Difference between e0 sheet and e1 sheet Green sheet standard

Owners who have done renovations know that the board is one of the decoration materials with the most formaldehyde content. When decorating, it is necessary to purchase plates with less formaldehyde content. There are three types of eco-friendly panels on the market, namely E0, E1, and E2. Relatively speaking, E0-class formaldehyde content is the lowest, and E2-class formaldehyde content is the highest. Because many people do not understand what is the e0-level sheet and e1-class sheet, the following small series will introduce the difference between e0 sheet and e1 sheet . Unclear friends can learn about it!

First, what is e0 plate and e1 plate

In fact, the grade of the sheet refers to the level of formaldehyde contained in the finished sheet, of which the e0 level is the highest level, the highest environmental protection index, the least amount of formaldehyde, ≤ 0.5mg/L (it belongs to the world's top standard); followed by the e1 level, ≤ 1.5mg/L (in line with European standards); e2 is ≤5.0mg/L (according to domestic standards). Although the higher the level, the less the amount of formaldehyde, but the amount of formaldehyde should be used when it is used. It cannot be used in an unlimited amount because of the environmental protection standards, because the space of the house is fixed, and the superposition of the quantity will also cause the environmental protection to exceed the standard. In addition, because the e0 sheet itself does not contain adhesives and anti-moisture agents, its relative moisture resistance and toughness will also be reduced, so it is not suitable for use in wet environments such as kitchens and bathrooms.

1, environmental protection level E1

According to the national environmental protection regulations, the environmental rating of the indoor board must reach E1 level before it is up to the mark, which means it is safe and environmentally friendly, so it will not cause harm to the human body. While recognizing the quality of the plates, attention should be paid to the amount of formaldehyde released from the plates used in the furniture. The E1 environmental protection standard is a national mandatory health standard and it is a mandatory "safety standard line." E1<=1.5mg/l, that is, 1.5mg/l formaldehyde content is in line with national standards, is environmentally friendly and harmless to the human body.

2, environmental protection level E0

E0 is an international standard and is environmentally friendly, which means that the release concentration of free formaldehyde per liter of space is in line with international standards. The formaldehyde content of 0.5 mg/l in the E0 class is already a safe numerical standard. According to relevant data, the formaldehyde content of drinking water is 0.9mg/l, that is to say, the E0 standard has less formaldehyde than drinking water.

Second, environmental protection plate standard

1, according to China's environmental protection standards, the formaldehyde limit level in the sheet can be divided into three levels, namely E2 ≤ 5.0mg/L, E1 ≤ 1.5mg/L, E0 ≤ 0.5mg/L. In China, the sheet can reach the E2 standard, while the E2, E1 and E0 sheets are called the environmental protection sheet. Although the environmental protection sheet has more standard grades and wider application range, it can not completely release formaldehyde, but for the With this standard environmental protection board, consumers still cannot fully trust.

2. The formaldehyde content of the environmental protection sheet of the E0 standard cannot exceed 0.5 mg/L, which is the highest limit, and the lower limit should be the highest content of the aldehyde of the environmental protection wood, that is, the lower limit is 0.12 mg/L. Formaldehyde cannot be released, so consumers are hesitated. In any case, this kind of standard environmental protection board is much more than the standard environmental protection board. This is very gratifying.

3, the so-called "zero formaldehyde" is the production of the reaction process does not produce aldehyde; the environment will not have any pollution to the production staff, and the free formaldehyde in the sheet is less than the wood's own aldehyde content (usually 0.04mg/L-0.12 Mg/L). "Zero-formaldehyde" green sheet is in principle higher than E0.

1. The concentration of formaldehyde contained in E0 level will be lower than E1 level, while E0 sheet is more environmentally friendly than E1 sheet;

2, E0 level is an international standard, and E1 level is a domestic standard;

3. The price of E0 sheet is more expensive than that of E1 sheet.

Editor's summary: The differences between the e0 sheet and the e1 sheet and the related contents of the environmental sheet standard are introduced here, and we hope to help everyone. The board is one of several decoration materials with the most formaldehyde content in the home improvement. Therefore, it is very important to choose environmentally-friendly materials. It is very necessary for us to understand this knowledge before the renovation. For more information, you can follow this website.
