Contains formaldehyde. The glue and paint used for bonding during the decoration process will contain formaldehyde. Formaldehyde is a good organic solvent. Paints are made from ester glues and phenolic substances that are easily soluble in organic solvents such as formaldehyde. Because formaldehyde is cheap and easy to prepare, producers use formaldehyde as the solvent for paints. There are environmentally friendly boards and environmentally friendly paints on the market, but they are not completely free of formaldehyde. It is just that the content is less after processing, and even if it does volatilize quickly, if you buy good-quality environmentally friendly materials, you don’t have to worry too much about formaldehyde pollution. There is no formaldehyde-free glue. Even environmentally friendly glues that claim to be formaldehyde-free have formaldehyde emissions within 0.1 mg/L. In fact, there is no need to get obsessed with the concept of 0 formaldehyde, because formaldehyde is everywhere in life. Some fruits contain formaldehyde, but the content is very trace.

As long as it is harmless to the human body and there is no long-term exposure, there is no need to worry. Formaldehyde is recognized by the industry as the most difficult harmful gas to control among all home decoration pollutions. The key reason is the volatilization period of formaldehyde. The volatilization period of formaldehyde is as long as 10-15 years, and the high volatilization period is also as long as 2-3 years. , that is to say, you must find a product that can continue to remove formaldehyde for 2-3 years to truly solve the formaldehyde problem. Activated carbon is a widely used aldehyde removal product. Due to its internal structure, it has strong adsorption capacity. However, the problem with activated carbon is that the saturation period is only about 20 days. If it exceeds 20 days, it will no longer have the adsorption capacity and cannot effectively remove formaldehyde. Adsorption, on the contrary, carries the risk of secondary release. Among the owners that the author has contacted, more than 40% have used activated carbon and failed to achieve the effect. Photocatalyst is a catalyst originating from Japan that can react chemically with ultraviolet rays to decompose formaldehyde (HCHO) into carbon dioxide and water. However, due to its high dependence on ultraviolet rays, it is now basically not used in Japan (the Japanese now use a Plant extracts are used to treat boards and decorations), while photocatalysts are still widely used in some domestic households. The air purifier mainly purifies the air. The air purifier has a layer of filter made of activated carbon, which can absorb a certain amount of formaldehyde. However, it has the same problem as simply using activated carbon, which quickly reaches saturation in a short period of time. Formaldehyde removal by plants "under laboratory conditions": Although plants have the ability to purify the air and remove some formaldehyde, overall, using plants to control decoration pollution is unreliable.
