Method for detecting free formaldehyde emission of two kinds of plates

1. Perforation extraction method: E1 grade ≤ 9mg/100g.

2. Dryer method: E1 grade ≤ 1.5mg / L.

The test results of the above two methods are not directly comparable, but in general, the E1 grade plate (ie, European E1 grade plate, ≤9mg/100g) detected by perforation extraction method is subjected to the surface treatment and then detected by the dryer method. The detection value will often reach about 0.5mg/L. Comparing the detection value of the dryer method to 0.5 mg/L and the detection value of the perforation extraction method of 9 mg/100 g, it is said that the former formaldehyde content is ten times lower than the latter, which is wrong.
