Decoration planks do not use a brand, but are you OK of the EO grade

In fact, depending on whether the environmental protection level of the board reaches the E0 level, it mainly depends on the adhesive used to make the board, and there is no problem for the woodworking board made of formaldehyde-free glue to reach the E0 level. The main E0 level is also not a very high level. It's just the highest of European standards.

Types of boards: 1. Solid wood boards, as the name suggests, solid wood boards are wood boards made of intact wood. These sturdy and natural textures make them the perfect choice for renovations.

However, due to the high cost of such plates and the high requirements of construction technology, they are not used much in decoration. Solid wood boards are generally classified according to the substantive name of the board, and there is no unified standard specification. 2. Splint, also known as plywood, commonly known as fine core board in the industry.

It is made of three or more layers of one-millimeter-thick veneer or sheet plate glued and hot-pressed. It is currently the most commonly used material for handmade furniture. Splints are generally divided into six specifications: 3 centiplate, 5 centiplate, 9 cleat, 12 cleat, 15 cleatboard and 18 cleatboard (1 cm is 1mm).

3. Decorative panels, commonly known as panels. It is a decorative board with a single-sided decorative function made by precision planing solid wood board into thin veneer with a thickness of about one, using plywood as the base material, and making it through an adhesive process. It is a special way in which splints exist and has a thickness of 3 centimeters.

Decorative panel is a kind of high-grade decoration material that is different from the current oil mixing practice. 4. Blockboard, commonly known as large core board in the industry. The large core board is made of two pieces of veneer pressed together in the middle.

The ** of large core board is cheaper than that of fine core board, and its vertical (distinguished by the direction of the core material) has poor flexural strength, but the transverse flexural strength is higher. 5. Particleboard is a thin board made of wood scraps as the main raw material, and then infiltrated with glue and additives pressed. According to the pressing method, it can be divided into two categories: extruded particleboard and flat-pressed particleboard.

The main advantage of this type of plate is that it is extremely cheap. The disadvantage is also obvious: extremely poor strength.

Generally, it is not suitable for making large or powerful furniture. 6. MDF, also known as fiberboard. It is a man-made board made of wood fiber or other plant fibers as raw materials, applied urea-formaldehyde resin or other applicable adhesives, and is divided into high-density board, medium-density board and low-density board according to its different densities.

The quality of different plates is also different! It is necessary to consider the quality and environmental protection level comprehensively.

E0 grade plate with a formaldehyde content of less than cubic meters of healthy and environmentally friendly boards, as long as the formaldehyde content standard belongs to E0 grade boards, which contain many types of boards, and its biggest advantage is environmental protection; However, the general solid wood panels have reached the E0 level, so there is no comparison between the two.

Which is better, E0 grade board or solid wood

E0 grade is actually a standard, the average amount of nail aldehyde emission is less than milligram liters, as long as the formaldehyde emission meets the E0 standard, it belongs to E0 grade board. E0 level board contains many types of board, and the safety standard of solid wood board is at E0 level, so the ratio of E0 level board to solid wood is meaningless.

The E0 level is the highest health indicator, and it is understood that only some European countries are strictly implementing this standard.

Solid wood board is a kind of wood made of natural wood after drying and processing, which is natural, healthy and pollution-free, and is the most suitable wood as a household material in daily life. Solid wood board is a poor conductor of heat, which can play the role of warm in winter and cool in summer, and is very safe to use.

ENF grade plates are good.

The formaldehyde emission requirements of E0 grade plates are relatively environmentally friendly and safe for ordinary decoration. Before the implementation of the ENF level, the E0 level was also the highest environmental protection standard in China. It is a better choice for general home use.

The formaldehyde emission requirements of ENF level are currently one of the most stringent environmental protection levels in the world, which is lower than the formaldehyde emission of some natural substances. There is no problem at home use, especially if there are elderly people, children, and pregnant women at home, and for people with higher requirements for indoor environment, it is recommended to choose ENF grade boards.

Advantages of ENF grade sheets:

1. The environmental protection level has reached a new high

According to the new national standard GB T39600-2021 "Formaldehyde Emission Classification of Wood-based Panels and Their Products", the formaldehyde emission of ENF grade is the highest environmental protection source positive level of the current national standard. Panels that can reach the ENF grade mean that the level of environmental protection has broken through a new high, and it is well deserved to occupy the minds of consumers.

2. The production process is more refined and "intelligently made".

The process of making ENF sheets is more strictly controlled, and the stability of the products is more guaranteed. Taking Millennium Boat as an example, as early as 2016, the company built a smart factory in Tancheng, Rizhao and other places in Shandong, with standardized process operation and real-time monitoring, greatly improving product quality, ensuring the stable quality of finished plates, and realizing automated, intelligent and green production, so that the environmental protection quality of products is in line with international standards.

Let's put it this way, at present, there are no formaldehyde-free products at all, and we can only select the suitable plate E0 grade methanol content of 5mg 100g according to the environmental protection level

E1 grade methanol content: 9mg 100g

E2 grade methanol content 30mg 100g

The higher the requirements for environmental protection level for home decoration, the more E0 level plates will be selected, and most brand boards on the market can reach the E0 level.

Grade plate refers to plate products with formaldehyde emission less than or equal to.

2.Formaldehyde-free addition refers to the board product without the addition of formaldehyde substances, which means that it does not contain formaldehyde.

3.You must know that there is no absolutely formaldehyde-free product in the world, even if it is formaldehyde-free, there will be formaldehyde from wood, but the content is very low and harmless to the human body, such as apples, beer, trees, etc.

Formaldehyde-free boards and EO-grade boards are two different environmental indicators, the main difference is whether the board is added with additives such as adhesives containing formaldehyde;

Level E0That is, the average value of formaldehyde emission is less than that, and it is also the environmental protection standard of European countries.

Formaldehyde-free addition of plates: In the production process, it is required that no adhesives and other additives containing formaldehyde shall be added, and the formaldehyde emission shall be lower, which is similar to the environmental protection level of natural wood.

Is it environmentally friendly for EO grade boards to add formaldehyde

The additive effect cannot be ignored

Only understanding the environmental protection level of the board is far from judging whether the indoor air quality is qualified. It's like 1 person smoking in a room is completely different from 10 people smoking.

According to the national standard, the concentration of formaldehyde in the indoor air shall not be higher, and the E1 grade board should only be replaced every 2 hours if the room temperature is below 23 degrees, and the use area of the E1 grade board shall not exceed 36 of the indoor area, so that the air quality can meet the standard.

In a room of about 100 square meters, put 2 large wardrobes made of E1 boards, and the formaldehyde concentration will exceed the standard; At present, the E0 grade board, which is hyped by the majority of furniture sellers, should also be under the same room temperature and ventilation conditions as the E1 board, and the usable area of the board should not exceed 200 of the indoor area, which can make the indoor air quality meet the standard.

For a 100-square-meter house, after purchasing basic E0 level furniture, the air quality can only just reach the standard, and if the floor is laid and the ceiling is installed, the air quality will be difficult to meet the standard.

Formaldehyde-free board, control formaldehyde from the source

According to the requirements of the industry standard of "formaldehyde-free wood-based panels and their products" issued by the China Forest Products Industry Association, it is required that no adhesives and other additives containing formaldehyde shall be added in the production process of formaldehyde-free wood-based panels, and the formaldehyde emission shall be lower than that of natural wood.

Therefore, formaldehyde-free boards have great advantages in terms of safety, and the formaldehyde-free board is not easy to exceed the formaldehyde content even when superimposed.

The first indoor air pollution after modern home decoration is mainly due to the fact that the glue used in wood building materials is not environmentally friendly, and a large amount of free formaldehyde is released for a long time.

E0 grade plate refers to the enterprise internal control health implementation standard formulated by the enterprise with reference to the highest health index of similar international products, that is, the average amount of free formaldehyde emission in the plate is less than or equal to milligrams.

Formaldehyde-free board refers to the board that does not add any adhesive, concealment agent, putty and other substances containing formaldehyde in the production process of man-made board, and has been tested for free formaldehyde.

A plate is qualified for environmental protection, but if it is used indoors, the accumulation of formaldehyde released by many plates will still cause indoor air pollution, and the qualified plate testing is not equal to the indoor air qualification.

If you want to achieve no pollution in indoor air and meet the standard of formaldehyde-free home, one of the suggestions is to use more formaldehyde-free boards, because the board does not release formaldehyde, which will naturally not cause the accumulation effect of toxic substances, and there is no limit on the amount of use.

No. There is no concept of "E0 level" in China's existing national standards and foreign related standards. The so-called E0 level standard in the domestic floor market refers to the enterprise internal control health implementation standard formulated by the enterprise with reference to the highest health index of similar products in the world, that is, the average formaldehyde emission is less than milligram liters, according to the news in 2010, only a few countries such as Japan and Finland implement similar standards.

Most of the solid wood finger jointed boards are E0, and only a few factories produce unqualified. No quality inspection experts can tell the difference. There is only one way, I know that a brand of plate is definitely an E0 plate. Brocade mouse.

The E0 level of the plate refers to the free formaldehyde emission of the plate, which is a very environmentally friendly board; Instead of referring to natural and environmentally friendly solid wood boards, people compare E0 grade with solid wood. At present, the core of the popular ecological board is a multi-layer board of solid wood and blockboard, and the top ten brands of the board Millennium Boat have this kind of board.
