What is ENF grade board? What types of board can meet this standard?
New solid wood furniture often has a strong smell. What methods can we use to remove the odor? Below are several techniques. Opening windows for ventilation is essential, but to quickly eliminate the smell, you should also employ the following methods: 1. Adsorption method (activated carbon) Adsorption is a solid surface phenomenon. It uses porous solid adsorbents to treat gaseous pollutants, where one or several components, on the solid adsorbent surface, are
ENF grade is the new environmental protection standard for board companies issued on October 1st this year, commonly known as the 'new national standard' for boards. According to this standard, the enterprise's formaldehyde-free level requires ≤0.025 mg/m³. Compared to the old national standard, although the difference is slight, it can be said to impose more stringent requirements on board production and processing enterprises. At the same time, it also means that under current standards, if enterprises want to meet the standard, they must further optimize and improve in all aspects such as raw material control, process technology, and quality inspection.
allvs, as a UK high-end customization brand, located in Guangzhou and Shanghai, China, has fully launched ENF preparation at its Asian processing center, completed ENF upgrade for all product lines in December 2021. Currently, allvs has completely phased out E0 and E1 grade raw materials. Currently, materials are only from JapanF☆☆☆☆and the higher ENF grade.
allvsProducts meeting the highest ENF standard have stricter test values than the US Carb naf zero-formaldehyde certification!
Note: Although Japan's and the US's sampling methods are slightly different from China's national standards, for example, Japan does not allow edge sealing while China allows it, it is widely recognized in the industry that the numerical requirements of the national standard are very low.
Previously, US Carb naf and Japan F☆☆☆☆ were considered the highest formaldehyde emission standards. In Carb naf, NAF stands for "No added Formaldehyde".
Because formaldehyde exists everywhere in nature, including in trees and our bodies (see below), we cannot say zero-formaldehyde (the "zero-formaldehyde" claimed by merchants is deceptive); we can only say there is no additional formaldehyde added during the production process.
