    Now most of them also use E0 grade plates, this formaldehyde emission tends to zero, is certified by the state and the European Union, I don't know how much formaldehyde is there, but it is generally calculated as formaldehyde release. There are some well-known custom furniture brands will cooperate with some scientific research institutions to launch optimized boards, before seeing the United States launched the aldehyde removal board, environmental protection and health, but also aldehyde purification, optimize the indoor environment.

    According to the "Sanitary Standards for Formaldehyde in Indoor Air", the maximum allowable concentration of formaldehyde in indoor air is milligrams of cubic meters. At the same time, China's current E0 environmental protection standard is 5mg 100g for formaldehyde content, and 15mg 100g for E1 level.

    In Europe, environmental standards are different. Europe divides wood products into three levels according to formaldehyde emission content: E1 (formaldehyde content less than 10mg 100g), E2 (formaldehyde content less than 30mg 100g), E3 (formaldehyde content less than 60mg 100g).

    Precautions for plate decoration.

    If it is used for kitchen and bathroom and exterior bay window door casing, it is necessary to apply anti-corrosion coating on the back of the wood to prevent moisture vapor and moisture from soaking and causing moisture to return to moisture and bulge. Due to years of exposure to the sun, considering that the paint may fade, such as white yellowing is unsightly, it is recommended to consider the color problem when designing. In order to prevent the deformation of the window sleeve of the external window, it is necessary to choose a plate with a moisture content of less than 12%, and pay attention to the installation of the bottom plate firmly and the styrofoam filling densely during construction to prevent the wetting of water vapor and reduce the possibility of deformation and cracking of the window cover.

    1.E0: E0 If the building material is an E0 standard, it means that the board meets the international environmental protection standard, and the emission of formaldehyde is almost negligible).

    2.E1: E1 grade plates are national standards, and many plates in the plate market are actually E1 grades).

    3.)e2:e2≤

    2: How to distinguish the authenticity of E0 grade materials.

    1.Look for regular big brands.

    If you want to buy a real E0 grade plate, you have to go to the regular brand of the plate, after all, the brand is the carrier of quality and strength, if the big brand wants to have long-term development in the industry, it must pay attention to its own brand image, and will never risk doing something that damages its reputation.

    2.Look at the environmental label rating.

    To distinguish the authenticity of the E0 material, you can look at the grade of the environmental protection logo, generally when I buy the plate, there will be a code on the side of the board, and the code will clearly indicate the environmental protection level of the building materials, we can make a basic judgment from this.

    3.Look at the plates**.

    Because the E0 grade has the advantage of low formaldehyde emissions, the E0 grade plate will definitely be much more expensive than the E1 and E2 grades, so if you decide to buy the E0 grade plate, you must not just think about saving money and covet cheap plates.

    4.Look at the quality inspection report of the plate.

    If you really don't know how to check the authenticity of the E0 plate, there is a most direct, reliable and effective way, that is, to ask the seller to show the national test report of the plate.

    The technical requirements for national environmental labeling products - artificial wood boards stipulates that the formaldehyde emission in man-made panels should be less than milligrams of cubic meters (; The amount of formaldehyde released in wood flooring should be less than milligrams of cubic meters (. Detection Method:

    In the climate chamber method, the plate sample is placed into the climate chamber according to the specified requirements, and the air sample is extracted from the climate chamber to determine its formaldehyde content by chemical analysis method.

    Methods of removing formaldehyde: (1) Ventilation: release formaldehyde as soon as possible. First, close the room to be treated, adjust the room to a space with high humidity and high temperature, release formaldehyde to the fullest, and then open the window for ventilation to release it. You can stay for about half a year.

    2) Rely on formaldehyde removal materials: this is basically a physical adsorption method, such as activated carbon, but it needs to be changed once every two weeks. There are also materials with physical adsorption and chemical decomposition, such as coconut carbon, which contains graphene and SOD cellulase, which has a larger adsorption capacity than activated carbon and can be used for a long time.

    You can stay for about 1 month.

    3) Seal the source of pollution and prevent formaldehyde from being released: use some chemical reagents to smear on the source of pollution to form a closed film, formaldehyde will not come out, and there is a disadvantage that it is easy to damage furniture and cause chemical pollution.

    1. The national standard of the People's Republic of China "Solid Wood Parquet" stipulates that the formaldehyde emission of Class A solid wood parquet is less than and equal to 9 mg 100 grams; The formaldehyde emission of class B parquet is equal to 9 mg - 40 mg 100 grams.

    2. The "Technical Requirements for National Environmental Labeling Products - Artificial Wood Panels" stipulates that the formaldehyde emission in man-made panels should be less than milligrams of cubic meters; The amount of formaldehyde released in wood flooring should be less than milligrams of cubic meters (.

    3. The national standard of the People's Republic of China "Hygienic Standards for Formaldehyde in Indoor Air" stipulates that the maximum allowable concentration of formaldehyde in indoor air is milligrams of cubic meters.

    4. The European E1 environmental protection standard is: formaldehyde content 9mg level, and the environmental protection standard is: formaldehyde content 3mg 100g. However, with China's current E0 environmental protection standard: formaldehyde content 5mg grade is 15mg 100g.

    See if there are flaws: the surface should be clean and smooth, no burrs or processing marks, there will be no glue penetration or blackening and yellowing, and there is no curl in the whole yard.

    Look at the appearance: the appearance is more beautiful, the texture is uniform and delicate, the color is clear, the whole texture is very beautiful, the matching board and parquet are arranged in accordance with the design rules, the wood color is close, and the seams and edges can be almost the degree of the Pyeongchang brothers.

    Look at the structure of the adhesive layer: check whether there is delamination between the surface layer and the base layer, or between each layer inside, and there can be no bulging.

    See if it is environmentally friendly: If you smell a lot of smell, it means that the formaldehyde emission is high and not environmentally friendly enough.

    The use of environmentally friendly adhesives for solid wood furniture does not mean "zero formaldehyde". It's just that no formaldehyde-containing glue is used in the production process or no formaldehyde is artificially added, and it is not guaranteed that the finished product is free of formaldehyde.

    In addition, although the higher the environmental protection level of the board in the furniture, the lower the formaldehyde content, but the excessive number of furniture placed in the room will also cause the formaldehyde emission to exceed the standard. So, "zero formaldehyde" furniture almost non-existent, just a matter of how much!

    Formaldehyde in furniture mainly exists in the adhesive based on urea-formaldehyde resin, because formaldehyde has strong adhesion, can strengthen the hardness of the board, and is insect-proof and anti-corrosion. Most of the furniture on the market needs to be processed through multiple processes such as veneer, painting, and edge banding, and most of them will use adhesives containing urea-formaldehyde resin and phenolic resin, and formaldehyde is derived from this. In addition, the preservatives used to store wood also contain formaldehyde.
