, most of the domestic glass glue 10-15, the American brand Dow Corning 35, so that such a high ** was squeezed to death by the domestic low price, because these materials are not purchased by the owner, but the decoration company buys, the decoration party in the invisible place with the best possibility is extremely low, as long as the strength can be guaranteed, formaldehyde is so-so. There are many places where glass glue is used in home decoration, kitchen cabinet baseboards, wall cabinet gaps, floor buckle installation, baseboard installation, every room, toilet installation in the bathroom, water retaining installation in the shower room, and sink on the balcony.

Basically, it is necessary to deal with water penetration or caulking, all of which are made of glass glue, and there is a sour smell in the air after the glass glue is played, but few people pay attention to these.

Some people say that it is wood-based panels, because I am engaged in this industry, I will give you a brief science popularization. In fact, as long as it is a legal production enterprise, there is basically no problem with the formaldehyde of the plate produced. Unless you stick to the word, it can't be helped.

Because some trees themselves will also contain trace amounts of formaldehyde. Regarding formaldehyde, as long as it does not exceed the national E1 standard (less than or equal to milligrams of liters, the dryer method is used to detect). Decoration materials have a formal test report, and the seller can provide the manufacturer's industrial production license, as long as it is not particularly outrageously low, there is basically no problem.

For example, the minimum retail of a regular brand is about 80, and what you buy at 60 will basically have problems.

Now the industrial manufacturing is very mature, is not a high-tech product, if the general brand manufacturing standards of the product is 60 yuan, you can make it for 40 yuan, then why are you not the first in this industry, buy things, look at the brand, look at the **, look at the formal information, compare and then make a decision, do not pay too much attention to the low price.

It's a bit far, I hope it can help you.

Formaldehyde is used in industry as an important raw material for the production of resins, which are mainly used as binders. Paints and coatings, various man-made panels, chemical fiber carpets, and plastic floor tiles contain a certain amount of formaldehyde, which can also come from cosmetics, detergents, pesticides, disinfectants, printing inks, paper, and textile fibers. Formaldehyde is also a product of normal metabolism in the human body.

Formaldehyde is a plasma-based poison that can bind to proteins.

Formaldehyde in decoration materials is mainly used as an adhesive.

The formaldehyde content in the woodworking board is relatively large, and all the large wooden blocks are spliced a little better, and the paint-free board is a little better.

Laminate flooring, wood flooring and bamboo flooring also contain formaldehyde, solid wood flooring is better wallpaper paste, and some use biological glue without formaldehyde.

What materials have formaldehyde in decorating a house?

1.All kinds of wood-based panels.

This kind of product is the main source of harmful gases in the whole room, especially some panels containing urea-formaldehyde resin glue, from the beginning of the production to the final use, there will be formaldehyde release, and this cycle will last up to 15 years.

2. Furniture. Although this kind of item is more environmentally friendly in the whole room, it cannot be ruled out that the release of harmful gases, especially some board furniture, the release of formaldehyde can not be ignored, so it is best to place the furniture for a period of time before entering the room, so that it can volatilize some free formaldehyde.

3. Coatings, paints and other decorative materials.

I believe that the public is more familiar with this kind of material, and it is also an indispensable item in the entire construction process, but formaldehyde additives will be added to this kind of product in the production to improve their performance, so coatings and paints are also one of the best indoor formaldehyde pollution.

4. Textiles.

Because this kind of harmful gas has the function of improving textiles, enhancing anti-wrinkles, waterproofing and other functions, it is widely used in the production of textiles, so textiles will not only emit formaldehyde, but also adsorb free formaldehyde, so textiles are also one of the sources of indoor formaldehyde pollution.

The following are the top 5 decoration materials that contain the most formaldehyde in decorating houses.

The decoration of the house contains the most formaldehyde: the first place is - MDF

Particleboard, also known as fiberboard, is a wood-based board made of wood, bamboo, straw, bagasse and other fibers bonded by glue containing formaldehyde. Veneer MDF is also known as melamine board, solid wood particleboard, and granular solid wood particleboard. The amount of formaldehyde glue per cubic meter of MDF is generally 400-500 kg.

It is one of the highest formaldehyde content of all papers.

The decoration of the house contains the most formaldehyde: the second place is - multi-layer fir fingerboard

Even other layers of solid wood fingerboard synthesized with formaldehyde glue. Fir is a cork wood that cannot be dried with steam deep degreasing, and formaldehyde-free glue cannot be used on the finger-jointed board of fir wood. Generally, the multi-layer fir finger joint board is three layers, and two of the three layers must be coated with a large amount of formaldehyde glue, and the glue content is not lower than that of the blockboard.

However, due to the exposure of the "knuckles" of fir finger joints to the air, formaldehyde is more volatile than "blockboards". Compared with blockboard, the formaldehyde content is higher, the volatility is stronger, and the natural environment protection is worse than that of blockboard.

The decoration of the house contains the most formaldehyde: the third place is - blockboard

Also known as large core board, small pieces of wood containing formaldehyde glue are spliced together in the form of extrusion, and then pasted on the upper and lower layers of the wood substrate. Woodworking board can not be used alone, it must be pasted on the panel, in this case, a total of seven layers inside and outside, that is, the middle six layers are coated with formaldehyde glue, and the formaldehyde content can be imagined.

Decorate the house with the most formaldehyde: the fourth place is - veneer

Also known as plywood, plywood or paper is coated with formaldehyde glue on thin density board or particleboard to decorate furniture surfaces. Veneer is made of "three-layer plywood + 30 line veneer" and cannot be used alone. It can only be used for blockboards, splints and fir fingerboards.

The decoration of the house contains the most formaldehyde: the fifth is - solid wood finger joint board

The same is the use of real wood as raw materials, but the glue used in the production process is formaldehyde-free, there is no threat of formaldehyde exceeding the standard, the most ideal healthy and environmentally friendly wood board, can be used in any occasion. It is a sturdy wooden door base with a usable area of 95 to 98 inches or more.

The release of formaldehyde is a slow and long process, and we all know that the release period of formaldehyde can be as long as 15 years, so the formaldehyde treatment time is a bit too long. Some owners like to pursue dull and overly heavy decorations, which is undoubtedly a measure to increase formaldehyde content. In addition, the decoration has just been completed, and the formaldehyde content exceeds the standard must also be determined.

Therefore, it is recommended that the owners and friends try to be as simple as possible when decorating, and at the same time ventilate for more than half a year after the decoration is completed, so that it is very necessary to reduce the formaldehyde content and reduce the formaldehyde concentration.
