What are the environmental performances of many building materials that are nominally “zero formaldehyde†and “formaldehyde-freeâ€? The trials conducted by 29 consumer rights protection units in the country and the China National Association of Greens have shown that there is no absolute “formaldehyde-free†product. The key to purchasing products is to see whether or not to use formaldehyde without formaldehyde. From a technical point of view, many companies can achieve E0 production, but market research shows that the plate market is flooded with a large number of E1, E2 products, which has a certain relationship with the national standard requirements. Some sheet products use aldehyde-free adhesives such as soybean glue, starch glue, MDI modified glue and resin adhesive. However, this test showed that a trace amount of formaldehyde was detected on all five aldehyde-free rubber sheets, but the release amount values ​​were very low. This also indicates that the "aldehyde-free" sheet is not free of formaldehyde, but the formaldehyde is derived from the wood itself rather than the adhesive, and the environmental performance may be better. The organizers analyzed whether the sheet and flooring products are environmentally friendly and closely related to the raw materials of the board, and the environmental protection of the board is closely related to the adhesive used. In addition, many products claim to be “formaldehyde-freeâ€, but the raw materials for household building materials themselves contain formaldehyde, so there is no absolute “formaldehyde-freeâ€. The key to buying is to use adhesives without adding formaldehyde, which should be simple and not suitable during renovation. Try to choose plates, floors, furniture, etc. with high environmental protection. According to reports, the “Green Home Materials 3G Logo†launched by the China Indoor Decoration Association Green Home Environment Technology Committee was officially launched. The “Green Home†logo clearly marked the detection values ​​of formaldehyde and total volatile organic compounds, and the energy efficiency of home appliances. The grades are divided into three environmental protection grades: G1, G2 and G3.
