Many people want to know whether the formaldehyde content in their homes exceeds the standard after decoration, because if the formaldehyde content exceeds the standard, it will cause harm to people's health. Therefore, how to know whether the formaldehyde content exceeds the standard_how to judge whether the formaldehyde content exceeds the standard is something that people who decorate their homes should know. Things containing formaldehyde are generally found in furniture, glue and other substances. Let’s learn more about it in detail.

1. How to know if formaldehyde exceeds the standard when purchasing furniture?

1. Smell. When buying furniture, if you open the inside of the furniture (such as drawers, wardrobes, etc.) and smell a strong pungent odor, accompanied by tears, itchy throat, coughing and other discomfort, it means that the formaldehyde content is seriously exceeded;

2. Look. Look at the qualification certificate. In order to promote orders, merchants usually do a certification if the product does not contain formaldehyde. If you want to see the qualification certificate but the merchant is vague and unwilling to show it, then you have to think about it;

3. Brand. Although big brands cannot guarantee that there is no formaldehyde exceeding the standard, they are still more credible than miscellaneous brands.

4. Auxiliary materials. Don't underestimate the role of auxiliary materials. Most formaldehyde exceeding the standard is caused by excessive auxiliary materials.

Although many furniture on the market have been surface treated, formaldehyde cannot be completely sealed by edge sealing. This is why many new furniture still have a strong chemical smell.

2. Which furniture contains the highest amount of formaldehyde?

1. Wardrobes, cabinets and other furniture: Most of the wardrobes, cabinets, etc. need to be painted, and a lot of paint is used. In order to ensure that the paint does not fall off, a lot of glue is also needed, so wardrobes, cabinets, etc. will emit formaldehyde;

2. In addition, solid wood furniture emits less formaldehyde than synthetic wood furniture, because many synthetic woods require formaldehyde during the processing process, so the formaldehyde content is much greater than that of solid wood furniture;

3. Laminate flooring: Laminate flooring requires the use of formaldehyde or produces formaldehyde during its processing, and it also requires the application of glue with strong adhesion to fix the floor, so it emits more formaldehyde.

4. Wallpaper: In order to make the wallpaper adhere to the wall better, glue is used, so formaldehyde is produced during the manufacturing process of wallpaper;

5. Doors: Doors need to be painted, and many doors are made of artificial wood, which uses a lot of formaldehyde during the processing;

6. Mattress: The formaldehyde in the mattress mainly comes from the coconut palm mat inside the mattress. The coconut palm mat is made of coconut palm fibers and glue pressed at high temperature. The glue used by most manufacturers contains a large amount of formaldehyde.
