Strengthen the floor release standard
Flooring production process to use adhesives, and formaldehyde is one of the main components of the adhesive, so there will be formaldehyde in the floor. In addition to formaldehyde, the floor without any other harmful substances. China's national standards on the floor of the formaldehyde emission is the implementation of mandatory environmental standards, as follows: E1 level, ≤ 1.5mg / L (dryer method), ≤ 0.12mg / L (climate box method, when used in arbitration). In line with national environmental standards of the product under normal conditions of use on the human body is no harm. Formaldehyde emission and the thickness of the floor is basically no relationship, and the production of the use of the adhesive properties of the floor and the production process. National standard GB-2001 detection criteria clear test conditions are: require the test sample of the measured surface area of 450mm2 (note that the area is not the volume, but not the thickness), while the sample with four formaldehyde-free aluminum Tape seal. Therefore, the final detection of the floor surface is released from the formaldehyde, and the thickness of the floor has nothing to do. Some businesses say that thick plate formaldehyde release is completely misleading consumption.
GB is the E1 standard environmental standard formaldehyde emission is less than 1.5 mg
Generally strengthen the composite floor formaldehyde standards E1 and E0. E1 is less than or equal to 1.5 mg per liter, E0 is less than or equal to 0.5 mg per liter. National standards E1 on the human body harmless, but usually have more ventilation.
