What materials contain formaldehyde and why do they contain formaldehyde

Do it? Find it online!

It is generally available in composite materials. Because of the adhesive inside, it contains a lot of formaldehyde. So people generally go to buy solid wood flooring. "Original", no adhesives.

Formaldehyde is contained in materials with formaldehyde, such as adhesives, paints, MDF, leather, etc.

1. Artificial boards such as plywood, blockboard, medium-density fiberboard and particleboard used for interior decoration;

2. Furniture made of man-made panels, unqualified panels are used, and inferior non-environmentally friendly glue is used when bonding the surface;

3. Some wallpapers, wall coverings, chemical fiber carpets, foam plastics, paints and coatings that do not meet environmental protection requirements.

4. Some materials that emit formaldehyde after combustion, such as cigarettes and some organic materials; It can even be said that as long as the glue is used, it is formaldehyde-free and non-glue.

Like flooring, paints, paints, furniture will release formaldehyde. However, the formaldehyde content of general good products will not exceed the standard, and it will not cause harm to the human body, but if you buy unqualified products, you should pay attention.

flooring, paints, paints, furniture.

As long as the glue is used, there are formaldehyde-free and non-glue.

Paint Painted with paint.

In furniture decoration, formaldehyde is mostly emitted from flooring, furniture, and paint. Formaldehyde exceeding the standard should be treated in a good way

1. Herbal Dialin management.

2. It is important to open windows and furniture doors frequently for ventilation.

3. Purchase a formaldehyde removal air purifier.

4. Buy some activated carbon or bamboo charcoal to adsorb formaldehyde.

5. Buy a few pots of green plants, such as spider plants, etc.

As we all know, the renovated house will produce some special pungent odors, if the smell of formaldehyde has been inhaled excessively by everyone, it will produce slight nausea and vomiting, cold and cough, and serious will also cause diseases and dangers. I believe we all know that many interior decoration materials contain formaldehyde in use, and we have been advocating environmentally friendly decoration, so we should understand it in the early stage to facilitate the later treatment. So what are the formaldehyde in decoration materials?

Here's what to tell you about.

Home armor aldehyde**

Formaldehyde is actually the product of the unstable decomposition of aldehyde resin adhesives, because adhesives are widely present in home improvement materials, so they become unavoidable harmful substances. So it's fair to say that any material with an adhesive in home improvement, whether it mentions formaldehyde or not, can be a potential release of formaldehyde.

Decoration materials containing formaldehyde

1. Traditional particle board and MDF are traditional formaldehyde users, because they need to glue wood chips to provide strength, and the glue content of these materials is amazing. However, it is precisely because these materials have become too mature to become the focus of special attention, and now these particle boards have relatively complete regulations and solutions. As long as you pay attention to the formaldehyde grade of the particle board, there are clear ...... E0, E1, E2, E3The hierarchy of the division.

In other words, this traditional material is a very low limit, and junk products may be infinitely dangerous, but there are already high-quality products that are clearly monitorable and reliable.

2. Strengthen multi-layer composite wood flooring. If underfloor heating is used, formaldehyde emissions will be significantly increased, but whether it reaches a higher level of harmfulness is still controversial, but the increase in emissions is certain.

3. Multi-layer solid wood board, theoretically, multi-layer solid wood is also a better and safer material than particle board, and theoretically the glue required is less than particle board, and the performance is much stronger than particle board. But there are also problems similar to Hexiang boards, which are good and very bad.

4. Wall paint. In fact, the formaldehyde of paint is currently the most transparent of these materials, as long as you don't buy fakes, it is customary to generally divide into several grades, domestic, domestic foreign brands, imported high-end brands. Personally, I think that the paint should focus on the quality of the paint, not the formaldehyde content, because in fact, the harmful content has long been not the weak point of the brand wall paint.

However, wall paint is the hardest hit area of the "formaldehyde hazard" publicity, and each brand is claiming that the brand is worse than its own toxic hazard.

5. Furniture adhesive. Wood paint, foam adhesives, solid wood finger bonding, these things are ignored by everyone, resulting in a skyrocketing of formaldehyde. And the formaldehyde release cycle of this ** is also more than several years.

Formaldehyde is very harmful to the body, especially children. Therefore, after renovating or buying new furniture, it can only be used after ventilation and deodorization. When buying new furniture or decoration materials, it is best to choose a big brand with quality assurance, relatively speaking, the content of formaldehyde will not be too much.

After the decoration, it is recommended that everyone just dry it as much as possible, and ventilate the room, and place some materials and plants in addition to formaldehyde. The above is a detailed introduction to which formaldehyde is contained in decoration materials, I hope it can help you.

1. Formaldehyde in textiles. Formaldehyde is mainly used in fiber products as a dyeing aid and a resin finishing agent to improve the anti-wrinkle and anti-shrinkage effect. Formaldehyde printing and dyeing auxiliaries are more cotton textiles, and most of the cotton anti-wrinkle clothing or non-iron shirts on the market use formaldehyde-containing auxiliaries, which may release formaldehyde when worn.

Formaldehyde in children's clothing mainly comes from dyes and additives that maintain the color of children's clothing, as well as adhesives used in garment printing. As a result, the formaldehyde content of bright and printed clothing is generally high, while the aldehyde content of plain clothing and non-printed children's armor is low.

2. Formaldehyde in food. Present in aquatic foods. Because formaldehyde can keep the color of the surface of the water food bright, it can increase toughness and crispness, improve the taste, and can also preservative, if it is used to soak seafood, it can fix the seafood form and maintain the color of the fish.

The main aquatic foods that have detected formaldehyde in the market are: duck paw, beef shutters, shrimp, sea cucumbers, fish maw, pomfret, octopus, cuttlefish, hairtail, squid head, hoof tendons, sea snails, snail meat, cuttlefish larvae, etc., among which the formaldehyde content in shrimp, sea cucumber and squid is higher. Found in pasta, mushrooms, or soy products.

Formaldehyde can whiten and change color, so formaldehyde is often used by unscrupulous traders to fumigate or directly add to pasta, mushrooms or soy products. Formaldehyde has been detected in related foods such as shiitake mushrooms, mushrooms, rice noodles, vermicelli, yuba, etc.

Formaldehyde in indoor air.

3. Formaldehyde in the air of family travel. 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.

Furniture made of wood-based panels. In order to pursue profits, some manufacturers use substandard boards, or use inferior glue when bonding veneer materials, and the formaldehyde in the boards and glues seriously exceeds the standard. Other types of decorative materials that contain formaldehyde and may be emitted to the outside world, such as wall coverings, wallpaper, chemical fiber carpets, paints and coatings, etc.

4. Formaldehyde in chemicals. Formaldehyde can come from cosmetics, detergents, pesticides, disinfectants, preservatives, printing inks, paper, etc.

5. Formaldehyde generated. When foam slats are used as heat-proof, cold-proof and insulating materials for houses, under the action of light and heat, the foam ages and deteriorates to produce synthetic compounds and release formaldehyde. Hydrocarbons can generate formaldehyde gas through photochemical synthesis, organic matter can also form formaldehyde through biochemical reactions, and also contains a large amount of formaldehyde in combustion exhaust gas, such as 7kg of formaldehyde gas can be generated for every 1000L of gasoline burned, and even formaldehyde gas is generated when a cigarette is lit.

6. Formaldehyde in automobiles. Formaldehyde also comes from interior decoration materials such as seat covers, cushions and headliners, with the most prominent formaldehyde emission in new cars.

7. Formaldehyde in air pollution. Formaldehyde also comes from the high pollution of outdoor air, such as industrial exhaust gas, automobile exhaust, photochemical smog, etc., which can be emitted or produce a certain amount of formaldehyde to a certain extent.

Decorate something that has formaldehyde.

Wood-based panels, paints, adhesives, textiles, etc. contain a certain amount of formaldehyde during decoration. Among them, wood-based panels are the main formaldehyde, and these wood-based panels use formaldehyde-based adhesives in the production process, and the free formaldehyde in these boards will be slowly released during decoration, thus becoming the main body of formaldehyde in the indoor environment.

How to avoid formaldehyde in interior decoration.

1. If you want to avoid the production of formaldehyde in interior decoration, the first thing you need to pay attention to is air circulation. In the process of decoration, the air flow can be enhanced by the layout design or knocking out part of the interior wall, and the house can be designed to be integrated with the outside, so that there can be more flowing air. However, be careful not to set up partitions near doors and windows, otherwise the air will be blocked.

2. Reasonable arrangement of indoor lighting can also effectively avoid formaldehyde production, because if there is enough light in the room, its anti-mildew effect is great, and it can effectively kill harmless substances.

3. In the use of color in interior decoration, it is best to focus on environmental protection and purity, and too bright colors can not be too much, and these bright colors can be matched with pure and environmentally friendly colors. For example, grassland green, ocean blue, or natural white, etc. In addition, when choosing furniture, we should also pay attention to avoid formaldehyde pollution, and try to choose environmentally friendly furniture.
