What is the difference between the E0 level and the E1 level of the decorative wood board?

The previous formaldehyde emission standards for wood-based panels only had E1 and E2 levels, of which the formaldehyde emission of E1 level must be less than or equal to, which can be directly used indoors; The formaldehyde emission of E2 grade board must be less than or equal to, and the surface of the product can be used in interior decoration after being finished. In the newly issued national recommended standard, the formaldehyde emission of blockboard has been added to the new EO level standard - formaldehyde emission is less than or equal to, aiming to control the formaldehyde emission of wooden products, so as to reduce the pollution of the room and protect the health of consumers.

In fact, we all know that the reason why EO grade is more environmentally friendly than E1 grade is that less glue is used, and less glue will appear poplar veneer and the inner layer (the inner core of the woodworking board) The adhesion is not strong, and the surface of the skin board (poplar veneer) is easy to fall off, so it is recommended to pay attention to it during construction!

The relevant national testing departments have prescribed three methods for measuring the formaldehyde content of flooring - perforation extraction method, climate chamber method and dryer method. For the formaldehyde problem of the board, there are several levels of mandatory standards issued by the state, and the E0 level adopts formaldehyde-free glue technology, and the formaldehyde emission is less than that, which can be used anywhere with confidence; The emission of formaldehyde in E1 grade is less than that and can be used directly indoors; The formaldehyde emission of E2 grade is less than 5mg L, which is generally only limited to outdoor use, and indoor use must be closed; The formaldehyde emission of EX grade is greater than 5mg L, and it cannot be used indoors. Among them, obtaining E0 and E1 grades is an environmentally friendly building material that is not harmful to the human body.

The standard of how much formaldehyde content is actually no different if it is simple now.

First, the formaldehyde content is different1. E1 grade formaldehyde content mg L;

2. The amount of formaldehyde in E0 grade is mg L, and the formaldehyde emission is almost negligible.

Second, **Different:Since the environmental protection standard of the E0 level is higher than the environmental protection standard of the E1 level, the building materials that meet the E0 level ** are higher than the building materials of the E1 level.

3. Different standard levels:1. The E1 environmental protection standard is a national mandatory health standard.

2. The E0 level environmental protection standard is the highest international health standard, and the E0 standard is mostly used in European countries.

Fourth, the toughness and moisture-proof ability are different1. The E0 level plate itself does not contain adhesives and moisture-proof agents, so its moisture-proof and toughness are reduced to a certain extent.

2. The E1 grade plate contains a small amount of glue and has strong toughness.

E1 level is a compulsory testing standard issued by the state, that is, an environmental protection index that must be achieved. Only those with E1 level are suitable for interior decoration. Specific provisions can be checked for national quality inspection standards.

E0 level is a standard formulated by some enterprises themselves in recent years, and there is no such standard in the national standard. According to these companies, this is their efforts to develop, reduce formaldehyde and other pollutants in the board, higher than the E1 level index set by the state, so it is called E0 level.

This level is determined for the board, and cannot be directly used in the evaluation of the environmental protection indicators of furniture. To make furniture, not only plates are used, but also a large amount of glue is used, and glue is the main source of formaldehyde and other substances in home decoration.

Blockboard, commonly known as large core board, is plywood with a solid wood core. It is made of two veneers glued and spliced wood boards in the middle. The total thickness of the two-sided adhesive veneer of the blockboard shall not be less than 3mm.

The width of the corner defects of all kinds of blockboards within the nominal format shall not exceed 5mm, and the length shall not be greater than 20mm.

The intermediate plank is made of high-quality natural wood planks after heat treatment (i.e., drying in the drying room), processed into wood strips of a certain specification, which are spliced by a puzzle machine. The spliced wooden board is covered with two layers of high-quality veneer on both sides, and then glued by cold and hot presses. At present, most of the blockboards on the market are solid, glued, double-sided sanded, and five-layer blockboards, with a size of 1220 mm and 2440mm.

According to the quality of the material and the texture of the surface material, blockboard can be divided into "excellent product", "first class" and "qualified product". There are also enterprises that mark the plate grade as grade A, double A grade and triple A grade, but this is only a corporate behavior, there is no "3A grade" in the national standard, and this kind of marking is no longer allowed in the market.

There are many kinds of materials for the inner core of the large core board, such as poplar, birch, pine, paulownia oak, etc., among which poplar and birch are the best, with dense texture, wood is not soft or hard, strong nail grip, and not easy to deform. The texture of paulownia is softer, absorbs more water, and is not easy to dry, and the board is easy to dry and deform when the water evaporates during use. The hardwood texture is hard, not easy to press, the splicing structure is not good, the nail holding force is poor, and the deformation coefficient is large.

Environmental protection level E1.

According to the national environmental protection regulations, the environmental protection level of the indoor panel must reach the E1 level to be considered standard, that is to say, it is safe and environmentally friendly, so it will not cause harm to the human body. While recognizing the quality of the board, we should pay attention to the formaldehyde emission of the board used in the furniture. The E1 environmental protection standard is a national mandatory health standard, and it is a mandatory "safety standard line".

e1<=, that is, the formaldehyde content is in line with the national standard, is environmentally friendly, and is harmless to the human body.

Environmental protection level E0.

E0 level is an international standard and is environmentally friendly, which means that the release concentration of free formaldehyde contained in each liter of space is in line with international standards. The formaldehyde content in the E0 level is already a safe numerical standard. According to relevant information, the formaldehyde content of drinking water is, that is, the formaldehyde content of the E0 level standard is less than that of drinking water.

1. The formaldehyde concentration contained in E0 grade will be lower than that of E1 grade, and E0 grade plate is more environmentally friendly than E1 grade plate.

2. E0 is an international standard, while E1 is a domestic standard.

3. E0 grade plate** is more expensive than E1 grade plate**.

The formaldehyde emission of E1 grade must be less than or equal to, and it can be directly used indoors; The previous formaldehyde emission standards for wood-based panels were only E1 and E2, and the formaldehyde emission of E2 panels must be less than or equal to, and the surface of the product can be used in interior decoration after being finished.

In the newly issued national recommended standard, the formaldehyde emission of blockboard has been added to the new EO level standard - formaldehyde emission is less than or equal to, aiming to control the formaldehyde emission of wooden products, so as to reduce the pollution of the room and protect the health of consumers.

In fact, we all know that the reason why EO grade is more environmentally friendly than E1 grade is that less glue is used, and less glue will appear poplar veneer and the inner layer (the inner core of the woodworking board) The adhesion is not strong, and the surface of the skin board (poplar veneer) is easy to fall off, so it is recommended to pay attention to it during construction!

Generally speaking, brand cabinets are placed in the sales store with a copy of the test report for customer verification. Here Jinzhi Cabinet reminds consumers that the current testing agency does not provide E0 level test report, when you see the E0 level test report in a cabinet store, then you can have more eyes!

The current test reports are all E1 test reports, to see whether it is E0 level, you have to look at the data to speak! First of all, we have to understand that the plate is generally divided into 3 grades, E0 grade, E1 grade, and E2 grade.

E1 grade board, formaldehyde release per 100 grams is less than or equal to 9 mg, and E2 grade board, formaldehyde release per 100 grams is less than or equal to 30 mg, which is the standard plate stipulated by the state and cannot be directly used for interior decoration. If it does not even reach the E2 level, it is a substandard plate.

When looking at the E1 test report, when the number under the test result is less than or equal to 5 mg, the plate is E0!

As we all know, a lot of furniture we buy contains formaldehyde, and the grade of the board is divided from the environmental protection of the board, which is mainly based on the amount of formaldehyde released by the board. Although E0 is a stricter standard, it is only slightly better than E1.

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≤

E0 grade methanol content: 5mg 100g

E1 grade methanol content: 9mg 100g

The E0 class is more environmentally friendly than the E1 class. There is a special plate trading network, which seems to be a Chinese plate trading network, you can go and see.

The so-called E0 grade plate is the formaldehyde content, the national standard only E1 grade formaldehyde content, E0 grade is mainly the plate industry standard. The difference between E0 and E1 is the degree of environmental protection, E0 is more environmentally friendly than E1, E0 has many brands of plates, like Dawang coconut board has always insisted on independent manufacturing, the formaldehyde content of the plate is the brand of E0 grade.

The differences between E1 and E0 are as follows:

E1 is an international and domestic standard, and E0 is a top European standard.

E1 grade formaldehyde content

mg L (in line with European standards), E0 grade contains the least amount of formaldehyde, mg L (belongs to the world's top standard).

E0 grade board does not contain moisture-proof agents and does not need to be glued, so its toughness and moisture-proof ability are relatively low. E1 grade plates contain a small amount of glue and are relatively tough.

Environmental protection E1 level, which is a national standard; The EO rating is an international standard and is very environmentally friendly.

e1, that is, the national standard stipulates that the emission of formaldehyde per liter of air cannot be exceeded.

E0, that is, the international standard stipulates that the amount of formaldehyde released per liter of air cannot be exceeded.

We all know that the plate can only meet environmental protection standards in the selection, and this kind of plate is more assured to use, so we must figure it out before choosing, so what is the difference between E1 and E0 grades?

What is the difference between E1 and E0 grades?

1. The level of environmental protection is different.

E0 plate less than or equal to milligrams per liter, it can be used indoors, E1 plate less than or equal to milligrams per liter, can also be directly used indoors, E2 can be used indoors.

2. The standards are different.

E0 meets international health standards, and E1 meets China's health standards.

How to buy E0 grade plates.

1. E0 grade plate** is about 300 yuan. When choosing this kind of plate, not only in terms of appearance, but also in terms of texture, but also consider its brand, generally speaking, only well-known brands have the strength and ability to make it reach E0 level. If you don't do false publicity, you also need to pay attention to the quality and service, the image and value of the brand.

2. When purchasing, you also need to use professional tools for testing, if you just smell, the smell of E0 is relatively small, generally speaking, it is not smellable to sell fiercely, and the plates sold are ventilated on all sides, and you can't smell it, if you can smell it, this is not E0, and you can E1 is not counted. Here is a reminder that some boards may be a little fragrant, which may be to cover up the original smell of the Destruction Bureau.

3. There is a big difference between E0 grade plates, which is mainly the production of E0 plates, for example, its cost is high, and the better the quality of this plate, the more environmentally friendly. There are some miscellaneous E0 grade plates, ** are cheaper, but it is difficult to say whether they meet the E0 standard.

Summary: What is the difference between E1 and E0 grades, and the relevant content is introduced here, they have different standards and different environmental protection levels. If you want to know more about related knowledge, you can consult Qijia.com.

Summary. How to distinguish the difference between E0 and E1 platesE0 and E1 1, E0 plates have the least formaldehyde content, and E2 plates have the most formaldehyde content. 2. E0 grade plate is more environmentally friendly than E1 plate, and E0 grade plate is more expensive than E1 plate.

3. There are three grades of plates, which are E0, E1 and E2 grades. The amount of formaldehyde per 100 grams of E0 grade plate is less than 3 mg, the amount of formaldehyde per 100 grams of E1 plate is less than or equal to 9 mg, and the amount of formaldehyde per 100 grams of E2 plate is less than or equal to 30 mg. Unqualified plates cannot be used for interior decoration, and if the requirements do not reach the E2 level, it is a bad board.

How to distinguish the difference between E0 and E1 platesE0 and E1 1, E0 plates have the least formaldehyde content, and E2 plates have the most formaldehyde content. 2. E0 grade plate is more environmentally friendly than E1 plate, and E0 grade plate is more expensive than E1 plate. 3. There are three grades of plates, which are E0, E1 and E2 grades.

The amount of formaldehyde per 100 grams of E0 grade plate is less than 3 mg, the amount of formaldehyde per 100 grams of E1 plate is less than or equal to 9 mg, and the amount of formaldehyde per 100 grams of E2 plate is less than or equal to 30 mg. Unqualified plates cannot be used for interior decoration, and if the requirements do not reach the E2 level, it is a bad board.

1. The environmental protection level is different, among them, the E1 level environmental protection standard is a national mandatory health standard, its formaldehyde content is in line with the national standard, environmental protection is harmless and will not cause harm to the human body, so in accordance with the relevant provisions of the national environmental protection, the environmental protection level of the indoor plate must reach the "standard line" of E1. The environmental protection level of E0 is higher, it is an international standard, that is, the release concentration of free formaldehyde contained in each liter of space is in line with the international standard, so the degree of environmental protection is higher, and the formaldehyde content of the E0 standard plate is even lower than that of drinking water. 2. The formaldehyde content is different, and formaldehyde cannot be released, so the formaldehyde content in the board is a very important consideration, so the selection of environmentally friendly materials is also to minimize the formaldehyde content in the environmental protection board of the E1 standard can not be exceeded, which is the upper limit.

For E0, its standard is higher, the upper limit is, that is, the formaldehyde content of the E0 standard environmental protection board can not be exceeded, in addition to this upper limit, the lower limit of E0 is 12mg L, and this 12mg L is the * content of formaldehyde in the environmentally friendly wood itself. 3. Relatively speaking, the E1 grade plate will be cheaper, but the E1F0 yuan design is enough for the national standard of environmental protection materials, so it is more in use. In terms of plates, E0 will be more expensive, and it will contain less formaldehyde content, so it is also an important choice to meet higher standards in terms of environmentally friendly materials.
