Does paint have formaldehyde, and does paint have formaldehyde in it

Paint generally refers to latex paint, the main ingredient of latex paint is acrylic, he uses latex as a thinner, as long as there is glue in the thing will contain formaldehyde, there is an old saying in the building materials industry "no formaldehyde is not glue", and formaldehyde can increase the service life and scrub resistance of latex paint wall.

Formaldehyde is a popular chemical product with a wide range of uses, simple production process and sufficient raw materials. It is the backbone of the methanol downstream product tree, with an annual output of about 25 million tons in the world, and 30% of the methanol is used to produce formaldehyde. However, formaldehyde is an aqueous solution with a low concentration, which is not convenient for long-distance transportation from an economic point of view, so factories are generally set up near the main consumer market.

Imports and exports** are also minimal. In industry, methanol oxidation and natural gas direct oxidation are mainly used.

The wall painted with latex paint contains formaldehyde, which must be there, but it is not the latex paint itself.

1. In decoration, the known sources of formaldehyde pollution are mostly from industrial adhesives, such as building boards that do not meet environmental protection standards, glue for wallpaper, etc.;

2. From the point of view of raw materials, latex paint is a water-based paint, which does not contain formaldehyde, but mainly contains benzene crops.

3. From the construction point of view, the wall generally needs gypsum putty to be leveled, so the problem is, when the gypsum putty is leveled on the wall, it will use glue to mix and mix to paste it on the wall, with glue, then it is not difficult to explain why the wall has formaldehyde content?

If the wall is leveled with gypsum putty, it is easy to cause formaldehyde to exceed the standard if it is not well volatilized, but generally the wall can only be painted after the gypsum putty is dry, so usually formaldehyde volatilizes quickly.

There is formaldehyde banquet in the paint. At present, the content of formaldehyde in the paint is very small, under normal circumstances, the formaldehyde content of the regular latex paint brand potato hall is less than 10mg kg, which is basically in line with the country, so the formaldehyde in the paint has little impact on the human body. And the current latex paint basically contains formaldehyde is free formaldehyde, and the content is very small, but there is very little formaldehyde in the paint, but the regular latex paint that meets the national environmental protection standards, these components can be used normally.

The role of paintPaint protects objects from corrosion, rust or discoloration from rain, moisture or harmful substances, etc. Paint can change the color of the surface of an object, and people can choose different colors according to their needs. With paint, the surface of the object can be made beautiful and long-lasting.

Painting different items or the same item with different paints can mean different meanings or rules. The molecules of the paint substance enter the voids of the wood fiber or attach to the surface of other objects, and the surface layer of the object is closed to avoid oxidation and deterioration.

Yes, paints contain more or less formaldehyde, and the state implements a mandatory standard value of 100mg kg. Formaldehyde itself is highly toxic, has a strong coagulation effect on proteins, can combine with the amino and hydroxyl groups of nucleic acids to denature, can hinder the action of gastric enzymes and pancreatic enzymes, thus affecting metabolic function, and its vapor has a carcinogenic effect on rodents.

Paint is an ancient name; Coating, is the name of modern civilization, contains more scientific and technological components, and is widely used in modern science and technology and industrial fields. However, there are some customary names for paint that are still retained, such as latex paint, primer, topcoat, etc. On October 27, 2017, the list of carcinogens published by the International Agency for Research on Cancer of the World Health Organization was preliminarily sorted out for reference, and paint manufacturing (occupational exposure) was included in the list of three types of carcinogens.

The paint contains formaldehyde, because its composition contains benzene and formaldehyde. The so-called "latex paint" containing a large amount of formaldehyde on the market is actually water-soluble paint, not latex paint, and some unscrupulous manufacturers use inferior water-soluble paint to counterfeit latex paint. Therefore, choosing genuine goods and maintaining ventilation are effective ways to prevent pollution.

First of all, you must choose a good paint, do not paint that is not environmentally friendly. Water-based paint is basically used (without any toxic and harmful solvents, diluted with water) to replace solvent-based paint, although there are many healthy and environmentally friendly water-based paints, but they are not widely used. Secondly, workers should wear masks and gloves during construction to avoid direct contact between paint and **; Open all windows for ventilation during construction.

In addition, eat more vitamin-rich foods and drink plenty of boiled water.

There is formaldehyde.

All kinds of paints are composed of film-forming substances (various resins), solvents, pigments, desiccant, and additives. Ordinary paints usually use gasoline as a solvent, epoxy iron red primer contains a small amount of xylene, dip paint mainly contains toluene, and there is also a small amount of benzene. Spray paint (nitro paint) and thinner (banana water) contain a large amount of benzene, toluene, xylene.

The main occupational hazard of paint production is the inhalation of organic solvent vapors, which makes the proportion of serious diseases such as aplastic anemia, leukemia, tuberculosis, pleurisy, quite high. Most of the painters with more than 10 years of service have symptoms of cough, fatigue, headache, chest tightness, and weakness of the limbs.

Pure powder is formaldehyde-free, but it needs to be adjusted with glue before painting the wall, and the glue contains a large amount of formaldehyde.

Regular brand latex paint is formaldehyde-free. Latex paint is generally a large area of brush on the wall, the release cycle of formaldehyde will generally last for many years, if the latex paint contains formaldehyde, then the house is a gas chamber, many years will be surrounded by a large amount of formaldehyde, so the general latex paint is formaldehyde-free.

Generally, latex paint contains benzene and other toxic volatiles, but because of the strong volatility of benzene, the smell of latex paint is very strong at first, and after a few months of placement, the probability of benzene exceeding the standard is not too great. Formaldehyde is generally hidden in the glue of panel furniture and fabric furniture. The release cycle is up to 3-15 years.

The paint for painting the wall contains formaldehyde, but the content is not high, and many paints are in line with the standard. Except for those inferior paints.

In fact, there is a way to remove formaldehyde:

Method 1Ventilation method.

Under normal circumstances, the new house will be renovated after the window ventilation for a period of time, it is best to open all the windows in the opposite direction of the house, so as to strengthen the air convection, in some times when there is no wind and less wind, if the formaldehyde concentration is too large, you can also use an electric fan to strengthen the convection. If you need to use an electric fan, the floor fan is more effective.

Method 2Plant absorption method.

Plants have a strong ability to absorb formaldehyde, such as pothos, cactus, spider plant, reed, iron tree, chrysanthemum, etc., usually, large leaf and vanilla plants have a better effect of absorbing formaldehyde, such as spider plant, tiger tail orchid, etc. Formaldehyde is a harmful substance that is released for a long time, and placing some green plants that can absorb it can reduce the formaldehyde content in the room.

Method 3Activated carbon adsorption method.

Solid activated carbon has the characteristics of many pores, formaldehyde and other harmful substances have a strong adsorption and decomposition effect, the smaller the particles of activated carbon to adsorb formaldehyde, the better the effect of formaldehyde, activated carbon is suitable for placing in small spaces such as furniture, and then cooperate with clear mangreen nano photocatalyst to remove formaldehyde, a week of irregular spraying, formaldehyde can be reduced. It can play a key role in the adsorption and decomposition of formaldehyde.

However, after a period of use, the activated carbon will be saturated, so it must be exposed to the sun and then reused, otherwise the activated carbon will lose its adsorption effect.

Method 4Drain water indoors.

There is also a simple way, which is to put a basin of water indoors, because formaldehyde is soluble in water, so put a basin of water, so that the water can absorb part of the formaldehyde, if you can, you can also put some vinegar and salt in the water.

Now the paint for painting the wall can generally choose latex paint, paint, diatom mud. Of course, wallpaper can also be used as a wall decoration material, but not paint is pasted.

Latex paint contains formaldehyde, and the paint partially contains and partially does not. Wuhan Lanshe diatom mud tells you that now only diatom mud is a formaldehyde-free interior wall paint, and it can also absorb and decompose formaldehyde.

To be precise, there is no formaldehyde-free coating, but the formaldehyde content of qualified coatings will be within a range of safety indicators, and the formaldehyde content of unqualified coatings will exceed the standard a lot. Moreover, furniture contains formaldehyde. Even if all the decoration formaldehyde content is up to standard, the small amount of formaldehyde will cause the formaldehyde to exceed the standard.

Therefore, no matter what the quality of the decoration materials purchased is after the decoration, you have to find a professional organization to deal with it, like Naga environmental protection, and you can rest assured that you can move in after the treatment is up to standard.

Wall paints contain formaldehyde, but very little. The harmful substances in paint mainly include: formaldehyde, VOC (toxic volatile gas), heavy metals (mercury, chromium, lead, etc.), toluene compounds, etc.

Generally speaking, the content of harmful substances in brand paints is relatively low, and the environmental performance is relatively good. Therefore, try to choose a good wall paint brand, and it should be environmentally friendly.

Generally, coatings will contain formaldehyde, benzene and other harmful gases. These belong to decoration pollution, it is best to do a treat, the galaxy photocatalyst reminds everyone that the number of people who die from diseases caused by decoration pollution reaches 2.2 million every year. . .

I'm glad to answer your question, the choice of decoration coatings is a very important link, because the main source of home decoration pollution is mainly furniture and coatings, followed by the soft fabric curtains you buy and the leather fabric of the sofa, these dyed all with formaldehyde, paint so as the name suggests, we all know that he is latex paint, which must contain some film-forming glue, as well as some additives, such as preservatives, anti-mildew agents, antifreeze, leveling agents, film-forming additives and so onThese are volatile organic compounds, the so-called TVOC, of course, there is also a large amount of formaldehyde, whether it is domestic or imported paints contain these things, so everyone to consider for themselves, there is or not, everyone knows it in their own hearts, right? Of course, having said so much, it is not that all coatings can not be chosen, but I want to tell you that since you have chosen this chemical product, then after the decoration, you must use some means to use ventilation to dry, do not move in immediately, for the health of yourself and your family, everyone chooses carefully.

The paint contains formaldehyde, and the general content is not too large, and it is almost the same for one or two months.

Most of them contain formaldehyde, as long as they meet national standards. Now there are some that do not contain formaldehyde, but they are more expensive.

Interior and exterior paints.

Of course, it's different.

Generally speaking, pure putty powder is free of formaldehyde, but it needs to be adjusted with glue before painting the wall, and the glue contains a large amount of formaldehyde. Therefore, painting the wall contains formaldehyde. It is recommended that you choose a brand coating produced by a regular manufacturer, and its formaldehyde content will meet the national standard and will not cause any harm to the human body.

Formaldehyde is present in the material:

1. Plates.

Plate is one of the indispensable materials in decoration, and the common boards are MDF, ecological board and solid wood board. Glue is used in the production process of these boards, and the glue contains a lot of formaldehyde, so these boards naturally contain formaldehyde. In particular, MDF contains the most formaldehyde.

2. Flooring.

Common flooring on the market is laminate, multi-layer, and solid wood flooring. Their formaldehyde content is also very high, among which the composite floor is pressed by urea-formaldehyde glue in the production, and urea-formaldehyde glue contains a large amount of formaldehyde.

3. Curtains.

In addition to wooden products will contain formaldehyde, in fact, curtains also contain formaldehyde, because curtains need to be printed and dyed when they are made, and a large amount of formaldehyde needs to be used in the printing and dyeing process. Therefore, don't rush to install the curtains you just bought, it's best to clean and dry them.

4. Mattresses.

In addition to curtains, no matter what kind of mattress on the market also contains formaldehyde, because glue is needed in the production process of mattresses. Among them, palm mats contain the least amount of formaldehyde. Therefore, when buying, we should buy materials with a small amount of formaldehyde as much as possible.

Formaldehyde mainly comes from adhesives and paints, and if the formaldehyde contained in the paint on the surface is in a free state, it can generally be emitted in a few months.

For many polymerized formaldehydes, it is almost impossible to wait for them to be completely emitted, so we can choose to use some formaldehyde removal methods to speed up the emission of formaldehyde.

Here's how:

Generally speaking, every 600g of activated carbon can adsorb 10 square meters of formaldehyde, so for some wardrobes, bedside tables and other closed furniture, 1-3 pieces of activated carbon can be placed to effectively adsorb formaldehyde in furniture;

If you want to quickly decompose and adsorb at the same time, you can spray some clear cranberry excellent photocatalyst, which can remove most of the formaldehyde substances in a week. The formaldehyde in the room can be decomposed in about a month.

It is important to note that:

In the newly renovated house, pregnant women and children should not be allowed to inhale formaldehyde, otherwise it will be extremely harmful to the body.
