Environmentally Friendly Office Starts with Panels: The Difference and Selection Between E0 Grade and E1 Grade PanelsPublish Time：2024-06-26 Clicks：107
With the continuous improvement of people's environmental awareness, environmentally friendly office has become the mainstream trend of enterprise office. As an important part of the office space, the environmental friendliness of office furniture is directly related to the health of office workers. Among the environmental indicators of office furniture, the environmental protection level of panels is the core, and E0 grade and E1 grade are the two most concerned environmental protection levels in the market. Today, we will explain in detail the difference between E0 grade and E1 grade panels, and how to choose suitable environmentally friendly panels according to the office environment.
First of all, let's clarify the definition and standards of E0 grade and E1 grade panels. E0 grade and E1 grade are mandatory standards for formaldehyde emission of wood-based panels in China. Among them, E1 grade is a national mandatory environmental protection standard, that is, all wood-based panels sold in the market must meet E1 grade or above; E0 grade is a recommended environmental protection standard, whose environmental protection requirements are higher than E1 grade, and it is currently a relatively high environmental protection grade panel standard in China.
Specifically, according to China's national standard "Classification of Formaldehyde Emission from Wood-Based Panels and Their Products" (GB/T 39600-2021), the limit value of formaldehyde emission for E1 grade panels is ≤0.124mg/m³, and that for E0 grade panels is ≤0.050mg/m³. From the data, it can be seen that the formaldehyde emission of E0 grade panels is less than half of that of E1 grade panels, and the environmental friendliness is more superior. It should be noted that some merchants in the market will promote "formaldehyde-free panels", but in fact, natural wood itself will also emit trace amounts of formaldehyde. The so-called "formaldehyde-free panels" only have extremely low formaldehyde emission, which is almost negligible. At present, there is no official standard for "formaldehyde-free grade" in China. Therefore, when purchasing, E0 grade and E1 grade should still be taken as the main reference standards.
Next, we will analyze the core differences between E0 grade and E1 grade panels. In addition to the difference in formaldehyde emission, there are also certain differences in production process, cost, applicable scenarios, etc. In terms of production process, E0 grade panels have higher requirements for raw materials, requiring high-quality wood fibers or fragments, and the use of environmentally friendly adhesives. At the same time, in the production process, it is necessary to strictly control parameters such as hot-pressing temperature and time to ensure the full release of formaldehyde. In contrast, the production process of E1 grade panels is relatively loose, and the selection range of raw materials and adhesives is wider.
In terms of cost, due to the higher requirements for raw materials and production processes of E0 grade panels, their production costs are relatively higher, and the market price is usually 10%-30% higher than that of E1 grade panels. E1 grade panels have lower costs and more affordable prices, and are currently the mainstream products in the market. In terms of applicable scenarios, due to their higher environmental friendliness, E0 grade panels are suitable for office environments with dense personnel and poor ventilation conditions, such as closed offices, conference rooms, office cubicles, etc. They are also suitable for enterprises with high environmental protection requirements, such as educational institutions, medical institutions, and infant-related enterprises. E1 grade panels are suitable for open office areas with good ventilation conditions or enterprises with limited budgets. Their environmental friendliness can meet the basic national requirements and ensure the health of office workers.
So, how should we choose between E0 grade and E1 grade panels when actually purchasing office furniture? First, clarify the ventilation conditions and personnel density of the office environment. If the office environment has poor ventilation and dense personnel, it is recommended to give priority to E0 grade panels. Although the price is higher, it can better protect the health of office workers. If the office environment has good ventilation and relatively scattered personnel, choosing E1 grade panels is sufficient, which can meet the environmental protection requirements and effectively control the procurement cost.
Second, check the test report. Whether choosing E0 grade or E1 grade panels, you should ask the merchant to provide an environmental protection test report issued by an authoritative third-party institution to confirm that the formaldehyde emission data in the report meets the corresponding standards. At the same time, pay attention to checking the validity period of the test report and the qualification of the testing institution to avoid purchasing counterfeit and shoddy products. In addition, you can also make a preliminary judgment by smelling the odor. E0 grade panels have almost no pungent odor, while E1 grade panels may have a slight odor but not pungent. If the panel has a strong pungent odor, it may be that the formaldehyde exceeds the standard, and it is not recommended to buy it.
Finally, choose regular brands and manufacturers. Panels produced by regular brands and manufacturers have more guaranteed quality and can be produced in strict accordance with national environmental protection standards to avoid false marking of environmental protection grades. At the same time, regular manufacturers have better after-sales service, and can handle it in a timely manner if quality problems are found in the panels.
An environmentally friendly office starts with panels. Choosing suitable environmentally friendly panels can not only protect the health of office workers but also enhance the corporate image and employees' work enthusiasm. When purchasing office furniture, do not only focus on the price, but also pay attention to the environmental protection grade of the panels. According to your office environment and actual needs, reasonably choose E0 grade and E1 grade panels to create a healthy, environmentally friendly, and comfortable office space.
